Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Aiming at the existing defects, the present invention provides a hybrid power system. Firstly, a motor and a two-speed transmission are integrated into the vehicle axle, and the motor drives the differential through a power transmission mechanism. The other motor and engine respectively drive the two input ends of the planetary row, and the other end of the planetary row drives the differential connected to the axle. A locking mechanism is arranged on the engine drive shaft, the drive shaft of the motor outside the axle or the input end of the corresponding planetary row, and the locking mechanism can adopt a multi-disc clutch. Under the premise of realizing dual-motor coupling drive, this solution minimizes the system volume, improves the adaptability of working conditions, reduces the requirements for motor performance parameters, etc., realizes the ...

Abstract

The invention relates to a hybrid power system and a vehicle. The hybrid power system comprises an engine and a drive axle, an in-axle motor is arranged in the drive axle, and the in-axle motor is connected to an output mechanism of the drive axle through a clutch or a gear shifting mechanism with a neutral gear; the system further comprises an out-of-axle motor and a planet row, the out-of-axle motor and the engine are connected to two power input ends of the planet row respectively, and a power output end of the planet row is connected to an output mechanism of the drive axle. And two powerinput ends of the planet row are respectively provided with a locking mechanism. According to the integrated drive axle hybrid power system, besides the in-axle motor of the integrated drive axle, thepower motor is further arranged outside the axle, dual-motor driving can be achieved, the requirement of a vehicle for performance parameters like motor starting torque is lowered, and the power requirement of the whole vehicle is met more easily.

Description

technical field [0001] The invention relates to a hybrid power system and a vehicle, belonging to the technical field of new energy vehicles. Background technique [0002] Environmental pollution and energy crisis are becoming increasingly prominent, and new energy vehicles, as an alternative solution to transportation, are encouraged and supported by the state. Limited by the technical defects of batteries and motors, hybrid electric vehicles have attracted much attention as a transition product from internal combustion engine vehicles to electric vehicles. Since hybrid vehicles have multiple power sources, the coupling and switching between different power sources has become the focus of new energy vehicle design. [0003] The coupling modes between the power sources of HEVs include series, parallel and hybrid. Parallel hybrid systems have huge performance advantages over series hybrid systems and parallel hybrid systems. The Chinese patent document with the authorized ...
