In this context, the following description describes a disc brake caliper that is attached to the frame 1000 of a bicycle is mounted, as an example of the human-powered vehicle. It should be understood, however, that the disc brake caliper can be mounted on any other human-powered vehicle. The example also shows the disc brake caliper 10 that on the chain stay 1001 of the frame 1000 is mounted and is therefore part of a rear disc brake. The disc brake caliper 10 however, it can also be used on another structural element of the frame 1000 mounted, such as one on the frame 1000 rotatably arranged front fork, which is part of a front disc brake.

When reference is made in the following to the terms "front, rear, top (top), bottom (bottom), left and right", these terms refer to the state in which the disc brake caliper is attached to a human-powered vehicle, especially the frame of a bicycle, with the rider of the vehicle sitting and facing a handlebar (the front).

The disc brake caliper 10 has a saddle body 12 on. The saddle body 12 is in a first section (first half) 12a and the second section (second half) 12b (please refer 5 ) divided.

The saddle body 12 can be mounted on the human-powered vehicle, in the present example a chain stay 1001 of the frame 1000 of a bicycle. For this purpose, the saddle body 12 a mounting surface 14th on that on one mounting side 16 of the saddle body 12 is arranged towards the human-powered vehicle (see 7th ).

A first mounting hole 18th defines a first mounting axis 18a . The first mounting hole 18th is on the mounting surface 14th for fastening the saddle body 12 provided on the human-powered vehicle via a first fastening element (see 5 and 7th ). The first mounting hole 18th defines a first attachment opening 18c in the mounting surface 14th . The first fastening element can be a threaded bolt 20th his. The first mounting hole 18th has a threaded hole 18b to accommodate the threaded bolts 20th as the first fastening element.

A second mounting hole 22nd defines a second mounting axis 22a . The second mounting hole 22nd is on the mounting surface 14th for fastening the saddle body 12 provided on the human-powered vehicle by means of a second fastening element (see 5 ). The second mounting hole 22nd defines a second attachment opening 22c in the mounting surface 14th . The second fastening element can be a threaded bolt 24 his. The second mounting hole 22nd has a threaded hole 22b to accommodate the threaded bolts 24 as a second fastening element.

The mounting surface 14th has a first section 14a and a second section 14b on, being the second section 14b from the first section 14a is separated (see 7th ). So are the first section 14a and the second section 14b separated and one room 34 is between the first section 14a and the second section 14b trained (see 1 and 4th ).

In particular, the first mounting hole 18th and the second mounting hole 24 on the first section 14a or the second section 14b intended.

In this example, the mounting surface is 14th (the first paragraph 14a and the second section 14b) a frame mounting surface 1002 on top of the chain stay 1001 of the frame 1000 facing (see 1 and 5 ). Also is the frame mounting surface 1002 in a first section 1002a and a second section 1002b divided that the first section 14a and the second section 14b the mounting surface 14th of the saddle body 12 correspond. For fastening the disc brake caliper 10 on the human-powered vehicle are the threaded bolts 20th as the first fastening element and the threaded bolt 24 as a second fastening element from below into the through holes 1003a and 1003b in the chain stay 1001 of the frame 1000 inserted and into the threaded hole 18b of the first Mounting hole 18th and the threaded hole 22b of the second mounting hole 22nd screwed in. When tightening the threaded bolts come 20th and 24 , the first paragraph 14a and the second section 14b the mounting surface 14th with the frame mounting surface 1002 , especially the first section 1002a and the second section 1002b (please refer 5 ) in touch. This allows the disc brake caliper 10 be reliably attached to the human-powered vehicle.

How out 3 can best be seen, the first axis of attachment extend 18a and the second mounting axis 22a perpendicular to the mounting surface 14th , in particular to the surface of the first section 14a or the second section 14b . Furthermore, the second fastening axis 22a parallel to the first mounting axis 18a . Also the surface of the first section 14a and the surface of the second section 14b can be parallel.

In addition, the disc brake caliper 10 a first piston 26th on that of the saddle body 12 along a first piston axis 26a not parallel to the first mounting axis 18a in response to hydraulic flow from a hydraulic hose 100 is movably supplied (see 5 and 6th ). In the embodiment shown, the first piston axis is 26a perpendicular to the first mounting axis 18a and thus to the second mounting axis 18b as well as the connection axis described later 56a . The disc brake caliper 10 , especially the second section 12b of the saddle body 12 , can be a first piston cylinder 28 exhibit. The first piston 26th is in the first piston cylinder 28 housed and within the first piston cylinder 28 along the first piston axis 26a movable. A first piston ring 30th is in a groove 28c between an inner peripheral wall 28a (the jacket of the cylinder) of the first piston cylinder 28 and an outer peripheral surface 26b of the first piston 26th arranged. Thus there is a first hydraulic chamber 32 between an inner surface 26c of the first piston 26th and a floor 28b of the first piston cylinder 28 defined (see 6th ).

