H-shaped arm for pneumatic suspension

Abstract

The invention relates to an H-shaped arm for a pneumatic suspension. The H-shaped arm comprises an H-shaped arm main body, mounting holes are formed in four end corners of the H-shaped arm main body correspondingly, and meanwhile, mounting seats corresponding to the four end corners of the H-shaped arm main body are arranged at the upper end of an axle and the side end of a cross beam correspondingly. The H-shaped arm main body is integrally manufactured and formed by two cross arms and a longitudinal arm, and the joints of the two cross arms and the longitudinal arm are connected with each other through an arc-shaped transition, wherein the two mounting holes in the H-shaped arm main body connected with the axle are parallel to each other or form a certain angle. The H-shaped arm for thepneumatic suspension has the advantages that by improving a traditional V-shaped pushing seat connected to the upper end of an axle and utilizing the design of the H-shaped arm, one connecting point at the upper end of the axle is changed into two connecting points, and the two connecting points are designed to be parallelly connected with the H-shaped arm, thus the stability of connection of theaxle is ensured, accordingly a series of parts such as a transverse stabilizing rod and a vertical connecting rod can be eliminated, and the H-shaped arm is convenient to mount.

Description

technical field [0001] The invention relates to an automobile air suspension, in particular to an H-shaped arm for the air suspension. Background technique [0002] The air suspension is mainly used for various load vehicles, and its working principle is to deliver compressed air to the air chamber of the air spring to change the elastic height of the vehicle when it is under pressure. There are height sensors near the front and rear wheels. According to the output signal of the height sensor, the microcomputer judges the change of the height of the vehicle body, and then controls the compressor and the exhaust valve to make the air spring compress or extend, thereby increasing the height of the vehicle body. constant effect. The specific work of the constant height of the vehicle body is: the height sensor is installed on the frame and connected to the bridge through the swing rod. When the height of the vehicle body and the bridge changes, an induced current is generated ...

AI Technical Summary

Problems solved by technology

In the above structure, there are many parts required for its installation, and it is necessary to install a lateral stabilizer bar and a vertical connecting rod on the outer end of the support arm to ensure the stability of the axle and the vehicle body. There are many parts required, and the installation is inconvenient , and when installing the stabilizer bar, it is necessary to open an arc-shaped groove at the lower end of the support arm, which is not convenient for processing
