Description

Technical Field

[0001] This application relates to the field of air suspensions, and more particularly, to an air suspension system for a vehicle. Background Art

[0002] An automotive suspension system is a general term for all force-transmitting connecting devices between the vehicle frame and the axle or wheels. Its function is to transmit the forces and torques acting between the wheels and the vehicle frame, buffer the impact force transmitted from the uneven road surface to the vehicle frame or body, and attenuate the resulting vibrations to ensure smooth driving of the vehicle. Compared with traditional suspensions, due to the relatively complex structure of air-adjustable suspensions, the probability and frequency of their failures are also higher than those of coil spring suspension systems.

[0003] Currently, in an air suspension system, control is achieved by pushing the airbag to inflate and deflate. The airbag is usually installed at a corresponding position by bolts. For the disassembly, replacement, repair, and maintenance of the airbag in the later stage, the installation of multiple bolts greatly reduces the disassembly and assembly efficiency, affecting the maintenance of the entire system.

[0032] Please refer to Figure 1 , 2 , 3, 4, and 5. The shock absorption component 200 includes an extension arm 210, an airbag body 220, a connecting plate 240, and a clamping member 260. The extension arm 210 is disposed at one end of the guiding arm 120. A T-shaped block 222 is provided at the top of the airbag body 220. An arc-shaped clamping hole 241 is formed in the connecting plate 240. The connecting plate 240 is installed on one side of the vehicle frame 110. The T-shaped block 222 is inserted and clamped in the arc-shaped clamping hole 241. The clamping member 260 is disposed on one side of the extension arm 210 and is clamped to the bottom of the airbag body 220. A shock absorber 270 is rotatably provided at the end of the extension arm 210.

[0033] Among them, an opening is formed at one end of the arc-shaped clamping hole 241, and the top dimension of the T-shaped block 222 is the same as that of the opening. By forming the opening, it is used for the T-shaped block 222 to pass through the opening.

[0034] In this embodiment, the clamping member 260 includes a housing 261, a clamping rod 262, a moving plate 263, and a spring 264. The housing 261 is fixedly connected to the bottom of the extension arm 210. One end of the clamping rod 262 is slidably disposed in the housing 261.

By providing the housing 261, the clamping rod 262, the moving plate 263, and the spring 264, using the elastic action of the spring 264, without other external forces, the spring 264 pushes the moving plate 263 and the clamping rod 262, so that the clamping rod 262 keeps clamping the T-shaped block 222.

[0035] In a specific implementation, an operation block 2631 is formed by extending the moving plate 263. The operation block 2631 slidably penetrates through the housing 261. By providing the operation block 2631, it is convenient to manually move the operation block 2631 during disassembly to operate and move the moving plate 263 to compress the spring 264.

[0036] In a specific embodiment, an insertion block 221 is provided at the bottom of the airbag body 220. A through hole 2211 is formed in the insertion block 221.

[0037] The working principle of the air suspension system of this vehicle: During use, when it is necessary to disassemble, maintain or repair and replace the airbag body 220, move the operation block 2631 to operate the moving plate 263 to squeeze the spring 264. The moving plate 263 drives the clamping rod 262 out of the through hole 2211. Rotate the airbag body 220 to drive the T-shaped block 222 to rotate. Rotate the T-shaped block 222 to the opening, squeeze the bottom of the airbag body 220 to move the insertion block 221 out of the extension arm 210, and then the airbag body 220 can be taken out. During installation, squeeze the airbag body 220, align the T-shaped block 222 with the opening, align the insertion block 221 with the hole on the extension arm 210, release the airbag body 220 and rotate it in the reverse direction, rotate the T-shaped block 222 into the arc-shaped clamping hole 241 to be clamped, and the insertion block 221 passes through the extension arm 210. Similarly, move the operation block 2631 to operate the moving plate 263 to squeeze the spring 264. When the insertion block 221 passes through the extension arm 210 and then release the operation block 2631, by the elastic action of the spring 264, without other external forces, the spring 264 pushes the moving plate 263 and the clamping rod 262, so that the clamping rod 262 keeps clamping the T-shaped block 222, thereby realizing the convenient disassembly and assembly of the airbag body 220, avoiding the installation method of multiple bolts, and improving the efficiency of disassembly, repair and maintenance.
