CONTI® UNIPOWER EXTRA HIGH PERFORMANCE XHP

Automobile manufacturers must reduce CO₂ emissions from their internal combustion engines by around one-third in the next few years. Automotive hybridization is therefore an important issue – for us, too. New technologies such as the 48 V Eco Drive system have been designed to deliver cost-efficient large-scale hybridization. Our specially developed UNIPOWER XHP high-performance multi V-belt provides the drive for the 48 V belt alternator starter and the ancillary components.

Technical Specifications

Special fabric covered surfaces (tough grip) on the rib side
High modulus aramid cord
Flexible EPDM compound, injection molded profile
Broad operating temperature range of -40°C to +140°C
Belt lengths from 800 mm to 3200 mm
Excellent service life: potential for more than 240,000 km
Excellent noise behavior
Superior abrasion resistance

Benefits & Features

Superior static and dynamic load carrying capacity
Optimized power transmission behavior
Extremely wear-resistant surface
Excellent noise behavior, even under extreme conditions
Specially designed for 48 V mild hybrid applications in FEAD
Up to a 20% reduction in fuel consumption for 48 V mild hybrid systems
Increased comfort thanks to the belt driven start-stop system
Improved performance due to torque support (boost)

Market trailblazer

Our development of the system, comprising the 48 V 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 48 V belt alternator starters consume significantly more power than the 12 V 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,” explains product manager Manfred Bonkowski. The UNIPOWER XHP is optimized for 48 V hybrid systems, enabling fuel consumption to be reduced by up to 20% while also ensuring reliable power transmission.

Able to meet future demands

Power transmission belts will continue to be faced with increasing demands – with particular reference to belt-driven mild-hybrid applications, they have to transmit ever higher torques, last for the entire service life of the car and contribute to environmental protection. “The belts have not yet reached the limits of their operational capability,” states Bonkowski with conviction. “We have already developed numerous power transmission belts that have met these growing demands and are also already working on new solutions”.
