Renault New dedicated hybrid transmission for B and C segment: Article technique redige a l'occasion du congres SIA Powertrain & Electronics

摘要

Renault is developing a new Hybridized powertrain to extend pure EV driving and to meet CO_2 regulation challenge. Thanks to compact packaging, this new powertrain allows the hybridization of B & C segment. This paper presents Renault's electrified gearbox and in detail the innovative transmission technology. E-Tech has a flexible structure allowing full electric driving/parallel and series hybrid/pure ICE modes. It can meet best CO_2 requirement. E-Tech can also achieve EV-ness with a direct drive feeling. These are the key points for customers with respect to Renault's knowledge of EV-adopter's. A strong focus is made on a new state of the art gear shift process and friction reduction. Theoretical and vehicle test results obtained from the dog-clutch gearbox technology proves the robustness and the excellent level of functionality. Finally we explain how Renault will introduce this new power-train in its line-up.
