SELF-ENERGISING SPREADING DISC BRAKE FOR VEHICLES

摘要

The brake application of a spreading disc brake is effected by moving pressure plates in opposite directions into engagement with friction discs. This can be achieved hydraulically by pressurization of a pressure space between an annular cylinder in the plate and an annular piston in the plate and which works in the cylinder. Also this can be achieved mechanically by a brake-applying pull rod which is connected to a cranked lever pivotally connected to the plate and acting on the plate. The lever may act directly on the plate or it may act on the plate through an automatic slack adjuster.
