Abstract
The present invention provides a hybrid transmission with two motor/generators, one being 'on-axis' and sharing an axis of rotation with an input and output shaft of the transmission, and another being 'off-axis' with a distinct axis of rotation from that of the first motor/generator. The transmission is adapted for cooling and lubricating the off-axis motor/generator, and includes a case at least partially defining a manifold. A transmission cover is mounted to the case such that the off-axis motor/generator is retained therebetween. The transmission cover at least partially defines an oil passage. The manifold is adapted to transfer oil 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.
