The steering device is the device that controls the direction of the car. It must meet the following requirements:

1, work safety and reliability: the steering system directly affects the safety of the car, so all parts are required to have enough stiffness, strength and wear resistance, connecting parts must be firm and reliable, with the car driving speed, the reliability of the work put forward higher requirements.

2, the control of light and flexible: when the car driving on the narrow and small curved road to turn, the steering system must ensure flexible, smooth, accurate rotation of the front wheel. When the car runs straight, the steering wheel should be stable, without jitter and shimmy phenomenon.

3, appropriate steering force: if there are no other obstacles, the steering force is larger when the car stops, and decreases with the increase of the speed of the car. Therefore, in order to drive easily and get good feedback from the road, the handling should be lighter at low speeds and heavier at high speeds.

4, smooth rotary performance: when the car turns, the force acting on the steering wheel should be appropriate, flexible and smooth steering, with automatic positive effect.

5. The impact from the road is small: the steering device must not occur because the road surface is not smooth and make the steering disc out of control and cause inversion, and the impact force should be small.
