Summary

In the long term, the number of drive solutions in the field of electric mobility will decrease compared to combustion engines and hybrids, with the electric axle playing a special role in the integration of functions. Friction systems for torque management to stabilise, agility and emotionalise vehicles will play an important role. New technologies and innovative approaches are needed to meet performance and comfort (noise, vibration, harshness) requirements. The characteristics of the power output of electric motors and the ambient media, which place a large number of new demands on neighbouring components such as the power electronics of pulse inverters and the cooling of winding heads, pose particular challenges for the friction systems in an electric axle. The components of the e-axis also play a key role in increasing efficiency/range. Decoupling units are used to engage or disengage a drive axle or individual wheels. Using new, even more resource-efficient processes, sintering technology offers solutions for high-strength assemblies combined with the lowest possible CO2 footprint during production.
