The chassis consists of a drive train, a driving system, a steering system and a brake system.
1. Transmission system introduction
It is mainly composed of a clutch, a transmission, a universal joint, a transmission shaft and a transaxle.
Clutch: Its function is to smoothly or temporarily separate the power of the engine from the transmission, so that the driver can perform operations such as starting, stopping, shifting, and the like of the vehicle.
Transmission: It consists of a transmission case, a transmission cover, a first shaft, a second shaft, an intermediate shaft, a reverse shaft, a gear, a bearing, an operating mechanism, etc., and is used for automobile shifting and variable output torque.
2. Driving system introduction
It consists of a frame, axle, suspension and wheels. The basic function is to support the quality of the whole car and to ensure the car's driving.
Leaf springs and shock absorbers: The role of leaf springs is to maintain a flexible connection between the frame and the body and the wheels or axles. The function of the shock absorber is to moderate the vibration when the car is subjected to shock. The shock absorber is used in parallel with the leaf spring.
3. Introduction to steering system
It consists of steering wheel, steering gear, steering knuckle, steering knuckle arm, tie rod and straight rod. The function is steering.
Front wheel positioning: In order to keep the car running in a stable straight line, the steering is light, and the wear of the tire and the steering mechanism during driving is reduced. The installation between the front wheel, the steering kingpin and the front axle has a certain relative position. It is called "front wheel positioning". It includes the kingpin backwards, the production and sales inward, and the front wheel toe. The toe value is the difference between the front edge distances of the two front wheels and the rear edge distance.
4. Brake system introduction
The braking performance of a motor vehicle is the performance of the vehicle forcibly stopping in the shortest time.
The role of the hand brake: the hand brake is a device that prevents the car from slipping when parked, and in special cases, with the foot brake.
Hydraulic brake structure: The hydraulic brake device consists of a brake pedal, a master cylinder, a sub-pump, a drum (wheel) brake and a fuel pipe.
Air brake device: It consists of brake pedal, air compressor, air pressure gauge, brake valve, brake air chamber, drum (wheel) brake and air pipe.
