Abstract: When neutral control is started by placing a CVT drive clutch in a semi-engaged state while a vehicle is decelerating in a state where a second power transmission path is established, a clutch mechanism that is semi-engaged in neutral control while the vehicle is decelerating is changed from the CVT drive clutch to a forward clutch before a stop of the vehicle, so it is possible to continue the neutral control until a stop of the vehicle. At a stop of the vehicle, a power transmission path is already changed to a first power transmission path that establishes a gear ratio (EL) higher than a highest gear ratio (γmax) that can be established by the second power transmission path. Thus, right after a stop of the vehicle, it is possible to execute idle stop control.

Abstract translation: 当车辆在第二动力传递路径建立的状态下减速时，通过将CVT驱动离合器置于半接合状态而开始空档控制，在车辆正在减速时半离合器接合在空档控制中的离合器机构 在车辆停止之前从CVT驱动离合器变为前进离合器，因此可以继续空档控制直到车辆停止。 在车辆停止时，动力传递路径已经改变为第一动力传递路径，该第一动力传递路径建立比第二动力传递路径能够建立的最高传动比（ymax）更高的传动比（EL）。 因此，在车辆刚刚停止后，可以执行怠速停止控制。

Abstract: A toroidal continuously variable transmission includes an integrated type output side disk (35) which is integrated with one pair of output side disks in a state where back faces of the pair of output side disks are connected to each other, and which is provided with teeth (41) on an outer circumferential surface of the integrated output side disks to serve as an output gear. A tip end surface of the teeth (41) is formed with a protruding portion 42 whic has a width approximately 1/2 of a width of the teeth (41). A reference plane (44) for traction surface processing or the like which is performed on inner surfaces (3a, 3a) of the integrated type output side disk (35) is formed on a tip end portion of the protruding portion (42). Accordingly, when performing processing of forming the reference plane (44) for processing, such as the traction surface processing, on an outer circumferential surface on which the gear teeth of the gear disk in which a gear and a disk are integrated with each other, is formed, it is possible to suppress damage of a cutting edge of a tool for the processing, such as a chip attached to a tool bit of a lathe.

Abstract: A power transmission unit for a vehicle is provided. In the power transmission unit, a continuously variable transmission to alter a speed ratio continuously is disposed between an input shaft to which a torque of a prime mover is inputted and an output shaft rotated by the torque transmitted from the input shaft. A first gear train that transmits the torque to propel the vehicle in the forward direction is arranged parallel to a second gear train that transmits the torque to propelling the vehicle backwardly. The power transmission unit is comprised of: a first clutch device that selectively allows a torque transmitting route from the input shaft to the output shaft via the first gear train to transmit the torque therethrough; a dog clutch that switches the torque transmitting route from the input shaft to the output shaft between a continuously variable speed change route in which the torque is transmitted through the continuously variable transmission and a reverse route in which the torque is transmitted through the second gear train; and a second clutch device that connects and disconnects both of the continuously variable speed change route and the reverse route to/from at least any one of the input shaft and the output shaft.
