Abstract

The invention provides a power assembly of a range extended electric vehicle. The power assembly is capable of reducing vibration damage to a drive motor controller and a power generator controller and is space-saving. The power assembly comprises an engine, a power generator, a differential assembly, and a drive motor, which are sequentially and linearly arranged. The power generator controller and the drive motor controller are integrated to be a master controller. The master controller is fixed above the power assembly through a vibration damping mechanism. Due to the fact that no extra body beams is needed and the power generator controller and the drive motor controller are integrated together, space is saved to the maximum extent. By the aid of the vibration damping mechanism, the vibration damage to the drive motor controller and the power generator controller is reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicle power assembly, in particular to a range-extended electric vehicle power assembly. Background technique [0002] The powertrain of an extended-range electric vehicle is mainly composed of an engine, a generator, a drive motor, a gearbox, a drive controller and other components. At the current level of technology, the engine and drive system and other components are relatively large, and the layout space of the vehicle is limited, requiring a high degree of integration of the powertrain. The engine, drive motor and generator are all vibration sources, and the vibration frequency is high, which is a severe test for the controller directly fixed on the drive motor and engine. Because if it is fixed on the vibration source, the operating conditions for the controller will become extremely harsh, and the internal components will easily cause damage, which will greatly increase the design dif...