An outside surface 26d of the first piston 26th opposite the inner surface 26c is in contact with a first brake pad 36 with a first support plate 36a . The first support plate 36a wears a first brake shoe 36b .

In addition, the disc brake caliper 10 a second piston 38 on that of the saddle body 12 along a second piston axis 38a not parallel to the first mounting axis 18a in response to hydraulic flow from a hydraulic hose 100 is movably supplied. The second piston axis 38a is coaxial with the first piston axis 26a .

The disc brake caliper 10 , especially the first section 12a of the saddle body 12 , can have a second piston cylinder 40 exhibit. The second piston 38 is in the second piston cylinder 40 recorded and within the second piston cylinder 40 along the second piston axis 38a movable. A second piston ring 42 is between an inner peripheral wall 40a (the jacket of the cylinder) of the second piston cylinder 40 and an outer peripheral surface 38b of the second piston 38 arranged. Thus there is a second hydraulic chamber 44 between an inner surface 38c of the second piston 38 and a floor 40b of the second piston cylinder 28 defined (see 6th ). The floor 40b is through a lid 40d formed, the releasable on the first section 12a of the saddle body 12 is attached.

An outside surface 38d of the second piston 38 opposite the inner surface 38c is in contact with a second brake pad 46 with a first support plate 46a . The first support plate 46a carries a second brake shoe 46b .

Between the first brake pad 36 and the second brake pad 46 , the one with the first support plate 36a and the second support plate 46a is in contact is a pad spacer 48 arranged. The pad spacer 48 is an elastic spring element that holds the first brake pad 36 and the second brake pad 46 pushing away from each other.

For easy maintenance, in particular the replacement of the brake pads, the first brake pads are used 36 , the pad spacer 48 and the second brake pad 46 through a pen 50 detachable on the saddle body 12 attached. How out 5 best seen is the pin passes through it 50 the first section 12a of the saddle body 12 , the second support plate 46a , the pad spacer 48 , the first support plate 36a and the second section 12b of the saddle body 12 . The pencil 50 is with a bracket 52 fixed. After releasing the clamp 52 can the bolt 50 removed and the first and second brake pads 36 , 46 be replaced.

In addition, the saddle body 12 also a receiving slot 53 on, which is used to hold a disc rotor 103 the disc brake of the human-powered vehicle is designed (see 1 , 2 and 8th ). The receiving slot 53 is between the first section 12a and the second section 12b of the saddle body 12 educated. The first brake pad 36 and the second brake pad 46 are in the receiving slot 53 arranged and the disc rotor 103 is between the first brake shoe 36a and the second brake shoe 46a arranged (see 8th ).

The saddle body 12 points next to the mounting surface 14th also a pad 54 on that on the mounting side 16 offset to the mounting surface 14th is arranged.

Furthermore, the saddle body 12 a hose connection hole 56 for fastening the hydraulic hose 100 on. The hose connection hole 56 defines a connection axis 56a . It also defines the hose connection hole 56 a hose connection opening 56b in the connection surface 54 .

In addition is the hose connection hole 56 at the connection surface 54 intended. This is the hose connection hole 56 on the fastening side 16 of the saddle body 12 offset from the mounting surface 14th in the direction of the first piston axis 26a intended.

In particular, the fastening surface is on the first section 12a of the saddle body 12 and the pad 54 and the hose connection hole 56 on the second section 12b of the saddle body 12 arranged. The receiving slot is thus located 53 between the mounting surface 14th and the hose connection hole 56 .

The connecting axis 56a extends in the direction of the first piston axis 26a (please refer 3 ) essentially perpendicular to the mounting surface 14th . The term “significant” in this context includes deviations of ± 5 ° from the vertical alignment.

In addition, the connection axis 56a and a plane P through the center of the receiving slot 53 (please refer 6th and 8th ) not crossing. In this context, the mounting surface 14th and / or the connection surface 54 be arranged perpendicular to plane P.

There is also the hose connection hole 56 provided so that the connection axis 56a not with the first mounting axis 18a overlaps in each direction. In one embodiment, the hose connection hole is 56 provided so that the connection axis 56a parallel to the first mounting axis 18a runs (see 8th ).

