Problems solved by technology

[0006] Ordinary cast aluminum materials have low strength. If a single cast aluminum material is used for molding, more volume of aluminum is needed to meet the requirements of rigidity and strength. The weight reduction ratio generally does not exceed 30%, and it is also subject to various restrictions on space layout. ;In the latest aluminum alloy lightweight technology, the method of inlaying steel sleeves on the aluminum body is used to meet the needs of comprehensive optimization in terms of rigidity and weight, but this method has disadvantages such as complex casting process and high cost

Abstract

The invention discloses a lightweighting high-strength hub for a commercial vehicle, which is made of a high-strength aluminum alloy material, and the whole hub is made of the high-strength aluminum alloy material, so that the weight of the hub can be effectively reduced, and the weight reduction ratio can reach 48 percent; the yield strength of the high-strength aluminum alloy material is 276 MPa, and is between 74% (QT600) and 89% (QT450) of the yield strength of a ductile iron material. Through finite element analysis, the worst rollover working condition is considered, the center of an inner side disc face is arranged to be a variable cross-section circle, so the cross-section material of the hub can be better distributed; on the basis that it is guaranteed that parts have enough strength, the weight of the hub can be the lightest, the axial stress capacity is improved, and the product reliability is guaranteed.

Description

[0001] 【Technical Field】 [0002] The invention belongs to the technical field of wheel hubs for commercial vehicles, and in particular relates to a lightweight and high-strength wheel hub for commercial vehicles. [0003] 【Background technique】 [0004] Vehicles are widely used in road transportation and engineering transportation. The wheel hub is an important link between the ground and the body. Its carrying capacity determines the carrying capacity of the vehicle, and its weight affects the fuel consumption and other economic requirements of the vehicle. On the basis of satisfying the carrying capacity, the lighter the weight, the more advantageous. The current wheel hub products mostly use cast iron alloys or alloy structural steels, such as ductile iron QT450, alloy structural steel 42CrMo and other materials. The forming methods are mainly casting and forging. During the forming process, the melting temperature is high, the energy consumption is high, the cutting is difficult...
