The invention relates to an electric steering gear and a vehicle. The electric steering gear comprises a shell, an input shaft, a steering assembly, a sector shaft and a power assisting assembly, the input shaft penetrates through the shell and can rotate relative to the shell, the steering assembly comprises a steering screw connected with the input shaft and a steering nut arranged on the steering screw in a sleeving mode, and the steering nut can move in the axial direction of the steering screw when the steering screw rotates; the gear sector shaft is in transmission connection with the steering nut, the power assisting assembly comprises a power assisting screw and a motor, the power assisting screw is arranged at the end, away from the steering screw, of the steering nut in a penetrating mode, and the output end of the motor penetrates through the shell and is in transmission connection with the power assisting screw to drive the power assisting screw to rotate so as to drive the steering nut to move in the axial direction of the steering screw. According to the electric steering gear, torque output by the motor is used for driving the power assisting screw to rotate and driving the steering nut to move, power assisting is achieved, worm and gear transmission is not needed, the transmission efficiency is improved, and the electric steering gear can output larger torque.
本申请涉及一种电动转向器及车辆。电动转向器包括壳体、输入轴、转向组件、齿扇轴和助力组件，输入轴穿设于壳体并能够相对壳体转动，转向组件包括与输入轴连接的转向螺杆以及套设于转向螺杆上的转向螺母，转向螺母能够在转向螺杆转动时沿转向螺杆的轴向移动，齿扇轴与转向螺母传动连接，助力组件包括助力螺杆和电机，助力螺杆穿设于转向螺母远离转向螺杆的一端，电机的输出端穿过壳体并与助力螺杆传动连接，以驱动助力螺杆转动从而带动转向螺母沿转向螺杆的轴向移动。上述电动转向器，利用电机输出的扭矩驱动助力螺杆转动，带动转向螺母移动，实现助力，由于无需采用蜗轮蜗杆传动，提高了传动效率，使电动转向器能够输出更大的扭矩。
