The HVT R3 from Dana Rexroth Transmission Systems is designed for front-end loaders, graders, forestry skidders, and other off-highway applications requiring up to 360 hp (265 kW). In testing on front-end loaders, the HVT powersplit systems demonstrated fuel savings in the drivetrain of more than 20% when compared to conventional torque converter transmissions. The HVT improves productivity by enabling accurate vehicle positioning and stepless drive with no interrupted acceleration and occupies the same space within the design envelope as conventional torque converter transmissions while allowing for engine downsizing. The HVT optimizes the operating point of the diesel engine by decoupling engine speed from drive speed; maintenance costs are reduced by using hydrostatic braking and wear-free directional reversals.
