The invention relates to the technical field of vehicles, and provides an electric pump, an active hydraulic suspension and an automobile. The electric pump comprises two electric pump sets, each electric pump set comprises a motor with a motor shaft and a pump connected to the motor shaft, the pumps are arranged at the ends, in the axial direction of the motor shafts, of the motors, and the ends, away from the corresponding pumps, of the two electric pump sets are connected; the electric pump further comprises a driving module and a control module, the driving module is arranged on the peripheral side of the motor in the radial direction of the motor shaft, the driving module is provided with a power circuit and a driving circuit which are electrically connected, and the driving circuit is electrically connected with the motor; the control module is arranged at the ends, away from the pump, of the motors in the axial direction of the motor shaft and located between the two motors, and the control module is provided with a main control circuit electrically connected to the drive circuit. According to the electric pump, the occupied axial space is reduced, high-voltage electronic elements and low-voltage electronic elements are separated in space, and signal interference is reduced.
本申请涉及车辆技术领域,提供了一种电动泵、主动液压悬架及汽车。该电动泵包括两组电动泵组,每组电动泵组均包括具有电机轴的电机和连接于电机轴的泵,泵设于电机沿电机轴轴向的一端,两组电动泵组于背离各自泵的一端连接;电动泵还包括驱动模组和控制模组,驱动模组沿电机轴径向设于电机的外周侧,驱动模组设有电源电路和驱动电路,两者电性连接,且驱动电路与电机电性连接;控制模组沿电机轴轴向设于电机背离泵的端部,并位于两个电机之间,控制模组设有电性连接于驱动电路的主控电路。本申请提供的电动泵缩减了轴向空间占用,且促使高低压电子元件在空间上分隔开,降低信号干扰。
