Embodiment
Please refer to oil pressure braking handle group is shown shown in Fig. 1 to Fig. 3, in figure, it includes leader's 1, one base of seat
2nd, a brake lever 3, a piston 4, stress deformation and two hollow gasbags 5 and a spring 6 that voluntarily recover, wherein：The handle base
1 have be coaxially disposed a runner 12 to connect brake callipers along its axially arranged main oil groove 11, and with the main oil groove 11
7, the handle base 1 be additionally provided with second mate's oil groove 13 and with the main spaced-apart relation of oil groove 11, and the main oil groove 11 respectively with this two
Secondary oil groove 13 is connected；The base 2 is together articulated in the handle base 1 with brake lever 3, and the base 2 is connected with the piston 4, and
The piston 4 along the main oil groove 11 towards the runner 12 close to away from direction displacement；And two hollow gasbag 5 be connected to respectively this two
Secondary oil groove 13；The two ends of the spring 6 are butted between the main oil groove 11 and piston 4 respectively.
It should be noted that the utility model embodiment is so that main oil groove 11 is filled with fluid with secondary oil groove 13 as an example, and say
Bright its brake of bicycle oil pressure brake system.
Kenel is used on the utility model as shown in Figures 3 to 8.Press brake lever 3 and interlock piston 4, fluid is by the master
Oil groove 11 pushes to clamp 7 through piston 4 so that pushing and pressing lining 71 clamps down on the both sides of disc 73, while being become with the oil liquid pressure of clamp 7
Suction produced by changing draws the fluid of the secondary oil groove 13 and forces the volume expanding distortion of two hollow gasbag 5 by the road.
Brake lever 3 is discharged, is resetted through the elastic restoring force pushing and pressing piston 4 of spring 6, i.e. piston 4 is towards the opposite direction of runner 12
Displacement, piston 4 is moved to script position, and this process piston 4 produces suction in the main oil groove 11 and draws part oil in clamp 7
Liquid, more has part fluid to flow to the secondary oil groove 13.
And in brake process is repeated for a long time, the existing considerable degree of abrasion of lining 71 in clamp 7 cause clamp
Piston 72 in 7 needs more fluid that it could be maintained to promote lining 71 to the frictional position of disc 73, and the secondary oil groove of this case
