Two-wheeled vehicle riser suspension lubrication structure

The invention relates to a lubricating structure of a shock absorber, in particular to a two-wheel vehicle riser suspension lubricating structure formed by combining sleeves of two materials.

In addition to being a basic means of transportation, bicycles are more leisure, sporty and environmentally friendly. They are highly valued by modern people for leisure life, fitness and environmental protection. Therefore, bicycles are becoming more and more popular in the society today. In order to increase the comfort of riding a bicycle, a shock absorber is usually arranged in 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 achieving the effect of mitigating vibration.

Conventional shock absorbers, the most common structure is mainly provided by an outer tube through which a shaft is disposed, and a damping device capable of compressing and projecting is disposed between the inner wall of the outer tube and one end of the shaft, and the inner wall of the outer tube is A bearing for lubrication is disposed around the outer circumference of the shaft, and the bearing is a ball bearing or a roller bearing, and the bearing can be relatively smoothly moved 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, but also have too small a tolerance to affect the lifting and slipping between the shaft and the outer tube, so it is necessary to have a certain tolerance so as to collide during the shock. The frequency and strength increase, resulting in a short service life.

Therefore, the manufacturer uses the Teflon casing (self-lubricating bearing) to replace the above bearing, and the Teflon material has the advantages of low cost, small volume and small tolerance; The strength of the Teflon casing is too weak. When it is subjected to a large impact, it is easy to crack and lose its effect. The service life is short and the practicability is not good. If you want to increase the strength of the Teflon casing by thickening, it will Losing the small size has the effect of making the volume too large, and it is necessary to improve it.

The present inventors have the disadvantages of high cost, large volume, short service life, and too weak strength in view of the conventional lubrication bearing and Teflon sleeve used in the bicycle riser shock absorber, which is the idea of design and design. After extensive investigation and trial sample testing, and multiple corrections and improvements, the present invention was finally introduced.

The invention provides a two-wheeled vehicle riser suspension lubricating structure, wherein the lubricating structure is applied to a two-wheeled vehicle riser shock absorber, and is disposed between an outer tube of one of the two-wheeled vehicle riser and a shaft. The outer tube is provided with a tube inner hole, and the shaft is polygonal. The lubricating structure comprises: a self-wetting layer made of a compound material, having an inner hole and an outer peripheral surface, the inner hole being polygonal for providing The shaft rod is disposed in an anti-rotation state, and the movable sleeve is made of a metal material, and has an inner joint hole and an outer joint surface. The protection sleeve is sleeved on the outer side of the self-wetting layer. Covering, the inner connecting hole of the protective sleeve is combined with the outer peripheral surface of the self-wetting layer, and the protective sleeve and the self-wetting layer are disposed in the outer tube of the two-wheeled vehicle riser shock absorber, the protective sleeve The outer joint surface of the tube is combined with the outer tube of the two-wheeled vehicle riser and the outer tube; the self-wetting layer and the shaft are in a sliding contact that can slide up and down.

The main object of the present invention is that it can not only achieve the advantages of low cost, small volume and small tolerance by the self-wetting layer, but also a protective sleeve is coated on the outer side of the self-wetting layer, thereby avoiding a large impact on the self-wetting layer. When the cracking is lost, the durability is improved and the service life is prolonged.
