Automated manual transmissions can be semi-automatic or fully-automatic in operation. Several different systems to automate the clutch and/or shifting have been used over the years, but they will generally use one of the following methods of actuation for the clutch and/or shifting: hydraulic or electro-hydraulic actuation, [12] electro-mechanical, [13] pneumatic, [6] [14] [15] electromagnetic ...
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.
Common types of automatic transmissions are the hydraulic automatic transmission (AT) and the continuously variable transmission (CVT). The automated manual transmission (AMT) and dual-clutch transmission (DCT) are internally similar to a conventional manual transmission, but are shifted automatically.
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. [37] The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as one unit.
Mercedes-Benz uses the number "720" to currently "725" to identify automatic, dual-clutch (DCT), Continuously variable (CVT), and automated manual transmissions (AMT).
A direct-shift gearbox (DSG, German: Direktschaltgetriebe [1]) [2] [3] is an electronically controlled, dual-clutch, [2] multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic [2] or semi-manual gear selection.
Ricardo designed and built 7-speed DCT used by the 2005-2015 Bugatti Veyron, [1] [2] [7] [36] which has a turbocharged 16-cylinder engine producing 1,250 N⋅m (922 lbf⋅ft) of torque. Stellantis. Stellantis manufactures the electrified dual-clutch transmission (eDCT) at the Mirafiori Automotive Park in Italy as of 2024. Tremec
Starting in the late 1990s, automotive manufacturers introduced what is now called an automated manual transmission (AMT), which is mechanically similar to, and has its roots in, earlier clutchless manual transmission systems. An AMT functions in the same way as older semi-automatic and clutchless manual transmissions, but with two exceptions ...
