The invention provides a double-source electric power steering pump and a new energy vehicle. The double-source electric power-assisted steering pump comprises a double-acting steering oil pump (1) and a power-assisted steering motor (2), the power-assisted steering motor (2) is used for providing steering power for the double-acting steering oil pump (1), the power-assisted steering motor (2) is connected with a high-pressure controller and a low-pressure controller (3), the high-pressure controller controls a high-pressure power source to supply power to the power-assisted steering motor (2), and the low-voltage controller (3) controls the low-voltage power supply to supply power to the power-assisted steering motor (2) after the high-voltage battery fails. According to the double-source electric power-assisted steering pump, the problem that a single-source power-assisted steering pump cannot continuously provide assisted power after high-voltage power failure can be solved.

    本申请提供一种双源电动助力转向泵和新能源汽车。该双源电动助力转向泵包括双作用转向油泵(1)和助力转向电机(2),助力转向电机(2)用于为双作用转向油泵(1)提供转向动力,助力转向电机(2)分别与高压控制器和低压控制器(3)连接,高压控制器控制高压电源对助力转向电机(2)供电,低压控制器(3)在高压电池失效后控制低压电源对助力转向电机(2)供电。根据本申请的双源电动助力转向泵,能够解决单源助力转向泵在高压电断电后无法继续提供助力的问题。
