La transmission à variation continue

-

If you have ever driven a "moped", you've already dealt with the principle of continuous variation! The speed varies gradually, without gearshift.
The most common system is composed of a metal belt and pulleys, the conical winding diameter varies automatically according to the engine speed.
Some models are still a batch mode, allowing the driver to pass himself reports using a lever.
For now, its high cost of production usually reserve this type of transmission in high-end models.

advantages:

driving comfort (fresh Conduct)
operation totally devoid of jerks
range of high variation (equivalent to a minimum of 6 classic reports)
auto or sequential mode available
cons:

overconsumption nervous reactions (literally Braille engine during hard acceleration, and says braille says consumes ...)
grip that can be disconcerting
no performance driving
Some examples: Nissan Xtronic, Autoronic Mercedes, Audi Multitronic ...

Outils spéciaux / Equipement d'atelier et outillage standard Kit de testeurs de bornes 29-011A Multimètre digital. Outil de diagnostic. Contrôle et vérification Note : Le module électronique générique (GEM) fait partie du boîtier électrique central (CJB). Note : Si le module GEM est remplacé, le module neuf doit être configuré après la pose. A cet effet, les données spécifiques au véhicule sont extraites du module à remplacer à l'aide de l'équipement de diagnostic et sont transférées dans le module neuf. Note : Avant d'extraire les données spécifiques au véhicule, s'assurer que toutes les connexions électriques du véhicule sont de nouveaux raccordées, de sorte que le module et l'outil de diagnostic puissent communiquer correct
