2-stage planetary gear boxes

Planetengetriebe 2 Stufen

The intelligent KOEPFER powertrain developments are a model for an integrated approach to the development of future drive solutions. KOEPFER Engineering GmbH combines a 2-stage planetary gear box with a special engine solution and the power electronics in a single, compact unit. In this way, automobile, trucks and utility vehicles can be equipped with modular drive solutions for electric and hybrid vehicles.

The 2-stage planetary gear box can be fitted to both automobiles and utility vehicles, on either the front or rear axle. The distinctive feature: through the combination of various engines with different battery voltages in the vehicle, KOEPFER Engineering GmbH provides its customers with solutions for an almost unlimited number of applications in the output range 80 kW to 150 kW.

The drive units have been developed on the basis of the highest level of expertise and are perfectly matched to one another. They consist of an engine, controller and transmission that deliver outstanding NVH behavior (NVH stands for noise, vibration and harshness and refers to perceptible vibration in the vehicle) in operation and allow continuous improvement between the e-engine, transmission and power electronics. KOEPFER’s many years of experience in the field of manufacturing high-precision gears for engines, transmission and all developments of the powertrain always stands the test.
