Description
Technical field
The utility model belongs to tire art, more particularly to agricultural machinery tire, and in particular to a kind of non-maintaining wheel of agricultural machinery
Tire.
Background technology
Agricultural machinery, refer to the general designation of the various machines used in agricultural production, general classification by use.As soil cultivating machine,
Plantation and fertilizer machinery, plant protection mechanism, crop harvesting machine, animal husbandry machinery and agricultural product processing machinery etc..Because
Agricultural machinery is limited using road conditions, and tire unavoidably understands bruising to sharp objects such as stone, glass or plant spines in the process of moving,
Tire tread or sidewall can be made to puncture or jolt, extrude and cause the sidewall crimp, reduce the tyre surface of the agricultural tyre with
The contact area on ground, easily agricultural machinery fuselage is swung, so as to have influence on agricultural machinery normal use.
In addition, also as, sidewall is provided with many raised treads to thicken the thickness of tyre surface, institute unlike tyre surface
So that sidewall is thinner and is more easy to be scratched by hard thing, and the tire after sidewall is scratched needs to repair and safeguard in time and frequently, increase
The use cost of consumer.
Based on this, applicant considers that design is a kind of simple and reasonable, and the agricultural machinery that can lift agricultural machinery cruising characteristic is used
Non-maintaining tire.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is：How a kind of knot is provided
Structure advantages of simple, the non-maintaining tire of the agricultural machinery of agricultural machinery cruising characteristic can be lifted.
In order to solve the above-mentioned technical problem, the utility model employs following technical scheme：
A kind of non-maintaining tire of agricultural machinery, including tire body and wheel rim, the tire body assembling are fixed on the wheel
On rim, it is characterised in that：The tire body profile height is D, and the wheel rim radius is that R, R and D ratio are 1.25 to 5.
Ratio on existing tire between " wheel rim radius " and " tire body profile height " is usually 0.5 to 1.1.