In addition is the hose connection hole 56 closer to a median plane 1004 of the human-powered vehicle as the attachment surface 14th in a state in which the saddle body 12 is attached to the human-powered vehicle (see 8th ). In other words, it is the hose connection hole 56 on an inside of the saddle body 12 arranged that of the median plane 1004 facing the human-powered vehicle.

The hose connection hole 56 also has a threaded hole 58 on, that for receiving a connection element for fastening the hydraulic hose 100 at the hose connection hole 56 is designed. The connection element is a banjo connection screw 60 to pass through a banjo 102 at one end of the hydraulic hose 100 and having a fluid passage configured to be in fluid communication with the hose connection hole 56 to stand.

As already described, the hydraulic hose 100 a banjo at one end 102 on. The banjo 102 is an annular element with an opening 104 in its inner peripheral surface. The banjo terminal screw 60 pierces the banjo 102 . As a result, the banjo can 102 around the banjo connector screw 60 rotate, with the connecting axis 56a is the axis of rotation. Thus, the longitudinal alignment of the hydraulic hose 100 by turning the hydraulic hose 100 at its end the the banjo 102 has to the connection axis 56a be changed.

The banjo terminal screw 60 has a smaller diameter section 60b between a head 60a and a threaded end 60c (please refer 6th ). The section 60b smaller diameter has a smaller diameter than the thread end 60c and / or the head 60a . The thread end 60c is picked up and in the threaded hole 58 attached. The section 60b the smaller diameter communicates with the opening 104 in the inner peripheral surface of the banjo 102 .

Furthermore, the banjo connection screw 60 a lower hole 60d on that extends from an area 60e at the end of the thread 60c in the section 60b with a smaller diameter extends. In addition, the section 60b with a smaller diameter an opening 60f in its outer peripheral surface, that with the lower hole 60d is connected.

This allows hydraulic fluid to flow out of the hydraulic hose 100 through the opening in the inner peripheral surface of the banjo 102 in a space between the inner peripheral surface of the banjo 102 and the outer peripheral surface of the smaller diameter portion 60b stream. The hydraulic fluid can flow from this space through the opening 60f in the lower hole 60d and finally into the hose connection hole 56 stream.

In addition, the disc brake caliper 10 one in the saddle body 12 trained hydraulic channel system 62 to the hose connection hole 56 and with it the hydraulic hose 100 with the first hydraulic chamber 32 and the second hydraulic chamber 44 to connect fluidically. The Hydraulic duct system 62 exhibits a variety of channels 62a up to f and is best off 6th evident. In this context is the channel 62d in a first screw 64 integrated to the first section 12a on the second section 12b of the saddle body 12 to fix. Another screw 66 which does not have such a channel can additionally be provided around the first section 12a and the second section 12b to attach to each other.

When the disc brake is actuated, for example by means of a brake lever, hydraulic fluid is fed through the hydraulic hose via the banjo connection screw (see above) 100 into the hose connection hole 56 pressed. The fluid then flows through the channel 62a into the first hydraulic chamber 32 and through the channels 62b to f in the second hydraulic chamber 44 .

As a result, the first piston 26th and the second piston 40 along the first piston axis 26a and the second piston axis 40a in response to hydraulic flow from the hydraulic hose 100 through the hydraulic duct system 62 moved towards each other. This will be the first brake shoe 36b and the second brake shoe 46b against the disc rotor 103 pressed and provide a braking force.

MODIFICATIONS

As mentioned above, the present embodiment will be described with reference to a disc brake caliper that is attached to the chain stay 1001 of the frame 1000 of a bicycle is mounted. However, the disc brake caliper can also be attached to the fork of the frame 1000 of a bicycle, in particular on a rear side of the fork.

In the above embodiment, the disc brake caliper 10 directly on the human-powered vehicle, especially on the frame 1000 , assembled. However, it is also conceivable to provide an adapter or a base element between the saddle body 12 and the human powered vehicle is arranged so that the disc brake caliper 10 is mounted directly on the human-powered vehicle. In particular, the saddle body 12 on the adapter or base element and the base element in turn on the human-powered vehicle, such as the frame 1000 , be mounted. Further details on this and how such a base element could be designed can be found in the US 9,347,505 B2 whose content, in particular that of the basic element, is incorporated by reference in its entirety.

The above embodiment was with two opposing movable pistons, the first piston 26th and the second piston 38 , described as a so-called fixed brake caliper. But it is also possible to design the disc brake caliper with only one movable piston as a so-called floating caliper.
