Hello everyone,
I've been trying to figure out how i can have two different inputs that are switchable from one to another that drive a single output. However i don't want the inputs to drive each other, and also want the mechanism to be compact in size and fairly lightweight. So how can i do this?
INFO
I have one engine that is a high speed the other source is a hand/foot powered one. I have all ready researched about different types of clutch but this will be to bulky for the application, unless a centrifugal clutch was used but that still does not solve the problem of the handles/pedals rotating when the engine is working. I have also looked at a free wheel mechanism like you find on a push bike but still can't figure out how to get this to work how i want it to. Lastly i have looked at epicyclic/planetary gears but just can't understand how it work with two inputs leaving handles/pedals in a free motion.
To say the least i have slightly confused myself, perhaps I've been over thinking the problem and there is a simple answer, but its really bugging me now so i appreciate any help you can offer.
Thanks Josh,
