Description

technical field

[0001] The invention relates to the field of automobile suspension, in particular to an air suspension. Background technique

[0002] With the further implementation of the country's maximum total mass limit standard for heavy-duty trucks, the lightweight and fuel consumption reduction of heavy-duty commercial vehicles has become the main direction of the development of heavy-duty commercial vehicles. The air suspension device has the characteristics of light weight, which can greatly reduce the weight of the whole vehicle. Compared with the traditional air suspension, the composite air suspension device has the characteristics of low cost, simple mechanism and convenient operation.

[0003] Air suspension in the prior art such as figure 1 As shown, it includes: 01, guide spring bracket, 02, guide spring bolt, 03, guide spring assembly, 04, saddle bolt, 05, shock absorber lower bracket, 06, beam, 07, air spring, 08, air Spring bracket, 09, shock absorber a...

Embodiment Construction

[0036] Next, specific embodiments of the present invention will be further described in detail with reference to the accompanying drawings, and in the following description, the up-down direction is defined as the vertical direction, the front-rear direction is defined as the longitudinal direction, and the left-right direction is defined as the horizontal direction.

[0037] combine Figure 2 to Figure 5 , the air suspension in this embodiment includes: vehicle frame 1, front end bracket 2, guide thrust rod 3, bearing spring 4, guide thrust rod support 5, saddle bolt 6, leaf spring cover plate 7, axle 8, crossbeam 9. Rear end bracket 10, air spring 11, shock absorber 13, height valve assembly 15 and lateral thrust rod 16. The vehicle frame 1 has a pair of longitudinal beams extending in the front-rear direction and parallel to each other. from image 3 It can be seen more clearly that the bearing spring 4 is roughly Z-shaped, the front end of the bearing spring 4 is connect...
