Description
Technical field
The present invention relates to bicycle art, more particularly to a kind of wheel rim with brake side.
Background technology
Bicycle is common walking-replacing tool in people's daily life, and which is cheap, easy to maintenance, easy to use, deep
Liked by the people of other countries, define huge bicycle consumption market, with the very fast development of modern society, bicycle is
Not exclusively traffic and means of transport, with several functions such as collection body-building, tourism, contests.The height of bicycle class depends on
In selection and the workmanship of material.Typical basic, normal, high shelves Bicycle Frames are respectively by carbon steel, chrome molybdenum and aluminium alloy and carbon
Fiber is manufactured.Carbon fiber is a kind of new composite, and it has the advantages that, and lightweight, specific strength is high, specific stiffness is big, and is had
There are designability and formability, so that the structure of design has higher structure efficiency.
Because carbon surface is weaker at wear-resisting aspect, fiber is easily damaged or is ruptured, therefore, can add and use glass fibers
Dimension, quartz glass, are improved anti-wear performance.But carbon fiber rim needs to use releasing agent, the demoulding in the demoulding
Agent causes friction subsurface power low, this easy demoulding, but this also causes the braking quality on top layer not good.Further, since a variety of causes,
The brake lining of these fiber wheel rims is typically plane, and which is weaker in terms of brake, especially in the presence of having water.
The content of the invention
It is an object of the invention to provide it is a kind of with brake side wheel rim, it is above-mentioned present in prior art to solve
Problem.
The technical scheme that the present invention is provided is as follows：
A kind of wheel rim with brake side, including tire joint portion, which is located at the outside of the radial direction of wheel rim；Spoke is combined
Portion, which is located at the inside of the radial direction of wheel rim；First side positioned at wheel rim, between tire joint portion and spoke joint portion first
Side and second side, it is characterised in that first side and second side are provided with brake side, and described brake side includes multiple
The boss on first side and second side surface is protruded from, boss height is 0.2-3 millimeters, the gap between boss and boss is
0.5-5 millimeters.
In preferred embodiment, boss height is 0.2-3 millimeters, the width of boss circumferencial direction is 3-25 millimeters, convex
The radial dimension of platform is 3-25 millimeters, the gap between boss and boss is 0.5-5 millimeters.
In preferred embodiment, the boss can be circle, prismatic, trapezoidal, triangle or fan ring.In other reality
Apply in example, can also be other shapes.
Above-mentioned boss, preferably circumferentially single repeated arrangement, or two kinds of boss are spaced.
Seen from the above description, the invention provides a kind of wheel rim with brake side, the wheel rim has the following advantages：
1st, described brake side includes multiple boss for protruding from first side and second side surface, and boss height is
0.2-3 millimeters, the gap between boss and boss are 0.5-5 millimeters.Therefore, the boss has four direction Brainage boundaries, draining energy
Power is bigger than ordinary construction or special drainage channel structure, when quick Fabrication is acted on can quick emptying water quality, thus can have
Effect reduces impact of the moisture film to frictional force.
Present invention brake side structure, the water quality that boss is discharged can effectively depart from boss surface, ordinary construction or general band
The product of discharge structure, the water quality of discharge make surface cover again last layer water because flowing back brake area surface on same surface
Film, and boss structure is because of many one layer of steps, discharges water quality and will not flow back boss surface.
The condition product test checking such as pass through：Wet braking distance can shorten 20-30%, reach dry type braking distance
90%, absolutely prove that structure can fast and effectively exclude boss surface water quality very much, effectively reduce the risk of brake fade
2nd, calculated according to rigid stress value, show that the increase of design thickness value can be with the rigidity of very effective lift structure
Intensity, in present invention brake side structure, brake side adopts boss design structure, equal material, etc. can be with quality requirements
Design thicker size to meet the lifting in intensity.
3rd, under condition of equivalent, area of dissipation is bigger, and radiating effect is better, and boss structure increased four side face areas,
Actually used process we demonstrate effect, good heat dissipation effect can reduce product and brake the temperature on side, it is ensured that product material
Can will not fail or reduce because temperature is too high, it is ensured that product brake side will not deform because of temperature, rim be lifted using safety
Property.
4th, in actual test checking, because of the lifting of coefficient of friction, the brake rubber block loss protection to braking also rises certain
Effect, can extend the service life 25% of brake rubber block.
5th, in actual test checking, when rim is braked, 10-20 degree can drop in mean temperature.
6th, under condition of equivalent, braking effect can be reached with less Brake handle power.
