ABSTRACT:
To obtain unequal angles of turn for two-steerable wheels of a vehicle inexpensively, each wheel is turned through a gear. The two gears have a center to center distance corresponding to the track of the steerable wheels and are dimensioned to accommodate therebetween a meshing pinion mounted eccentrically on a swing arm. While driving one or each of the gears by means of a steering drive element in the same direction of rotation, the positive engagement of the two gears through the pinion and the eccentric mounting of the pinion on the swing arm produce a larger angle of turn of the wheel running inside the turn as compared to the angle of turn of the wheel running at the outside of the turn. To also ensure a steady, flutter-free straight run of the steerable wheels the swing arm end remote from the pinion is adjustable by a selected amount. In addition, the pinion is designed as a duo-pinion comprising two superposed partial pinions adjustable under the resilient force of at least one interposed torsion spring to reduce the tooth space of the entire duo-pinion. Due to this provision, always at least one tooth of one of the gears is in play-free engagement with the duo-pinion.
