Kia and Hyundai New 7 Speed Double Clutch Transmission

More Efficiency with the Dry Seven-speed Dual-clutch Transmission by Kia And Hyundai Especially as a front-wheel drive, dual-clutch transmissions have to be very compact and efficient to generate driving pleasure. Therefore, Hyundai-Kia developed a seven-speed dual-clutch transmission with dry clutch and electro-mechanical actuation, which is available in two models with 220 and 340 Nm maximum input torque. A transmission length of only 385 mm is very competitive considering this high torque capacity EFFICIENCY, ECONOMY - AND PERFORMANCE Finally the most important issue of this transmission is the efficiency, which is directly related to the fuel consumption. To minimise the inner mechanical friction, needle roller bearings are used at all the idling gears. A roller bearing is located between the two input shafts where high thrust forces exist. The preloads were carefully optimised where tapered roller bearing are supporting the shafts and differential. Because the churning loss in driving condition contributes a lot, a new low viscosity transmission oil has been developed to reduce the drag losses. Compared to the previous manual transmission oil, this new oil showed 49 % lower viscosity at 40 °C. As a result, this transmission showed very high torque transfer efficiency, which is the same level as the manual transmission and one of the highest in this class. Thanks to the high transmission efficiency, the fuel economy of Hyundai-Kia vehicles has been dramatically improved. Depending on the vehicle and engine characteristics, the fuel consumption has been reduced by 6 to 10 % compared to six-speed torque-converter automatic transmission applications تابعونا على: Facebook:   / autotranscenter0   Group:   / autotranscenter   Instagram:   / autotranscenter   Blogspot : autotranscenter1.blogspot.com/ Youtube :    / @autotranscenter9964
