Electric power steering system, as an important part of modern automotive technology, aims to improve the convenience and safety of driving. The system mainly consists of the following key components:

1. Steering control mechanism: It is the starting point of the steering system and is responsible for receiving the driver's steering instructions. Steering controls typically include a steering wheel, steering shaft, and steering column, which work together to ensure that the driver's steering intent is transmitted accurately and quickly to the steering gear.

2. Steering gear: Steering gear is the core component of the steering system, responsible for converting the torque and movement from the steering control mechanism into appropriate steering action. In electric power steering systems, the steering gear is usually equipped with motors and sensors to provide the required power and adjust in real time according to factors such as speed and steering Angle.

3. Steering transmission mechanism: The steering transmission mechanism is responsible for transmitting the output of the steering device to the wheel, so that the wheel can turn according to the driver's intention. It usually includes steering tie rods, steering knuckle arms and other components, which need to withstand various forces and moments generated during steering.
