Abstract
A combined tire inflation system and a wheel speed sensor for a vehicle steer axle has a steerable spindle with a substantially hollow interior portion. A shaft, located in the hollow interior portion, connects a rotatable hub cap adjacent the spindle and a sensor at least partially within the spindle. A magnet is secured to the shaft and rotates with the shaft. A sensor is mounted adjacent the magnet for sensing the rotation of the magnet. The shaft has a hollow interior that connects an air source with a tire associated with the hub cap.
