The invention relates to the technical field of electronic boosters, in particular to a double-piston electronic booster which comprises an electronic booster main cylinder, a main piston, an auxiliary piston and an electronic booster push rod. One end of the electronic booster push rod penetrates through the middle of the main piston and is fixedly connected with the auxiliary piston, the other end of the electronic booster push rod is hinged to the brake pedal, the diameter of the auxiliary piston is smaller than that of the main piston, a displacement sensor is installed in the electronic booster main cylinder, and the output end of the displacement sensor is connected with the input end of the electronic booster control unit. And the control end of the electronic booster control unit is connected with the driving mechanism. The device provided by the invention is simple in structure and reliable in assistance, can provide safe backup for the electronic booster, and can still realize safe and reliable deceleration and braking of the vehicle under the condition that the control unit of the electronic booster fails.

    本发明涉及电子助力器技术领域,尤其涉及一种双活塞电子助力器,其包括电子助力器主缸、主活塞、辅助活塞及电子助力器推杆,主活塞位于电子助力器主缸内并由驱动机构驱动往复运动,电子助力器推杆一端穿过主活塞中部且与辅助活塞固接,电子助力器推杆另一端与刹车踏板铰接,辅助活塞直径小于主活塞直径,电子助力器主缸内安装有位移传感器,位移传感器输出端与电子助力器控制单元输入端连接,电子助力器控制单元控制端与驱动机构连接。本发明提供的装置结构简单,助力可靠,能够为电子助力器提供安全备份,在电子助力器控制单元失效的情况下仍然能够实现车辆安全可靠减速制动。
