According to the present invention, the brake pad portions 16b and 16c are made of different friction materials, so that they have different braking characteristics, for example, one is suitable for dry conditions, and the other is suitable for wet conditions: while the leading edge The pseudo 16a of the brake pad part is formed by a long wear-resistant compound, and its friction is lower than that of 16b and 16c. Its friction is so low that the lining can slip, so that the bicycle will not produce when braking. The grip, vibration and squeal produced by the conventional brake pads. The low friction lining section 16 a is provided at the front end of the brake lining, so that the green wheel of the bicycle rotates into the low friction liner section. The composition of the low friction part 16 a is generally rubber or compound elastomer, so that when it slides along the wheel line, the edge of the pad part will not grip the rim and cause vibration and cries. Because there is no grip and vibration Therefore, the liner portion 16 b with a high degree of sharpness at the back can controllably contact the rim. The pad portion 16b may have a lower friction than the portion 16c. Although this is not necessary, the friction of the portion 16b is greater than the portion 16a, and, if necessary, it may be a transitional liner to further prevent Grip emblem pad 16c by gripping or shaking. The brake pad portions 16a and 16b are separated by the first V-shaped groove 21, and the portions 16b and 16c are separated by the second V-shaped groove 22, the V-shaped groove 22 contributes to the dispersion of thick gas or rain In addition to the same effect, the first V-shaped groove 21 also has the elastic bending of the rib portion 20a, so that the front brake pad 16a is in contact with the rim but deviates for some reason, it can still be maintained at Connection _-The standard of this paper is applicable to Chinese National Standard (CNS) Α4 specification (21〇 > < 297mm) -------- f installed ------ order 丨 ---- 7 瘃-(Please read the precautions on the back before filling out this page) Printed by the Ministry of Economic Affairs, Central Bureau of Economic Development, Beigong Consumer Cooperative, printed by the Ministry of Economic Affairs, Shaoyangti, Prefectural Bureau, Zhengong Consumer Cooperative.

As shown in FIG. 1, after molding, the contact surfaces of the brake pad portions 16b and 16c lie on a common plane indicated by the solid line 30, which is like a plane that contacts the bicycle rim. Due to the elastic bending provided by the tongue portion 2〇a and enhanced by the groove 21, the free end of the low friction pad portion 16a. That is, the front edge of the portion 16a can extend below the solid line 30, It is used to make the pad 16a control the grip, bag movement and screaming phenomena during the initial low friction friction. Part 16a can also be used as a cleaner to remove dirt, water and other impurities from the rim to avoid contamination of brake pad parts 16b and 16c. In other words, the low-friction brake pad portion 16a will first contact the rim with low friction to control grip, vibration, and barking. Subsequently, the elastic means provided by the tongue portion 20a of the back bone 20 will bend so that the high-friction brake pad portion 16b can contact the rim to stop the bicycle. Therefore, this brake lining can provide a more effective and quieter braking function. Since the flexible brake pad portion 16a is made of a wear-resistant material and contacts the rim with low friction, the wear will be lower than that of the higher friction pad. In addition, since there is no phenomenon of grip and vibration, the wear of the brake pad portion 16b will be less. For example, the material constituting the pad portion 16b has a high friction brake function, and can be selected to suit different occasions, such as wet weather, dry weather, or racing. As shown in FIG. 1, the pad portions 16b and 16c occupy a larger portion of the pad 16 and have a lower surface. When in contact with the rim, their surfaces are coplanar, as shown by the solid line 30, so they can be in contact with the meshing of the rim at the same time-8--This paper size is applicable to the Chinese National Standard (CNs) A4 specification (210X297 mm ) --------- f outfit ------ order ----- 4 Shu (please read the precautions on the back before filling in this page) V.

It should be understood that more than two such pad parts can also be used to contact the rim at the same time ° The pad with only one compound or component has a disadvantage 'it cannot be used simultaneously in thick and dry weather Braking smoothly * It also can't control squeaking, gripping, clearing the rim. A single compound brake pad lining can only be used in a single situation. According to the present invention, the partitioned bellows composed of pre-selected rubber compound or elastomer compound has multiple functions. The front part of the lining is made of a low-friction compound. When it touches the input edge, Keco slides to keep the brakes smooth, so that the high-friction pad part at the back avoids scratching the house, vibration and noise when it touches the rim. And other phenomena. A special compound is used for the rear emblem pad part, so as to have the best function under wet and dry braking conditions or when racing. Printed by the Employees Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) The compounds used for the front brake emblem pads include rubber or elastomer substrates and materials such as clay or graphite Filling agent. The high friction compound that controls the brake function uses materials such as silicon dioxide, iron dioxide, or other wear-resistant materials as a ballast. Various compounds are molded into the desired shape and cured by heating, or connected together to form an integral separation liner. Different compounds can be marked with different colors to indicate different braking characteristics. —9 — The size of this paper is suitable ^ China National Standard (CNS) Α4 is now available (210X297mm) " Printed by Beigong Consumer Cooperative of the Central Standardization Bureau of the Ministry of Economic Affairs 〇C7 D7 5. Creation Instructions In the brake pad assembly shown above, the different partitions can be composed of different components, each of which provides various functions required for braking. The front lining is made of low friction compound. Composition, used to control vibration, grip and scream. Although the present invention has been shown and described with preferred examples, it should be understood that various other modifications can be made within the spirit and scope of the present invention.
