Technical Field

[0001] The present application relates to the technical field of air suspension assembly, and in particular to a multifunctional auxiliary device for air suspension assembly. Background Art

[0002] A high-quality SUV must have the comfort of a sedan and the passability of an off-road vehicle. The air suspension system is the best choice to achieve this goal. According to different road conditions and the signal from the distance sensor, the on-board computer will determine the change in vehicle height, and then control the air compressor and exhaust valve to automatically compress or extend the spring, thereby lowering or raising the ground clearance of the chassis to increase high-speed vehicle stability or passability in complex road conditions.

[0003] Air suspension generally includes air springs, shock absorbers and guide mechanisms. Air springs generally use bag-type air springs. During the production process, the air springs need to be pressure tested. In the prior art, air suspensions are generally assembled manually and then pressure tested. The existing pressure test is performed after the assembly is completed and then transferred to the next process for testing. The entire transfer process is relatively cumbersome and wastes manpower and material resources, resulting in low production efficiency.

[0004] Therefore, in order to improve production efficiency, our company places assembly and pressure testing in one process. In order to facilitate production for staff, it is urgent to develop a tooling that can assist in assembly and pressure testing. Utility Model Content
