Abstract

The utility model relates to a new type bike shock absorption tire which mainly consists of a bike tire, elastic balls and a bike steel rim. The model is characterized in that: the elastic balls are between the bike tire and the bike steel rim. Diameter of the elastic mall matches internal diameter of bike tire and diameter of the steel rim, so that the elastic balls can take up all the space between the bike tire and the bike steel rim. The utility model is of strong adaptability, good shock absorption performance, inflation free, anti-puncture, easy to install, good wheel elasticity, tensile strength, tearing strength and anti-aging performance. Tires will not burst or leak even under drastic external condition (such as temperature) changes, and have such advantages as reliable safety, long service life, low technical requirement and easy production.

Description

A kind of new bicycle damping tire

Technical field

The utility model relates to a kind of bicycle shock absorption device.

Background technology

Bicycle damping at present mainly relies on air bag damping, rubber shock-absorbing etc.The air bag damping: the inner tube of a tyre of bicycle generally is made up of air bag, and air bag can effectively be faced the impulsive force of vehicle body with absorbing.Because it and ground direct contact, thereby the damping effect that is risen is fairly obvious, and when particularly riding on rough road surface, air bag can obviously reduce the vertical tremor of vehicle body.Air bag is to utilize the volume change of leak free gas to realize shock-absorbing, and its advantage is light weight and is not afraid of agingly that shortcoming is exactly easily gas leakage, must charge into an amount of and enough air in good time.And rubber shock-absorbing because rubber has better elastic and resistance to abrasion, is wrapped in the outside face of air bag outside as wheel with it, can be so that the damping effect of wheel is better.Also has a kind of non-inflatable tyre (Chinese patent 200420112008.9), adopt special foam material, have that good springiness, resistance to abrasion are strong, safer, the characteristics (being common airtyred two to three times) of longer service life, thereby its actual operating costs is also lower than air-inflation tyre, the more important thing is that it can allow the user save a large amount of quality time and safe guarantee is provided.Generally speaking, there is following problem in prior art:

(1) pressurized air in the existing bike tire is subjected to the influence of external condition bigger, when temperature is too high or external pressure when excessive, makes inner tube of a tyre explosion easily;

(2) inner tube of a tyre is punctured by sharp object easily, and after breaking, tire then no longer plays damping effect, makes troubles to the bicyclist;

(3) need configuration Floor Pump, annexes such as valve inside.

The utility model content

The purpose of this utility model is to provide a kind of new bicycle damping tire, and this tire applicability is strong, and damping performance is good, situations such as under the bigger situation of temperature traverse, blowing out can not appear in tire, inefficacy.

A kind of new bicycle damping tire, mainly form by cycle casing, elastic pellet, bicycle rim, it is characterized in that, described elastic pellet is between cycle casing and bicycle rim, the diameter of described elastic pellet matches with cycle casing internal diameter and rim diameter, makes elastic pellet can fill space between cycle casing and the bicycle rim.

The utility model is because to be cars on hand fetus in fetus position replace with the caoutchouc elasticity bead in the inside of tire outside, when wheel contacts with ground, have at least the hemispherical portion of a bead to contact with ground, and other several beads also have and ground contacting in various degree, this way of contact had both guaranteed the continuity (being similar to Principles of Gear Connection) of wheel distortion, when having reduced single bead again and having contacted with ground, the pressure that is subjected on the contact surface, thereby increased service life.Because rubber has very big internal friction, therefore in distortion and recuperation, a part of mechanical energy that absorbs can be converted into heat energy, thereby produce damping effect.In recuperation, can produce damping effect behind bead in the wheel and the ground contact deformation, play the effect of bumper and absorbing shock.

The diameter of described elastic pellet should match with cycle casing interior diameter and rim overall diameter, therefore when the design flexibility bead, must select suitable little ball diameter, make elastic pellet can surround whole rim, the diameter d of elastic pellet and rim diameter D should satisfy following relation:

$\mathrm{\π}/\arcsin \left(\frac{d}{D+d}\right)=Z$ (Z is an integer)

Parameter declaration: bicycle rim diameter D

The bead diameter d

Bead quantity Z

$\mathrm{\π}/\arcsin \left(\frac{d}{D+d}\right)=Z$ (Z is an integer)

The internal diameter of cycle casing also should match with little ball diameter.Because the dimensions of the cover tire of bicycle is more, therefore can after designing the bead that matches with rim, select the cover tire of suitable dimension again.

For each elastic pellet is remained in the relatively-stationary position range, and be unlikely to take place big slide relative on rim, when making bead, open an aperture and be convenient to fixedly elastic pellet at the ball size place.

The utility model is determined the bead number according to the rim overall diameter earlier in when assembling, with rope it is gone here and there together and is enclosed within on the rim, puts cycle casing at last and gets final product.

Select the elasticity height for use, intensity is big, and resistance to abrasion is good, and the variable hardness scope is big, and price is not high, and easily material processed is made bead.As polyurethane (PU), its chemical constitution is poly-amino methyl, and density is 1.1-1.25g/cm ³, tensile strength is 70Mpa, and resistance to abrasion is good, and elasticity is also very big.

Compared with prior art, the utility model applicability is strong, and damping performance is good, situations such as under the bigger situation of temperature traverse, blowing out can not appear in tire, inefficacy.Its main advantage is as follows:

(1) exempts to inflate, is not afraid of bundle, long service life, easily installs, even completely iron nail also can cruising, solved fully that common air tyre does not tightly lose heart because of the tire tube valve sebific duct is bonding, valve inside gas leakage, sharp object thorn are leaked gas, the not enough flat gas of tolerance and the excessive drawback of blowing out of air pressure;

The process of (2) saved tire patching, changing tire does not need to dispose Floor Pump;

(3) have that quality is good, resistance to abrasion is strong, good springiness, safety are good, the characteristics of long service life;

(4) wheel rebound resilience, extensibility, peel strength and ageing-resistant performance are good;

(5) compare with band tyre and have in light weightly, technical requirements is low, produces advantages such as realization easily.
