The invention discloses a multi-drive vacuum pump brake auxiliary system of a pure electric vehicle. The multi-drive vacuum pump brake auxiliary system of the pure electric vehicle comprises a brake pedal, the brake pedal is connected with a vacuum booster, the vacuum booster is connected with a vacuum tank, the vacuum tank is connected with a vacuum pump, the vacuum pump comprises a shell, the lower portion of the shell is in pivot joint with a first crankshaft, and a first connecting rod is arranged in the middle of the first crankshaft; and a first connecting rod driving piston exhausts air in vacuum tank, one end of the first crankshaft is connected with a first driving shaft through a first electromagnetic clutch, the first driving shaft is connected with a driving axle half shaft and used for driving the first crankshaft to rotate, the other end of the first crankshaft is connected with a second driving shaft through a second electromagnetic clutch, and the second driving shaft is connected with a vehicle body and is used for driving the first crankshaft to rotate. The problem that an electric vacuum pump adopted in the prior art consumes too much electric quantity of a vehicle-mounted battery so that the load of the vehicle-mounted battery is increased is solved.

    本发明公开了一种纯电动汽车的多驱动真空泵制动辅助系统。该纯电动汽车的多驱动真空泵制动辅助系统包括制动踏板,制动踏板连接有真空助力器,真空助力器连接有真空罐,真空罐连接有真空泵,真空泵包括壳体,壳体的下部枢接有第一曲轴,第一曲轴的中部设置有第一连杆,第一连杆驱动活塞对真空罐进行抽气,第一曲轴的一端通过第一电磁离合器连接有第一驱动轴,第一驱动轴与驱动桥半轴连接,用于驱动第一曲轴转动,第一曲轴的另一端通过第二电磁离合器连接有第二驱动轴,第二驱动轴与车身连接,用于驱动第一曲轴转动。本发明解决了现有技术采用的电动真空泵会过多消耗车载电池的电量,从而增加车载电池负载的问题。
