Hydrodynamic torque converters are widely used in the transmissions of various purposes self-propelled vehicles. Torque converters are most efficient in trucks, haulers, tractors, and other heavy and utility vehicles operating in variable road conditions and off-road. Torque converters have the ability to automatically control the engine torque, but their torque transformation capabilities are relatively low, which requires the torque converter to be coupled with a multistage gearbox. In addition, the efficiency of the torque converters is significantly lower compared to mechanical gears. In order to increase the efficiency of hydromechanical transmissions, the article discusses technical solutions to develop the operational properties of an automobile and tractor torque converter. The paper proposes a torque converters design featuring two automatic switchable turbines depending on the gear ratio of the torque converter and the conditions of movement of the self-propelled machine. Those solutions make it possible to obtain two ranges through a joint operation of the transmission with the vehicle engine.
