Title:
WET DISC BRAKE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/145028
Kind Code:
A3
Abstract:
This wet disc brake system comprises a set of discs (1) rigidly connected respectively to a rotary member (8) and to an element (7) fixed relative to the chassis of the vehicle on which said system is mounted, said discs being subjected to the action of a piston (2), capable of exerting pressure on the discs in the direction of the rotary member, said piston (2) itself being permanently subjected to the action of a system of springs (3) bearing against an element (5) fixed relative to the chassis of the vehicle, and of which the action is neutralised by a hydraulic fluid received for this purpose in a relief chamber (6) of the piston (2), delimited between the element (7) that is fixed relative to the chassis and a shoulder provided inside said piston, said chamber being supplied by a source of hydraulic pressure. This system further comprises a second piston (4), mounted in opposition to the piston (2), and receiving the end of the system of springs (3) opposite that which bears against the piston (2), said second piston (4) being likely to move in translation along the same translation axis as the piston (2) and towards the latter under the action of a hydraulic fluid generated by said source of hydraulic pressure or by a second source of hydraulic pressure.
