ABSTRACT:
A two-wheeled, self-propelled and steerable vehicle especially designed for travel over varying terrain, including pavement, rough and rocky ground, under brush and areas dotted with water. The vehicle has a fore-and-aft body supported on front and rear wheels, both of which are steerable in unison in what may be termed articulated fashion as distinguished from so-called crab steering. Each of the wheels is steerable by a wheel mounting arrangement that eliminates the conventional fork and uses instead a split shaft and splined sleeve interconnection on which the wheel is journaled. Right and left links interconnect the sleeve respectively to proximate right and left fore-and-aft movable shaft carriers for controlling the position of the sleeve as the wheel is steered, thus increasing the range of steerability without increasing the width of the body within which the wheel is confined. Preferably, both wheels are powered by hydraulic motors.
