Abstract

The invention discloses a dual-mode hybrid power transmission device. The transmission device comprises a planet carrier, a dual-planetary line, a first clutch, a second clutch, a second brake, a first motor, a second motor and an engine, wherein the dual-planetary line comprises a first planetary line and a second planetary line; the first planetary line comprises a first outer gear ring, a first sun wheel and a first planet wheel; the second planetary line comprises a second outer gear ring, a second sun wheel and a second planet wheel; the planet carrier is shared by the first planet wheel and the second planet wheel; the first clutch is connected with the first outer gear ring; the second clutch is connected with the second outer gear ring; the second brake is connected with the second sun wheel; the first motor and the second motor are mounted at one side of the dual-planetary line; and the engine is mounted at the other side of the dual-planetary line and connected with the planet carrier. The technical solution of the invention further provides a hybrid power transmission system. According to the technical solution of the dual-mode hybrid power transmission device and the hybrid power transmission system, the demand of the engine on the property of the motor is reduced, so that the production cost of the system is reduced and the work efficiency of whole vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a dual-mode hybrid power transmission device and a hybrid power transmission system. Background technique [0002] As a new type of energy-saving and environment-friendly vehicle, dual-mode hybrid electric vehicle (also called hybrid electric vehicle for short), its technology and market are in a stage of vigorous development. Compared with traditional vehicles and pure electric vehicles, the biggest difference between dual-mode hybrid vehicles lies in the power system. [0003] Current dual-mode hybrid vehicles generally have two motors and one engine. When the engine is started in a parked state, the rotational speed of the output shaft is zero, and the engine needs two motors to run simultaneously to start, and the power and rotational speed of the motors are required to be relatively large. This not only requires higher performance of the motor, which incre...
