Abstract
In a drive unit for a motor vehicle a brake is provided for braking down the r.p.m. of the input shaft interconnecting the clutch with the gear box. The brake is actuated by an actuating ring serving also for disengaging the clutch. The actuating ring is connected to a diaphragm spring of the clutch release bearing and an axially extending sleeve. If the clutch linings are worn, the clutch engagement position of the diaphragm spring and the actuating ring is shifted in axial direction. In view of compensating for this axial shift, the sleeve is composed of two sleeve members, one of them being connected to the diaphragm spring and the other of them being connected to the actuating ring through the clutch release bearing and both of them being interconnected by thread means. In case the frictional linings of the clutch are worn to a predetermined degree, the two sleeve members defining the sleeve are threaded with respect to each other, so that the axial position of the actuating ring under clutch engagement conditions is restored, whereby the brake action becomes independent of the wear conditions of the clutch.
