I'm considering building a lightweight, low power ( 2 x 3 KW) kart-like vehicle. Gokart wheels, independent rear drive shafts, dual belt drive BL motors and dual ESCs with steering vectored "electronic diff". Each motor drive, shaft, brake and wheel bearing mounted in identical stiff, boxes/frames for screwing down on a plywood chassis.
Now the question: How about building the chassis with a flexible, transversal "tongue" on which the drive boxes are mounted? This would provide a little (pendulum) suspension movement. Not much, don't want to upset the camber, and don't want to break the plywood. but enough to add to the inherent tire "suspension/absorption".
Is that viable? I know the flexing properties of plywood is a design parameter in boat hull design, but it probably flexes less than what I intend. Fatigue cracking?
thx, mike
