Definitions
- the present invention relates to a brake pad holder of a disc brake of a motor vehicle, in particular a commercial vehicle, according to the preamble of claim 1 and a disc brake and a brake pad.
- the brake linings are based on these brake carrier horns, depending on the direction of rotation of the brake disc.
- the inlet-side carrier horn while the rear carrier horn is called in a main direction of rotation of the brake disc, so the direction of rotation of the brake disc during a forward drive of the motor vehicle.
- the front carrier horn is referred to as the outlet side carrier horn in a main direction of rotation of the brake disc, so the direction of rotation of the brake disc during a forward drive of the motor vehicle.
- the known from the prior art brake pads usually have on their side facing away from the axis of rotation of the brake disc upper edge of a pad retaining spring, which is supported via a lining shaft opening of the brake caliper spanning pad holder radially outward.
- This pad retaining spring serves on the one hand to compensate for tolerances occurring and for damping the brake pads to protect against jerky load that can damage the connection of the friction mass to the lining carrier plate.
- the pad retaining springs also serve to reduce rattling noise of the brake pads during driving. In the absence of the movable bearing between the caliper and the brake carrier and the simultaneous connection of the brake caliper with the brake pads or the brake pads would also contribute to the above-mentioned forces acting on the respective support surfaces between the brake pad and brake carrier, in particular as reaction force in Rüttelbelas- lines.
- the brake carrier In order to prevent such an oblique wear, the brake carrier would have to be replaced, which would be associated with high material and processing costs. In order to prevent digging of the brake pads in the contact surfaces of the brake carrier, it is known to harden the brake carrier horns. However, this measure is associated with a high production and cost. In addition, this method can lead to a distortion of the brake carrier, which would jeopardize the maintenance of function-relevant tolerances and, where possible, would result in a more difficult mounting of the brake.
- a disc brake is known in which by a special shape of the brake pads and the wearer carrier of the brake carrier and the kinematic design and the ratios of the attacking force components, these disc brakes are able to brakes in both the brakes discontinuously positioned brake carrier horns as well as via a positive connection directly into the einlaufsei- positioned brake carrier horns or detours via friction and higher reaction forces in the brake or the brake carrier to initiate.
- This positive connection between the brake pad and the brake carrier on the inlet side carrier horn can be prevented at a forward braking decelerating braking operation with simultaneous positive connection of the caliper with at least one of the brake pads.
- Object of the present invention is to develop a generic brake pad holder such that with an acceptable bias of the brake pads both a slight displaceability of the caliper is guaranteed as well as an acceptable damping of the caliper and a To ensure protection of the heavily loaded support surfaces between the brake pads and the brake carrier horns.
- a brake pad is spring-loaded on at least one side of a brake disc, a brake pad in a lining shaft of a stationary brake carrier with the brake lining laterally enclosing brake carrier horns.
- the brake pad has at least one friction lining and a lining carrier plate carrying the friction lining. From an inlet-side edge of the lining carrier plate, a projection which projects in the assembled state of the brake lining in a lateral recess of an inlet-side carrier horn of the brake carrier extends.
- a spring element is arranged with two elastic ends.
- a first end of the spring element is designed so as to support the brake pad radially relative to an axis of rotation of the brake disc close foot region of the inlet side carrier horn to the axis of rotation of the brake disc.
- a second end of the spring element is designed to support the brake pad with respect to a rotational axis of the brake disc remote support the head portion of the inlet side carrier horn radially to the axis of rotation of the brake disc.
- the spring element is positively or non-positively fixed to the inlet side carrier horn.
- two of the inlet side carrier horn encompassing first tabs are particularly preferably formed. Such tabs can be formed on the spring element in a simple manner.
- as a simple assembly and management of the spring element on the inlet side carrier horn allows.
- the first end of the spring element is preferably supported in the mounted state on one of the axis of rotation of the brake disc facing functional surface of the lining carrier plate as functional surfaces serve preferably the axis of rotation of the brake disc facing bottom of the projection and / or a region of the lining carrier plate, which extends below the projection for the axis of rotation of the brake disc facing the lower edge of the lining carrier plate extending toward.
- the second end of the spring element is preferably formed bent in the head region of the inlet side carrier horn.
- the unloaded state is the second end of the spring element on the head portion of the inlet side carrier horn while it just bent in the loaded state against the spring force of the second end between the head portion of the inlet side carrier horn and the edge of the brake pad 2 rests and so not alone from the first end of the spring element Catchable vibrations dampened.
- the spring element is formed according to a further preferred embodiment as a leaf spring or wire spring and thus easy and inexpensive to produce and particularly suitable for installation in a narrow gap between the inlet side carrier horn and the inlet side horn facing side horn of the brake pad.
- the first end of the spring element is preferably arc-shaped, in particular s-shaped.
- a head region of the intake side Bremschihorns near edge of the lining carrier plate is formed with a radially from the brake carrier horn radially from the axis of rotation of the brake disc increasingly removing contour.
- the spring element in the application direction of the brake pad is slidably fixed to the lining carrier plate. This has the advantage that with each brake pad change a new spring element must be mounted necessarily, and thus optimal function of the caliper guide over the life of the brake is guaranteed.
- two second lugs embracing the lining carrier plate are preferably formed on the spring element. These tabs preferably have holes for receiving a fixed to the lining carrier plate connecting element.
- the spring element has a slot-shaped recess in the application direction of the brake lining for receiving a connecting element fixed to the lining carrier plate.
- the surface of the spring element is hardened according to a further advantageous embodiment variant. This results in the area of the brake carrier horns, which are preferably made of cast material, a further improved protection against burial.

