The invention discloses an axle end self-locking structure and an axle assembly, the axle end self-locking structure comprises an axle, a hub, an inner bearing, an outer bearing, a first locking nut and a second locking nut; the hub is mounted on the axle through the inner bearing and the outer bearing; the axle is provided with an external thread, the first locking nut and the second locking nut are both in threaded connection with the external thread and jointly form a locking nut assembly, the inner side end face of the locking nut assembly abuts against the outer side end face of the outer bearing inner ring, and the first locking nut is provided with a first matching end face facing the second locking nut; an extension part is arranged on the first locking nut, and an internal thread on the first locking nut extends to the inner surface of the extension part; the second locking nut is provided with a pressing part, and the pressing part is matched with the outer surface of the extending part so as to inwards extrude the extending part when the first locking nut and the second locking nut get close to each other. The axle end structure of the axle becomes simple and is easy to assemble.
本发明公开了一种轴端自锁结构及车轴总成,轴端自锁结构,包括车轴、轮毂、内轴承、外轴承、第一锁紧螺母、第二锁紧螺母;轮毂通过内轴承和外轴承安装在车轴上;车轴上设置外螺纹,第一锁紧螺母和第二锁紧螺母均螺接在外螺纹处且共同组成一个锁紧螺母组件,锁紧螺母组件的内侧端面抵顶在外轴承内圈的外侧端面,第一锁紧螺母上设置有朝向第二锁紧螺母的第一配合端面;第一锁紧螺母上设置有延伸部,第一锁紧螺母上的内螺纹延伸至延伸部的内表面;第二锁紧螺母上设置有一压紧部,压紧部与延伸部的外表面配合以在第一锁紧螺母和第二锁紧螺母相互靠近时将延伸部向内挤压。本发明使车轴的轴端结构变得简单,并易于组装。
