[0002] Special and heavy-duty off-road vehicles have large loads and complex road conditions. Conventional air suspensions can only meet load-bearing capacities below 13 tons and cannot meet the overweight load-bearing requirements of heavy vehicles. Conventional air suspensions are prone to overloading, deformation, dislocation and other faults, affecting the safe driving of the vehicle. Utility Model Content

[0003] This application aims to solve the problems of conventional air suspension, such as overloading, deformation, and misalignment, and adopts the following technical solutions:

[0004] An air suspension comprising:

[0005] The axle and the frame are symmetrically mounted with two air suspension structures, the air suspension comprising a front bracket, a guide leaf spring, a shock absorber, an upper bracket, a lower bracket, and a bracket;

[0006] Among them, the front bracket is connected to the frame, and the upper bracket is installed on the frame; one end of the guide leaf spring is connected to the front bracket and the other end is connected to the axle through the lower bracket and the lower bracket; there are two shock absorbers, one end of the two shock absorbers is connected to the front bracket, and the other end is connected to the lower bracket, and forms a certain inclined angle with the horizontal plane; the airbag is installed between the upper bracket and the lower bracket.

[0007] Furthermore, the air suspension further comprises a thrust rod, one end of which is connected to a lower bracket in the air suspension structure, and the other end of which is connected to the vehicle frame.

[0008] The present application also provides a vehicle comprising the air suspension as described above.

[0009] Beneficial effects of this application:

[0010] 1. In this application, the airbag is arranged on the axle, which can effectively improve the load capacity of the air suspension and avoid overloading.

[0011] 2. In this application, the shock absorber is in an inclined state and can effectively withstand the vertical and horizontal vibrations of the frame, while the airbag can withstand the vertical vibrations of the frame, effectively preventing the airbag from being deformed or dislocated due to lateral forces.

[0015] To make the above features and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0016] In the description of this application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0017] Reference Figure 1 and 2 , the present application provides an air suspension, comprising:

[0018] Axle 10 and frame 9, two air suspension structures are symmetrically mounted on the frame 9, the air suspension includes a front bracket 6, a guide leaf spring 4, a shock absorber 1, an upper bracket 3, a lower bracket 5, and a bracket;

[0019] Among them, the front bracket 6 is connected to the frame 9, and the upper bracket 3 is installed on the frame 9; one end of the guide leaf spring 4 is connected to the front bracket 6 and the other end is connected to the axle 10 through the lower bracket 5 and the bracket; there are two shock absorbers 1, one end of the two shock absorbers 1 is connected to the front bracket 6, and the other end is connected to the lower bracket 5, and forms a certain inclined angle with the horizontal plane; the airbag 2 is installed between the upper bracket 3 and the lower bracket 5.

[0020] Specifically, the upper end of the front bracket 6 is fixedly mounted on the lower surface of the vehicle frame 9, and the upper bracket 3 is also fixedly mounted on the lower surface of the vehicle frame 9. One end of the guide leaf spring 4 is rotatably mounted on the lower end of the front bracket 6, and the other end is provided with a lower bracket 5 on the upper part and a lower bracket 7 on the lower part; the lower bracket 7 is used to support the axle 10, and the lower bracket 7 is connected to the lower bracket 5 by bolts, thereby connecting the lower bracket 5, the guide leaf spring 4, the axle 10 and the lower bracket 7 into one body. The airbag 2 is installed between the upper bracket 3 and the lower bracket 5 to withstand vertical vibration. Each air suspension structure includes two shock absorbers 1, and each two shock absorbers 1 are symmetrically arranged and form a certain tilt angle with the horizontal plane. The angle can be 25°-50° to withstand horizontal and vertical vibrations and avoid affecting the airbag 2, causing deformation or dislocation of the airbag 2.

[0021] Reference Figure 2 The air suspension further includes a thrust rod 8, one end of which is connected to a lower bracket 7 in the air suspension structure, and the other end is connected to the vehicle frame 9. By connecting the vehicle frame 9 and one of the lower brackets 7, the thrust rod 8 can also effectively prevent the airbag 2 from being deformed or misaligned when the vehicle turns.
