AUDI - S tronic Transmission

S tronic | innovaton Discoveris #InnovationDiscoveries The S tronic dual-clutch transmission is a successful technology. It combines the convenience of an automatic with the efficiency of a manual transmission, while adding its own dynamic touch. Throughout much of the model line-up, the S tronic is available in four different versions, with six or seven gears. For longitudinally installed engines, Audi has developed a special version of the seven-speed S tronic in which the gear wheels for all gears are situated one behind the other on an output shaft. The three versions for transversely installed engines are configured in a single layout with two output shafts, allowing a compact design. The S tronic for transverse engines is available with six or seven gears. The seven-gear S tronic itself has two versions. Which version is used with which engine depends on the amount of torque to be transmitted. The following is a description of the seven-speed S tronic for longitudinal engines; however, the basic principle is the same for all designs. The S tronic comprises two subunits and integrates two multi-plate clutches that control the various gears. The large K1 clutch located on the outside directs the torque via a solid shaft to the gear wheels for the odd-numbered gears 1, 3, 5 and 7. A hollow shaft rotates around the solid shaft. It is connected to the smaller K2 clutch, which is integrated into the inside of its larger sibling, and which controls the gear wheels for...
