The material of vacuum type tire is mainly rubber and some reinforcing materials, when tire is pierced through by taper shape foreign objects such as nails, though the vacuum type tire has certain anti-stab performance, but causing the flat tire phenomenon of blowing out or leak gas slowly happens occasionally, all air-inflation tyres risk of all blowing out influences traffic safety, needs inflation and tire patching simultaneously, thereby the increase maintenance cost delays running time.
A kind of moonfall spring tyre being arranged in addition, be made by the closely vertical flat raft row of 800 load bearing spring materials, is not that rubber is made, and principle and technology are all very complicated, and cost is too high, and it is limited particularly to travel, and is not suitable for normal domestic.
Summary of the invention
At the defective that above-mentioned prior art exists, the utility model is intended to release a kind of safety anti-explosive spring tyre, can prevent that tire is by the foreign object puncture, solving air-inflation tyre blows out under the prerequisite of problem, can also pass through appropriate design, further reduce productive costs, easy to use and popularization.
For this reason, the utility model adopts following technical scheme: a kind of safety anti-explosive spring tyre, comprise wheel rim and carcass in the form of a ring, and the utility model is characterised in that, is provided with spiral and is wound in the compression shape spring that coincide with the wheel rim shape between carcass and wheel rim; The compression shape spring of close outermost carcass is planar with the carcass contact surface for one section and contacts.
As embodiment, the cross sectional shape of the stem bar of described compression shape spring is various polygons such as triangle, quadrangle, pentagon.
Further, also be provided with the wheel rim bed course between described wheel rim and the compression shape spring, described wheel rim is provided with the groove that is used for clamping compression shape spring.
The cross sectional shape of the stem bar of compression shape spring described in the utility model is improved by circle of the prior art, this compression shape spring is planar with carcass for one section at close outermost carcass at least and contacts, can be chosen as polygon or large semi-circular etc. according to production technology and mould, when making the circumference outermost of compression shape spring of spiral surrounding contact with the outermost carcass, become the face contact, rather than line contact of the prior art, thereby when compression shape spring is passive, reduced the pressure of compression shape spring to carcass and wheel rim.
In addition, wheel rim described in the utility model is provided with the groove of placing compression shape spring, generally is recessed into 1/5th to 1/2nd of cumulative volume, makes spring tight with contacting of wheel rim, and tire running is stable.Because the utility model mainly relies on compression shape spring to play a supportive role, the colloid volume of the carcass in the compression shape spring outside can reduce greatly than the used carcass of tire before, accounts for 1/4th to 1/2nd of compression shape spring.As specific embodiment, can be only the tire ground contacting portion with contact wheel rim colloid partly arranged because tire described in the utility model mainly supports by spring, therefore, the technology of the colloid of carcass part can be simplified.Saved elastomeric material like this, also alleviated tire weight, particularly simplified the complicated technology that present tire production needs, optimized from producing many-sides such as time of needing, raw MAT'L, technology.
In sum, the improvement of safety anti-explosive spring tyre described in the utility model by existing spring tyre is carried out, make spring tyre more durable and reliable, and make simple, with low cost, easy to use, be easy to promote, have extensive use and market, especially at military affairs, complex road surface, civilian instrument etc., and crucial vehicle aspect.

The specific embodiment
Shown in Fig. 1-2, present embodiment provides a kind of safety anti-explosive spring tyre, comprises wheel rim 4 and carcass in the form of a ring 1, is provided with spiral and is wound in the compression shape spring 2 that coincide with the wheel rim shape between carcass 1 and wheel rim 4; Also be provided with wheel rim bed course 5 between described wheel rim 4 and the compression shape spring 2, described wheel rim is provided with the groove 6 that is used for clamping compression shape spring.Make and compress shape spring 2 and wheel rim 4 firm combining, increased the strong degree of tire.
The compression shape spring of close outermost carcass 3 is planar with the contact surface 8 of carcass for 2 one sections and contacts.As specific embodiment, the cross sectional shape of the stem bar 7 of described compression shape spring can be for being the large semicircle shape of straight line by outermost carcass one side, as shown in Figure 3.Also can be hexagonal shape, as shown in Figure 4, can change the stem bar into the face contact to the contact surface of outside carcass by the line contact like this, significantly reduce the pressure of spring, thereby make spring diminish the pressure that the carcass and the inboard wheel rim bed course in the outside produces to carcass.Described cross sectional shape can be other shapes, is the face contact to carcass as long as this cross sectional shape guarantees spring for one section by the outermost carcass.
What the compression shape spring 2 that the described safety anti-explosive spring tyre of present embodiment needs adopted is high structure stability compression shape spring, is that main material is made by spring steel generally, is divided into steel wire and steel band according to tire load-carrying needs.Its high structure stability is meant because the good comprehensive elasticity under quenching and Annealed Strip, its elasticity depends on the performance of steel and the ability of elastic deformation, promptly within the scope of regulation, the ability of elastic deformation makes it bear certain load, permanent deformation do not occur after load is removed, performance requriements is high strength and high yield limit and fatigue limit.High structure stability compression shape spring has excellent comprehensive performances, as mechanical property (particularly elastic limit, strength limit, yield tensile ratio), elasticity attenuation resistance can (be the elastoresistance performance that goes down, claim anti-relaxation property again), fatigue property, quenching degree, physical and chemical performance (heat-resisting, low temperature resistant, anti-oxidant, withstanding corrosion etc.), be not acted upon by temperature changes in order to satisfy its precision, generally select for use modulus of elasticity and coefficient of expansion to change minimum constant modulus alloy.Plastics spring is the plastics spring that matrix is made by epoxy resin, phenol resin for example because properties, particularly reinforced plastics such as its light weight, insulation, anti-collision, rust protection also are suitable for according to different types of tyre load-carrying situation in addition; The thermosetting reinforced plastics GFRP that strengthens with glass fibre, also comprise simultaneously and select for use vibration-proof rubber to make various types of rubber springs etc.
Because above-mentioned compression shape spring has played good supporting role, and the requirement of strength that meets tire, therefore can reduce by the exterior carcass portion of compression shape spring, as long as the colloid that guarantees to have in the position of tire kiss the earth carcass is partly, like this can be so that cost reduces greatly.
