The chassis patented by BMW is similar to that of the supersport S1000RR. The innovation lies in the composition of composite panels from different materials (carbon fiber, aramid and synthetic composite) that are screwed to the structure to change the resistance.
If we are able to modify the torsional and bending resistances of a chassis, we can also add parameters useful for the cycling tuning. Depending on the tires used and the type of circuit, it is ideal to have different flexibility of the chassis structure depending on the need.
In many sports frames, it is possible to intervene on some measures through adjustments or the replacement of some parts. For example the:
- adjustment of the inclination of the steering rod
- height of the pivot of the swingarm
- geometries of the rear suspension and the front axle
BMW has filed a patent that tries to solve the problem more easily
- assembled or replaced quickly
- sized differently
- built with different materials
BMW mentions carbon fiber, but the composites can also be aramid-based, ceramic, polyamide and more.
About the patent
Carbonform is an agreement between three companies from Abruzzo that aims to mass-produce carbon fibre components for the automotive industry. The network contract for the development of ‘press forming’ technologies – through the conversion to compression molding of carbon fiber parts of a production plant that previously processed metal – was signed a few days ago by ACS – Advanced Composites Solutions, Susta and U.Form….
