This can be kinda tricky to explain.....
Yourtheory would be correct, but you forgot the one-way bearings inside the clutch....
each gear gas it's own independant one-way bearing , both facing opposite directions. As the engine starts to rev-up gear ones bearing locks to the shaft and begins the acceleration process, weanwhile gear 2's one-way locks in the other direction allowing the gear to "freewheel" on the shaft not being engaged, infact that bearing never engages......
Now as the RPM's come up the 2 dspeed clutch engages gear 2 at a shaft RPM level you determine, in trn this locks gear 2 to the shaft increasing the prm's of the shaft. at this point the shaft starts spinning at higher rpm's than gear 1, so the one-way bearing disengages or unlocks and allows gear 1 to turn at lower rpm's than the shaft is turning.....
The Nitro 2 speed is quite complicated if you don't understand how the inner working parts actually do their thing, but quite simple once you understand how it works......
The nitro 2 speed would be totally mpossible if it weren't for one-way bearings......
For someone giving such a high detailed description of the complexities of a 2-speed gearbox your lack of knowledge simply amazes me.
1. Their is only and will only ever be a single one-way bearing in any 2-speed gearbox. The bearing on the second gear is a free bearing which will rotate freely in both directions.
2. A 2-speed gearbox works as follows. Gear 1 is on a one-way bearing that allows it to rotate freely in a backwards direction but locks it in forward motion. When the power is applied to the car the one-way on the first gear locks to allow the gear to drive the car. At the set RPM the clutch shoes (or finger in the old type gearbox) spread and engage the 2nd gear hub which allows it to take the car to faster speeds (keeping it simple for you). When this happens the one-way bearing in 1st gear disengages and ALLOWS that gear to rotate at the same RPM as the 2nd gear (NOT ROTATE AT A SLOWER RPM WHICH IS IMPOSSIBLE CONSIDERING BOTH GEARS ARE ATTACHED TO A SOLID BELL THAT TURNS BOTH TOGETHER).
You are correct however, a 2-speed gearbox is simple to operate if you know what you are talking about
