WC5E型铰接式四驱矿用自卸车传动轴的设计

Design of transmission shafts of WC5E articulated mine dump truck with four-wheel driving

针对WC5E型铰接式四驱矿用自卸车的结构特点和传动轴布置形式,通过分析各传动轴的工作状态和运动轨迹,确定了传动轴的长度、伸缩量和断面尺寸等主要性能参数,并根据所传递扭矩和转速对其进行了强度计算和校核,最终设计出满足整车使用要求的传动轴,为此类车辆传动系统的设计提供了方法和依据。

According to the structural features of WC5E articulated mine dump truck with four-wheel driving and the layout of its transmission shafts, after analyzing the operation status and motion track of each transmission shaft, the paper determined the main parameters of the transmission shafts such as the length, shrinkage and cross dimension etc. In addition, the strength calculation and checking of the transmission shafts were conducted according to the transmitted torque and rotary speed. Finally, the transmission shafts meeting the employment requirements of the dump truck were designed, which offered methods and references for design of the transmission system in the truck.
