An output side transfer memberof a second clutch C-extends around the outer circumferences of the output side transfer membersof the third and first clutches C-, C-, the output side transfer member(or) of a fourth clutch C-and the output side transfer memberof a third clutch C-are linked to a sun gear S, the output side transfer member(or) of a fourth clutch C-, an output side transfer memberof a third clutch C-, and a sun gear S, which rotate integrally, are disposed radially inward with respect to the output side transfer memberof the first clutch C-. Thereby, it becomes possible to reduce the diameter of the output side transfer member(or) of the fourth clutch C-, to reduce the weight and inertia, and to improve the controllability of the automatic transmission

Automatic transmission for a vehicle

A vehicle parking control system includes a shift-by-wire apparatus that is operated based on an electric range position signal corresponding to one of the driving range and the non-driving range of the drive unit and that switches the lock mechanism to an engaged state and a released state in conjunction with a switching of one of the driving range and the non-driving range of the drive unit; a vehicle parking brake unit that is operated based on the range position signal and that switches a brake unit, which is provided to stop a rotation of the rotating member of the vehicle, between a braking state and a released state; and a control unit that operates the shift-by-wire apparatus and the vehicle parking brake unit based on the range position signal.

Vehicle parking control system

An automatic transmission that includes a case; and a range shift device that includes: a housing with an opening portion on one side, a motor that produces a driving force based on a signal from a manually operated shift operating device, and a mechanical transmission that transmits the driving force of the motor to a manual valve, wherein the range shift device shifts a running range in accordance with a shift position of the manual valve, and the case has a joining portion that closes the opening portion of the housing.

Automatic transmission and running range switching device

A hydraulic power transmission device includes a toroid portion, a turbine hub, and a lock-up device. The toroid portion includes a pump impeller and a turbine runner. The turbine hub is engaged with an input shaft of a transmission and holds the turbine runner. The lock-up device is installed so that it engages and disengages freely and it mechanically transmits to the turbine hub rotation that is transmitted from a drive power source. The toroid portion and the lock-up device overlap in the axial direction. Because the toroid portion and the lock-up device overlap in the axial direction, the size of the hydraulic power transmission device in the axial direction can be reduced, and the hydraulic power transmission device can be made more compact.

Hydraulic power transmission 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

A vehicle automatic transmission includes a planetary gear that reduces a speed of an input rotation of an input shaft and outputs a reduced speed rotation; at least two clutches that are capable of transmitting the reduced speed rotation that passes through the planetary gear; a planetary gear set having at least two rotation elements, wherein each rotation element can transmit the reduced speed rotation transmitted by the clutches; and an input transmitting clutch that is capable of transmitting the input rotation into one of the at least two rotation elements.

Automatic transmission for vehicle

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 hydraulic control apparatus for a multi-stage automatic transmission includes solenoid valves such as the linear solenoid valves that are formed as normally closed valves. A first clutch apply relay valves that outputs a forward range pressure as a reverse input pressure during an all-solenoid-off mode, and a second clutch apply relay valve that switches between a left half position that inputs a reverse input pressure to a discharge port and a right half position that inputs the reverse pressure to the discharge port are provided. The second clutch apply relay valve is set to the right half position during normal engine startup and locked based on the lock pressure by feeding the line pressure as a lock pressure and is set at the left half position that interrupts the lock pressure after the engine is restarted during all-solenoids-off.

Hydraulic control apparatus for a multi-stage automatic transmission

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

A hydraulic control apparatus for an automatic transmission comprises a linear solenoid valve for outputting a control pressure, a primary regulator valve for regulating a line pressure in accordance with the control pressure, and a secondary regulator valve for regulating a secondary pressure in accordance with the control pressure, the secondary pressure being supplied to a lock-up clutch and a torque converter. A spool of the secondary regulator valve is formed to comprise a large diameter portion and a small diameter portion, thereby eliminating the need for components such as a sleeve, and the line pressure can be input into an oil chamber formed between the large diameter portion and small diameter portion.

Hydraulic control apparatus for automatic transmission

A vehicular drive apparatus includes a case, a first brake having a first friction plate set and a second brake having a second friction plate set wherein the first friction plate set and the second friction plate set are sequentially arranged on a single axis, and a first hydraulic servo arranged to correspond to the first brake and a second hydraulic servo arranged to correspond to the second brake.

Vehicular drive apparatus

A vehicular automatic transmission is provided with a reduction planetary gear for reducing and outputting an inputted rotation of an input shaft, first and third clutches for enabling the transmission of a reduced rotation reduced through the reduction planetary gear, a planetary gear unit having second and third sun gears to which the reduced rotation is transmitted by the first and third clutches and a fourth clutch for enabling the transmission of the inputted rotation to the second sun gear. The fourth clutch is linked to the second sun gear of the planetary gear unit via output side members, i.e., a clutch drum and a link member, of the third clutch to commonly use as the output side members. Thereby, the automatic transmission may be compactly built.

Vehicular automatic transmission

A planetary gear lubrication unit includes a planetary gear unit having a sun gear and a carrier that has a plurality of pinion shafts, wherein each of the plurality of pinion shafts rotatably supports a pinion, a plurality of side plates that support the plurality of pinion shafts, and a rotating shaft arranged in a center portion of the planetary gear unit, in which lubrication oil supplied from the rotating shaft is led to a portion of the pinion shafts that support the pinions.
