ContiTech shows oil-tolerant car timing belt

ERJ staff report (BC)

Hanover, Germany – At the IAA (Frankfurt) motor show, ContiTech is demonstrating a new engine timing belt adapted for an oily environment in terms of elastomer, fabric and cord configuration.

The belt uses polyamide/aramid fabric with a Duralon coating containing Teflon, a rubber compound made from ACN-HNBR (hydrogenated acrylonitrile butadiene rubber) for which “ultra-durability” is claimed, E-glass and K-glass.

As well as maximising length stability, ContiTech’s aim is to reduce camshaft drive belts for the next generation of car engines from the current 16-20mm width to as little as 10mm.

Ralf Berger, head of key account management and application engineering at the ContiTech Power Transmission Group said that timing belts are already in use for oil pump and timing drives in the newer Ford, PSA, and Volkswagen engines.
