ContiTech Press Releases

Hanover, November 2011Belt pulleys absorb vibrations from the crankshaft • Regular replacement ensures that the drive system stays intact • Optimized in line with ContiTech drive belts

The ContiTech Power Transmission Group has further optimized its product range in line with the needs of workshops. The drive systems specialist is now offering torsional vibration dampers as single pulleys for the automotive spare parts market. The belt pulleys absorb vibrations in the belt drive and are optimized in line with the drive belts from ContiTech.

The ContiTech Power Transmission Group now also offers torsional vibration dampers and torsional vibration damper isolators for the automotive spare parts market.

New to the portfolio are torsional vibrational dampers (TVD) and torsional vibration damper isolators (TVDi). These fulfill ContiTech’s recognized OE-standard. “The new products ensure that workshops benefit from the reliability and quality of the ContiTech brand”, says Markus Pirsch, head of Marketing Service in the ContiTech Power Transmission Group. Buyers also benefit from the comprehensive service and the precise correlation with the company’s range of V-ribbed belts.

Torsional vibration dampers perform a key function in drive systems by damping vibrations from the crankshaft, thereby protecting drive belts and assemblies. With torsional vibration damper isolators, the belt drive of the auxiliary assemblies is also decoupled. If the TVD fails, the resonant vibrations caused by rotational irregularities of the crankshaft are no longer absorbed and can damage both the belt and the driven auxiliary assemblies. “During servicing, workshops should inspect the belt pulleys for cracks, distortion and corrosion”, recommends Markus Pirsch. “The damage might not always be evident, but since it very much impairs the proper functioning of the engine, operators are advised to replace the belt pulleys every 120,000 km."
