Abstract

Constant Velocity Joint (CVJ) mechanisms enable torque transmission between two shafts at a fixed or variable angle. Cross groove CVJs are typically used in high performance automotive applications due to their versatility and light weight. Critical failure modes, such as pitting or abrasive wear, occur due to the harsh tribological conditions at ball reversals. In this research, an existing mathematical model is developed further for the case of cross groove CVJs including an accurate contact mechanics model. The developed model is validated against a published data set from literature. Surface topography of worn raceways are experimentally measured and the results from the developed model are corroborated with the measured surface parameters. This improved model shows the correlations between predicted contact force variation and wear scar depths during ball reversals, hitherto not reported in the literature.

高性能赛车条件下设计的十字槽等速关节机构分析

恒速关节(CVJ)机构使扭矩在两个轴之间以固定或可变角度传递。由于其通用性和重量轻，交叉槽cvj通常用于高性能汽车应用。关键的失效模式，如点蚀或磨料磨损，发生在恶劣的摩擦条件下的球反转。在本研究中，进一步发展了现有的交叉槽cvj的数学模型，包括精确的接触力学模型。开发的模型通过文献中已发布的数据集进行验证。实验测量了磨损滚道的表面形貌，所建立的模型的结果与实测的表面参数相吻合。这个改进的模型显示了预测的接触力变化和球反转期间磨损疤痕深度之间的相关性，迄今为止尚未在文献中报道。
