Design of an innovative bike brake integrated into the wheel hub

Abstract

The public urban bike services demand more robust mechanical devices to resist misuse and vandalism. An innovative wheel hub integrated bike brake was designed making use of CAD-3D and numerical analysis tools and considering both technological and economical criteria. Unlike the other existing hub integrated bike brakes, the new design ensures an homogeneous pressure distribution on the braking pads, which maximizes its lifespan, reduces the maintenance costs and guarantees an uniform performance along the brake lifespan. As the other existing hub integrated brakes, the new design is very compact, robust and low sensitive to adverse environmental conditions and dirt.
