Abstract
The utility model relates to a novel tractor drive tire with the specification from 9.0 to 20, which is composed of a friction surface (1), an inner tire chamber (2), a rim (3) and a wheel drum assembling opening (4). The utility model has the technical characteristics that the cross size C is from 220 to 240 mm; the outer diameter A is from 900 to 940 mm; the inner diameter B is from 512.4 to 513.2 mm; the diameter D of an inner edge is from 177.56 to 178.04 mm.
Description
The utility model relates to a kind of tractor driving wheel tire, particularly 17～28 horsepowers tractor driving wheel tire.
Demand according to market, the mating power of middle-size and small-size trac. is with initial 12 horsepowers, 15 horsepowers, develop into present 17 horsepowers and 20 horsepowers, for the mating power that can make trac. is fully played, the architecture quality of necessary corresponding increase trac., or thereby the width that increases the tire on the drive wheels of trac. increases adhesive ability with the area of contact that increases between trac. and the ground, reduce the slippage rate of tire, and the increase of tractor structure quality, certainly will to increase the productive costs of trac. greatly, thereby be to select a kind of tire on the drive wheels of broad in the best method of the trac. tractor parameter not being done big change and being brought into play tractor power better, in GB2979-91 agricultural tyre series tractor driving wheel tire standard, often select 9.5-20 and 7.5-20 for use, and the tire of this specification of 9.5-20, though the section broad, external diameter is big, the cost height, and the tire outside diameter of this specification of 7.5-20 is little, and is inapplicable than high-power.Thereby in current required standard, there is not a kind of desirable tire on the drive wheels to satisfy the needs of reality.
The purpose of this utility model be to provide a kind of than more economical in the existing tractor driving wheel tire standard, better bring into play the tractor driving wheel tire of tractor power.
The purpose of this utility model is achieved in that and promptly designs the tractor driving wheel tire that a kind of new spec is 9.0-20 that this tire adopts the version of knowing altogether, under existing wheel hub diameter unmodified situation, increases section width C, C=220～240mm.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Below in conjunction with accompanying drawing technical characterictic of the present utility model is specified, this tire is made up of friction face (1), inner tube of a tyre chamber (2), wheel rim (3), wheel hub installation opening (4), is a whole formation type structure, its technical parameter such as following table:
| Tire size | Basic specification | Behind the new inflation of tire of principal parameter | Other parameter | |||
| The number of plies | Standard rim | Section width C | Outer diameter A (K-1 decorative pattern) | Internal diameter B | Inner edge diameter D | |
| ?9.0-20 | ?6 | ?W7 | ?220～240 | ?900～940 | ?512.8±0.4 | ?177.8±0.24 |
External diameter A=900～940mm in the utility model, section width C=220～240mm.Internal diameter B=512.8 ± 0.4, inner edge diameter D=177.8 ± 0.24mm.
After this tire trial assembly, by making traction test, its tractive force limit improves 20% than the trac. of 7.5～20 tires of same type machine dress, and each saves production cost 50 yuan than the tire of 9.5～20 specifications.
