The invention discloses a bidirectional pressure buildup automobile redundant brake unit which comprises a three-outlet liquid storage tank, the three-outlet liquid storage tank is provided with a double-cavity serial connection type pedal main cylinder, and a pedal displacement sensor is arranged on a power connection portion of the double-cavity serial connection type pedal main cylinder. A brake pedal is arranged at the connecting end of a power connecting part on the double-cavity series connection type pedal main cylinder, a wheel cylinder is arranged on the lower portion of the double-cavity series connection type pedal main cylinder, and a double-winding hollow shaft motor servo voltage buildup unit is arranged at an outlet in the left side of the three-outlet liquid storage tank. The double-winding hollow shaft motor servo voltage buildup unit comprises a double-winding hollow shaft motor assembly and a motor main cylinder piston. Compatibility of an X-type brake loop and an H-type brake loop of an automobile can be achieved, the high-level automatic driving requirement can be met without damage through the additionally-adopted structure, a brake unit without an actual brake pedal can be formed only by removing a mechanical main cylinder loop, brake redundancy can still be kept, and the point cannot be achieved in the prior art.
本发明公开了一种双向建压的汽车冗余制动单元,包括三出口储液罐,所述三出口储液罐设置有双腔串联式踏板主缸,所述双腔串联式踏板主缸上动力连接部设置有踏板位移传感器,所述双腔串联式踏板主缸上动力连接部的连接端设置有制动踏板,所述双腔串联式踏板主缸下部设置有轮缸,所述三出口储液罐的左侧出口设置有双绕组空心轴电机伺服建压单元,所述双绕组空心轴电机伺服建压单元包括双绕组空心轴电机总成、电机主缸活塞。本发明能够实现汽车X型制动回路和H型制动回路的兼容,另采用的构型可无损兼容高级别自动驾驶需求,仅需要去掉机械主缸回路即可构成无实际制动踏板的制动单元,并且仍能保持制动冗余,该点在现有技术中无法做到。
