Definitions
- the invention relates to a brake carrier for a partial brake disc brake according to the preamble of claim 1.
- Brake carriers for such partial brake disc brakes are usually either integrated into the steering knuckle of a motor vehicle or fastened to it.
- a brake housing, which surrounds the edge of the brake disk and on both sides of the brake disk, is axially displaceably mounted on the brake carrier.
- Generic brake carriers are known in a variety of embodiments.
- DE 44 31 724 AI discloses a disc brake which has a brake carrier which has axially protruding brake support arms.
- guide sections are provided on the brake support arms, on which the two brake pads are supported and guided in an axially displaceable manner.
- the brake pads with lateral support parts in the circumferential direction engage in a form-fitting manner in the guide sections of the brake support arms in such a way that the friction forces absorbed by the brake pads are transmitted to both brake support arms at least with higher brake system forces.
- there is a not inconsiderable elastic deformation of the brake support arms in the circumferential direction which has a particularly strong effect due to the lever arms at the axially outer end of the brake support arms.
- the resulting misalignment of the brake arms in the circumferential direction also affects the housing via the brake pads and thus leads to an undesired misalignment of the brake housing and the two brake pads.
- the invention has therefore set itself the task of preventing or reducing the misalignment of the brake housing, in particular of the brake support arms, by measures on the brake carrier.
- the solution to the object is achieved by the combination of features of claim 1.
- the elasticity of the brake support-side lining support of the inner brake lining is increased by the material rigidity of the brake support arm in the U direction of the axially inner lining support is specifically reduced.
- the housing misalignment has been reduced considerably.
- the brake linings are supported in a form-fitting manner on the brake support arms in the circumferential direction in such a way that the frictional force occurring in the circumferential direction on the brake linings is transmitted to both brake support arms at least with higher brake application forces.
- a brake carrier with pull-push support of the brake pads can be specifically designed with a suitable choice of the tolerance field for brake pads and pad supports such that a noise-resistant pull design of the brake pads is selected for small brake application forces, while with high braking forces due to the elasticity the pad supports a push-pull support for both brake pads can be guaranteed.
- the axially inner lining support is formed on an essentially axially extending web which is connected in one piece to the brake carrier arm.
- An essentially axially extending recess remains between this web and the brake carrier arm, as a result of which the web with lining support is elastically flexible in the circumferential direction.
- the same flexibility in the circumferential direction under load can be set for the inner as for the outer lining support.
- Such measures on brake carriers can extend both to a single brake carrier arm (push or pull support) and to both brake carrier arms (push-pull support).
- the measures on the brake carrier are carried out directly when the brake carrier blank is cast, the essential dimensions of the brake carrier being able to be retained in comparison with known designs.
- At least one guide pin for axially displaceable mounting of the brake housing is attached directly to the inner lining support, which is elastically flexible in the circumferential direction.
- the guide pins follow the deformation of the brake support arms or, in particular, the deformation in the region of the axially inner lining support, by parallel displacement in the circumferential direction, and thus prevent the brake housing from being skewed.
- 1 is a three-dimensional rear view of a brake carrier with circumferentially elastic pad support of the inner brake pad
- FIG. 2 shows a three-dimensional top view of the brake carrier from FIG. 1.
- a brake pad brake consists essentially of a base section 2 which extends in a secant direction of the brake disk (not shown) and two brake support arms 3 which adjoin the lateral ends of the base section 2 and which in the axial direction have the outer edge protrude from a brake disc, not shown.
- the base section 2 can be screwed through two through holes 4, in particular on the steering knuckle of a motor vehicle.
- the spaced-apart parallel brake support arms 3 are integrally connected to the base section 2 and are used for axially displaceable guidance and support of brake pads, not shown.
- axial guide grooves 5 are formed in the brake support arms 3, which are open to the outside in the radial direction.
- the brake pads engage with hook-shaped, lateral support parts in the guide grooves 5 and thus allow the frictional force occurring on the brake pads in the circumferential direction to be transmitted to both brake support arms 3.
- this is realized by means of support surfaces 6 oriented perpendicular to the circumferential direction within the guide grooves 5.
- the support surfaces 6 facing or facing away from the brake center, together with correspondingly oriented contact surfaces on the non- brake pads showed a pulling (Pull) and / or pushing (Push) support of the two brake pads.
- the pad support 7 for the axially outer brake pad is subject to a certain elasticity anyway due to the lever arms of the brake carrier arm 3.
- the axially inner pad support 8 is formed on a substantially axially extending web 9.
- the web 9 is connected in one piece to the brake carrier arm 3 and has an elastic flexibility in the radial as well as in the tangential direction when loaded. In the circumferential direction, an axially extending recess 10 remains between the web 9 and the brake carrier arm 3.
- the inner lining support 8 in the brake carrier 1 from FIG. 1 can be deformed elastically in the circumferential direction considerably more easily.
- the inevitable deformation, in particular of the brake support arms 3 in known brake support designs, was manifested in particular in an inclined position of the brake support arms 3 in Direction of rotation of the brake disc.
- Such an inclination has a very strong effect on the axially outer lining supports 7 in the form of a tangential displacement.
- the elastic resilience in the circumferential direction of the inner lining support 8 can be adapted to that of the outer lining support 7 by targeted constructive design of the web 9 and the recess 10.
- undesired oblique wear on the brake linings and a resulting stronger tendency to brake noises for a wide variety of brake types with generic brake carriers can be avoided.
- the deliberate push-pull design of both brake linings can be facilitated in the case of partial brake pads of this type of brake.
- Another advantage results from arranging the guide bolts (not shown) attached to the brake carrier 1 in the immediate vicinity of the inner lining support 8, which is elastic in the circumferential direction, on the brake carrier 1.
- two guide bolts are screwed into threaded bores 11 of fastening eyes 12 on the base section 2.
- the spaced axially oriented guide pins are axially displaceable within bores of the brake housing, not shown.
- the arrangement of the fastening eyes 12 for the guide bolts directly on the inner lining support 8 results in a considerable reduction in the misalignment of the brake housing when high braking peripheral forces are absorbed by the brake carrier 1.
- the design of the web 9 or the recess 10 is formed directly in the configuration of the brake carrier blank 1 produced by casting. This avoids additional machining operations. At first, nothing is changed in the basic dimensions of the brake carrier 1 by the design measures according to the invention. The existing processing steps on the cast blank can be maintained using existing tools or machines.
- the configuration of the elastic support which is the same in the circumferential direction, for the inner as well as the outer brake lining is of course not limited to the exemplary embodiment shown in the figures.
- the reduction in the material stiffness of the inner lining support 8 can, depending on the type of lining support selected, also be achieved exclusively on the inlet and outlet side brake support arm 3. This means that the principle can be implemented for any type of base support.
