Title: The Innovations of Stefan Groetzinger
Introduction
Stefan Groetzinger is a notable inventor based in Gehrden, Germany. He has made significant contributions to the field of automated transmission technology. With a total of 3 patents, his work showcases a blend of creativity and technical expertise.
Latest Patents
One of Groetzinger's latest patents is a sensor arrangement for an automated transmission and method for detecting a magnetic interference field. This innovative sensor arrangement includes multiple axially parallel shift rails that are axially displaceable by associated shift actuators. The arrangement features multiple displacement sensors composed of a signal transmitter attached to a shift rail and a signal receiver fixedly arranged on a housing. The signal transmitters are designed as permanent magnets, while the signal receivers utilize 3D Hall sensor technology. This invention aims to detect external magnetic interference fields that could corrupt sensor signals from the displacement sensors.
Another significant patent is a device and method for sensing the position of a shift fork of a transmission. In this device, the shift fork is connected to a piston rod of a shifting piston, which is guided axially in a shifting cylinder. The shift fork engages an axially slidable sliding sleeve that slides on a transmission shaft to engage or disengage a transmission stage. A magnet serves as a signal generator, and a 3D Hall sensor, positioned relative to the magnet, detects the magnetic field generated by it. An electronic control unit connected to the 3D Hall sensor determines the position of the shift fork and transmits this information as a signal.
