Description

The invention relates to a wheel brake arrangement for a motor vehicle having the features of the preamble of claim 1, having at least one wheel carrier which can be suspended from a vehicle body and at least one brake caliper arranged on the wheel carrier, with at least one nose being formed on the brake caliper and at least one recess being formed on the wheel carrier , wherein the lug engages in the recess with play in such a way that the brake caliper is pivotably connected to the wheel carrier about a pivot axis arranged parallel and spaced apart from a wheel axis of rotation defined by the wheel carrier.

A generic wheel brake is in the U.S.A. 4,467,898 discloses a disc brake having a brake caliper slidably attached to a fixed support via an axial post protruding from the fixed support. Upon axial movement of the caliper with respect to the fixed support beyond a predetermined distance, the sliding surfaces can be disengaged, allowing the caliper to pivot about the post so that the friction elements can be replaced. The movement of the caliper relative to the fixed support is normally constrained to a distance less than the predetermined distance by a stop pin carried by the caliper.

the DE 10 2006 057 938 A1 relates to an arrangement with a particular electromechanical disc brake, which can have self-boosting. In this case, it is proposed to fasten a brake caliper of the disc brake to a brake holder by means of joints and via a coupler. The coupling compensates for manufacturing and assembly tolerances as well as different temperature expansions. The attachment of the brake caliper is statically determined. By opening one or both joints of the brake caliper, it can be swiveled outwards or removed to change the friction brake linings.

A limb unit according to U.S. 2016 0 169 324 A1 includes two first link plates and a mounting pin. Each of the first link plates has a first inner end portion, a first outer end portion offset from the first inner end portion, and opposing inner and outer side surfaces. The first outer end portion of each of the first link plates is formed with a connecting hole having a first hole portion, a second hole portion, and a neck portion located between the first and second hole portions. The mounting pin is inserted through the connecting hole of each of the first link plates and is prevented from moving past the neck portions of the first link plates to be positioned in the second hole portions of the first link plates.

the EP 0 099 781 A2 discloses a sliding and elastic locking element for a floating disc brake carried by a single axial support, also disclosing a disc brake equipped with such an element.

Motor vehicles have a wheel brake per wheel, which can be designed as a disc brake. A disk brake has a brake disk connected in a torque-proof manner to a wheel hub and a brake caliper connected to a wheel carrier. The brake caliper is usually fastened to the wheel carrier via two connecting means, in particular screw connections. The connecting means transfer at least part of the respective braking force to the wheel carrier. This rigid coupling of the brake caliper to the wheel carrier causes unwanted transmission of vibrations from the wheel brake to the wheel carrier during a braking process, from where the vibrations are transmitted to a wheel suspension hanging the wheel carrier on a vehicle body of the motor vehicle and finally to the vehicle body. This degrades the NVH behavior of the motor vehicle.

the CA2 170 168 A1 discloses a braking system having a ring braking element and a suspended caliper with a responsive linkage correcting the caliper and a knuckle support assembly. The ring brake element is preferably die cast as a single component with a control hub and is made from a lightweight and high strength, high temperature aluminum composite material. The braking system is designed to have a relatively thick ring brake element made from this lightweight material to provide sufficient ability to absorb braking heat and transfer that heat to the surrounding air before the ring brake reaches a temperature at which damage occurs. Normal operating temperature is well below the theoretical maximum or rated temperature of the composite material.

the DE 10 2011 108 301 A1 relates to a fastening arrangement of a brake caliper on a steering knuckle or wheel carrier with a single fastening element which is arranged between the steering knuckle/wheel carrier and the brake caliper, and at least one additional means which is also between the steering knuckle/wheel carrier Wheel carrier and the brake caliper is arranged. The at least one additional means has a wedge-shaped nose arranged on the brake caliper or on the steering knuckle/wheel carrier, which engages in an associated abutment arranged on the steering knuckle/wheel carrier or on the brake caliper and is clamped there.

the JP 5 198 237 B2 discloses a vehicle suspension device for coupling a brake caliper to a wheel carrier for rotatably supporting a wheel hub rotated integrally with a brake rotor. The wheel carrier is connected to an upper arm and a lower arm via bushings, respectively. The wheel carrier and the brake caliper are coupled via two sections of coupling sections. One of the two portions of the coupling portions is not coupled via an elastic member, and the other is coupled via an elastic member.

