Description

Technical Field

[0001] This utility model relates to the field of mechanical wheel manufacturing technology, and in particular to a cast spoke wheel for heavy-duty tractors. Background Technology

[0002] Tractor traction is primarily generated through the friction between the tires and the ground. To increase tractor traction, one can increase the tire area or add wheel counterweights. Existing heavy-duty tractors, with limited tire width, mostly increase traction by adding wheel counterweights. Current heavy-duty tractor counterweight wheels often use bolted weights mounted on ordinary wheel spokes. This added weight requires drilling holes to fix it to the spokes, leading to installation difficulties, reduced wheel structural strength, and difficulty in adjusting wheel balance. Therefore, it is necessary to provide a new type of cast-spoke wheel for heavy-duty tractors to solve these problems. Summary of the Invention

[0003] This utility model provides a cast spoke wheel for heavy-duty tractors, which completely solves the problems of difficulty in installing counterweights on heavy-duty tractor wheels, reduction of wheel structural strength due to counterweight installation, and difficulty in adjusting wheel balance. It has the advantages of high structural strength, easy disassembly and assembly, no need to add counterweights, and applicability to tractors with various wheelbase models.

[0004] This utility model adopts the following technical solution: a cast spoke wheel for a heavy-duty tractor, comprising a rim and spokes, characterized in that: the spokes are disc-shaped cast spokes with a thickness greater than 3.5 cm; multiple rim supports are welded on the inner wall of the rim; the center of the cast spokes is a spoke disc, and the outer periphery is a support connecting ring; the support connecting ring is in a continuous concave-convex bend shape, with the concave surface being the long wheelbase mounting surface and the convex surface being the short wheelbase mounting surface; the center of the spoke disc is an axle mounting hole; bolt holes are provided on the long wheelbase mounting surface, the short wheelbase mounting surface, and the outer periphery of the axle mounting hole.

[0005] Furthermore, the length of the rim bracket is less than the length of the groove formed by bending the bracket connecting ring, so that the rim bracket can be embedded in the groove formed by bending the bracket connecting ring.

[0006] Furthermore, the spoke disc is provided with a number of casting assembly holes.

[0007] This utility model has the following beneficial effects:

[0008] This invention employs thickened cast wheel spokes, solving the problem that tractor wheel spokes formed by stamping steel plates require the addition of counterweights, while thick steel plates cannot be stamped into shape. The bracket connecting ring of this invention features continuous concave and convex bends, forming mounting surfaces for long and short wheelbases. When combined with the wheel rim bracket, it can accommodate tractors with different wheelbases. The cast wheel spoke structure of this invention has high strength; a single 80cm diameter spoke can weigh over 250kg, improving wheel weight distribution and effectively enhancing tractor traction.

[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 cast spoke wheel for a heavy-duty tractor, including a rim 1 and spokes 2. The spokes 2 are disc-shaped cast spokes with a thickness greater than 3.5 cm. Multiple rim supports 3 are welded to the inner wall of the rim 1. The center of the cast spokes is a spoke disc 2-1, and the outer periphery is a support connecting ring 2-2. The support connecting ring is a continuous concave-convex bend, with the concave surface being the long wheelbase mounting surface 2-3 and the convex surface being the short wheelbase mounting surface 2-4. The center of the spoke disc is an axle mounting hole 2-5. Bolt holes 4 are provided on the long wheelbase mounting surface, the short wheelbase mounting surface, and the outer periphery of the axle mounting hole. The length of the rim support 3 is less than the length of the groove formed by the bend of the support connecting ring, allowing the rim support to be embedded in the groove. Several cast assembly holes 5 are provided on the spoke disc.

[0015] In use, this invention involves first rotating the installation angle of the cast wheel spokes to align the rim bracket 3 with different wheelbase mounting surfaces. The long wheelbase mounting surface is bolted to the rim bracket 3, suitable for long wheelbase tractors, while the short wheelbase mounting surface is bolted to the rim bracket 3, suitable for short wheelbase tractors. The cast wheel spoke structure of this invention has high strength; a single 80cm diameter spoke can weigh over 250kg, improving wheel weight distribution and effectively increasing tractor traction. During the casting process, the wheel weight can be slightly adjusted by changing the size of the casting assembly holes 5 on the spoke disc.

[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.
