Tyre Changer Torque Limiting for Speed-Dependent Wheel Handling

The torque limiting threshold is made dynamic rather than fixed. The controller automatically adjusts the torque threshold based on the detected rotation speed of the chuck. At high rotation speeds, a lower torque threshold applies to prevent damage, while at low rotation speeds, a higher torque threshold allows working on rigid or heavy tyres. This dynamic adaptation resolves the contradiction by making the torque limitation context-dependent.

The system changes the torque parameter threshold based on the rotation speed parameter. When rotation speed exceeds a first threshold, the torque threshold is reduced to a second (lower) value. When rotation speed is below the first threshold, the torque threshold can be the higher first value. This parameter coupling allows the system to adapt torque limitations to operating conditions, enabling both safety at high speeds and capability at low speeds.

The torque threshold is transformed from a static calibration value to a dynamic value that varies with rotation speed. The controller continuously monitors chuck rotation speed and automatically selects appropriate torque thresholds from multiple predefined thresholds. This dynamic behavior allows the system to be safe at high speeds while remaining flexible and capable at low speeds, resolving the contradiction between safety and adaptability across different operating conditions.

The operating range is segmented into multiple speed zones, each with its own torque threshold. The controller divides the rotation speed range and assigns different torque limits to different segments. This segmentation allows optimized torque delivery for each speed range, ensuring safety in high-speed segments while maintaining capability in low-speed segments, thus achieving both safety and flexibility across the full operating range.
