Description

Pad liner for brake devices {PAD LINER FOR BRAKING APPARATUS}

The present invention relates to a pad liner for a brake device. More specifically, it can be common and applied to brake calipers of various specifications, and not only improves elastic recovery force, but also makes it easier for the driver to change the brake pad. It relates to a pad liner for a recognizable brake device.

Generally, the caliper of a brake device for braking is in close contact with the brake disc when the pedal is pressed to provide braking force, and is composed of a plurality of parts.

Among these, pad liners have new specifications depending on the size and thickness of the brake disc, so not only do mold production costs required for production continue to arise, but there is also a problem in managing derived specifications due to difficulties in commonizing parts. In addition, there is a problem that when the external force on the brake pad is removed and the brake pad is separated from the brake disc by elastic restoring force, the separation is not properly achieved, resulting in a situation where the brake pad and the brake disc are in local contact. Therefore, there is a need to improve this.

The background technology for the present invention is disclosed in Korean Patent Publication No. 10-2009-0006564 (Title of the invention: Brake pad mounting structure for automobile disc brakes, Publication date: January 15, 2009).

The present invention was created in response to the above-mentioned need, and can be shared and applied to brake calipers of various specifications, and not only improves elastic recovery, but also allows drivers to easily recognize when to replace brake pads. The purpose is to provide a pad liner for a brake device.

In order to achieve the above object, the pad liner for a brake device of the present invention includes: a pair of body parts in contact with a torque member and arranged to be spaced apart from each other; Insertion parts each connected to the main body and into which the torque member protrusion of the torque member is inserted; a guide portion extending from the insertion portion to one side, contacting a brake pad, and guiding movement of the brake pad; a support portion that extends bent from the guide portion to one side and supports the brake pad; a first return portion extending from a side of the insertion portion toward the guide portion and providing an elastic restoring force to the brake pad; and a second return portion extending from a side of the main body toward the brake pad and providing an elastic restoring force to the brake pad.

In addition, the first return part may include a first return plate part extending from a side of the insertion part facing each other in the direction of the guide part; and a first return inclined portion extending obliquely in a direction away from the first return plate portion.

In addition, the first return portion is bent toward the support portion at an end of the first return inclination portion and further includes a first return notification portion that contacts the brake disc when the brake pad is worn.

In addition, the second return portion may include a second return plate portion bent and extending in a direction away from each other on sides of the main body portion facing each other.

In addition, the second return portion is bent toward the brake disc at the end of the second return plate portion and includes a second return notification portion that contacts the pad friction portion of the brake pad when the brake pad is worn. .

Additionally, the insertion portion may include a first insertion plate portion bent and extending from an end of the main body toward the front of the main body; a second insertion plate portion bent and extending from an end of the first insertion plate portion in the direction of the guide portion, and having the first return portion on sides facing each other; and a third insertion plate portion that extends bent from an end of the second insertion plate portion to the rear of the second insertion plate portion, faces the first insertion plate portion, and is connected to the guide portion.

The pad liner for a brake device according to the present invention is formed as a pair to be fitted into each torque member projection of the torque member, so it can be shared and applied to brake calipers of various specifications.

In addition, the present invention provides elastic restoring force to two points of the brake pad through the first return portion and the second return portion, so that not only is the elastic restoring force improved, but the elastic restoring force is not properly provided due to the unstable behavior of the brake pad, so the elastic restoring force is restored to its original state. This has the effect of preventing the brake pad from coming into contact with the brake disc.

In addition, the present invention provides that when the pad friction part is worn beyond a set thickness due to long-time use of the brake through the first return notification unit of the first return unit, when the brake pad is moved in the direction of the brake disc, the first return notification unit contacts the brake disc to reduce noise. This has the effect of allowing the driver to recognize when it is time to replace the brake pads and replace them quickly.

In addition, the present invention provides that when the pad friction part is worn beyond a set thickness due to long-time use of the brake through the second return notification unit of the second return unit, when the brake pad is moved in the direction of the brake disc, the second return notification unit is connected to the pad friction unit of the brake pad. This has the effect of worsening the driver's brake pedal feel by contacting it, allowing the driver to recognize when it is time to replace the brake pads and replace them quickly.

