What are the components of a power steering system?
2 Answers
There are various types of power steering systems, which can be categorized into pneumatic, hydraulic, and electric types based on the power transmission medium. Below is relevant knowledge about power steering systems: 1. Components of hydraulic steering systems: A hydraulic steering system consists of many parts, such as the steering pump, steering hoses, steering knuckle arm, internal steering control valve, and steering power cylinder. 2. Definition of electric power steering systems: An electric power steering system is a type of steering system that directly relies on an electric motor to provide assistance. This system eliminates the need for complex hydraulic pipelines, fluid reservoirs, and other hydraulic components.
Last week, I just disassembled the steering system in the workshop. The power steering device mainly consists of several core components: the steering wheel is responsible for receiving driver commands, and the steering column transmits these forces downward. The most critical part is the power assist mechanism. Older vehicles use hydraulic systems, requiring a steering oil pump and hydraulic cylinder to work in coordination; newer models have switched to electric power steering, where the motor directly provides auxiliary torque. The control unit monitors in real-time through the steering angle sensor and automatically adjusts the assist level. Don't forget the transmission components like universal joints and tie rods—without them, the steering wheel can't turn the tires. Regularly checking the steering fluid level and for any leaks is crucial, otherwise, high-speed turns can be very dangerous.
