Abstract

A power transmission for mixed power vehicles located between an engine and an automatic speed variator consists of a generator, a clutch, a one-way clutch and a planetary gear mechanism consisting of a solar wheel, a planet wheel, a planetary frame and a gear ring. The planet wheel is externally engaged with the solar wheel and internally engaged with the gear ring separately. The output shaft of the engine is connected with the gear ring through a flange, the rotor of the generator is connected with the central shaft of the solar wheel through a spline and the planetary frame is connected with the input shaft of the automatic speed variator through a flange. On the output shafts of the engine and the planetary frame is disposed the one-way clutch separately and between the gear ring and the planetary frame is disposed the clutch.

Description

technical field [0001] The invention relates to a multi-energy input and output device, in particular to a power transmission device of a hybrid electric vehicle. Background technique [0002] At present, there are many forms of hybrid electric vehicle transmission system, including parallel, series and hybrid, and the specific realization of each form is different. The general power synthesis methods are: (1) combine two inputs into one output through a pair of gear pairs to realize hybrid drive; (2) realize four-wheel drive by engine and motor respectively, and realize hybrid drive by synthesizing power on the ground; ( 3) Use a special transmission for hybrid power transmission to realize power synthesis in the transmission. However, the controllability of the first method is poor, and the synthesis and decomposition of motion and torque cannot be realized separately; the synthesis efficiency of the second method is not high, and it is difficult to achieve the ideal ener...
