自动变速器差速器烧蚀故障分析

Automatic transmission differential ablation failure analysis

文章通过研究自动变速器差速器烧蚀故障的故障机理和故障工况,并通过试验手段在试验室环境下再现了差速器烧蚀故障,根据对差速器故障发生的机理制定了行星齿轮轴、球面垫片、差速器壳体等零部件改善和优化的措施和方向。为差速器的设计优化提供借鉴和参考。

In this article, through the automatic transmission differential ablation failure mechanism and failure mode offailureAnd through tests in laboratory environment recreates the differential ablation failure, According to the mechanismof differential failure made the planet gear shaft, such as spherical gasket, differential shell parts improvement andoptimization measures and direction. To provide reference for the design of the differential optimization.
