Abstract
The present invention relates to a solid tyre and a manufacturing method thereof for a circular rim of a pneumatic tyre. The solid tyre has a structure of four hierarchies such as basal glue, transition glue, tyre core glue and tread glue; the present invention has the advantages of high elasticity and good shock absorbing capacity and is difficult to generate a ' layer dropping ' phenomenon and a 'ring slipping' phenomenon. The present invention is suitable for hoisting machinery, medium-size mining machinery, various forklifts, platform trailers, and all Industrial vehicles with a low speed and a medium speed, and high load running or a severe running condition.
Description
The present invention relates to a kind of solid tyre and manufacture method thereof that is used for the air tyre wheel rim.This solid tyre can exchange with the same specification air-inflation tyre, and it is specially adapted to elevator machinery, medium-sized mining machinery, all kinds of fork truck, flat-bed trailer and all needs low-medium speed, high load capacity to travel or the industrial vehicle of driving conditions harshness.This structure that is used for the solid tyre of air tyre wheel rim mainly includes base portion glue, tyre core glue, tread-rubber, carcass plies and bead coil etc.
Known at present, the structure of most solid tyres is made up of carcass and tyre surface.Carcass is made by half elastic caoutchouc of the benefit curtain fiber that contains any distribution, does not have clear and definite hierarchical structure, and one of major defect of this tire is that cushion characteristic is poor, and the stationarity of travelling is had harmful effect.The situation of carcass and tyre surface " delamination " also can appear in this in addition real core tire, this be since carcass different with tyre surface elasticity due to.
A kind of advanced person's that West Germany companies such as " Wo Weika " produces the solid tyre that is used for the air tyre wheel rim, except that tread-rubber, its carcass by
Base portion glue and tire core glue two parts are formed, the structure that tread-rubber, tyre core glue and three levels of base portion glue are promptly arranged, the hardness of base portion glue is higher, tyre core glue has cushion characteristic preferably, because base portion glue directly links to each other with tyre core glue, both performances differ bigger, be difficult for bonding, so also cause " delamination " phenomenon easily.
Task of the present invention is to provide a kind of real core tire and manufacture method thereof that is used for the air tyre wheel rim, and this solid tyre has higher elasticity, and the slow performance of filling is good, and is difficult for taking place " delamination " and " brush circle " phenomenon.
Accompanying drawing is the section structure scheme drawing of solid tyre of the present invention.
As shown in drawings, real core tire of the present invention, its structure Zhu want the Zu such as You base portion glue 1, transition glue 2, tyre core glue 3, tread rubber 4, triangle rubber, casing ply 6 and wire loop 7 to become.
On the integral structure of tire, between the base portion glue 1 of solid tyre of the present invention and the tyre core glue 3 one deck transition glue 2 is arranged, the percentage elongation of transition glue greater than base portion glue less than tyre core glue, its hardness greater than tyre core glue less than base portion glue, transition glue has the character of transition, and tyre core glue has cushion characteristic preferably.The sizing material composition of base portion glue, tyre core glue and tread-rubber has nothing in common with each other.To tread-rubber, the hardness of glue weakens gradually from base portion glue, is difficult for causing stress concentration.Whole tire has the structure of four levels, layer transition gradually between layer.
The composition of raw materials of preparation base portion glue, transition glue, tyre core glue and tread-rubber is as shown in table 1.
As the instantiation of this prescription, as shown in table 2.
Aspect the tyre bead processing, what the present invention adopted is, anti-package or just wrapping carcass plies 6 outside bead coil 7, and apex strip 5 transition are arranged between bead coil and the carcass plies, make and do not have air admission in the tyre bead, and loosening phenomenon can not take place in bead coil in carcass plies, and whole like this tire force situation just relatively evenly.Slack running fit is adopted in cooperating between solid tyre and the wheel rim, and promptly the well width of tire on tread design, should be considered traction wheel or wheel flutter greater than rim width 2-3 millimeter.If traction wheel, tread contour should have holding power preferably, and will give birth to heat and lack, thermal diffusivity, if wheel flutter, tyre surface should have circumferential pattern or winding pattern.
The manufacture method that is used for the solid tyre of air tyre wheel rim of the present invention is characterized in that providing the composition of raw materials for preparing base portion glue 1, transition glue 2, tyre core glue 3 and tread-rubber 4.This prescription is as shown in table 1, and is as an example of this prescription, specifically as shown in table 2.
Because solid tyre of the present invention has the structure of four levels, transition gradually between layer and the layer is so tire is difficult for taking place " delamination " phenomenon.Because the batching of each layer glue is reasonable, solid tyre has higher elasticity, tear strength and wear resisting property, cushion characteristic is good.New tyre bead processing method makes solid tyre be difficult for taking place " brush circle " phenomenon.The physical and mechanical properties parameter of each layer glue is as shown in table 3.
