【摘要】 降低冲击载荷,对提高整个传动系的可靠性、减轻重量等意义重大。本文首先研究了传动轴的冲击载荷与传动系各部件参数之间的关系,修正了国外原有的公式,试验证明修正公式的计算精度和适用性都有明显提高。在此基础上,着重计算分析了半轴因杆径尺寸变化导致其扭转刚度变化对其本身和整个传动系冲击载荷的影响,提出了适当降低半轴刚度以减小整个传动系冲击载荷、提高其可靠性的方法。更多还原

【Abstract】 To reduce the impact load and weight,improve product reliability,are important.This paper starts with the load of transmission shaft,to study the relation of dynamic load and structural parameter of every vehicle component on the condition of impact,to amend the original formula.Test proved that the formula amend for calculating the accuracy and applicability have improved markedly.On this basis,the effect of variety of half-shaft dimension to itself,impact load of whole transmission is analyzed,afforded a approach to reduce the impact load of the transmission and a new design idea for half-shaft of transmission.更多还原
