Title: The Innovations of Karl Grad
Introduction
Karl Grad is a notable inventor based in Ruderting, Germany. He has made significant contributions to the field of mechanical engineering, particularly in the area of transmission technology. With a total of 5 patents to his name, Grad has demonstrated a commitment to innovation and excellence in his work.
Latest Patents
Among his latest patents is a gear unit for a compound transmission. This innovative gear unit features a planetary stage that couples an input and an output shaft, allowing for different transmission ratios. The design includes a sun gear, a ring gear, and planet gears that are rotatably supported at a planet carrier. The planet gears are uniquely designed with two different toothings arranged axially offset with respect to the axis of rotation. This configuration enables meshing engagement with both a first sun gear and/or a first ring gear via the first toothing, while the second toothing allows for meshing with a second sun gear and/or a second ring gear. Additionally, one component of the planetary stage is fixed with respect to rotation to the input shaft, while the remaining components can be coupled with the output shaft.
Another significant patent of Grad's is a continuously variable transmission device that incorporates a power split within a sum planetary transmission. This device allows for continuous variation of the gear ratio by connecting a second shaft of the sum planetary transmission with an electric machine, which can be coupled with an electric energy source. This innovative approach enhances the efficiency and functionality of transmission systems.
