Embodiment Construction
[0036] The present invention will be further described below in conjunction with specific examples.
[0037] Such as Figure 1-10 As shown, the production method of a one-piece engineering wheel rim, the engineering wheel rim includes an outer retaining ring 11, an inner retaining ring 12, a wheel spoke 13, and a wheel rim 14, which is characterized in that the wheel rim and the inner retaining ring are integrally formed to form part B;
[0038] The outer retaining ring and the spokes are integrally formed to form part A, and part A and part B are welded and fixed, or
[0039] The spoke and part B are integrally formed to form part C, and the outer retaining ring is welded and fixed with part C;
[0040] The spokes are curved spokes, the spokes include a spoke body 131, and the two ends of the spoke body are bent outward to form a bending section 132, and the spokes adopt the design of curved spokes, which improves the support strength of the spokes and the overall support st...

Abstract
The invention discloses a production method of rims of an integrated engineering vehicle. Each rim of the engineering vehicle comprises an outer retainer ring, an inner retainer ring and a wheel flange, wherein the wheel flange and the inner retainer ring are integrally formed to form a part B, the outer retainer ring and a spoke are integrally formed to form a part A, the part A is fixedly weldedto the part B, or the spoke and the part B are integrally formed to form a part C, and the outer retainer ring is fixedly connected with the part C in a welding mode; the spoke is a bent spoke, the spoke comprises a spoke body, the two ends of the spoke body are bent outwards to form a bending section. The rims are manufactured by adopting the method, the wheel flange of each rim is integrally formed with the inner retainer ring, the spoke and the outer retainer ring or the rim are integrally formed, so that the problems of air leakage and the like caused by unqualified products of a lockingring and the outer flange (including the inner retainer ring and the outer retainer ring) are solved, and a design of changing separated-type wheels into whole-type wheels improves technical indexesof roundness, concentricity and jumping.
Description
technical field [0001] The invention relates to engineering vehicle rim technology, in particular to a production method of a one-piece engineering vehicle rim. Background technique [0002] At present, the existing engineering wheel rim usually includes an inner retaining ring 101, an outer retaining ring 102, a wheel rim (100A, 100B), a wheel spoke 103, a lock ring 104, a movable seat ring 105, etc., specifically as Figure 11 As shown, and the inner retaining ring, outer retaining ring, wheel rim, spokes, locking ring, and movable seat are all designed separately, and the wheel rim (100A, 100B) is usually formed by welding in two sections. This design has the following problems: [0003] 1. Problems such as air leakage caused by unqualified lock ring and outer rim (inner retaining ring, outer retaining ring). [0004] 2. Due to the split structure, the requirements for concentricity, roundness, runout and other technical indicators lead to high process requirements, which...
