POWER-SPLIT TRANSMISSION FOR A HYBRID VEHICLE

摘要

The invention relates to a power-split transmission for a hybrid vehicle comprising an internal combustion engine. The transmission has two electric motors (E1, E2) and a number of planetary transmissions (N1, N2, N3, N4). For starting in a first driving mode, a single power-split structure is provided on the input side and is followed by a double power-split in another driving mode. Another single power split for an overdrive follows in a last driving mode.
