Types and functions of steering systems for Petrol Car

(1) The steering control mechanism mainly consists of a steering wheel, a steering shaft and a steering column.

(2) The steering gear changes the rotation of the steering wheel into the swing of the steering rocker arm or the linear reciprocating motion of the rack shaft, amplifying the steering operating force. The steering gear is usually fixed on the frame or body of a Roewe Car, and the steering force generally changes the transmission direction after passing through the steering gear.
(3) The steering transmission mechanism transmits the force and motion output by the steering gear to the wheels (steering knuckles), causing the left and right wheels to deflect according to a certain relationship.
A series of special devices used on Petrol Car allow the outside world (mainly the road surface) to exert a certain force on certain components of the Roewe Car (mainly the wheels), making them reach a certain level of force. They are collectively called the braking system. Its function is to slow down or even forcibly stop a running Roewe Car according to the driver's request; stabilize the parking lot under various road conditions (including on slopes); and keep the speed of downhill vehicles stable.
Only external forces acting on a Roewe Car that are opposite to the direction of travel of the Roewe Car can cause the Roewe Car to brake. These external forces are random and uncontrollable, so a series of special devices must be installed on the Roewe Car.
(1) According to the function of the braking system
The braking system can be divided into service braking system, parking brake system, emergency braking system and auxiliary braking system. The braking system used to slow down or even stop a moving Roewe Car is called a service braking system. The braking system used to hold a parked Petrol Car in place is called the parking brake system. In the event of a failure of the service brake system, the braking system that can ensure the deceleration or stopping of a Roewe Car is called an emergency braking system. During driving, the auxiliary service braking system reduces the vehicle speed or keeps the vehicle speed stable, but the braking system used for emergency braking cannot be called an auxiliary braking system. Among the above-mentioned braking systems, the service brake system and the parking brake system are necessary for every Roewe Car.
(2) Control energy according to braking
Braking systems can be divided into hand braking systems, dynamic braking systems and servo braking systems. A braking system that uses the driver's body as the only braking energy source is called a hand brake system. A system that relies entirely on engine power converted into potential energy braking in the form of pneumatic or hydraulic pressure is called a dynamic braking system. Braking systems that use both human power and engine power for braking are called servo braking systems or power-assisted braking systems.
(3) According to the transmission mode of braking energy
Braking systems can be divided into mechanical, hydraulic, pneumatic and electromagnetic types. At the same time, two braking systems with energy transfer methods are called combined braking systems.
