ABSTRACT:
A torque distribution-controlling apparatus, by which a torque from a driving power source is distributed to vehicle right and left wheels via right and left axles, includes a differential having a first torque transmitting system and a second torque transmitting system, the first torque-transmitting system which transmits the torque from the driving power source to the vehicle right and left axles, and allows differentiation between these right and left axles, and the second torque-transmitting system which is structured to be symmetric to the first torque-transmitting system, transmits the torque from the driving power source to the right and left axles, and allows differentiation between these right and left axles; a left clutch controlling transmission of the torque from the first torque-transmitting system to the left axle; and a right clutch controlling transmission of the torque from the second torque-transmitting system to the right axle.
