2254 Dana Rexroth’s HVT R3 is a hydro-mechanical variable transmission for wheeled loaders with engine outputs of up to 265kW and is the first power split transmission from the joint venture between Dana and 2253 Bosch Rexroth
Using a combination of hydrostatic and mechanical drives, the technologically advanced three-range transmission can offer up a fuel saving of up to 20% by delivering a stepless speed range from 0-40km/hr without clutches and without interrupting the drive.
Cleverly, the HVT R3 will allow the operator to preset a maximum travel speed, or preselect a fixed engine rpm and use the transmission’s characteristics to keep the engine working at its most fuel-efficient point.
Dana Rexroth Transmission Systems, the joint venture Dana and Bosch Rexroth, is to launch the R2 hydromechanical variable transmission (HVT). The modular transmission uses both a hydrostatic drive and a mechanical gearbox to deliver fuel savings of up to 25% compared to a torque converter transmission. Designed to work with engine outputs of 134-193kW (180-260hp), the R2 is suitable for use in wheeled loaders, motor graders, lift trucks and a variety of off-highway applications.
