The invention provides a steering axle hub bearing of a new energy automobile, and relates to the technical field of automobile accessories, the steering axle hub bearing comprises a hub bearing sleeve, the hub bearing sleeve is of a cylindrical through cavity structure, and two bearing bodies are arranged in a cavity of the hub bearing sleeve; a steering knuckle sleeve is arranged between the two bearing bodies, due to the fact that the supporting baffle ring can slide along the limiting sliding groove, the two bearing bodies can be stably supported through the elastic effect of the buffer spring, the bearing bodies can be kept balanced through the elastic effect, and the two bearing bodies can rotate stably relative to each other; according to the steering axle hub bearing, the balance of pressure applied to two bearing main bodies by a steering knuckle is improved, so that the overall structure of the hub bearing is more stable, and the problems that when an existing steering axle hub bearing of the new energy automobile is used, two bearings are generally arranged in a hub bearing sleeve for matched use, the pressure applied to the two bearings by the steering knuckle has a certain difference, and the hub bearing cannot be damaged are solved. And the stability of the overall structure of the hub bearing is influenced.

    本发明提供一种新能源汽车的转向桥轮毂轴承,涉及汽车配件技术领域,包括:轮毂轴承套,所述轮毂轴承套为柱形通腔结构,且轮毂轴承套的空腔内设有两处轴承主体;两处所述轴承主体之间设有转向节套管,由于支撑挡环能够沿着限位滑槽滑动,能够利用缓冲弹簧的弹性作用对两处轴承主体进行稳定支撑,有利于通过弹性作用使轴承主体保持平衡,使两处轴承主体相对旋转平稳,提高了转向节对两处轴承主体施加压力的均衡性,从而保证本轮毂轴承整体结构更加稳定,解决了现有的新能源汽车的转向桥轮毂轴承在使用时,通常轮毂轴承套内设有两处轴承配合使用,而转向节对两处轴承施加的压力有一定的差异,影响轮毂轴承整体结构的稳定性的问题。
