Novel air suspension guide arm and automobile comprising same

Abstract

The invention relates to a novel air suspension guide arm and an automobile comprising the same. The invention discloses the novel air suspension guide arm, and the novel air suspension guide arm comprises a control arm, wherein the control arm comprises an upper side plate, a lower side plate, a vertical plate and a torsion sleeve, and is characterized in that the torsion sleeve is connected withone or any of the upper side plate, the vertical plate or the lower side plate, the vertical plate is positioned between the upper side plate and the lower side plate, and one end, far away from thetorsion sleeve, of the control arm is connected with a first axle fixing plate. The beneficial effects are as follows: the air suspension guide arm consists of the upper side plate, the lower side plate and the vertical plate, and the air suspension guide arm has simple structure, safety and reliability and reasonable structure. Compared with the control arm of the existing metal plate structure,the novel air suspension guide arm is more stable, higher in strength and better in safety. The lower side plate is of a structure which gradually narrows and then widens from one end of the torsion sleeve, and can bear larger force and is more durable.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a novel air suspension guide arm and an automobile containing the guide arm, which are applied in an automobile air suspension system. Background technique [0002] In order to improve vehicle ride comfort, reduce fuel consumption and reduce tire wear, many truck OEMs have adopted liftable air suspensions. Air suspension refers to a connecting device between the body, frame and wheels. 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 height of the vehicle body; the vehicle equipped with the air suspension has small vibration, which can reduce the impact on the electrical, instrumentation and vehicle body. And the damage of other accessories of the chassis, reduce the maintenance cost of the vehicle; reduce the impact on the road, protect the road sur...

AI Technical Summary

Problems solved by technology

In the existing technical scheme, the guide arm is located under the axle, and the U-bolt is connected to the axle, so the lateral displacement of the whole vehicle is relatively large when turning, and the guide arm bears a large lateral force, and it is not stable enough. The cover is prone to early wear, and it will produce abnormal noise when turning

The guide arm cantilever is long, and the design structure is unreasonable. In order to ensure sufficient strength, the design is large in size and heavy in weight.
