The invention discloses an axle wheel set for a heavy-duty truck with 45-ton axle weight. The axle wheel set comprises a hollow shaft, wheels and bearings, wherein the wheels and the bearings are symmetrically arranged at the two ends of the hollow shaft, the bearings are located on the outer sides of the wheels, and the hollow shaft is sleeved with the wheels and the bearings in an interference fit mode. The axle is of a hollow structure, the dead weight of the wheel set can be reduced, the unsprung weight of a bogie can be reduced, abrasion between the wheel and rails can be reduced, ultrasonic flaw detection can be directly conducted on line at regular intervals under the condition that the bogie is not disassembled, the internal defect condition of the axle can be checked, and the safety of the wheel set is ensured. The invention further provides a manufacturing method of the axle wheel set for the heavy-duty truck with 45-ton axle weight.

    本发明公开了一种用于45吨轴重重载货车的车轴轮对,包括空心轴、车轮和轴承,所述车轮和轴承对称设置在空心轴的两端部,轴承位于车轮的外侧,车轮和轴承均过盈配合套接在空心轴上。本发明车轴为空心结构,可以降低轮对自重,减轻转向架的簧下重量,降低车轮和铁轨之间的磨损,还可以在转向架不拆解的情况下直接在线定期进行超声波探伤,检查车轴内部缺陷情况,确保轮对的安全性。本发明还提供了一种用于45吨轴重重载货车的车轴轮对的制造方法。