the KR 10 2007 0023388 A discloses a fastening of a brake caliper to a wheel carrier by means of fastening screws, which are each arranged so as to be axially movable on the wheel carrier.

the KR 10 2003 0087156 A discloses an apparatus for reducing vibration when braking a vehicle having a wheel carrier, a brake disc combined with the wheel carrier to rotate together with wheels, a brake caliper assembly attached to the wheel carrier to mate with a pair of brake pads to bring the brake disc into contact with the depressing movement of a brake pedal, and bolts to fix the brake caliper assembly to the knuckle. A fulcrum is formed on the knuckle, into which a bolt is inserted. Elastic elements are placed on the sides of the bolt inserted in the pivot.

The publication, which can be accessed via the link http://www.tomorrowstechnican.com/brake-shims-how-to-controlbrake-noise/, discloses a reduction in brake noise using shims.

The object of the invention is to provide a weight-reduced wheel brake arrangement for a motor vehicle, with which a transmission of vibrations from the brake caliper to the wheel carrier of the wheel brake arrangement can be avoided during a braking process, or at least reduced as far as possible.

According to the invention, the object is achieved by a wheel brake assembly having the features of claim 1. The wheel brake assembly has at least one coupling element, which is connected to the wheel carrier pivotable about a first axis parallel to and spaced from the pivot axis and to the brake caliper either rigidly or pivotable about a second axis parallel to and spaced from the pivot axis.

It should be pointed out that the features and measures listed individually in the following description can be combined with one another in any technically meaningful way and show further refinements of the invention. The description additionally characterizes and specifies the invention, in particular in connection with the figures.

The brake caliper is connected, preferably exclusively, via the nose on the brake caliper inserted into the recess on the wheel carrier and via the coupling element to the wheel carrier. Therefore, no conventional connecting means, such as screw connections, are required to attach the brake caliper to the wheel carrier. Compared to conventional wheel brake arrangements, this is accompanied by a reduction in weight and costs. The coupling of the brake caliper to the wheel carrier via the nose-recess connection can also serve to absorb bending loads and vibrations acting on the brake caliper.

During a braking process, the coupling element is loaded with a tensile force in its longitudinal direction. The pivoting of the rotatably mounted brake caliper about the first axis during the braking process is prevented by the radial locking effected by the engagement of the lug on the brake caliper in the recess on the wheel carrier.

The coupling element is designed and connected to the brake caliper and the wheel carrier such that loads can be transferred from the brake caliper to the wheel carrier and vice versa along a connection direction defined by the respective position of the coupling element. On the other hand, the coupling element can be designed and connected to the brake caliper and the wheel carrier such that the brake caliper can be moved relative to the wheel carrier in a plane of movement transverse to the wheel axis of rotation defined by the wheel carrier. As a result, vibrations that are in the plane of movement and are generated, for example, by brake judder or the like are not transmitted to the wheel carrier. The brake caliper is decoupled from the wheel carrier by a certain extent with respect to the plane of movement by means of the coupling element. As a result, the NVH behavior of the motor vehicle can be improved.

The coupling element is preferably rigid. The coupling element can in particular be made of a metal or a metal alloy. The coupling element is pivotably connected to the wheel carrier via a first joint. The coupling element is also connected to the brake caliper either rigidly or pivotably via a second joint. The joint or joints are preferably designed in such a way that the coupling element is connected to the wheel carrier on the one hand only pivotable about the first axis and on the other hand to the wheel carrier pivotable only about the first axis and to the brake caliper only pivotable about the second axis.

The wheel carrier can be suspended from the vehicle body of the motor vehicle via a wheel suspension, which can have a conventional design. The recess formed on the wheel carrier forms an abutment for the nose.

The brake caliper can be designed, for example, as a fixed caliper, a floating caliper or a pendulum caliper. It makes sense for the brake pads to be supported by the brake caliper, so that the power flow runs from the disc via the brake pads to the brake caliper and from there via the coupling element or a hinge joint to the brake anchor (wheel carrier). As a result, there is no need to screw the brake caliper or a separate brake pad carrier to the brake anchor, which would otherwise be the case.

The nose formed on the brake caliper is preferably connected monolithically or in one piece to the brake caliper. Due to the pivotable mounting of the brake caliper on the wheel carrier, the brake caliper can move relative to the wheel carrier in the plane of movement arranged transversely to the wheel axis of rotation defined by the wheel carrier, so that vibrations in this plane of movement are largely not transmitted to the wheel carrier. The pivotability of the brake caliper relative to the wheel carrier in said plane of movement is made possible by the fact that the lug engages in the recess with play.

