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.
