METHOD AND APPARATUS FOR COOLING AND LUBRICATING AN OFF-AXIS MOTOR/GENERATOR
Application 1452/KOL/2007 published 2008-07-11, filed 2007-10-24
The present invention provides a method for cooling and lubricating an off-axis motor/generator of a hybrid transmission. A transmission case at least partially defines a manifold. A transmission cover is mounted to the transmission case such that the off-axis motor/generator is retained therebetween. The transmission cover at least partially defines an oil passage. Oil is transferred through the manifold and onto a bearing device so that the bearing device is lubricated. Oil is also transferred through the oil passage and onto a torque transfer device such that the torque transfer device is lubricated. A corresponding apparatus for lubricating an off- axis motor/generator of a hybrid transmission is provided is similarly provided. No. of Pages : 14 No. of Claims : 17
