Review article

The design of the power transmission of a special-purpose vehicle with an adjustable magnitude of the kinematic non-coincidence between two different propellers is considered. A mathematical description of the hydrostatic transmission, as well as of wheeled and caterpillar propellers, is presented for their joint operation on a special-purpose vehicle with the possibility of adjusting the magnitude of the misalignment by means of hydrostatic transmission. Based on the calculation studies, the dependences of the magnitude of the kinematic error on the resistance to motion, the torque of the hydraulic motor, and the difference in moments on the driving elements of the wheeled and tracked propellers are shown.
