Abstract

The utility model discloses a dish of dish braking of bicycle. Through holes are arranged at the external ring surface of the contact between the disk and the braking block. Spacing according to a proper ratio is left in the clearance of the two neighboring through holes. A concave groove is arranged at the edge of the external ring surface and an inner edge hole is arranged at the edge of the internal ring surface. Most dirt and water can be removed from the braking block via the through holes and the dirt and water in dead angles can be cleaned by the concave groove and the inner edge hole so as to average the wear of the braking block and insure the sensitivity of the brake.

Description

Bicycle disc brakes disc

The utility model relates to a kind of bicycle disc brakes disc.

Although with the prosperity of vehicle today, the popularizing of automobile, still bicycle is liked for popular that deeply it not only is a walking-replacing tool, important project in the sports and competitions especially is so at the research and development of bicycle performance, also be to carry out continuously.Raising along with the bicycle performance, sensitive brake system becomes the primary equipment that improves bicycle safe naturally, and comparatively sensitive at present bicycle brake device is a disk type braking system, it is fixing installing one disc on bicycle shaft, be respectively equipped with a brake shoes in the both sides of disc outer shroud, brake shoes is controlled by brake group fixing on the vehicle frame, two brake shoes can move because of affecting of brake cable when brake, clamp disc outer shroud both sides simultaneously, the friction force that utilizes brake facing on the brake shoes and disc friction and produce, cause the wheel shaft that fixes binding with the disc center, and the front-wheel that wheel shaft drew or trailing wheel stop operating, and reach the purpose of brake.

General brake facing and disc are to be exposed to the external world, and the result who contacts with the external world for a long time, be very easy on brake facing and disc, attach dust, moisture and foreign matter, not only can cause the quick loss of brake facing thus, also can reduce the sensitivity of brake relatively, cause the danger of bicycle running to improve.So on existing disc, be typically provided with hole, reduce the area that disc attaches dust and moisture on the one hand, and when brake facing contacted with it, the hole on the disc anchor ring be able to scrape off dust and the moisture that depends on institute's contact portion brake facing.Yet because the design of hole, and fail at the contact surface of brake facing and design, remain unchanged and residual dustiness and moisture are arranged so on brake facing, still have the dead angle of part, and make the wastage rate of brake facing still higher and unequal, fail fully to reach the design objective and the effect of expection.

The purpose of this utility model is to provide a kind of bicycle disc brakes disc, dust and moisture on its scraped brake facing, so that the abrasion factor of brake facing is average, and the sensitivity of increase brake.

In order to achieve the above object, bicycle disc brakes of the present utility model has been adopted following technical scheme with disc: on bicycle disc and outer ring surface that brake facing contacts, be provided with through hole, groove and in marginal pore; This through hole is according to equidistantly being arranged in the form of a ring on the described outer ring surface; This groove is located at the outer rim of described outer ring surface; Marginal pore is located at the inner edge of described outer ring surface in being somebody's turn to do.

The beneficial effects of the utility model are: because its design mainly is that the anchor ring position that contacts with brake facing on disc is provided with through hole, and according to proper proportion on the gap of two adjacent through holes, be provided with at interval outer rim groove and in marginal pore, so when the disc anchor ring contacts with brake facing, most dust and moisture on the brake facing can be struck off by through hole, and the groove of outer rim and interior marginal pore can scrape off dust and the moisture that is positioned at position, dead angle on the brake facing, the abrasion factor of brake facing is reduced, guarantee the sensitivity that brakes simultaneously.

Below in conjunction with accompanying drawing the utility model is elaborated:

Fig. 1 is a plan sketch of the present utility model;

Fig. 2 is a part plan scheme drawing of the present utility model;

Fig. 3 is the combination generalized section of cutting open along the 3-3 line of Fig. 2;

Fig. 4 is the combination generalized section of cutting open along the 4-4 line of Fig. 2;

Fig. 5 is the combination generalized section of cutting open along the 5-5 line of Fig. 2.

See also shown in Fig. 1,3, wherein brake shoes 20 is assembled in the both sides of disc 10 nearly dish edge outer shrouds, and leans on the outer ring surface of disc 10 both sides with brake facing 22 folders that group on it is established.See it by Fig. 1, it is a plan sketch of the present utility model, on disc 10 and outer ring surface that brake facing 22 contacts average apportion be provided with a plurality of through holes 12, groove 14 and in marginal pore 16.

Cooperation Fig. 1,2 sights, through hole 12 is according to equidistantly being arranged in the form of a ring on the outer ring surface of disc 10, be provided with groove 14 and interior marginal pore 16 in the outer rim of this anchor ring and inner edge respectively again, and radially the arrangement on disc of the groove 14 on the outer ring surface, through hole 12 and interior marginal pore 16 can cover the square section of outer ring surface.

Extremely shown in Figure 5 as Fig. 3, the position that through hole 12 is offered can scrape two brake facings, 22 most contact surfaces, and the groove 14 of outer rim and in marginal pore 16 just can scrape and be positioned at 12 positions that can't contain of through hole on the brake facing 22, and make brake facing 22 and disc 10 in the process of friction, can remove dustiness and moisture on its contact surface fully.

In sum, the utility model really can be at the contact surface of brake facing and is designed, improve the shortcoming of existing brake facing and promote effect, delay the speed of the improper loss of brake facing, make brake keep sensitive, and its structure does not see existing bicycle use disc, should meet the requirement of utility application, files an application in accordance with the law.

Claims
