Abstract
The invention provides a polyurethane rubber-coated filled solid tire to overcome the problem that insufficient strength of a side rubber layer of a conventional filled solid tire easily leads to scratches of the tire and thus leads to exposure of a filler. The polyurethane rubber-coated filled solid tire comprises, from exterior to interior, a rubber layer and a polyurethane filled inner core, wherein the polyurethane filled inner core is adhered on a wheel hub, and the rubber layer and the polyurethane filled inner core are bonded together. The polyurethane rubber-coated filled solid tire is characterized in that external surfaces of two sides of the rubber layer are respectively coated by a polyurethane coating layer from tire top to tire bottom and the polyurethane coating layers and the rubber layer are integrated into one through vulcanization. According to the invention, superhardness, wear resistance and scratch resistance of the external layer of a conventional filled solid tire are maintained, and the internal matrix of the polyurethane rubber-coated filled solid tire is a polyurethane material, which enables elasticity of the integral tire to be guaranteed to a greatest extent; meanwhile, the polyurethane coating layer is additionally added at a weak position of each of the two sides of the tire so as to form a protective layer.
Description
Technical field
The present invention relates to band tyre technical field, a kind of filled type band tyre specifically using in mine vehicle.
Background technology
Filled type band tyre, is widely used in the occasions such as mine, harbour, and its basic structure comprises rubber layer and filling polyurethane inner core.This kind of inside tires has filling polyurethane thing, so have good traveling comfort, have fabulous shock-absorbing performance when bad ground run, will have good resistance to abrasion, weather resisting property simultaneously.Inner filling polyurethane inner core elasticity is better simultaneously, density is lower, so have, is similar to airtyred travelling comfort.
But also there is its shortcoming, main manifestations is: in order to increase traveling comfort, the thickness of rubber layer is not generally very thick, and the environment for use on mine is more severe, the foreign material such as ground stone, derby easily scratch tire from side, cause the breakage on sidewall, after breakage, cause exposing of weighting material, and then cause scrapping of whole tire.
For this reason, each filled type band tyre manufacturing enterprise, all, in the research and the input that strengthen this respect, to improve the conformability of fill-type tyre, especially strengthens the intensity of the side of filled type band tyre.
Summary of the invention
The object of the present invention is to provide a kind of polyurethane rubber-covered filled type band tyre, keeping on the basis of existing filled type band tyre performance, solve existing filled type solid wheel sidewall rubber layer undercapacity, easily be scratched the problem that causes weighting material to expose, improve service life and the adaptive capacity of filled type band tyre.
The present invention solves the technical scheme that its technical matters takes: a kind of polyurethane rubber-covered filled type band tyre, comprise from the rubber layer and the filling polyurethane inner core that set gradually outside to inside, described filling polyurethane inner core is bonded on wheel nave, and be bonding connection at described rubber layer and filling polyurethane inner core binding site, it is characterized in that, at two side external surfaces of described rubber layer, be coated with respectively from tire and push up to the polyurethane clad at the bottom of tire, described polyurethane clad and rubber layer form one through sulfuration.
Two side external surfaces at described rubber layer are provided with snap close, and are provided with corresponding with it locked groove in described polyurethane clad inner side, between described polyurethane clad and rubber layer, are fastened and connected.
Described snap close is cylindrical snap close.
Described snap close is square snap close.
Described polyurethane clad outside face is smooth side.
The invention has the beneficial effects as follows:
The present invention has retained outer field superhard, the wear-resisting and anti-scratch performance of filled type band tyre, and inner base is polyurethane material, the elastic performance of assurance tire integral body that can great achievement.
In tire both sides, weaker position additionally increases one deck polyurethane clad simultaneously, forms a kind of protective cover.The existence of this clad can effectively prevent the scraping of the hard thing in road surface to tire both sides, forms reasonable protection.Simultaneously because clad is smooth, good antiskid effect.Coated layer by layer by fastening, bonding and sulfuration is coated on tire, after it is scratched, can be removed, and then changes and repairs, and improved the service life of filled type band tyre.Can be widely used in the fields such as tractor-trailer on various industrial vehicles, military vehicle, vehicle for construction, airport, harbour.
Accompanying drawing explanation
Fig. 1 is not for increasing the block diagram of the tire of clad.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is A--A section structure schematic diagram in Fig. 2.
Fig. 4 is sectional schematic diagram of the present invention.
In figure: 1 rubber layer, 2 filling polyurethane inner cores, 3 grab ground decorative pattern projection, 4 polyurethane clads, 5 snap closes, 6 tire tops, at the bottom of 7 tires, 8 wheel hubs.
The specific embodiment
As shown in Figures 1 to 4,
A band tyre, comprises from the rubber layer 1 and the filling polyurethane inner core 2 that set gradually outside to inside.The structure of rubber layer wherein and filling polyurethane inner core and existing filled type band tyre is basic identical, and filling polyurethane inner core is to be directly bonded on wheel hub 8, and rubber layer 1 and filling polyurethane inner core 2 carry out bonding connection.
When actual design, wherein rubber layer thickness thickening design, can improve wear resisting property and load-carrying capacity, be provided with grab ground decorative pattern projection 3 at rubber layer 1 with ground on the ring surface contacting, the lines of grabbing ground decorative pattern projection wherein can design according to actual needs.In outside, rubber layer both sides, be respectively equipped with the snap close of projection, the pattern of snap close is divided into two kinds, a kind of is columniform snap close 5, be arranged on the position near tire top 6, another kind is square snap close, be arranged at the bottom of tire 7 position, snap close and rubber layer are integrated, for being fastened and connected with the locked groove of polyurethane clad 4 inner sides.Polyurethane clad wherein extends to inner ring root from the top of tire, forms omnibearing protection, and outside face is smooth, and anti-scratch effect is better.
The filling polyurethane inner core 2 that a nested section is O type in rubber layer 1.Utilized polyurethane tensile strength high herein, peel strength is high, shock resistance, and rebound resilience is good, and resistance to ag(e)ing is good, and shock-absorbing performance is good, water-fast and acid-proof alkaline good, and bearing load ability is large, the advantage of long service life.
Utilize advantage separately, can produce the effect of super carrying, wear-resisting, anti-scratch, damping and lighter weight.
Between polyurethane clad wherein and rubber layer, be that sulfuration process is connected, at polyurethane clad, suffer after serious damage, also can carry out Replacement and Repair work to it, can effectively reduce use cost.
Except the technical characterictic described in specification sheets, be the known technology of those skilled in the art.
