Engineering:Dacia Easy-R
The Dacia Easy-R is an automated manual transmission used by Renault and Dacia that uses electro-mechanical actuation (rather than electro-hydraulic actuation) to automate the gear shifts. The Easy-R uses a traditional manual gearbox with a computer-controlled, electronic clutch; the gear shifts are automatic, and the need for a clutch pedal is eliminated.[1] The number of parts has been reduced by a quarter, ensuring better reliability and simplified maintenance.
Easy-R was available in the Logan, Logan MCV, and Sandero models.[2] It was also available in the Duster and currently it is still available in the Renault Kwid and Renault Triber.[3][4] There are two versions: the 5-speed JS3 used in petrol engines and the 6-speed TS4 001 used in diesel engines.[5]
The Dacia Easy-R gearbox was a resounding failure,[5] and now Dacia has switched to using CVT gearboxes on its new models.
Operation
The Easy-R transmission has the following gears: R, N, D, M+, M-
- R is the reverse gear. It is similar to R in both traditional manual and in fully-automatic transmissions.
- N is the neutral gear. It is similar to N in both traditional manual and fully-automatic transmissions.
- D is the drive gear. It is the equivalent to D in a fully-automatic transmission. The gearbox in an AMT car is a manual gearbox, instead of one with a torque converter as in a traditional automatic transmission.
- M- downshifts a gear in a sequential fashion, from M5 (M6 in 6-speed AMT cars) to M1.
- M+ up-shifts a gear in a sequential fashion, from M1 to M5 (M6 in 6-speed AMT cars).
