Abstract

The invention relates to a blade electric vehicle integrated two-shift automatic electric drive assembly, the assembly is suitable for a front-engine front-drive automobile or a rear-engine rear-drive automobile and comprises a drive motor (E) and a dry clutch two-shift automatic transmission (T); the dry clutch two-shift automatic transmission (T) is arranged on the output end of the drive motor (E); the drive motor (E) is a DC drive motor or an AC drive motor and comprises a drive motor rotor (10), a drive motor stator (11), a drive motor box (12), a first bearing (13) and a second bearing (14); the dry clutch two-shift automatic transmission (T) is a double-shaft structure and comprises an input shaft assembly (I), a middle shaft assembly (M), an outlet assembly (O) and a box assembly (0); the assembly provided by the invention adopts a fixed axis gear transmission scheme, the transmission efficiency is high, the structure is simple, the transmission ratio is easy to match, and the production cost is relatively low.

Description

technical field [0001] This project involves a pure electric vehicle integrated two-speed automatic electric drive assembly, which belongs to the field of automobile technology. Background technique [0002] With the increasingly severe environmental problems and the depletion of traditional fossil energy, the industry wave of developing pure electric vehicles has been set off worldwide. In my country's "Thirteenth Five-Year Plan", the construction of "Industry 4.0", and the realization of "Made in China 2025" and other national strategic plans, it is clear that pure electric vehicles are the main strategic orientation for the development of new energy vehicles and the transformation of the automobile industry in my country. [0003] Electric drive assembly technology is the core technology of pure electric vehicles, which directly determines the power and economy of vehicles. At present, pure electric vehicles on the market are mainly matched with single-speed reducers. Al...
