Abstract
A four-wheel steering system in a wheeled vehicle comprises a front-wheel steering linkage, a rear-wheel steering linkage including a lateral control shaft operatively connected at its opposite ends with a pair of rear steerable road wheels, and a rear-wheel steering mechanism for interconnecting the steering linkages. The rear-wheel steering mechanism comprises a housing mounted on a vehicle body structure for axially slidably and rotatably supporting thereon the control shaft, a first cylindrical carrier body mounted within the housing for rotation about a vertical axis perpendicular to the central axis of the control shaft and arranged to be rotated in response to operation of the front-wheel steering linkage, a second cylindrical carrier body mounted within the first carrier body for rotation about the central axis of the control shaft, a radial rod integral with the control shaft and arranged within the interior of the second carrier body, the radial rod extending perpendicular to the central axis of the control shaft, a universal joint mounted within the second carrier body for slidably supporting the radial rod, and an actuator assembly mounted on the housing for rotating the control shaft.
