Description

[Detailed Description of the Invention] This invention relates to an improvement of an engine mount for mounting an engine on the chassis side of an automobile.

Conventionally, this type of engine mount has been used under severe usage conditions, and various types of engine mounts have been adopted as measures against vibration and noise.

Some of these engine mounts have a lock at the bottom end of the engine mount block in order to suppress the vibration range of the engine within a certain range and to maintain the mounting position of the engine when the housing and mounting rubber are excessively deformed. A stopper having a pair of legs is fixed, and the stopper is connected to the chassis button and the engine mount within a certain range of the engine itself.
Some models have a structure that makes contact with two parts of the bracket, regulating the vertical range of engine vibration.

However, if an engine mount with such a stopper is used, it will not only be able to withstand longitudinal and lateral vibrations of the engine, but also with respect to vertical vibrations. First, the engine itself vibrates vertically in an inclined state depending on various conditions such as the state of the road surface, and therefore the engine maw, /) (7) A stopper having a pair of legs fixed to the lower end of the block. As a result, only one leg functions as a stopper at a time when it is not originally needed, and unreasonable force is applied to the stopper, and vibrations from the engine are transmitted to the body, impairing riding comfort. When mounting the engine to the vehicle chassis via a mounting bracket, the above problem may also occur if the top and bottom gaps between the stoppers differ for each engine mount due to manufacturing or assembly errors. was.

is formed.

A block 12 having a trapezoidal cross section is attached to the box portion 16 of the sonoengine mount bracket 11 via mounting rubber 13.13.

That is, the mounting rubber 13 is made of vulcanized rubber that has excellent oil resistance, heat resistance, weather resistance, and fatigue resistance, and one side of the mounting rubber 13 is attached to the box part 1 of the engine mount bracket 11.
6 side, and the other side to the side surface of the block 12 by gluing or baking.

A stopper 14 is attached to the lower end of the block 12 by a bracket 19 formed in a substantially U-shape and having pin holes 20 formed on both sides thereof.

The stopper 14 has a stopper main body 21 with a thick inner shape at the center, a horizontal pin hole 22 formed in that part, and a pair of legs 23.23 extending laterally from both ends of the stopper body 21. It is composed of stopper rubbers 24, 24, 25, and 25 attached to the upper and lower surfaces of the end portions of .23 by adhesion, baking, or screwing, respectively.

That is, the stopper 14 is constructed by welding or bolting a bracket 19 to the lower end of the block 12 in advance, fitting the center portion of the stopper body 21 into the bracket 19, and inserting the pin 26 into the pin holes 20 and 22. It is attached.

. Of course, the positions of the stopper 14 attached to the lower end of the block 12 and the stopper rubbers 24.25 attached to both ends of the legs 23.23 are aligned with the stopper surface 18 of the engine mount bracket 11. It is configured to be placed at an appropriate distance below the .

The engine mount 10 configured in this manner has the upper end of the block 12 welded or bolted to the lower end of the engine 40 as appropriate, and the flange 17° 11 of the engine mount bracket 11 to the appropriate location on the chassis 41. They are fixed to the engine 40 side and the chassis 41 side by welding or bolting in place, respectively.

Therefore, engine 40 is now being operated and engine 4
0 vibrates in a tilted state, the stopper rubber 24 of the stopper 14,
25 comes into contact with the top surface of the chassis 41 or the stopper surface 18 of the engine mount bracket 11, the stopper 14 will tilt around the pin 26, and the engine mounting position will not be within the predetermined range. Only when the stopper rubber 24, 25 of the stopper 14 contacts the upper surface of the chassis 41 or the stopper surface 18 of the engine mount bracket 11, the stopper function is performed.

FIG. 2 shows another example 50 of the stopper 60 attached to the engine mount according to this invention.

In this engine◆mount 50, the engine mount bracket, mounting rubber, and block are the same as those in specific example 10 shown in FIG. do.

A stopper 60 attached to the lower end of the block 12
has a thick inner shape at the center, and a spherical surface 63 on the inner side of that part.
A stopper body 61 is formed with a vertical bolt hole 62 as shown in FIG. Stopper rubber 65.65.66.66 attached by baking or screwing etc.
It is attached to the lower end of the block 12 by a bolt 67 with a spherical surface 63 formed on the shank, a washer 68, a rubber link 69° 70, and a nand 71.

That is, rubber rings 69 and 70 are arranged at the upper and lower ends of the bolt hole 62 of the stopper body 61, respectively, and the bolt 67 is inserted from below the bolt hole 62 through the washer 68, so that the stopper body 61 is assembled with the bolt 67. It is loosely clamped, and the tip of the bolt 67 is screwed into the lower end of the block 12 and fixed with a nut T1.

Of course, the positions of the stopper 60 attached to the lower end of the block 12 and the stopper rubbers 65 and 66 attached to both ends of the legs 64 and 64, respectively, are determined by the engine mount bracket 11. It is configured such that it is arranged at an appropriate interval below the stopper surface 18 of.

In order to mount the engine 40 on the chassis 41 side using the engine mount 50 configured in this way, a hole 72 is formed in advance at an appropriate position on the chassis 41 side to which the engine mount 50 is attached. Then, position the engine mount 50 on the chassis 41 so that the head of the bolt 67 that attaches the stock bar 60 is accommodated in the hole 72, and place the upper end of the block 12 on the engine 4.
The flange 17.1 of the engine mount bracket 11 is welded or bolted as appropriate at the lower end of the housing.
7 is welded or bolted onto the chassis 41.

Therefore, engine 40 is now being operated and engine 4
When the engine 40 vibrates in a tilted state, the stroke rubber 65.
Even if either one of the bolts 66 comes into contact with the upper surface of the chassis 41 or the strike bar surface 18 of the engine mount bracket 11, the strike bar 60 will tilt around the spherical surface of the shank of the bolt 67, and the engine mounting Only when the position changes beyond a predetermined range, both stopper rubbers 65 and 66 of the stopper 60 move toward the chassis 41.
By contacting the top surface of the engine mount bracket 11 or the bottom surface 18 of the engine mount bracket 11, the S7 function is performed.

Furthermore, even if an error occurs in the assembly of the engine mount and the gap between the strike bar rubber 55, 66 and the strike bar surface 18 of the bracket is uneven, the stopper will swing and have a self-adjusting function. As a result, the stopper is not biased.

Of course, the range of inclination of the tension bar 60 is adjusted depending on the tightening of the bolt 67 and nut 71.

According to this invention, the lower end of the engine mount block is equipped with a stopper that can be tilted in response to engine vibrations, so even if the engine is tilted and vibrates, the engine mounting position remains unchanged. The setting range of the engine can be held constant, and the stroboba effect can be applied appropriately only when the mounting position of the engine changes beyond the setting range.
