    摘要： The four-wheel drive system for vehicles has a center differential mechanism that divides the rotational driving force from the engine E between the front and rear wheels, and a front wheel side axle differential mechanism that divides this divided rotational driving force between the left and right front wheels. The center differential mechanism is constructed from a single pinion type first planetary gear device which has a first carrier 13 that receives the rotational driving force from the engine E, a first sun gear 11, and a first ring gear 14 that is connected to the rear wheel side, and the axle differential mechanism is constructed from a double pinion type second planetary gear device which has a second ring gear 24 that is connected to the first sun gear 11, a second sun gear 21 that is connected to the right front wheel, and a second carrier 23 that is connected to the left front wheel. The first and second planetary gear devices are disposed adjacent to each other in a coaxial configuration.

    摘要： A power transmission mechanism which is capable of employing one electric motor as a drive source for driving drive wheels and as a drive source for cranking an engine, thereby making it possible to reduce manufacturing costs of the hybrid vehicle, and preventing the motor from offering an extra rotational resistance to the engine when the drive wheels are being driven by the engine, thereby making it possible to enhance fuel economy. In the power transmission mechanism for transmitting the driving force from the engine and/or the electric motor to the drive wheels, when a synchro-clutch for the electric motor, driven by a switching actuator, connects the drive shaft of the electric motor and a driving drive shaft gear to each other, the electric motor is connected to the drive wheels via a meshing gear pair (driving drive shaft gear and driving output shaft gear), whereas when the synchro-clutch connects the drive shaft of the electric motor and a cranking drive shaft gear to each other, the electric motor is connected to the engine via a meshing gear pair (cranking drive shaft gear and cranking input shaft gear), the input shaft of the transmission, and a clutch.

    摘要： A vehicular drive unit comprises a central differential mechanism and a front-wheel side axle differential mechanism. The central differential mechanism comprises a first planetary gear train 10, which includes an output gear body 50, a first carrier 13, which is provided in a one-piece body with this gear body, a first sun gear 11, a first ring gear 14, and a rear-wheel drive gear 15, which is a helical gear formed around this ring gear in a one-piece body. In this drive unit, a differential limiter C is provided between the output gear body 50 (input rotating member) and a drive gear body 55 (output rotating member) to generate a rotational resistance, which acts to reduce the rotational difference between the output gear body 50 and the drive gear body 55.
