Regulator member for steering angle changes of motor vehicle wheels has meshing planet wheels and sun wheels with phased helix angles to generate axial force components

摘要

The steering system incorporates a planetary gear with stepped gears (31) having toothed planet wheels (311,312). The teeth (67,68) of these wheels and those of sun wheels with which they mash, are angled, and the helix angles (beta 1,2) in both transmission stages are phased with each other, so that the tangential forces (Ft1,2) transmitted by the sun wheels into the planet wheels generate axial force components (Fa1,2), which compensate each other.
