Problems solved by technology

[0004] The air suspension in the prior art has the following problems: the guide spring 03 has the functions of bearing and guiding. Although the structure is simple, it requires high strength and performance of the guide spring 03, and the suspension device is relatively heavy, which is not conducive to the stability of the vehicle. Weight reduction; In addition, the rigidity of the guide spring 03 is relatively large, which is not conducive to the improvement of the ride comfort of the vehicle; during the movement, most parts such as the axle and air spring are located above the guide spring 03, and the guide spring 03 has Larger motion interference, and makes the space occupied; the guide spring 03 has to bear vertical load, lateral load and torsional load, the reliability is low; the shock absorber 09 is located between the axle 013 and the air spring 07. The heat generated during the process will cause thermal damage to the air spring 07

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...

Abstract

The invention provides an air suspension, comprising: a vehicle frame, a front-end bracket, a rear-end bracket, a bearing spring, an air spring, a shock absorber, a vehicle axle, a beam, a guiding thrust rod and a lateral thrust rod; the bearing spring is Z-shaped, the front end of the bearing spring is connected to the front-end bracket, and the rear end is connected to the rear-end bracket; the front-end bracket is installed on the vehicle frame, and the upper end of the shock absorber is hinged to the vehicle frame, The lower end is hinged with the rear end bracket, so that the bearing spring has a first part close to the vehicle frame and a second part away from the vehicle frame; the axle is suspended below the first part, and the crossbeam is installed Above the second part, the air spring is installed between the vehicle frame and the beam; one end of the guide thrust rod is connected to the front end bracket, and the other end is connected to the axle; the lateral thrust rod One end is connected to the vehicle axle, and the other end is connected to the vehicle frame. The invention has compact structure and good smoothness.

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...
