Advantages of air suspension
(1) Unique design guarantees superior performance
The drive shaft air suspension only uses a unique high strength stiffness design. The problem of vibration and fracture of metal ball valve is eliminated without using leaf spring and U-bolt. This rigid guide arm, together with other parts of the air suspension, provides the best performance combination: comfortable ride, easy installation and less maintenance. The air suspension is designed according to the unique parallelogram design principle. Its torque rod is always parallel to the connecting line of the guide arm, which minimizes the change of the pinion angle (P), thus reducing the wear of the spline and universal joint, reducing the swing of the transmission shaft, and making the vehicle drive smoothly and quietly. In addition, the suspension system can maintain load balance when the vehicle accelerates and brakes.
(2) Axle installation features
The rigid guide arm of the pneumatic butterfly valve is connected to the frame support with a bushing. When accelerating and braking, the axle is allowed to have controlled movement to reduce the stress of the axle housing and prevent damage. This is an important consideration for high torque/low speed generator vehicles. When braking, the axle moves slightly forward and downward to keep the tire close to the ground and shorten the braking distance. Increased tire and brake pad life.
(3) System simplicity
The greater the up and down motion of the axle, the better the ride comfort, and the greater the ability of the suspension system to absorb road vibration. The maximum travel of air suspension exceeds that of any other type of suspension. Because the unique design makes the travel of the axle in the vertical direction larger, the pneumatic butterfly valve can absorb greater vibration load before the axle reaches its travel limit. The vertical travel of other air suspensions is short and often reaches its travel limit, resulting in hard impact. （
4) No large impact load
The axle of any suspension system may move to its upper limit travel when the air suspension cushion makes a sharp turn and passes the pit in the loading and unloading area. The air suspension has a cushion to withstand the impact load in this case. Another function of the buffer is that in case of damage, the buffer pad can act as a suspension so that the vehicle can continue to drive at a lower speed.
