Semi-Trailer Aluminum Alloy Wheel Hub

Technical Field

The utility model relates to a semi-trailer wheel hub, in particular to a semi-trailer aluminum alloy wheel hub.

Background Technology

A wheel hub, also known as a wheel rim, is an important component of a semi-trailer. The “wheel hub” and the “tire” are two completely different components. The “tire” refers to the rubber portion of the wheel assembly, which itself is flexible, while the cylindrical component supporting the inner contour of the tire and mounted on the axle is called the wheel hub.

With the increasing demand for lightweight design, aluminum alloy materials are being increasingly used for semi-trailer wheel hubs. Aluminum alloy wheel hubs have the advantages of light weight, high safety, and high load-bearing capacity. However, existing aluminum alloy wheel hub structures still adopt traditional steel-structure design concepts, which are not conducive to lightweight optimization and do not meet the design requirements of aluminum alloy wheel hubs.

Summary of the Utility Model

To solve the above problems, the utility model provides a semi-trailer aluminum alloy wheel hub with a more optimized structural design.

To achieve the above purpose, the utility model adopts the following technical solution:

A semi-trailer aluminum alloy wheel hub comprises a wheel hub body and wheel spokes. The wheel hub body is provided with an axial central through hole for mounting bearings and an axle. A double-sided recessed ring is arranged on the outer side of the axial central through hole. Brake drum mounting holes are arranged on the double-sided recessed ring, while a brake drum mounting seat is arranged on the opposite side of the double-sided recessed ring to provide reinforcement. The wheel spokes are arranged on the outer side of the recessed ring, and axle connection holes are provided on the wheel spokes.

Further, reinforcing rib plates are arranged between the brake drum mounting holes, and the reinforcing rib plates include long rib plates and short rib plates.

Further, the number of brake drum mounting holes is set to ten. Every two adjacent brake drum mounting holes form one group, constituting five groups in total. The reinforcing rib plate between each group of brake drum mounting holes is a long rib plate, while the reinforcing rib plate within each group is a short rib plate.

Further, reinforcing ribs are respectively arranged at the front and rear of the brake drum mounting seat. The brake drum mounting seat is connected to the outer circumference of the axial central through hole and the outer side of the double-sided recessed ring through the reinforcing ribs.

Further, lightweight cutouts are arranged on the outer circumference of the wheel spokes to further reduce the overall weight.

Further, a recessed area is arranged inside the lightweight cutouts to reduce weight while maintaining the overall structural integrity.

Beneficial Effects

Compared with the prior art, the utility model has the following beneficial effects:

The arrangement of the double-sided recessed ring and the lightweight cutouts reduces the weight of the aluminum alloy wheel hub, while the reinforcing rib plates and reinforcing ribs ensure that the structural strength still satisfies design requirements during weight reduction, thereby meeting lightweight design requirements.

Detailed Description

To enable those skilled in the art to better understand the technical solution of the utility model, the utility model is further described below in conjunction with Figures 1 and 2 and specific embodiments.

As shown in Figures 1 and 2, the semi-trailer aluminum alloy wheel hub comprises a wheel hub body 1 and wheel spokes 2. The wheel hub body 1 is provided with an axial central through hole 3 for mounting bearings and an axle. A double-sided recessed ring 4 is arranged on the outer side of the axial central through hole 3. Brake drum mounting holes 5 are arranged on the double-sided recessed ring 4, and a brake drum mounting seat 6 is arranged on the opposite side of the double-sided recessed ring 4 for reinforcement. The wheel spokes 2 are arranged on the outer side of the double-sided recessed ring 4, and axle connection holes 7 are arranged on the wheel spokes 2.

Further, reinforcing rib plates are arranged between the brake drum mounting holes 5, including long rib plates 8 and short rib plates 9.

Further, the number of brake drum mounting holes 5 is ten. Every two adjacent brake drum mounting holes 5 form one group, constituting five groups in total. The reinforcing rib plate between each group is a long rib plate 8, while the reinforcing rib plate within each group is a short rib plate 9.

Further, reinforcing ribs 10 are respectively arranged at the front and rear of the brake drum mounting seat 6. The brake drum mounting seat 6 is connected to the outer circumference of the axial central through hole 3 and the outer side of the double-sided recessed ring 4 through the reinforcing ribs 10.

Further, lightweight cutouts 11 are arranged on the outer circumference of the wheel spokes 2 to further reduce the overall weight.

Further, recessed areas 12 are arranged inside the lightweight cutouts 11 to reduce weight while maintaining the overall structural integrity.

Any technical solution designed by those skilled in the art based on the technical inspiration of the utility model and capable of achieving the above technical effects shall fall within the protection scope of the utility model.
