1. An electro-mechanical drive system for a full-track vehicle, comprising:

  • an electric drive motor for driving track-driving wheels of the vehicle;

    at least one steering control unit in the form of an electric motor for controlling the track-driving wheels so as to steer the vehicle, wherein the drive motor and the steering control motor are supplied with electric energy from an electric generator which is driven by an internal combustion engine;

    a differential gear arrangement including two differential gear sets connected to the track-driving wheels of the vehicle;

    a drive control connection between the drive motor and the differential gear arrangement;

    a steering control connection between the steering control motor and a steering control element of the differential gear arrangement;

    wherein the drive control connection comprises first and second portions of a drive shaft disposed between the differential gears, and the drive motor is disposed coaxially about and in driving engagement with the first drive shaft portion, and the steering control motor is disposed coaxially about the second drive shaft portion;

    and two control outputs of the differential gear arrangement disposed coaxially with the first and second drive shaft portions for driving the track-driving wheels, whereby both the drive motor and the steering control motor are disposed between differential gear sets, and said first and second drive shaft portions are coaxial with respect to the axis of rotation of the track-driving wheels.
