    A vehicle shock absorber lubrication structure includes a protective pipe and a self-lubricating layer. The protective pipe is a non-circular metal tube and includes an elongated slot. The self-lubricating layer is a layer of industrial plastic, deposited in the protective pipe and comprising a shaft hole. When the lubrication structure is placed between an outer tube and an inner tube of a vehicle damper, the protective tube engages the outer tube to prevent the self-lubricating layer from being in direct contact with the outer tube. The self-lubricating layer, with a low coefficient of friction, is mounted around the internal shaft to enable it to move smoothly relative to the outer tube.

    LUBRICATION STRUCTURE FOR VEHICLE SHOCK ABSORBER
    The present invention relates to a lubrication structure, and more particularly to a lubricating structure for a vehicle shock absorber, which structure may be formed of two components. The use of bicycles is becoming more and more popular in today's society. In order to increase the comfort of use, conventional dampers are usually placed in the front fork, the fork, or the seat tube of the bicycle to absorb the impact that is generated during use on the road, and this can provide cyclists with a buffering effect. The conventional damper comprises an outer tube, an internal shaft, a damping device, and a bearing. The internal shaft is mounted in the outer tube. The damping device is provided between the outer tube and the inner shaft, and is compressible and stretchable. The bearing is mounted between an inner surface of the outer tube and an outer surface of the inner shaft, is used for lubrication, and may be a ball bearing or a roller bearing. Then, the outer tube can move smoothly upwardly or downwardly relative to the inner shaft.
    However, the rolling cost of the conventional damper is high and its volume is large, and the bearing tolerances will influence assembly and use. If the bearing design tolerance is too small, the outer tube may not move smoothly with respect to the inner shaft, and if the bearing is designed with larger tolerances, frequency and force The impact on the bearing will increase when the conventional shock absorbs an internal force, and this will reduce the life of the bearing.
    Therefore, a conventional self-lubricating bearing is used to replace the conventional damper bearing, the conventional self-lubricating bearing being formed by an industrial plastic pipe. Since industrial plastic has characteristics of wear resistance, resistance to high / low temperatures, and low coefficient of friction, it provides advantages of low cost, small size and small tolerance. However, the structural strength of the conventional self-lubricating bearing is poor and can crack when it is impacted harder and may lose the self-lubricating effect. Then, the life of the conventional self-lubricating bearing is short and its practicality is not good. Although the structural strength of the conventional self-lubricating bearing can be increased by increasing the thickness, the advantages of the small size can be lost.
    To overcome the disadvantages, the present invention provides a lubricating structure for a vehicle shock absorber to mitigate or avoid the problems mentioned above. The main objective of the present invention is to provide a vehicle shock absorber lubrication structure which can have low friction, low cost, small size and small tolerance characteristics, and which can increase the durability and stability of the vehicle. service life of the lubrication structure.
    The vehicle shock absorber lubrication structure according to the present invention is characterized in that it comprises a protective pipe and a self-lubricating slot. The protective pipe is a non-circular metal tube and comprises an axis having an extension direction, an inner surface, an outer surface, and an elongated slot formed through the inner surface and the outer surface of the protective pipe and comprising a direction of extension identical to the direction of extension of the axis of the protective pipe. The self-lubricating layer is a layer of industrial plastic, deposited on the inner surface of the protective pipe and having a non-circular shaft hole. When the lubrication structure is placed between an outer tube and an inner tube of a vehicle damper, the protective tube engages the outer tube to prevent the self-lubricating layer from being in direct contact with the outer tube. The self-lubricating, low-friction layer is mounted around the inner shaft to allow the inner shaft to move smoothly relative to the outer tube. The lubrication structure has low cost, low volume and low tolerance characteristics, and the service life and convenience of the lubrication structure can be improved.
    The self-lubricating layer may be a layer of polytetrafluoroethylene (Teflon) formed on the inner surface of the electroplating protective pipe.
    The protective pipe may be a polygonal metal tube and the shaft hole of the self-lubricating layer may be a polygonal hole.
    The self-lubricating layer may be formed on a surface of a metal plate prior to folding the metal plate to form the protective pipe. Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description, taken in conjunction with the accompanying drawings.
    In these drawings: FIG. 1 is a perspective view of a vehicle shock absorber lubrication structure according to the present invention; Figure 2 is a sectional top view of the vehicle shock absorber lubrication structure of Figure 1; Figure 3 is an exploded perspective view of the vehicle shock absorber lubrication structure of Figure 1, placed on a vehicle shock absorber; Figure 4 is a cross-sectional side view of the vehicle shock absorber lubrication structure of Figure 3; Figure 5 is an enlarged, cross-sectional side view of the vehicle shock absorber lubrication structure at circle A of Figure 4; and Figure 6 is a sectional side view, in use, of the vehicle shock absorber lubrication structure of Figure 4.
