Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to a rim of a bicycle. [Prior Art] Modern people emphasize health and leisure 'many people will travel on a bicycle in the holiday of the continent'. Because of the current oil price and the greenhouse effect, there are more and more people responding to green bicycles as commuters to work and school. . In view of this, the safety of riding a bicycle must be taken more seriously. In the bicycle components, the 'excellent performance (four) car system not only improves the sportiness, but also ensures the safety of the king. - The commonly used bicycle brake system can be divided into two types of spurs and disc brakes. The 'skin' (four) is widely used because of its light weight and low unit price. Moreover, the clip brake is decelerated by friction between the brake pad and the brake side of the rim. In the case of long and steep continuous downhill sections, the friction between the brakes and the brakes of the rims produces high temperatures, which may cause the wheels to be wounded and difficult. In severe cases, the risk of tire bursting or brake failure may occur. Therefore, in addition to improving the existing brake pads, how to provide a kind of high-temperature and wear-resistant self-wheels is also an urgent problem to be overcome in the industry. SUMMARY OF THE INVENTION The object of the present invention is to provide a bicycle rim for solving the above problems. The t, the display has two corresponding brake edges, the outer edge of the car edge: a fluoroplastic layer' and the material of the fluoroplastic layer is selected from polytetraethylene, terpene propylene, and fluoride. a component of the group consisting of a compound, an ethylene, a tetraethylene ethylene copolymer, and a core material thereof. Furthermore, the fluoroplastic layer is more mixed with titanium metal. The outer edge of the brake rim of the bicycle wheel of this month has a fluoroplastic layer' which can effectively alleviate the high temperature caused by excessive friction, thus increasing the stability of the self-scheduled car brake system and improving the safety of the bicycle. . [Embodiment] The present invention provides a bicycle rim that is resistant to high temperatures and wear. Please refer to .® 1 ' Figure 1 is a perspective view of the rim of the present invention. The bicycle wheel 1 has two corresponding braking edges 10, and the braking edge 10 is used for the frictional friction with the brake pads (not shown) of the clamping brake system to achieve the effect of deceleration. Moreover, the outer edges of the two brake edges 10 respectively have a fluoroplastic layer 20. ❿ Next, please refer to FIG. 2A, FIG. 2B and FIG. 3 at the same time, and the figure is a perspective view of the rim of the rim, and the rim of the rim shown in FIG. 2B has a gas plastic 曰 20 and FIG. 3 is Figure 2B is a cross-sectional view of the rim. In the present embodiment, the city 1 has a groove U' on the side 10 and the fluoroplastic layer 2Q is embedded in the groove 11. The towel 'fluoroplastic layer 2G' is fixed to the brake side 10 by a method such as sintering, electrostatic spraying or powder bonding resin. In the present embodiment, 'the fluoroplastic layer 20 is intended to be inside the groove u of the brake side'. However, those skilled in the art may also have the knowledge as shown in the ® 4 and (4) the side of the car 1〇6 1329577 The step is 11⁄2 in order to apply the fluoroplastic layer 2〇 to the entire outer edge of the brake rim. In the present invention, the material of the fluoroplastic layer is selected from the group consisting of polytetrachloroethylene, aerobics, a mixture of ethylene-tetrafluoroethylene copolymers and mixtures thereof. The above-mentioned fluorine is converted to a coating having a rim brake side because it has excellent heat resistance and low friction. Furthermore, the fluoroplastic φ a of the present invention may be blended with titanium metal to enhance its strength and high temperature performance. In the fluoroplastic layer on the brake side, it is preferred to use polytetraethylene as its polytetrafluoroethylene type - a kind of artificial sub-material which replaces all hydrogen atoms with fluorine by the fluorine 'Because of the polytetrafluoroethylene The fluorine atom will cover the carbon bond, and the carbon bond has a high stability, so the gas-containing outer shell of the polytetrafluoroethylene molecular shape has a lower friction coefficient and wear resistance.

For the rim of the uncoated fluoroplastic layer, the brake side surface coated with the fluoroplastic layer is low, and the result is changed due to the beneficial opening of the fan. Therefore, after the above description is disclosed, those skilled in the art can find that the coating of the fluorine layer on the outer edge of the car can significantly improve the resistance to high=, thereby improving the temperature of the rim caused by continuous braking. Too high a question "Second: Γ't invented the bicycle rim because it is coated with a fluoroplastic layer and has the wear and tear of the car's good fortune and the temperature performance, so it can effectively reduce the situation of the south temperature when the car is 2 Therefore, the stability of the bicycle clip brake system is increased, and the safety of the bicycle is ensured.升 1329577 [Simple description of the drawings] Fig. 1 is a perspective view of the rim of the present invention. 2A and 2B are partial perspective views of the rim, and the rim of the rim shown in Fig. 2B has a fluoroplastic layer on the side of the brake.
