A steering system for a vehicle having a body supported on at least two
sets of steerable wheels, generally consisting of a steering shaft
provided with a wheel, supported on such body; a torque transmitting main
shaft supported longitudinally on the body; means operatively
interconnecting the steering shaft and the main shaft for transmitting
rotary motion of the steering shaft to rotary motion of the main shaft; a
first transversely displaceable means operatively interconnecting knuckle
brackets of one of the sets of steerable wheels; a steering gear directly
operatively interconnecting the main shaft and the first transversely
displaceable means for translating rotary motion of the main shaft to
linear motion of the first transversely displaceable means; second
transversely displaceable means operatively interconnecting knuckle
brackets of the other of the sets of steerable wheels; and a steering
gear directly operatively interconnecting the main shaft and the second
transversely displaceable means for translating rotary motion of the main
shaft to linear motion of the second transversely displaceable means.
