An integrated electric drive system assembly and electric vehicle

Abstract

The invention relates to an integrated electric driving system assembly. The integrated electric driving system assembly at least comprises a driving motor, a transmission, a motor controller, an aircompressor and a water pump which are integrated; a stator shell of the driving motor is connected with an electric control shell, the motor controller is fixed into the electric control shell, and awiring box is formed between a rear end cover of the driving motor and a stator of the driving motor, communicated with the electric control shell and internally provided with a rotary transform signal insertion piece, a temperature signal insertion piece and a three-phase terminal led out of the motor stator of the driving motor; a three-phase high-voltage power output end of the motor controlleris connected with the three-phase terminal through a three-phase copper bar, and a control end of the motor controller is connected with the rotary transform signal insertion piece and the temperature signal insertion piece through a signal line. The integrated electric driving system assembly is compact in structure, the mounting space is saved, the mounting efficiency is improved, the complicated wiring harness connections are omitted, and the overall reliability is improved. The invention further relates to an electric vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicle production design, in particular to an integrated electric drive system assembly and an electric vehicle. Background technique [0002] With the depletion of fossil energy and the aggravation of environmental pollution, electric vehicles are increasingly favored by users. [0003] The electric drive system is the core component of electric vehicles. The electric drive system is a whole that can work in unison formed by the combination of multiple components, including drive motors, motor controllers, transmissions, air compressors, water pumps, high-voltage junction boxes, and Vehicle controller, on-board charger and DC converter, etc. [0004] Each component of the current electric drive system is a split structure, and each component is separately arranged at a corresponding installation position. However, this method has the problem that the electric drive system takes up a lot of sp...

Problems solved by technology

However, this method has the problem that the electric drive system takes up a lot of space, and the various components need to be connected through complex wiring harnesses. Due to the limited layout space of the vehicle, the volume of the drive motor is also limited, which makes the motor's The output power is small, which cannot well meet the power requirements of the vehicle; at the same time, the complicated wiring harness connection between various components also makes the entire electric drive system messy, and the reliability is not well guaranteed.
