Abstract

The invention discloses a wheel rim of a heavy-load engineering vehicle and a production method for the wheel rim of the heavy-load engineering vehicle, which belong to the technical field of engineering vehicle wheels. The wheel rim of the heavy-load engineering vehicle comprises an inner rim, a retainer ring, a lock ring, a lock groove ring and a tube, which are integrally assembled. One end of the tube is connected with the inner rim while the other end of the tube is connected with the retainer ring, the cross section of the inner rim is L shaped and comprises a vertical rectangular section, one lateral angle of the upper end of the vertical rectangular section is arc shaped, the lower portion of the vertical rectangular section extends to one side of the arc-shaped lateral angle to form a horizontal rectangular section, and the upper end face of the horizontal rectangular section is a slope. The cross section of the retainer ring is irregularly rectangular and consists of a similar rectangular section and a right-angled trapezoidal section which is integrally connected with the lower side of the similar rectangular section, and a lateral angle of the upper side of the similar rectangular section is arc shaped. Compared with the prior art, the wheel rim of the heavy-load engineering vehicle has the advantages that strength is improved by about three times, production energy consumption is reduced by 10-15%, the problems of breakage of the rim root and deformation of the wheel rim of the heavy-load engineering vehicle are thoroughly solved, and accordingly running safety of the heavy-load engineering vehicle is guaranteed.

Description

technical field [0001] The invention relates to an engineering wheel and a manufacturing method thereof, in particular to a heavy-duty engineering wheel rim and a manufacturing method thereof, and belongs to the technical field of engineering wheels. Background technique [0002] Over the years, heavy-duty engineering wheel rims have been manufactured by using common automobile wheel rim steel or welded with plate rings, and then hot-pressed and formed. Its structure is as follows: figure 1 shown; but due to the harsh working conditions of heavy-duty engineering vehicles, especially the working load of the wheels of heavy-duty engineering vehicles exceeds the working load of automobile wheels, the deformation of the wheel rim 1 and the fracture of the rim root 2 often occur, directly affecting to the safe operation of the car. [0003] In order to alleviate the above problems, technicians use thicker plates, perform ring gardening, welding and hot pressing to strengthen the...
