Abstract

The invention relates to a power transmission device of mixed power vehicle which uses engine and electromotor as power sources, wherein it is formed by an engine, an electromotor, a generator, a clutch connected to the automatic control system, a DCT gear box, and an accumulator; said clutch comprises three clutch couples independent controlled inside one frame; the active blades of clutch couples are fixed on the inner chamber of frame; the driven blade of first clutch couple is driven connected to the input axle of gear box; the driven blade of second clutch couple is driven connected to the another input axle of gear box; the driven blade of third clutch couple is driven connected to the output axle of engine; the frame of clutch via the central axle fixed on one side of frame is driven connected to the rotor axle of electromotor. The invention has high transmission efficiency, high torque capacity, lower cost, and reduced energy consumption.

Description

technical field [0001] The invention relates to a power transmission device of a hybrid vehicle with an engine and an electric motor as power sources. Background technique [0002] The current power transmission devices on hybrid electric vehicles mainly include: ① continuously variable automatic transmission (CVT), ② mechanical automatic transmission (AMT), ③ hydraulic automatic transmission (AT), ④ mechanical manual transmission (MT), ⑤ Planetary gear type power distributor. [0003] And above-mentioned transmission device all has the shortcoming of its own. Solution ① The transmission efficiency is low, the transmitted torque capacity is limited, and the price is expensive. Solution ② is large in size, unable to realize power shifting, and the shifting quality is poor. Solution ③ has low transmission efficiency and high price, which does not match the fuel-saving goal of hybrid power. Scheme ④ cannot realize power shifting, also can not realize automatic shifting, is ...
