The fundamental approaches to the design of an electromechanical module that performs the functions of transmitting torque and turning mechanism for a tracked vehicle are considered. Studied features of designing an electromechanical module for transmissions of tracked vehicles. A method for estimating the values of its external parameters is proposed and a structural and kinematic diagram of the electromechanical drive module for the drive sprockets of a caterpillar tractor is proposed based on the principles of designing planetary gearboxes with two degrees of freedom. The features that allow to draw analogies between the considered mechanisms and controlled power distribution mechanisms for transmissions of wheeled and tracked vehicles are reflected. The modes of operation of the proposed mechanism are listed. Dependencies are presented that allow determining gear ratios for various modes of movement of a tracked vehicle. The circuit solution proposed in the chapter seems promising for implementation when creating the chassis of tracked vehicles of small and especially small mass categories.
