is focusing on electric mobility. The company is demonstrating this by
simultaneously launching several new electric axle drives (electric axles).
axles are a key element of our electric mobility strategy,” says Matthias Zink,
CEO Automotive Technologies at Schaeffler AG. Until now, up to three drive
components were assembled in one compact unit. With the so-called 4in1 electric
axle, Schaeffler is now going one step further by integrating the thermal
management system as well as the electric motor, power electronics, and
transmission into the axle drive. This makes the axle drive more compact and
lighter and ensures greater comfort.
particularly efficient thermal management system also ensures that a car
travels further on one battery charge and charges faster. Another new
development are electric beam axles for pick-up trucks. In the future,
Schaeffler will supply beam axles to automobile manufacturers, particularly in
Efficiency factor thermal management
is a scarce and valuable resource in electric cars. They do not have the waste
heat from internal combustion engines for heating the interior, for
example. Furthermore, particularly at
high and low outside temperatures, the range and rapid charging capability
essentially depend on whether, for example, the battery can be held in a
suitable temperature window.
thermal management system has a significant influence on the efficiency and
comfort of the vehicle,” says Dr. Jochen Schröder, head of the E-Mobility
business division at Schaeffler. The company therefore already offers thermal
management systems for all types of vehicle powertrains and is continuing to
develop them. A new approach is the combination of the drive components of a
conventional electric axlewith the thermal management system, which was an
independent module in most cases until now.
creates a highly integrated and compact complete system, which requires
significantly less space than non-integrated solutions,” says Schröder.
Furthermore, less energy is lost in the form of heat because unnecessary hoses
and cables can be dispensed with. “In addition to the compact design, the
greatest advantage of the 4in1 system is the optimized interaction of the
individual subsystems,” says Schröder.
is because Schaeffler’s experts always consider the thermal behavior of
individual drive components such as the electric motor or the power electronics
as well as the most efficient and comprehensive thermal management of the
entire vehicle. For example, an intelligent control system ensures that excess
heat is efficiently dissipated from the power electronics and electric motor
and that it is used in the interior of the vehicle. The temperature of the
battery is also regulated in such a way that the car can travel further on one
battery charge and that it charges faster.
supplier realizes further efficiency benefits by bringing in a new heat pump,
which is operated with the natural refrigerant, carbon dioxide. Not only does
carbon dioxide have less impact on the environment than conventional
refrigerant, it also has physical characteristics, which allow more efficient
heating and cooling of vehicles. “By means of our 4in1 electric axle with an
integrated thermal management system, we can achieve an even higher efficiency
level of the complete system,” says Schröder. An efficiency level of up to 96
percent is possible in an optimally designed system. Each additional percentage
point translates into an increased range.
drives – from the individual component to the complete system
its 4in1 electric axle, Schaeffler is developing its most comprehensive drive
system for electric cars so far. “Such highly integrated complete systems are
attractive for both established automobile manufacturers and new players,” says
Schröder. This allows a reduction in the development time and the costs for the
complex new development of the entire drive. Nevertheless, the company will
continue to offer to its customers individual components and subsystems for
electric and hybrid drives such as electric motors, transmissions, bearings,
and the thermal management system.
range also includes the combination of two or three drive components.
Schaeffler is therefore opening up a particularly large market, especially
since in the future electric axles will be used in vehicles ranging from
passenger cars through to light commercial vehicles – with purely electric
drives and drives based on fuel cells. This would extend also to tailored
electric axles and components for the electrification of commercial vehicles
and heavy-duty applications.
the electrification of medium-duty pick-up trucks, particularly for the North
American market, Schaeffler is developing and will manufacture an electric beam
axle. In the electric beam axle, the electric motor, transmission, power
electronics, and the entire rear axle are connected to each other and supplied
to the customer as a ready-to-fit unit. Axles like these are more than two
meters wide. Schaeffler has already secured its first orders for electric beam
axles from automobile manufacturers. The company is therefore entering a new
market segment for electric axle drives.
Global production network
manufactures components for electric axles at several locations worldwide. In
September 2021, production started at its plant in Szombathely, Hungary. This
production location is the Schaeffler Group’s first pure e-mobility plant and
its new competence center for the manufacture of components and systems for
electrified powertrains. In addition, components for e-mobility and integrated
electric axle drives are manufactured in Taicang, China. A further production
facility is being set up in Wooster, US, where hybrid modules are already being
manufactured. And the new global lead plant for electric motors is now being
built in Bühl, headquarters of Schaeffler’s Automotive Technologies
company plays to its special strengths in the production of electric axles:
Schaeffler is well versed in the production of individual components through to
high-precision manufacturing methods such as stamping individual stator
laminations for electric motors and the winding ofrotors using innovative wave
winding, for example. By using them, improvements can be achieved at the level
of individual components, which together result in a more efficient complete
system. In addition, the company is using its high level of production
excellence to bring electric drives on to the market quickly in high volumes.
