Mobile Equipment Efficiency Management with Servo Controlled Medium Duty Hydrostatic Transmissions

MEDIUM DUTY MOBILE EQUIPMENT CAN REALIZE PRODUCTIVITY GAINS THROUGH THE APPLICATION OF SERVO CONTROLLED HYDROSTATIC TRANSMISSIONS. TO ACHIEVE THESE GAINS, HYDROSTATIC TRANSMISSIONS FOR MEDIUM DUTY VEHICLES MUST POSSESS DESIGN FEATURES WHICH PROMOTE MANAGEMENT OF DRIVELINE EFFICIENCY. HOWEVER, TO ACHIEVE COMPATIBILITY WITH THE MEDIUM DUTY VEHICLE, THESE TRANSMISSIONS SHOULD BE DESIGNED WITH THE COST, LIFE, AND SIZE GOALS OF MEDIUM DUTY IN MIND.

THIS PAPER PROVIDES DEFINITION OF THE MEDIUM DUTY CONCEPT AS IT PERTAINS TO HYDROSTATIC TRANSMISSION APPLICATION AND DESIGN. EXAMPLES OF THE POTENTIAL FOR PRODUCTIVITY ENHANCEMENT THROUGH THE USE OF MEDIUM DUTY HYDROSTATIC TRANSMISSIONS WITH INTEGRATED SERVO CONTROL ARE PRESENTED.
