Abstract
The utility model discloses a brake of a bicycle, which belongs to the technical field of braking devices. The utility model comprises a housing, and the housing is provided with a lever. The inner part of the housing is also provided with a braking mechanism controlled by the lever, and the housing is also provided with a pillar which is provided with a screw hole which penetrates through the pillar. The pillar is connected with a regulating screw through the screw hole, and the axle center of the regulating screw is provided with a through hole. A core wire of a braking wire penetrates through the through hole and is connected with the tail end of the lever, and an outer covering wire of the braking wire is matched with the mouth part of the through hole and is clamped at the mouth part of the through hole. The braking wire between the lever and the pillar is sheathed with a reset spring. The utility model can carry out coarse regulation and can also carry out fine regulation by the regulating screw. The utility model has the advantages of convenient regulation and reliable use. The utility model can be applied on bicycles and can also be applied on electric bicycles.
Description
Technical field
The utility model relates to a kind of vehicle braked device, particularly a kind of and vehicle Fu brake equipment.
Background technology
The servo-actuated drg of Electrical Bicycle of the prior art, comprise housing, housing is provided with tommy bar, also be provided with braking mechanism in the housing by described tommy bar control, be fixed with a catch in the bicycle body, catch is provided with a hole, and the heart yearn of brake cable passes this hole and is connected with tommy bar, the edge of outer envelope curve conflict circular hole on catch of brake cable is set with retracing spring on the brake cable between tommy bar and the catch.During actual the use, the brake lever of car is connected with the heart yearn of brake cable, need glancing impact, hold tight brake lever, the outer envelope curve of brake keeps motionless, and it is axially incompressible, can play a supportive role to the brake heart yearn, thereby can be by brake heart yearn pulling tommy bar, tommy bar drives the braking mechanism action that is arranged in the housing, realizes braking.In use, the brake heart yearn can elongate gradually owing to elastic deformation, and the tommy bar rotational angle is diminished, braking effect reduces or loses braking potential, for this reason, need tighten up the brake heart yearn, when tightening up the brake heart yearn, need unclamp the connecting bridge of tommy bar and brake heart yearn, fix again behind the pulling heart yearn, this regulative mode regulated quantity is big, operation inconvenience, be difficult to finely tune, the structural strength of catch is poor, influences the reliability of service of drg.
The utility model content
The purpose of this utility model provides a kind of drg of bicycle, makes it easy to adjust, uses reliably, can finely tune.
The purpose of this utility model is achieved in that a kind of cycle brake, comprise housing, housing is provided with tommy bar, also be provided with braking mechanism in the housing by described tommy bar control, also be provided with a pillar on the housing, pillar is provided with the tapped bore of consistent perforating branches post, pillar connects an adjusting screw(rod) through described tapped bore, the adjusting screw(rod) axle center is provided with a through hole, the heart yearn of brake cable passes through hole and is connected with the tommy bar tail end, the outer envelope curve of brake cable matches with the through hole oral area and is stuck in the through hole oral area, is set with retracing spring on the brake cable between tommy bar and the pillar.
When the utility model uses, the brake lever of car is connected with the heart yearn of brake cable, need glancing impact, hold tight brake lever, the outer envelope curve of brake keeps motionless, and it is axially incompressible, can play a supportive role to the brake heart yearn, thereby can be by brake heart yearn pulling tommy bar, tommy bar drives the braking mechanism action that is arranged in the housing, realizes braking; Unclamp brake lever, under the effect of retracing spring and braking mechanism antagonistic force, tommy bar resets; When needs are regulated brake cable, can be the same with prior art, unclamp the connecting bridge of tommy bar and brake heart yearn, fix again behind the pulling heart yearn, can carry out coarse regulation; Also can rotate adjusting screw(rod), promote the outer envelope curve of brake heart yearn and brake to produce relative motion between the heart yearn, realize elongating or shortening the effective interaction length of brake heart yearn, can overcome the problem that the elongation of brake heart yearn brings the braking effect difference, the mode of this employing threaded adjusting can realize fine setting; Pillar is arranged on the housing, can make structure more stable, easy to adjust, and structural strength is good; This use is novel can be applied on the bicycle, also can be applied on the Electrical Bicycle.
For adjusting screw(rod) and pillar after the adjusting are fixed well, be difficult for getting loose, described adjusting screw(rod) is provided with a jam nut.Unclamping nut can regulate adjusting screw(rod), screws nut after having regulated itself and pillar are compressed, and can prevent that adjusting screw(rod) from getting loose.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 housing, 2 tommy bars, 3 heart yearns, 4 retracing springs, 5 pillars, 6 jam nuts, 7 adjusting screw(rod)s, 8 outer envelope curves.
The specific embodiment
As figure, a kind of cycle brake, comprise housing 1, housing 1 is provided with tommy bar 2, also be provided with braking mechanism in the housing 1 by described tommy bar 2 controls, also be provided with a pillar 5 on the housing 1, pillar 5 is provided with the tapped bore of consistent perforating branches post 5, pillar 5 connects an adjusting screw(rod) 7 through described tapped bore, adjusting screw(rod) 7 axle center are provided with a through hole, the heart yearn 3 of brake cable passes through hole and is connected with tommy bar 2 tail ends, and the outer envelope curve 8 of brake cable matches with the through hole oral area and is stuck in the through hole oral area, is set with retracing spring 4 on the brake cable between tommy bar 2 and the pillar 5; Adjusting screw(rod) 7 is provided with a jam nut 6.
When the utility model uses, the brake lever of car is connected with the heart yearn of brake cable 3, need glancing impact, hold tight brake lever, the outer envelope curve 8 of brake keeps motionless, and it is axially incompressible, can play a supportive role to heart yearn 3, thereby can be by heart yearn 3 pulling tommy bars 2, tommy bar 2 drives the braking mechanism action that is arranged in the housing 1, realizes braking; Unclamp brake lever, under the effect of retracing spring 4 and braking mechanism antagonistic force, tommy bar 2 resets; When needs are regulated brake cable, can be the same with prior art, unclamp the connecting bridge of tommy bar 2 and brake heart yearn 3, fix again behind the pulling heart yearn, can carry out coarse regulation; Also can unclamp jam nut 6, again adjusting screw(rod) 7 is regulated, rotate adjusting screw(rod) 7 during adjusting, produce relative motion between the outer envelope curve 8 of promotion heart yearn 3 and the heart yearn 3, realize elongating or shortening the effective interaction length of heart yearn 3, can overcome the problem that heart yearn 3 elongations bring the braking effect difference, screwing jam nut 6 after having regulated compresses itself and pillar 5, can prevent that adjusting screw(rod) 7 from getting loose, the mode of this employing threaded adjusting can realize fine setting.
