The increasing requirements in energy-efficiency, lower space utilisations, performance and operating characteristics support the development of new powertrain concepts.
This leads to the development of power-split transmissions.
Next to the often applied external power-split principle, there exists also the much lesser-known internal principle. Due to its compact design there is a great potential to save installation space and weight. These benefits have an additional positive effect on the energy-efficiency and support a cost reduction.
The importance of this new drivetrain technology was confirmed at BAUMA 2016 in Munich. There the "Science Price of the Expert Panel of Construction Equipment (Münchener Kreis)" 2016 has gone to: Dr.-Ing. Marco RAMM for his dissertation:
„Systematische Entwicklung und Analyse stufenlos verstellbarer Getriebe mit innerer Leistungsverzweigung für mobile Arbeitsmaschinen“.

The Torque map (original name: “Drehmomenten Plan”) is a graphic illustration method for synthese and analysation of Powertrains. The increasing requirements in energy-efficiency, lower space utilisations, performance and operating characteristics support the development of new powertrain concepts. This leads to much more complex and dynamic powertrain systems (e.g.: power-split, power-shift, hybrid systems etc.).
Due to the complexity of new powertrain concepts the Torque map method become more important. Reasons therefore are the much better illustration clarity, the comprehensibility and the elegant calculation procedure in comparison to current methods.
KREINS Technologies is working on the further development of this methode in order to allow a user friendly application.
Due to their tribological stress, axial sliding shaft-hub connections are strongly wear-prone or require high-maintenance (circulating oil lubrication, regular replacement, etc.)
The aim of this research project is the development of a shaft-hub connection, that ensures a backlash-free torque transmission (one- or double-sided) over a long period even though an axial displacement.
