Embodiment 1

[0042] Such as figure 1 As shown, the appearance structure of the automobile wheel hub (HUB) of the present invention is exactly the same as the macroscopic structure of the automobile wheel hub (HUB) in the prior art. Such as figure 1 As shown, its main body is a sleeve-shaped structure, and the central round hole is used to connect with the automobile half shaft. The main structure is in the shape of a "T", and the small end thereof is provided with a screw hole as a small flange 1, which is used for threaded connection with the dust cover during installation. The big end is provided with a screw hole, which is used as a big flange 6 to be connected with a wheel and a brake hub during installation. The main body sleeve 2 is used for torque transmission and support, and keeps the overall structure stable.

[0043] On the periphery of the main body sleeve 2, close to the inside of one end of the large flange 6, a plurality of connecting blocks 4 are arranged in the coaxial ...

Embodiment 2

[0060] Embodiment 2: as figure 1 The wheel hub with the structure shown in this embodiment is basically the same as that of Embodiment 1, the difference is that the connecting block 4 is not formed by spinning after forging, but is formed by milling, cutting and finishing after forging, but the connection The clamping block 4 has structural features formed by forging. The specific production process is as follows: image 3 Semi-finished shape shown. An annular platform 41 is formed in the semi-finished product, and then the annular platform 41 is milled to form the structure of the annular groove 3 . The cutting operation is performed again to form the notch 5 , and then the connecting block 4 is formed. Although the product of this method and structure cannot reach the mechanical strength of the spinning part of Example 1, it basically meets the characteristics and mechanical strength of the forging structure, which is higher than that of the product formed by casting.

...

Embodiment 3

[0062] Embodiment 3: The structure of the forged automobile hub (HUB) of this embodiment is as follows figure 2 As shown, the structure is basically the same as that of Embodiment 1, the difference is that there is no annular groove 3 between the connecting block 4 and the outer wall 2 of the main body sleeve, which is a solid connection state, which is formed during the forging process. formed in one. Products with this structure can also achieve the mechanical properties of forged products, but the weight of the product is slightly increased, and the weight of the finished product is 14.5 kg. The product of this embodiment is also formed through material selection and three-step forging.

Abstract

The invention discloses an automobile hub (HUB) and a manufacturing method. The automobile hub is of a sleeve type structure. Connecting flanges are arranged at the two ends of a main body sleeve respectively, and an annular platform is arranged on the outer side of the sleeve wall of the main body sleeve. A plurality of connecting clamping blocks extending in the axial direction are arranged on the annular platform, and the connecting clamping blocks are annularly and evenly distributed. At least the sleeve, the connecting flanges and the annular platform are of forging structures, and the connecting clamping blocks can be of a structure of spinning after forging. The manufacturing method of the automobile hub (HUB) comprises the steps of forging and pressing, spinning, heat treatment, cutting, finish machining and surface treatment. Although the macrostructure of the product is the same as that of a product in the prior art, the microstructure of the product is different due to the fact that the manufacturing method is different. By using the method, the microstructure of the product can be changed, and the product performance is improved.

Description

technical field [0001] The invention relates to an automobile wheel component, in particular to an automobile hub (HUB), and also relates to a manufacturing method of the automobile hub (HUB). Background technique [0002] Automobile hub (HUB) is an important component assembled with automobile wheels and bearings. It is installed between the wheels and bearings and forms a rolling combination with the half shaft. It directly plays the role of connecting the wheels and the body and carries torque. . [0003] The automobile hub (HUB) should meet the following conditions: first, the strength is sufficient; second, the weight should be reduced as much as possible. At present, the automobile wheel hub (HUB) in the prior art is still all cast. In China, nodular cast iron is generally used for casting, and some foreign countries are cast with cast aluminum. Various materials such as copper and steel can be used, but they have not been separated from the use of casting. Ideas for...
