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

5378 Dana Rexroth Transmission Systems, the joint venture Dana and 2253 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.
Dana Holding Corporation used bauma 2013 to reveal its Spicer TE30 powershift transmission for heavy-duty materials handling applications. With five forward and three reverse speeds, the TE30 slots into the range between the TE27 and TE32 transmissions, and is compatible with engines ranging from 225-300kW. The Spicer TE30 transmission benefits from several engineering refinements to improve efficiency. These include decreased spinning speeds of internal components to lower oil churning losses, optimised cl
