摘要

某重型载货汽车转向系统中的球头销易发生断裂损坏。查看损坏情况后,分析可能存在运动干涉问题,考虑到转向系的空间运动比较复杂,采用空间坐标变换的方法,建立整体坐标系和所需的局部坐标系,通过转换矩阵建立坐标系之间的关系,将局部坐标系的空间运动转换到整体坐标系中。求解出在车轮转向范围内球头销的摆角,查看其是否超出球头销设计摆角范围。最终由分析得出球头销确实存在运动干涉问题,为其结构设计改进提供一定的依据。

Abstract

The ball pin of the steering assembly fractured during using for a special type heavy-duty truck.After inspection,the motion interference problem may exist.Considering the complexity of the space motion of steering system,the global coordinate system and several local coordinate systems and the relationship between them through the transformation matrix are established.The swing angle of the ball head pin is solved to check whether it is beyond the range of design angle.Eventually,find out the the movement interference problems is exist in the ball head pin.A basic theory for its structural improvement of the vehicle is provided.
