DQ381 - The Latest Generation of Dual-Clutch Transmissions from Volkswagen

摘要

With the DQ381 dual-clutch transmission, Volkswagen presents a new member of its extremely successful DSG family. The DQ381 is the successor to the DQ250, which has been in series production at the component plant in Kassel since 2003 as the world's first dual-clutch transmission. The new DQ381 has seven gears and is designed for torques up to 420 Nm. Like all of Volkswagen's dual-clutch transmissions, it provides sporty performance without compromising on comfort and efficiency. Its variable design allows it to be used in a wide range of models in the Volkswagen Group. It has been designed both for front-wheel drive and four-wheel drive models. It was developed on the basis of the modular assembly matrix for transmissions with oil-cooled dual clutches with the goal of increasing the efficiency throughout the design. To this end, a number of optimizations were made in particular. The DQ381 completes Volkswagen's range of transmissions for the complete line of products using conventional powertrains. From the small-car segment up to the Transporter line of models, all are now available with 7-gear transmissions (Fig. 1).
