A control device of a bicycle hydraulic brake, comprising a cylinder, a tank, a piston slidably mounted in the cylinder to move between at least one first rest position in which the cylinder and the tank are in fluid communication and at least one second position in which the piston interrupts the fluid communication between the cylinder and the tank, a stop device that acts directly or indirectly on the piston. The cylinder and the tank are filled with hydraulic fluid and the stop device can take up a storage and transportation configuration in which it arranges the piston in said at least one second position.

The present invention relates to a coupling arrangement (24) comprising a first part (12), which defines a longitudinal axis (L), a second component (14), which is displaceably mounted along the longitudinal axis (L), a press-on element (16), which pretensions the second component (14) in a first position, in which the second component (14) is in frictional engagement with the first component (12), and an actuating unit (18), with which the second component (14) can be displaced from the first position in a second position, in which the second component (14) is distanced from the first component (12), wherein the actuating unit (18) comprises an actuator (20), which is displaceable along the longitudinal axis (L) and thereby provides an opening force, and a lever (22) which is rotatably mounted in the second component (14) about an axis of rotation (D) that is perpendicular to the longitudinal axis (L), and has a contact surface (26), with which the lever (22) is in contact with a fixed mating surface (28), wherein the contact surface (26) and/or the mating surface (28) has a convex curvature (30), and the actuator (20) and the lever (22) cooperate in such a way that the movement of the actuator (20) along the longitudinal axis (L) is converted into a movement of the lever (22) on the mating surface (28), whereby the second component (14) is displaced along the longitudinal axis (L) in the second position.

A slave device is provided for a clutch system of a motor vehicle, in particular a clutch slave cylinder, in the form of a concentric slave cylinder. The slave device includes a housing element having, in its interior, a pressure chamber and an annular gap arranged on the outside of the housing element wherein the annular gap is in fluid communication with the pressure chamber. A clutch system for a vehicle includes the slave device, clutch apparatus for connecting an input side to an output side, a transmission housing on the output side, and seals of the slave device lying against the transmission housing in the radial direction for sealing the annular gap.

An actuating device for a motor vehicle, including a housing and a multi-part working piston movable in relation to the housing. The multi-part working piston has a main piston and an adjusting piston, which pistons are formed in a manner movable axially with respect to each other to compensate for wear. A clamping device clamps the main piston and the adjusting piston in relation to each other in order to fix an operative length of the working piston. The main piston and the adjusting piston are partial pistons of the working piston. A shielding element for protecting the actuating device from dirt is arranged on the housing and a partial piston or on a first partial piston and a second partial piston or on an adjusting piston and on the clamping device.

A pneumatic clutch actuator is described herein. The pneumatic clutch actuator includes a piston housing and a piston slidably received within the piston housing and configured to selectively change a clutch state between an engaged state and a disengaged state. The piston includes a self-adjustment mechanism that is configured to adjust an axial length of the piston. The self-adjustment mechanism includes a position locking assembly that includes a locking member and a positioning member. The locking member includes a plurality of locking flanges spaced along an outer surface of the locking member. The positioning member includes a plurality of positioning slots that are spaced along the positioning member. The position locking assembly is positionable between an unlocked state with the locking member spaced a distance from the positioning member, and a locked state with at least one locking flange inserted into a corresponding positioning slot.

A release bearing arrangement is provided for a piston of a clutch cylinder of a multi-plate clutch, which piston is axially movable along a shaft of a motor vehicle. The release bearing arrangement includes a release bearing for axial force transmission of an actuating force introduced by the piston to a transmission device of the multi-plate clutch. The release bearing has a first bearing plate, a second bearing plate and a plurality of rolling elements, the rolling elements being arranged so as to roll between the first bearing plate and the second bearing plate. The release bearing arrangement has a self-centering device for radial self-centering of the release bearing relative to the shaft and/or relative to the piston that is axially movable along the shaft.

A clutch device for a gearbox of a utility vehicle, including: a clutch actuator; a sensor for detecting a position of the clutch actuator; and a sensor stop having a stop surface, which defines a predetermined position of the sensor in a distance direction to the clutch actuator; in which the sensor is holdable via an elastic element in a distance direction in a positionally fixed relationship with the sensor stop.

The clutch pedal system for a vehicle, such as a motor vehicle, is disclosed. The clutch pedal system includes a pedal carrier having a fastening region configured to be associated with an aperture in a bulkhead and/or a dashboard carrier of the vehicle. A clutch pedal is pivotably mounted on the pedal carrier. A master cylinder is supported on an adapter region of the pedal carrier and is connected to the clutch pedal. The master cylinder is positioned such that at least a portion of the master cylinder extends through the aperture, wherein the pedal carrier is configured to position the master cylinder in a predetermined position relative to the bulkhead and/or of the dashboard carrier.

An actuating apparatus has a first and a second actuating element that delimit a pressure chamber. The actuating apparatus has a rotary decoupling bearing coupled via a compensation assembly to the second actuating element for joint movement along the spatial axis. The compensation assembly comprises a first ramp element which is supported axially on the second actuating element and is preloaded relative to the second actuating element by a first preloading apparatus for rotation about the spatial axis and a second ramp element coupled to the rotary decoupling bearing. An axial overall length of the compensation group along the spatial axis changes in the case of a rotation, of the first ramp element relative to the second actuating element. The compensation assembly has a blocking element and a blocking toothing system in blocking engagement with a counter-blocking toothing system of the first ramp element
