you can pick up a solidworks connected for $49 a year which is everything bar solidworks motion which you probably wont need, failing that fusion 360 is free

This is how it looks like inside the axle casing...I use a #35 steel chain that wraps around both wheel axles sprocket and goes at the bottom of the center sprocket. I printed the sprockets with brass axles so i would just strip or slip when under heavy load. easy to repair than having to repair a stripped gearbox. the center sprocket is directly attached with a flange to the double output shaft geared motor, so it is all locked up, no center differential gears...
