Abstract

A combined type air suspension system without a thrust bar comprises a vehicle frame, a vehicle axle, a guide arm and a vehicle frame transverse beam. One end of the guide arm is connected with the vehicle frame through a guide arm support, and the other end of the guide arm is connected with an air spring through an air spring transverse beam. The end of the vehicle frame transverse beam is connected with the guide arm support through the vehicle frame. The guide arm is located below the vehicle axle. An upper cover plate and a lower cover plate are arranged on the upper side and the lower side of the vehicle axle. A U-shaped bolt strides over the upper cover plate, the lower cover plate and the guide arm in sequence and then is connected with a U-shaped bolt base plate. The lower cover plate is connected with a shock absorber, two lug plates are symmetrically arranged on the two side faces of the lower cover plate, and adjusting bolts are arranged on the lug plates and abut against the guide arm. A large gasket is arranged on the portion, connected with the guide arm support, of the guide arm. By the adoption of the design, the vehicle frame crack risk and the cost are reduced, the trafficability is improved, the steering performance is guaranteed, the tire abrasion is reduced, and the abrasion of the guide arm support can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobile air suspension, in particular to a composite air suspension system that does not match a thrust rod, and is mainly suitable for reducing the risk and cost of vehicle frame cracking and improving vehicle trafficability. Background technique [0002] Compared with the leaf spring suspension, the air suspension can effectively improve the ride comfort of the vehicle, making the ride safer and more comfortable; when the load changes, it can automatically adjust to maintain the body height; the vehicle equipped with the air suspension has small vibration and can reduce the impact on The damage of electrical, instrumentation and other accessories of the body and chassis reduces the maintenance cost of the vehicle; reduces the impact on the road, protects the road surface, and reduces the maintenance cost of the highway, so it is more and more widely used in automobiles. [0003] Chinese patent, the a...
