Description

Technical Field

[0001] The utility model belongs to the technical field of air suspensions, and in particular relates to a single-side reverse-mounted air suspension device. Background Art

[0002] Air suspension is a type of automobile suspension, which consists of an air compressor, a control unit, an accumulator, a body sensor, 3 body and 4 air spring extension acceleration sensors and acceleration sensors. The air suspension includes air springs, shock absorbers, guide mechanisms and body height control systems. Bag-type air springs are usually used. The air suspension has the function of adjustable hardness and softness. Its working principle is to collect signals through sensors and transmit the signals to the control unit. The control unit then sends adjustment instructions based on the signals to adjust the hardness of the air springs and at the same time regulate the shock absorber damping to achieve the ideal elastic state.
