A dualclutch transmission (DCT) (sometimes referred to as a twinclutch transmission or doubleclutch transmission) is a type of automatic transmission or automated automotive transmission.
It uses two separate clutches [1 for odd and even gear sets. Automated manual. While enthusiasts revel in mastering the art of perfectly executed shifts and heeltoe manoeuvres, for many the act of declutching, selecting a gear and clutching is a burdensome A double clutch transmission is a differing type of semiautomatic or automated manual automotive transmission.
It utilises two separate clutches for odd and even gear sets. Show more Hopefully it's becoming clear why the DCT is classified as an automated manual transmission. In principle, the DCT behaves just like a standard manual transmission: It's got input and auxiliary shafts to house gears, synchronizers and a clutch.
Since dualclutch transmissions don't have an inefficient torque converter (like regular automatics) and don't interrupt power flow to the engine, they offer better fuel economy than most traditional automatic or manual transmissions. The best cars with doubleclutch automatic gearboxes While automatic gearboxes arent a new invention, the introduction of doubleclutch gearboxes to the mass market is much more recent.
Doubleclutch units can shift faster not only a regular torqueconverter auto, but faster than any human possibly could with a manual box. The dualclutch automatic is a development of the sequential manual transmission (SMT), which is essentially a fully automated manual transmission with a computercontrolled clutch, intended to deliver stickshift performance with automatic convenience. The dual clutch transmission is quite common in the world of racecars, in variants like the sequential manual gearbox.
Yet in the world of production vehicles it is a new technology, defined by a very specific design known as the dualclutch or directshift gearbox, which might just become the transmission of the future. A dualclutch gearbox is an automatic, and it isn't even the best one. New Cars The fivespeed manual in my Neon race caror the sixspeed manual in my Porsche 993can be taken apart and Summary: If you're shopping for a car and you see the term" automated manual transmission" (or sometimes" automatedclutch manual transmission" ), it refers to a transmission that's mechanically similar to a stickshift, except a computer performs the clutch work.
A dualclutch transmission offers the function of two manual gearboxes in one. To understand what this means, it's helpful to review how a conventional manual gearbox works.
When a driver wants to change from one gear to another in a standard stickshift car, he first presses down the clutch pedal. Dual Clutch Transmissions have been around for quite a while, especially in highpowered performance cars, but the technology has been steadily making its way into more everyday driver consumer cars.
