Description

TECHNICAL FIELD

[0001] The utility model relates to a dismounting tool technical field, concretely is a kind of automobile shock absorber dismounting tool. BACKGROUND

[0002] The term automobile shock absorber is a general term in the automotive chassis industry. The automobile shock absorber is actually a vibration damper. In the suspension system, the elastic element vibrates due to impact. To improve the ride comfort of the vehicle, a shock absorber is installed in parallel with the elastic element in the suspension system to attenuate vibration. The shock absorber used in the vehicle suspension system is usually a hydraulic shock absorber. The working principle of the shock absorber is that when the frame (or vehicle body) and axle move relative to each other due to vibration, the piston in the shock absorber moves up and down, and the oil in the shock absorber chamber repeatedly flows from one chamber to another through different pores. The shock absorber and the elastic element bear the tasks of shock absorption and vibration reduction. If the damping force is too large, the suspension elasticity will be damaged, and even the shock absorber connecting parts will be damaged. Therefore, a shock absorber dismounting tool is needed to dismount and replace the damaged shock absorber.

[0003] The existing shock absorber is mostly manually dismounted by repair workers using their tools. However, there are some problems during dismounting. First, if the connection between the shock absorber and the connecting part is too tight, the repair worker will have difficulty manually unscrewing the screw, which is time-consuming and labor-intensive, and may not guarantee that the tightly installed screw can be removed. Second, the spring limiting part at the upper end of the damaged shock absorber also needs to be manually unscrewed. The difficulty of manually unscrewing the screw increases when the connection is too tight. In addition, the pushing force generated by the spring when removing the spring limiting part also needs to be limited by using another tool, otherwise the spring will burst out and cause injury to the personnel. Therefore, a shock absorber dismounting tool is needed to solve the above problems. SUMMARY
