An electric power steering system consists of a torque sensor, vehicle speed sensor, electronic control unit (ECU), electric motor, and electromagnetic clutch, among other components. It utilizes the power generated by the electric motor to assist the driver in steering. Below is a classification of power steering systems: 1. Mechanical Hydraulic Power Steering System. A mechanical hydraulic power steering system typically comprises components such as a hydraulic pump, oil pipes, pressure and flow control valve body, V-belt, and oil reservoir. 2. Electro-Hydraulic Power Steering System. Its main components include an oil reservoir, power steering control unit, electric pump, steering gear, and power steering sensor. Here, the power steering control unit and the electric pump are integrated into a single structure. 3. Electric Power Steering System. This system uses the power generated by an electric motor to assist the driver in steering.
