ABSTRACT:
To increase the top speed of a multi-speed range hydromechanical steering transmission for tracklaying vehicles, the displacements of the hydraulic motors in the two hydrostatic drive units are abruptly destroked from 100% displacement to 80% displacement at the moment the infinitely variable displacements of their respective hydraulic pumps achieve zero displacement during acceleration through the highest forward speed range of the transmission.
