摘要:
A clutch pressure plate actuation mechanism includes a solenoid and a lever pivotable about a fulcrum positioned between the ends of the lever. The solenoid includes a fixed electromagnet and an armature connected to a first end of the lever. The second end of the lever is movable into contact with a clutch pressure plate. Attraction of the armature by the electromagnet causes pivoting of the lever about the fulcrum and movement of the pressure plate towards an engaged position. In a dual clutch assembly, the solenoid of one clutch is arranged to act through the friction plate of the other clutch.

The invention relates to a switchable friction clutch having a drive wheel (5) driven by a drive motor via a drive belt, wherein a first electromagnetic arrangement (19) is provided for actuating a first friction clutch (21), and a second electromagnetic arrangement (24) is provided for actuating a second friction clutch (23) in order to be able to drive a drive shaft (13) of an auxiliary unit (3) at varying speeds via the drive wheel (5) at a drive rotational speed. According to the invention, to drive the drive shaft (13) at the varying speeds, the belt drive arrangement is disposed between the drive wheel (5) and the drive shaft (13) of the auxiliary unit (3).

Es wird eine Kupplungs- und/oder Bremseinheit mit wenigstens drei relativ zueinander verdrehbaren Bauteilen (10, 12, 13, 14) beschrieben, mit denen jeweils wenigstens eine Lamelle (28, 30, 31, 32, 33, 41, 42, 43, 48) drehfest verbunden ist. Die Lamellen (28, 30, 31, 32, 33, 41, 42, 43, 48) können wahlweise miteinander in reibenden kraftschlüssigen Eingriff gebracht werden. Um einen vereinfachten Aufbau zu ermöglichen, der sich einfach und kostengünstig herstellen lässt, wird vorgeschlagen, dass mit einem ersten Bauteil (14) wenigstens eine erste Lamelle (28, 30, 31, 32, 33) drehfest verbunden ist, welche über wenigstens einen radial äußeren Reibbelag (34, 35) mit wenigstens einer zweiten drehfest mit einem zweiten Bauteil (10) verbundenen Lamelle (41, 42, 43) in reibenden Eingriff gebracht werden kann. Des Weiteren kann die wenigstens eine erste Lamelle (28, 30, 31, 32, 33) über wenigstens einen radial inneren Reibbelag (36) mit wenigstens einer dritten drehfest mit einem dritten Bauteil (12) verbundenen Lamelle (48) in reibenden Eingriff gebracht werden.
摘要:
A torque transfer mechanism having a multi-plate friction clutch connecting a pair of rotary members and a electrohydraulic clutch actuator for controlling engagement of the friction clutch. The clutch actuator includes a hydraulic pump, a hydraulically-actuated rotary operator, and a thrust mechanism. The hydraulic pump draws low pressure fluid from a sump and selectively delivers high pressure fluid to a series of actuation chambers and return chambers defined between coaxially aligned first and second components of the rotary operator. The magnitude of the fluid pressure delivered to the actuation chamber controls angular movement of the second component relative to the first component for energizing the thrust mechanism. The thrust mechanism applies a clutch engagement force on the friction clutch, thereby transferring drive torque from the first rotary member to the second rotary member. An electrohydraulic control system regulates the fluid pressure delivered to the actuation and return chambers.
