Whole brakes is in braking procedure, and electromagnetic valve break-make frequently will not produce bigger vibration and noise.
When brake system of car needs supercharging, electronic control unit 107 receives instruction, controls motor 106 and transports
Dynamic, provide power for whole electromechanical brake booster system, control motor 106 and impart power to snail by shaft coupling 108
Bar 103, worm screw 103 concomitant rotation, due to the big retarding ratio characteristic of worm gear 104 and worm screw 103, will control what motor 106 exported
Power carries out slowing down and increasing moment of torsion, so on the one hand can provide sufficiently large power-assisted, on the other hand ensure that control motor
The movement velocity that the speed of 106 drive brake pedal 101 motions and driver apply adapts, it is ensured that the pedal sense of driver
Feel.Rotating of worm gear 104 drives brake pedal 101 to rotate, in this role, it is achieved that piston push rod around the core wheel of worm gear 104
The axial linear movement of 105, promotes master cylinder piston 109 to move in master cylinder housing 111, and this part is applied to master cylinder piston 109
On power, be electromechanical brake booster system produce power-assisted.In braking procedure, driver can be at brake pedal 101
The pedal force that a part of muscular strength of upper applying, this muscular strength i.e. driver provide, say, that driver acts on brake pedal
Upper power is pedal force.Power-assisted is coupled on brake pedal 101 with the muscular strength of driver, jointly makees by piston push rod 105
Being used on master cylinder piston 109, the mobile meeting of master cylinder piston 109 causes supercharging or the minimizing of master cylinder hydraulic pressure.When release brake pedal
When 101, brake pedal 101 is promoted and returns to original state by back-moving spring 112.
The electromechanical brake booster system that the present invention provides can be under realizing Brake energy recovery operating mode, it is ensured that driver
Pedal sense constant, when automobile need slow down time, first brake energy recovering system works, utilize electromotor carry out slow down system
Move rather than pass through hydraulic braking.Now, constant in order to reach the driver pedal sense when Brake energy recovery, driver steps on
During lower brake pedal, the electronic control unit of braking booster system changes electromagnetic valve state in brake circuit, makes brake fluid move
Accumulator to hydraulic control unit, master cylinder hydraulic pressure declines, if master cylinder hydraulic pressure is less than pedal force, it is necessary to electromechanical is braked
Booster system provides anti-power-assisted, to ensure that pedal force is constant, namely controls the defeated of motor by electronic control unit
Enter voltage, by the rigid connection structure of worm gear Yu brake pedal, it is achieved required anti-assist function.Due to road surface operating mode not
With, the maximum deceleration that brake energy recovering system can be provided by also is different, the electronics of electromechanical brake booster system
Control unit through processing, can obtain the maximum deceleration that brake energy recovering system is real-time according to the road surface signal of Real-time Collection
Degree, to control the time of hydraulic brake circuit intervention car braking, the brake force provided when brake energy recovering system meets not
During car deceleration demand, electronic control unit changes the state of corresponding hydraulic valve in brake circuit, and brake fluid enters automobile
Wheel cylinder, provides corresponding brake force for vehicle.Therefore, the electromechanical brake booster system that the present invention relates to may be implemented in difference
Under the operating mode of road surface, during Brake energy recovery effect, co-ordination between electromotor and brake fluid system, driver pedal sense is protected
Hold constant.
