Why DSG need to be equipped with two clutch system?
In simple terms, a DSG automates two separate “manual” gearboxes (and clutches) contained within one housing and working as one unit. By using two independent clutches, a DSG can achieve faster shift times and eliminates the torque converter of a conventional epicyclic automatic transmission.
How fast does DSG change?
Volkswagen’s DSG takes about 8 milliseconds to upshift. Compare that to the SMT in the Ferrari Enzo, which takes 150 milliseconds to upshift. Instant gear shifts mean faster acceleration; according to Audi, the A3 runs 0-60 in 6.9 seconds with a 6-speed manual and 6.7 seconds with the 6-speed DSG.
Are there any problems with the DSG 6 speed transmission?
1 DSG 6 Speed Demonstration. DSG stands for Direct-Shift Gearbox, and it incorporates the best of both worlds into its design. 2 Juddering/Shuddering. 3 Mechatronic Failure. 4 Noisy Bearings. 5 Five Things You Shouldn’t Do With a Dual Clutch Transmission.
How does a DSG automatic transmission work in a car?
How the DSG Transmission Works. A traditional automatic transmission uses a number of clutch packs to produce the desired output ratio. This works fine, but it has drawbacks, one of the biggest being fuel efficiency. Conversely, manual transmissions use solid metal gears and a single manually operated clutch.
What causes a DSG transmission to judder at lower speeds?
Dual mass flywheels are the source of many juddering problems incorrectly attributed to a DSG transmission. If your flywheel is fine, however, and the juddering sensation is most noticeable on gearshifts—particularly at lower speeds—the problem likely lies in the dual clutch assembly.
What happens when the flywheels wear down on a DSG?
When that flywheel wears down, and the amount of movement is too great, you get a juddering/shuddering sensation. It’s important not to leave this fault for too long. If the two flywheel plates sheer off from each other, your vehicle will lose drive entirely.
