Abstract

The invention relates to a pure electric integrated power assembly for a small-size passenger car. The pure electric integrated power assembly comprises a driving motor, a gearbox and a controller. The driving motor and the controller are arranged on the two sides of the top of the gearbox correspondingly to form a T shape, the driving motor is connected with the gearbox through a spline, and thecontroller is in bolted connection with the gearbox. An inner shell channel is formed in the gearbox, and the controller and the driving motor are connected through a triple-phase line penetrating through the inner shell channel. According to the pure electric integrated power assembly, the driving motor cooperates with the gearbox to meet the requirements for the driving property of the car in diversified road conditions through the speed reduction and torque increasing functions of the gearbox. The motor can work in a high efficiency area for a long time by being matched with the appropriaterevolution speed of the motor when climbing a slope and being started up, thus the economic performance of a driving system is improved, and the endurance mileage of the car is prolonged. Meanwhile,the gearbox and a differential are integrally designed, the whole system is compact in structure through reasonable spatial arrangement in a gearbox body, and the pure electric integrated power assembly is more suitable for the small-size passenger car.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a pure electric integrated power assembly for a small passenger vehicle. Background technique [0002] In the 21st century, the Chinese government has put forward an industrial development policy to encourage the development of small-displacement energy-saving vehicles, and pure electric vehicles are an important means to achieve this goal. Because of its zero-emission characteristics, pure electric vehicles adapt to the general trend of energy-saving and environmental protection, and have an absolute advantage in the promotion of large and medium-sized cities. [0003] At present, most of the loading solutions for commercial vehicles and large and medium-sized passenger cars in the market are multi-speed transmission systems with drive motors, while small passenger cars mostly use direct-drive motor systems. During the actual driving process, the state of the ca...
