Schematic diagram of a dual- clutch transmission: This shows the layout of two side- by- side single- plate clutches. A dual- clutch transmission, (DCT) (sometimes referred to as a twin- clutch transmission or double- clutch transmission), is a type of automatic transmission or automated automotive transmission. It uses two separate clutches. It can fundamentally be described as two separate manual transmissions (with their respective clutches) contained within one housing, and working as one unit. The first development of the twin- clutch or dual- clutch transmission started in the early part of 1. Harry Webster at Automotive Products (AP), Leamington Spa, with prototypes built into the Ford Fiesta Mk. Ford Ranger, and Peugeot 2. Initially, the control systems were based on purely analogue/discrete digital circuitry with patents filed in July 1. Following discussions with VW/Porsche, DCT work continued from Porsche in- house development, for Audi and Porsche racing cars later in the 1. It is a dual- clutch automatic. DCTs are the fastest- shifting road car transmission available and are even able to shift faster than a professional race car driver using a manual transmission. DCTs can even shift more quickly than cars equipped with single- clutch automated- manual transmissions (AMTs), also called single- clutch semiautomatics. Also, with a DCT, shifts can be made more smoothly than with a single- clutch AMT, making a DCT more suitable for conventional road cars. The original design used a concentric arrangement, where both clutches shared the same plane when viewed perpendicularly from the transmission input shaft, along the same centre line as the engine crankshaft; when viewed head- on along the length of the input shaft, this makes one clutch noticeably larger than the other. The second implementation uses two single- plate dry clutches—side- by- side from the perpendicular view, but again sharing the center line of the crankshaft. A later variation uses two separate but identical- sized clutches. These are arranged side- by- side when viewed head- on (along the length of the input shaft and crankshaft centre line), and also share the same plane when viewed perpendicularly. This latter clutch arrangement (unlike the other two variations) is driven by a gear from the engine crankshaft. Suppliers. Borg. Warner, which call their technology . This joint venture is known as the Borg. Warner United Transmission Systems Co., Ltd., and is located in Dalian, China. The company has produced various dual- clutch transmission modules beginning in 2. Magneti Marelli produces the control system, which integrates Borg. Warner's hydraulic actuation module into its own power and transmission control units. The 7. H AMT Transmission provides seven forward speeds with multiple usage of gears (the electric drive can use unused gears from the combustion engine path): this aims to substantially reduce the complexity of the unit, as well as the package size and weight. Another spin- off from this design was the FEV x. DCT that provides 1. DCT. With use of electromechanical actuation, rather than electrohydraulic, the 6. DCT2. 50 transmission surpasses the conventional manual transmission in fuel consumption and CO2 emission. The first application was the Renault Espace with a 1. L, Turbo GDI engine. Getrag dual- clutch transmissions are used in the BMW M3. Audi originally used the direct- shift gearbox name, but now uses the name . This DQ2. 50 variant is used in a wide range of models: Volkswagen Passenger Cars (Polo, Golf/Rabbit/Golf Plus, Scirocco, Jetta, Eos, Passat, and Touran); Audi cars (A3, and TT); SEAT cars (Ibiza, Le. This unit has seven forward ratios. The DQ2. 00 is again for use in transverse applications, but is intended for use in smaller cars, with smaller- displacement engines that generate relatively low torque outputs. The name of the transmission is 7- speed LDF Dual Clutch . The three modes are strada, sport, and corsa, each with faster shifts. Launch control raises the rotation speed to 4. Using the paddles to call for earlier shifts knocks 0. Kia Motors has announced application of the all- new seven- speed DCT to a production model for the first time, the new Kia Cee’d GT line, which made its global debut at the 8. Salon International de l’Automobile in Geneva on 3 March 2. Compared to the six- speed DCT currently used in the European- market Cee'd models, the new transmission is expected to deliver a fuel- economy improvement of 7% and a 5% improvement in 0–6. Like most new DCTs, the new transmission features dual dry clutches and two input shafts, allowing for seamless torque delivery between shifts, as well as gear- jumping to the optimal ratio, should the driver ask for it. If that were to apply to the current Forte K3 Koup or Pro. Cee'd GT and GT line, with its 2. AHSS Guidelines; Cost Models; Design Advisor; FutureSteelVehicle. FutureSteelVehicle Results and Reports; Steel Eliminates the Weight Gap with Aluminium for. Provides trucking products that improve safety or improve maintenance including grease hubs, freight restraints and tire inflation systems. Description: The new Model 81041 is a portable, self-contained RF Wattmeter that features a studio-quality analog meter and USB interface. Numeric, analog meter, and. L inline- four Gamma II T- GDI Turbo engine and also 1. L CRDi diesel engine, for example, that would raise its fuel economy from 2. The new transmission is the first of its type from the brand, and has been developed in- house by Kia’s research and development teams at its Namyang, Korea R& D centre. More fuel efficient than Kia’s existing six- speed automatic transmission, the new DCT has been engineered with low fuel consumption and a sporty driving feel when in manual mode, and with comfort and smoothness when left in automatic mode. Innovative hollow double- gear input shaft allows quick shifts. The DCT is made up of two dry clutches, each fitted with electric motor- driven clutch actuator to improve responsiveness, and an innovative hollow double- gear input shaft. The hollow shaft itself allows the system to quickly engage even gears, while a solid shaft that runs through the middle operates odd gears.
