Vehicle brake system of the present utility model also includes the main brake dress for providing the first brake disc 1 brake force
Put, to the braking completely for realizing vehicle.As shown in figure 17, main breaking zone device is with brake fluid system of the prior art substantially
Identical, the main breaking zone device mainly includes operating mechanism, the caliper 7 of master cylinder 23 and the 3rd being sequentially connected, master cylinder
23 and the 3rd caliper 7 by oil pipe connect, the structure of the caliper 7 of master cylinder 23 and the 3rd is such as those skilled in the art institute
As known, will not be described here, the 3rd caliper 7 and the first brake disc 1 are engaged composition caliper disc of the prior art
Brake, the effect of master cylinder 23 is that the mechanical energy being input into from operating mechanism is converted into into hydraulic energy, enters the 3rd caliper 7
Row corresponding actions.
As shown in figure 17, operating mechanism includes the brake pedal 22 being rotatably arranged on vehicle frame, is arranged at braking and steps on
Partial gear 25 on plate 22 and the tooth bar 24 for engaging with partial gear 25 and being connected with the push rod of master cylinder 23, tooth bar
24 to be movably arranged on vehicle frame, push rod as master cylinder 23 power input part, partial gear 25 and braking
The synchronous rotary of pedal 22, partial gear 25 is used to drive tooth bar 24 to move along a straight line, and then can pass through tooth bar 24 by machinery
Master cylinder 23 can be transferred to.Partial gear 25 constitutes incomplete gear mechanism, the gear teeth of partial gear 25 with tooth bar 24
Whole pitch-line it is not covered with, used as driving gear, tooth bar 24 is the normal tooth bar for being disposed with continuous tooth to partial gear 25.No
Have uniform gear teeth on gear 25 completely has region of gear teeth and does not arrange one of the gear teeth without region of gear teeth, when have region of gear teeth and
When tooth bar 24 is engaged, partial gear 25 can drive tooth bar 24 to move when rotating, and now master cylinder 23 and the 3rd is braked
Pincers 7 can be braked work；When without region of gear teeth and tooth bar 24 just pair, partial gear 25 can not drive tooth bar 24 when rotating
Move, now the caliper 7 of master cylinder 23 and the 3rd can be braked work.Brake pedal 22 is in initial position
When, on partial gear 25 without region of gear teeth just to tooth bar 24, when braking, brake pedal 22 and partial gear 25 first revolve
Turn certain angle, during rotating to an angle, tooth bar 24 is remained stationary as, namely the caliper 7 of master cylinder 23 and the 3rd
Do not immediately begin to be braked work, until the region of gear teeth that has on partial gear 25 is engaged with tooth bar 24.
