Dual-Drive Electric Machine With Epicycle Gear Torque Decoupling

The patent introduces an epicycle gear set as an intermediary mechanism between the electromagnetic clutch and the load. The epicycle gear set includes a sun wheel, planet wheels, and a ring gear that work together to provide mechanical advantage and control torque distribution. This intermediary mechanism allows for smoother engagement and disengagement by distributing the torque through multiple gear contacts, thereby reducing residual rotary torque and minimizing kinetic energy loss during releasing operations

The patent utilizes the variable gear ratio characteristics of the epicycle gear set to dynamically change the torque transmission parameters. By adjusting the position and engagement state of the planet wheels relative to the sun wheel and ring gear, the system can modify the effective gear ratio during engagement and disengagement processes. This parameter change enables better control over torque transfer, reducing residual rotary torque and improving energy efficiency

The epicycle gear set serves as a mechanical intermediary that bridges the electromagnetic clutch and the load. The sun wheel, planet wheels, and ring gear create a controlled mechanical transmission path that supplements the electrical control system. This intermediary mechanism ensures more reliable and effective operation by providing mechanical advantage and reducing residual torque, thereby enhancing the overall system reliability while maintaining electrical control capability

The patent segments the torque transmission path into multiple independent components within the epicycle gear set: the sun wheel, multiple planet wheels, and the ring gear. Each component can independently handle portions of the torque load, and their coordinated operation provides smoother and more reliable engagement and disengagement. This segmentation reduces the stress on any single component and minimizes residual rotary torque, improving operational effectiveness
