Disengaging the clutch for each shift out of, and then into, each gear is double clutching or declutching. [4] Due to the absence of a neutral spacing, double-clutching is impossible for sequential gear changes, as with a fully sequential gearbox used in motorcycles and racecars. The double-clutching technique involves the following steps:
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 ...
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.
It is marketed variously under the trade names TCT - Twin Clutch Transmission , Euro Twin Clutch Transmission , [2] TCSS - The Twin Clutch System [3] and Dual-Dry-Clutch Auto Transmission . Able to receive torque inputs of up to 350 N⋅m (260 lbf⋅ft), the transmission is the highest-torque transverse dual-dry-clutch application.(2012) [ 4 ...
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.
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 ...
Instead of a torque converter, it uses a compact wet startup clutch to launch the car from a stop and also supports computer-controlled double-clutching. The MCT (Multi-Clutch Technology) acronym refers to a planetary (automatic) transmission's multiple clutches and bands for each gear. [7]
The I-Shift Dual Clutch has two input shafts which are alternatively connected to the engine through two clutches. When driving, the first gear is engaged by one input shaft while the other one pre-selects the next gear. At the actual gear change, the previously engaged clutch is disengaged as the idling clutch is engaged at the same time.
