2WD idea - Page 2

 


Excessive thinking leads to disenchantment if you can never make your
fantasies become real...


Find a transmission mainshaft from a small automobile. You don't need
the countershaft at all, and the gearbox case would be rather bulky
too,

But you can use the shaft itself and one of the synchromesh units that
lock the parts of the mainshaft together for high gear to make a
"shift-on-the-fly" gearbox to drive the sidecar wheel whenever you
want to.

Another alternative would be to find planetary drive assembly from an
automatic transmission used in a small car.

In order to engage the sidecar wheel you have to apply pressure to the
band that stops the outer ring gear from turning.

 


<more thinking>... Don't automatic transmissions contain
some sort of fluid-coupled torque converter which allows
for slippage between the rotors? Maybe I could rig up
some kind of hydraulic contraption.

However I suppose with any scheme like this the wheel
with the lesser traction will be the one that spins,
so maybe direct mechanical coupling is better after all,
assuming I can disable it on dry pavement.
