What kind of transmission is used in the Volkswagen Lavida Hatchback?
1 Answers
Lavida Hatchback is equipped with a DSG 7-speed dual-clutch transmission. Overview of the transmission: The automated manual transmission is a gear-shifting device that combines the functions of manual and automatic transmissions. This technology was developed to enhance the fuel efficiency and drivability of automatic transmissions, allowing the shift timing originally determined by the computer to be returned to the driver's control, thereby improving driving operability and enriching the driving experience. Working principle of the transmission: Structurally, the automated manual transmission mainly consists of a conventional gearbox (similar to a manual transmission), an electronically controlled clutch, an automatic gear-shifting mechanism, and an electronic control unit. The electronically controlled clutch automatically engages, disengages, or partially engages the clutch as needed. During operation, the transmission ECU controls a stepper motor to push the clutch fork, thereby engaging or disengaging the clutch. The automatic gear-shifting mechanism automatically selects the appropriate gear as needed, typically utilizing two stepper motors, both controlled by the transmission ECU. The gear lever setup is similar to that of a conventional automatic transmission, with no clutch pedal.
