Abstract:
A vehicle drive device for a rotary electric machine. A case of the device includes a support wall portion that extends in a radial direction of the rotary electric machine at a location between the rotary electric machine and the fluid coupling in the axial direction. A first bearing and a second bearing that is separate from the first bearing are disposed at different positions in the radial direction from each other, the first bearing being configured to support the rotor member in the radial direction so as to be rotatable with respect to the support wall portion, and the second bearing being configured to support the coupling input member in the radial direction so as to be rotatable with respect to the support wall portion.
Abstract:
A vehicle drive device in which a friction engagement device, a rotary electric machine, and a speed change device are provided on a power transfer path that connects between an input member drivably coupled to an internal combustion engine and an output member drivably coupled to wheels, the elements provided in this order from the input member side. The disclosed combination achieves a variety of benefits, such as suppressing a steep rise in hydraulic pressure due to pressure discharged from a hydraulic control device, while maintaining a decreased size.

Abstract:
A breather device that communicates an inside of a case with an outside of the case in a vertical direction includes a cylindrical body having a hollow portion that extends in the vertical direction, a stopper inserted in the hollow portion, and a blocking body that is located in a space defined by the stopper in the hollow portion, and blocks a communicating hole provided in a lower part of the cylindrical body as viewed in the vertical direction. The communicating hole ceases to be blocked when the pressure inside the case exceeds a first predetermined value, and the blocking body moves upward in the vertical direction in the space.
Abstract:
A vehicle drive includes a speed change mechanism connected to a rotary electric machine; an output member connected to the speed change mechanism and wheels; an engagement device changes a state of engagement between an input member connected to an engine and the speed change mechanism; a hydraulic pump driven by the engine or the rotary electric machine; a first pressure control device that controls pressure supplied from the pump and supplies the pressure to the speed change mechanism; a second, separate hydraulic pressure control device that controls the pressure supplied from the pump and supplies the pressure to the engagement device; and a case that houses the rotary electric machine, speed change mechanism, engagement device, and pump. At least the engagement device is housed in a space formed by the case, and the second hydraulic pressure control device is provided at a part of the case forming the space.
Abstract:
A fluid transmission device for a vehicle includes a cover and a positioning member. The cover is configured to be driven rotatably about the axis of the fluid transmission device integrally with a drive plate. The drive plate includes a positioning hole that positions the drive plate and the cover. The positioning member is a columnar member. The positioning member is provided on the surface side of the cover, which is opposed to the drive plate, at a radially outer position of the cover. The positioning member protrudes to a drive-plate side in a state where the positioning member is arranged in the positioning hole. The positioning member protrudes from the drive plate obliquely with respect to the axis direction of the fluid transmission device. A radially outermost position of the positioning member is located on the radially inner side relative to a radially outermost position of the cover.
Abstract:
A vehicle driving system includes an engine, an electric motor, a clutch, a torque converter, a transmission, a front module, and a housing. The clutch is configured to selectively connect or interrupt a power transmission path between the engine and the electric motor. The front module includes the clutch and the electric motor. The housing has an accommodation space that accommodates the front module and an accommodation space that accommodates the torque converter. The housing is a single member. The engine, the electric motor, the clutch, the torque converter and the transmission are arranged in series with one another.
Abstract:
A hybrid vehicle includes an engine, a front module, a drive wheel, a transmission, a case, an oil inlet, a return passage, and a bypass passage. The case has a first chamber accommodating the front module, and a second chamber accommodating the transmission. The second chamber includes an oil pan. The oil inlet is arranged inside the oil pan. The return passage communicates the first chamber with the second chamber. The return passage keeps a first oil level inside the first chamber higher than a second oil level inside the oil pan by applying flow resistance to oil. The bypass passage is arranged at a position higher than the first oil level when the hybrid vehicle is in a horizontal position and lower than the first oil level when the hybrid vehicle is leaning forward at a predetermined angle.
