Abstract
A hydrodynamic reversing transmission wherein each of the forward and reverse drive trains between the input and output shafts has a starting torque converter with a stationary housing, a rotary turbine wheel and a set of adjustable guide vanes. The draining lines of the torque converters have inlet portions which are connected with the respective housings and are oriented in such a way that the direction of fluid flow therein is identical with or closely approximates the direction of fluid flow between the adjacent blades of the turbine wheel when the respective torque converters are operated within the counterbraking range. Each inlet portion has an aperture which is in permanent communication with the sump. The ratio of the outer diameter to the inner diameter of each turbine wheel is between 1.1 and 1.25, and the ratio of distances between the tips of neighboring blades of the turbine wheel to the outer diameter of the turbine wheel is between 0.06 and 0.09. One of the torque converters serves as a brake irrespective of the direction of movement of the vehicle as soon as the RPM of the output shaft rises to a preselected value.
