Description

Technical Field

[0001] The utility model relates to the technical field of air suspension, in particular to a sealing cover. Background Art

[0002] A high-quality SUV must have the comfort of a sedan and the passability of an off-road vehicle. The air suspension system is the best choice to achieve this goal. According to different road conditions and the signal of the distance sensor, the on-board computer will determine the change in vehicle height, and then control the air compressor and exhaust valve to automatically compress or extend the spring, thereby lowering or raising the chassis ground clearance to increase high-speed vehicle stability or passability in complex road conditions. The existing air suspension lacks a reinforcement component between the sealing cover and the suspension, which makes the sealing cover easy to fall off, causing the air suspension shock absorber to fail.

[0003] The existing patent (Announcement No.: CN218986273U) proposes an air suspension steering structure, a sealing cover, a vibration isolation block is arranged at the lower end of the sealing cover, a bearing inner ring seat is sleeved on the outer side of the vibration isolation block, a bearing is arranged on the outer side of the bearing inner ring seat, a fixed seat is arranged on the outer side of the bearing, an upper shell is arranged at the lower end of the fixed seat, the outer diameter of the sealing cover matches the inner diameter of the bearing inner ring seat, and the sealing cover is inserted into the inner ring seat of the bearing during the assembly process. The utility model can realize the front wheel steering while the air suspension seals the air by arranging the sealing cover, the vibration isolation block, the bearing, the bearing inner ring seat, the fixed seat and the upper shell, which not only improves the steering sensitivity of the air suspension steering structure, but also avoids damage to the air suspension steering structure during operation, thereby improving the safety of the structure.

[0004] The above-mentioned air suspension steering structure adopts a technical solution to solve the steering sensitivity of the suspension steering structure. The lower end of the sealing cover is provided with a vibration isolation block, the outer side of the vibration isolation block is sleeved with a bearing inner ring seat, the outer side of the bearing inner ring seat is provided with a bearing, and the outer side of the bearing is provided with a fixed seat. Although this solution can solve the problem that the air suspension can seal the air while realizing front wheel steering, since there is no reinforcement structure between the sealing cover and the suspension, the sealing cover is easily separated from the suspension, causing the suspension failure. Therefore, we propose a sealing cover to solve the above problem. Utility Model Content

[0005] The utility model provides a sealing cover, which solves the current technical problem of no reinforcement structure between the sealing cover and the suspension.

[0014] The above technical solution is adopted: the movable clamping block is arranged in the groove and protrudes from the inner ring of the fixed seat. When the movable clamping block protrudes from the inner ring of the fixed seat, when the fixed seat sleeve is arranged on the suspension, the movable clamping block can squeeze the suspension under the reset of the spring elastic force, so that the cover body will not detach from the suspension.

[0015] Preferably, a curved surface is provided on a side of the movable block away from the groove.

[0016] By adopting the above technical solution, a curved surface is provided on the side of the movable clamping block away from the groove, and the curved surface is conducive to the cover body and the fixing seat in the cover body being clamped on the suspension more smoothly.

[0031] Embodiment 2

[0032] like Figure 1-Figure 4As shown, the clamping assembly 2 includes a fixed seat 21, a plurality of grooves 22 are formed on the fixed seat 21, and movable clamps 23 and tension springs 24 are arranged in the grooves 22. A fixed shaft 25 is arranged between the movable clamps 23 and the grooves 22. The movable clamps 23 are movably arranged on the fixed shaft 25, and the fixed shaft 25 is fixed in the groove 22. The spring 24 is arranged between the groove 22 and the movable clamps 23 and away from the side of the fixed shaft 25. One end of the spring 24 is connected to the movable clamps 23, and the end of the spring 24 away from the movable clamps 23 is connected to the inner wall of the groove 22. The movable block 23 is not fitted with the groove 22, and a space is provided between the side of the movable block 23 close to the groove 22 and the groove 22 for providing the movable block 23 with movement. The movable block 23 is arranged in the groove 22 and protrudes from the inner circle of the fixing seat 21. An arc surface 26 is provided on the side of the movable block 23 away from the groove 22. The cover body 1 is an inverted convex structure. A buffer space 3 is provided in the cover body 1 and below the clamping assembly 2.

[0033] The clamping assembly 2 includes a fixing seat 21, and a plurality of grooves 22 are provided on the fixing seat 21. The grooves 22 are provided with movable clamping blocks 23 and tension springs 24. When the cover 1 is set on the suspension, the clamping assembly 2 is clamped on the suspension. The movable clamping blocks 23 in the grooves 22 squeeze the suspension under the return elastic force of the spring 24, so that the cover 1 will not fall off the suspension. A fixed shaft 25 is provided between the movable clamping block 23 and the grooves 22. The movable clamping block 23 is movably provided on the fixed shaft 25. The movable clamping block 23 can be fixed on the fixed shaft 25.
