So, this question is actually work related (which will allow me to justify checking MT at work as much as I currently do.)
are currently using 2x Linear potentiometers on the front of our cars to measure wheel travel on the road and track. They seem to be working well so far. The front suspension is a Strut style suspension and allows us plenty of room and no movement in weird directions.
The problem stems from our rear end: The string pots!
The reason that we have been using the string pots is because it allows us to more easily measure movement on solid axles and independent suspension chassis both, using the same sensor. They also move in weird directions which allows us to compensate for axle fore-aft movement/etc. It also has a very small cross section which we feel that we need with some of the IRS setups we deal with where the shocks are run very close to chassis components.
We have broken 3 string pots in the past 2 months just from setup/user error/testing. When a string pot retracts quickly into its housing it snaps off the end, winds up the encoder and breaks it. It is ALOT
easier to do then you would think.
So yeah, I broke another string pot today and so...
Do you know of a better way to measure rear wheel travel?
I'm just curious to hear if there is anything we have been missing.
Thanks for the help,
