Description
Technical field
It the utility model is related to tire art, more particularly to a kind of high abrasion pu tire.
Background technology
At present, in the market has two kinds of wear-resistant tyres, general to have the advantages that to exempt to inflate, and is all single layer structure, no Tire ＆ Tube
Point, one kind is solid tyre, it is a kind of be inner side be equipped with groove air tyre, but with cannot be really achieved it is anti abrasive lack
Point；Existing two-ply tyre contact position easily causes stress concentration so as to destroy tire；In addition existing tire assembling is complicated, interior
Tire can not reuse.
The content of the invention
The utility model is directed to the problems of the prior art, there is provided a kind of high abrasion pu tire.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：
A kind of high abrasion pu tire, including the elastic inner tube of a tyre, elastic inner tube of a tyre side middle part, which is equipped with, to be used to install shaft
Mounting hole, the outer surface of the elastic inner tube of a tyre are coated with cover tire, and cover tire forms three bread to the outer surface of the elastic inner tube of a tyre and two sides
Enclose, elastic inner tube of a tyre outer surface is evenly arranged with multiple first protrusions, forms the first groove between adjacent protrusion, the inner surface of cover tire is set
There is second raised and the second groove respectively with the first groove and the first male cooperation.During assembling, cover tire is from the side of the elastic inner tube of a tyre
Face is inserted into, easy to assembly, and carrying out screens by the protrusion between the elastic inner tube of a tyre and cover tire and groove ensures the firm of both connections.
Preferably, the first groove, the first protrusion, the second groove, the second protrusion are arc, the first groove and first convex
Between rising, equal rounding off between the second groove and the second protrusion.The protrusion and groove of arc can reduce between the elastic inner tube of a tyre and cover tire
Problem of stress concentration, improve service life of tire.
Preferably, raised include limiting section, connecting portion, two surfaces of limiting section are the arcwall face being recessed inwardly, limit
Position portion is spherical spacing head and has a diameter larger than the spacing of two opposite arcwall faces.Connecting portion has with limiting section reduces stress collection
In effect, in addition, spacing head can be stuck in the groove of cover tire carry out radial direction it is spacing.
Preferably, being equipped with glue layer between the contact surface of cover tire and the elastic inner tube of a tyre, both are bonded by glue layer.
Preferably, the side of cover tire is equipped with least one hole for injecting glue, hole for injecting glue is located at dog-ear.Gum-injecting port is used for group
The injection of glue during dress.
Preferably, the elastic inner tube of a tyre, made of rubber, cover tire is made of polyurethane.Cover tire made of polyurethane can be with
Improve the wear-resisting property of whole tire.
The utility model employs above scheme and has the advantages that：
The utility model carries out circumferential screens by the male cooperation on the elastic inner tube of a tyre and cover tire, and is carried out by spacing head
Radial direction screens coordinates glue layer to fix both again, fix stably；In addition, camber is set to reduce raised and groove protrusion
Between problem of stress concentration, improve the service life of tire；It is more resistant compared with other materials using cover tire made of polyurethane；Bullet
The property inner tube of a tyre and cover tire are easy for installation, and the hole for injecting glue set on cover tire can very easily carry out injecting glue operation after mounting.
