Abstract

The invention discloses a power coupling device and a control device thereof, and a hybrid power system. The power coupling device comprises a front planet gear train and a power transmission mechanism; a planet carrier of the front planet gear train is provided with a first clutch connected with an engine; power shafts of a small sun gear and a big sun gear of the front planet gear train are connected with a first motor and a second motor; the power transmission mechanism comprises a first transmission mechanism connected with a second motor, and a second transmission mechanism connected with the front planet gear train; the first transmission mechanism and the second transmission mechanism are connected with a second clutch and a third clutch; the first clutch and the second clutch are coaxially arranged on a clutch shaft; and the clutch shaft is provided with a power output mechanism connected with a power input mechanism on an automobile. By the technical scheme, various operating modes of a hybrid power automobile and the reasonable distribution of power output by the engine and the motors under various modes can be realized, so that the fuel economy of the hybrid power automobile is improved.

Description

technical field [0001] The invention relates to hybrid power technology, in particular to a power coupling device, a control device thereof, and a hybrid power system. Background technique [0002] With the improvement of people's awareness of environmental protection and the depletion of energy, the use of clean energy is becoming more and more extensive, especially in the field of automobiles. It has become a development trend to use electric energy to provide power for automobiles. Due to the limitation of technical conditions, the application of pure electric vehicles has been restrained to a certain extent, while hybrid electric vehicles can be powered by electric energy and traditional energy, making hybrid electric vehicles the focus of current research and development in the automotive field. [0003] At present, the power system of a hybrid vehicle generally includes an engine, a motor, a power battery, a transmission and an electronically controlled clutch, which c...
