A vehicular transmission includes a gear-change mechanism section that shifts power from a driving source and outputs the power to an output shaft; and a hydraulic system that supplies hydraulic pressure from an oil pump to the gear-change mechanism section via a check valve. The check valve includes a cylindrical valve case in which a passage is formed, a valve stored within the valve case so as to be freely movable in an axial direction of the valve case, a valve seat that is formed at one end portion of the passage in the valve case and that closes the passage when the valve sits thereon, a spring for urging the valve so as to sit on the valve seat, and a spring seat fixed on an axially opposite side of the valve seat in the valve case to support the spring.

A transaxle includes a case having an opening, a second rotating electric machine stored in the opening of the case and having a stator, a rear planetary gear stored in the transaxle case and connected to the second rotating electric machine, a transaxle rear cover sealing the opening and a bolt fixing the second rotating electric machine to the transaxle case. The stator has first and second thrust end faces defining an axial length thereof. The first thrust end face is pressed against an inner surface of the case.

Driving device with rotating electric machine

In setting of an oil temperature increasing process mode, the drive control technique of the invention starts an engine to actuate a mechanical oil pump that pressure feeds a flow of lubricating oil for lubricating the mechanical parts of a transmission and other relevant parts, actuates an electric oil pump that pressure feeds the flow of lubricating oil, and makes a brake Bincluded in the transmission in a semi-engagement state. A motor arranged adjacent to the transmission is then driven with lowered output efficiency. This arrangement effectively accelerates heat generation by the motor and ensures a quick temperature rise of the lubricating oil.

Driving device, motor vehicle equipped with driving device, and control methods of driving device and motor vehicle

The hybrid drive device wherein: a case space is divided by a partition wall into a first case part and a second case part; a drive electric motor is provided in the first case part; a friction engagement element is provided in the second case part; and a through hole that communicates the case spaces is formed.

Hybrid drive device

A vehicle driving apparatus includes a rotating electrical machine; a power transmitting gear mechanism; and a case in which the rotating electrical machine and the gear mechanism are housed in series in an axial direction of the rotating electrical machine, wherein a low rigidity region, which is a region of the case having low rigidity located at an outer periphery of the rotating electrical machine, is covered by a silencer supported on a high rigidity region of the case having a higher rigidity than the low rigidity region.

Driving apparatus for vehicle

A hydraulic control apparatus for a transmission includes a line pressure regulating device that enables control in which an oil pressure from an oil pump is regulated so as to attain a line pressure, and that enables control in which the line pressure is switched stepwise between a low pressure state in a lower pressure range and a high pressure state in a higher pressure range; a plurality of hydraulic servos that engage and disengage friction engaging elements using engagement pressures that are based on the line pressure; and a high pressure state detecting device that detects that the line pressure regulating device is outputting the line pressure in the high pressure state.

Hydraulic control apparatus of transmission

Lubricating oil supply holes are drilled into a first member that is fitted to a plurality of first annular plates by a spline. Of splines to which each lubricating oil supply hole corresponds, lubricating oil grooves provided in the plurality of first annular plates do not overlap the splines on at least one of the front and rear surfaces of the first annular plates, and therefore lubricating oil flowing out of the lubricating oil supply holes is dispersed in a circumferential direction and flows from the inner periphery to the outer periphery of the first annular plates, rather than gathering in each lubricating oil groove and flowing in an outer peripheral direction. As a result, a force generated by an axial lubricating oil flow, which acts in a direction for causing the second annular plates to contact friction materials on the first annular plates, is suppressed, leading to a reduction in drag torque.

Friction engagement device

A hybrid driving unit () is mounted to a vehicle by coupling a coupling section () at the front end of a casing member () with an internal combustion engine () and by mounting a mounting section () at the rear end of the casing member () to a part () of a body (). Still more, a second electric motor (), i.e., a heavy device, is disposed in the rearmost part among a first electric motor (), a power splitting planetary gear (), the second electric motor () and a transmission disposed on an axis () in the casing member (). Thereby, the vibration occurring in the casing member () is suppressed.

Hybrid drive device and automobile mounted with device

Drain holes are arranged in positions offset from valve holes of a valve body. The drain holes have a long chimney-shaped space such that even if insulation material, that has peeled off of an electric motor, is suspended in oil, it is less likely to enter drain chambers through the drain holes.

Hydraulic circuit device and hybrid drive system using that hydraulic circuit device

An output shaft is divided into a first output shaft and a second output shaft. Torque from a motive power distributing planetary gear is transferred to the first output shaft. The first output shaft is supported on partition walls by a both-end support structure via bearings. Assist torque from a transmission is applied to the second output shaft. The second output shaft is also supported on partition walls by a both-end support structure via bearings.

Hybrid drive apparatus

A front end portion of an output shaft is supported by a bearing mounted to an inner peripheral surface of a partition that separates a power distributing planetary gear and a speed change unit. A rear end portion of the output shaft is supported via a bearing which is interposed along a portion of the same plane along which also lies a mounting surface of a bearing in a rear wall that supports a rear end portion of a rotor of a second motor. As a result, the output shaft is supported by a twin support structure via the bearings by the partition and the rear wall.

Hybrid drive system

In response to the driver's gearshift operation from a parking position to a drive position, the control procedure of the invention controls a motor connected to a transmission to output a center adjustment torque Tset, while the transmission is in a state of disconnecting the motor from an axle of a hybrid vehicle. The control procedure adjusts the rotation centers of respective rotational elements in the transmission by rotating the respective rotational elements, and then initiates gradual engagement of a brake to set the transmission in a low gear position. This arrangement desirably retains deviation of the rotation centers of the respective rotational elements in the transmission and prevents potential troubles due to the eccentric rotation centers of the respective rotational elements in the transmission.
