Problems solved by technology

Usually, a hybrid vehicle is driven by the engine when the vehicle is running at high speed, and the power of the pure electric side (motor drive side) cannot be completely decoupled. The consumption will limit the fuel consumption or power consumption of the vehicle, and if the motor is not allowed to work, the design cost of the inverter system will be too high due to the back electromotive force of the motor itself.

Abstract

The invention relates to the technical field of hybrid power vehicles, in particular to a driving device of a hybrid power vehicle, the driving device transmits power from an engine to a half shaft of a driving wheel, and the driving device further transmits power from a motor to the half shaft. A motor shaft and a motor intermediate shaft are arranged in a power transmission path from the motor to the half shaft in parallel, the motor shaft is connected with a rotor shaft of the motor, a motor shaft gear is arranged on the motor shaft, and a motor intermediate shaft pinion, a motor intermediate shaft large gear and a disconnecting assembly are arranged on the motor intermediate shaft. The motor intermediate shaft pinion is meshed with a differential gear of the differential, the differential is connected with the half shaft, the motor intermediate shaft bull gear is meshed with the motor shaft gear, and the disconnecting assembly connects or disconnects power transmission between the motor intermediate shaft bull gear and the motor intermediate shaft pinion. The motor loss during high-speed running of the whole vehicle can be reduced, and the oil consumption and the power consumption of the whole vehicle are further reduced.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a driving device of a hybrid electric vehicle. Background technique [0002] A hybrid vehicle is equipped with an engine and an electric motor as drive sources, and is also equipped with a generator. Usually, a hybrid vehicle is driven by the engine when the vehicle is running at high speed, and the power of the pure electric side (motor drive side) cannot be completely decoupled. The consumption will limit the fuel consumption or power consumption of the vehicle, and if the motor is not allowed to work, the design cost of the inverter system will be too high due to the back electromotive force of the motor itself. Therefore, reducing the motor loss when the vehicle is running at high speed has become an urgent problem to be solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a driving device fo...
