QUICKSHIFT SENSOR MANUAL

On a manual transmission, starting from the neutral point (N) of the shift lever, the gear shift process can be split in two phases:

QUICKSHIFT SENSOR SOFTWARE

engine control software which allows torque control during gearshiftĭepending on the vehicle manufacturer, the automated manual transmissions have different commercial names but, in the end, they are the same in terms of functionality:.integration of: input shaft speed sensor, clutch position sensor, gear selection and engagement position sensors, shift lever position sensor, fluid pressure and temperature sensor (in case of an electrohydraulic actuation system).integration of an electronic control module.replacement of the gear actuation mechanism with an electrohydraulic / electric actuator.replacement of the clutch actuation mechanism with an electrohydraulic / electrical actuator.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: 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.

QUICKSHIFT SENSOR DRIVER

In a manual transmission (MT) vehicle the driver takes the decision when to shift and also actuates the clutch and the gears. automated/automatic (manual) transmissions.Sometimes, in the technical literature, the word “transmission” is used to describe the gearbox.ĭepending on who takes the decision to perform a gear shift and the type of actuation of the clutch and gears, there are several types of transmissions: For a better understanding on how a transmission works and why do we need to fit them in a vehicle, read the following articles:Ī vehicle’s transmission usually contains the coupling device ( clutch or torque converter), the multi-speed gearbox, the propeller shaft (for rear wheel drive), the differential and the drive shafts. In a passenger vehicle, the role of a transmission is to adapt the torque characteristic of the prime mover ( internal combustion engine or electric motor) to the road load.
