Our current design is just a number beaten into a metal plate who is attached to a one time use clamp. The clamp damages the axle and the metal plate gets beaten up until it is unreadable.
So we think the solution is a rubber protected clamp with a holder for a chip or the chip just glued onto the clamp.
We thought about rubber bands that you just glue together around the axle and cut every time the axle comes in for a revisjon. But -30 degrees, ice and 1 000 000 km+ runtime before it comes back in might make rubberbands an unreliable solution. Thoughts?
I started looking at normal Hose clamps but most would be unsuitable as they would not have the required bolt locking against vibrations.
My first sketch is a rubberised sheetmetal solution where the chip is glued or inside a small box with a lid that is spot welded onto the thin steel band. The yellow ball near center is the CoG. Because it might need to be at least somewhat balanced too.
The ideal solution would be something over the counter we could modify. the axels will be in the region of Ø150 to Ø200mm
Edit: More precise description of the rubber band.
