Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a vehicle axle air suspension securing device. Background Technology
[0002] In the modern automotive industry, traditional metal springs, due to their physical limitations, struggle to simultaneously meet the dual demands of comfort and handling. Air suspension systems, through the combination of high-pressure air springs and electronic control units, achieve dynamic adjustment of vehicle height and suspension stiffness. This variable characteristic makes them widely used in luxury sedans, SUVs, and new energy vehicles, becoming a key technological solution for balancing the demands of complex road conditions with ride comfort.
[0003] Existing air suspension systems use fasteners such as bolts or clips to fix their upper and lower ends to ring-shaped seats on the vehicle's frame and axle, respectively. This ring-shaped seat design provides a certain degree of support and stability, ensuring that the suspension system can effectively withstand and buffer various impacts and vibrations from the road surface during vehicle operation, thereby improving the vehicle's ride comfort and safety.
[0004] However, existing air suspension systems generally use bolts as the main fixing method. This traditional fixing method has relatively weak fixing ability and is difficult to provide sufficient stability and reliability. During maintenance, the installation and disassembly process becomes quite cumbersome and difficult due to the characteristics of bolt fixing. Moreover, when the air pump inflates the air spring, the intake pipe may fall off due to excessive air pressure. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a vehicle axle air suspension fixing device, which aims to improve the problem that the traditional air suspension fixing method has relatively weak fixing ability, is difficult to provide sufficient stability and reliability, and is difficult to install and disassemble during maintenance.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an air suspension fixing device for vehicle axles, including a support arm, with connecting blocks provided on both sides of one end of the support arm, and an installation component provided on the outer wall of the connecting block, wherein the connecting block is rotatably connected to an air suspension through the installation component, and the connecting component is provided on the outer wall of the air suspension;
[0007] The mounting assembly includes a housing, the outer wall of which is fixedly connected to one side of the outer wall of the connecting block, a limit block fixedly connected to the outer wall of the housing, a spring provided at one end of the outer wall of the housing, an unlocking block fixedly connected to one end of the spring, and the other end of the spring fixedly connected to one end of the outer wall of the housing. A fixed ball is provided inside the housing, a steel ball is slidably connected to the inner wall of the housing, and a first bolt is fixedly connected to the outer wall of the steel ball.
[0008] Furthermore, the connecting assembly includes an air inlet, which is disposed on the outer wall of the air suspension. A clamp is provided on the outer wall of the air inlet. A second bolt is rotatably connected to one side of the outer wall of the clamp, and a hinge is fixedly connected to the other side of the outer wall of the clamp. A nut is rotatably connected to one end of the second bolt. A sealing ring is attached to one side of the outer wall of the air inlet, and an air intake pipe is attached to the outer wall of the sealing ring.
[0009] Furthermore, the inner wall of the unlocking block is slidably connected to the outer wall of the outer casing.
[0010] Furthermore, the first bolt is rotatably connected inside the connecting block.
[0011] Furthermore, one end of the air suspension is rotatably connected to the outer wall of the first bolt.
[0012] Furthermore, the outer wall of the sealing ring is attached to the inner wall of the clamp piece.
[0013] Furthermore, the outer wall of the intake pipe is attached to the inner wall of the clamp plate.
[0014] Furthermore, one side of the inner wall of the nut is attached to one side of the outer wall of the clamp plate.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, when the air suspension is installed, the lower end of the air suspension is placed in the corresponding installation position on the support arm, and then the first bolt is inserted into the reserved hole on the connecting block.
