Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a vehicle shock absorber. Background Art

[0002] Automotive shock absorbers, also known as automotive shock absorbers or shock absorbers, are one of the most important components in the automotive chassis system. Their main function is to suppress the shock caused by the rebound of the spring after absorbing the shock and the impact from the road surface, ensuring the smoothness and comfort of the vehicle's driving. However, shock absorbers are vulnerable parts during the use of the car, so it is very important to regularly check and maintain the working condition of shock absorbers to ensure the smoothness of the car's driving and the service life of other parts.

[0003] During the use of existing vehicle shock absorbers, the shock absorbing damping force of the shock absorber is usually set to a fixed value, which makes the vehicle unable to adapt to changes in different road conditions. On bumpy roads, the vehicle body will produce large vibrations, resulting in reduced driving stability and affecting the driving experience. At the same time, the impact force cannot be effectively reduced, causing the suspension system to be under excessive pressure, aggravating the wear of the suspension system and reducing the service life of vehicle components. In addition, since the spring will produce wear and elastic fatigue after long-term use, the spring needs to be replaced regularly. However, the common shock absorber spring is cumbersome to disassemble and needs to be disassembled with the help of different tools. It is difficult to quickly replace the spring, which reduces the maintenance efficiency of the shock absorber. Utility Model Content

The piston rod 171 is provided to facilitate its up and down movement inside the cylinder 1, and absorbs and converts vibration energy through oil damping; a sealing gasket 172 is provided at the bottom of the cylinder 1. The sealing gasket 172 is provided to facilitate improving the sealing of the cylinder 1 and prevent the shock absorbing oil inside the cylinder 1 from leaking out; one end of the piston rod 171 is fixedly connected to a connecting seat 173. The connecting seat 173 is provided to facilitate the connection of the shock absorber with other parts of the car.

[0029] Working principle: When in use, when the damping force of the shock absorber needs to be adjusted, the rotating wheel 52 is manually rotated to drive the bidirectional screw 53 to rotate, so that the sliding shaft 6 threadedly connected to the outer side of the bidirectional screw 53 moves. While the sliding shaft 6 slides inside the sliding groove 9, it drives the first rotating rod 101 to move along. As the first rotating rod 101 and the second rotating rod 103 rotate around the rotating shaft 102 as the center of the circle, the moving plate 2 is driven to move through the change of the rotation angle, thereby completing the adjustment of the stroke length of the shock absorbing spring 4 and adjusting the damping force. When the shock absorbing spring 4 needs to be removed, the push button 122 is pushed to make the sliding rod 14 slide down to the arc along the highest point on the surface of the limit block 13, and the sliding rod 14 loses its limit. Then, it is reset by the rebound force generated by the second spring 15, and the limit on the block 161 is disengaged. Then, the block 161 can be removed from the slot 163, so that the shock absorbing spring 4 is released from the fixed state.