In addition, the present invention provides a pad liner for a brake device when the first return portion and the second return portion are restored to their original state by elastic restoring force through a stopper portion that extends bent from one side of the second insertion plate toward the torque member and is in close contact with the torque member.

Specifically, the brake pad 20 includes a pad support portion 21 and a pad friction portion 22. The pad support unit 21 includes a pad support main body (not shown) and a pad protrusion (not shown). The pad support body can be moved in combination with a piston (not shown). The pad protrusions extend from both ends of the pad support body and are inserted into the guide portion 130. The pad friction portion 22 is attached to the pad support portion 21 and comes into contact with the brake disc 30 to provide friction.

The support part 140 extends bent from the guide part 130 to one side and supports the brake pad 20. The support portion 140 extends bent from the lower end of the guide portion 130 (see FIG. 3 ) toward the brake pad 20 and supports the brake pad 20 when the brake pad 20 moves.

The first return portion 150 extends from the side of the insertion portion 120 toward the guide portion 130 and provides elastic restoring force to the brake pad 20. The first return portion 150 is a pair and extends downward from the side of the insertion portion 120 (refer to FIGS. 3 and 4). The first return portion 150 is made of an elastic material and is disposed between the brake pads 20, and when the external force on the brake pad 20 provided by the piston is removed, the brake pad 20 is moved by elastic restoring force. is guided to be separated from the brake disc 30.

The first return portion 150 includes a first return plate portion 151 and a first return inclined portion 152. The first return plate portion 151 extends from the opposite side of the insertion portion 120 in the direction of the guide portion 130. That is, the first return plate portion 151 extends downward from the opposite side of the insertion portion 120.

The first return inclined portion 152 extends obliquely from the first return plate portion 151 in a direction away from each other. The first return inclined portion 152 extends obliquely from the first return plate portion 151 toward the guide portion 130 at a predetermined angle.

The first return unit 150 further includes a first return notification unit 153. The first return notification unit 153 is formed to be bent toward the support unit 140 at the end of the first return inclined unit 152. That is, the first return notification unit 153 is formed to be bent downward from the end of the first return inclined unit 152 (based on FIGS. 3 and 4). This first return notification unit 153 serves to notify the driver of the replacement time of the brake pad 20 by contacting the brake disc 30 and generating noise when the pad friction unit 22 is worn (FIG. 9 reference). Because of this, the driver can recognize when to replace the brake pads 20. In addition, the first return notification unit 153 has a shape bent toward the support unit 140, thereby serving to reduce resistance when the first return inclined unit 152 is restored to its original position by elastic restoring force.

The second return unit 160 is located above the first return unit 150. The second return unit 160 includes a second return plate unit 161. The second return plate portion 161 extends bent in a direction away from each other on opposing sides of the main body portion 110.

That is, the second return plate portion 161 is bent in a direction away from the brake disc 30 at the opposing side of the main body portion 110.

The second return unit 160 further includes a second return notification unit 162. The second return notification unit 162 is formed to be bent toward the brake disc 30 at the end of the second return plate unit 161. This second return plate portion 161 serves to notify the driver of the replacement time of the brake pad 20 by contacting the brake disc 30 and generating noise when the pad friction portion 22 is worn beyond the set thickness ( 10). In addition, when the pad friction portion 22 is worn beyond the set thickness, the second return notification portion 162 contacts the pad friction portion 22 of the brake pad 20, making it difficult for the driver to operate the brake pad 20. so that you can feel it. In other words, the driver may perceive that the brake pedal feel has worsened. Because of this, the driver can recognize when to replace the brake pads 20. At this time, the second return notification unit 162 may serve to notify the driver of the replacement time of the brake pad 20 by contacting the brake disc 30 and generating noise (see FIG. 10). In addition, the second return notification unit 162 has a shape bent toward the brake disc 30, thereby serving to reduce resistance when the second return plate unit 161 is restored to its original position by elastic restoring force.

