Problems solved by technology

Although the strength of carbon fiber material is more than 8 times that of aluminum alloy material, its wear resistance is worse than that of aluminum alloy material; and because the screw is in direct contact with the carbon fiber during installation, it is easy to generate a potential difference under acidic liquid conditions, corrode the screw, and last for a long time. There are security risks

Embodiment 1

[0013] Such as figure 1 , figure 2 As shown, the center plate mounting surface structure of a carbon fiber hub described in this embodiment includes a hub body 1. The hub body 1 includes a rim 2, a spoke 3, and a center plate 4. The center of the hub body 1 is the center plate 4. A central hole 5 is provided in the center of the middle plate 4, and a PCD hole 6 is provided on the middle plate 4 on the periphery of the central hole 5. One of the axial sides of the middle plate 4 is a mounting surface, and an aluminum alloy is attached to the mounting surface Disk surface 7, the aluminum alloy disk surface 7 is provided with a first hole 8 corresponding to the center hole 5 of the middle disk 4, and the aluminum alloy disk surface 7 on the periphery of the first hole 8 is provided with a PCD hole 6 corresponding to the middle disk 4 No. 2 hole 9, and the No. 1 hole 8 on the side of the aluminum alloy disc surface 7 that is attached to the middle plate 4 is formed with an annular...

Abstract

The invention relates to the technical field of composite material automobile hub preparation, in particular to a center plate mounting surface structure of a carbon fiber hub. The structure comprisesa hub body, a center plate is arranged in the center of the hub body, a center hole is formed in the center of the center plate, PCD holes are formed in the center plate on the periphery of the center hole, one axial side surface of the center plate is a mounting surface, an aluminum alloy plate surface is arranged on the mounting surface in an attached mode, a first hole corresponding to the center hole of the center plate is formed in the aluminum alloy plate surface, a second hole corresponding to the PCD holes of the center plate is formed in the position, on the periphery of the first hole, of the aluminum alloy plate surface, and a horn-shaped lantern ring is arranged in each PCD hole. According to the center plate mounting surface structure of the carbon fiber hub, abrasion of a carbon fiber material caused by direct contact between the carbon fiber hub and an assembled bolt can be effectively avoided, in addition, direct contact between the carbon fiber material and an aluminum alloy material can be blocked, and the situation that aluminum alloy is corroded in an acid solution, and safety is affected is avoided.

Description

Technical field [0001] The invention relates to the technical field of preparing composite material automobile hubs, in particular to a center plate mounting surface structure of a carbon fiber hub. Background technique [0002] Existing automobile wheels, regardless of the casting or forging process, and whether the rim and the center plate are one-piece or two-piece, are made of aluminum alloy, and the screws will not damage the PCD hole during assembly; but with the trend of lightweight cars, Carbon fiber materials have been widely used in auto parts. As the most important wheel hub of automobiles, carbon fiber and other composite materials have been used as the main materials in foreign and domestic production, and have passed the tests of major test standards for automobile wheels. Although the strength of carbon fiber material is more than 8 times that of aluminum alloy material, its wear resistance is worse than that of aluminum alloy material; and because the screw is in ...
