Disengaging device for operating clutch, especially in motor vehicle drive train, has arrangement for applying additional load moment to bearing block drive spindle if block movement exceeds threshold

摘要

The device has a lever (7) supported on an ejection bearing by an inner bearing (C) and rotatably on a housing or spring (9) by an outer bearing (A) and a bearing block (15) between the bearings radially movable by a motor-driven spindle (18) with a stop limiting its movement. It has an arrangement for applying an additional load moment to the spindle if the bearing block movement exceeds a threshold. An independent claim is also included for a method of limiting the impact of the disengagement device.
