摘要

The arrangement has a steering wheel-sided driven gear wheel (1) engaged with a wheel-sided gear rod (2). Teeth of the gear wheel are formed by two identical conical spirals, which exhibit a common smallest pitch circle diameter, where the spirals form a center position of the teeth of the gear wheel. The gear rod is equipped with flanks (24, 25) arranged at an obtuse angle to each other, and teeth are formed at the flanks, where the flanks form a common point, which act as the center position of the teeth.
