The robotised gearbox with double clutch


Although we found an auto mode and a sequential mode, as a single-clutch AMT, the ISR dual clutch design is very different. It is in fact an assembly of two half-gearboxes. Each has its own clutch.
Thus, when a gear is engaged, the following report is pre-committed to him, which authorizes a change extremely fast speed (less than 10 milliseconds).
Furthermore, the torque transmission is continuous, thereby avoiding any jerk.
In short, dual-clutch AMT combines the advantages of the BVA and ISR single clutch, without their drawbacks.
This type of transmission meeting today a success.

advantages:

driving comfort
auto or sequential mode
consumption gain
passages ultrafast report
cons:

more expensive to buy than a BVA and a BVR
if the passage between the two reports is fast, it is much less so when we want to downshift 2 gears at once and vice versa (uphill).
Some examples: Peugeot DSC, EDC at Renault, Mercedes 7G-DCT, DSG / S-Tronic with Volkswagen and Audi ...
