AI Technical Summary

Technical Problem

Existing hybrid power systems cannot meet the space requirements of batteries in four-wheel drive vehicles when longitudinally mounted, making layout difficult.

Method used

A longitudinally mounted front-wheel-drive hybrid transmission was designed, which directly connects the engine and the generator. The clutch is located inside the generator rotor. The generator and the drive motor are coaxial. The first gear mechanism is located at the rear end of the drive motor. The power output mechanism integrates the differential. The shifting mechanism is located at the rear end of the drive motor, realizing two-speed output from the engine and the drive motor.

Benefits of technology

The size and cost of the transmission were reduced, the integration of the front axle hybrid system was improved, more space was reserved for battery design in the whole vehicle, and range-extending power generation, front axle drive and kinetic energy recovery functions were realized. The torque requirements of the engine and drive motor were reduced, and the fuel economy and energy efficiency of the whole vehicle were improved.
