摘要:
An elastic return device including a gasket and a clutch mechanism whose actuating system includes a control chamber designed to receive a pressurized fluid, a piston which is axially movable in the control chamber so as to engage or disengage the corresponding clutch, a balancing chamber situated opposite the control chamber in relation to the piston, and an elastic return device housed in the balancing chamber and designed to exert an axial force against the piston. According to the invention, the elastic return device includes, on one of its faces bearing against the piston, an internal peripheral end which extends radially beneath the piston and which carries a gasket in order to seal off the balancing chamber from the control chamber. The invention likewise relates to a transmission system including such a dual clutch mechanism.
摘要:
A friction clutch for coupling a drive shaft of a motor vehicle engine to a transmission input shaft of a motor vehicle transmission. An input disk carrier is couplable to the drive shaft and an output disk carrier is couplable to the transmission input shaft. A return spring positions the output part in a defined initial position relative to the input part. The return spring allows a higher pressing force between the input part and the output part in the engaged state when the friction lining is in a worn condition than when the friction lining is in the non-worn condition. Through the use of the return spring to also transfer torque, a pressing force that reduces as the friction linings become worn can be compensated for by changing the direction of force of the torque introduced through the return spring for reliable engagement of the friction clutch.

Dual clutch including two clutch units acting in a force-fitting manner and mounted on a common clutch hub in a rotationally fixed and axially movable manner, a pressure disk arrangement retained between the clutch units on the clutch hub in an axially fixed manner and including two axially movable pressure pistons each of which can be ventilated by a compression spring arrangement positioned in the clutch hub. Each compression spring arrangement includes multiple compression springs, each of which is arranged in a recess of the clutch hub. Each recess is introduced into the clutch hub as an axially extending blind hole. The pressure disk arrangement is received in a radial groove of the clutch hub, the groove being radially and/or axially spaced from the blind holes.

A torque transmission arrangement for a motor vehicle has a drive element (4) and at least one output element connected to one another via a transmission (6) and a shift clutch arrangement (8). The shift clutch arrangement (8) has an actuator (40) that moves a first clutch element (32) axially in the direction of a second clutch element (34) via a displacement element (42, 44) in such a way that a positive connection can be produced between the drive element (4) and the output element. The first clutch element (32) bears via an axial bearing arrangement (50) against the displacement element (42, 44) as seen in the axial direction. The axial bearing arrangement (50) has a rolling bearing (58) and a bearing disk element (62) directed toward the first clutch element (32).
摘要:
Clutch arrangement for a motor vehicle drive train. The clutch arrangement has a first and a second clutch which are embodied as normally open clutches. The first clutch can be activated from an open position into a closed position by means of a first actuator arrangement. The second clutch can be activated from an open position into a closed position by means of a second actuator arrangement. The clutch arrangement has a locking device for locking a clutch in the closed position. Only the second clutch can be locked in the closed position by means of the locking device, while the first clutch cannot be locked in the closed position. Thus, the first actuator arrangement has to be supplied with energy in order to secure the first clutch in the closed position.

A pressure plate assembly for a friction clutch includes a housing, a pressing plate arranged to rotate with the housing, and a force accumulator arranged to exert an axial force on the pressing plate. A wear take-up element between the accumulator and the pressing plate moves to adjust for wear, and an adjusting member is brought into a take-up starting position when wear occurs and is acted on by centrifugal force in order to carry out an adjusting movement wherein the adjusting member moves out of the take-up starting position. The adjusting member cooperates with the wear take-up element by way of a transmission member which moves with respect to the wear take-up element when the adjusting member is brought into the take-up starting position. During the adjusting movement, the transmission member is acted upon by the adjusting member and moves jointly with the wear take-up element.
摘要:
A lever system for actuating a clutch or a brake for a vehicle, such as a motor vehicle. The actuating force for the clutch or transmission brake is changeable by displacing a fulcrum with respect to a lever. An energy storage mechanism may act at one end portion of the lever and a pressure plate of a clutch or a transmission brake may act, directly or indirectly, on the other end portion.
摘要:
A multi-clutch arrangement, especially a dual clutch for motor vehicles, comprising a first clutch area with a first pressure plate arrangement, with a first opposing support arrangement, and with a first clutch disk arrangement, which can be clamped between the first pressure plate arrangement and the first opposing support arrangement to transmit torque via the first clutch area; and a second clutch area with a second pressure plate arrangement, with a second opposing support arrangement, and with a second clutch disk arrangement, which can be clamped between the second pressure plate arrangement and the second opposing support arrangement to transmit torque via the second clutch area. A torsional vibration damper arrangement is assigned to at least one of the clutch areas, and where—relative to an axis of rotation (A)—the torsional vibration damper arrangement is arranged at least partially in the axial area of the first clutch area and/or of the second clutch area.

A clutch system includes a clutch device with at least one clutch arrangement for installation in a motor vehicle drive train between a drive unit and a transmission. The at least one clutch arrangement is actuated by a slave cylinder using a pressure medium which is supplied to the clutch device by a first pump. A further medium is also supplied to the clutch device by a second pump arrangement as an operating medium used during operation of the clutch device. The further medium is selectively supplied as a pressure medium to the slave cylinder.

In a pressure accumulating hybrid vehicle, a power switching device (5) is interposed between tires (2) of the vehicle and a hydraulic pump/motor (6). The vehicle includes a drive shaft (10) for transmitting a braking torque from tires (2) to the hydraulic pump/motor (6), and a clutch device (11) provided between the drive shaft (10) and a sub-input portion (22) of the power switching device (5). A clutch disc assembly (31) included in the clutch device (11) has an outer diameter three to five times greater than an outer diameter of the drive shaft (10) and a frictional member (40) brought into contact with a frictional surface (30c) of the power transmission member (30)
