Abstract

The invention discloses a driving device of a hybrid electric vehicle. The driving device comprises an engine, a first motor, a second motor and a double-planetary-line gear transmission mechanism, wherein the double-planetary-line gear transmission mechanism is composed of a front planetary line and a rear planetary line, the front planetary line comprises a front sun gear, a front planetary gear, a front planetary carrier and a front gear ring, and the rear planetary line comprises a rear sun gear, a rear planetary gear, a rear planetary carrier and a rear gear ring. The driving device is characterized in that a brake is arranged on the front sun gear, the front planetary carrier is connected with the power output end of the engine and is further connected with a spindle of the first motor through a first clutch, the first spindle is further connected with the front gear ring, the front gear ring is connected with the rear planetary gear through a second clutch, the rear sun gear is connected with a spindle of the second motor gear, and the rear gear ring is connected with a power output shaft of a driving device body. The working efficiency of the motors is improved, the fuel consumption of the hybrid electric vehicle is reduced, and the production cost of the hybrid electric vehicle is also reduced.

Description

technical field [0001] The invention relates to a hybrid electric vehicle, in particular to a driving device of the hybrid electric vehicle, and belongs to the technical field of automobiles. Background technique [0002] A hybrid vehicle refers to a vehicle that is powered by two or more drive units that can operate simultaneously. It selects different drive units to provide power independently or jointly according to the actual driving state of the vehicle. According to the classification of power transmission routes, hybrid vehicles can be divided into three types: series, parallel and hybrid. Among them, hybrid hybrid vehicles perform better in terms of fuel consumption and emission performance, so they are considered to be the most ideal. blend mode. The driving device of a hybrid hybrid vehicle includes a small-displacement engine and two motors, which transmit power through the coupling of a gear transmission mechanism. The gear transmission mechanism is divided into...
