INFINITELY VARIABLE RELATIONSHIP TRANSMISSION WITH POWER DERIVATION WITH TWO MODES OF OPERATION, WHICH INCLUDES THREE EPICICLOIDAL TRAINS.

摘要

An infinitely variable transmission of power bypass with two modes of operation, whose constituent elements are distributed between two power paths that parallel parallel the thermal engine (1) with the wheels (3) of the vehicle, such that these means include at least two first epicycloidal trains (5, 6), two electric machines (2, 4) and a reduction stage (11), characterized in that it comprises governing bodies (8, 9), which cooperate with a third epicycloidal train (7) to establish the two modes of operation of the transmission and to switch between the latter, by simultaneous coupling during the transient mode change phase.
