A coupling for transmitting torque between two parts has a friction coupling with a chamber including a piston and a rotational member. A pumping and control member is positioned in the chamber and includes at least one shear channel. The pumping and control member is rotatable between two positions such that viscous fluid moves through the channel to load the coupling.

A coupling for transmitting torque between two parts has a friction or viscous coupling. The friction coupling is loaded by a piston and rotational member. A shear channel is formed between faces such that viscous fluid contained in the chamber is moved along the shear channels wherein the piston is loaded as a result of shear forces.

A coupling disk has a varying damping cross section of the circumferential gaps as a function of the angle of rotation of the first annular part relative to the second annular part. Thus, in the circumferential gaps, as a result of the shearing effect of the damping fluid, variable damping occurs as a function of the quasi-static angle of rotation due to torque and as a function of the periodic angle of oscillation due to rotational oscillations between the first annular part and the second annular part.

A coupling for transmitting torque between a driving part and a driven part has a hydraulic displacement system which includes a housing having an internally trochoidal shape and a rotor having an externally trochoidal shape. A displacer having a trochoidal shape is positioned between the housing and the rotor. Chamber regions created between the rotor and displacer and displacer and housing are connected by throttle openings in the displacer. An extra trochoidal tooth is provided on the trochoidal face of the housing casing relative to the displacer and on the displacer relative to the rotor.

A friction coupling assembly includes: an actuator in the form of a ball ramp assembly, a plate package, and a ball bearing. The actuator has two coaxial discs, wherein the faces of the two discs each have ball grooves of increasing depth. Pairs of opposed ball grooves hold balls to axially support the two discs. The plate package is arranged coaxially relative to the discs and has outer plates for fixing to a coupling carrier and inner plates for fixing to a coupling hub. The ball bearing is for axially supporting the at least one rotatingly drivable disc, wherein a first bearing race of the ball bearing is integrally formed with the at least one rotatingly drivable disc.

A motor vehicle hydraulic pump (1) is provided comprising a gerotor rotor set or planetary rotor set and at least two output stages. A first output stage (10) of the hydraulic plump (1) is connected to a lubricant, in particular, a clutch lubricant. A second output stage (11) of the hydraulic pump (1) is connected to at least one clutch (2) of the actuation thereof. The invention also provides a method for actuating at least one clutch which is arranged in the motor vehicle by means of a motor vehicle hydraulic pump, whereby an inter-connection of a volume flow outlet of the first step (10) and the second step (11) of the hydraulic pump (1) takes place according to requirements for actuating the clutch.

The disclosure relates to a hydraulic assembly for actuating a setting unit in a motor vehicle. The hydraulic assembly comprises at least one hydraulic actuating unit which acts on the setting unit, as well as at least one piston pump with a piston which is displaceably positioned in a housing, wherein, when the piston moves, there is built up a hydraulic pressure for loading the actuating unit. There is provided a driveshaft with an axis of rotation and an eccentric, wherein the eccentric acts on the piston of the at least one piston pump and, when the driveshaft rotates, builds up a hydraulic pressure. Furthermore, the disclosure relates to a coupling assembly with an inventive hydraulic assembly.

摘要:
A friction coupling for coupling and uncoupling two parts which are rotatable relative to one another, having a coupling carrier (11) which carries outer plates (31) of a plate package (29) and a coupling hub (12) which carries inner plates (32) of the plate package (29), as well as an axially displaceable piston (25) which is able to load, or remove the load from, the plate package (29) which is axially supported on the coupling carrier (11) or on the coupling hub (12). The piston (25), on one side, delimits an annular-cylindrical chamber (26) which rotates with the coupling carrier (11), and in which there rotates a rotor disc 27 which is connected to the coupling hub (12) and which comprises at least one displacer blade (29). The annular-cylindrical chamber (26) is filled with a magneto-rheological fluid and sealed towards the outside. The piston (25) includes a ferro-magnetic material, and opposite the piston (25), there is arranged a controllable magnetising coil (24) which is able to generate a magnetic flow over the chamber (26) and the piston (25).
