Electric motor with dual-direction transmission and variable gear ratios
The granted patent US12044297B2 outlines a novel transmission system that incorporates multiple gears and one-way clutches to enhance functionality in both standard and regenerative braking operations. The primary configuration includes a first sun gear, a first planetary gear fixed to a ground, and a first ring gear, all of which are interconnected through a series of carrier members. The system features two sun gears and three one-way clutches, with specific orientations designed to facilitate efficient gear coupling and directional control. Notably, the transmission can operate in reverse gear and regenerative braking modes, with a coupler that can switch between configurations to optimize performance.
Additionally, the patent describes an electric motor that integrates this transmission system, featuring a stator and rotor. The alignment of the sun gears with the rotor shaft is emphasized, ensuring seamless operation. The design allows for an output shaft on the second carrier member, enhancing the motor's utility. The claims also detail the operational dynamics of the transmission in various gears, including the engagement and disengagement of one-way clutches, which play a critical role in managing torque and rotational direction. Overall, the patent presents a comprehensive approach to improving transmission efficiency and versatility in electric motor applications.
