1. Leaf spring: It not only plays the role of shock absorption and guidance, but also is the most widely used elastic element in automobile suspension.
2. Spiral spring: it does not need lubrication, is not afraid of dirt, has small mass, occupies small longitudinal space but can only bear vertical load, and cannot play the role of friction and vibration reduction, and is widely used in independent suspension.
3. Torsion bar spring: ensure the elastic connection between the wheel and the frame.
4. Gas spring: Its spring function is realized by the compressibility of gas.
5. Lateral stabilizer bar: improve ride comfort.
auto mechanics
1. Engine: 2 mechanisms and 5 series engines: crank-connecting rod mechanism; Valve mechanism; Fuel supply system; Cooling system; Lubrication system; Ignition system; Start the system.
2. Chassis: The function of the chassis is to support and install the automobile engine, its parts and assemblies, to form the overall shape of the automobile, and to accept the power of the engine to make the automobile move and ensure normal running.
3. Car body: The car body is installed on the frame of the chassis for drivers and passengers to ride or load goods. The body of a car or bus is generally an integral structure, and the body of a truck is generally composed of a cab and a cargo box.
4. Electrical equipment: Electrical equipment consists of power supply and electrical equipment. The power supply includes storage battery and generator; Electrical equipment includes the starting system of engine, the ignition system of gasoline engine and other electrical equipment.
