Re: Engaging Gears Perpendicular to Shaft Direction?
I like the simplicity, and the method on keeping both the different output shafts powered at all times. Only thing I would worry about with those two sprocket sets is keeping the chain tensioned properly. I would also be sure to put a nice little disclaimer for teams in the white paper about some things to watch for and possible breaking points so they could buy spair parts to ensure they will always move.
[edit] Thinking about this shifter a little more, I see some big advantages to possibly 2nd or 3rd year teams out there. Since all this idea is, is a simple 3:1 and 1:1 shifter, teams who were planning on doing a 2 motor, or even possibly a 3 motor gearbox per side can still use that gearbox, run chain from it into the shifter, and then from the shifter to the wheels. The way the design is given leaves all the math entirely open so teams still have to do a majority of the work on thier own. If anything teams can use this as a learning tool in the off-season to make a combiner gearbox and run it into the shifter, and then in the real season they could incorporate the two together and add to the design. Very flexible in the area of speeds too as long as you the rough calculations. [/edit]
