Precision bearings and automotive engine components manufacturer Schaeffler has announced its new hybrid demonstration vehicle, the Schaeffler Hybrid.

Based on the Vauxhall Corsa, this fully operational hybrid vehicle is part of an advanced development project at Schaeffler that enables practical comparisons to be made of a number of different vehicle configurations and driving conditions.

As well as using a conventional volume-manufactured combustion engine, the Schaeffler Hybrid also incorporates a central electric motor and two wheel hub motors.

The vehicle incorporates every Schaeffler brand, including INA, FAG, LuK, IDAM and AFT.

Dr Peter Gutzmer, member of the executive management board responsible for technical development at Schaeffler, said: ‘Being able to demonstrate and compare the various concepts of conventional and electric or hybrid vehicles, as well as realistic testing, played a decisive role in implementing the Schaeffler Hybrid.

‘Each of the various elements can be switched on or off to simulate a wide range of different driving conditions.

‘These options range from classic operation using a combustion engine, through to parallel hybrid or serial hybrid operation, or on an electric motor-only basis,’ he added.

The combustion engine can power the vehicle and be coupled for use as a range extender.

An automated manual transmission increases the options available.

The transmission incorporates Schaeffler’s LuK clutch products, which are specifically matched to the requirements of hybrid vehicles.

The energy store, which is a 16kWh lithium-ion battery (400V, 400A), is charged using energy recovery methods, via a range extender and an external power supply (plug-in hybrid).

The vehicle’s central unit is connected to the automated manual transmission using a toothed chain that drives the front wheels.

This unit comprises a liquid-cooled, 50kW, 95Nm electric motor, which was designed and manufactured by IDAM (INA Drives and Mechatronics).

The wheel hub motors were also developed by Schaeffler.

The motors mounted in the vehicle have an output of around 50kW each and a torque output of approximately 530Nm.

During the design and manufacture of these high-performance components, Schaeffler was able to draw on its in-house expertise in wheel bearings and direct-drive technologies.

The wheel hub motors each form a compact unit that integrates a wheel bearing, drive and brake.

The advantage of these drive units is the fact that they can be integrated in an existing vehicle platform without making any major changes to the vehicle architecture and offer low noise levels.

Along with the components shown in the Schaeffler Hybrid, Schaeffler’s range of products tailored to the needs of hybrid vehicles and electric mobility includes hybrid clutches (used in high-end hybrid SUVs), electromechanical chassis and steering components, as well as various differentials including a lightweight, space-saving differential with face spline and electric differentials.
