| 20090258747 | Control apparatus for vehicular drive system - A vehicular power transmitting system including a transmission portion constituting a part of a power transmitting path, an electric motor connected to the power transmitting path, an electrically controlled differential portion connected to the electric motor and having a differential state controllable according to a change of an operating speed of the electric motor, a casing accommodating the transmission portion, the electric motor and the electrically controlled differential portion, and a support member for supporting a rotor of the electric motor, the support member including a support portion formed in one axial end portion thereof, at which the rotor is supported rotatably about its axis, and a tapered portion having a diameter increasing in an axial direction from the one axial end portion toward the other axial end portion at which the support member is fixed to the casing, and wherein a winding portion of a stator of the electric motor is disposed in a space formed radially outwardly of the tapered portion, while a fluid passage portion for supplying a working fluid to frictional coupling devices of the transmission portion is disposed in a space formed radially inwardly of the tapered portion. | 10-15-2009 |
| 20110194968 | OIL PUMP - An oil pump having an inner rotor with of external teeth; an outer rotor that is eccentrically provided and has internal teeth that mesh with the inner rotor external teeth, and an oil pump body that accommodates the outer and inner rotors. By rotationally driving the inner rotor to increase and decrease a space between the internal and the external teeth, an intake stroke suctions hydraulic oil from the oil pump body and a discharge stroke discharges the suctioned hydraulic oil to a discharge port formed in the oil pump body. Between the intake and discharge strokes, a confinement stroke cuts off the suctioned hydraulic oil and confines the suctioned hydraulic oil in the space, and a compression stroke reduces the space and compresses the confined hydraulic oil. Further, an interval is set between a finish end portion of the intake port of the oil pump body and a start end portion of the discharge port such that a rotation angle of the inner rotor during the compression stroke is 21 to 27 degrees. | 08-11-2011 |
