Elastic multi V-belts enable the non-positive power transmission of torque in belt drives without a tensioning pulley. This is because the elastic tension member enables them to maintain their tension throughout their lifetime. They drive, for example, the alternator, fan, water pump, air-conditioning compressor and power steering in modern engines.
ContiTech’s Multi-V Belt is made up of three main components: cover coat, tension member and rib coating. The cover coat with its textured reverse consists of synthetic rubber which is especially wear-resistant. The key component of ContiTech’s elastic multi V-belt is the tension member. Unlike normal multi V-belts, it is made of elastic polyamide fibers and guarantees that the belt runs neutrally.
Multi V-belts are directly subject to constant movements and various ambient influences such as dust, dirt and large temperature differentials in the engine compartment This results in aging and wear. ContiTech therefore recommends changing the belt at the latest after it has run for 120,000 kilometers. It is important to note, that it is essential during service and repair work on a vehicle with a factory-fitted elastic belt to ensure that this component is replaced with another elastic belt. Normal multi V-belts do not work in these vehicles because of their different construction.
