FIELD: transport machinery.

SUBSTANCE: this invention covers crawler-type vehicles. A steering device includes two differentials (1, 2) and auxiliary source of torque (3). Input element (4) of the first differential is connected to the drive. Output elements (5, 6) of the first differential are connected to input elements (8, 9) of the second differential so that the output elements of the second differential rotate in opposite direction. Input element (7) of the second differential is connected to auxiliary source of torque (3).
