| 20120115669 | DIFFERENTIAL APPARATUS - A differential apparatus is provided with a case; a pinion gear; a pair of side gears meshing with the pinion gear; a spherically depressed pinion gear supporting surface portion formed on an inner surface of the case to support a spherically projecting back side portion of the pinion gear; and spherically depressed side gear supporting surface portions formed on the inner surface of the case to respectively support spherically projecting back side portions of the side gears. The projecting back side portions of the side gears which are slidable on the depressed side gear supporting surface portions are formed on tooth portions of the side gears. | 05-10-2012 |
| 20120055753 | HYDRAULIC SYSTEM - A hydraulic system is preferably used in combination with a motor and a clutch of a hybrid vehicle. The hydraulic system is comprised of a pump coupled with the motor to pressurize fluid; a pressurized fluid path coupled with the pump to conduct the pressurized fluid; an operating fluid path connecting the pressurized fluid path with the clutch to actuate the clutch; a depressurized fluid path to conduct depressurized fluid; and an on-off valve operated in cooperation with the clutch to selectively permit fluid connection of the pressurized fluid path to the depressurized fluid path so as to relieve pressure in the pressurized fluid path. | 03-08-2012 |
| 20110105264 | CLUTCH DEVICE - A clutch device is used in combination with a differential device. The clutch device is comprised of: a clutch housed in and rotatable with the differential device and axially movable from a disengaged state into an engaged state; a plunger slidably fit on the differential device and being axially movable from a first position where the plunger does not force the clutch to a second position where the plunger forces the clutch into the engaged state; an anti-rotated solenoid configured to drive the plunger; and a retainer supported by the differential device and in contact with both the plunger at the first position and the solenoid, whereby the plunger is barred from going beyond the first position and the solenoid is axially positioned in place. | 05-05-2011 |
| 20100219036 | DRIVING FORCE TRANSMITTING DEVICE - A driving force transmitting device is comprised of a first rotary member, a second rotary member securely fit around the first rotary member, a third rotary member rotatably supported in the first and second rotary members for being engaged with a shaft, an anti-rotated solenoid slidably fit in a solenoid housing hollow defined by the second rotary member, and a friction clutch driven by the solenoid for transmitting torque between the first rotary member and the third rotary member. | 09-02-2010 |
