26 HDT • DECEMBER 2014 www.truckinginfo.com Trucking's Worldwide Business Report hotline gl bal Volvo's new I-Shift Dual Clutch V olvo Truck claims to be first in the world to launch a dual-clutch automated mechanical transmission in heavy trucks, and deliveries of the I-Shift Dual Clutch started in Europe this fall. I-Shift Dual Clutch can basically be described as two parallel con- nected gearboxes in one housing. One gearbox contains the even gears and the other has the uneven gears. When one gear is active, the next gear is pre-selected in the second unit. When shifting changes from the first gearbox, the other is poked in. This provides ratio changing without any disruption in power or speed. The I-Shift Dual Clutch has two input shafts, one located inside the other, and the two clutches. This allows two gears to be engaged simultaneously. Which of the gears that is activated is determined by which clutch is engaged. Volvo showed the I-Shift Dual Clutch to the European press corps recently in south-coastal Spain, where there are demanding, long and steep ascents and descents of up to 7 and 8 percent. An FH with a 13-liter, 500-hp engine and 2500 Nm (1844 lb-ft) of torque equipped with the Dual Clutch took off almost like a bul- let and changed gears fast and without any interruptions. One could only hear, not feel, most gear changes. In the long and steep downhills, the transmission shifted down more quickly and more often than otherwise, due to the activated engine brake and retarder. There's no official word yet if the I-Shift Dual Clutch will be available in the U.S., but we think it's likely.

Both Hendrickson and MBHA will now be able to pursue a stand-alone strategy. • China LNG Group is teaming up with Shanghai- based Sinopec Fuel Oil Sales to develop the liq- uefied natural gas market for heavy-duty trucks in China. In a pilot program, LNG fueling facili- ties will be added to existing fuel stations on two highways, connecting Shanghai and Hangzhou and connecting Pudong and Hangzhou. Reporters compared the new I-Shift Dual Clutch to the regular single-clutch I-Shift in Malaga, Spain. Volvo Trucks AROUND THE WORLD
