Abstract
An electric beam axle for use in an electric or hybrid motor vehicle includes a valve positioned between a differential case and an axle tube. The valve includes a valve housing with a fluid flow path extending through the valve housing, and a valve member positioned within the fluid flow path of the valve housing. The valve can also include a stop coupled to the valve housing, the stop being configured to retain the valve member within the fluid flow path of the valve housing. The valve member is configured to prevent fluid from flowing through the fluid flow path and into the axle tube of the electric beam axle when the electric or hybrid motor vehicle is driving across steep road grades and/or under lateral acceleration (cornering) events.