This crossed gear shifting enables continuous power delivery and more efficient packaging, two development cornerstones for the engineering teams behind the project. The hollow shaft mechanism lets the DCT operate sequentially, the car anticipating the next gear that the driver is likely to need next under acceleration or braking, or jump immediately to any of its seven forward gears (and reverse). This is particularly useful under kickdown or heavy braking, allowing the driver to remain in control of the vehicle at all times. The continuous power delivery of the DCT minimises the loss of torque and forward motion by the powertrain during gear shifts, resulting in more decisive acceleration and a smoother drive. This contributes towards the transmission’s boost to performance in all road conditions in its first application in the Cee’d GT line. Combined with an increase in power from 1. DCT’s seven gears allow the GT Line’s diesel engine to operate at its most efficient speeds at all times. With the engine’s torque increased from 2. Nm, the new DCT is engineered to effectively manage outputs up to 3. Nm, achieving a better balance between the engine’s improved, more effortless performance and potential for greater fuel economy. Reduction of noise, vibration and harshness has also been a focus for the team behind the DCT’s development, with an external damper ensuring a higher level of refinement for the new transmission. After the Cee’d GT line, which will go on sale across Europe in Q4 2. DCT will be made available on a range of other Kia models. In January 2. 00. BMW introduced a dual- clutch transmission for their M3 model, manufactured by Getrag, embedding a Dual. Tronic dual- clutch module from Borg. Warner, and dubbed . The same transmission is used in the second- generation Z4 (the Sdrive. Drive. 35is versions), and is an available option on the 3. The same DCT was used in the M2 (F8. BYD Auto introduced a dual- clutch transmission for its mid- sized family sedan BYD G6. This wet- clutch. Ford also announced the introduction of Power. Shift transmission to North American market by 2. The Power. Shift gearbox will be introduced on the second- generation Volvo S6. The XC6. 0 is expected to get this Ford Power. Shift gearbox along with other new models to make more sporty cars. General Motors. The GM dual- clutch gearbox was introduced on the GMC Granite. Had it been released, the new front- wheel drive transmission would have incorporated the latest innovations for improving fuel economy and performance. The transmission alone would have provide upward of 1. The transmission co- developed between GM and Shanghai Automotive Industry Corporation features dry, dual- clutch technology. It would have provided shift comfort equal to a conventional fully automatic transmission, with superior quality, while reducing CO2 emissions. It is also the only company to pair their DCT with a torque converter to smooth low- speed crawling (a problem found in many traditional DCTs). The Acura NSX super car also uses a nine- speed DCT, which consists of launch gear and a cruising gear while seven gears in the middle are geared closer to each other. The Sport Hybrid versions of the Acura RLX and MDX models both have a 7- speed DCT. Niether the 7 or 9- speed DCTs contain a torque converter as the electric motors of the hybrid system already alleviate the rough slow start issue. Motorcycles. It is the second generation from the six- speed dual- clutch transmission first used on the Honda VFR1. F. 2. 01. 3 Honda introduced the CTX7. DCT, a 6. 70 cc dual clutch motorcycle selling as a 2. The NC line has moved to the 3rd generation as well. In 2. 01. 6, Honda announced that they are studying a DCT for use in sport bikes as well. Hyundai. At the 2. Geneva Motor Show, Hyundai unveiled ix- onic concept car, which was said to feature a six- speed dual- clutch transmission. Currently the transmission is available in the 6. R models, although it will likely be phased out in favour of the new Auto. Power (Auto. Pwr) transmission on the new 6. R and 6. 25. 0R, announced in 2. The tractors are expected to be in full production by mid - 2.
