Toe-out angle
The toe-out angle enters the angle position of the circle-internal wheel to 
  the circle-outside wheel with a driving along curves. The measurement effected 
  standard in accordance with with a reciprocal steering angle of 20°, enters 
  over mechanical or electronic turning supports.
  Steering element geometry is in such a way designed that the angle position 
  of the front wheels changes with increasing steering angle. A troublefree driving 
  along curves results only, if in each steering wheel position all four wheel 
  axles run by the route card rice focal point. Otherwise erasing and Quiet the 
  tire occur in close curves.
  The toe-out angle informs about the mode of operation of the guidance trapezoid, 
  with correct functioning must equal large values in the case of left and right-hand 
  turn arise.