The insertion portion 120 includes a first insertion plate portion 121, a second insertion plate portion 122, and a third insertion plate portion 123. The first insertion plate portion 121 extends bent from the end of the main body portion 110 toward the front of the main body portion 110. The second insertion plate portion 122 extends bent from the first insertion plate portion 121 in the direction of the guide portion 130, and is provided with a first return portion 150 on the sides facing each other.

The third insertion plate portion 123 extends bent from the end of the second insertion plate portion 122 to the rear of the second insertion plate portion 122, faces the first insertion plate portion 121, and is connected to the guide portion 130. do. The torque member protrusion 11 protruding from the torque member 10 is inserted into the space formed through the first insertion plate 121, the second insertion plate 122, and the third insertion plate 123.

In this way, the pad liner 200 for the brake device is formed as a pair to be fitted into the torque member protrusion 11 of the torque member 10, so even if the size and thickness of the brake disc 30 vary, the torque member (10) In other words, it can be applied to brake calipers of various specifications. For example, even if the thickness of the brake disc 30 changes from a to b and the specifications of the torque member 10 change, the pad liner 200 for a brake device of the present invention can be applied (FIGS. 11 and 12 reference). In other words, the pad liner 200 for the brake device can be shared and installed on the torque member 10 of various specifications.

The insertion portion 120 further includes a stopper portion 124. The stopper portion 124 extends toward the torque member 10 from opposite sides of the second insertion plate portion 122 and is in close contact with the torque member 10 (see FIGS. 4 and 5). Specifically, the stopper portion 124 is in close contact with the torque member 10 inserted into the insertion portion 120 by elastic restoring force to increase the coupling force between the torque member 10 and the pad liner 100 for the brake device. As a result, even if the first return unit 150 is restored to its original state by elastic restoring force, the horizontal movement of the brake pad liner 200 is limited, and the brake pad liner 100 can be prevented from being separated to the outside. there is.

The stopper part 124 includes a first stopper part 124a and a second stopper part 124b. The first stopper portion 124a is made of an elastic material and extends bent at a predetermined angle from opposite sides of the second insertion plate portion 122 toward the torque member 10 (Figure 3, 4).

The second stopper portion 124b extends bent from the end of the first stopper portion 124a to the outside of the torque member 10 and is in close contact with the torque member 10. In this way, the second stopper part 124b extends bent from the end of the first stopper part 124a to the outside of the torque member 10, so when the stopper part 124 is in close contact with the torque member 10, Damage to the torque member 10 can be reduced due to the stopper portion 124.

The insertion portion 120 further includes an insertion compression portion 125. The insertion pressure portion 125 is formed on the first insertion plate portion 121 and is in close contact with the inserted torque member 10. This insertion pressure portion 125 is in close contact with the inserted torque member protrusion 11 to increase the coupling force between the torque member 10 and the pad liner 100 for the brake device.

The insertion compression portion 125 includes a compression hole portion 125a, a compression contact portion 125b, and a compression inclined portion 125c. The pressure hole portion 125a is formed from the main body portion 110 to the first insertion plate portion 121. The pressure contact portion 125b extends from the main body 110 and is located in the pressure hole portion 125a. The compression inclined portion 125c extends from the lower end of the compression contact portion 125b (based on FIG. 3) toward the third insertion plate portion 123. The compression inclined portion 125c is made of an elastic material and can compress the torque member protrusion 11 inserted into the insertion portion 120 by elastic restoring force. Specifically, the compression inclined portion 125c is elastically deformed when the torque member protrusion 11 is inserted into the insertion portion 120, but is returned to its original state by the elastic restoring force when the torque member protrusion 11 is inserted into the insertion portion 120. As it is restored, it comes into close contact with the torque member protrusion (11) and presses it. As a result, the coupling force between the insertion portion 120 and the torque member protrusion 11 increases.

