A Hydrostatic Transmission for Medium Power Applications 861289

Recent developments in hydrostatic transmissions (HST's) and their controls have made this method of propulsion very suitable for medium-powered vehicles. For the purposes of our discussion, these machines are assumed to be in the range of 20 to 60 horsepower [15-45 kW]. Typically included are the following: A. Small Industrial Utility Tractors (Loader/Backhoes) B. Airport Towing and Baggage Handling Vehicles C. Golf Course & Turf Machinery D. In-Plant Type Utility Vehicles E. Municipal Vehicles Sidewalk Sweepers Sidewalk Snowplows Parking Lot Cleaners F. Skidsteer Loaders G. Forklift Trucks H. Small Compactors, Rollers and Pavers I. Railway Maintenance Vehicles J. Trenchers The development of these new HST's and their controls has provided certain advantages. These advantages are realized in the areas of better horsepower-to-weight ratio, torque utilization, power density, engine characteristics, and overall vehicle dynamics and efficiency.
