Elektro-mechanisches Überlagerungslenkgetriebe für ein Kettenfahrzeug

摘要

A cross-drive steering transmission for steering a tracklaying vehicle is characterised in that at least two fixed mechanical reduction gears allow for at least two turning radii, in that steering radius automatic switching means are provided between the fixed reduction gears (fixed steering radii) and in that a device allows the driver to input the desired steering radius. Also provided is a control unit that allows switching among a plurality of fixed steering radii depending on the steering radius input by the driver, and thus to approximate the desired steering radius.
