Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In figure: 1. check valve; 2. vacuum switch; 3. master cylinder; 4. vacuum booster; 5. regenerative braking induction apparatus; 6. electric vacuum pump; 7. vacuum accumulator device; 8. left front braking; 9. brake pedal; 10. right front braking; 11. it is automatically controlled; 12. left back braking; 13. brake behind the right side; 14. movable motor.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to restriction of the present utility model:
Electrically propelled traction vehicle vacuum servo and vicarious regeneration double brake system, including electric vacuum pump 6, regenerative braking induction apparatus 5, brake pedal 9, it is characterized in that: on front side of described electric vacuum pump 6 upper end, be provided with check valve 1, vacuum accumulator device 7 it is provided with on rear side of electric vacuum pump 6, vacuum accumulator device 7 is provided with vacuum switch 2, vacuum booster 4 it is provided with on the right side of vacuum accumulator device 7, upper surface, vacuum booster 4 front end is provided with master cylinder 3, vacuum booster 4 rear end is connected to brake pedal 9, regenerative braking induction apparatus 5 it is connected on the right side of brake pedal 9, it is arranged below turning to assembly on rear side of brake pedal 9, two ends, assembly left and right are turned to brake 10 before being connected to left front braking 8 and the right side, assembly rear is turned to be arranged with movable motor 14 in parallel, described movable motor about 14 two ends brake 13 after being connected to left back braking 12 and the right side, and movable motor 14 right-hand member front is connected to automatically controlled 11.
When being embodied as: 1) switch on power, vacuum switch 2 closes, electric vacuum pump 6 works after about 20s by check valve 1 to vacuum accumulator device 7 and vacuum booster 4 evacuation, when the vacuum pressure in vacuum accumulator 7 reaches-80KPa, vacuum switch 2 disconnects, electric vacuum pump 6 quits work, check valve 1 ensure that the vacuum of vacuum accumulator device 7 and vacuum booster 4 does not leak simultaneously, adds the security performance of product.
2) when brake pedal 9, vacuum booster 4 promotes master cylinder 3 to export brake fluid and brakes 13 to left front braking 8, right front braking 10, left back braking 12, the right side, realize brake operating of the present utility model, the vacuum pressure of vacuum accumulator device 7 and vacuum booster 4 declines to some extent in the process, when vacuum pressure drops to-55KPa, vacuum switch 2 again closes and electric vacuum pump 6 is worked, it is ensured that the vacuum pressure of vacuum accumulator device 7 and vacuum booster 4; While brake pedal 9, regenerative braking induction apparatus 5 detects the stroke of brake pedal 9 and carrys out braking rear-wheel by automatically controlled 11 generation regenerative braking signals control movable motors 14, the size of regenerative braking force is controlled by regenerative braking induction apparatus 5, the more big then regenerative braking force of braking distance is more big, during regenerative braking, movable motor 14 is by automatically controlled to battery charging, the more big then charging current of regenerative braking force is more big, has reclaimed the energy to greatest extent.
3) driving process does not accelerate, not braking time, vehicle is in freewheeling condition, and when not stepping on brake pedal, electric vacuum pump 6 and regeneration brake system all do not work, and have saved the energy.
