Patent ID: 7247112

Claim:
An apparatus for cooling and lubricating a hybrid transmission comprising: a fluid reservoir; a first rotating shaft defining a flow passage therein, said first rotating shaft further defining a first plurality of orifices; a second rotating shaft defining a second plurality of orifices, the first and second rotating shafts defining a clearance cavity therebetween, said clearance cavity being in fluid communication with said first and second plurality of orifices; a planet gear assembly having a planet carrier; a first plurality of bushings positioned external to said clearance cavity and adapted to seal the flow passage of the first rotating shaft, said first plurality of bushings being configured to leak a predetermined amount of fluid to cool and lubricate the bushings; and a pump adapted to transfer fluid from the reservoir, into the flow passage of the first rotating shaft, through said first plurality of orifices, into said clearance cavity, through said second plurality of orifices and onto the planet carrier such that the planet carrier is cooled and lubricated.
