Description
Technical Field
The utility model relates to a brake operating means and bicycle, concretely relates to hydraulic brake operating means and highway bicycle.
Background
Road bicycles are typically provided with brake/shift operating devices on the handlebars for controlling the brake devices and the shift operating devices. Most existing mechanical brake/shift operating devices use a control cable that connects the brake/shift operating device to the brake device for braking and to the shifting device for shifting. Among them, a shift lever is generally used to operate a brake device for shifting gears. The brake lever can be used for a shift lever for pulling the shift cable, while the release lever is provided for releasing the shift cable.
Bicycling is becoming an increasingly more popular form of recreation as well as a means of transportation. In addition, bicycling has become a very popular competitive sport for amateur and professional players. Whether using bicycles for recreation, transportation, or competition, the bicycle industry is constantly improving the various components of the bicycle. In recent years, some bicycles have been equipped with bicycle hydraulic systems that primarily include a hydraulic operating mechanism and a hydraulic actuating component.
In the existing hydraulic brake operating device for bicycles, especially in road bicycles, a hydraulic operating mechanism is integrated in an operating handle and is very close to the rotation center of a speed change operating unit (located above the horizontal plane where the rotation center of a brake operating lever is located), and many speed change operating parts are arranged around the rotation center of the speed change operating unit, so that the existing hydraulic brake operating device occupies a large space and has a very complicated structure.
