Abstract
A rotary actuator for a vehicle having an electric/hydraulic motor that is used to rotate a strut tube. The motor is mounted inside the suspension spring and around the tubular portion of the strut tube. A first shaft receives the output of the motor and transfers it to a gearbox that reduces the speed. A second shaft receives the output of the gearbox. A torque rod is attached to the opposite end of the second shaft and transfers the rotation of the second shaft through a semi-circular slot in the spring seat to a annular member. The annular member is further attached back to the strut tube, thus when the motor is energized, the rotation is transferred through the assembly to the strut tube causing it to rotate and steer the road wheel to which it is attached.
