Embodiment Construction

[0012] see figure 1 , 2 , 3, the present invention has hub body 1, has four installation holes 3 on the installation hub 2 of hub body 1 (can also be 5, 6 or even more installation holes according to different specifications), especially: in A steel sleeve 7 is housed in each mounting hole 3, and a bolt hole is arranged in the steel sleeve 7. The bolt hole is composed of a cylindrical hole section 4 and a tapered hole section 6, and anti-skid rollers are rolled on the surface of the tapered hole of the bolt hole. spend 5.

[0013] The anti-slip knurling 5 on the surface of the tapered hole of the bolt hole of the steel sleeve described in this embodiment is a textured knurling, and the knurling modulus is 0.8.

Abstract

The invention relates to a technology for improving automobile parts, and discloses a reinforced aluminum alloy hub with antiskid bolt holes. The reinforced aluminum alloy hub is provided with a hub body, wherein at least four mounting holes are formed in a mounting hub of the hub body. The reinforced aluminum alloy hub is characterized in that a steel sleeve is arranged in each mounting hole, wherein a bolt hole is formed in each steel sleeve, and consists of two sections, i.e. a cylindrical hole and a taper hole; antiskid knurls are formed on the surfaces of the taper holes of the bolt holes in a rolling way. According to the reinforced aluminum alloy hub, the problems of potential safety hazards in driving due to the facts of bolt hole damage and loosening probably caused by insufficient strength and poor antiskid performance of the bolt holes in a conventional aluminum alloy hub are solved; the invention is applied to the improvement of various types of aluminum alloy hubs.

Description

technical field [0001] The invention relates to the improvement technology of auto parts, in particular to an aluminum alloy wheel hub with reinforced antiskid bolt holes. Background technique [0002] The wheel hub is one of the main moving parts of the car. It is fastened to the drive shaft by bolts. Therefore, there are generally at least four bolt holes on the mounting hub of the wheel hub. Usually, the bolt holes are composed of two sections: a cylindrical hole and a tapered hole. , The cap head of the bolt is usually pressed into the tapered hole with a tapered surface. In the prior art, the inner walls of the bolt holes on the hub are all smooth, and do not have anti-skid reinforcement and functions; because the hub and the bolts work for a long time under high-speed and harsh environments, and bear a large torque, the bolts If the fastening is not firm, it may break and loosen after long-term work. On the other hand, the strength of the aluminum alloy bolt holes is ...
