![]() Later generations of AMTs had the actuators embedded into them from the early stages of the design phases.Ī conversion from a MT to an AMT requires: #Renault quickshift getriebe manual#To convert a manual transmission into an automated manual transmission, the clutch pedal (1) and the gear shift lever (11) are replaced by electrohydraulic or electric actuators.įirst generations of AMTs were based on the concept of “ add-on“, which means that an existing, already designed MT was converted into an AMT by adding external electronic controlled actuator mechanisms. slave cylinder (concentric slave cylinder, CSC)Īn automated manual transmission (AMT) is basically a manual transmission (MT) with electronic controlled clutch and gear actuators.Image: Main components of a manual transmission (MT) In this article we are going to focus on automated manual transmissions (AMT).Īt a global scale, the market share of automated manual transmissions is quite small, only 1% of the total vehicles sold are equipped with AMT. From the software (function) point of view, both AMTs and ATs, can perform automatic or manual (driver decision) gear shifts. AMTs have constant mesh gears, like a MT, while AT have planetary (epicyclic) gear assemblies. The difference between an AMT and AT is at the hardware level. The clutch and gear assemblies have electrohydraulic or electric actuators controlled by electronic control modules (ECM). In a automated manual transmission (AMT) or automatic transmission (AT), both the decision to perform a gear shift and the actuation of clutch/gears are done automatically without the intervention of the driver. The difference is that the clutch actuation can also be done automatically (by a electrohydraulic or electric actuator) and the gear actuation is still managed by the driver. In an electronic clutch transmission (no clutch pedal), the decision to shift is also taken by the driver. #Renault quickshift getriebe driver#In a manual transmission (MT) vehicle the driver takes the decision when to shift and also actuates the clutch and the gears.
