Abstract
The invention discloses a bicycle rim with a concave-convex-structure outer ring protection layer, which belongs to the technical field of bicycle production. The bicycle rim is characterized in that the outer surface layer of the side wall of the rim is a concave-convex-structure outer surface layer which is arranged in a region corresponding to a supporting beam for separating a tire trough and a bearing ring. The bicycle rim has the beneficial effect that the outer surface layer of the rim side wall is the concave-convex-structure outer surface layer, so that friction force generated when the rim is clamped by a brake block increases to improve a brake effect, and a bicycle is unlikely to slip on rainy day or on a clay court or a wading pavement; meanwhile, gaps are formed between the brake block and the rim outer surface layer due to a concave-convex structure to release heat generated by friction, and thus the brake effect can be prevented from alleviating; the rim can be protected after the bicycle is used for a long time since the outer surface layer is firstly abraded; the concave-convex-structure outer surface layer is distributed in the supporting beam region, clamping force generated by braking is accepted by a supporting beam, the rim is prevented from being damaged, and thus the service life of the bicycle is prolonged; and the stable braking effect can be used for enhancing the physical security of a rider.
Description
Technical field
The present invention relates to a kind of bicycle rim, belong to the bicycle production technical field, the particularly a kind of bicycle rim that can strengthen the band concaveconvex structure outer ring protective cover of braking effect and protection wheel rim.
Background technology
Bicycle develops into so far, allows China be worthy of the appellation of " bikedom ": about 1,000,000,000 of the present bicycle recoverable amount in the whole world, and China occupies 4.7 hundred million; Continuous 6 annual export volumes of made in China bicycle surpass 1,000 ten thousand, account for 45% of world's car load trade.Along with the development of society, prosperity of economy, the variety of the vehicle allows bicycle also once lose its splendidness in the past; Along with being rooted in the hearts of the people of environmental protection low-carbon (LC) notion, increasing people picked up this memory fragment that how long it is since we last met again but in the last few years,, ride bicycle and be to and from streets and lanes, and exhaust possibly it dress up pure and fresh romance, unique individual character becomes in the city scenery of beautiful uniqueness together.At home, producer was making great efforts to create the bicycle new ideas that grow with each passing hour more voluntarily: strengthen the multifunctionality and the safety of bicycle, make a kind of pursuing freedom spirit and the life style of breaking away from heavy traffic pressure.Meanwhile, the market of bicycle also is enriched thereupon.
Bicycle is a manpower foot-driven two-wheel car, claims bicycle, bicycle again.Noiseless, pollution-free, from heavy and light, simple in structure, cost is low, use is easy to maintenance, is widely used in that traffic is ridden instead of walk, carried cargo, physical training and contest etc.Development along with society, the raising of people's quality of life, also pay attention to self healthy health care is added the popularization of cycle racing, allow people know by bike benefit: its benefit is in unlimited time, speed limit degree not, not only can lose weight, but also can make symmetrical because cycle racing is the motion that needs a large amount of oxygen, so can also strengthen cardiac function, simultaneously can also prevent hypertension, more effective than medicine sometimes.Step on bicycle compression blood vessel, make blood circulation quicken, brain is taken in more oxygen, adds to suck a large amount of fresh airs, can think that brains are clearer.Ride onboard, you can feel very free and be happy incomparable that it no longer is a kind of walking-replacing tool, especially the mode of joyful soul.Because light, the environmental protection of bicycle, can also play the effect of body-building when advancing riding instead of walk, so its development space is boundless.
In the various function systems of bicycle, brake function is a key link, is related to user's traffic safety and health safety.Bicycle brake system mainly contains to clamp and stops and disc brake at present, and two kinds of brake system are each has something to recommend him, and pincers are stopped and can slowly be braked, and impulsive force is little, relatively safety; The braking effect of disc brake is good, but the anxious danger of overturning of having stopped.
The most employings of bicycle at present clamp the systems of stopping, and it is a kind of very common braking device that pincers are stopped, and clamp wheel rim by two brake facings and produce friction force, thereby reach the effect of braking, its advantage is in light weight, and is simple in structure, be convenient to installation, C﹠M, cheap, the cost performance height; Shortcoming is easily to skid in rainy day, mud ground or the road surface of paddling, and long-time friction can be given birth to heat, reduces braking effect, and the long-term use meeting is worn wheel rim.
Summary of the invention
Technical matters to be solved by this invention is: at the deficiencies in the prior art; provide a kind of brake system that can prevent to skid; give birth to heat; and can protect the constructional device of wheel rim; with braking quality that improves bicycle and the service life that prolongs bicycle, strengthen bicyclist's traffic safety and health safety.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is a kind of bicycle rim with concaveconvex structure outer ring protective cover, comprises wheel rim, it is characterized in that wheel rim sidewall uppermost layer is the concaveconvex structure uppermost layer.
Described concaveconvex structure uppermost layer land are in the supporting traverse The corresponding area of cutting off tire groove and load-bearing circle.
Described concaveconvex structure is a kind of in shrinkage pool structure, bump structure, groove structure, the cord tissue, or the wherein combination of two or more structures.
The depression radius of described shrinkage pool structure is 0.15-0.95mm.
The protruding radius of described bump structure is 0.15-0.95mm.
The depression radius of described groove structure is 0.15-0.95mm, can be rectilinear form, turnover shape or curved shape.
The protruding radius of described cord tissue is 0.15-0.95mm, can be rectilinear form, turnover shape or curved shape.
Directly clamp brake facing during use, brake facing is clipped on the concaveconvex structure uppermost layer, can increase braking effect energetically and protect wheel rim.
The invention has the beneficial effects as follows that wheel rim sidewall uppermost layer is the concaveconvex structure uppermost layer, the friction force in the time of can increasing brake facing clamping wheel rim, thus improve braking effect, even also be difficult for skidding at rainy day, mud ground or the road surface of paddling; Concaveconvex structure can make between brake facing and the wheel rim uppermost layer and produce the gap simultaneously, is convenient to discharge the heat that friction produces, and can prevent to reduce braking effect; In addition, because uppermost layer is arranged, after the long-term use, what at first be worn is uppermost layer, can protect wheel rim; The concaveconvex structure uppermost layer is distributed in the supporting traverse zone, and the gripping power in the time of can making brake is accepted by supporting traverse, avoids destroying wheel rim, improves the service life of bicycle; Stable braking effect can also strengthen bicyclist's Personal Safety.
