    Abstract: A pneumatic actuator (1) includes a pneumatic piston (4) and a pneumatic body (6) that includes a main body (8) and a guide shaft (10) for guiding the pneumatic piston (4). A pneumatic chamber (14) is defined between the guide shaft (10) and the main body (8). The pneumatic piston (4) is received in the pneumatic chamber (14) and slidably arranged on the guide shaft (10). The main body (8) and the guide shaft (10) are separate elements, wherein the guide shaft (10) is fixed to a fixing portion (16). The main body (8) is made from a first material (M1) and the guide shaft (10) is made from a second material (M2) having a higher wear resistance than the first material (M1). The actuator may be used in a clutch assembly (104) and a commercial vehicle (101).

    Abstract: Concentric clutch slave cylinder assembly having a housing and a connector, the housing having a main axis, a main cylinder, an outer concentric cylinder such that an annular chamber is defined. A tubular piston may be slidably mounted on the main cylinder such that it closes the annular chamber. The housing includes a fluid channel connected to the annular chamber and having an axis perpendicular to the main axis. The connector may be joined to the fluid channel such that the connector and the fluid channel have a common axis, the connector having a connection interface to an external tube, wherein the connector and the housing form a single part.

    Abstract: A central release mechanism, in particular for a hydraulic release system of a clutch system of a motor vehicle, including a central release mechanism housing with an annular central release mechanism piston chamber in which a central release mechanism piston is received axially movably by a hydraulic liquid that can be supplied to the central release mechanism piston chamber. The central release mechanism has at least one central release mechanism piston seal which seals the central release mechanism piston with respect to the central release mechanism piston chamber, and the central release mechanism piston seal is arranged in the central release mechanism housing so as to be axially secured at least on one side by a securing ring, the securing ring being connectable to the central release mechanism housing by means of a bayonet connection.

    Abstract: A hydraulic assembly for an electrically operatable multi-gear axle drive train of a motor vehicle, including first and second clutch devices for actuating at least one gear selection device of the electrically operatable axle drive train and a central release mechanism having a first central release mechanism piston that is movable relative to a central release mechanism housing, rotationally fixed to a drive train housing, in a translational manner, and a second central release mechanism piston that is movable relative to the central release mechanism housing, rotationally fixed to the drive train housing, in a translational manner. The radially outer lateral surface of the central release mechanism housing has a groove into which a shell-like toothing element with an outer toothing is inserted and secured axially and for torque-transmission. The outer toothing engages into corresponding toothing rotationally fixed to the drive train housing.

    Abstract: A hybrid module for a motor vehicle for coupling an internal combustion engine includes a disconnect clutch, an electrical machine, a clutch, a dry space and a wet space, and a seal. The disconnect clutch is for transmitting a first torque from the internal combustion engine to the hybrid module, and disconnecting the hybrid module from the internal combustion engine. The electrical machine is for generating a drive torque and includes a rotor. The clutch is for transmitting a second torque from the electrical machine or the disconnect clutch to a drivetrain. The seal is for sealing off the dry space with respect to the wet space. A one of the disconnect clutch or the clutch is a dry clutch in the dry space and the other of the disconnect clutch or the clutch is a wet clutch in the wet space.

    Abstract: A clutch device includes a main clutch, a pilot clutch, and an inner cage. The main clutch has a friction pack, a pressure device for pressing the friction pack, and a ramp system for moving the pressure device. The pilot clutch is for transmitting torque to the ramp system and can be opened and closed by moving the counter-plate. The pressure device can be moved by the counter-plate. The friction pack is mechanically connected to the inner cage and an outer cage. The ramp system includes a first ramp element arranged on the inner cage, a freewheel, and a second ramp element. The freewheel blocks rotary movement of the first ramp element in a first rotational direction and allows rotary movement in an opposite rotational direction. The first and second ramp elements, and the pilot clutch, are mechanically connected to the inner cage when the pilot clutch is closed.

    Abstract: The present invention provides a modular transmission mechanism for a hybrid power system, and a hybrid power system; the modular transmission mechanism integrates a motor, a rotor support assembly, a clutch, a concentric slave cylinder, and an engine output shaft. On the one hand, the modular transmission mechanism enables an input/output bracket of the clutch to be in drive coupling with the engine output shaft, and the rotor support assembly to be in drive coupling with an input shaft of a transmission; on the other hand, the modular transmission mechanism enables the input/output bracket of the clutch to be in drive coupling with the input shaft of the transmission, and the rotor support assembly to be in drive coupling with the engine output shaft. In this way, the modular transmission mechanism according to the present invention can realize a conversion of the hybrid power system between a P1 architecture and a P2 architecture only by simple adjustment on the structure, thereby reducing the research and development cost and burden consumed by separately developing the P1 architecture and the P2 architecture.
