Abstract:
1. A power transmitting apparatus for a hybrid vehicle comprising a first and second power distributors each having an input shaft to which a rotational drive power from an engine is transmitted, a power output shaft to which a first output shaft of two output shafts of said first power distributor and a first output shaft of two output shafts of said second power distributor transmit rotational drive powers and which output the transmitted rotational drive powers to drive wheels of the vehicle, a first motor that applies a drive torque or regenerative torque to a second output shaft of said first power distributor, and a second motor that applies a drive torque or regenerative torque to a second output shaft of said second power distributor, a speed reduction ratio for a rotation transmitting system from said engine to said power output shaft via said first power distributor having a value different from a value of a speed reduction ratio for a rotation transmitting system from said engine to said power output shaft via said second power distributor, wherein the apparatus comprises first clutch means for connecting and disconnecting said engine to and from the input shaft of said first power distributor for rotation transmission, second clutch means for connecting and disconnecting the first output shaft of said second power distributor to and from the power output shaft for rotation transmission, first rotation regulating means operating in an open state in which the input shaft of said first power distributor is rotatable and in a braking state in which the input shaft is inhibited from rotating, and second rotation regulating means operating in an open state in which the first output shaft of the second power distributor is rotatable and in a braking state in which the first output shaft s inhibited from rotating.
