Abstract

The invention discloses an active drive device for a hybrid electric vehicle capable of independently controlling power output of a left wheel and a right wheel, and the active drive device comprises an engine, a generator, two epicyclic gear trains, a left drive motor and a right drive motor; a first epicyclic gear train is used for realizing the power coupling of the engine, the generator and an input component of a second epicyclic gear train; the second epicyclic gear train is used for realizing the power coupling of the left/right drive motor and an output component of the first epicyclic gear train; the output component of the first epicyclic gear train and the input component of the second epicyclic gear train are connected with each other through a spur gear pair or a bevel gear pair in a driving way; and the left/right drive motor is respectively connected with a left wheel side drive shaft and a right wheel side drive shaft in a driving way. The active drive device has the advantages of compactness in structure, multiple running modes, stepless speed changing of the engine and capability of independently controlling the power output of the left and the right wheels.

Description

technical field [0001] The invention relates to an active transmission device for a hybrid electric vehicle, in particular to an active transmission device for a hybrid electric vehicle which independently controls the power output of left and right wheels. Background technique [0002] In the field of hybrid vehicle technology, various power drive system structures have been proposed, which can be roughly divided into two categories according to their transmission methods: 1) fixed-axis gear trains; 2) epicyclic gear trains. Compared with the former, the latter has certain advantages. First of all, compared with the fixed-axis gear train, the epicyclic gear train has more degrees of freedom, so that the epicyclic gear train can realize more operation modes with fewer parts. Secondly, for active transmissions based on epicyclic gear trains, the engine speed is usually decoupled from the vehicle speed, which is equivalent to realizing continuously variable transmission.
