Abstract

A baffle for a transmission of a vehicle is provided. The transmission includes a gearbox that outputs torque to a differential, which distributes the torque to the wheels. A chain transfers the torque from the transmission to the differential. A baffle is provided adjacent to, but spaced from, the chain to contain and direct at least some of the lubricating fluid that the chain comes in contact with. The baffle has a base with a planar side surface. A flange extends from the base, and extends radially about part of the transmission output and the differential input to follow the path of the chain. One end of the flange is provided with an opening to direct fluid through the opening, out of the baffle and into other regions of the transmission such as the transmission sump. This inhibits buildup of fluid in the sump of the baffle.
