Abstract: A steering turntable for a wheeled vehicle includes an upper support plate, a lower support plate rotatably supporting steering wheels of a vehicle, and an isolation plate mounted between said upper and lower plates to reduce steering forces required to steer the vehicle, with the isolation plate carrying multiple bearing elements. The isolation plate includes a pair of parallel bearing plates and is provided with multiple registering apertures cooperating with one another to define multiple cavities. Each of the cavities supports a spherical or spheroidal bearing element, and each cavity is defined by a truncated curved surface terminating in openings in the outer surfaces of the bearing plates so that the bearing elements project above their corresponding bearing plates to engage the upper and lower support plates, respectively.
