Abstract
The utility model relates to a brake device for a bicycle, which is the improvement of the brake mechanism for the brake cable of the bicycle, and the sensitivity and the reliability of the brake are enhanced. The utility model makes a brake pull cable divided into two sections which transfer the brake force together with a bridle ring and a connecting frame, and makes one section pull cable distributed at both sides of a wheel and connected with a swing plate by using the bridle ring. The swing plate is rotated by winding a support shaft and nears the wheel to finish the brake action under the function of the brake force. The utility model has the advantages of compact structure, convenient installation and adjustment and smooth force transmission, avoids the phenomena that the brake is out of order and the joint of the brake pull cable is broken, and enhances the safety of the driver.
Description
The utility model is the brake gear about bicycle, is the improvement to the manual brake gear of bicycle.
At present, bicycle both domestic and external (hereinafter to be referred as car) no matter be the car of which kind of trade mark, is said for brake, has only the branch of rim brake and backpedalling brake.Rim brake divides cable brake and pull bar lock again.The cable brake structure of current use is connected Change-over frame between brake backguy (hereinafter to be referred as backguy) and brake rubber block, so that two brake rubber blocks are distributed in rim both sides, and are delivered to brake rubber block with brake weight, make car braking.Change-over frame is made up of two pincerlike framves, by point device on car justice.The radial structure of backguy is two-layer, and one of its end points is connected with vehicle frame with the car wisp, and the ectonexine of other end is separately fixed on the contact of two pincerlike frame homonymies.During application of force brake, utilize the principle of work power of hand vice to be delivered on two pincerlike framves by the backguy ectonexine, make it do rightabout rotation around fulcrum, then the brake rubber block of other end device contact rim is finished braking.Draw and press because the application of force is internal layer and the skin to a backguy, affect two pincerlike framves to do rightabout rotation, make brake rubber block contact rim.The deformation that produces in the manufacturing errors of backguy, the assembly error of brake gear, the car use all can influence the pressure of two brake rubber blocks to rim, thereby brake failure often occurs or the backguy joint cut-offs phenomenon.Antagonistic force in the brake process is also by backguy effect application of force person simultaneously, and feel is to uncomfortable.
The purpose of this utility model is to improve the sensitivity and the reliability of cable brake brake.
The brake gear of bicycle is made up of backguy, Change-over frame, spring, brake rubber block and tightening screw, it is characterized in that:
A. a wheel has two sections backguys, and epimere is fastened between bicycle wisp and the bridle ring, and hypomere is by the guiding of bridle ring and track adjusting wheel, and its end is fastened on respectively on two oscillating decks.
B. Change-over frame is by the geometrical clamp that has the fulcrum and the axis of guide, the oscillating deck that has hole and gentle moving axis, track adjusting wheel and spring are formed, the hole of oscillating deck and fulcrum running-fit, brake rubber block and gentle moving axis are fastening, and geometrical clamp and bicycle car justice are fastening, and torsion spring set is on fulcrum, the one end acts on the geometrical clamp, and the other end acts on the block of oscillating deck.Track adjusting wheel is enclosed within on the axis of guide.
When the application of force is braked, bridle ring is mentioned in backguy between car wisp and the bridle ring, driving the hypomere backguy affects two oscillating decks to rotate towards the wheel movement direction around fulcrum respectively, the brake rubber block that is fastened on the gentle moving axis is close to rim, part away from fulcrum contacts with rim earlier, because the hole of gentle moving axis and oscillating deck is to closely cooperate, under the friction force effect that produces between contacted brake rubber block and the rim, gentle moving axis drives the opposite wheel movement direction of brake rubber block and rotates, brake rubber block and rim area of contact are increased, friction force is that braking force also increases thereupon, until brake wheel.Hand discharges the car wisp, and under the torsion spring effect, oscillating deck and brake rubber block all reset.
The utility model has the advantages that: when waiting to brake the application of force, the epimere backguy only do upward to motion, do not made and various error effects such as installation; And hypomere backguy unsteady putting in bridle ring, its length can be adjusted freely; Fulcrum is to the distance (OA) of rim brake lining, cross the distance (OB+BC) of brake rubber block driving surface less than fulcrum by gentle moving axis (OB) to the rim brake lining, guarantee that fully brake rubber block holds rim tightly, (value 30～45 degree of fulcrum to the vertical line (OA) of rim brake lining and fulcrum to the angle (α) of gentle moving axis line (OB) for Cui) have improved the reliability that brakes; Simultaneously, fulcrum and oscillating deck are that bearing fit, bridle ring and track adjusting wheel are that the motion of backguy motion guide, brake rubber block is to the wedging of axletree sense of motion, and the α angle reduces, and have improved the sensitivity of brake; Antagonistic force in the brake acts on the car justice by fulcrum, and application of force person does not have uncomfortable sensation.
