An ATV is shown having a steering system comprised of a power steering unit having drive and driven pitman arms coupled to a drag link. The drive pitman arm is laterally offset from a vehicle centerline and is driven by the power steering unit. An alternate power steering system includes a pack and pinion subassembly coupled to a power steering motor, which then couples to steering arms of the ATV.

A vehicle, vehicle frame, and steering system usable with the vehicle and vehicle frame. The steering system including a first and second knuckle mounted to a vehicle frame and configured to rotate with respect to the vehicle frame to turn the wheels, and a pitman arm link rotatable relative to the vehicle frame. The steering system further includes a first tie rod operably connected to the first knuckle to the pitman arm link bracket via a pitman arm and pitman connector, and a second tie rod connecting the second knuckle to the pitman arm link. A pitman connector is rotatably operatively connected to the pitman arm link, wherein the pitman arm thereby transfers pivoting or rotational motion applied via a steering input from the pitman arm to the pitman arm link, to respective knuckles via the first and second tie rods.

The apparatus comprises a rotary to variable linear converter which functions to steer a pivotable rotatable directional wheel of a vehicle.

The converter comprises a driven rotatable cylinder and a rotatable pivotable friction wheel pressed against the surface of the cylinder so that they rotate together. The friction wheel is slidably mounted on guide rods extending parallel to the cylinder surface so that the friction wheel can advance helically along the cylinder if angled relative to the cylinder axis. The friction wheel generates a lateral force which is used to apply torque to the directional wheel to turn it. The orientation of the friction wheel is varied and controlled by a digit-operated control lever operated by a rider of the vehicle.
