Pedal Vehicle Power Unit With One-Way Clutch for Reverse Torque Blocking

The one-way clutch serves as a mechanical intermediary that enables the control gear to rotate in both directions for full transmission ratio control while preventing reverse torque from being transmitted to the control motor. This allows the use of a smaller, more compact control motor designed for unidirectional operation, resolving the contradiction between adaptability and motor volume.

The one-way clutch extracts or separates the bidirectional rotation requirement from the control motor's functional requirements. By placing the one-way clutch in the torque transmission path, the system removes the need for the control motor to handle reverse torque, allowing the motor to be optimized for unidirectional operation with reduced size and volume.

The one-way clutch is positioned as an intermediary component that blocks harmful reverse torque transmission from the control gear to the control motor during second rotation direction operation. This protective intermediary prevents thermal damage and excessive heating, thereby extending the control motor's operational lifespan while maintaining the ability to adjust transmission ratios across the full range.

The one-way clutch converts the potentially harmful reverse rotation into a beneficial protective action. By allowing the control gear to rotate in the second direction for transmission ratio adjustment while simultaneously blocking harmful torque transmission, the system transforms what would be a damaging condition into a safe operating mode, preserving motor reliability while maintaining adaptability.
