AMT Automated Manual Transmission Magneti Marelli. Automated Manual Transmission AMT, also called Freechoice from Magneti Marelli is a electro hydraulic mechanism for automating manual transmission which derives from Formula 1. It combines comfort of use with a reduction in consumption, and can be applied to any transmission, with production costs that are consequently lower compared to traditional automatic transmissions. AMT is based on an electronic control unit and a hydraulic system that supervise the use of the clutch and the gear shifting, allowing the driver to change gear without using the clutch, either sequentially or fully automatically. Providing the smooth gear shifting of an AT. The torqueassist AMT combines the seamless shifting of an automatic with the superior. POWER ASSISTED HYBRID GEAR SHIFTING SYSTEM IN. POWER ASSISTED HYBRID GEAR SHIFTING. Automated Manual Transmission AMT. AUTOMATIC GEAR SHIFTING MECHANISM ABSTRACT This paper is based on the project Power Assisted Gear Shifting Mechanism for Automobiles. This is a design. The device from Magneti Marelli operates on the manual transmission of a car in the same way as the driver would it opens and closes the clutch, engages and disengages the gears and, when necessary, it also controls the choice of transmission automatic or sequential mode for changing gear. These three control movements are ensured by three specific hydraulic actuators, controlled by hydraulic electro valves. All the components in the hydraulic unit are gathered together in a single kit. It is delivered to the car manufacturer sealed and ready to be installed in the gearbox. Led Sign Design Program. Once assembled in the gearbox, the hydraulic kit mechanically interfaces with the gear drive shaft. The heart and intelligence of the gear control system is the TCU Transmission Control Unit. Taking into account the drivers requirements and the operating conditions of the vehicle, it manages the gear changes by controlling the clutch, the gears and the engine. Thanks to the electronic optimization of the gear change and the coupling with the engine control means the AMT is able to ensure less consumption than a car with manual transmission lower consumption also means lower emissions, especially of CO2. In some of the best applications of the AMT on mass production automobiles, a 5 reduction in fuel consumption was recorded compared to the automatic transmission version of the same automobiles, as well as a reduction in emissions equal to 5 gkm of CO2. The latest generation of AMT is known as mechatronic, as for the first time, it combines the electronic control part and the hydraulic actuation part of the transmission in a single kit. This allows considerable improvements to performance, both in terms of speed and comfort when changing gear. An 8gear automatic transmission. Manual. So automatic gear shifting system is costly than manually gear. What is Auto Gear Shift or AMT or EZ Drive or clutchless or semiautomatic or automatic manual. Design and Fabrication of Hand Operated Gear. Manual Transmission Gear Shifting.

The product is still undergoing sharp growth in performance.
