Abstract—

Root cause analysis is carried out to explain the break in a torsion shaft installed in an internal combustion engine (ICE) and inside the overdrive gearbox at the inlet of the transmission torque converter and inside the turning mechanism in a lightweight caterpillar vehicle having a high specific power (more than 30 hp/tf). It is proposed to install a spring-friction torsional vibration damper on the torsion shaft. This shaft can operate in oil inside a confined volume at the outlet flange of the internal combustion engine to cope with high cyclicity in the torsion shaft operations, to respond to potential torsional shock, and to reduce the level of torsion shaft vibrations. The research results can be used to design hydromechanical transmission in lightweight caterpillar vehicles having a high unit power rating.

分析安装在 ICE 中的扭力轴和位于变速箱变矩器入口处的超速齿轮箱中的操作，以及安装在轻型 Caterpillar 机器中以提高可靠性的转向机构

摘要-

进行根本原因分析以解释安装在内燃机 (ICE) 和超速档变速箱内部的扭力轴在变速箱变矩器入口处和具有高比值的轻型履带式车辆转向机构内部的断裂。功率（超过 30 hp/tf）。建议在扭力轴上安装一个弹簧摩擦扭振减振器。该轴可以在内燃机出口法兰处有限容积内的油中运行，以应对扭力轴操作中的高循环，响应潜在的扭转冲击，并降低扭力轴振动水平。研究结果可用于设计具有高单位额定功率的轻型履带式车辆的液压机械传动装置。
