Abstract:
For use in connection with a hydrostatic transmission comprised of a hydraulic pump having pump pistons and a hydraulic motor having motor pistons in fluid communication through a center section, a bypass mechanism comprising:a rotatable bypass actuator rod having a generally flat surface and an opposite generally arcuate surface; and a plate positioned adjacent to the bypass actuator rod and moveable in response to rotation of the bypass actuator rod from a first position, in which the generally flat surface of the bypass actuator rod is positioned adjacent to the plate and the plate and the hydraulic motor generally impart no force upon the bypass actuator rod, to a second position, in which the plate lifts the hydraulic motor from the center section and the hydraulic motor and the plate generally impart a force on the arcuate surface of the bypass actuator rod that is directed towards the axis of the bypass actuator rod.
