Step 12Wheels, shock absorbing system
The wheels are attached each by only two big loose axes to the vertical sides of the boats. The holes in the sides of the boat are re-inforced by steel plates as the sides ae only 9mm plywood. The holes are as close as possible to the horizontal main frame, but not too close, just enough so you are able to screw-unscrew the big-ears-bolts from the inside of the boat.
But now, let's look at it closer : the wheels are not vertical to the road, they are at about 5° to the sides :
1 - this provide stability, the gravity center of the boat is much hiher than the contact to the floor, stability is necessary. Handycaped wheeling chairs use this system as well. The only defect to this system is that no rubbze wheel exist with a smooth band out of the center but slightly on the side, so you have to make sure you buy all-smooth tyre, or make sure you invert your tyres sometimes.
2 - THE FABULOUS LATERAL AMAZING SHOCK ABSORBTION SYSTEM !!!!!!!!!! TATATATANNN !!!!
Traditional suspension systems are aligned in the direction of the road, this one is lateral, and incredibly cheap, fast and adjustable ! Yes, it's realy fantastic, it really works ! The conditions : have loose fixed axes at the top, so the wheel entire fork can bend inside the axes. The rope (red) is a nylon rope, a thin one (50kg), that passes many many time from a wheel to the other wheel on the other side. The longer and looser the rope is, the more flexible !
