What is the working principle of a car steering system?
1 Answers
The main working principle of a car steering system is to transmit signals from the steering wheel. Here are the detailed insights: 1. When the car is turning, the torque (steering) sensor 'feels' the torque of the steering wheel and the intended direction of rotation. These signals are sent to the electronic control unit via a data bus. The electronic control unit then issues action commands to the motor controller based on the transmitted torque, intended direction, and other data signals. The motor then outputs the corresponding amount of rotational torque as needed, thereby generating power steering. 2. For mechanical hydraulic systems, regular checks should ensure that the power steering fluid in the reservoir is not lacking, and avoid holding the steering wheel at full lock for too long. Pay attention to whether the steering feels heavy or if there is any noise. If such symptoms occur, be sure to check issues like the V-belt of the oil pump and internal pressure. 3. For electro-hydraulic systems, also regularly monitor the level of power steering fluid. When the warning light comes on, be sure to conduct an inspection. 4. For electric power steering systems, if there are issues with heavy steering or difficulty in turning, always use instruments to measure and diagnose the problem.
