POLY V®: a HUTCHINSON innovation for car manufacturers
HUTCHINSON offers one of the most thorough and most reliable ranges in the world of Poly V® accessory belts available as automotive spare parts. Dimensions and number of teeth are the main criteria for selecting a belt when replacing a Poly V® belt.
The Poly V® technology is a HUTCHINSON innovation which quickly became an essential for manufacturers, the first to adopt it being Mercedes with its 190 model in the mid-80's. Silent and able to withstand the new stresses of the engine environment, the ribbed Poly V® profile fully meets manufacturers' requirements in terms of drive surface area (see diagram comparing contact surfaces) and complex kinematics. Indeed, its flexibility allows it, unlike the V-belt, to drive a number of accessories simultaneously (in a coil) such as the water pump, alternator, power-assisted steering and air-conditioning, and other options which have become commonplace on touring cars in the 90's.
Now installed by all manufacturers, the Poly V® belt has totally superseded the traditional V-belt, making Hutchinson the leading original equipment supplier.