The insertion portion 120 further includes an insertion guide portion 126. The insertion guide portion 126 extends from the side of the third insertion plate portion 123 and protrudes toward the first insertion plate portion 121, that is, upward (based on FIGS. 3 and 4) with an inclination. Because of this, when assembling the brake pad 20 to the guide part 130, the brake pad 20 can be easily guided to the guide part 130 and assembled. Additionally, when the torque member protrusion 11 is inserted into the insertion portion 120, the horizontal movement of the torque member protrusion 11 may be restricted.

The guide portion 130 includes a guide plate portion 131 and a guide stopper portion 132. The guide plate portion 131 extends to one side from the third insertion plate portion 123 and is connected to the support portion 140. The guide plate portion 131 extends downward from the end of the third insertion plate portion 123 (based on FIGS. 3 and 4) and comes into contact with the torque member 10.

The guide stopper portion 132 is formed on the guide plate portion 131 and protrudes forward of the guide plate portion 131 to limit separation of the brake pad 20. The guide stopper portion 132 may protrude forward of the guide plate portion 131 by machining holes on both sides of the guide plate portion 131. As a result, the pad protrusion of the pad support portion 21 disposed close to the guide plate portion 131 is caught by the guide stopper portion 132, thereby limiting movement and preventing it from deviating to the outside of the guide plate portion 131.

The brake device 1 according to the present invention has the same configuration installed opposite the torque member 10 on which the pad liner 100 for the brake device is installed, and the operation and effect of the configuration are also the same, so detailed description is omitted.

Hereinafter, the operation and effects of the brake device 1 according to an embodiment of the present invention will be examined with reference to FIGS. 5 to 10.

The torque member protrusion 11 formed on the torque member 10 is inserted into the insertion portion 120. At this time, the stopper part 124 and the insertion pressure part 125 are elastically deformed by the torque member protrusion 11 inserted into the insertion part 120, and when the torque member protrusion 11 is inserted into the insertion part 120, As it is restored to its original state by elastic restoring force, it comes into close contact with the torque member protrusion (11) and puts pressure on the torque member protrusion (11).

When the torque member 10 and the insertion part 120 are combined, the brake pad 20 is installed. The pad protrusion of the pad support portion 21 moves along the guide portion 130 by the operation of the piston. At this time, the first return inclined portion 152 of the first return portion 150 elastically supports the edge of the pad support portion 21.

When the driver operates the brake pedal (not shown), hydraulic pressure is transmitted to the torque member 10. The piston presses the brake pad 20 toward the brake disc 30 by hydraulic pressure (see FIG. 7). In this way, the brake pad 20 is in close contact with the brake disc 30 and generates friction. At this time, the first return unit 150 is elastically deformed by the pressure of the brake pad 20.

Conversely, if the driver does not operate the brake pedal when releasing the brakes, hydraulic pressure does not apply to the piston, and the elastic restoring force of the first return unit 150 and the second return unit 160 restores the brake pad 20 to Ensure that the pad 20 is sufficiently spaced from the brake disc 30. The brake pad 20 is spaced apart from the left and right sides of the brake disc 30 (based on FIG. 7) by the first return unit 150 and the second return unit 160. At this time, since the stopper part 124 is in close contact with the torque member 10 inserted into the insertion part 120 by the elastic restoring force, even if it is restored to its original state by the elastic restoring force of the first return part 150, the brake device The pad liner 100 can be prevented from being released to the outside. In addition, by sufficiently separating the brake pad 20 from the brake disc 30, a drag phenomenon due to contact friction between the brake pad 20 and the brake disc 30 can be prevented.

If the pad friction portion 22 is worn beyond the set thickness due to long-term use of the brake, the second return notification portion 162 causes the pad friction of the brake pad 20 when the brake pad 20 moves in the direction of the brake disc 30. By contacting the part 22, the driver can feel difficulty in operating the brake pad 20, so that the driver can recognize when to replace the brake pad 20. At this time, the first return notification unit 153 may come into contact with the brake disc 30 and cause noise (see FIGS. 9 and 10). Because of this, the driver can recognize the replacement time of the brake pads 20 and replace them quickly.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those skilled in the art will recognize that various modifications and other equivalent embodiments are possible therefrom. You will understand.

Therefore, the true technical protection scope of the present invention should be determined by the scope of the patent claims below.
