2304 ZF will focus on efficiency and reducing fuel consumption at this year’s show. The transmission and driveline component manufacturer will present its Ergopower efficiency package that combines the cPower continuously variable transmission with the ZF Hybrid module that should be commercially available in the future. cPower is a hydromechanical variable transmission that combines hydrostatic drive pumps with a mechanical powershift gearbox. Available for use in a range of machines, including wheeled loaders, telehandlers, graders and wheeled excavators, ZF claims that HVT can save up to 25% in fuel costs. The firm’s hybrid system will be able to be used with all forms of ZF transmission and could be incorporated in the transmission or separately in the machine for additional fuel consumption benefits.
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.

ZF has chosen a pair of radial hydraulic motors for use in its compact single-speed hydrostatic transmission, the 2HC85, which has been developed for compact wheeled loaders up to 100kW and 10.5tonnes operating weight. For high-torque start-up, the transmission sends oil to both motors and demands maximum stroke to travel from 0-16kph, before isolating one motor and then using 100% oil flow through the remaining motor to propel the machine to its maximum travel speed of 42kph. ZF said radial motors afford a
