At INTERMAT 2012 Dana Rexroth Transmission Systems unveiled the R3 hydromechanical variable transmission (HVT), the first powersplit system resulting from the 50-50 joint venture between Dana and Bosch Rexroth AG.

  • Demonstrates fuel savings of up to 20%
  • For use with front end loaders, graders, forestry skidders and other off-highway applications requiring up to 265 kW (360 horsepower)
  • Improves productivity by enabling sensitive, precise vehicle positioning and stepless drive with no interrupted acceleration
  • Occupies same space within design envelope as conventional torque converter transmissions while allowing for engine downsizing
  • Uses only hydrostatic circuit at low vehicle speeds, allowing for quick acceleration and braking, precise low-speed maneuvering, and reversing without need of additional clutch
  • As vehicle speed increases, power splitter routes engine power through parallel path that uses mechanical elements, enabling acceleration with no interruption in tractive force
  • Optimizes operating point of diesel engine by decoupling engine speed from drive speed
  • Reduces maintenance costs by utilizing hydrostatic braking and wear-free directional reversals
  • Management via advanced electronic control unit (ECU) reduces complexity
