Abstract
The utility model belongs to the technical field of wheels and relates to a polyurethane non-aerated wheel, a wheel shaft installation part is arranged on the middle portion of a wheel hub, a ring-shaped groove is arranged on the outer cylindrical surface, an ellipse solid core tire made of polyurethane materials is shaped on the ring-shaped groove, the solid core tire is higher than the outer cylindrical surface of the wheel hub, and the polyurethane non-aerated wheel has the advantages of long service life, light weight, low cost, excellent elasticity, abrasion resistance of use surface and low return repair rate, and is applicable to various low speed rolling vehicle bodies such as hospital bed pushing vehicles, pushing chairs, supermarket shopping go-cars and the like.
Description
Technical field
The utility model belongs to the wheel technical field, refers in particular to a kind of polyurethane and exempts to inflate wheel.
Background technology
At present, general wheel includes between wheel hub and wheel rim and is provided with spoke, is provided with tire on the outside face of wheel rim, and this class wheel part that comes with some shortcomings: when 1, using for a long time, spoke gets rusty easily, fractures, and influences the stressed distribution of wheel rim; 2, tire includes air-inflation tyre and entity tire: general air-inflation tyre repair rate height, and in use can not avoid tire to be scratched, poke, cause gas leakage, influence is used; General solid tyre quality is heavy, cost is high, poor flexibility, use face are easy to wear, and service life is short.
Summary of the invention
The polyurethane that the purpose of this utility model provides that a kind of long service life, light weight, cost are low, good springiness, use face are not easy to wear and tear, repair rate is low exempts to inflate wheel.
The purpose of this utility model is achieved in that
Polyurethane exempts to inflate wheel, is provided with the wheel shaft installation portion at the middle part of wheel hub, and external cylindrical surface is provided with annular groove, forms the disciform solid tyre of making of polyurethane material on the annular groove, and solid tyre exceeds the hub barrel face.
Above-mentioned wheel hub is the integral structure of making of metallic material.
The inside of above-mentioned solid tyre forms random aperture.
The outstanding compared to existing technology advantage of the utility model is:
The annular cover that solid tyre of the present utility model is made of polyurethane material, long service life, light weight, cost are low, good springiness, use face are not easy wearing and tearing, repair rate is low.
