Abstract

The utility model discloses a modified structure of a solid tire. An annular groove is arranged on the outer circumference of the solid tire, two sides of the groove are in symmetric outwardly-bent arc shapes, and the two outer lateral faces of the solid tire also form arc faces corresponding to the arc shapes of the two sides of the groove, so that the periphery of the solid tire is divided into two symmetric tire pieces with semi-crescent sections. The semi-crescent tire pieces are large in deformation, are capable of deforming and avoiding so as to generate no severe jump when pressing obstacles, and thereby the solid tire is fine in comfort.

Description

A kind of structure-improved of band tyre

Technical field

The utility model relates to a kind of tire, refers to a kind of structure-improved of band tyre especially.

Background technology

Tire generally is divided into air tyre and solid tyre, and air tyre is exactly our common air-inflation tyre, and solid tyre then often is the solid construction of being made by foaming material or other rubber material.Tire all is the annular solid with certain radial width and axial width, and its inner ring face cooperates the complete wheel of formation with wheel hub, and its outer ring anchor ring then is middle outstanding both sides convergent cambered surfaces.The tire of this structure travels on flat ground surface, has good comfort.If but travel uneven or when having the ground of rubble, then can produce and beat or deflection.For gas filed air core tyre, because the elasticity of tire is bigger, it relies on the elastic deformation of tire itself can absorb certain shaking force, thereby alleviates the amplitude of beating.But,, therefore when meeting with obstruction thing, will produce bigger beating because the space of its elastic deformation is limited for band tyre.

Shown in Figure 1A to Fig. 1 D, promptly showed the scheme drawing that generation was beated when existing band tyre front met with obstruction thing.When the dead ahead of tire met with obstruction thing 3, the central authorities of tire pushed down encumbrance 3, were subjected to the effect of top pressure, and encumbrance 3 makes tire produce bob, shown in arrow among the figure.

Shown in Fig. 2 A to Fig. 2 D, showed that existing band tyre produces the scheme drawing of beating when wherein a side meets with obstruction thing.When the place ahead of tire one side met with obstruction thing 3, encumbrance 3 was lived in a side pressure of tire, was subjected to the effect of top pressure, encumbrance 3 make tire produce to tiltedly go up to beat, shown in arrow among the figure.

This shows that the band tyre on conventional arched surface has the big defective of the amplitude of beating when travelling on rough road surface.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of structure-improved of band tyre, and it can increase the comfort level of running car when uneven road surface.

For solving the problems of the technologies described above, technical solution of the present utility model is:

A kind of structure-improved of band tyre, the excircle of this band tyre is provided with a loop groove, the dual-side of this groove is the arc of the outside bending of symmetry, the arc of the relative groove dual-side of two lateral surfaces of this band tyre also forms arcwall face, thereby with the periphery of the band tyre tire lobe that to be divided into two cross sections of symmetry be half moon.

The described band tyre two halves formula structure that axial central authorities separate of serving as reasons.

After adopting such scheme, because the utility model is arranged to the outer peripheral edges of band tyre two tire lobes of half moon, form groove between two tire lobes, when travelling uneven or when the road surface of rubble is arranged, outstanding road surface or small crushed stone can directly pass through in groove, in addition, the carcass tension deflection of the relative Traditional bulk structure of half moon structure is big, during for big encumbrance, do not produce but tire lobe elasticity is stepped down and acutely to beat, when only one-sided when pushing encumbrance, this side distortion is stepped down, opposite side also can normally roll, so also can not influence traveling comfort.

In addition, two-piece type half moon tire described in the utility model also has following advantage:

1, perfect heat-dissipating: owing to form groove in the middle of the two lobe formula tires, increased the area of contact with air, good heat dissipation is fit to more speed; And traditional band tyre is owing to all be solid, easily heat build-up in the middle of its carcass during walking, thus influence performance.

2, earth-grasping force is stronger: the two lobe formula tires that the identical pattern depth of width is also identical when zero load are compared with traditional band tyre, because after the load, the traditional relatively band tyre deflection of described two lobe formula tires is a lot of greatly, therefore after the load, two lobe formula tires are more a lot of greatly than traditional band tyre with width after ground contact, make its with ground-surface effective area of contact change greatly, so earth-grasping force is stronger, even on rainy day, travel when smooth slope ground, do not have the phenomenon of skidding yet.

3, because under equal conditions, described two lobe formula tires are stronger than traditional band tyre earth-grasping force, so when identical earth-grasping force, described two lobe formula tires just can be provided with the more shallow decorative pattern of the degree of depth, even decorative pattern need be set, when the rainy day, water is difficult for amassing in the zanjon of decorative pattern like this, and avoids forming the phenomenon of outside water spray.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

What the utility model disclosed is a kind of structure-improved of band tyre, as shown in Figures 3 and 4, is preferred embodiment of the present utility model.The excircle of described band tyre 1 is provided with a loop groove 11, the dual-side 12 of this groove 11 is the arc of the outside bending of symmetry, in addition, the arc of relative groove 11 dual-sides 12 of two lateral surfaces of this band tyre 1 also forms arcwall face 13, thereby with the periphery of the band tyre 1 tire lobe 14 that to be divided into two cross sections of symmetry be half moon.Described band tyre 1 promptly constitutes complete wheel cooperate installation with wheel hub 2 after.

Described band tyre 1 can be integral structure, also can be two halves formula structure.Shown in Fig. 5,6, be the structure of wherein half tire of two halves formula band tyre, it is in the axial central authorities of band tyre 1 with tire in two.The purpose of doing like this is: because described groove 11 is for to present tapered shape from its open end to the bottom, its bottom is narrower, is easy to assemble dust or handstone, is arranged to after the two halves formula tire, and only need separately can conveniently clean both dismountings.

Band tyre structure described in the utility model, when travelling on uneven or road surface that rubble is more, handstone or outstanding road surface can directly be passed through in the groove 11 of band tyre 1.In addition, because formed two half moon tire lobes 14 structure in the form of sheets on band tyre 1, its elasticity is bigger, when pushing down obstacle or outstanding road surface, can form bigger elastic deformation, beat tempestuously thereby avoid producing, therefore described band tyre structure has the good advantage of traveling comfort.

The wheel that described band tyre 1 is installed is when meeting with obstruction thing, and concrete state description is as follows:

Shown in Fig. 7 A to Fig. 7 F, when encumbrance 3 is in the middle of band tyre 1, and encumbrance 3 diameters are greater than groove 11 internal diameters, be subjected to top pressure effect, about 3 two tire lobe 14 elastic deformations of encumbrance and stepping down to both sides, thus make wheel can not produce bob tempestuously, and traveling comfort is good; And cross encumbrance 3 when cartwheel roll, encumbrance is under tire the time, its will by about the effect of two tire lobe 14 restoring forces extrude.

For another example shown in Fig. 8 A to Fig. 8 F, when encumbrance 3 when band tyre 1 is one-sided, be subjected to top pressure effect, monolithic tire lobe 14 elastic deformations and upwards stepping down, 14 normal rollings of another sheet tire lobe can not produce beating of oblique upper, so do not influence traveling comfort.
