Description of drawings
Fig. 1 is the exploded view of the butterfly brake gear of a kind of bicycle of providing of the utility model embodiment;
Fig. 2 is a driving lever and the scheme drawing that cooperates of push rod.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of butterfly brake gear of bicycle comprises braking clamp 10, and this braking clamp 10 is provided with the cavity 11 of ccontaining two brake facings 20, between two brake facings 20, is provided with reseting plate 21; Said two brake facings 20, reseting plate 21 pass the mounting hole that is located at braking clamp 10 accordingly through screw rod 22 and are installed in the described cavity 11;
Said braking clamp 10 left-hand end are to being provided with tapped bore in side brake facing 20 positions; Adjustment nut 80 is contained in this tapped bore; These adjustment nut 80 medial extremitys are connected with the brake facing 20 of this side; Be provided with the dial 70 that is used for dial changeing its rotation at these adjustment nut 80 external side ends, stir said adjustment nut 80 precessions or screw out to regulate the distance between this side brake facing 20 and brake disc through dial 70;
Establish a ball base 30 in said braking clamp 10 right-hand ends, the right-hand end 31 of said ball base 30 protrudes out outside the braking clamp and connects from the hole 12 of braking clamp 10 from left to right establishes a crank 40, and this crank 40 can drive this ball base 30 and rotate when operation; On this ball base 30, be provided with circular groove 32, be furnished with some balls 33 of pushing down by mounting ring 34 in this circular groove 32; Said crank 40 external side ends are shaped on fluted disc 41, and said crank 40 is connected with the negative thread of said ball base 30 external side ends through screw rod 42 and is fixed together with ball base 30;
The left-hand end of said ball base 30 connects a push-plate 50; Be provided with several balls between said push-plate 50 and the ball base 30; Revolving of said ball base 30 evenly is laid with several shrinkage pools on the terrace; Described ball is contained in the cooresponding shrinkage pool, and the corresponding end face of described push-plate 50 is provided with several to have towards the spin slot 51 of the inclination cambered surface of equidirectional variation, and said spin slot 51 works with shrinkage pool one said ball is clamped;
Said push-plate 50 is provided with keyway 56, set pin 55 insert said keyway 56 with said push-plate 50 and braking clamp internal connection to prevent its rotation and only can axial motion; Said push-plate 50 left-hand end are through the push rod 60 that is threaded, and said push rod 60 left-hand end are passed a back-up ring 52 backs and are connected with the brake facing 20 on right side, and retracing spring 54 is set between said back-up ring 52 and the crank 40; The screw rod body of this push rod 60 is provided with blind hole 61, and spring 62 places this blind hole 61, and driving lever 63 1 ends pass said screw rod 42, crank 40, ball base 30, push-plate 50 back cards and are inserted in the blind hole 61 of said push rod, and spring 62 is tightly pushed down; This driving lever 63 is stirred said push rod 60 adjustably and is outwards produced under external force; Said driving lever 63 other ends are equipped with a dial 64, and said dial 64 is captiveed joint with the fluted disc 41 of crank 40 external side ends.
Referring to Fig. 2; The position is provided with two shifting blocks 610 relatively on blind hole 61 inwalls of described push rod 60; The corresponding end of said driving lever 63 is provided with two plectrums 630, described driving lever 63 when rotating, thereby through said plectrum 630, shifting block 610 said push rod 60 is produced.After said push rod 60 produced part, in 62 effects of said spring down, said driving lever 63 was outwards ejected appropriate section in blind hole 61, so driving lever 63 keeps being connected with dial 64 all the time, and can under dial 64 drives, rotate.
When the utility model rotates at crank 40, drive said ball base 30 and rotate,, thereby push rod 60 is released and brake facing 20 is inwardly pushed,, play the effect of brake placing the brake disc between brake facing to compress through under push-plate 50 effects; Because crank 40 external side ends are connected with dial 64; It is when rotating; Drive said dial 64 and move in the same way, dial 64 drives said driving lever 63 homodromous movements again, thereby when push-plate 50 effect lower push-rods 60 are released; Can drive described push rod 60 simultaneously and carry out modulability and rotate and stretch out, thereby brake facing is inwardly pushed; When crank 40 resets; Though said dial 64 is homodromous movement simultaneously; But owing to only be provided with two shifting blocks 610 on said blind hole 61 inwalls; Described driving lever 63 just can not be stirred said push rod 60 again the modulability sponson is regained, and is same as this push rod 60 and only has left modulability down in driving lever 63 effects and stretch out to push the effect of brake facing, if brake facing has wearing and tearing; Then the modulability sponson of this push rod 60 will make brake facing and brake disc between distance keep basically necessarily, thereby up to good braking effect.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
