Silence the Ride: Advanced NVH Rubber Solutions for Electric Vehicles

IntroductionElectric Vehicles are quiet—too quiet. Without the masking noise of an internal combustion engine, every squeak, rattle, and road vibration becomes amplified. This has elevated NVH (Noise, Vibration, and Harshness) engineering to a top priority for OEMs.

Furthermore, EVs are significantly heavier than gas cars due to the battery pack, placing immense stress on chassis components. This requires a new generation of heavy-duty, high-damping rubber parts.

1. The "Heavy Weight" Problem

An EV battery can add 500kg to a vehicle. Standard rubber bushings used in gas cars will wear out prematurely under this load.

• The Solution: We formulate High-Performance Natural Rubber (NR) compounds with reinforced fillers to increase load-bearing capacity without sacrificing elasticity.

2. Damping the "High Frequency" Whine

Electric motors produce high-frequency vibrations that differ from the low rumble of an engine.

• Motor Mounts: We design complex, fluid-filled (hydraulic) or dual-durometer rubber mounts specifically tuned to absorb these specific motor frequencies, preventing them from transferring to the cabin.

3. Custom Suspension Bushings

The control arm bushings are the critical link between the road and the driver. Fuqiang’s precision vulcanization process ensures the rubber bonds perfectly to the metal sleeve, preventing separation even under the high torque of electric acceleration.

4. Conclusion

Achieving a luxury driving experience in an EV requires mastering the chemistry of silence. Fuqiang’s NVH engineers work directly with Tier 1 chassis suppliers to develop rubber formulations that dampen noise and survive the weight of the electric era.

5. About Fuqiang

Beyond wiring, Fuqiang produces millions of automotive rubber bonded parts, including suspension bushings, motor mounts, and exhaust hangers.

FAQ

• Q: Why do EVs need different tires and bushings?

• A: Due to the instant torque and higher weight, standard rubber parts wear out 30% faster on EVs if not reinforced.
