E-drives

For reasons of cost and weight, manufacturers have so far tried to do without gearboxes in electronic drive units. However, it is now clear that an electric drive, which is characterized by a wide speed range and a reversible direction of rotation, definitely benefits from the integration of a gearbox.

An electric motor-gearbox unit has various advantages. For example, a more energy-efficient drive solution can be realized by using a central electric motor. The increase in the consumption map then has a positive effect on the range of the vehicle. Integrating a transmission is particularly worthwhile for vehicles that travel at high speeds and also require high tractive forces. This applies to light commercial vehicles, for example, but also to state-of-the-art sports cars. In any case, high-quality gearing components remain essential for durable and reliable transmissions.

At Ilmberger, manufacturing companies in the field of electric drives and vehicles find an experienced partner with many years of experience after the development phase. Our technicians and designers have a wide range of options for the individual production of high-quality transmission parts. This enables us to produce reliable, solid and durable components that also prove to be valuable and cost-efficient in large-scale production.

High torques, wider speed ranges and immediately available maximum power: electric drives perform well. This makes it all the more important to meet them with precisely manufactured components. We know the requirements placed on gears and shafts in electric drive units and implement them precisely.

Measure, analyze and optimize: This is how we support you

Our production processes are always accompanied by state-of-the-art measurement technology, both in the initial phase with prototypes and in pre-series and small series production. This means that no need for corrections is overlooked and the full optimization potential is exploited. This prepares you ideally for large-scale production, in which all necessary aspects must be implemented without compromise.

A frequent step here is tooth flank grinding. In this work step, the tooth geometry can be significantly optimized with the help of ultra-modern machines. This is important because electric motors work very quietly and any gear noise would otherwise be clearly perceptible. Electric drives with a quiet and low-vibration gearbox are therefore essential.

The grinding process takes place in the course of hard finishing, which is carried out after hardening in our in-house hardening shop. A wide range of corrections can be made here to reduce noise development and thus ensure pleasantly quiet drives with very smooth running. We also test which corrections are actually effective and look at each project individually. Achieving the maximum is a matter of course for us.
