ABSTRACT:
A torque distribution control device for a four-wheel drive vehicle includes a rotational speed differential responsive type control coupling combined with a front differential of a front wheel drive line. The control coupling has a variable orifice for varying its torque transfer characteristic and thereby varying distribution of engine torque between front and rear wheels. The orifice opening of the variable orifice varies depending upon a variation of a lateral acceleration of the vehicle, e.g., the orifice opening increases as the lateral acceleration increases.
