Title (EN) ELECTRICALLY VARIABLE TRANSMISSION HAVING TWO PLANETARY GEAR SETS WITH ONE STATIONARY FIXED INTERCONNECTION
(FR) TRANSMISSION A VARIATION ELECTRIQUE A DEUX ENSEMBLES D'ENGRENAGE PLANETAIRE AVEC UN INTERCONNEXION FIXE STATIQUE
Abstract: front page image
(EN)The electrically variable transmission family of the present invention provides low-content, low-cost electrically variable transmission mechanisms including first and second differential gear sets, a battery, two electric machines serving interchangeably as motors or generators, and two or three selectable torque-transfer devices. The selectable torque transfer devices are engaged singly or in pairs to yield an EVT with a continuously variable range of speeds (including reverse) and at least one mechanically fixed forward speed ratio. The torque transfer devices and the first and second motor/generators are operable to provide five operating modes in the electrically variable transmission, including battery reverse mode, EVT reverse mode, reverse and forward launch modes, continuously variable transmission range mode, and fixed ratio mode.
(FR)La famille transmission à variation électrique assure des mécanismes de transmission à variation électrique à faible contenu et à faible coût comprenant des premier et second ensembles d'engrenages planétaires différentiels, un batterie, deux machines électriques servant de moteur aux générateurs de manière interchangeable et deux ou trois dispositifs de transfert de couple sélectionnable. Ces derniers sont engagés seuls ou par paires pour produire une EVT selon des vitesses à variation en continu (y compris inverses) et au moins un rapport de vitesse avant mécaniquement fixe. Les dispositif de transfert de couple et les premier et second moteurs/générateurs fonctionnent en cinq modes dans la transmission à variation électrique, y compris le mode inverse batterie, le mode inverse EVT, les modes de lancement inverses et avant, le mode fourchette de transmission à variation en continu et le mode rapport fixe.
