Motorcycle linking brake
Technical field
The present invention relates to a kind of motorcycle brake device, particularly a kind of motorcycle linking brake.
Background technology
Existing motor bike adopts the preceding wheel brake of hand shift usually, foot control system rear wheel brake structure, but people's psychology and Physiologic Studies show: under emergency, people tend to subconsciously " using both hands and feet ", and human motion physiology and human factor engineering studies show that: the responsiveness of hand is 1.5 times to 3 times of pin, the actual result that motorcycle brake is moved is that preceding wheel brake is early than rear wheel brake so " use both hands and feet ", thereby cause motor bike to be tumbled, as for people in case of emergency, cause overturning of common occurrence especially because of lose one's head stop again trailing wheel or the front-wheel of only the stopping misoperations such as (rear wheel brake do not tramp with one's feet) of front-wheel of stopping earlier of anxiety.
Also the someone adopts linking brake, for example Chinese utility model patent 94245827.3, on April 10th, 1996, bulletin was authorized, a kind of motorcycle brake structure, comprise right handgrip, preceding wheel brake backguy, stretcher, rear wheel brake backguy, its preceding wheel brake backguy is divided into upper and lower two sections backguys, at the backguy connecting panel that is provided with of upper and lower section backguy, connects a middle brake backguy between this backguy connecting panel and stretcher.And for example Chinese utility model patent 99217787.1, on October 11st, 2000, bulletin was authorized, a kind of double acting motorcycle brake device, on this motorcycle brake device, a pull bar only is set, and on pull bar, be installed with a moving part, and priming rope before being consolidated with between the preceding hill holder of wheel brake before this moving part and the control, then be consolidated with back priming rope between hill holder after this moving part and the control rear wheel brake, when making this pull bar be spurred and drive moving part to move, hill holder produces brake to front and rear wheel simultaneously with the back hill holder before can drawing respectively.Above-mentioned two patents all are to adopt hard coupling assembling to realize interlock in essence, if front and back wheel brake play motion inconsistent (in fact also being difficult to accomplish in full accord), stopped when dead as a wheel, the another wheel is not brake also, the brake backguy just is tightened up stuck, and the interlock brake also just loses meaning; The order problem of wheel brake and rear wheel brake before above-mentioned in addition two patents are also considered can not solve effectively that the front-wheel of stopping is earlier stopped trailing wheel again and the safety performance problem that causes overturning.
Summary of the invention
Technical matters to be solved by this invention provides a kind of motorcycle linking brake that braking effect is good, safety performance is good that links, no matter be hand action earlier or pin action earlier, Sha Che trailing wheel always at first, thereby the generation of the misoperation of avoiding fully braking has been eliminated because of misoperation and has been caused the hidden danger of tumbling.
For solving the problems of the technologies described above, the present invention is by the following technical solutions: a kind of motorcycle linking brake, comprise the front-wheel brake, front-wheel brake steel wire rope, foot-operated fork, pull bar, stretcher, the trailing wheel brake, pipe link, manual fork, trailing wheel brake steel wire rope, handgrip, described foot-operated fork is provided with rotating fulcrum, one end of front-wheel brake steel wire rope links to each other with the front-wheel brake, the other end of front-wheel brake steel wire rope links to each other with an end of foot-operated fork, the other end of foot-operated fork links to each other with an end of pull bar, the other end of pull bar links to each other with stretcher, one end of described manual fork is provided with rotating fulcrum, manually the other end of fork links to each other with an end of trailing wheel brake steel wire rope, the other end of trailing wheel brake steel wire rope links to each other with handgrip, one end of pipe link links to each other with the trailing wheel brake, the other end of pipe link links to each other with the swinging end of manual fork, be provided with the interlock Flexible Connector between foot-operated fork and the manual fork, the front-wheel brake is reserved certain differential brake idle travel of front and back wheel.
Described interlock Flexible Connector can be arranged to: comprise roll adjustment pull bar, compression spring, the upper end of roll adjustment pull bar links to each other with the pull bar coupling end of foot-operated fork, the swinging end of described manual fork is provided with through hole, the through hole of manual fork is passed and the below of the movable pendulum bar that reaches in the lower end of roll adjustment pull bar, is provided with compression spring between the lower end of roll adjustment pull bar and the manual fork.
Described interlock Flexible Connector also can be arranged to: comprise roll adjustment bar, extension spring, the upper end of roll adjustment bar is connected with the pull bar coupling end of foot-operated fork, one end of extension spring is connected with the lower end of roll adjustment bar, and the other end of extension spring is connected with the swinging end of manual fork.
Described interlock Flexible Connector can also be plate spring or torsion spring, and an end of plate spring or torsion spring is connected with the pull bar coupling end of foot-operated fork, and the other end of plate spring or torsion spring is positioned at the below of manual fork.
In the technique scheme, manually control rear wheel brake, because the action of hand than very fast, obviously than fast with the brake of foot control system trailing wheel brake, therefore can improve the safety of emergency brake with hand shift trailing wheel brake; Owing to be provided with the interlock Flexible Connector between foot-operated fork and the manual fork, starting the movable pendulum bar by the spring band in the interlock Flexible Connector when foot-operated fork rotates rotates, thereby coordinated control trailing wheel brake action, because spring has elasticity, even if trailing wheel is stopped after death, foot-operated fork still can continue swing until thoroughly checking front-wheel, therefore can avoid braking also with regard to ineffective problem with regard to being tightened up stuck the interlock because of the brake backguy in the prior art, has improved the interlock braking effect; And because the front-wheel brake is reserved certain differential brake idle travel of front and back wheel, no matter be hand action earlier or pin action earlier, always Sha Che trailing wheel at first, so generation of the misoperation of can avoiding fully braking has been eliminated because of misoperation and has been caused the hidden danger of tumbling.
