Abstract: Multiple forces act upon a steering spindle. Further, the mounting support of the steering spindle and the steering spindle itself are affected by tolerances, as a result of which the steering spindle with its longitudinal axis is moved radially relative to the vehicle chassis. Control devices for controlling the vehicle dynamics require steering angle sensors which have to indicate the current steering angle and variations thereof with great precision. If the steering angle is invariably fixed with respect to the chassis frame, the measurement frequently becomes inaccurate due to the radial movement of the spindle axis. As a remedy, the present invention arranges for the steering angle sensor to be positioned in the area of a spindle bearing. Favorable improvements relate to linking the sensor housing to the housing of the spindle bearing.
