Aluminum alloy automobile hub structure

Abstract

The invention relates to an aluminum alloy automobile hub structure. The aluminum alloy automobile hub structure comprises a hub main body, a hub bearing and an anti-slip chain fixing mechanism, wherein the hub bearing is connected into the hub main body; the anti-slip chain fixing mechanism is installed outside the hub main body; the hub main body comprises an inner ring, a spoke, a rim and a hubflange; the hub bearing comprises an oil storage cup, an inner ring, a steel rolling ball and a lubricating ball; and the anti-slip chain fixing mechanism comprises a first fixing ring, a second fixing ring, a connection bolt, a first placement sheet, a second placement sheet, a fixing plate and a clamping plate. The aluminum alloy automobile hub structure is capable of continuously lubricating the bearing in a running process, and adaptive adjustment is carried out on an applying amount of lubricating oil along with the change of a running speed; and in addition, through the arrangement forthe anti-slip chain fixing mechanism which is installed in a detachable manner, installation for an anti-slip chain is facilitated, and the occurrence of the case that the anti-slip chain causes damages to the hub can be effectively avoided.

Description

technical field [0001] The invention relates to the field of automobile parts, in particular to an aluminum alloy automobile hub structure. Background technique [0002] The hub, also known as the rim, is the barrel-shaped, center-mounted part of the tire that is used to support the tire. Common car wheels include steel wheels and aluminum alloy wheels. Steel wheels have high strength and are often used in large trucks; however, steel wheels are heavy and have a single shape, which does not conform to today's low-carbon and fashionable concepts, and is gradually being replaced by aluminum alloy wheels. The existing aluminum alloy wheels have the following problems during use: [0003] (1) When the car needs to drive in the ice and snow environment, in order to ensure the safety of the driving process, it is necessary to wind the anti-skid chain on the tire in advance. Since the material of the anti-skid chain is often harder than the aluminum alloy wheel hub, the wheel hub...

AI Technical Summary

Problems solved by technology

[0003] (1) When the car needs to drive in the ice and snow environment, in order to ensure the safety of the driving process, it is necessary to wind the anti-skid chain on the tire in advance. Since the material of the anti-skid chain is often harder than the aluminum alloy wheel hub, the wheel hub is easy to be damaged. Deformation due to extrusion, destroying the overall beauty

[0004] (2) During the driving process of the car, the pre-added lubricating oil or grease in the hub bearing will be gradually consumed under high-speed friction. If the hub bearing is not lubricated in time, it will be difficult to ensure the safety of the car during subsequent driving. At present, the lubrication of bearings is mostly done manually. It is necessary to disassemble the bearing first, and then apply grease to the bearing parts by hand, which is not only time-consuming and laborious, but also difficult to clean.
