Hi Folks,
This is my first post and it's regarding an automotive project. I am not afraid to smoke some things in the testing and construction process, as I don't have any idea how to make this work and expect some smoke along the way. Maybe All About Circuits can point me in the right direction...
I have tasked myself with a goal of creating a paddle-type shifter for a kit car. The car uses an older Porsche style transaxle - the type that uses a long rod that runs from the shifter between the seats, to the very back of the car, turns back 180 degrees and then performs in-out and right-left rotation movements. It didn't work very well.
The old rod-style has since been replaced with a cable-style, but the movements at the end are the same. It works better, but an electronic version would be the best.
So, the installation would use two, three-position, push-pull devices, with the logic to understand the correct position for the required gear selection.
I am guessing that 25-30 lbs of pull-push would be enough. Progressive force would be most appropriate to emulate human arm motion. The three positions have to be positive motion (without relying on spring return). Positions should be reasonably high repeatability, perhaps software adjustable, and probably require a range of 3" of travel.
Maybe this isn't a solenoid application? Maybe a pair of quick, strong steppers? Unfortunately, I have no knowledge of positioning devices or options here.
Thanks for any suggestions you can offer.
Regards,
