Sorry for the delay, and thanks. I’ve been reflecting over the question, not ignoring it. Hydraulic drives have much to offer and could be in the future, but there are many design obstacles to overcome for dezert racing. In every sense of the word, this race car has a transaxle. I can only get into some of what makes it work, some of what it can do, and some of what it doesn’t have. IMHO, a transaxle can be the ‘seed crystal’ to the design of the entire rest of the car.Are you using the trans to power hydraulics for the rear so called axle.
Just a guess, I think I read somewhere that your trans was putting out alot of pressure. Plus that would explain why theres not a shifter.
I have seen something similar on a street sweeper. It connects directly to the ring and pinion. I have thought about this for a rock crawler to eliminate driveshafts, but didn't think I could get the speed needed.
Enjoyed the read.
