摘要:
A centrifugal clutch includes a housing which is rotatable about an axis, the housing having a plurality of first supporting areas which each extend radially with respect to the axis; a pressing plate which is axially movable with respect to the housing and is coupled to the housing for rotation about the axis; and a supporting element which is axially movable with respect to the housing, the supporting element having a plurality of second supporting areas which each extend radially with respect to the axis, each second support area being separated from a respective first support area by an axial distance which decreases with radial distance from the axis. A plurality of centrifugal members are supported between respective pairs of first and second support areas, each the centrifugal member being radially displaceable by centrifugal force along the respective pair of support areas to exert force along a force transmission path between the supporting element and the pressing plate. An energy accumulator arrangement acts between the supporting element and the pressing plate to load the pressing plate away from the supporting element in a clutch engaging direction, and a clutch release arrangement provides a releasing force in opposition to the load of the energy accumulator arrangement.

Each clutch disk has a hub area designed to be connected nonrotatably to a power takeoff element and a friction surface area designed to be clamped between opposing friction surfaces. Each clutch disk has a torsional vibration damper arrangement including two cover disk elements connected to the hub area for rotation in common, and a central disk element connected to the friction surface area for rotation in common. The central disk element is or can be brought into torque-transmitting connection with the cover disk elements via a damper element arrangement. The central disk element has a damper element interaction area and, radially outside the damper element interaction area, a friction surface carrier area, which is offset with respect to the damper element interaction area in the direction of an axis of rotation.

A pressure plate assembly for a friction clutch including a housing having an axis of rotation; a pressure plate mounted in the housing with freedom to move axially relative to the housing; a stored-energy element mounted in the housing and transmitting force along a path from the housing to the pressure plate; a wear-compensating device in the path of force transmission, which device has at least one adjusting element free to move in an adjusting direction to compensate for wear; and a clearance-producing arrangement having at least one gripping element, which is attached to the assembly upon which the stored-energy element acts via the wear-compensating device. The minimum of one gripping element has a blocking section, by means of which it can make blocking contact with a blocking element when wear occurs. The clearance-producing arrangement also includes an arresting element which can be shifted in an arresting direction when the gripping element comes into contact with the blocking element, thereby arresting the gripping element in the shifted position correlating with the amount of wear which has occurred. A transport-securing device prevents moving the adjusting element in the adjusting direction and/or moving the arresting element in the arresting direction prior to attaching the housing to the centrifugal mass.

A thrust plate assembly having a housing which can be fastened to a flywheel for common rotation about an axis of rotation. A pressure plate is axially displaceable in the housing and is fixed with respect to rotation relative to the housing and is pressed in the direction of the flywheel by an energy accumulator. A wear adjustment device, with at least one adjustment element which is pretensioned in a wear adjustment direction, is arranged in the support path of the energy accumulator. Further, at least one play sensor arrangement is provided for detecting wear occurring during operation. The at least one play sensor arrangement has a locking element with a counter-engagement formation engaging with the engagement formation at the at least one adjustment element. Further, the locking element has a locking engagement formation which engages or is engageable in a detachable manner with a counter-locking engagement formation, the latter preferably being stationary with respect to the pressure plate. The locking element can be moved by a wear detection element and, in this way, the engagement between the locking engagement formation and the counter-locking engagement formation can be canceled.

A friction clutch, especially for motor vehicles, includes a housing connectable with respect to rotation to a flywheel of an internal combustion engine. A pressure plate is arranged in the housing and is urged by a spring toward the flywheel. A clutch disk with friction facings is arranged between the pressure plate and the flywheel such that the spring presses the friction facings ot the clutch disk against the flywheel. A compensation device with at least one element which is changeable along its axial dimension compensates for the change in position of the pressure plate caused by wear of the friction facings, wherein the contact pressure force of the spring acts on the pressure plate via the compensation device. A play transmitter includes two levers, one arranged on each side of the compensation device. One of the levers penetrates the other lever. The penetrated lever includes a stop element which limits the axial movement of the penetrated lever.
摘要:
A motor vehicle friction clutch with a pressure plate which is fastened with the interposition of a clutch disc with friction linings to a flywheel, and which has a common axis of rotation with the flywheel, comprising an application plate located non-rotationally--but so that it can move axially--in a clutch housing, and an application means to apply the application force, is designed so that the amount of work which must be performed by an application means for the engagement and release of the clutch becomes minimal. For this purpose, the clutch housing is provided with an axial guide for a transmission element located between the application means and the application plate, on which the transmission element, as long as there is a separation between the application plate and the friction linings of the clutch disc during an engagement and release movement, can track the movement of the application plate, while as soon as the application plate comes into contact with the friction linings of the clutch disc, the application plate can be clamped fast by means of a change in the angle initiated at its contact point with the application plate for the transmission of the application force, with the formation of a lever arm between this contact point and the engagement point of the application means on the axial guide.
