Abstract
The invention discloses a brake linkage mechanism. The brake linkage mechanism is arranged at an appropriate position of the body of a bicycle by a fixing seat, so that the brake linkage mechanism can be simultaneously connected with brake cables of front and back wheels, wherein the fixing seat is provided with a first connecting part and a second connecting part. The linkage structure is arranged in the mounting part and is composed of at least three disc bodies, wherein the peripheries of the three disc bodies are provided with guiding parts which are used for being connected with brake cables introduced from handlebars and being connected to the brake cables of the front and back wheels. By the rotating connection of the three disc bodies of the linkage structure, front and back brakes can act simultaneously, thereby ensuring uniform braking force on the front and back wheels so as to avoid crash. Because the linkage structure is designed by diameter designs of the three disc bodies, the braking force on the front and back wheels can be adjusted, thereby being capable of generating the braking force different from the preset braking force on the front and back wheels.
Description
Technical field
The present invention relates to a kind of brake linkage mechanism, a kind of bicycle that provides is provided while interlock front and back wheel line traffic control presss from both sides the brake linkage mechanism of stopping.
Background technology
Bicycle structure as shown in Figure 1, because the modern is to the attention of health and carbon reduction idea, bicycle forms motion gradually in conjunction with the instrument of riding instead of walk, though be go on a tour on holidays, athletic competition or the working etc. of travelling frequently, increasing personage begins to choose more advanced bicycle and drives; Therefore, the development of bicycle body more and more designs faster towards driving the speed of reaching in lighter labour-saving mode, therefore in light weight and the bicycle of multiscale such as the bicycle of highway car or functional orientations such as mountain-climbing car or folded bicycle are just form main flow on the specification gradually.
And along with the velocity limit that drives of bicycle is accelerated, brake system also is particular about the brake power more, to satisfy the safety under running at high speed, the present bicycle brake system line traffic control folder that mainly the is divided into traditional type system of stopping, and the comparatively high disc brake system of cost, no matter but be that folder is stopped or the structure of disc brake, present brake still with the plug in car handle on the handle of left and right both sides respectively to the front and back wheel control of braking, by Front brake 1 and back 2 positions that are installed in bicycle of braking as can be known among Fig. 1.
So when bicycle drives; no matter highway car that it drives at a high speed on highway or the mountain-climbing car that drives in cross-country bumpy sections; no matter also stop or the disc brake structure for folder; the general mostly unlikely generation of controlling has other dangerous situation; yet when running at high speed or descending when spurt; if this moment, the rider ran into emergency (as obstacle; metal road and when dodging vehicle); the rider through the reflexive Brake lever of holding of regular meeting to make anxious action of stopping; when making emergency brake because of a brake power inequality of taking turns wherein; or when operation its front and back wheel brake application of force difference cause single brake power of taking turns to cross low or overweight (comparatively serious with front-wheel especially); the accident generation that causes stall or center of gravity beat and fall car; the lighter is injured; weight person is even cause more serious actual bodily harms such as fracture; dead or fall car after produced by the unfortunate situation of overtaking collision; therefore after pursuing the brake power, how making the safety lifting of emergency brake is an emphasis that should improve immediately.
See also Fig. 7 and Fig. 8, therefore be easy to generate the problem of falling car in view of independent control front-wheel or rear wheel brake, the part technology just develops the structure that with the two-wheeled synchronous brake, can effectively reduce the probability that car is fallen in single-wheel stall by the two-wheeled synchronous brake, though the needs that synchronous brake can't provide part to drive as special action such as stunt, but actual driving, really be safe form with synchronous brake, therefore just have the dealer to develop can two-wheeled to move simultaneously the synchronous brake structure (as No. the 590098th, TaiWan, China patent) of brake, the principal feature of this structure design is:
This synchronous brake structure is for being installed in the leading front end of bicycle with a body 4, this body interior offers two sprues 402 and two secondary channels 401, one end of each runner is provided with joint 43 respectively at upper end and lower ending opening position group, and wear respectively and penetrate brake cable 10/20/A/B and enter and connect it and place two active pistons 41 and two passive pistons 42 in each sprue 402 and the secondary channels 401, wherein the body of rod middle section of these two active pistons 41 respectively offers annular groove and sprue 402 inner edges formation ring-type compression space 404, and the body of rod middle section of two passive pistons 42 respectively offers annular groove and secondary channels 401 inner edges form ring-type compression space 403, and all offers a through hole 405 between the tube wall of two sprues 402 and two secondary channels 401.
So, when brake cable A/B when brake is carried out in the tension of the Brake lever place of upper end, these two active pistons 41 are in the 404 upwards starts of ring-type compression space, make the liquid that is present in ring-type compression space 404 in the ring-type compression space 403 of through hole 405 channelling to the secondary channels 401, force the ring-type compression space 403 of two passive pistons 42 in two secondary channels 401 upwards to raise, and then drive brake cable 10/20 is pulled upwardly and then make brake cable 10/20 other end to carry out brake in the brake structure 1/2 of front and rear wheel respectively.
Yet this existing structure has following shortcoming:
1. the body 4 that with the piston is action merges other aforementioned part and liquid, will inevitably have cooresponding volume and weight, will form the burden that reaches on the weight on the volume for the design agitation of stressing light and handy bicycle.
2. by the design of two sprues 402 and two secondary channels 401 and two active pistons 41 and two passive pistons 42, perhaps accurate in the action, but complex structural designs and maintenance difficult are its shortcoming.
Summary of the invention
The present invention is directed to the shortcoming of above-mentioned prior art, a kind of brake linkage mechanism is provided, this brake linkage structure construction is simple, applicability is strong.
