Abstract

The utility model relates to an inflatable inner tube product for a manpower vehicle and a motor vehicle. The utility model makes an inflation body into a hollow ball whose elastic object is filled with air. An entire tyre body is a circular ring structure which is composed of elastic locating pieces. The elastic locating pieces comprise a plurality of hollow balls. The utility model is made into a full control of access and high elastic type inner tube of tyre for a vehicle. The utility model does not need to inflate and can not leak air. The utility model can keep a due pressure. The utility model has the advantages of time saving, labor saving and high durability. The utility model cares nothing for piercing. The integral pressure change can not be influenced even a plurality of center penetration ball small air chambers are pierced. The utility model can run back again after piercing objects are taken out. An abrupt accident does not exist. The utility model does not need to repair or replace. One inner tube of tyre for a vehicle can be used for ten years. The utility model is not influenced by environmental factors such as air temperature, etc. The utility model has the advantages of good adaptability, smooth and buoyant run and good buffering capability.

Description

Inner tube of vehicle tyre

The utility model relates to a kind of inflatable inner tube product of rickshaw, automobile tyre.

Present tire for vehicles as the tire of automobile, motor bike, bicycle etc., has inflatable, without inner tube type, solid formula etc., and is varied.But be to use the most general, most popular still inflatable tire, this is because its buffer capacity is strong, has better elastic, can bear very big pressure, the brisk cause of travelling.Common inflatable tire is all constituted by cover tire and inner tube of a tyre two large divisions, and its inner tube of a tyre adopts the annulus sebific duct as the inflation body, and copper tire tube valve and fastener etc. are housed on the sebific duct carcass, is whole annulus sebific duct inflation at any time by tire tube valve, forms pressure.The weak point of the existing inflatable inner tube of a tyre mainly is: 1, need often inflate, keep due pressure, and comparatively time-consuming bothersome, also corresponding utensil to be arranged; 2, travel, in case occur being pricked or explosion or grind burst accidents such as damage, can't ride, the end user is caught unprepared, and must repair or change, cause delay easily; 3, use Effect of Environmental such as being subjected to temperature, midsummer and severe cold all can make the decline of inner tube of a tyre life-span, damage rate improve.

The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of puncture that need not to inflate, be not afraid of, the Puffer-type inner tube of vehicle tyre product that not influenced by temperature.

Can take following technical scheme to realize purpose.To inflate system and become gas filed hollow ball in the elastic, whole carcass contains some hollow balls with flexible positioning piece and constitutes circular ring structure.Make totally-enclosed, super elastic inner tube of vehicle tyre product.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is a kind of structural entity generalized section of the bicycle use inner tube of a tyre;

Fig. 2 is a kind of structural entity generalized section of automobile with the inner tube of a tyre;

Fig. 3 is the schematic cross-section of Fig. 1 inner tube of vehicle tyre.

The inflation body of this inner tube of vehicle tyre is gas filed hollow ball (a 1) structure in the elastic, and promptly it is the totally-enclosed elastic component with certain pressure.It can adopt various elasticity rubber and so on material manufacture preferably, and the size of the sphere diameter of hollow ball, wall thickness and filled pressure all can be selected according to using needs to take the circumstances into consideration.If adopt stretch surely value be in the natural rubber of (Huang) make base-material, suitably add the raw material of oxidation inhibitors such as butyl rubber and silicon dioxide, DOD, H, anti-ageing agent, white carbon formation; Press the rubber routine, with blow moulding machine, the made hollow ball of injecting compressed air on stream, best results.Locations (2) also should adopt various elasticity material manufacture preferably, wherein latex is comparatively desirable, as in natural emulsion, suitably adding styrene-butadiene latex, anti-ageing agent DPPD, MS, vulcanization accelerator, TMTM, vulcanizing activator, the raw material that soften flux and silicon dioxide etc. constitute pours into the circular ring structure that contains some hollow balls, coagulation forming formation with it in mould, effect is preferable; Both can make hollow ball be able to strong fix, guarantee that the inflation spheroid was evenly distributed, and have again and scratch tropism and elastic force preferably, be beneficial to installation, and make the cover tire turgor, enrich, guarantee the cushion characteristic of whole tire.

In the accompanying drawing institute example, the hollow ball of inner tube of vehicle tyre (1) is to adopt rubber to make sphere diameter Φ 10-Φ 30MM, wall thickness 1-5MM, in fill 1-3 atmospheric structures.They can adapt to all kinds of power cars, power actuated vehicle, and the use of different types of tyres needs.

The carcass of inner tube of vehicle tyre is to adopt latex locations (2) to contain the circular ring structure of some hollow balls (1) moulding, and two sides of annulus are provided with straight burr or reticulate pattern structure (3), and inside and outside anchor ring place is provided with double wedge or paliform structure (4).Striated structure is beneficial to the inner tube of a tyre and locatees in cover tire, increases friction force between the two.Double wedge or paliform structure can strengthen elasticity, and cover tire is produced the effect of squeeze expanding better, can prop up cover tire better, delay service life of cover tire.

Adopt existing instrument or existing instrument made improvements slightly and can carry out inside and outside tire and install toward wheel rim on, this is to have better elastic and plasticity owing to this inner tube of a tyre.

The relative prior art of the technical program has following advantage:

1, need not inflate, can not leak gas yet, always keep due pressure, save time Save trouble, need not valve cock and corresponding utensil etc.

2, durable in use, be not afraid of puncture, in the 28 type bicycle tubes Φ 10M is just arranged About 20,000 of the hollow ball of M can not affect integral body even if pierce through the little air chamber of several hollow balls yet Air pressure change, travel after taking out the puncture thing in the same old way, do not have burst accident, no matter is advanced Row is repaired or is changed, and inner tube of a tyre can be with 10 years.

3, use Effect of Environmental such as not being subjected to temperature, midsummer and severe cold are little to the influence of little air chamber, and comformability is good.

4, travel steadily, brisk, cushion characteristic is good.
