Title: Innovations of Karl-Heinz Schmidt in Bicycle Technology
Introduction
Karl-Heinz Schmidt is a notable inventor based in Schweinfurt, Germany. He has made significant contributions to bicycle technology, particularly in the development of multiple speed hubs. With a total of 2 patents, Schmidt's work has enhanced the functionality and reliability of bicycle gear systems.
Latest Patents
Schmidt's latest patents include a "Multiple speed hub with coaster brake" and a "Multiple speed hub for a bicycle and like vehicle." The first patent focuses on preventing unintentional jamming of the brake through innovative pawl clutches. These clutches are strategically placed between a planetary transmission and the hub shell, allowing for limited circumferential movement of each pawl. This design ensures that the brake operates smoothly and efficiently.
The second patent describes a three-speed bicycle hub where the driver can be coupled with either the planet carrier or the ring gear of the planetary gear transmission. This is achieved through radial arms on a coupling sleeve that shifts axially to engage the desired gear. The design allows for a third, lower transmission ratio, enhancing the versatility of the bicycle's gearing system.
