second face

11,12 outer peripheral edges.

Rolling touch face 14 is kiss the earth rollably, is in order to be mounted in the rotating shaft (figure does not show) and set up hole 16, to drive band tyre 100 rotations.

Band tyre 100 is general normal to be used on the engineering facility of some important requirement supporting capacity and other vehicles, on hand barrow, wheelchair, battery-driven car, because of band tyre 100 can provide the general bigger supporting capacity of air-inflation tyre, but make therefore that also the traveling comfort of band tyre 100 is not so good as general air-inflation tyre.

In order to improve the traveling comfort of band tyre 100, usually on its first and

second face

11,12, be concaved with several depressions 18 around central axis 13.Number depressions 18 are located on and set up 14 in hole 16 and rolling touch face, by the design of depression 18, have some cushion spaces when making band tyre 100 be subjected to impacting, and then increase some traveling comforts.But when on band tyre 100 too much depression 18 being set, though can make band tyre 100 more comfortable, the overall construction intensity of band tyre 100 is also therefore destroyed, must consider with overall construction intensity so the quantity of depression 18 is set.

Each depression 18 is for to define form cylindric by annular sidewall 181 and diapire 183, and its opening 185 is to be positioned on first or two 11,12.

And when (figure does not show) installing band tyre 100 on car body, car body makes car body more comfortable when travelling by the depression 18 on the band tyre 100, because when band tyre 100 roll extrusion during in rough road surface, the cushion space that depression 18 on the band tyre 100 can provide car body weight to be squeezed in band tyre 100, thereby the vibrations degree of attenuating car body.Band tyre 100 can present situation as shown in Figure 3 when being squeezed, because each depression 18 is near first and

second face

11,12 place's broads, so most deformation all betides near first and

second face

11,12 places, and less along the direction deformation quantity of the radial centre lines 141 of vertical centre axis 13, so its traveling comfort still remains to be improved.And dwindle because of the opening 185 of depression 18, and sidewall 181 and diapire 183 can be pullled, this moment is most of because of pushing the junction that the stress that is produced can concentrate on sidewall 181 and diapire 183, because the angle of sidewall 181 and diapire 183 junctions is sharp-pointed than other positions, under long-term use, sidewall 181 and diapire 183 junctions can constantly be pullled and be discharged, making sidewall 181 and diapire 183 junctions can produce the crack damages, therefore existing band tyre 100 often can't be taken into account the service life of band tyre 100 in pursuing under the comfortable flexibility.

The specific embodiment

As shown in Figure 4, the utility model band tyre 600 integral body are cylindric, and it has around horizontal center line axis 66 and defines the cylindrical surrounding wall 60 that sets up hole 65.

Surrounding wall 60 has upright first 61, in contrast to first 61 second 62 and connect face 63 around central axis 66 and the rolling that is connected between first and second face 61,62 outer peripheral edges.

Rolling touch face 63 is kiss the earth rollably, is in order to be mounted in the rotating shaft (figure does not show) and set up hole 65, to drive band tyre 600 rotations.

Form respectively on first and second face 61,62 several toward second, first and second depression 67,68 of extending of one side 62,61 directions, several first and second depressions 67,68 are to be provided with at interval around central axis 66 equal angles, and are positioned at rolling touch face 63 and set up 65 in hole.Several first and second depressions 67,68 are the corresponding setting of level, promptly the position that is arranged on first 61 of first depression 67 is identical with the position that second depression 68 is arranged on second 61, and the degree of depth of each first and second depression 67,68 is no more than the radial centre lines 631 of vertical centre axis 66; Also can make several first depressions 67 and several second depression, 68 interlaced settings, and not be positioned on the same horizon, and the degree of depth of each first and second depression 67,68 can surpass the radial centre lines 631 of vertical centre axis 66.The environment that quantity system uses according to tire size, loading and institute's desire that is provided with of several first and second depressions 67,68 decides.

