Mannesmann ready for alternative drives
In addition to numerous drive-independent tube products that we supply to the automotive industry, the development and production of tube components for future-proof drives are of great importance to the product portfolio of Mannesmann Precision Tubes .
Whether hybrid, battery or hydrogen-based technology, from Mannesmann you get tailor-made, innovative solutions for driveline, safety and chassis components as well as best-practice support for your projects.
Mannesmann Innovations for E-Mobility
Mannesmann is actively shaping the transformation of the automotive industry with our own product developments for vehicles with alternative drives. Dimensions, material as well as technological properties of tubes are precisely customized to the requirements the various drive technologies impose on vehicle components.
Rotor Shafts
Rotor shafts for electrically driven vehicles are components with most advanced requirements for dimensional and geometric tolerances due to the high rotational speed.
To maximize customer benefit, we offer specially machined tubes with very tight tolerances.
Renowned carmakers source our precision steel tubes for rotor shaft applications in electrical cars already today.
Specialized materials dedicated for E-Mobility
Due to their significant vehicle weights, electric and hydrogen vehicles place special demands on drivetrain and chassis components.
Optimized materials specifically for future-proof drives are developed in cooperation with the Group’s own research institute Salzgitter Mannesmann Forschung and steel producers.
Mannesmann Innovations for Hydrogen Cars
Hydrogen can be used either with an electrical engine in combination with a fuel cell or in a hydrogen combustion engine to act as an energy alternative to today’s fuels. To carry enough hydrogen for a reasonable traveling distance it needs to be stored at high pressure levels up to 700 bar. The presence of hydrogen at high pressure load is a challenging task for materials.
Thanks to years of experience in material science and high-pressure applications, Mannesmann can offer products which fit to these needs.
Hydrogen High-Pressure Tanks
As part of the public funded program HySteelStore, Mannesmann (in cooperation with Salzgitter Mannesmann Forschung and Robert Bosch) has developed steel precision tubes, which pave the way for hydrogen storage tanks.
These tubes allow a modular storage design which can be fitted in the most efficient way in passenger vehicles. Besides, steel is offering a powerful and cost-efficient alternative to CFRP tanks which are used today.
Hydrogen High-Pressure Lines
Reliable high-pressure lines are needed to connect the hydrogen storage system with the engine. This can either be a combustion engine or a fuel cell.
With a proper material selection Mannesmann offers a sustainable and cost-efficient alternative to lines made from corrosion resistant alloys.
