cally engineered for off-highway vehicles. A concept transmission in the evaluation phase, the Spicer TE- 15HX is an electric parallel hybrid featuring a dual power path trans- mission control system. This system is engineered to continuously moni- tor operating conditions and select the proper combination of diesel and electric power to optimize productiv- ity while reducing fuel consumption, emissions, noise and engine idling. Dana has adopted a neutral stance toward energy storage in the develop- ment of the Spicer TE-15HX trans- mission. Drivetrain systems config- ured with supercapacitors can be used with highly cyclic applications such as front-end loaders, while con- tainer handlers and other applications that permit longer duration charging under a light load can be outfitted to work with lead-acid storage and other conventional battery technologies. Whenever possible, the TE-15HX control system disengages the diesel engine and supplies power from the energy storage system for inching and other vehicle operations that require low energy consump- tion. During idling, it provides power for lights, climate control systems and other electrical accessories. The Spicer TE-15HX transmission incorporates the flexible modular de- sign of the Spicer TE- 15 electroni- cally modulated transmission to coordinate the operation of the diesel engine and a generator. Dana is evaluating three-speed and four-speed versions of the TE-15HX transmission in long-drop and short- drop configurations with an estimated rating of 147 to 235 hp. Company News Dana Holding Corp. has also announced that it will consolidate its Heavy Vehicle Products operations in Kalamazoo, Mich., and Statesville, Dana is also introducing a new, optimized drivetrain solution for 17. 5 ton front-end loader vehicle applica- tions that includes a Spicer 319 sum- ming motor and Spicer Model 114 planetary drive axles. The Spicer 319 summing motor transfer case is designed to provide maximum tractive performance and high efficiency. Targeted for applica- tions requiring 140 to 220 hp, this transfer case employs two hydrostatic motors each with optimized gear ratios. To maximize efficiency at high- er vehicle travel speeds, a clutch auto- matically disconnects the low-speed, high-gear-ratio motor, allowing the high-speed motor to function alone. The Spicer 319 summing motor transfer case delivers seamless con- tinuous variable transmission (CVT) performance from zero to 25 mph, the company said. Dana is also developing new hybrid drivetrain technology specifi-

80 DIESEL PROGRESS NORTH AMERICAN EDITION March 2010 Powershift Transmissions Funk Drivetrain Components by John Deere has published a brochure about its powershift transmissions for ag, con- struction, forestry, mining, aircraft ground support, railroad maintenance and other industries. The transmissions are avail- able in both torque converter and direct- drive options, and are rated for input powers ranging from 150 to 250 hp.

Guardian Couplings Literature is available from Guardian Industries on its Superflex couplings and FBA flywheel couplings. Both brochures include drawings and speci- fications. The Superflex line has appli- cation in light towers, gen-sets, com- pressors and welding sets. The flywheel coupling is targeted toward aerial lifts, skid-steer loaders, excavators and low-mass compressors.