As Fig. 4, shown in Figure 5, have first gradual expansion in first and second depression 67,68, progressively again fold general expansion section 671,681 spherical in shape, make that the internal face 673,683 of first and second depression 67,68 is made of gentle curved surface.And when the utility model band tyre 6 00 is squeezed, in first and second depression 67,68, can present interim buffering phenomenon, because of first and second depression 67,68 structures are the same, so be illustrated with second depression 68.

When band tyre 600 is squeezed, the strength of extruding can be done the compression of F/s prior to the widest part of arrow 71 indications to second depression 68, and the design of 681 internal faces 683 by the expansion section, and then the squeeze force that will be positioned at arrow 71 places is disperseed by the curved surface along internal face 683 around the arrow 71, then can be done the compression of subordinate phase as arrow 72 places to second depression 68 by the strength after disperseing, certainly the strength of this extruding has been carried out and has disperseed, so the compression degree of second depression 68 can be slowed down in arrow 72 places, last remaining squeeze force can be done the compression of phase III in arrow 73 places to second depression 68, so when band tyre 600 is squeezed, can have buffering three times in second depression 68, be unlikely and make the stressed too strong of second depression, 68 internal faces 683, and then the service life of promoting second depression 68, and when second depression 68 is squeezed, the design of 681 internal faces 683 by the expansion section, make squeeze force can too not concentrate on a certain position or a certain zone, under long-term use, can not be easy to generate the crack as the band tyre of commonly using 100 and damage, especially to promoting many service life of the utility model band tyre 600.

And because close first and second face 61,62 of narrower place system of first and second depression 67,68, and broad place system is positioned at inside, so when pressurized, most deformation meeting betides than near line of centers 631 places, therefore has preferable traveling comfort.

As shown in Figure 6, also form respectively on first and second face 61,62 of the utility model band tyre 600a several toward second, third and fourth depression 64,69 of extending of one side 62,61 directions, several third and fourth depressions 64,69 are to be provided with at interval around central axis 66 equal angles, and are positioned at rolling touch face 63 and set up 65 in hole.Several third and fourth depressions 64,69 are the corresponding setting of level, promptly the position that is arranged on first 61 of the 3rd depression 64 is identical with the position that the 4th depression 69 is arranged on second 61, and the degree of depth of each third and fourth depression 64,69 is no more than the radial centre lines 631 of vertical centre axis 66; Also can make several third and fourth depression 64,69 interlaced settings, and not be positioned on the same horizon, and the degree of depth of each third and fourth depression 64,69 can surpass the radial centre lines 631 of vertical centre axis 66.The environment that quantity system uses according to tire size, loading and institute's desire that is provided with of several third and fourth depressions 64,69 decides.

Have first gradual expansion in third and fourth depression 64,69 equally, progressively again fold general expansion section 641,691 spherical in shape, just continue to be concaved with semicircle space 643,693 in third and fourth depression 64,69 mutual close sides, this semicircle space 643,693 can be when third and fourth depression 64,69 be squeezed, and its phase III compression produces simultaneously and born by 641,691 both sides, expansion section; More can make band tyre 600 reach comfortable purpose and increase the service life.

As Fig. 7, shown in Figure 8, under identical loading and environmental conditions, the utility model and general pneumatic tyre and the loading of commonly using band tyre are during with the deflection comparison, no matter vertically or horizontal deflection, the utility model all is between general pneumatic tyre and the band tyre commonly used, can illustrate that traveling comfort of the present utility model can more approach general pneumatic tyre by existing band tyre; Certainly the utility model is offered the cooresponding depression of quantity with the band tyre of commonly using, so both are suitable for the external force that just can bear.

As shown in Figure 9, during for the heat test of the utility model and the band tyre commonly used, the temperature that band tyre the produced system of commonly using through the use lower limit of identical time is higher than the utility model band tyre, and temperature is got over the faster accelerated weathering of Gao Zehui, that is to say that the service life of the band tyre of commonly using is short than the utility model.
