Dana Holding plans to add freewheel as well as lockup with integral torsional vibration damper on its Spicer powershift transmissions above 90 kW (120 hp). The freewheel and lockup may help OEMs improve overall drivetrain performance and optimize efficiency, according to Dana. The optional upgrades take advantage of mandatory robust freewheel designs for off-highway equipment operating in demanding environments as Stage III/IV and Tier 4 emissions standards continuously encourage OEMs to look for efficiencies throughout the drivetrain. Transmissions and torque converters configured with freewheel and lockup also reduce engine cooling needs, a benefit to designers trying to find space for particulate filters and other devices. Dana offers the features in two configurations: freewheel only, or lockup incorporating freewheel and torsional vibration damper.
