Segmented clutch plate for automatic transmission

摘要

The cooling performance of a wet disc clutch pack (10') is improved by using a segmented steel reaction plate (180). The segmented configuration of the reaction plate forms a triangular shaped groove (201) with an unsegmented reaction plate. The groove channels cooling lubricant in a manner to increase the convective heat transfer area for the flow of cooling lubricant, whereby to improve the cooling of the clutch pack.
