摘　　要：为克服真空助力器总成的助力效果弱,以及现有应用高压空气作为助力源的气压助力器制动时制动踏板随动性和制动感觉差等缺点,文章研发了一种应用于液压制动系统的气压助力器总成。该总成利用高压空气作为助力源,提高液压制动系统制动能力,同时利用橡胶弹簧和活塞的动态平衡来改善制动踏板随动性和制动踏板感觉。To overcome the poor effect of the vacuum booster,and the disadvantages of the brake pedal follower and brake sensation when the pressure booster is used as a power source with high pressure air,air pressure booster applied to the hydraulic brake system is developed in this paper,the assembly uses high pressure air as a power source,improve the braking ability of hydraulic brake system,at the same time,the dynamic balance of the rubber spring and the piston is used to improve the brake pedal follower and brake pedal sensation.
