It is the development trend of automobile especially new-energy automobile, actively brake is to manipulate intelligentized important component, and traditional
The master cylinder that vacuum booster drives, due to its reasons in structure, it is impossible to compatibility/realization active brake function, can not realize
The regulation of pedal sense.The utility model by increasing hydraulic cavities, the 3rd piston, both can as the reinforcing terminal of brake pedal,
Realize that power-assisted acts on, can also directly control supercharging accumulator to establish hydraulic pressure in hydraulic cavities by vehicle control syetem, and lead to
Crossing the 3rd piston promotes push rod to drive each wheel brake operation, realizes and actively brakes.In addition, can be very square by supercharging accumulator
Just the hydraulic pressure size of hydraulic cavities is adjusted, to match the different dynamics of different motorists and firmly be accustomed to, so as to vary with each individual ground
Realize the regulation of pedal sense.
Preferably, the 3rd piston is slidably connected on the port of cylinder body one end, push rod is plugged on the 3rd piston.3rd
Piston is the afterbody of the transmission mechanism on used in new energy vehicles master cylinder, is the output end of master cylinder, promotes wheel system
The push rod of dynamic device work is plugged on the 3rd piston, and attachment structure is easy and effective, existing certain adaptive adjustment capability, have because
Have from response agency without departing from connection.
Preferably, end where the push rod of cylinder body is installed with shield, push rod is slided to wear and is connected on shield.Shield is lived the 3rd
The slide contact part port of plug and cylinder body, and the connecting portion of push rod and the 3rd piston are all shielded in closing space, are formed
Protection, prevent debris enters from causing jam.
Preferably, push rod free end is provided with dismountable push rod cup.Push rod cup is direct drive of wheel braking on push rod
The position of device work, it is easy to wear, set dismountable push rod cup to be changed after being easy to abrasion, so as to be more readily maintained.
Preferably, being threadedly coupled a dynamics adjusting nut on push rod, dynamics adjusting nut offsets with push rod end surface.It is logical
The threaded engagement position of dynamics adjusting nut and push rod is overregulated, can adjust the cooperation depth of push rod cup and push rod, changes push rod
The extension elongation of head, and then realize the adjustment of operating force.
The beneficial effects of the utility model are：
Realize and actively brake, improve automobile operation intelligent level.The utility model is by setting up hydraulic cavities, the 3rd work
It plug, supercharging accumulator, can directly control supercharging accumulator to establish hydraulic pressure in hydraulic cavities, realize and actively brake, improve automobile
Manipulate intelligent level.
