Description

Shock-absorbing lubricating structure of two-wheeled vehicle standpipe

The invention relates to a lubricating structure of a shock absorber, and more particularly to a two-wheeled vehicle vertical pipe shock-absorbing lubricating structure formed by sleeves of two kinds of materials.

In addition to the basic means of transportation, bicycles have the characteristics of leisure, sports, and environmental protection, which is in line with the modern people's emphasis on leisure life, fitness and environmental protection. Therefore, bicycles are becoming more and more popular in today's society. In order to increase the riding comfort of a bicycle, a shock absorber is usually provided on a riser such as a front fork, a rear frame, or a seat tube, so as to absorb the impact force transmitted from the road surface during riding, thereby mitigating the vibration effect.

The most common structure of the conventional shock absorber is mainly a shaft is inserted through an outer tube. A compressible and elastic damping device is arranged between the inner wall of the outer tube and one end of the shaft. A lubricating bearing is sleeved between the outer periphery of the shaft, and the bearing is a ball bearing or a roller bearing. The bearing can relatively smoothly move up and down between the shaft and the outer tube. However, the bearings used in this type of shock absorber are not only costly and bulky. Too small tolerances will affect the lifting and sliding between the shaft and the outer tube. Therefore, a certain tolerance is required so that the Increased frequency and power, resulting in short service life.

Therefore, some manufacturers use Teflon bushings (self-lubricating bearings) to replace the above bearings, and use the characteristics of Teflon material to achieve the benefits of low cost, small size, and small tolerances. The strength of this kind of Teflon sleeve is too weak, it will easily crack and lose its effect when subjected to a large impact, short service life, and poor practicality. If you want to increase the strength of the Teflon sleeve by thickening it, it will Losing the advantage of small volume causes the volume to be too large, and it is indeed necessary to improve it.

The inventor has the disadvantages of high cost, large volume, short service life and too weak strength in view of the bearings and Teflon bushings used in the conventional bicycle riser shock absorbers. After various discussions and trials of sample tests, and multiple amendments and improvements, the invention was finally introduced.

The invention provides a two-wheeled vehicle vertical pipe shock-absorbing lubricating structure. The lubricating structure is applied to a two-wheeled vehicle vertical pipe shock absorber and is sleeved between an outer tube and a shaft of the two-wheeled vehicle vertical pipe shock absorber. The outer tube is provided with an inner hole of the tube, the shaft is polygonal, and the lubricating structure includes: a self-lubricating layer, made of a compound material, having an inner hole and an outer peripheral surface. The inner hole is polygonal and is used for The shaft rod is arranged to move up and down and slide in an anti-rotation state; and a protective sleeve is made of metal material and has an inner joint hole and an outer joint surface, and the protective sleeve is sleeved outside the self-moisturizing layer The inner sleeve of the protective sleeve is combined with the outer peripheral surface of the self-lubricating layer. The protective sleeve and the self-lubricating layer pass through the outer tube of the two-wheel vehicle standpipe shock absorber. The joint surface outside the pipe is fixedly combined with the outer pipe of the two-wheeled vehicle riser shock absorber; the self-lubricating layer and the shaft are in mating and sliding contact.

The main purpose of the present invention is that it can not only achieve the benefits of low cost, small volume and small tolerance by the self-lubricating layer, but also cover the outer side of the self-lubricating layer with a protective sleeve, so as to prevent the self-lubricating layer from being greatly impacted When cracking loses effect, durability is improved, and service life is extended.
