Dana Rexroth will launch the high-efficiency R2 hydromechanical variable transmission for smaller machines

First publishedbauma
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. The hydrostatic drive unit is mounted outside the mechanical gearbox, for ease of maintenance and the combined HVT can be equipped with up to three power take-offs, including hydraulic drive for cooling fans.
