Working principle of the present invention is as follows:
(1) when vehicle is manned mode, as shown in Figure 2:
When vehicle is set as manned mode, or under unmanned mode, driver forces to step on pedal to enter and has
When people's driving mode: controller 7 controls so that first switch valve 4 open in usual is in the open state, at normally closed type second switch valve 5
In closed state.
(1) when braking: when driver's brake pedal 3, brake pedal 3 chooses to install around hinge joint pushes brake pedal to push away
Bar 26 is moved to the left, and brake pedal force is transmitted to power assisting device 21 by brake pedal push rod 26, and power assisting device 21 generates power-assisted
It acting on and brake force is passed into second piston bar 22, first switch valve 4 open in usual is opened, and normally closed type second switch valve 5 is closed,
Second piston bar 22 moves to left the hydraulic raising so that second chamber 12, and brake fluid (is switched at this time by first switch valve 4 open in usual
Valve is open state) enter first chamber 11, the hydraulic of first chamber 11 also increases.When continuation brake pedal 3
When, second chamber 12 and the hydraulic of first chamber 11 continue to increase, and it is raised it is hydraulic pass through brake monitor 14 and braking
Pipeline 2 conducts, and finally makes hydraulic in left front brake 15, right front brake 16, right rear brake 17 and right front brake 18
It increases, finally generates brake force.
(2) when releasing braking: driver loosen the brake 3 when, first switch valve 4 open in usual is opened, normally closed type second
The wheelcylinder piston of the closing of switch valve 5, brake pedal 3 and second piston bar 22 and each brake is acted in respective return spring
Lower return, the brake fluid in brake piping 2 push the oil return valve on master cylinder 1 open and flow back to master cylinder 1, and brake fluid finally leads to
It crosses first switch valve 4 open in usual and flows into second chamber 12, realize braking system pressure release, brake force releases.
(2) when vehicle is unmanned mode, as shown in Figure 3:
When vehicle is set as unmanned mode: (1) brake pedal 3 is not generated without active force, power assisting device 21 at this time
Power-assisted effect, second piston bar 22 do not move；(2) controller 7 control so that first switch valve 4 open in usual be in close state,
Normally closed type second switch valve 5 is in the open state.
(1) when braking: after controller 7 issues braking instruction, electric machine controller 24 receives the brake signal of controller 7
When, motor 23 starts, while electromagnetic clutch 25 combines, and the rotary motion of motor 23 is converted to directly by worm gear 10 and worm screw 9
Line movement, worm screw 9 push First piston bar toward moving to left, and master cylinder second piston bar 22 moves to left so that third chamber 13
Hydraulic raising, brake fluid enter first chamber 11 by normally closed type second switch valve 5 (at this time switch valve be open state), and first
The hydraulic of chamber 11 also increases.When motor 23 continues to rotate, third chamber 13 and first chamber 11 it is hydraulic after of continuing rising
Height, and it is raised hydraulic by brake monitor 14 and the conduction of brake piping 2, finally make left front brake 15, right preceding braking
Hydraulic raising in device 16, right rear brake 17 and right front brake 18, finally generates brake force.
(2) when releasing braking: after controller 7 issues releasing braking instruction, motor 23 is inverted, the rotary motion of motor 23
Linear motion is converted to by worm gear 10 and worm screw 9, worm screw 9 drives First piston bar 8 toward moving to right, and the wheel cylinder of each brake is living
The return under the effect of respective return spring is filled in, the brake fluid in brake piping 2 pushes the oil return valve on master cylinder 1 open and flows back to system
Dynamic master cylinder 1, brake fluid flow into third chamber 13 eventually by normally closed type second switch valve 5, realize braking system pressure release, brake force
It releases.Last motor 23 stops operating, while electromagnetic clutch 25 separates.
The present invention also provides a kind of vehicle, including Vehicular brake device, the Vehicular brake device is the various embodiments described above
The Vehicular brake device.
Finally it is noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations.This
The those of ordinary skill in field is it is understood that be possible to modify the technical solutions described in the foregoing embodiments or right
Part of technical characteristic is equivalently replaced；These are modified or replaceed, and it does not separate the essence of the corresponding technical solution originally
