Provided is a compound motor (14) comprising a magnet rotor (19) supported by bearings (B3, B4) in a rotatable manner, a winding rotor (20) supported by bearings (B5, B6) in a rotatable manner relative to the magnet rotor (19) at the inner side of the magnet rotor (19) and having rotor winding units (20b), and slip ring mechanisms (25). A space is formed in the inner circumference of the winding rotor (20). At least a part of the slip ring mechanisms (25) is arranged in the space of the inner circumference of the winding rotor (20). The bearings (B3 to B6) include bearings (B3, B6), the internal diameter of each is larger than the size of slip ring mechanisms (25) with respect to the radial direction. The bearings (B3, B6) are arranged outside the slip ring mechanisms (25) with respect to the radial direction.

During an inertial energy storage operation, electric power conversion at an inverter is controlled such that a direct current electric power from an electric power storage device is converted into an alternating current by the inverter so as to be supplied to stator windings, such that torque in the direction of engine rotation is applied to an output side rotor from a stator to rotatively drive the output side rotor in a state where power transmission from the output side rotor to a drive axle is stopped. During a cranking operation after the inertial energy storage operation, the electric power conversion at an inverter is controlled to permit application of the alternating current to rotor windings, such that a torque in the direction of engine rotation is applied to an input side rotor from the output side rotor, thereby rotatively driving an input side rotor to crank the engine.

A continuously variable transmission includes a continuously variable transmission mechanism that includes an input disk, an output disk, and planetary balls sandwiched between them and that steplessly changes a transmission ratio between the input disk and the output disk by tilting the planetary balls, wherein cooling performance of a cooling device for the continuously variable transmission mechanism is enhanced as the transmission ratio becomes larger than 1 or smaller than 1.
摘要:
By pouring, by means of pressure, melted liquid of magnesium or magnesium alloy into a hollow portion which is formed using a casting mold, a valve body where a channel groove for hydraulic oil for use in a speed change operation of the automatic transmission is formed. In the above, the channel grove for the hydraulic oil is formed due to a convex portion which is formed on the mold so as to project into the hollow portion. As the magnesium has small heat capacity, variation of the temperature of the mold during the cooling and heating cycle can be suppressed. Moreover, as the magnesium melted liquid has no reactivity with respect to the casting mold, the convex portion is not deteriorated. This allows employment of a mold having a thinner convex portion formed thereon, and therefore formation of a valve body having a narrower channel groove.
