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.
本发明属于轮毂技术领域,具体涉及一种轻量化汽车轮毂,包括轮毂主体,所述轮毂主体的外表面边缘对称安装固定有轮辋,所述轮毂主体的内部安装固定有轮辐,所述轮辐的内部贯通开设有轮轴安装孔,所述轮毂主体的表面开设有固定孔,所述固定孔的内部设置有防磨机构,所述防磨机构包括气门孔、耐磨圈和限位凸起;该发明的固定孔的内表面边缘开设有密封槽并与限位凸起相匹配卡合,有助于增加耐磨圈在固定孔的内部密封性并增加防水效果,且通过限位凸起的限位性能增加耐磨圈在固定孔内部的牢固性避免脱落,且方便耐磨圈安装和拆卸,通过耐磨圈的防磨性能避免气门孔内部安装的轮胎气门管磨损,延长轮胎气门管和轮毂主体的使用寿命。
