I was dealing with one of engine manufacturer and one thing led to another. The manufacturer asked me about bell housing requirement of the engine, which led me to the transmission of the agricultural forklifts. It was not much hard to figure out from transmission manufacturer's site about bell housing requirement. ( JCB - SS640)
Out of curiosity I started getting much into transmission. Couple of things I don't understand about transmission are :
1) How different is Power shift transmission (JCB-PS750) vs Synchromesh Powershuttle transmission(JCB- SS640)? Not just in cabin for
operator, but how its differently built and function?
2) Why transmission manufacturers keep adding more and more speed into gear. I know that driving in last gear is always fuel efficient,
but how its helpful adding more speeds. 4 speed forward vs 6 speed forward, How different it would be in performance?
