Skoda Produces 2 Million Dual-Clutch DQ200 Transmissions
Skoda announced that the company’s factory in Vrchlabi, Czech Republic, achieved a significant milestone of 2 million produced dual-clutch transmissions DQ200. The factory in Vrchlabi became of the Skoda manufacturing network more than 70 years ago.
According to the press service of Skoda, it
took 5,5 years to reach such an impressive number of produced transmissions.
The production of DQ200 was launched in 2012. Currently, the factory in Vrchlabi
produces about 2200 of DQ200 transmissions per day. This transmission is mainly
installed in Skoda models and other brands of the VW concern.
For the last 5 years Skoda and Volkswagen Group invested about 250 million Euros in production of DQ200. Moreover, the factory also uses the advanced technology named as Transparent Factory. This system was introduced in 2017 after a long-term planning. In 2015 the factory in Vrchlabi introduced the robot unit, which was used for the assembly of DQ200: this unit was applied by the engineers at the stage of installing the shifting cylinder piston.
The 7-speed transmission DQ200 with the east-west
positioning was released in 2008. The torque capacity of this transmission is
equal up to 250 Nm. DQ200 was designed for operation with engines having the
capacity from 1,2 liters (FSI) up to 2.0 liters (TDI). This transmission was
mainly used for VW models such as Golf, Golf Plus, Polo, Scirocco and others.
DSG transmission
The direct-shift gearbox (DSG) is a separate
type of automatic transmissions with the dual-clutch, controlled with the help
of electric motors instead of hydraulic control system. This type of
transmission also may be called as an automated transmission.
This type of transmission uses a proven advantage of manual transmissions – the clutch is located outside the transmission and wear products are immediately removed without any harm to the transmission. This type of transmission uses neither planetary gears nor hydraulic gear-shifting control. All gear shifts are performed with the help of two forks controlled by a compact hydraulic Mechatronic, which approximately contains 1 liter of oil. It helped to reduce the production cost at the expense of the transmission resource. DSG transmissions commonly have 6 or 7 speeds. The 7-speed transmission (with the torque up to 250 Nm) is usually used for cars of B, C, and sometimes D class. The 6-speed models have the torque capacity of up to 350 Nm and are installed in more powerful vehicles. The main advantages of DSG transmissions are high efficiency and good dynamics. The principle of operation of DSG transmission lies in sequential actuation of speeds of both gear sets. When one gear is activated, the next one is already selected and is ready to be switched on.
