動車のトルク配分装置。 Torque of a four-wheel drive vehicle that divides the torque input from the engine, which is arranged so that the output shaft extends in the width direction of the vehicle body, through the transmission and input gear train and outputs it to the front wheels and the rear wheels. The distribution device is an inter-axle differential device that divides the torque from the input gear train, and includes a plurality of differential devices having different distribution ratios of output torque to the front wheels and output torque to the rear wheels, These inter-axle differentials and a switching mechanism that selectively puts them into a torque transmission state are disposed on the same axis, and a front wheel output gear outputs torque from the shaft to the front wheels and the rear wheels, respectively. When the rotational speed difference between each element of the inter-axle differential device in which the output gear train and rear wheel output gear train are arranged on both sides of the input gear train and is in a torque transmission state exceeds a predetermined amount, A differential limiting mechanism that limits dynamic operation and an inter-wheel differential for wheels located on the engine side are provided on a separate shaft from the plurality of inter-axle differentials and their switching mechanisms, and A torque distribution device for a four-wheel drive vehicle, characterized in that it is disposed between an output gear train for rear wheels.