According to an advantageous embodiment, the lug and the coupling element are arranged on opposite sides of the brake caliper. This goes hand in hand with a compact design of the brake caliper and thus of the wheel brake arrangement. The two opposite sides of the brake caliper are preferably arranged one behind the other with respect to a vehicle longitudinal direction.

A further advantageous embodiment provides that the coupling element is designed as a roller chain link or monolithically on the brake caliper. In the case of the design as a roller chain link, a known component can be used for the coupling element, as a result of which the wheel brake arrangement can be produced inexpensively. Instead of being a roller chain link, the coupling element can be bone-shaped and monolithic and have enlarged connecting sections at the ends and a smaller central section connecting the connecting sections to one another. Each connecting section can have a through bore, through which a bolt is passed, which is mounted at the end on the wheel carrier or the brake caliper.

According to a further advantageous embodiment, the wheel carrier has at least one first radial projection and at least one spaced apart from the first radial projection arranged second radial projection, wherein the recess is formed on a side of the first radial projection facing the second radial projection and the coupling element with a Portion of the second radial projection is connected, which is located further away from the wheel axis of rotation than the recess. The second radial projection can, for example, be correspondingly longer than the first radial projection. Each projection runs at least essentially in the radial direction, the projections also being referred to as radial projections when the projections run parallel and spaced apart from one another.

According to a further advantageous embodiment, the first radial projection has at least one component which is pivotably arranged between a functional position which at least partially defines the recess and a release position which dissolves the recess. The component can, for example, be pivoted from its functional position into its release position in order to exchange brake pads arranged on the brake caliper. The brake caliper can then be pivoted around the first axis, making the brake pads more accessible, which simplifies assembly work.

According to a further advantageous embodiment, the second radial projection has at least one limiting element, which can be brought into contact with the coupling element, for limiting the pivotability of the coupling element about the first axis. This is particularly advantageous if the coupling element is additionally pivotably connected to the brake caliper via the second axis. When the braking direction is reversed, the limiting element can be used to prevent the coupling element, which is now subject to pressure, from swinging out radially on its own.

According to a further advantageous embodiment, a given radial distance relative to the wheel axis of rotation between a side of the brake caliper facing the wheel carrier and arranged radially on the inside and a side of the wheel carrier facing the brake caliper, arranged radially on the outside and between the radial projections, increases at least partially in the unloaded state of the wheel brake assembly from the first radial projection toward the second radial projection. As a result, the brake caliper can also be pivoted in the direction of the wheel carrier about the pivot axis defined by the nose-recess connection. The side of the brake caliper that faces the wheel carrier and is arranged radially on the inside can be configured and arranged inclined relative to the side of the wheel carrier that faces the brake caliper and is arranged radially on the outside. Alternatively or additionally, the side of the wheel carrier that faces the brake caliper and is arranged radially on the outside can be configured and arranged inclined relative to the side of the brake caliper that faces the wheel carrier and is arranged radially on the inside.

According to the invention, the brake caliper has at least two spaced-apart holding legs for holding at least one brake pad and at least one web connecting the two holding legs, the coupling element is connected to the web and the lug is formed on one of the holding legs. By connecting the web of the brake caliper to the wheel carrier via the coupling element, tilting of the brake caliper can be largely prevented during pivoting of the brake caliper about the pivot axis defined by the nose-recess connection. The lug is preferably formed on the leg of the brake caliper which faces away from a wheel arranged on a wheel hub of the wheel brake arrangement which is rotatably mounted on the wheel carrier.

According to a further advantageous embodiment, the lug is arranged on a front end section of the brake caliper and the coupling element is connected to a rear end section of the brake caliper. This is advantageous since the forces acting on the wheel brake assembly during a braking process are usually significantly greater when driving forward than when driving backwards.

The above object is also achieved by a motor vehicle having the features of claim 9, which has at least one wheel brake assembly according to one of the configurations mentioned above or a combination of at least two of these configurations with one another.

The advantages mentioned above in relation to the wheel brake arrangement are correspondingly associated with the motor vehicle. The motor vehicle can also have its own wheel brake arrangement for each wheel.
