Abstract

An automobile tyre anti-skid ring provides a tyre anti-skid device for the automobile running on a snow and ice roadway. The anti-skid ring is formed by the rubber mother metal moulding of a skeleton ring, an interval layer, a tyre tread, a cushioning layer, a cord fabric layer, cluster fiber, inner layer and a localization bulge. The integration of the automobile tyre anti-skid ring is in a circular ring shape and the cross section of the automobile tyre anti-skid ring is in a sectorial shape. The automobile tyre anti-skid ring utilizes the cluster fiber and a tyre tread circular pit to enhance the gripping force between the tyre and the ground. The utility model has the advantages of good anti-skid effect, little possibility to damage the ground, convenient installation and operation, low cost and simple structure.

Description

Automotive tyre anti-skid ring

The utility model belongs to a kind of antiskid device for tyre of installing and using on motor tire.

The frequent accumulated snow in road surface in winter of north severe cold freezes; motor tire and ground-surface friction force have been lowered; drag is ineffective; bring many difficulties for the cruising of automobile; having a strong impact on people's production and life; even pernicious traffic accident repeatedly takes place every year; cause the consequence of car crash; the waste of fuel is also very surprising simultaneously; statistical information according to the energy-conservation center of Harbin City planning commission shows, exceeds more than 30% at the oil consumption ratio of traveling automobile on the ice and snow road with traveling automobile on pitch, sand-gravel surface.Be to solve the anti-skidding problem that motor tire travels on ice and snow road, the colored tire of each class formation occurred, as winter special tyre, edge follow closely tire etc.; Binding metal anti-slipping chain on the general-utility car tire also occurred, the method that devices such as plastics anti-slipping chain perhaps are installed is for the skid resistance that improves motor tire and ice and snow road has played certain effect.But, install and use inconvenience, so up to the present use very not extensive because skidproof effect is not obvious.

The purpose of this utility model is exactly on the basis that does not influence the motor tire rideability, start with from the grabbing coefficient and increase tire and ground-surface area of contact aspect that improve tire and ice and snow road, design that a kind of antiskid capability is good, easy to install, simple in structure, the motor tire antislip ring of wide accommodation, when being travelled, it guarantees that automotive safety is reliable on ice and snow road, with the purpose that reaches the desirable skidproof effect of automobile and save fuel oil consumption.

Basic design of the present utility model is, it is annotated by the rubber nut material mould by skeleton ring, wall, tyre surface, cushion layer, carcass plies, nexine, bunch silk and eight parts of positioning convex and forms, its tyre surface forms circular arc, and the plurality of rows pit arranged, several bunch silk roots that close up cluster are pricked solid on skeleton ring, and bunch rostellum of its bunch silk goes out the tyre surface certain size.

The utility model has made full use of the cluster bunch silk of outstanding tyre surface and the pit of tyre surface itself, and the elasticity of rubber nut material, improved the holding power of motor tire and ice and snow road greatly and increased ground contact area, have antiskid capability good, easy to install, with low cost, do not damage the ground-surface characteristics.

Fig. 1 is the inner structure scheme drawing of motor tire antislip ring cross-sectional plane;

Fig. 2 is that motor tire antislip ring overall shape reaches scheme of installation between motor tire.

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The motor tire antislip ring is annotated by the rubber nut material mould, integral body is toroidal, its cross-sectional plane is like fan-shaped, be made up of skeleton ring 1, wall 2, tyre surface 3, cushion layer 4, carcass plies 5, bunch silk 6, nexine 7, positioning convex 8: three chop bobbins, 1 employing structure steel rope rolls and is the circle shape, wherein the circle diameter dimension of the skeleton ring 1 in the outside, both sides is identical, and the circle diameter dimension of middle skeleton ring 1 is slightly larger than the circle diameter dimension of the outside, both sides skeleton ring 1; Cover is knotted bunch silk 6 that several close up cluster equably on the circumference of every skeleton ring 1,15～20 bunches of per 30 centimetres of nooses, each bunch silk 6 is made of 20 left and right sides spring wires, and bunch silk 6 roots are tightened location on skeleton ring 1 with the silk rope, and bunch rostellum of each bunch silk 6 is for 2～3 millimeters on tyre surface 3 surfaces; Carcass plies 5 is looped around three skeleton ring 1 outsides, forms cushion layer 4 in a side of the close tyre surface 3 of carcass plies 5 with the rare cord that hangs with 2～3 layers of glue-line, separates maintenance with wall 2 between inboard and 7, three skeleton rings 1 of left and right side configuration nexine; Form shape with the rubber nut material mould, make outermost tyre surface 3 be circular arc, arcuate surface is provided with two row's circular pit, outpours a fixed number positioning convex 8 on inclined-plane, the both sides circumference, so far constitutes the motor tire antislip ring.

During installation, the car body pad is risen, make the wheel that the motor tire antislip ring will be installed unsettled, unclamp the nut that tightens up wheel rim 10, unload outboard wheels 9 after, the suit tire anti-slip circle of getting on the car, outboard wheels 9 is loaded onto, the position of motor tire antislip ring between two tires adjusted on fastening nut limit, limit again, is strictly on guard against eccentric unbalance, positioning convex 8 on the inclined-plane, both sides is embedded in the groove of outboard wheels 9 and 11 liang of tire protector sideway stances of inboard wheel, tighten the use of to travel after nut, the locking.Such structure has guaranteed that tire does not produce relative slippage with the motor tire antislip ring closing the position under steam, simultaneously, also rely on motor tire antislip ring tyre bead cross-sectional width greater than and adorn the size of space between two tires, when tightening rim nut, produce to give and answer tightness, be that interference and closed, the auxiliary again circular shape with tyre surface 3 produces again to both sides tension force when the contact ice and snow road, makes it in conjunction with more tight.

This utility model can go out corresponding specifications and models series of products according to the specifications and models accessory processing of tire, satisfies customer requirement.
