Description
Technical field
It the utility model is related to tire art, more particularly to a kind of low-rolling-resistance polyurethane for self loading trailer
Tire.
Background technology
At present, rising steadily with oil price, people increasingly pay close attention to the fuel consumption of vehicle, while the fuel consumption of vehicle
Become the important indicator that people evaluate a automobile quality.Fuel consumption caused by tire drag accounts for Fuel consumption
14%-17%, and whenever tire drag reduce by 10%, can usually make fuel consumption reduce 1%-2%.Therefore find low
Rolling resistance tyre becomes the target that each automobile vendor is pursued.Tire drag is influenced very by the architectural characteristic of tire
Greatly, thus from the point of view of fuel consumption cost is reduced, just it is highly desirable to and is further changed in terms of low-rolling-resistance
Into also just needs are improved the tire construction that oneself has to realize the low oil consumption demand of automobile.
The content of the invention
The utility model is directed to the problems of the prior art, there is provided a kind of low-rolling-resistance for self loading trailer gathers
Urethane tire.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：
A kind of low-rolling-resistance pu tire for self loading trailer, a kind of low rolling for self loading trailer hinder
Power pu tire, it includes wheel hub, cover tire and support spring, and the tyre surface of cover tire is included in polyurethane tire superficial layer, polyurethane
Interbed, the density of polyurethane surface surface layer are more than Polyurethane Interlayer, and polyurethane surface surface layer is internally provided with the first steel wire reinforcement net, gather
Urethane intermediate layer inner wall is additionally provided with the supporting steel frame of elasticity, and supporting steel frame includes the supporting rack being bonded with Polyurethane Interlayer inner wall
And the retainer plate on supporting rack is fixed on, whole section of retainer plate surrounds a circle, and one end of support spring is fixed on retainer plate, branch
The support spring other end is fixed on the excircle of wheel hub, and support spring is uniformly arranged along wheel hub excircle.
Preferably, forming accommodating cavity between retainer plate and supporting rack, hard filler is equipped with accommodating cavity.
Preferably, wheel hub includes the outer ring of annular, the both sides of outer ring are equipped with bearing support, and bearing support is equipped with multiple mitigations
Hole.
Preferably, the side of cover tire is equipped with the opening of radial direction, opening can make cover tire side by fold so as to pacify from side
Fill supporting steel frame.
The utility model employs above scheme and has the advantages that：
The utility model is equipped with lightening hole on wheel hub, alleviates the weight of whole wheel；By setting two layers of difference close
The layer of polyurethane of degree also mitigates the weight of cover tire while enough wear-resisting properties are provided；Using polyurethane cover tire；With more
A support spring substitutes inflatable inner tube, and by reducing steel of the rolling resistance usually by being equipped with polyurethane tire superficial layer
Silk enhancing net and the hard filler set in accommodating cavity ensure that deformation is transferred to support bullet by load wagon in use
At spring so that tyre surface deformation quantity diminishes, and is improved more than and is realized tire in terms of these three in material, deformation, weight
Reduce the purpose of resistance.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of cover tire.
Reference numeral is described as follows：1-cover tire, 11-polyurethane tire superficial layer, 12-steel wire reinforcement net, 13-poly- ammonia
Ester intermediate layer, 14-supporting steel frame, 141-supporting rack, 142-retainer plate, 2-wheel hub, 3-support spring, 4-outer ring, 5-
