ABSTRACT:
An inventive oil pump system in a power train has a simple oil-delivery arrangement employing a hollow torque-input member containing a member to which oil is to be delivered, a drive shaft extending from the interior of the torque-input member and capable of being rotated by the torque-input member, an oil pump disposed coaxially with the drive shaft, a sleeve fixed to the oil pump and coaxially surrounding the drive shaft, a hollow pump-drive shaft coaxially surrounding the drive shaft, being journalled within the sleeve thus forming an oil-discharge passageway surrounding the drive shaft, and a coupling comprising a non-circular opening in the torque-input member and one end of the pump-drive shaft being inserted into the opening, the end of the pump-drive shaft having a non-circular cross-section capable of engaging the walls of the opening while leaving some radial clearance between part of the walls of the opening and the outer surface of the end of the pump-drive shaft.
