Description

Technical Field

[0001] This utility model relates to the field of shock absorbers, and more particularly to a motorcycle shock absorber with low vibration amplitude. Background Technology

[0002] Shock absorbers are used to suppress the oscillations caused by the rebound of springs after absorbing shocks, as well as impacts from the road surface. They are widely used in vehicles to accelerate the attenuation of chassis and body vibrations, thereby improving ride comfort. When driving over uneven roads, although the shock-absorbing springs can filter road vibrations, the springs themselves still have reciprocating motion; the shock absorber is used to suppress this spring bounce. If the shock absorber is too soft, the vehicle body will bounce up and down; if the shock absorber is too stiff, it will create too much resistance, hindering the normal operation of the springs. In the process of modifying the suspension system, stiff shock absorbers must be matched with stiff springs, and the stiffness of the springs is closely related to the vehicle's weight. Therefore, heavier vehicles generally use stiffer shock absorbers, which are connected to the crankshaft.

[0003] In existing shock absorbers, the preload of some shock absorber springs is fixed during use, which makes it impossible for users to adjust the preload according to different scenarios, thus affecting user experience. Therefore, we propose a motorcycle shock absorber with low vibration amplitude to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a motorcycle shock absorber with low vibration amplitude to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] In this utility model, a low-vibration-amplitude motorcycle shock absorber is installed in a suitable position on the vehicle. The user can then turn the lever to extend the small spring. Next, the user turns the handwheel, which causes the shaft to rotate. The shaft then drives the worm to rotate. Since the worm meshes with the worm wheel, the worm wheel drives the screw to rotate, causing block number three to begin horizontal movement. Furthermore, when block number three moves;

[0013] In this utility model, a low-vibration-amplitude motorcycle shock absorber is described. Both the first and second connecting rods begin to move. Then, the first plate begins to slide inside the outer shell. As the first plate continues to move vertically, the connecting cylinder can be compressed or extended. At this time, the user can adjust the tension of the shock-absorbing spring, which allows the user to use it for different needs. The user can easily fix the device to the vehicle using the first block and the threaded block. Furthermore, the shock-absorbing spring is a high-strength spring, which facilitates vehicle shock absorption, allowing the vehicle to vibrate at a low frequency.

[0014] This utility model has a reasonable structural design. Through the cooperation between the first connecting rod, the second connecting rod, the first block, and the second block, the user can adjust the tension of the shock-absorbing spring, thereby adjusting the tension of the device. This allows the user to adjust the appropriate preload according to their needs in different scenarios. Attached Figure Description
