Description

A kind of damping trailer tire

Technical field

The utility model relates to band tyre technical field, specifically a kind of damping trailer tire.

Background technology

In engineering machinery vehicle, widely used band tyre generally comprises polyurethane solid tyre and poly-urethane rubber compound solid tire.Band tyre has unique advantage, such as: puncture resistance, resistance toly to tear, without the need to inflation and the feature using long service life.But also have its shortcoming, main manifestations is: its cushion characteristic is poor, elasticity is not enough, the goods of fragile vehicle and loading, and fragile road surface and kinetic equation loss large.

The wheel hub that common polyurethane realizes using in tire is all full rigidity, does not substantially have elasticity, so the elasticity of existing band tyre is relatively poor.

Utility model content

The purpose of this utility model is to provide a kind of damping trailer tire, first be a kind of band tyre, and make it that there is the damping performance not available for solid plain tire by structure of modification, especially possess excellent damping performance, meanwhile, the bulk life time of tire is improved further.

The technical scheme in the invention for solving the technical problem is:

A kind of damping trailer tire, comprise the wheel hub of rigidity and flexible tyre surface, it is characterized in that, described wheel hub is made up of inside and outside steel ring and the Flexible Connector be clamped between inside and outside steel ring, the outside face of described interior steel ring is provided with some draw-in grooves circumferentially carrying out being evenly arranged, described outer rim diameter is comparatively large, and the inside face of outer rim is provided with some draw-in grooves;

Described Flexible Connector is Z-shaped punching press steel part, described Flexible Connector two ends are that interface is plugged in the draw-in groove of inside and outside steel ring respectively, and rely on the elasticity dynamics of self to prop up, and use welding process both to be linked into an integrated entity at connecting portion, form an elasticity and connect; Under the effect with external impacts, an elastomeric distortion between inside and outside steel ring, can be formed, increase overall elasticity.

Be provided with the groove of some annulars at the outside face of outer rim, described groove is along the distribution of outside face circumference, and surface coverage one deck rubber layer or layer of polyurethane form tyre surface outside.

Further, there is in the Z-shaped turning point of described Flexible Connector prolongation afterbody outwardly.

Further, all draw-in grooves are all cone tank.

Further, in the outside face process of outer rim, form hamulus one by one, be engaged with the tyre surface of tire, improve anchoring strength.

Further, the ring surface of tyre surface is provided with grab ground decorative pattern.

Further, be provided with anti-side in the two sides of described tyre surface and draw projection.

The beneficial effects of the utility model are: the utility model by by traditional hub design be interior, in, outer three layers, take full advantage of superhard, the elastomeric performance of middle spring attaching parts, improve overall elastic performance.Farthest can ensure the elastic performance of tire entirety, and actv. damping effect can be formed in the use procedure of reality.There is the damping performance that general band tyre does not have, improve traveling comfort and the stability of vehicle carrying.The field such as tractor-trailer on various industrial vehicle, military vehicle, vehicle for construction, airport, harbour can be widely used in.

And the junction of tyre surface and wheel hub is provided with hamulus, formed at both faying face places and strengthen structure, strengthen anchoring strength between the two.

Fig. 3 is the section-drawing at A-A place in Fig. 2.

Fig. 4 is the layout schematic diagram of hamulus on outer rim.

In figure: steel ring in 1,2 outer rims, 21 grooves, 22 hamulus, 3 Flexible Connectors, 4 rubber layers, 41 grab ground decorative pattern.

Detailed description of the invention

Embodiment one, as shown in Figure 1 to Figure 3,

A kind of damping trailer tire, entirety is annular arrangement tire, integral with hub-shaped, wherein, wheel hub is made up of inside and outside steel ring and the Flexible Connector be clamped between inside and outside steel ring, and the surface of outer rim is provided with rubber layer or layer of polyurethane, forms tire construction.

Particularly, interior steel ring 1 diameter is less, and the outside face of interior steel ring 1 is provided with some draw-in grooves, and draw-in groove is strip, is circumferentially evenly arranged, and draw-in groove is cone tank, for the installation of Flexible Connector 3.Outer rim 2 diameter is comparatively large, and the inside face of outer rim 2 is provided with some draw-in grooves, and draw-in groove is strip, is circumferentially evenly arranged, and draw-in groove is cone tank, for the installation of Flexible Connector.

Flexible Connector 3 is Z-shaped punching press steel part, itself there is certain elasticity, there is in Z-shaped turning point prolongation afterbody 31 outwardly, the existence of this prolongation afterbody can improve the intensity of Flexible Connector by actv., especially the intensity of turning point, two ends are that interface is plugged in draw-in groove respectively, and are that inside and outside steel ring connecting portion uses welding process both to be linked into an integrated entity, and form a kind of fixed relationship.Have a kind of elasticity on the whole, in the good situation of general road conditions, Flexible Connector is substantially indeformable, when road conditions are poor, rely on the elastic deformation of Flexible Connector and layer of polyurethane, can increase cushion characteristic, improve overall elasticity.

Be provided with the groove 21 of some annulars at the outside face of outer rim 2, groove is along the distribution of outside face circumference, and surface coverage one deck rubber layer or layer of polyurethane outside, adopt sulfuration process to design and produce.

Further, as Fig. 4, perching knife is used to shovel out hamulus 22 one by one at the outside face of outer rim 2, and hamulus is heat-treated, improve the intensity of hamulus, rubber layer and hamulus form occlusion structure poor each other, make with the combination of rubber layer more strong, improve anchoring strength between the two, there is more outstanding effect.

The forming process of above-mentioned hamulus is as follows, first uses pointed cutter---and what perching knife carried out discountinuity roots out operation, forms reversed acanthoid one by one, then heat-treat on the surface of outer rim, improves the intensity of hangnail.

Certainly be provided with on the ring surface of rubber layer 4 and grab ground decorative pattern 41, in rubber layer, grab ground decorative pattern according to tire specification, and carry out thickenings strengthen designing at crown, position, sidewall.

Embodiment two, is with embodiment one difference, and rubber layer have employed and thickeies design, and is provided with anti-side in the two sides of rubber layer and draws projection, and the overall anti-scratch performance of reinforced tire, can avoid the scuffing of the sharp object from side.

Except the technical characteristic described in specification sheets, be the known technology of those skilled in the art.
