Mounting method for air spring vehicle chasis and its supporting rod

Abstract

The present invention is the process of installing vehicle chassis with air suspension and the support bar therefor. The installing process includes the first installing support bar between the vehicle frame and the axle or between the upper damper bracket and the lower damper bracket to make the vehicle frame in normal running height, the subsequent inflating the air bag, and final removing the support bar. The support bar has simple structure, easy use and high universality. The process of installing vehicle chassis with air suspension is simple, reasonable, high in efficiency, high in installation quality and low in cost, and may be applied widely.

Description

Technical field [0001] The utility model relates to an installation method of a vehicle suspension device. A support member is also involved. Specifically, it is an installation method of an air suspension vehicle chassis and its support rods. Background technique [0002] The existing vehicle air suspension is generally mainly composed of stabilizer bars, stabilizer bar brackets, shock absorbers, shock absorber upper and lower brackets (including brackets with mounting holes and brackets with pins), thrust rods, thrust rod brackets, airbag bases, Airbag bracket, height control sensor and other components. In this type of air suspension solution, the thrust rod bears longitudinal and lateral forces, and the air suspension airbag is arranged between the frame and the axle, mainly bearing and transmitting the load in the direction of gravity. This structure has the following problems in the assembly process: first, the vehicle frame must be raised with a stand, and then com...

AI Technical Summary

Problems solved by technology

This structure has the following problems in the assembly process: first, the frame must be raised with a stand, and then the axle and air suspension airbags and other components must be installed below, and the airbags have not been inflated or underinflated after they are installed

The bench takes up a lot of space and is inconvenient for installation and construction. If the airbag is inflated at the assembly site, the chassis frame can be raised to replace the bench

However, since the components and pipelines on the chassis have not been assembled, it is inconvenient to inflate the airbag during the chassis assembly stage.

At this time, if the platform is removed, the frame will sink greatly, and the chassis frame will not be able to be assembled because the height from the ground is too small.

In particular, this structure still has the following problems in the transfer process after the chassis is assembled: First, the load in the vertical direction of the chassis is mainly carried and transmitted by the buffer block inside the airbag. During the transfer or transportation of the vehicle chassis, when the chassis is lifted , the lifting point is usually on the frame, when the frame rises, it will pull up the axle through the airbag and shock absorber

If there are no protective measures during lifting, the airbag cover may be separated from the airbag body, that is, the airbag may be pulled off.

At this time, the airbag must be reinstalled. Compared with the separate assembly state, it is much more troublesome to reinstall the airbag separately between the assembled frame and the axle, which wastes manpower and material resources, and may also cause the airbag rubber to crack, making the airbag scrapped

Second, during the storage of the chassis, because there is no platform support, the airbag is not inflated or the inflation is insufficient, the frame is pressed against the axle, and the height of the chassis frame from the ground is far lower than the design value, which often crushes other parts on the chassis. Components such as drive shaft joints, etc.
