Description

A kind of screw-type brake equipment for bicycle mechanical disc brake
Technical field
The invention belongs to bicycle disc brakes field, particularly relate to a kind of screw-type brake equipment for bicycle mechanical disc brake.
Background technology
Bicycle disc brakes is made up of the brake gear at a braking disc be connected with wheel and disc edge. and during brake, promote brake facing and make it clamping braking disc thus produce braking effect.At present, the mode according to braking action is distinguished, or divides with the medium of start brake facing clamping disc, and one is brake cable, and one is oil.Mechanical disc brake, to rub by the brake facing in clamp by the pulling force of brake cable and clamps disc, producing braking effect.Hydraulic disc is medium with fluid, and draw brake making piston compression fluid, pressure leads directly to clamp from oil pipe, thus promotes the piston in clamp, drives brake facing clamping disc.
In prior art, mechanical disc brake is one side brake.Namely only have while brake facing of extrapolating is exerted pressure, rubbed in disc, the brake facing of another side allows both sides all produce break-in effect after then pushing through with the disc on opposite.Its deficiency is: disc is easily out of shape, and brake facing easily weares and teares.
Hydraulic disc mostly is bilateral braking, allows brake facing clamp disc together from both sides.Its deficiency is: easily leakage of oil, regularly replace brake solution.
Summary of the invention
The object of the invention is to the above-mentioned weak point overcoming existing product, provide a kind of brake equipment for bicycle mechanical disc brake, this device can realize the bilateral braking of mechanical disc brake.
The technical scheme that the present invention realizes the employing of its object is: a kind of screw-type brake equipment for bicycle mechanical disc brake, comprise twin shaft connecting rod, described twin shaft small end has brake cable connecting portion, and brake cable connecting portion both sides are connected to the first identical armshaft of structure and the second armshaft; The lower end of described first armshaft and the second armshaft is respectively equipped with the first armshaft hole, the second armshaft hole; The first brake assemblies that structure is identical and the second brake assemblies are contained in the first armshaft hole and the second armshaft hole respectively.Described first brake assemblies comprises the first stator, the first rotor; Described first stator is nut type structure, and the first rotor is bolt type structure, and first body of bolt of the first rotor is bolted in the first screw of the first stator; First spiral shell convex surface of the first rotor is contained in the first armshaft hole.
Described second brake assemblies comprises the second stator, the second rotor; Described second stator is nut type structure, and the second rotor is bolt type structure, and bitrochanteric second body of bolt is bolted in the second screw of the second stator; Bitrochanteric second spiral shell convex surface is contained in the second armshaft hole.Point step up there is convex body in described first armshaft hole and the second armshaft hole, the first spiral shell convex surface and the second spiral shell convex surface have concave volume respectively.
Beneficial effect: the present invention is the device of one of them the driving brake sheet in bicycle mechanical disc brake pincers, and use this device to be arranged in braking clamp and can realize bilateral braking, make disc not yielding, brake facing is not easy to wear.Braking effect is good.There is the bilateral braking effect of oil pressure, oil leakage phenomenon can not occur again.Its cost is low, simple and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is STRUCTURE DECOMPOSITION schematic diagram of the present invention.
Number in the figure represents: the first stator 3, the first rotor 4, twin shaft connecting rod 5, second rotor 6, second stator 7, first screw 12, first body of bolt 13, first armshaft 14, brake cable connecting portion 15, first armshaft hole 16, second armshaft 17, second armshaft hole 18, second spiral shell convex surface 19, second body of bolt 20, second screw 22, first spiral shell convex surface 24, convex body 25, concave volume 26.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the invention will be further described.
See Fig. 1,2, a kind of screw-type brake equipment for bicycle mechanical disc brake, comprises twin shaft connecting rod 5, and there is brake cable connecting portion 15 described twin shaft connecting rod 5 upper end, and brake cable connecting portion 15 both sides are connected to the first identical armshaft 14 and the second armshaft 17 of structure; The lower end of described first armshaft 14 and the second armshaft 17 is respectively equipped with the first armshaft hole 18, armshaft hole 16, second; The first brake assemblies that structure is identical and the second brake assemblies are contained in the first armshaft hole 16 and the second armshaft hole 18 respectively.Described first brake assemblies comprises the first stator 3, the first rotor 4; Described first stator 3 is nut type structure, and the first rotor 4 is bolt type structure, and first body of bolt 13 of the first rotor 4 is bolted in the first screw 12 of the first stator 3; First spiral shell convex surface 24 of the first rotor 4 is contained in the first armshaft hole 16.
Described second brake assemblies comprises the second stator 7, second rotor 6; Described second stator 7 is nut type structure, and the second rotor 6 is bolt type structure, and second body of bolt 20 of the second rotor 6 is bolted in the second screw 22 of the second stator 7; Second spiral shell convex surface 19 of the second rotor 6 is contained in the second armshaft hole 18.Described first armshaft hole 16 and interior point of the second armshaft hole 18 step up there is convex body 25, and the first spiral shell convex surface 24 and the second spiral shell convex surface 19 have concave volume 26 respectively.
The present invention is not a complete mechanical disc brake, is the assembly of a driving brake sheet in mechanical disc brake.The present invention is metallic material.
First stator 3 and the second stator 7 are fixed in the housing of bicycle mechanical disc brake, and the first rotor 4 and the second rotor 6 inside face are fixed with brake facing respectively, and during use, braking disc is located between two brake facings.
