Lightweight automobile hub

Abstract

The invention belongs to the technical field of hubs, in particular to a lightweight automobile hub. The lightweight automobile hub comprises a hub main body; rims are symmetrically and fixedly installed on the edge of the outer surface of the hub main body; a spoke is fixedly installed in the hub main body; a wheel shaft installation hole is formed in the spoke in a penetrating mode; a fixing hole is formed in the surface of the hub main body; an anti-abrasion mechanism is arranged in the fixing hole; and the anti-abrasion mechanism comprises an air valve hole, an anti-abrasion ring and a limiting protrusion. A sealing groove is formed in the edge of the inner surface of a fixing hole and matched and clamped with a limiting protrusion. The sealing performance of the anti-abrasion ring inthe fixing hole is improved, and the waterproof effect is improved; the firmness of the anti-abrasion ring in the fixing hole is improved through the limiting performance of the limiting protrusions,falling off is avoided, the anti-abrasion ring is convenient to mount and dismount, the tire valve pipe mounted in the air valve hole is prevented from being abraded through the anti-abrasion performance of the anti-abrasion ring, and the service life of the tire valve pipe and the service life of the hub main body are prolonged.

Description

technical field [0001] The invention belongs to the technical field of wheel hubs, and in particular relates to a lightweight automobile wheel hub. Background technique [0002] The wheel hub is an important part of the car. The car tire itself is soft, and the inner profile of the tire supports the barrel-shaped structure of the tire. With the comprehensive implementation of energy saving and emission reduction, and the reason of price competition, the car is becoming more and more lightweight. The research and development towards lightweight is firstly the use of materials, such as carbonaceous materials and the use of a large number of aluminum profiles, and then the lightweight research and development of the overall structure. For example, in order to reduce weight while ensuring strength, the wheel hub uses integrated die-casting molding technology. [0003] When the existing automobile hub is in use, the outer surface of the valve tube and the valve hole are easily wo...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a light-weight automobile wheel hub to solve the problem that the valve tube and the valve hole of the tire are easily worn due to the high-speed rotation of the hub or the easy wear of the tire valve hole when the wheel hub is in use. The outer surface and valve hole are easy to wear, which reduces the service life of the valve tube and hub and increases the maintenance cost
