AI Technical Summary

Technical Problem

When disassembling the existing flywheel, the hub and crankshaft bolt holes are not aligned, making it impossible to disassemble using ordinary tools, which affects maintenance and repair efficiency.

Method used

Design a flywheel structure in which a torsional vibration damper and a hub are fixed to the main flywheel mass body by a two-part retaining plate. The axial fixed connection can be released by removing the retaining element. The inner retaining plate, together with the torsional vibration damper and the hub, can be removed from the main flywheel mass body and the outer retaining plate to achieve alignment of the hub with the bolt holes.

Benefits of technology

This design enables automatic alignment of the hub and bolt holes after the torque limiting device is triggered, simplifying the flywheel disassembly process and improving the convenience of maintenance and repair.
