What Components Make Up Electric Power Steering in Cars?
1 Answers
Electric power steering in cars is composed of components such as a torque sensor, vehicle speed sensor, electronic control unit (ECU), electric motor, and electromagnetic clutch. It utilizes the power generated by the electric motor to assist the driver with steering. Working principle: The torque sensor is connected to the steering shaft. When the steering shaft rotates, the torque sensor activates, converting the relative angular displacement between the input and output shafts caused by the torsion bar into electrical signals, which are then transmitted to the ECU. Electric power steering systems have evolved from traditional mechanical steering systems, using the power generated by an electric motor to aid the driver in steering operations. The electric power steering system primarily consists of three major components: signal sensing devices, steering assistance mechanisms, and electronic control devices.
