The invention provides a power-assisted steering system and a vehicle. The power-assisted steering system includes: a motor, a first steering pump provided with a rotating shaft, a first oil inlet and a first oil outlet, a connecting piece respectively connected with the motor and the rotating shaft, an oil tank connected with the first oil inlet, and a steering gear connected with the first oil outlet. In the invention, the motor is mechanically connected with the first steering pump, and the motor rotates to drive the first steering pump to work. Due to the fact that the motor has inertia, even if the motor is powered off, the motor can still continue to rotate in a follow-up period of time due to inertia, the rotating shaft is driven to rotate, the first steering pump is driven to work, the situation that the steering pump cannot work due to the fact that the whole vehicle is powered off is avoided, and the safety of the whole vehicle is improved.
本发明提出了一种助力转向系统及车辆。助力转向系统包括:电机;第一转向泵,第一转向泵设有转动轴、第一进油口和第一出油口;连接件,连接件分别与电机和转动轴连接;油罐,油罐与第一进油口连接;转向器,转向器与第一出油口连接。本发明中,电机和第一转向泵之间机械连接,由电机转动带动第一转向泵工作。由于电机具有惯性,因此,即使电机断电,电机仍会因为惯性而可以在后续一段时间内继续转动、带动转动轴转动、带动第一转向泵工作,避免因整车下电而导致转向泵无法工作,提升了整车安全性。
