Engagement noise isolator for an automatic transmission

摘要

An assembly including mutually engaged spline teeth includes a rubber isolator, retained in position between an external splined surface, and an internal splined surface is supported against movement and is adapted to contact the lateral face of an adjacent spline tooth so that the isolator is compressed due to rotation of one of the components relative to the other over a range of movement. Then the metal surfaces of the teeth on the first and second components are in mutually contact. In one form, the isolator is retained by an interference fit on a post located within an intervening space between teeth.
