AI Technical Summary
Existing torque dampers use rivet connections, have a large number of parts, and cannot achieve lightweight design.
It adopts a flexible disc, flywheel, washer and driven disc structure, and connects friction plates through a fitting structure, reducing the number of parts and realizing a fitting design that does not require connecting plates and rivets.
This effectively reduces the number of parts in the torque damper, improves its lightweight design, simplifies the assembly process, and increases production efficiency.
