In June 2014, [4] Volvo Trucks presented a new dual-clutch version of the I-Shift, known as SPO2812, with overdrive and a maximum torque of 2800 N·m. [5] The dual-clutch version is only available for trucks up to 540 hp. The I-Shift Dual Clutch has two input shafts which are alternatively connected to the engine through two clutches.
A dual-clutch transmission (DCT) (sometimes referred to as a twin-clutch transmission) is a type of multi-speed vehicle transmission system, that uses two separate clutches for odd and even gear sets. [1] The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as ...
Before the introduction of transmission synchronizers in 1927, [2] double clutching was a technique required to prevent damage to an automobile's gearing during shifts. Due to the difficulty and most often unnecessary redundancy involved in the technique, coupled with the advent of synchronized gearing systems, it has largely fallen into disuse in light vehicles.
The operation of a dual-clutch transmission is analogous to two traditional manual transmissions, each with its own clutch, operating in parallel and alternating shifts. The Ford unit is a six-speed with one clutch acting on reverse, first, third, and fifth gears, and the other used for second, fourth, sixth gears.
These are dual-clutch transmissions. 2008–present 6DCT 150 6-speed wet clutch. Ford Fiesta; 2008–present 6DCT 250 (DPS6) 6-speed dry clutch. Ford EcoSport, Ford Fiesta, Ford Focus. The 2012-2016 DPS6 Powershift transmission was used in the 2012–2016 Ford Focus and 2011–2016 Ford Fiesta sedans. This transmission is the subject of a ...
Historically, a dual-clutch transmission shifts faster than a standard hydraulic automatic transmission with a torque converter or a single-clutch automated manual transmission. This is possible because the DCT can pre-select the next gear and transfer torque from one clutch to the next clutch with the pre-selected next gear, thus reducing ...
A dual-clutch transmission (DCT, sometimes referred to as a twin-clutch transmission, or double-clutch transmission) uses two separate clutches for odd and even gear sets. [36] The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as one unit.
Rated up to 23.5 kg⋅m (230 N⋅m; 170 lbf⋅ft) while having a dry weight of 79.9 kg (176.1 lb). It is contracted by Chrysler Group LLC for use in 2013–2016 Dodge Dart and 2014-2016 Jeep Compass and Jeep Patriot, the transmission is designed to be maintenance-free under normal use and is assembled in South Korea.
