Abstract:
1. A power transmitting apparatus for selectively transmitting power from a driving source of a vehicle to wheels of the vehicle, comprising: a torque converter having a torque amplifying function; a clutch mechanism including a first clutch device configured to transmit the driving force of the driving source to the wheels through a power transmitting system of the torque converter so as to move the vehicle, and a second clutch device configured to transmit the driving force of the driving source to the wheels without the power transmitting system of the torque converter so as to move the vehicle; and a selecting device configured to selectively operate the first and second clutch devices so as to transmit the driving force of the driving source to the wheels through the power transmitting system of the torque converter and for transmitting the driving force of the driving source to the wheels without the power transmitting system of the torque converter by operating the first clutch device and the second clutch device in accordance a plurality of different modes of operation of the vehicle, at least one of the modes being a starting mode; wherein a power transmitting system configured to transmit power from the driving source of the vehicle to the wheels comprises the torque converter and a transmission and wherein the clutch mechanism and a variable speed unit are arranged within the transmission; wherein the selecting device is configured to actuate both the first clutch device and the second clutch device in accordance with the condition of the vehicle, and the driving force is thereby transmitted to the wheels through the power transmitting system of the torque converter and without the power transmitting system of the torque converter at an arbitrarily-set ratio, and the first clutch device is arranged downstream of the torque converter in the power transmitting system.
