Re: pic: 35 MPH Prototype
I calculated the theoretical top speed using the rpm and gear ratios in the transmissions. The big black tank is for the pneumatics to change gears. The tank is so big that we only filled it once for all the time we were playing with it. We didn't officially clock it at 35 MPH, but we were guestimating. And as for the caster in front, at the beginning it was centered. That thing bounced around so much I couldn't control it. But it was FUN!
The gear ratio in the transmission is 4.17:1 which is about 1247 rpm. Then it goes 1:1 from the transmission to the 12" wheel.
