We need a front differential to maintain speed around corners and keep the wheels from sliding on the pavement. After calculating the ratio between the bevel gears that we need based on the length of the wheel base, I modeled the basic design of a "perfect" front differential for the new base.
I haven't been able to add a sprocket for the ring gear, because the sprockets I've found online do not have dimensions for the mounting holes. I ordered one so I could measure it directly.
I have the same issue with the universal (CV) joints available. They are made for specific vehicles, so the only "dimensions" available are make and model. I ordered CV axles for ATVs that I found at a deep discount so I could measure the shafts directly.
Shaft diameter may change the size of the bevel gears in the differential, which would change the overall dimensions of the differential. This is when I really appreciate Fusion 360's parametric timeline. I always start a design by laying out the purchased parts and anchoring dimensions from those parts. It makes it much easier to change parts and have the change ripple through the timeline.
