„The electrification of the drive strand is not for ZF end in itself “, like that Dr. Peter Ottenbruch, Technik-Vorstand of the ZF Friedrichshafen AG. „A substantial goal is it to lower the direct and indirect consumption of fossil fuels and to minimize thus the output from CO2 to. To this objective ZF aligns its development strategy regarding electric drives. “ Hybrid component system A substantial element is the ZF-Hybridbaukasten: On the basis of hybridable basic gears individual hybrid solutions in different development can be realized. The assigned hybrid devices come from the ZF-Produktportfolio: A nuclear component is the electrical machine DynaStart. Depending upon hybrid performance class it is available with different achievement. For applications of full hybrid ZF DynaStart is available also as hybrid module with integrated separation clutch - a technical precondition for purely electrical driving. So that a hybrid drive functions, is besides an efficient hybrid management importantly.
This is necessarily for a perfect interaction of the internally developed hybrid hardware with control electronics, software and power electronics and belonged likewise to the ZF-authority. System authority The fact that ZF supplies all components for hybridizing from a hand facilitates the integration to an cost-efficient overall system. Owing to its versatility can be represented for example mild, full and Plug in Hybridlösungen with a high equation hurry portion and large synergies.
ZF-Hybridgetriebe left the development stage long behind itself - they are used already today in series vehicles: for example in BMW the Active hybrid 7 and in the hybrid variant of the AUDI Q5. As full hybrid versions they reach consumption and emission savings up to 25 per cent. Integrated power electronics The power electronics as central connection between electrical machine and energy storage is so far accommodated depending upon manufacturer at different places in the vehicle. On basis its 8-Gang-Vollhybridgetriebes develops ZF from there a power electronics unit, which can be accommodated build-spaceneutrally at the transmission. A condition for this is a reduction of all components and due to the high transmission temperatures a modified cooling concept. The direct cultivation of the power electronics to the transmission has several advantages: The spatial proximity to the electrical machine reduces on the one hand the system interfaces and the wiring expenditure. On the other hand exists platform-spreading pre-assembly of the power electronics for ZF the possibility for manufacturer and. The vehicle manufacturers can block the hybrid transmission model-independently then - the power electronics is always equivalent also on board. Since the again developed power electronics unit is of the plug-in type to the transmission blindly from downside, at the same time the Servicefreundlichkeit rises.
Purely electric drives A further element of the ZF-strategy is special the development of pure electric drives for the short-distance and city center traffic. Half of all trips with the car is more briefly than six kilometers - a distance, which can be mastered already today well with electric vehicles. For vehicles up to the middle class ZF with the development shows one central on the axle of sitting electric drive, how an electric car can be realized in the future with very good driving dynamics characteristics and larger range. The system consists of electric motor, a compact, in-usual translation unit, power electronics as well as steering wheel often commodity. Owing to the two-stage transmission and the innovative high speed concept high achievements with reduced material employment can be realized. The drive unfolds already when starting a torque of 1.400 Newtonmeters at the axle. Thus acceleration takes place from 0 to 100 km/h in sporty nine seconds. In the maximum are available 90 KW at the axle. eTB: Electric twist Beam - torsion beam trailing arm axle and I/O impulse in system unit A concept for small cars and Microcars pursues ZF with a new overall system from axle and I/O impulse under the name Electric twist Beam. Here the electric drive is integrated into a torsion beam trailing arm axle, at the left and right rear wheel is accommodated space-saving per a transmission/electric motor unit. Advantage of this electrical rear-wheel drive with an output of 60 KW: Its skillful and compact integration releases this in the middle of vehicle building area, creates for the manufacturers freedoms during the vehicle organization. In addition the driving dynamics and driving safety can be improved by a purposeful torque distribution. The weight-saving high speed concept is taken over under use of all synergies from the central E-final drive. The integrated arrangement keeps additionally the effects the ungefederten masses small. The points of body tying up of the axle are thereby the same as with conventional vehicles, make the integration simple into existing model platforms. Brakes and rims can be likewise taken over by series vehicles with combustion engine
