Description
Technical field
The present invention relates to a kind of bicycle brake device, particularly a kind of bicycle brake device that utilizes leading portion cable wire brake collocation back segment oil pressure braking.
Background technology
Bicycle is a kind of instrument of the use of advocating in the world already, and the instrument that it is not only in the motion has been the important apparatus on the stress-relieving activity also, and the development of bicycle also lives through the time of many decades, and the improvement of its structure is constantly weeded out the old and bring forth the new especially;
Especially with the brake gear of bicycle one of the main construction of Corporation R ﹠ D especially, from early stage cable wire drag mode, oil pressure till now presses mode, all shows the importance of brake structure, but above brake modes but has different good and bad points;
Existing tightwire wire disc brake apparatus and content as shown in Figure 1 to Figure 3 are general, it is to utilize the brake pull in fixed handle 10 places 11, pull tightwire wire 12 and force cam or the structure that other physical construction compressing brake shoes 14 folders end disc 15 and draw, yet approximately long 200 centimeters of this tightwire wires 12, its must curvedly be around in the bicycle body and be linked to bicycle brake handlebar 11 and front and back wheel wheel hub 16 other, therefore when the user when pulling spanner, the situation that effort can be arranged because cam or the friction force of its similar physical construction are quite large, so the feel comparatively coarse and difficult control strength of user when brake, this is its bad place; Yet the tightwire wire disc brake but is quite cheap compared to hydraulic disc brake, and tightwire wire also easily cooperates the vehicle frame size to cut, so the disc brake structure of cable type still is the general brake structure of general bicycle so far;
Another kind of well known oil pressure braking structure is to utilize to pull brake crank and the oil body in the oil pipe pushed the piston body that conducts in the general brake gear, and the brake fixture block that utilizes the principle ejection of oil pressure interlock and piston body another end interlock presss from both sides to pull and is arranged at the other disc of wheel hub, and then stops and stop tire;
This kind mode is owing to being to utilize oil pressure interlock conduction ejection mode, friction is very low between the internal system part, therefore in use feel comparative comfort and brake strength easy to control, therefore but shortcoming then is comparatively high price of expense, does not more use the oil pressure braking structure at the bicycle of low to medium price level comparatively; Moreover also be difficult for cutting owing to oil pressure pipe, also must do complete exhaust after cutting, be not easy to replace and the possibility leakage of oil, therefore often need be by the help in special car shop when installing, and so that the customer can not install easily, so still do not belong to the structure with common practicality;
Therefore, creation is artificial to solve above-mentioned shortcoming, thereby makes great efforts research and development, and joins hands to use practicality and functional brake gear in creating a kind of having concurrently.
Summary of the invention
