Title: The Innovative Mind of Manfred Rattunde
Introduction
Manfred Rattunde, a prolific inventor based in Bad Homburg, Germany, has significantly contributed to the field of mechanical engineering with 17 patents to his name. His inventive spirit is reflected in his latest advancements in transmission technology, particularly in cone pulley systems designed for various applications including motor vehicles.
Latest Patents
Among his recent innovations, Rattunde has developed an "Infinitely Variable Cone Pulley Transmission." This invention features an axially displaceable cone pulley disc that can be adjusted hydraulically. This adjustment generates pressure forces acting on a transmission belt that rotates between the cone pulley discs, with control managed through a pressure medium via a sliding control valve. The unique aspect of this design lies in its ability to adjust tensioning through different sized pressure-chargeable surfaces, which can be throttled in relation to the outlet of the valve based on specific operational parameters.
Another significant invention is the "Cone Disc Transmission, Particularly for Motor Vehicles." This technology is characterized by fully hydraulic generation of contact pressure forces. The system allows for setting the contact pressure level using a torque sensor located on the driven shaft. This pressure medium throttle adjusts based on load and transmission ratio, highlighting Rattunde's commitment to enhancing the efficiency of vehicle transmission systems.
