The present invention relates to a brake actuating mechanism for a disc brake having an optimized adjusting device.

Disk brake

The present invention concerns a brake actuation mechanism for a disc brake, in which a translational movement in the direction of the brake disc leads to a rotation of an input element of an adjustment device, the input element of the adjustment device being designed as part of a ball screw drive. Furthermore, the invention concerns a disc brake with such a brake actuation mechanism.

Disk brake and brake actuation mechanism

A brake including an adjustable thrust element for applying a brake force to a brake pad and an adjustment device for selectably adjusting the thrust element. The adjustment device includes a shaft having a cylindrical shaft surface, a sleeve having a cylindrical sleeve surface, wherein the shaft and the sleeve are arranged end-to-end, and a torque clutch including a wrap spring that is mounted on the cylindrical shaft surface and mounted on the cylindrical sleeve surface, the shaft including an integral drive pin for selectively rotating the shaft. The brake further includes an operating lever, wherein the drive pin extends radially directly from the shaft surface of the shaft and wherein the operating lever includes a groove that receives the drive pin.

Disk brake and production method for a disk brake

The present invention refers to a disc brake having a brake caliper, which overlaps at least one brake disc, and a brake actuation mechanism having an amplification mechanism including a brake lever being rotatable around a pivot bearing for introducing a clamping force from an actuator, the brake lever having an arm extending between its actuator connection means and its transmission means, a thrust element in connection with said transmission means for transmitting the amplified clamping force onto the brake disc, in which the brake lever comprises a recess between its actuator connection means and its transmission means, which recess is traversed by the axis of said pivot bearing.

Disk brake and method for manufacturing the same

A disk brake having a brake caliper and a brake actuation mechanism being supported in it, in which the brake actuation mechanism includes an amplification mechanism for introducing a clamping force, an adjustment device for compensation of lining wear with a torque clutch, a thrust element for transmitting the clamping force onto a brake disc and a reset device, which components are arranged around a rod, in which the torque clutch, for example, is formed as a roller-ramp-mechanism. A spring force can act onto the torque clutch by means of the reset device thereby forming a torque limit. Furthermore the invention relates to an assembly method for such a disc brake.

A disc brake including a brake actuation mechanism and an adjustment mechanism, which is configured to provide, in addition to a reduction of the clearance between a brake pad and a brake disc during brake application, a further increase of the clearance during brake release motion with a value, which may be smaller, equal or larger than the previous clearance reduction. The brake actuation mechanism for that purpose could provide a different regulator unit. Moreover, the invention suggests a method for adjusting the clearance between a brake pad and a brake disc providing a clearance increase during brake release motion, accordingly.

Disc brake, brake actuation mechanism for such a disc brake and method for brake adjustment

A disc brake including a brake caliper and a brake actuation mechanism having an amplification mechanism for introducing a clamping force, an adjustment mechanism for compensating a lining wear having a torque clutch, a thrust element for transmitting the clamping force onto the brake disc, wherein the thrust element includes an adjustment spindle, and a return mechanism, wherein the amplification mechanism, the adjustment mechanism, the thrust element and the return mechanism are mounted in a functional interacting manner in the brake caliper by way of a rod. The disc brake is further provided with at least one device, which is configured to exert a defined resistant torque on the rotation of the adjustment spindle.

A brake actuation mechanism for a disc brake including an amplification mechanism, an adjustment mechanism, a thrust element and a return mechanism, which are mountable inside a caliper housing by way of a rod so as to be functionally interacting, in which the adjustment mechanism includes a torque limiting clutch mechanism drivingly connecting several elements and including a first clutch element drivingly connecting a rotatable input element with a rotatable output element and a second clutch element connecting the rotatable output element with the rod, the rotatable output element radially surrounding the first clutch element and the second clutch element. A disc brake including such brake actuation mechanism is also contemplated.

The present invention relates to a disc brake having a housing, a clamping device, a push rod, and a self-activating adjustment device, whereby the adjustment device includes a first subassembly and a second subassembly. According to the invention the adjustment device includes an assembling joint, which makes possible the transmission of a rotary motion from the first subassembly to the second subassembly, whereby the assembling joint allows an axial relative motion between the first subassembly and the second subassembly, whereby the assembling joint permits an axial relative motion between the first subassembly and the second subassembly of the adjustment device. According to a particular embodiment of the invention, a misalignment of the push rod inside a place, which lies parallel to the brake disc, can occur with respect to the housing, without resulting in jamming of the cylindrical element with respect to the push rod and housing.

Disk brake with adjustment device

The invention relates to a brake gear for a disc brake serving to transfer a force to a brake pad that acts upon a brake disc. The brake gear is accommodated in a brake caliper of the disc brake and comprises both a pressing element, which interacts with the brake caliper, as well as a rod. The pressing element is mounted in the housing of the brake caliper with the aid of the rod in such a manner that it is parallel to the rotation axis of the brake disc.

Brake gear for a disc brake

The present invention concerns a connection between at least one brake disc and a hub or the like of a disc brake. The brake disc(s) is received slidable and non-rotatable on the hub. Each brake disc is furnished with plates on an inner periphery, which plates have a length in the axial direction of the hub exceeding the thickness of the brake disc.

Compact disc support

The present invention concerns a brake mechanism of a disc brake received in a caliper and a method for controlling the force amplification for the brake mechanism. The brake mechanism comprises a lever actuated by a brake actuator. The lever is acting on a cross bar by means of an intermediate part. The lever and the intermediate part have a line of contact moving along a circular arc during an application stroke of the brake mechanism. The cross bar of the brake mechanism is closely guided and is only moveable in the thrust direction and in the tangential direction of the brake disc. The force amplification of the brake mechanism is adapted to the force characteristics of the brake actuator.
