Hydrostatic transmission controls to simulate gear drive |
摘要 |
A control apparatus is provided for a hydrostatic transmission to simulate a gear drive on a tractor. The hydrostatic transmission has a swashplate that is angularly movable to a plurality of positions, and a proportional valve that provides a control pressure to a servo piston to control the hydrostatic transmission swashplate position. A transmission control lever may be moved to a plurality of positions, each position providing a different voltage signal to a microcontroller. The microcontroller receives and converts a voltage signal to a coil current to actuate the proportional valve.
