Abstract
A steering wheel drive assembly for steerable wheels of vehicles. A hydraulic motor is provided for driving the wheel and includes a fluid distribution assembly located between the bearing assembly and piston drive assembly. Upper and lower bores are provided in the distribution assembly cover and extension arms attached to the vehicle chassis extend over the bores and are provided with pivot pins detachably attached to the extension arms and extending into the distribution cover bores. The distribution cover bores are coaxial and thereby allow the fluid motor to pivot about an axis of rotation. The motor axis of rotation is preferably colinear with the vertical center line of the steerable wheel. Sleeve bearings are provided within the distribution cover bores and thrust bearings are provided inbetween the extension arms and the distribution cover.
