[0002] Automobile suspension is the important system of connecting wheel and vehicle body, its function includes transmission force and torque, buffer impact force and reduce vibration. It is composed of elastic element, shock absorber and guiding mechanism etc. parts. Now on market cab suspension generally has rigid, half floating, full floating three modes, wherein rigid connection is just cab and vehicle body hard connection, there is no any shock-absorbing equipment between the two, and comfort is extremely poor, and half floating is that cab front half part is rigidly connected, only in the rear half part is equipped with mechanical spring plus damping cylinder shock-absorbing equipment, and shock-absorbing performance is improved compared with rigid connection but still insufficient, and full floating can absorb the vibration impact of frame to cab as far as possible, thereby reducing the jolt degree of cab.

When sudden road unevenness or jolt is encountered, the suspension system can not be quickly adjusted to provide optimal support and shock-absorbing effect, and the full floating type uses mechanical spring damping cylinder or air bag type spring for shock-absorbing, wherein the air bag type spring often uses a suspension valve for control to adjust the height and balance of the vehicle body for shock-absorbing. The suspension valve currently used generally adopts mechanical or electromagnetic drive, an electromagnet is used for driving at one end, and the other end is reset by mechanical force such as spring, the structure is relatively complex, component failure is easy to occur, cost is increased, and the electromagnet can be affected by external electromagnetic interference, leading to unstable work, thereby affecting work efficiency.
