Abstract

The invention relates to a dynamic coupling device for a hybrid electric vehicle and a working method thereof. The dynamic coupling device for the hybrid electric vehicle comprises an engine, a first clutch, a front-row bevel gear, a second clutch, a planet bevel gear, a gear ring, a planet carrier, a rear-row bevel gear, a cylindrical gear, a third clutch, a second motor, a fourth clutch and a first motor. According to the working method, the dynamic coupling device has seven working modes: a pure electric working mode, a parking generating working mode, an engine starting working mode, an engine independent working mode, a combined driving working mode, a driving generating working mode and a regenerating brake working mode. The dynamic coupling device for the hybrid electric vehicle can realize the power coupling of multiple power sources through a gear mechanism, can realize various running modes, and can optimize the fuel economy and energy utilization efficiency of the whole vehicle.

Description

technical field [0001] The present invention relates to the field of power transmission, in particular to a hybrid electric vehicle power coupling device. The present invention relates to the power transmission field, in particular to a hybrid electric vehicle power coupling device and its working method. Background technique [0002] With the continuous increase of global car ownership and the continuous consumption of oil resources, the development of new energy vehicles with low emissions and low fuel consumption has become an urgent task for the development of the global automotive industry. Hybrid vehicles have inherited the high efficiency and Low emissions, combined with the power and cruising range of traditional internal combustion locomotives, has become the development trend of new energy vehicles in the world today. [0003] At present, hybrid electric vehicles are divided into three types according to the different connection methods of the motor and the engine....
