Dana Rexroth Transmission Systems unveiled the R2 hydromechanical variable transmission (HVT) at Bauma—the latest powersplit system resulting from the 50:50 joint venture between Dana and Bosch Rexroth AG. It is a modular platform that delivers a full suite of configuration options and software controls, such as direct or remote mounting, flexibility in shift control and drive strategy parameters, and the deployment of up to three PTOs. Designed to maximize efficiency and reduce overall vehicle ownership and operating costs, the R2 is ideal for front-end loaders, motor graders, industrial lift trucks, reach stackers, forestry skidders, and other off-highway applications requiring 135 to 195 kW (180 to 260 hp) of engine output power. Initial tests on front-end loaders with Dana Rexroth HVT powersplit systems demonstrate fuel savings in the drivetrain of up to 25% when compared with the same vehicle outfitted with a conventional torque converter transmission.
