Integrated system special for pure electric passenger vehicle

Abstract

The invention relates to an integrated system special for a pure electric passenger vehicle. The integrated system includes a driving motor, a single-stage gearbox and a motor controller. The drivingmotor and the motor controller are fixed and mounted on the two sides of the single-stage gearbox correspondingly. The motor controller and the driving motor are connected through a three-phase line.The single-stage gearbox is provided with a through hole groove and an insulator. The three-phase line is arranged in the through hole groove and fixed through the insulator. By means of the integrated system, the space utilization of an engine cabin can be improved, and electromagnetic interference caused by the too long three-phase line is reduced, so that the layout of the engine cabin is morereasonable, ordered and beautiful.

Description

technical field [0001] The invention belongs to the technical field of pure electric vehicles, and in particular relates to an integrated system dedicated to pure electric passenger vehicles. Background technique [0002] With the development of industry, environmental pollution is becoming more and more serious. Because of the characteristics of zero emission and zero pollution, pure electric vehicles adapt to China's energy-saving and sustainable development guidelines. The factory has set its sights on the field of new energy vehicles, and has developed a variety of hybrid vehicles and pure electric vehicles and other products. [0003] At present, most passenger car solutions in the Chinese market are drive motor and gearbox integration solutions. The gearbox has multiple gears, and the gears are automatically adjusted according to vehicle speed, motor speed, power load and other factors, so as to keep the motor at high efficiency. running state, but the motor controlle...

Problems solved by technology

The transmission with double intermediate shafts realizes the function of reducing speed and increasing torque. The double intermediate shafts can be more stable when outputting high torque, and have a better protection effect on the life of the bearings. High-speed motors are used and the motor shaft is connected to the transmission input shaft and The coaxial design of the transmission output shaft greatly reduces the volume and weight of the system; however, this utility model still needs to leave space for the connection of three-phase lines, and the three-phase lines will cause electromagnetic interference
