Problems solved by technology

[0004] But no matter which kind of hybrid electric vehicle is mentioned above, due to the addition of the motor, the structure of the original power transmission device will inevitably become complicated, the system will become huge, and the axial dimension of the power transmission device will increase accordingly.

Abstract

The embodiment of the invention discloses a hybrid power transmission device, relates to the technical field of power transmission devices and is used for reducing the axial size of the conventional hybrid power transmission device so as to simplify the structure of the hybrid power transmission device. The hybrid power transmission device comprises a crankshaft of an engine, a single-row planetary gear train, a shift mechanism and a motor, wherein the crankshaft of the engine is connected with a gear ring of the single-row planetary gear train through a flywheel; a planet carrier of the single-row planetary gear train is connected with an input shaft of the shift mechanism, and an output shaft of the shift mechanism is connected with a rotor shaft of the motor; and a sun gear is connected with a unidirectional locking mechanism, and a clutch is arranged between the sun gear and the gear ring. The device is applied to hybrid electric vehicles.

Description

technical field [0001] The invention relates to the technical field of power transmission devices, in particular to a hybrid power transmission device. Background technique [0002] A hybrid vehicle refers to a vehicle equipped with more than two power sources, such as batteries, fuel cells, solar cells, internal combustion engines, motors, etc. Currently, a hybrid vehicle generally refers to a hybrid driving form in which the power source is an internal combustion engine and an electric motor. [0003] At present, there are mainly three types of power structures for hybrid electric vehicles. One is a series structure, one is a parallel structure, and the other is a mixed structure. The parallel structure is mainly driven by the engine, and uses the characteristics of the motor to generate strong power when starting. When the fuel consumption of the engine is large such as starting and accelerating, the motor is used to assist the drive to reduce the fuel consumption of the...
