Our development of the system, comprising the 48V belt alternator starter and the high-performance multi V-belt, means we are one of the first suppliers of mild-hybrid applications in the market. “The new 48V belt alternator starters have a significantly higher power consumption than the 12V alternators. We therefore had to reinforce the multi V-belt with an aramid tension member, a fiber-loaded EPDM compound and a special textured fabric surface,” declares product manager Manfred Bonkowski. The UNIPOWER XHP is optimized for 48V hybrid systems enabling up to 20% lower fuel consumption and provides reliable power transmission.
Equal to future challenges
Power transmission belts will continue to face rising requirements – with particular reference to belt-driven mild-hybrid applications, they have to transmit ever higher torques, last for the car’s lifetime and contribute to environmental protection. “The belts have not yet reached the limits of their operational capability,” declares Bonkowski with conviction. “We have already developed numerous power transmission belts that have met the growing requirements and are also already working on new solutions.
