某自动变速器油底壳漏油分析与优化

Analysis and Optimization of Oil Spill of an Automatic Transmission Oil Pan

油底壳作为自动变速器上非常重要的零部件,与变速器壳体之间的密封设计尤为关键。油底壳和变速器壳体结合面之间漏油是各汽车生产厂家面对的疑难问题,变速器油底壳漏油问题是由综合性因素导致,必须进行系统性分析才能找到根本原因。文章通过某车型自动变速器油底壳漏油问题进行分析研究,并对装配过程进行优化和改进,最终解决由于油底壳安装螺栓扭矩衰减导致的漏油问题。

As a very important part of automatic transmission,the seal design between oil pan and transmission shell is particularly critical.Oil leakage between the oil pan and the joint surface of the gearbox shell is a difficult problem faced by various automobile manufacturers.The oil leakage problem of the gearbox oil pan is caused by comprehensive factors,and it must be systematically analyzed to find the root cause.In this paper,the oil leakage problem of the oil pan of a vehicle's gearbox is comprehensively analyzed,and the assembly process is optimized and improved.Finally,the oil leakage problem caused by the torque attenuation of the oil pan installation bolt is solved.
