Chrysler dual-clutch transmission has been announced by Chrysler. Chrysler dual-clutch transmission will debut in the international market. Chrysler dual-clutch transmission was developed in collaboration with Getrag. Offers a reduction in CO2 emissions by 6%, Chrysler dual-clutch transmission will improve fuel economy. With quick acceleration and smooth on offer, Chrysler dual-clutch transmission will make its debut spring of 2009 Dodge Journey 2009 Dodge Avenger and 2009 Chrysler Sebring.
Chrysler new vehicle dual-clutch transmission, developed in partnership with Getrag, makes its debut this spring. New technologies available in international markets in 2009, all-new Dodge Journey, 2009 Dodge Avenger and 2009 Chrysler Sebring-will give consumers improved fuel economy and CO2 emissions reduction of 6 percent.
" New Chrysler dual-clutch transmission is the next step in transmission technology, offering consumers increased fuel economy along with smooth and fast shift," said Frank Klegon, Executive Vice President - Product Development. "This new technology is important Chrysler is one of several initiatives we have in place to directly focus on improving fuel efficiency across our vehicle line." Chrysler's commitment to dual-clutch transmission technology is part of the Company powertrain offensive, announced last year .
Dual-clutch Transmission Technology Chrysler's increasing fuel economy and CO2 emissions by reducing parasitic losses-first, by eliminating the torque converter, and second, through the use of synchronizers instead grip the first shift.Dalam Chrysler LLC vehicle applications, the new dual-clutch transmission will debut in international markets in 2009, all-new Dodge Journey, 2009 Dodge Avenger and 2009 Chrysler Sebring. This will be mated with 2.0-liter diesel engine turbo. Dual-clutch transmission is an automatic transmission which utilizes dual launch and shift clutches with a lay-shaft gear arrangement style manual transmission, and not a conventional torque converter and planetary gear. One clutch drives the odd-numbered gears and reverse, while the other clutch drives the even teeth. During shifts, the next gear is anticipated and pre-selected. Then one clutch is opened while the other is closed, so shifting without torque interruption. The result is quicker acceleration and refined shift quality. Furthermore, with the lay-shaft arrangement of gears, there is increased flexibility to optimize gear ratio selection performance and fuel economy.
Dual-clutch transmission that does not require all-new torque converter to transfer engine torque to the transmission. Instead, use two multi-plate wet clutch. With the wet multi-plate clutch, clutch components are bathed in lubricating / cooling fluid in order to provide adequate thermal capacity, multi-plate clutch system uses hydraulic pressure to run the clutches and provide for the selection of gear. With this system, the flow of power from the engine to the transmission is not interrupted during a shift, producing a power-on shift. This means that there is less torque disturbance than a conventional planetary automatic transmission with torque converter. In addition, by eliminating the torque converter and reducing the number of shift clutches, parasitic losses caused reduced fuel economy.
