Abstract: A torsional vibration damper for a clutch disk within a drive train of a motor vehicle includes an input part arranged around an axis of rotation (d), a spring device with at least three spring elements, an output part, and torque-transmitting intermediate elements. The output part can be rotated relative to the input part about the axis of rotation (d) to a limited extent against the spring device. The torque-transmitting intermediate elements are arranged between the input part and the output part for forcible radial displacement by means of cam mechanisms when the input part rotates relative to the output part. The spring device is arranged between the torque-transmitting intermediate elements, and a number of intermediate elements corresponds to a number of spring elements.

Abstract: A clutch disc includes an input part, an output part, and a vibration damper. The vibration damper includes a first part with a first flange area, a second part with a second flange area, a spring device, and first and second intermediate parts. The intermediate parts are coupled to the first flange area and the second flange area by respective slide devices such that movement of the intermediate parts relative one another is inhibited by the spring device. The flange areas are each in operative connection with the input part and the output part such that a load acting on the input part that changes from either rotational direction to an opposite rotational direction moves the first flange area relative to the second flange area in a single fixed direction of movement.

Abstract: An adjustment device (1) for a friction clutch (2), including at least the following components: a rotatable driving device (3); an adjustment spindle (4) having an axial direction, which is connected to the driving device in a rotationally fixed manner; a spindle nut (6), which is moved in the axial direction by rotation of the adjustment spindle; and an adjusting unit (7) for adjusting a distance (8) between an engagement device (9) and a pressure plate (10), which adjusting unit is adjusted by an axial motion of the spindle nut (6) in such a way that the axial direction (5) of the adjustment spindle (4) can be oriented parallel to a radial direction (11) of the friction clutch (2). Through the adjustment device here, it is possible to realize a robust functional unit that is sufficiently stiff with respect to the applied centrifugal forces and that has low production requirements, low weight, and low installation space.

Abstract: A readjustment device for travel-controlled wear readjustment for a friction clutch includes a spindle with a spindle nut for rotating a pressure plate relative to a counter plate via a ramp system having a ramp ring for axial displacement of the pressure plate relative to the counter plate as a function of a relative rotation. The ramp ring has a first engagement device that is connected in a positively locking manner to the spindle nut. The first engagement device is designed such that, in an assembled state, the first engagement device is detachably connected to the spindle nut. This allows an inspection of the function of the readjustment device, in particular of the ramp system, in an assembled state of the readjustment device to be performed with little expenditure of time and without the risk of damage to a component, for example to the blocking elements on the pinion.

Abstract: A clutch assembly in which a clutch, in order to engage, is pressed together against the force of the lining springiness via a lever plate. An additional spring force, which acts upon the lever plate in an opposite direction, alters the load placed on the clutch actuator whereby enabling it to be adapted to a linear compensating spring in an advantageous manner. The additional spring force is preferably applied by a disc spring, whereby the lever plate itself can be provided in the form of a lever disc spring. On the clutch actuator, a change in the direction of force can be prevented when the spring forces are appropriately matched.

Abstract: A method for assembling a clutch system on a drivetrain is proposed in which the clutch system is mounted on the transmission and in which the transmission is then connected to the engine block.

Abstract: A power transmission for a motor vehicle. The transmission includes a plurality of transmission ratio steps defined by pairs of gear carried on parallel shafts, and final output mechanisms for engaging desired transmission ratio steps. The final output mechanisms are operable for controlling the engagement of respective transmission ratio steps to minimize tractive force interruption by allowing rapid gear changes to be effected to reduce the times between shifts of gears. By sensing accelerator pedal position and vehicle speed a new transmission ratio step to be subsequently engaged can be pre-selected while an engaged gear remains engaged.

The clutch includes at least a pressure plate, a clutch disk, and a flywheel, by way of which a torque is transmitted. The friction forces that exist on the respective friction surfaces of the clutch disk are unevenly distributed. The clutch is cooled by a flow of cooling air that is led through the clutch bell that encloses the clutch and that defines a housing. The cooling air is conducted from the existing ventilation air inlets of the vehicle, and a jet pump arranged in the exhaust system is disclosed for withdrawing the cooling air from the clutch housing.
