When piston 121 is moved along first direction simultaneously compression elastic piece 14, after the completion of brake or when vehicle driving, stop to movable chamber
Continue to be discharged into hydraulic oil, while 14 elastic rebound of elastic component, provide one and hydraulic-driven opposite effect power to piston piece 12,
So that piston piece 12 moves in a second direction, piston piece 12 drives brake component 15 far from brake disc 31, to realize brake component 15
It is separated completely with brake disc 31, for the brake 10 of the more existing single-acting hydraulic control of this programme, passes through elastic component 14 and liquid
Pressure driving is so that piston piece 12 can be with bidirectional-movement, and in realization vehicle travel process, brake component 15 is kept completely separate with brake disc 31,
The temperature for reducing brake 10 avoids sealing element 17 from damaging phenomena such as causing permeability, reduces the wear intensity of brake component 15, extends system
The service life of dynamic device 10 improves the reliability and safety that brake 10 is braked.
