Abstract

The utility model discloses a vacuum tire for a motorcar. The vacuum tire comprises a tread cap (1) at the top, tire beads (2) which are arranged on two sides of the tread cap (1), and tire shoulders (3) which are transited between the tread cap (1) and each tire bead (2), wherein the tread cap (1) and the tire beads (2) are arch-shaped; the inner walls of the tread cap (1) and the tire beads (2) are provided with electric airtight inner face glue (4) and a high density double-layer tire cord (5) in sequence from the inside to the outside; the bottom of each tire bead (2) is slantly arranged in an inner-low and outer-high manner; the inclined angle of the bottom of each tire bead (2) is 14-16 degrees. A lip structure is designed according to the combination diameters of rims of the motorcar, and the combination of the electric airtight inner face glue and the high density double-layer tire cord is adopted at the same time; while the rims are tightly attached, the vacuum tire also has the characteristics of high integral rigidity for tires, better comfort, safety in operation and the like.

Description

Vacuum tire of electric vehicle

Technical field

The utility model relates to battery-driven car, particularly relates to a kind of electric vehicle vacuum tyre.

Background technology

Vacuum tire is tubeless air-inflation tyre, claims again by " low pressure tire " or " air tyre ".Because vacuum tire surface is one deck top-quality rubber, after inflation, appearance tension force increases, and at inside face, forms certain pressure, improved the self-styled ability to cut, once puncture, unlike common tire, gas was all let out in moment, can continue the regular hour, safety while having ensured high speed traveling, therefore vacuum tire is in recent years at motor bike, car, and the use on passenger vehicle, lorry is increasingly extensive, vacuum tire has higher elasticity and resistance to abrasion, and has good adhesive ability and heat dispersion.At present vacuum tire on battery-driven car seldom, mainly because electric vehicle tyre is narrower, good not for the stickiness of battery-driven car vacuum wheel rim, cause after vacuum tyre tread flaking and be difficult to stamp again, simultaneously because vacuum tyre cost is higher, be applied to can bring larger economic pressures on the battery-driven car of low price.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of and the wheel rim good battery-driven car vacuum tire of fitting.

The technical solution of the utility model is as follows: a kind of vacuum tire of electric vehicle, comprise the crown (1) on top and be arranged on the tyre bead (2) of crown (1) both sides, and the tire shoulder (3) between transition crown (1) and tyre bead (2), described crown (1) becomes arcuation with tyre bead (2), it is characterized in that: described crown (1) and tyre bead (2) inwall are from inside to outside disposed with electronic airtight inner face glue (4) and highly dense double-deck cord (5), the bottom of described tyre bead (2) is interior low outer high dip setting, the angle of inclination of the bottom of this tyre bead (2) is 14～16 °.

Adopt the vacuum tire of electric vehicle of said structure, because the bottom of tyre bead is interior low outer high dip setting, and the angle of inclination of the bottom of this tyre bead is 14～16 °, according to battery-driven car wheel rim work, to close diameter design to carry out lip configurations, can be good at wrapping wheel rim, more be difficult to tread flaking, and more easily install after tread flaking.Crown and tyre bead inwall are from inside to outside disposed with electronic airtight inner face glue and highly dense double-deck cord simultaneously, electronic airtight inner face glue has improved the self-styled ability to cut, once puncture, unlike common tire, gas was all let out in moment, can continue the regular hour, the safety while having ensured high speed traveling, the highly dense double-deck cord adopting, make integral body stressed evenly, level and smooth inside, guaranteed carcass integral rigidity.

The arranged outside at described highly dense double-deck cord (5) top has cushion layer (6), and this cushion layer (6) is positioned at crown (1), has improved processing safety, and makes traveling comfort better.

The dual-side of described highly dense double-deck cord (5) all has outside flange, and is surrounded by steel wire (7) in the flange of highly dense double-deck cord (5), and the highly dense double-deck cord of the inside banding of steel wire, makes the laminating of vacuum tyre and wheel rim tightr.

Beneficial effect: the utility model closes diameter design according to battery-driven car wheel rim work and carrys out lip configurations, adopted the combination of electronic airtight inner face glue and highly dense double-deck cord simultaneously, when fitting tightly wheel rim, also there is the features such as tire integral rigidity is strong, traveling comfort better, operation safe.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.

As shown in Figure 1, the utility model comprises crown 1, tyre bead 2, tire shoulder 3, electronic airtight inner face glue 4, highly dense double-deck cord 5, the parts such as cushion layer 6 and steel wire 7, the crown 1 and the tyre bead 2 that is arranged on crown 1 both sides that comprise top, and the tire shoulder 3 between transition crown 1 and tyre bead 2, 2 one-tenth arcuations of described crown 1 and tyre bead, described crown 1 and tyre bead 2 inwalls are from inside to outside disposed with electronic airtight inner face glue 4 and highly dense double-deck cord 5, the bottom of described tyre bead 2 is interior low outer high dip setting, the angle of inclination of the bottom of this tyre bead 2 is 14～16 °, be preferably in the present embodiment 15 °, and the bottom thickness of this tyre bead 2 is 9mm, and this vacuum tyre is by being arranged on valve 8 inflations and the sealing on wheel rim.The arranged outside at described highly dense double-deck cord 5 tops has cushion layer 6, and this cushion layer 6 is positioned at crown 1.The dual-side of described highly dense double-deck cord 5 all has outside flange, and is surrounded by steel wire 7 in the flange of highly dense double-deck cord 5.

The foregoing is only preferred embodiment of the present utility model; not take the utility model as restriction; all any modifications of doing, be equal to the quantity etc. of replacing and improving as change dial framework and benchmark post, within all should being included in protection domain of the present utility model within spirit of the present utility model and principle.
