Abstract
A ball screw drive for a vehicle steering system is provided, with the ball screw drive including a nut configured to receive torque from a power transmission drive. The nut has internal threads, and external threads are provided on the nut or connected thereto for rotation with the nut. A threaded spindle having a spindle thread is provided, with the threaded spindle being drivable by the internal threads of the nut such that rotary motion of the nut is translated into linear motion of the threaded spindle. A rotational angle sensor is provided having a sensor gear that is rotatably driven by the external threads of the nut, and the rotational angle sensor is configured to generate an electric signal based on a rotational position of the sensor gear.