    Referring to Figures 1 and 2, it can be seen that a vehicle shock absorber lubrication structure according to the present invention comprises a protective pipe 10 and a self-lubricating layer 11. The protective pipe 10 may be a tube non-circular metal which is bent from a metal plate, such as a polygonal metal tube. Preferably, the protective pipe 10 is a hexagonal metal pipe, and has an elongated slot 101 formed through one of the six faces of the protective pipe 10. An extension direction of the elongate slot 101 is identical to a extension direction of an axis of the protective pipe 10. In addition, two adjacent sides of the protective pipe 10 are separated by the elongate slot 101. In addition, the protective pipe 10 has an inner surface 102 and an outer surface 103, and the elongate slot 101 is formed through the inner surface 102 and the outer surface 103 of the protective pipe 10.
    The self-lubricating layer 11 may be an industrial plastic layer, and may preferably be a Teflon layer. The self-lubricating layer 11 may be deposited on the inner surface 102 of the electroplating protection pipe 10, and a non-circular shaft hole 111 is formed in the self-lubricating layer 11. Preferably, the shaft hole 111 of the self-lubricating layer 11 is a hexagonal hole. The protective pipe 10 is mounted around the self-lubricating layer 11 to protect the self-lubricating layer 11. The self-lubricating layer 11 may be formed on a surface of a metal plate before folding the metal plate to form the protective pipe 10, so that the self-lubricating layer 11 is folded into a hexagonal pipe together with the metal plate.
    In addition, the protective pipe 10 may be formed by folding the metal plate, or may also be formed by stamping a metal tube. The elongated slot 101 is formed on the stamped metal tube. In addition, the self-lubricating layer 11 may be a Teflon layer formed on the inner surface 102 of the electroplating protection pipe 10, or may be an industrial plastic layer deposited on the inner surface 102 of the protective pipe 10 by gluing.
    Referring to Figures 3-6, it can be seen that the lubrication structure of the present invention is used on a vehicle damper, and that the damper 20 comprises an outer tube 21, an inner shaft 22 placed partially in the outer tube 21, and a damping device 23 placed between the outer tube 21 and the inner shaft 22. The outer tube 21 has an internal hole 211 formed on a bottom of the outer tube 21, and the inner hole 211 may be a hexagonal hole and corresponds to a shape of the outer surface 103 of the protective pipe 10. In addition, an upper part of the inner shaft 22 is placed in the outer tube 21, and the inner shaft 22 has a shape corresponding to the shape of the shaft hole 111 of the self-lubricating layer 11. The damping device 23 is compressible and stretchable, and is placed between an inner surface of the outer tube 21 and an upper end of the inner shaft 22.
    During assembly, the lubrication structure is mounted around the inner shaft 22, and the protective pipe 10 is elastically expanded as the protective pipe 10 has the elongated slot 101 formed through the protective pipe 10 Then, the protective pipe 10 can be elastically tightened on an outer surface of the inner shaft 22 to match the dimensional tolerances of the inner shaft 22. Due to the shapes of the protective pipe 10 and the self-lubricating layer 11 which are hexagonal, the outer tube 21 and the inner shaft 22 can not rotate relative to each other. Then, the outer tube 21 can move up or down relative to the inner shaft 22 without turning, and the damping device 23 can provide a buffer effect.
    The vehicle shock absorber lubrication structure of the present invention has the following advantages. 1. Since the protective pipe 10 has the elongate slot 101 formed through the protective pipe 10, the protective pipe 10 can be elastically tightened on the outer surface of the inner shaft 22 to accommodate dimensional tolerances. of the internal shaft 22. 2. The self-lubricating layer 11 is mounted around the inner shaft 22 and is an industrial plastic layer with a low coefficient of friction, which allows the inner shaft 22 to move smoothly along the borehole. 3. The self-lubricating layer 11 is a layer of industrial plastic and has characteristics of low cost, small volume and small tolerance, and the protective pipe 10 is mounted around the self-lubricating layer. 11 to protect the self-lubricating layer 11, which prevents the self-lubricating layer 11 from cracking when it is impacted harder and increases the life and practicality of the lubrication structure.
    Although many of the advantages and features of the present invention have been set forth in the foregoing description, together with details of the structure and features of the present invention, the disclosure is for illustrative purposes only.
