Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a high-elongation aluminum alloy wheel hub. Background Art

[0002] The automobile wheel hub is a cylindrical metal component inside the automobile tire that is centered on the axle and is used to support the tire. The automobile wheel hub is an important component that connects the brake disc, wheel disc and half axle.

[0003] Existing automobile wheels are generally made of aluminum alloy. The wheel hub generally consists of two parts: a rim and a spoke. The outer end of the spoke is fixed to the inner circumference of the rim. However, the coverage width of the spoke for the rim support is small, resulting in a low overall structural strength of the wheel hub, which reduces the elongation of the wheel hub. Therefore, a high elongation aluminum alloy wheel hub is proposed. Utility Model Content

[0004] The utility model aims to solve the problems of low structural strength and low elongation of automobile wheel hubs in the prior art, and proposes an aluminum alloy wheel hub with high elongation.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high-elongation aluminum alloy wheel hub comprises a rim, a spoke and a mounting seat, wherein the mounting seat is located at the center of the rim, the spoke is arranged between the mounting seat and the rim, and the surfaces of the rim, the spoke and the mounting seat are all sprayed with a protective coating; a reinforcing block is fixedly provided on one side of the connection between the spoke and the rim, a reinforcing rod is fixedly provided on the side wall of the reinforcing block, and one end of the reinforcing rod away from the reinforcing block is fixedly connected to the side wall of the mounting seat.

[0007] Preferably, an axial hole is provided in the middle of the mounting seat, and a plurality of evenly distributed mounting holes are provided around the side wall of the mounting seat.

[0008] Preferably, the protective coating layer is an epoxy resin layer.

[0009] Preferably, the side wall of the spoke is provided with a lightening hole, and the lightening hole is a strip-shaped hole.

[0010] Preferably, the reinforcement block is a triangular block, and the reinforcement block and the reinforcement rod are both made of aluminum alloy.

[0011] Preferably, the number of the spokes, the number of the reinforcement blocks and the number of the reinforcement rods are all six.

[0012] Compared with the prior art, the utility model provides a high elongation aluminum alloy wheel hub, which has the following beneficial effects:

[0013] 1. The high elongation aluminum alloy wheel hub has a protective coating on the rim surface, the spoke surface and the mounting seat surface. The epoxy resin can form a protective film to prevent oxidation and corrosion, while enhancing the surface hardness and wear resistance of the material, which can not only improve the tensile strength and elongation of the material, but also improve its appearance quality and service life.

[0014] 2. The high elongation aluminum alloy wheel hub has a reinforcing block disposed between the rim and the spokes. The reinforcing block can increase the contact area between the rim and the spokes, thereby improving the supporting strength of the spokes to the rim. The reinforcing rod is used as a supporting structure between the mounting seat and the rim, thereby increasing the structural strength of the wheel hub and improving the elongation of the wheel hub.

[0015] The parts not involved in the device are the same as the prior art or can be implemented by using the prior art. The utility model adopts a protective coating and a reinforcement structure to increase the structural strength of the wheel hub, thereby improving the elongation of the wheel hub.
