First, I need susp for bad roads, and this construction will decrease
ground clearance. That's BAD! Of course, it's possible to change
frame geometry, rising it, but this solution has it's own drawbacks.
Drawing is only to show the functionality. In reality this suspension
can be built quite neat and without increasing ground clearance. E.g.
with two rubber blocks on each side of the pivot.
Second, this thing will "bang" each time it returns in place. And I
speak not about noise, but shock stress on the hinge. How many times
goes it to live? So, we need some dampener between hinge and fron
fork, which leads us back to interference from pedaling (somewhat
decreased).
The rear suspension of the python uses the same principle and there
is no collision noticeable. The system weight holds it in a state of
equilibrium. I would give it a try in my next experiment and see how
it works in real life. Seems quite promising to me.
From side it will look like a crocodile holding rubber block between
foreteeth. :-)
Very suitable for a python :-)
However, this construction is VERY HEAVY, since both upper and lower
forks has to be very stiff (perhaps even stiffer than original single
fork).
Interesting design approach. Though here the chain pull comes into
play again. But maybe this can be improved further.
But sorry: I have no time to think about it. I have to pack my
equipment and I will start for a 1500 km python tour tomorrow
morning.
See you later listies and have a good time,
Jürgen.
