Abstract

The utility model relates to a tire for vehicles. The tire for vehicles is characterized in that inner and outer tires are combined into one; the tire for vehicles has the advantages of no inflation, scratch and puncture prevention, convenient assemblage without maintenance, and long service life. The utility model can be widely suitable for various vehicles in the world.

Description

Do not inflate the hollow tire

The utility model relates to a kind of traffic and transport field vehicle tyre.Particularly a kind of tire that is applicable to that various automobile, motor bike, bicycle, trac., battery charger truck, rickshaw use.

Tire is all kinds of vehicle chief components.It is to be the Tire ﹠ Tube that material is made with rubber.The inner tube of a tyre mainly relies on inflation to produce application force and supports cover tire and act on ground and produce counter-force and come supporting body.The inner tube of a tyre is not inflated or underinflationly just can not be worked." common fault " of all tire is exactly gas leakage easily, and this is a big defective of rubber inner tube.People just think: tire has become flat suddenly on the way to office, and how worried this can make us! Tire in the enforcement becomes flat suddenly or quick-fried gas, can block the traffic, and when serious major traffic accidents can take place, and causes the tragedy of car crash!

How much whole world has cause great loss nobody to add up because of tire becomes flat.But in China's 1,200,000,000 populations, it is the vehicle with the bicycle that people more than 300,000,000 is arranged according to statistics, also have the total amounts of adding up such as various automobile, motor bike, rickshaw, battery charger truck, trac. just to have five, 600,000,000 more than in addition, like this vehicle of enormous quantity, annual the life and property loss that accident that factors cause brings for country, individual family such as to pierce through be beyond measure because of tire scratches.Therefore social call a kind of possible alternative can occur and solves this type of technical matters.

The purpose of this utility model is exactly to be badly in need of and a kind of Tire ﹠ Tube of design-calculated unites two into one at above-mentioned defective and society, it has does not inflate, be not afraid of and scratch and pierce through, easy to assembly, safe and reliable, need not keep in repair, long service life, manufacturing process simply is the novel tire of feature, it is applicable to all types of vehicle tyres, this tire is not because of inflating, reduce a lot of links, also reduced simultaneously all kinds of traffic accidents and the personal casualty that causes because of tire flat, save a large amount of maintenance funds and valuable time to people, bring great convenience also for people's live and work, therefore social benefit still be economic benefit all be huge, if promote its meaning in the whole world more great.

The utility model is achieved in that with bicycle technology be example.All have retractility and this characteristic of elasticity according to rubber and metal (light metal is better) spring, through being processed into a kind of mixing tire.Its principle is that a spring is set, spring is fixed into circle head and the tail weld together, and one screw rod is set, have arc-shaped pad and nut on the screw rod at the solder joint place, be provided with in the spring periphery simultaneously and twine the adhesive bandage multilayer, place mold cavity warp and rubber batching moulding by casting.Other component part rim of tire, spoke, axletree hold physical dimension and all remain unchanged, so that match with novel tire.

Accompanying drawing 1 is this tire front elevation (section-drawing).

Accompanying drawing 2 is a support front elevation in the closed hollow spring of this tire.

Fig. 1, this tire shown in Figure 2 comprise: rubbery cover tyre 1, spring 2, rim 3, bearing 4, Spoke 5.

Be tied with multilayer rubberized tape 6 on the spring 2, the purpose of twining rubberized tape is to intercept rubber liquid watering Non-leakage in the hollow spring inner chamber in the notes process, rubberized tape has adhesive force simultaneously, exists easily During cast and rubber liquid bonding. The place establishes solder joint 7 at the hollow spring initial and end, guarantees that spring makes With in not loose. 7 places are welded with screw rod 8 at solder joint, and the purpose that screw rod 8 is set replaces original rubber Valve inside air valve screw rod on the inner tube of a tyre makes the tire overall structure constant, and is easily supporting. At screw rod Have arc-shaped pad 9 and nut 10 on 8, combine closely to strengthen novel tire and rim.

Embodiment:

Choose the steel wire of thick, thin hardness, suitable elasticity earlier, turn to spring through processing, and be fixed into great circle, spring is welded from beginning to end weld, and, have arc-shaped pad and nut on the screw rod at weldering one of solder joint place and the same screw rod of former valve inside air valve screw size.Spacing distance between the every ringlet of spring answers equal distribution even, meanwhile twining totally enclosed of multilayer adhesive bandage formation on ready-made spring is the spring tyre of support with the hollow spring, spring tyre is placed mold cavity, choose the processing pouring temperature, rubber raw materials poured in the mold cavity pour into a mould, behind the shaping and demoulding outward appearance is rebuild, promptly finish a novel tire.The outward appearance of novel tire keeps the whole original appearance features of former tire profile decorative pattern.

(according to said method, according to different vehicle tire physical dimensions, select the steel wire of different cross section, hardness, suitable elasticity, can legal system circular, special-shaped hollow spring tyre uses for different car types).

Assembling: will pour into a mould in the valve inside hole on the screw rod insertion rim on the good tire, and tire will be assembled on the rim, and will to screw rod, tighten and to use on arc-shaped pad and the nut with instrument.

This technology is through manufacturing experimently on probation producing a desired effect.

Claims

1, a kind of hollow tire of not inflating, it comprises: rubbery cover tyre (1); Spring (2); Rim (3); Axletree holds (4); Spoke (5).It is characterized in that twining on the hollow spring adhesive bandage (6), forming a totally enclosed is the spring tyre of inner support with the hollow spring, becomes Tire ﹠ Tube and unite two into one and do not inflate tire behind castable rubber.

2, by the described above-mentioned hollow tire of not inflating of claim 1, it is characterized in that the cast of rubbery cover tyre (1) and spring (2) is synthetic, spring (2) head and the tail joint is provided with solder joint (7), and screw rod (8) links to each other with solder joint (7), and arc-shaped pad (9) and nut (10) are housed on the screw rod (8).
