An amusement ride vehicle includes a vehicle chassis that rolls on caster
wheels. Pinch drive wheels, driven by on-board electric motors, engage a
guide rail and propel the vehicle along a rack. A motion base is
positioned on top of the vehicle chassis. A yaw ring is rotatably
supported on the motion base. A passenger cabin is mounted on to the yaw
ring. A slip ring assembly extends from the vehicle chassis to the
passenger cabin, to provide electrical power and audio signals to the
passenger cabin. A yaw drive motor turns the yaw ring, allowing the
passenger cabin to spin on the motion base, and to provide continuous yaw
movement. The motion base provides pitch and roll movements, as well as
heave, slip and surge movements.
