Design of Direct Mount B-Knuckle for Bicycle Derailleur
 Chalupa, David ; Strecker, Zbyněk (referee) ; Košťál, David (advisor)
This bachelor thesis focuses on optimizing the shifting mechanism of mountain bikes by eliminating inaccuracies caused by the use of a replaceable hanger. The aim was to design, manufacture, and test an adapter enabling direct attachment of a mechanical derailleur to the mountain bike frame. The essence of the work lies in utilizing 3D printing to produce mechanically stressed components. Within the project, two adapter designs were introduced: the first optimized for production using 3D SLS printing technology with the intention of commercial sale, while the second adapter is tailored for production on home 3D printers. Both adapters were designed using generative design based on analyzed loads. The outcome of the work is two fully functional adapter solutions. Testing revealed that the adapter manufactured using SLS printing technology from PA12 material exhibited a 24.8% increase in stiffness and a 2.85% decrease in weight compared to a derailleur attached using a hanger. The adapter produced using FDM technology from ASA material achieved a stiffness increase of 127.5% and a weight reduction of 2.3%.
