Precision Arc Spring Manufacturer for Dual Mass Flywheels (DMF)

As a trusted leader in automotive spring technology, we engineer custom Clutch Arc Springs that set the industry standard for durability and damping efficiency. Our solutions are specifically designed to handle the critical demands of modern Dual Mass Flywheel systems, ensuring superior noise reduction and extended gearbox life. Partner with us for high-performance arc springs that deliver maximum torque comfort and reliability.

Arc Spring for Eliminate Torsional Vibration
and Optimize Clutch & Transmission Performance.

DMF Damper Spring System

The automotive flywheel torsional damper spring set including two outer springs, 4 inner springs, and 2 slides.

Made with quenched high carbon steel, the multi-stage arc spring system has successfully undergone a 100,000-kilometer operational test on a actual vehicle.

The DMF repair/replacement spring set can resolve the issue of dual massflywheel noise (or flywheel chatter).

Improve Your DMF System

This solution uses a multi-stage, curved damping system to significantly decouple engine vibrations from the driveline.

Enhanced Performance: Smoother power transfer and optimized torque management.
Reduced Noise (NVH): Virtually eliminates gear rattle and driveline harshness for a whisper-quiet cabin.
Superior Comfort: Enjoy effortless, smoother gear shifts and a vibration-free driving experience across all RPMs.

Support and Friction Damping

To ensure stable torque transfer, the arc spring needs proper support, usually an arcuate channel (sliding shell) or radially contoured support plates.

They prevent spring buckling and generate a beneficial friction hysteresis in the torque–angle curve.

This controlled friction provides a damping effect that effectively minimizes vibration and noise within the systeT

Applications of curved springs: Automotive flywheels

Arc springs are predominantly used in:

Dual-mass flywheels (DMF) of internal combustion engines
Transmission systems requiring torque smoothing
Vibration damping mechanisms in drivetrains
Hybrid powertrains for noise and vibration reduction

Their ability to combine energy storage and damping in a compact form makes them an indispensable element in modern powertrain design.