- Figure 7 is a perspective view of a brake pad with assumed spring element.
- the reference numeral 1 designates a brake carrier of a disc brake of a motor vehicle, in particular of a commercial vehicle, the brake carrier 1 essentially comprises a base body 11 and carrier horns 12, 13 arranged on the outlet side and outlet side, between which Brake pad 2 is held.
- the brake pad 2 has at least one friction lining 22 and a lining carrier plate carrying the friction lining 22, as shown by way of example in FIG.
- a (not shown) disc brake disc facing away from the edge 28 of the lining carrier plate 21 is a lining holder spring 4 is verliergesichtert and held radially deflectable.
- This pad retaining spring 4 is here, contrary to the usual positioning centered on the edge 28 of the pad carrier plate 21 here in the region of the outlet side carrier horn 13 facing half of the edge 28 of the pad carrier plate 21 positioned.
- This pad retaining spring 4 is supported radially upwards on a pad retainer (also not shown) spanning the pad shaft of a caliper, not shown, which is detachably fixed to a brake caliper, not shown, of the disc brake, for example.
- the brake carrier 1 itself is fixedly mounted on the vehicle housing or a component of the vehicle axle.
- the brake disk (not shown) rotates together with a wheel axle of the motor vehicle during a forward movement of the motor vehicle in a main direction of rotation D.
- a spring element is disposed between the inlet side edge of the lining carrier plate 21 and the inlet side brake horn 12 3 arranged.
- This spring element 3 has two elastic ends 31, 31, which are connected to each other by one of the contour of the inlet-side edge of the lining carrier plate 21 following Mitteilteil.
- the spring element 3 is designed as a leaf spring in the embodiment variant shown here. Also conceivable is the design of the spring element 3 as a wire spring.
- a projection 23 which, in the assembled state of the brake lining 2, protrudes into a lateral recess 14 of the inlet-side carrier horn 12 of the brake carrier 1, so that the brake lining 2 is moved by a pivoting movement into the running side carrier horn 12 and the outlet side carrier horn 13 in the circumferential direction of the brake disc limited lining shaft of the brake carrier is used.
- the first end 1 of the spring element is designed to support the brake pad 2 with respect to an axis of rotation of the brake disc near foot region 15 of the inlet side carrier horn 12 radially to the axis of rotation of the brake disc.
- this first end 31 of the spring element 3 is preferably arcuate, in particular S-shaped.
- an end piece of the first end 31 is supported on a functional surface 27 of the carrier plate 21.
- this functional surface 27 is formed as a slightly beveled region extending towards the inlet-side edge of the lining carrier plate 21, in relation to the circumference of the brake disk extending towards the rotational axis of the brake disk.
- Another functional surface 26 of the carrier plate is formed by the underside of the projection 23 facing the axis of rotation of the brake disk, against which a supporting surface 36 of the spring element 3 abuts.
- the spring element is bent here s-shaped, the lower arc rests on the foot portion 15 of the inlet side carrier horn 12 and thereby the brake pad 2 on the inlet side Bremsharihorn 12 resiliently supported.
- a second end 31 of the spring element 3 is designed to radially displace the brake pad 2 against a head region 16 of the inlet side carrier horn 12, which is remote from an axis of rotation of the brake disc Support the axis of rotation of the brake disc.
- the second end 32 of the spring element 3 is, as can be clearly seen in FIGS. 1 and 2, formed bent toward the head region 16 of the inlet-side carrier horn 12.

In the loaded state, the second end 32 is pressed against the spring force of the second end 32 just bent between the head portion 16 of the inlet-side carrier horn 12 and the edge of the brake pad 2. Since the second end 32 of the spring element 3 is particularly preferably designed to be relatively short, a significantly higher force is required for straight bending of this bent second end 32 than for deformation of the first end 31 of the spring element 3. Thus, a total of two-step cushioning of the brake pad 2 by the Spring element 3 allows.
- the spring element 3 is positively or non-positively fixed to the inlet side carrier horn 12.

- a displacement of the lining carrier plate 21 relative to the spring element 3 held stationary in the application direction Z is made possible.
- a second tab 37 is formed on the Abstütz- surface 34 of the spring element 3, which surrounds the lining carrier plate 21 of at least one side.
- a connecting element 5 is fixed in the lining carrier plate 21, in this case on a side parallel to the friction surface of the brake disc back of the lining carrier plate, which is received in a bore 38 of the second tab 37.
