The bogie wheel set comprises a wheel axle, key grooves are reserved in the circumferential outer walls of the two ends of the wheel axle, anti-falling ball rings are welded to the positions, close to the key grooves in the two ends, of the circumferential outer walls of the wheel axle, and hubs are connected to the outer walls of the anti-falling ball rings in a sleeving mode; two rolling ball grooves of a circular ring structure are formed in the outer wall of the circumference of the anti-falling ball ring. When the wheel hub is used, the wheel hub and the wheel shaft can rotate relatively, the wheel shaft can rotate in the roller bearing, the rotating efficiency is improved, abrasion is reduced, meanwhile, when the wheel hub needs to be slightly steered, the wheel hub can generate a certain steering amplitude only by pushing the circumferential edge of the wheel hub towards the side face, and therefore the wheel hub is more stable in steering. And then turning is completed.
本发明公开了一种氢能源作业车转向架轮对及转向架,其包括轮轴,所述轮轴的两端圆周外壁处均预留有键槽,且轮轴的圆周外壁靠近两端的键槽处均焊接有防脱球环,所述防脱球环的外壁套接有轮毂,所述防脱球环的圆周外壁开有两个呈圆环形结构的滚球槽。本发明能够在使用的时候,使得轮毂与轮轴可以形成相对转动,并且轮轴也能够在滚子轴承内转动,提高了转动效率减小磨损,同时,需要对轮毂进行微弱的转向的时候,只需向侧面推动轮毂的圆周边缘处即可让轮毂产生一定的转向幅度,进而完成转弯。
