Example Embodiment

[0020] Examples:

[0021] Such as Figure 1-2 As shown, the embodiment of the present invention provides a variable-diameter hydraulic buffer structure automobile shock absorber assembly, including a body 1, a working cylinder 2 is arranged inside the body 1, a guide 4, and a working cylinder 2 are arranged at the end of the working cylinder 2 The end close to the guide 4 is reduced in diameter. The working cylinder 2 is provided with a piston rod 3 inside. The free end of the piston rod 3 penetrates the guide 4 and extends to the outside of the body 1. The diameter-reducing area of ​​the port is set as a buffer zone 5. The outer surface of the piston rod 3 is provided with an inner limit 6, and the outer surface of the inner limit 6 is fixedly installed with a buffer 7, and the working cylinder 2 is retracted close to one end of the guide 4 Diameter reduction treatment, and an inner limit 6 is welded on the piston rod 3. A buffer 7 is added to the inner limit 6, when the shock ...

Abstract

The invention provides a diameter change type hydraulic buffer structure automobile shock absorber assembly, and relates to the technical field of automobile parts. The diameter change type hydraulicbuffer structure automobile shock absorber assembly comprises a body. A work cylinder is arranged in the body. A guide device is arranged on the end portion of the work cylinder. Necking diameter change processing is conducted on the end, close to the guide device, of the work cylinder. A piston rod is arranged in the work cylinder. The free end of the piston rod penetrates through the guide device and extends to the outer portion of the body. The portion, located on the area subjected to necking diameter change, in the work cylinder is arranged into a buffer zone. An inner limiting part is arranged on the outer surface of the piston rod. A buffer is fixedly installed on the outer surface of the inner limiting part. By conducting necking diameter change processing on the work cylinder, thedamping of the buffer zone can be larger than two or more times of the normal shock absorber recovery damping force, the buffering power value is increased in a doubled manner according to the reciprocation speed, and a strong buffering effect is achieved.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile shock absorber assembly with variable diameter hydraulic buffer structure. Background technique [0002] In order to quickly attenuate the vibration of the frame and the body and improve the ride comfort and comfort of the car, the suspension system of the car is generally equipped with a shock absorber. The shock absorber is a vulnerable part during the use of the car. The performance of the shock absorber will directly affect the driving stability of the car and the life of other parts. Therefore, the shock absorber should always be in good working condition. [0003] During the use of conventional automobile shock absorbers, if the car is driving in bad road conditions such as bumps and potholes, the vibration of the shock absorber is relatively large compared to that of the flat road surface, and it is easy to stretch the shock absorber to the stretchin...
