Abstract:
1. A steering angle sensing device for vehicle wheel alignment, comprising: a bed section having a pivot pin, the pivot pin having a horizontal axis; a rocking arm pivotally mounted on the pivot pin and swingable around the pivot pin within a predetermined angular swinging range; and a sensing section having at least one sensing point positioned within the swinging range of the rocking arm, the sensing point being centered at the axis of the pivot pin and angularly spaced from a gravity line by a predetermined sensing angle, the sensing section further having a sensor disposed on the rocking arm for sensing the sensing point and a signal generator for emitting a human-perceivable signal; wherein the bed section further has a vertical pole and an elongated slide arm, one end of the slide arm being perpendicularly slidably connected to the vertical pole, the pivot pin being disposed at the other end of the slide arm; wherein the bed section further has a support seat, a lateral face of the support seat facing a sensing end of the sensor, the sensing point being disposed on the lateral face in a predetermined position; wherein the support seat is U-shaped and has an outward diverging open side defined between two lateral boards, the sensing point being positioned on inner face of one of the lateral boards of the support seat.
