Description
Technical field
The present invention relates to that a kind of bicycle is two pushes away the disc brakes structure, relate in particular to a kind of two disc brakes structures that push away with characteristics such as assembling are simple, fabricating cost is cheap.
Background technique
Bicycle is more and more liked by the numerous common people, especially the teenager as the traffic tool of a kind of environmental protection, health.In order to improve the braking quality of bicycle, increasing vehicle or similar sports equipment have adopted the butterfly brake structure.The brake structure of this mechanical structure has reliable performance, easily makes and the many merits such as cost of production is lower.
The butterfly brake structure can be divided into push rod and bearing type according to structure.Be a kind of typical push rod butterfly brake structure as disclosed in Chinese patent 201020282440.8.It generally includes one and holds the disc embedding mouth that braking disc rotates therein; Disc embedding mouth both sides are provided with brake block, and one of them brake block can drive by the ball power plant, and the power resources of ball power plant are held up arm in rotating drawing.Like this, when brake, the operator presses parking brake, the drive wire rope rotates to draw holds up arm, draws and holds up the push rod rotation that arm drives the ball power plant, thereby make ball roll on domatic ball runway, thereby make ball base do straight line motion, thereby brake block is extrapolated, and the extruding braking disc is realized brake.Unclamp parking brake, Returnning spring drives to draw and holds up the arm backward rotation and reset, and brake block inwardly resets.The advantage such as this brake structure has that component are few, low price, assembling are simple; Its shortcoming is, during brake, the action that Returnning spring twists simultaneously and pushes is held up arm also accordingly when rotating thereby make to draw, and moves to the inside, affects the stability of its structure of tow line and the reliability of brake.
In order to address this problem, there is producer to design a kind of new structure of bearing type.The opposite side of disc embedding mouth is changed in the mounting point that is about to Returnning spring, thereby guarantees drawing when holding up the arm rotation, and its horizontal relative position keeps constant, thereby improves the stability of structure of tow line and the reliability of brake.But also there is a larger problem in it, and namely component are too much, the assembling difficulty, and cost is high.
In the brake structure of above two kinds of structures, all can adopt the ball power plant of the known various structures of present industry to drive brake block.The basic structure of ball power plant generally includes ball base and push rod, wherein is provided with 3 on ball base with domatic ball runway, and a ball or roller bearing respectively are set in the ball runway; Push rod comprises a dish section and bar section, and corresponding ball groove or symmetrical with domatic ball runway can be set in dish section, and bar section is threaded to draw and holds up arm.The industry those of ordinary skill also can make and is out of shape, with design more like structure, as long as rotation can be made among a small circle straight line motion.
In addition, also there is a common defective in above two kinds of structures, and namely in two brake blocks, only wherein a slice when brake, can tend to braking disc and move, and braking disc is shifted onto on another sheet brake block; The stroke of its braking is longer, and braking force is not enough, and structure stability is relatively poor, and the mechanical structure that can affect braking disc is stable.
Summary of the invention
