Abstract
A front wheel speed-up mechanism for a four wheel drive vehicle when turning, which, when front wheels serve as steering wheels, corrects a delay at the rotational circumferential speed of the front wheels later than the actual moving speed when the vehicle is turning, thereby gradually increasing the rotational circumferential speed of the front wheels in proportion to a length of a turning radius thereof.
