DSG International (Thailand) Public Company Limited (DSGT) was founded on May 20, 1994 (1994-05-20) as a collaboration between DSG International Limited and the Anuwongnukroh family, to produce and distribute disposable baby diapers in the Southeast Asian region. The company was listed on the Stock Exchange of Thailand on August 9, 2006 (2006-08-09).
Associated Hygienic Products LLC (AHP) is a wholly owned subsidiary of DSG that has been manufacturing, marketing and selling disposable baby diapers and training pants for customers in North America since 1984.
The DSG class shunters were built in four batches from 1981 to 1983 and have seen widespread use throughout New Zealand, particularly in larger yards and for port traffic. They also see service on sections of mainline, performing regional shunt duties in a number of areas.
In simple terms, a DSG is two separate manual gearboxes (and clutches) contained within one housing and working as one unit. It was designed by BorgWarner and is licensed to the Volkswagen Group, with support by IAV GmbH. By using two independent clutches, a DSG can achieve faster shift times and eliminates the torque converter of a conventional epicyclic automatic transmission.
At the time of launch in 2003, it became the world's first dual-clutch transmission in a series-production car, in the German-market Volkswagen Golf Mk4 R32, and shortly afterwards worldwide, in the original Audi TT 3.2. For the first few years of production, this original DSG transmission was only available in transversely oriented front-engine, front-wheel-drive and Haldex Traction-based four-wheel-drive vehicle layouts.
The first DSG transaxle that went into production for the Volkswagen Group mainstream marques had six forward speeds (and one reverse) and used wet/submerged multi-plate clutch packs (Volkswagen Group internal code: DQ250, parts code prefix: 02E). It has been paired to engines with up to 350 Nm (260 lbft) of torque. The two-wheel-drive version weighs 93 kg (205 lb). It is manufactured at Volkswagen Group's Kassel plant, with a daily production output of 1,500 units.
At the start of 2008, another world-first 70 kg (150 lb) seven-speed DSG transaxle (Volkswagen Group internal code: DQ200, parts code prefix: 0AM) became available. It differs from the six-speed DSG, in that it uses two single-plate dry clutches (of similar diameter). This clutch pack was designed by LuK Clutch Systems, Gmbh. This seven-speed DSG is used in smaller front-wheel-drive cars with smaller-displacement engines with lower torque outputs, such as the latest Volkswagen Golf, Volkswagen Polo Mk5, and the new SEAT Ibiza. It has been paired to engines with up to 250 Nm (180 lbft). It has considerably less oil capacity than the six-speed DQ250; this new DQ200 uses just 1.7 litres (0.37 imp gal; 0.45 US gal) of transmission fluid.
In September 2010, VW launched a new seven-speed DSG built to support up to 600 Nm (440 lbft), the DQ500.
