The ideal limit the use of modern motor fuel

Reducing fuel consumption and emissions

 increasing comfort and driving dynamics: hybrid drives 

play a big role in these development goals. delicate hybrid drives with forty-eight V technology meet these demands at a relatively low value. a decent example is that the “Schaeffler High-Performance forty-eight Volt” thought a vehicle with a Schaeffler electrical rear shaft that assists the interior combustion engine driving the front shaft. Schaeffler conjointly has innovative solutions for strictly electrical drive ideas, like the supplier’s wheel hub drive, to demonstrate the chances of an entire design the bodywork and interior.

Hybrid technology is a vital building block in coming up with a lot of economical combustion engines. The powerful forty-eight V delicate hybridisation could be a trailblazer in hybridisation because it is a lot of economical than plug-in hybrids with high voltage technology. the placement of the electrical motor contains a major influence on the practicality and performance of forty-eight potential unit hybrids. Their square measure a complete of 5 totally different installation positions, called P0 to P4.

Until now, the dominant arrangement has been the P0 during which the electrical motor is found in an exceedingly standard belt drive. Schaeffler has conjointly developed P2 architectures victimization forty-eight V technology. during this style, the electrical motor is found between the interior combustion engine and also the transmission. this permits driving modes, like recovery, electrical sailing and moving off, to use solely wattage and not have interaction the interior combustion engine.

During the North Yankee International motor vehicle Show, Schaeffler is additionally presenting the “Schaeffler High-Performance forty-eight Volt” thought vehicle. “This technology closes the gap between normal forty-eight V P0 systems and high voltage hybrid drives,” says Jeff Hemphill, Chief Technology Officer for Schaeffler Americas.

In Schaeffler’s new forty-eight potential unit demonstrator vehicle, an electrical rear shaft supplements the front shaft drive that includes a standard combustion engine and belt-driven forty-eight potential unit starter generator. The arrangement could be a fully new combination of the traditional P0 topology and an electrical shaft in an exceedingly P4 arrangement. the electric motor and also the associated power physics square measure integrated into one unit on the rear shaft. Twenty kilowatts of strict wattage is therefore for good offered from the forty-eight potential unit shaft drive. The Schaeffler electrical shaft produces a beginning torsion of up to two,000 Nm.

The forty-eight V design permits totally different driving ways to be elect so as to scale back carbonic acid gas emissions and increase driving dynamics, like emissions-free, strictly electrical driving up to thirty-five km/h in areas wherever traffic is restricted. The vehicle also can sail at speeds of up to seventy km/h. the electrical shaft thus permits a relentless speed to be maintained. within the WLTC driving cycle, the bulk of the braking energy is recaptured

 current and hold on within the industrial battery

“Schaeffler’s technology offers vital potential to scale back consumption and emissions through native emissions-free driving and also the recovery of braking energy,” says Hemphill.

But the thought offers more: an extra feature of the integral two-speed electrical shaft is that the chance of “torque vectoring” or distributing the drive forces to specific wheels. each the lightness and safety improvements in vehicles driven by this approach. once combined with front-wheel drive, the electrical shaft effectively provides the vehicle with simple machine drive.
