As a pioneer of dual-clutch gearbox technology, Audi applied this technology to Audi Sport quattro S 1 RC racing car as early as 1985, and made great contributions to winning many championships. Today, this gearbox technology originated from racing cars leads the development trend of automotive gearbox technology with its unparalleled performance and energy-saving advantages, while Audi continues to maintain its leading position in this field with its 7-speed S tronic dual-clutch gearbox. Engineers in Audi's gearbox department have given a solution-7-speed S tronic dual-clutch gearbox. We can regard it as a mechanical work of art consisting of two sets of manual transmissions, two clutches and an intelligent shift electronic program. Inside the 7-speed S tronic dual-clutch gearbox, Audi engineers learned the innovative structure of Audi quattro full-time four-wheel drive system-hollow shaft. This set of output shaft structure with excellent materials and exquisite workmanship adopts the design of "sleeve shaft" The inner output shaft 1 is associated with the clutch 1 to control the gears of 1, 3, 5 and 7, while the outer output shaft 2 is associated with the clutch 2 to control the gears of 2, 4, 6 and R. All gears are in accordance with 4, 6, 2, r, 1. In order to provide a smoother shift effect, the 7-speed S tronic dual-clutch gearbox with gears 1, 2, 3 and R is equipped with a three-cone synchronizer treated by carbon coating process. The electronic shift program of this gearbox also incorporates the wisdom of Audi technical experts, and the shift is extremely agile. Thanks to such exquisite structural design, the 7-speed S tronic dual-clutch gearbox allows every driver to have more exquisite gear shifting skills than professional racers. What the driver has to do is to put his right hand on the gear lever, push the gear to the S position, and then push the gear lever up and down to complete the gear shift. If drivers want to experience more driving pleasure, the shift paddles located behind the steering wheel can satisfy their passionate hearts. The driver can shift gears instantly without leaving his hands on the steering wheel.
