Abstract: A stepless transmission 1 is provided for preventing drive wheels from being driven despite the driver's intention during vehicle deceleration. A control device 40: when the required drive force of the vehicle is 0, controls the output rotational speed Ne of a travel drive source 50 to be Ne2, and controls the transmission gear ratio i of the transmission 1 so that the transmission 1 in the case where the Ne is Ne1 changes from a first state to a second state; and when the vehicle speed V is less than a boundary speed Vgn, controls the ratio i to be a state maintaining transmission gear ratio ign that enables the first state to be maintained even during vehicle deceleration. In the second state a rotational drive force is transmitted from an input shaft 2 to an output shaft 3. In the first state the transmission is prevented.

Abstract: A vehicle power transmission device equipped with a crank type transmission unit is provided in which since a first sprocket provided on an input shaft upstream portion and a second sprocket provided on an output shaft downstream portion are connected by an endless chain, and a dog clutch is disposed between the input shaft main body portion and the input shaft upstream portion, when the input shaft main body portion is seized and becomes non-rotatable, the dog clutch is disengaged so as to detach the input shaft upstream portion from the input shaft main body portion, and the driving force of an engine is transmitted to the output shaft downstream portion via the input shaft upstream portion, the first sprocket, the endless chain and the second sprocket, thereby enabling the vehicle to travel in the minimum necessary way.

Abstract: A vehicular power transmission device including a crank type continuously variable transmission is provided in which when the vehicle transitions to the deceleration traveling state, a second one-way clutch (69) is engaged to thus transmit to an engine (E) the driving force that has been transmitted back via auxiliary driving force transmission method (54), thereby enabling engine braking to be operated.

Abstract: A vehicular power transmission including a crank type continuously variable transmission is provided in which when the rotational speed of an engine during deceleration fuel cut-off is at least a first rotational speed, which is an upper limit of rotational speed at which plunging of a starter motor is possible, but less than a second rotational speed, which is a lower limit of rotational speed at which self-ignition of the engine is possible. The engine is cranked and restarted by transmitting the driving force of an electric motor of a shift actuator to an input shaft via first and second engagement portions. This eliminates the need for restarting the engine with the starter motor by waiting until the rotational speed of the engine has become less than the first rotational speed, thus reducing the time required for restarting the engine. Moreover, the electric motor can be made small.

Abstract: An output shaft is formed from an output shaft main body portion connected to a transmission unit. An output shaft downstream portion arranged further on the downstream side in the power transmission direction than the output shaft main body portion. A dog clutch is disposed between the output shaft main body portion and the output shaft downstream portion. When the output shaft main body portion is seized and cannot rotate, it is possible, by disengaging the dog clutch to detach the output shaft downstream portion from the output shaft main body portion, to prevent a driven wheel from being locked by the seized output shaft main body portion.

The drive system includes an engine, a first shaft connected to a crankshaft, a second shaft, a first clutch, a motor generator, a third shaft, a first transmission, a one-way clutch, and an ECU for controlling a gear ratio of the first transmission and the first clutch. The first transmission includes a rotating ring, a rocking portion, and a rotation radius variation mechanism. If an angular velocity of the rocking portion is higher than or equal to a rotational speed of the third shaft, the one-way clutch transmits a power in only one direction of the rocking portion to the third shaft.
