A multi-plate dual clutch for coupling a motor vehicle engine to a drive shaft of a motor vehicle transmission and to an auxiliary power take-off output shaft of the motor vehicle. The dual clutch includes a drive clutch for coupling the motor vehicle engine with the drive shaft, and an auxiliary power take-off clutch for coupling the motor vehicle engine with the auxiliary output shaft. The drive clutch and the auxiliary power take-off clutch can each to be operated independently of one another by a separate lever mechanism. The dual clutch includes a wet chamber housing in which the drive clutch, the auxiliary power take-off clutch, and the respective lever mechanisms are accommodated in fluid-tight relationship.

The dual clutch includes a drive clutch for coupling the motor vehicle engine with the drive shaft, and an auxiliary power take-off clutch for coupling the motor vehicle engine with the auxiliary output shaft. The drive clutch and the auxiliary power take-off clutch can each to be operated independently of one another by a separate lever mechanism. The dual clutch includes a wet chamber housing in which the drive clutch and the auxiliary power take-off clutch are accommodated in fluid-tight relationship, while the respective lever mechanisms for the drive clutch and the auxiliary power take-off clutch are located outside the wet chamber housing.

Double clutch for coupling a drive shaft of a motor to a transmission shaft of a transmission in a vehicle having a first friction clutch for frictionally clamping a first clutch disc couplable to the transmission shaft between a first pressure plate and a first counter-plate, the first pressure plate displaceable in an axial direction to close the first friction clutch, a second friction clutch for frictionally clamping a second clutch disc couplable to an accessory power take-off between a second pressure plate and a second counter-plate, the second pressure plate displaceable in the axial direction to close the second friction clutch, a first actuating element configured to displace the first pressure plate, and, a second actuating element configured to engage a pressure ring connected to the second pressure plate to displace the second pressure plate, wherein the second actuating element is pre-loaded by at least one wire load ring.

Double clutch

A dual clutch for coupling an engine drive shaft with a transmission shaft and/or an auxiliary power take-off. A first friction clutch presses a first clutch plate that is couplable with the transmission shaft between a first contact plate, displaceable in an axial direction to engage the first friction clutch and a first counter plate. A second friction clutch presses a second clutch plate that is couplable with the auxiliary power take-off between a second contact plate, displaceable in the axial direction to engage the second friction clutch and a second counter plate. First and second actuating elements move the first and second contact plates; respectively. The second contact plate is connected to a thrust ring connected to the second actuating element to transfer displacing movement. The second actuating element has a spring element, situated between the second actuating element and the thrust ring, for pre-stressing so that a reduction of contact force is avoided in case of wear and tolerance dependency of the contact force and/or actuating force is decreased.

Dual clutch

A friction clutch device, in particular for a drive train of a motor vehicle which is driven by internal, combustion engine, having a rotational axis, a housing, at least one pressure plate which can be displaced in the direction of the rotational axis relative to the housing for an actuation, and a spring device for loading the at least one pressure plate, in which friction clutch device the spring device has a first element for generating a pressure force which acts on the at least one pressure plate, and a second element which is separate structurally from the first element for transmitting an actuating force, in order to improve the friction clutch structurally and/or functionally.

Friction clutch device

A friction clutch, especially a double clutch, with a clutch housing on which at least one actuation lever is pivotally supported. A connecting member in the form of a pressure lever or an eyebolt is coupled with the actuation lever for actuation of a clutch pressure plate. The pressure lever or the eyebolt is formed as a one-piece stamped element to minimize machining and assembly costs.
