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.
ZF used bauma 2013 to show the next stage of development for its cPower continuously variable transmission (CVT). By combining the transmission with a hybrid module, ZF said greater operating efficiencies were available from the integration of start/stop technology and energy recovery from regenerative braking. Potentially, the hybrid drive system has the ability to boost fuel efficiency by up to 25% in addition to the 20% higher operating efficiency already offered by the cPower transmission, said ZF.

Hatz Diesel will take the wraps off a new engine family at Bauma, with the launch of the H series, a 2.0–litre water-cooled engine family that features Bosch common rail fuel injection with pressures up to 1,800 bar. Producing 56kW (75hp) and 130Nm of torque, the engine meets European Stage IIIB emissions regulations and US Tier 4 Final standards. The engine, a first at this size for the company with liquid-cooling, uses exhaust gas recirculation (EGR) and a diesel oxidation catalyst (DOC) but does without
