A power transmission apparatusfor a hybrid vehicle having an engineand a motoris provided with a planetary gear mechanismconfigured to differentially rotate a sun gear, a carrier, and a ring gear. The sun gearis connected to one of a first input shaft and a second input shaft and to the motor. The ring gearis connected to a lock mechanism capable of stopping a rotation state. The carrieris configured to transmit power to a counter shaft. The other of the first input shaft and the second input shaft is configured to transmit power to the counter shaftwithout passing through the planetary gear mechanism

A power output apparatustoD including an engine, a motor, and a transmissiontoD having two transmission shafts connected to the engineis provided. The transmission includes a power combination mechanismadapted so as to be able to rotate first to third elements differentially from each other. The first element is connected to any one of the two transmission shafts, the second element is connected to a driving shaftor, and the third element is connected to the motor. The second element combines the power transmitted from the first element and the power transmitted from the third element, and transmits the combined power to the driving shaftand. The other transmission shaft of the two transmission shafts transmits power to the driving shaftorwithout going via the power combination mechanism

Power output apparatus

An automatic transmission for a hybrid vehicle has a first clutch connecting a first drive gear shaft rotatably supporting drive gears Gand G, to an input shaft, a second clutch connecting a second drive gear shaft, rotatably supporting drive gears Gand G, to the input shaft, a first meshing mechanism connecting the drive gears Gand Gto the first drive gear shaft, a second meshing mechanism connecting the drive gears Gand Gto the second drive gear shaft, a brake fixing a third element of a planetary gear mechanism to a transmission case, and a switching mechanism switching to where an electric motor is connected to a first element or where the electric motor MG is connected to the third element. The first element and the first drive gear shaft are connected. A second element and the drive gear Gare connected.

A changing system in a manual transmission is provided. An interlock plate is mounted on a shift-selecting shaft capable of being moved axially in response to a selecting operation and turned about an axis in response to a shifting operation, so that the interlock plate cannot be turned about an axis of the shift-selecting shaft. The interlock plate has a pair of side plate portions which are provided at locations spaced apart from each other in an axial direction of the shift-selecting shaft and through which the shift-selecting shaft extends. A shifting arm disposed between the side plate portions is fixed to the shift-selecting shaft. In such changing system, the shifting arm and an interlock member operatively connected to the shifting arm are interposed between the side plate portions of the interlock plate. Thus, the shifting arm can be used commonly in manual transmissions, in despite of a difference in number of forward speed stages between the manual transmissions, thereby providing a reduction in cost and avoiding an increase in weight due to a variation in number of forward speed stages.

A lubricating oil supply apparatus for a hydraulically operated vehicular transmission has a lubricating oil passage for supplying oil discharged from a discharge port of a pressure control valve which is provided in a hydraulic control circuit of the transmission to lubricating portions thereof as lubricating oil. The lubricating portions are divided into a plurality of groups depending on a change in a required amount of lubricating oil due to a temperature of the transmission. The lubricating oil passage is branched into a plurality of branches corresponding to the groups. The lubricating oil supply apparatus has a choke type of throttle which is disposed in at least one of the branches of the lubricating oil passage.

A pallet with a workpiece mounted thereon is delivered on a pallet carriage, and transferred onto the table of a machine tool which has a different height from the pallet carriage. Lifting mechanisms on the pallet carriage are engaged by respective positioning members in front of the machine tool. The lifting mechanisms are actuated to lift the pallet carriage to position the pallet carriage for transfer of the pallet onto the machine tool table. The pallet is transferred from the pallet carriage onto the machine tool table, half of a predetermined stroke by a first transfer mechanism on the pallet carriage and the remaining half of the stroke by a second transfer mechanism on the machine tool table. The table has vertically movable support rollers for supporting the pallet when it is transferred onto and from the table. When the pallet P is positioned on the table, the vertically movable support rollers are retracted downwardly. When the pallet is transferred onto the machine tool table, clamp units on the machine tool table enter T-shaped slots defined in the lower surface of the pallet, and are actuated to clamp the pallet directly on the table. Since the workpiece on the pallet thus clamped is held in a low position on the machine tool table, the workpiece can be machined by a machining tool that can move freely in a wide space.
