The present disclosure provides a double clutch assembly and a device for assisting an actuator of the double clutch. The device applies an assistance force to the actuator upon an operation of the actuator. In particular, the double clutch assembly includes first and second actuators which engage or disengage first and second clutches, respectively. The device includes: an elastic member to apply an elastic force; a first transfer portion to transfer the elastic force of the elastic member to the first actuator; and a second transfer portion to transfer the elastic force of the elastic member to the second actuator.

A gear mechanism for motor vehicles includes a double clutch gear mechanism with two part gear mechanisms and a double clutch which transmits torque from the engine optionally to one of the two part gear mechanisms, with a central disk connected to a drive disk, two outer pressure application plates which are also connected to the drive disk and are moveable in the axial direction relative to the central disk, and friction disks arranged between the central disk and the pressure application plates, wherein the friction disks consist of two support carrier disks arranged parallel to each other and moveably in relation to each other, between which leaf-like spring segments are provided. To eliminate vibration problems which can occur on start-up from standstill, on load-change processes and during the gear change, the leaf-like spring segments have different spring characteristic curves with which a multistage spring characteristic is achieved.

A friction clutch for a drive train of a motor vehicle driven by an internal combustion engine. The clutch includes a rotatable shaft, a housing, at least one first clutch plate, at least one second clutch plate that is movable axially to a limited extent relative to the at least one first clutch plate to actuate the clutch. An actuating device that has at least one lever that is pivotally-mounted on one of the clutch plates, and at least one bar one end of which is connected to the lever and an opposite end of which is connected by an articulated connection to a different clutch plate to improve the function of the clutch.

A dual clutch having a flywheel comprising an inner conical surface and an outer conical surface, a first clutch comprising a first contact member that is axially movable along an axis relative to first and second transmission-side input shafts for engaging a first conical clutch disc connected to a first input shaft with the inner conical surface of the flywheel, a second clutch comprising a second contact member that is axially movable along the axis relative to the first and second transmission-side input shafts for engaging a second conical clutch disk connected to a second input shaft with the outer conical surface of the flywheel, a mounting means connected to a clutch housing of the dual clutch or to a transmission housing of a motor vehicle transmission, and, actuation means for moving the first clutch and/or the second clutch along the axis.

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.
