Description

A kind of band tyre

Technical field

The utility model designing tyre field, is specially a kind of band tyre.

Background technology

Band tyre is a kind of industrial tyre being applicable to low speed, high capacity operational vehicle, is widely used in the field such as flat board and dilatory vehicle in various industrial vehicle, construction machinery and equipment, harbour, airport, railway and big-and-middle-sized industrial and mining enterprises and various cargo handling operation place with its feature such as non-maintaining.Existing tire in use, tire can be subject to the situation of large load pressure unavoidably, tire is often because bearing incessantly pressure and occur irreversible deformation, thus cause tire normally not use, cushion gum layer simultaneously in tire is being squeezed for a long time, in the process of being out of shape, easily cause the internal stress of tire to reduce, easily occur slight crack, cause reduce the service life of tire.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of band tyre being not easy to occur plastic deformation, long service life.

For achieving the above object, the utility model provides following technical scheme: a kind of band tyre, comprise the outermost tread band be connected successively from outside to inside, the cushion gum layer of interlayer and the base portion glue-line of innermost layer, the both sides of described cushion gum layer are respectively equipped with the buffer groove of annular, buffer groove comprises the first cambered surface, second cambered surface and the first arc pressurized bottom surface, first arc pressurized bottom surface respectively with the first cambered surface, second cambered surface is tangent, steel sheet ring is provided with in described base portion glue-line, the width of steel sheet ring is 1:3 with the ratio of the width of base portion glue-line, in steel sheet ring, annular array has some row through holes, often the number of row through hole is 16.

Further, the columns of described through hole is four row, and the aperture of described through hole is 1.8cm-3.6cm.

Further, in described any row through hole, the hole heart distance of two through holes of arbitrary neighborhood is 5.6cm-11.2cm.

Further, the radian of described first arc pressurized bottom surface is 30 degree of-40 degree.

Contrast the deficiencies in the prior art, the beneficial effect that the technical scheme that the utility model provides is brought: 1. the utility model is by the first cambered surface, the second cambered surface and the first arc pressurized bottom surface, and the design that the first arc pressurized bottom surface and the first cambered surface, the second cambered surface are tangent, effectively raise the stress of each junction of cushion gum layer, actv. prevents cushion gum layer from long-term crumpling process, easily occurring the phenomenon generation of slight crack.2. the through hole of the utility model by steel sheet ring designs, makes rubber and steel sheet ring firmly combine, and can be good at protection, support tire, makes tire not easily occur irreversible metaboly.

Fig. 2 is the structural representation of buffer groove.

Fig. 3 is the structural representation of steel sheet ring.

Detailed description of the invention

With reference to Fig. 1-Fig. 3, the utility model is described further.

A kind of band tyre, comprise the outermost tread band 1 be connected successively from outside to inside, the cushion gum layer 2 of interlayer and the base portion glue-line 3 of innermost layer, the both sides of described cushion gum layer 2 are respectively equipped with the buffer groove 4 of annular, buffer groove 4 comprises the first cambered surface 41, second cambered surface 42 and the first arc pressurized bottom surface 43, first arc pressurized bottom surface 43 respectively with the first cambered surface 41, second cambered surface 42 is tangent, steel sheet ring 5 is provided with in described base portion glue-line 3, the stress of rubber in base portion glue-line 5 is affected in order to prevent the width (l) of steel sheet ring 5 excessive, the width (l) of steel sheet ring 5 and the ratio of the width (L) of base portion glue-line 3 are set to 1:3, in steel sheet ring 5, annular array has some row through holes 6, often the number of row through hole 6 is 16.

Tire is when being subject to the pressure of large load, in tire, the buffer groove 4 of cushion gum layer 2 can provide a space cushioned for tire, and the first arc pressurized bottom surface 43 in buffer groove 4 is tangent with the first cambered surface 41, second cambered surface 42 respectively, effectively raise the internal stress of each junction of cushion gum layer 2, actv. prevents cushion gum layer 2 from long-term crumpling process, easily occurring the phenomenon generation of slight crack.

By the through hole 6 of design in steel sheet ring 5, rubber and steel sheet ring 5 are firmly combined, steel sheet ring 5 can be good at protection, support tire, makes tire also not easily occur the phenomenon of plastic deformation when being subject to the pressure of large load.

Further, the columns of described through hole 6 is four row, and the aperture of described through hole 6 is 1.8cm-3.6cm.

Make rubber in the process of building, rubber enters completely, in filling vias 6, and efficient melting together, rubber and steel sheet ring 5 actv. combined, adds the stress of rubber inside.

Further, in described any row through hole 6, the hole heart distance of two through holes 6 of arbitrary neighborhood is 5.6cm-11.2cm.

Through hole 6 is offered in steel sheet ring 5, destroy the inner structure of steel sheet ring 5, reduce the internal stress of steel sheet ring 5, therefore the hole heart distance of two through holes 6 of arbitrary neighborhood in any row through hole 6 is established and to obtain larger than the aperture of through hole 6 2-3 times, the degree that the internal stress effectively reducing steel sheet ring 5 weakens.

Further, the radian of described first arc pressurized bottom surface 43 is 30 degree of-40 degree.

The radian of the first arc pressurized bottom surface 43 can not be excessive, otherwise, when being under pressure, be difficult to effect tire being played to support and resilience, simultaneously, the radian of the first arc pressurized bottom surface 43 can not be too small, otherwise, when being under pressure, be difficult to effect tire being played to buffering, possible inside tires rubber structure is impaired, as preferably: be 30 degree of-40 degree by the radian of the first arc pressurized bottom surface 43.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
