Brief description of the composition of air suspension: In the history of the development of transportation, the comfort of vehicles has always been a problem that many people are committed to solving. However, with the emergence of air suspension, the problem of comfort has also been improved. The air suspension system consists of pneumatic ball valve, shock absorber, air supply unit guide mechanism and body height control system. Now let's get familiar with the functions of various parts of the air suspension.
1. The pneumatic ball valve can be divided into three types according to the structure type: capsule type, membrane type and composite type. The bladder type pneumatic ball valve, which is composed of pneumatic ball valve with cord and tightly sealed closed air, has single section and multi section types. The more the number of sections, the better the elasticity, but the poor tightness;
2. Shock absorber is mainly used to attenuate body vibration;
3. The guide mechanism is composed of longitudinal thrust rod and transverse thrust rod, which is used to transmit the longitudinal force, lateral force and torque generated during driving and braking between the vehicle body and the axle. The pneumatic ball valve can only bear the vertical load.
4. The air supply unit contains air compressor, single valve, air circuit, air tank, solenoid valve, etc. It is mainly used to generate, store and control compressed air.
5. The body height control system is divided into mechanical control system and electronic control system. The height control sensors are installed near the front, rear, left and right suspensions. Its function is to check, check and measure the height of the car body, convert it into an electronic signal, and input it into the control device ECU. The perfect connection between the current passing control and the air suspension system through the sub technology makes the performance of the air suspension system perfectly displayed.
