Abstract

The invention discloses an automobile wheel hub which is made of a modified alloy. The constitution of alloy is improved to effectively enhance the toughness and greatly reduce the phenomenon of rupture. Compared with the existing product, the rupture rate is lowered by 40-50%, and the automobile wheel hub has favorable market prospects.

Description

[0001] technical field [0002] The invention relates to a wheel hub for automobiles. Background technique [0003] The wheel hub, also known as the rim, the wheel, and the tire bell, is a barrel-shaped, center-mounted metal part on the shaft that supports the tire on the inner contour of the tire. There are many types of hubs according to diameter, width, molding method and material. However, most of the existing commercially available products have poor toughness and are easy to break. Contents of the invention [0004] The object of the present invention is to provide a wheel hub for automobiles aiming at the above-mentioned defects in the prior art. [0005] In order to achieve the above purpose, the technical solution provided by the present invention is: a wheel hub for automobiles, the material is alloy, and the alloy composition is calculated in parts by weight: 25-35 parts of tungsten carbide, 25-35 parts of titanium carbide, 25 parts of tantalum carbide -35 pa...
