Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical wheel manufacturing technology, and in particular to a wheel for heavy-duty sprinkler trucks. Background Technology
[0002] Agricultural and forestry sprinkler irrigation vehicles use either spoked wheels or spoked wheels. Heavy-duty sprinkler irrigation vehicles, with their large load-bearing capacity, generally use spoked wheels. However, existing heavy-duty sprinkler irrigation vehicles often use single-plate spoked wheels, which are prone to deformation and have poor load-bearing capacity. Thickening the spokes would significantly increase manufacturing costs and wheel weight. Therefore, it is necessary to provide a new type of wheel for heavy-duty sprinkler irrigation vehicles to address these issues. Summary of the Invention
[0003] This invention provides a wheel for heavy-duty sprinkler trucks, which completely solves the problems of low structural strength, easy deformation, and high manufacturing cost of spoke-type heavy-duty sprinkler truck wheels.
[0004] This utility model adopts the following technical solution: a wheel for a heavy-duty sprinkler truck, comprising a rim and spokes, characterized in that: the spokes comprise two parts, a spoke plate and a composite support plate, the spoke plate being a stepped disc shape, the most concave part of the center of the spoke plate being a central disc; the composite support plate is located outside the central disc of the spoke plate; the outer periphery of the composite support plate is welded to the stepped platform wall on the outer periphery of the central disc of the spoke plate, the central part of the central disc of the spoke plate is provided with an annular groove, the annular groove is provided with a plurality of spoke bolt holes evenly distributed therein, there is a gap between the annular groove and the composite support plate, the composite support plate is provided with support plate bolt holes directly opposite the positions of the spoke bolt holes.
[0005] Furthermore, a stamped top protrusion is provided on the outside of the screw hole of the center disc of the spoke plate.
[0006] Furthermore, the spoke plate is provided with a bending support outer ring on its outer periphery, and the bending support outer ring is welded to the wheel rim.
[0007] This utility model has the following beneficial effects:
[0008] This invention utilizes a composite support plate to support the spoke center disc, significantly improving the structural strength of heavy-duty sprinkler truck wheels. The gap between the annular groove of the spoke center disc and the composite support plate creates an elastic space. Bolts pass through bolt holes to fix the wheel to the axle disc. When the composite support plate and the spoke center disc are clamped by the bolts, the gap acts as a spring-like shock absorber. The top pressure boss forms multiple support points between the spoke center disc and the composite support plate, improving the spoke's resistance to torsion and preventing bolt loosening. The spokes of this invention are formed by stamping, offering advantages such as high structural strength, long service life, and low manufacturing cost. Attached Figure Description

[0013] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific implementation methods, structures, and features of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments. However, the accompanying drawings are for reference and illustration only and are not intended to limit this utility model.
[0014] Example 1: Please refer to Figure 1-3 As shown, this utility model provides a wheel for a heavy-duty sprinkler truck, including a rim 1 and spokes. The spokes consist of two parts: a spoke plate 2 and a composite support plate 3. The spoke plate 2 is a stepped disc shape, with the most concave part at the center of the spoke plate being a spoke center disc 2-1. The composite support plate 3 is located outside the spoke center disc. The outer periphery of the composite support plate 3 is welded to the stepped platform wall on the outer periphery of the spoke center disc. The center of the spoke center disc has an annular groove 2-2, and a plurality of spoke bolt holes 2-3 are evenly distributed within the annular groove. There is a gap between the annular groove 2-2 and the composite support plate 3. The composite support plate 3 has support plate bolt holes 3-1 that are directly opposite the spoke bolt holes. A stamped top pressure boss 2-4 is provided outside the screw holes of the spoke center disc. A bent support outer ring 2-5 is provided on the outer periphery of the spoke plate, and the bent support outer ring is welded to the rim.
[0015] In use, this invention secures the wheel to the axle disc by sequentially passing bolts through the bolt holes 3-1 in the support plate and 2-3 in the spoke center disc. The gap between the annular groove 2-2 of the spoke center disc 2-1 and the composite support plate 3 forms an elastic space. When the composite support plate and the spoke center disc are clamped by bolts, this elastic space acts as a spring-like shock absorber, preventing the bolts from loosening. The spokes of this invention are formed by stamping, and the stamping process utilizes stamping machinery to create the top pressure boss 2-4. The top pressure boss 2-4 forms multiple support points between the spoke center disc 2-1 and the composite support plate 3, improving the elastic support capacity and resistance to torsional deformation of the spoke center disc 2-1 and the composite support plate 3.
[0016] The above-described embodiments are provided to enable those skilled in the art to implement or use this invention. Various modifications to the above embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
