Braking device i.e. drum brake, for motor vehicle, has locking mechanism provided with telescopic spacebar to lock brake segments in locked position independent of control device i.e. hydraulically controlled piston brake cylinder

摘要

The device i.e. drum brake (10), has static units i.e. brake segments (14, 16), controlled by a control device i.e. hydraulically controlled piston brake cylinder (28), between a released position in which the segments are not in contact with a movable unit i.e. cylindrical brake drum (26), and a locked position. The segments are continuously locked against the drum to immobilize a motor vehicle during parking, in the locked position. A locking mechanism has a transversal telescopic spacebar (40) to lock the segments in the locked position independent of the control device. Independent claims are also included for the following: (1) a method for actuating a braking device for activating a braking function (2) a method for releasing a braking device.
