Problems solved by technology

[0004] The present invention aims at the disadvantages that the existing brake booster requires a hydraulic source or a vacuum source as a power boosting source, resulting in many power boosting system equipment, complex structure, unstable power boosting, and problems such as noise and weight gain. The on-board power supply is used as a booster source, with small size, compact structure, stable boosting effect, and no noise at the same time, light weight brake booster system

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] According to a specific embodiment of the present invention, such as figure 2 and 3 As shown, the brake booster system provided by the present invention includes a pedal push rod 1, a rubber reaction disc 7, a master cylinder push rod 8, a brake pedal 25 and a housing 28, and the brake booster system also includes a motor 12, a worm 13 , Worm wheel 14, nut 15, spring 16, piston 17, return springs 18 and 19, retaining ring 20 and bearings 21 and 22.

[0015] Wherein, the motor 12 is connected with the worm 13 . The worm 13 meshes with a worm wheel 14 . Worm wheel 14 is connected to housing 28 by bearings 21 and 22 and is free to rotate about its axis within the cavity of housing 28 . And the worm wheel 14 is connected with the nut 15 by threads, preferably the thread has a self-locking function, so only when the worm wheel 14 rotates...

Abstract

A boosting system for the braking of electric car or the car with mixed power system is composed of the push rod of pedal, reactive rubber disc, the push rod of master cylinder, braking pedal, casing, electric motor, worm-gear set, nut, spring, piston, restoring springs, baffle ring and bearings.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a brake booster system for vehicles. Background technique [0002] In the vehicle, the brake booster system is used to make up for the insufficient pressure of the driver when the brake pedal is stepped on to strengthen the braking effect of the braking system. At present, the brake boosters used in the field of automobile manufacturing include hydraulic servo brake boosters and vacuum brake boosters. Among them, the hydraulic servo brake booster uses a high-pressure hydraulic source or a high-pressure oil source as a boost source, and by changing the brake master cylinder, designing a special hydraulic pipeline, and controlling the boost pressure, brake boost is achieved. The vacuum brake booster uses the pressure difference between the vacuum degree generated by the engine throat or specially equipped vacuum equipment and the atmospheric pressure on the two ends of the ...
