POWER TRANSMISSION DEVICE FOR FOUR-WHEEL-DRIVE HYBRID VEHICLE

摘要

A power transmission apparatus (11) for four-wheel-drive hybrid vehicle according to the present invention is characterized in that it comprises a front-wheel/rear-wheel driving-force distributor means (21) for distributing rotary powers, which are output from an internal combustion engine (31) as well as a rotary electric appliance (32), between front wheels (91) and rear wheels (93), and then transmitting the rotary powers to them;
wherein the front-wheel/rear-wheel driving-force distributor means (21) sets up the following when braking a vehicle:
a rear-wheel disconnection mode for disconnecting between the front-wheel/rear-wheel driving-force distributor means (21) and the rear wheels (93);
a front-wheel connection mode for connecting between the front-wheel/rear-wheel driving-force distributor means (21) and the front wheels (91); and
a regeneration mode for regenerating the rotary powers from the front wheels (91) by the rotary electric appliance (32).
