Electric drive system for vehicle with multiple motors
The patent US12030378B2 describes a drive system designed for vehicles, featuring a configuration that utilizes multiple electric drive motors to enhance performance and efficiency. The system includes a first electric drive motor that powers both the first and second wheels through a differential, which splits the drive into two distinct paths. This setup incorporates a second electric drive motor along the first drive path to specifically drive the first wheel, and a third electric drive motor along the second drive path to drive the second wheel. Notably, all three motors are capable of delivering power up to the vehicle's maximum speed, ensuring optimal performance across the full speed range.
Additionally, the drive system is characterized by its lack of disengagement mechanisms for the electric motors, which means that the motors remain engaged with their respective drive components at all times. The differential allows for independent wheel rotation speeds, accommodating various driving conditions. The design also includes an input drive shaft and two axle half-shafts that connect the motors to the wheels, facilitating efficient power transfer. The vehicle can be configured with either front or rear wheels and is applicable to both electric and hybrid vehicles, highlighting its versatility in modern automotive engineering.
