It has drawing submitted by HD for a Front Wheel Trike that leans into
coners...... Looks like it would be a fun ride.

Very interesting. But stupid.

The whole idea of putting the two wheels up front on independent a-arm
suspension is to keep the tires FLAT on the ground so you can use ALL
the width of the rubber while cornering the short wheelbase trike as
hard as a car.

 


I was behind one of these Can Am things
(http://www.motorilive.com/wp-content/uploads/2008/07/bombardier-can-am-spyder.jpg )
some weeks ago, and I watch quads every now and then.

I can see how cornering flat with wide tyres gives you nice lateral g's.
However the concept of riding on these things like on a motorbike seems
wrong to me. When cornering hard, you can see how much force the rider
has to bring up to stay in the saddle, compared to a leaning motorbike,
where the rider ideally has just to compensate for the additional
gravity and no side factor.

I think if something wants to corner flat, it should have a car seat.

Comparing the Piaggio MP3 (you start seeing more of them on the street,
colleague rides one) which is a rather relax and effortless ride.

I was considering the design of a non-leaning front engined front
wheel drive three wheeler a few years ago.

I initally thought of obtaining a Yamaha V-Max and bolting a space
frame in front of the steering head, and retaining the motorcycle seat
for an exciting passenger accomodation.

Imagine being a passenger on such a vehicle while it is cornering at 1-
g lateral...

There have been quite a few built which were essentially three-wheeled
cars with motorcycle engines, and some had cozy side-by-side passenger
accomodation.

Such designs that use a donor motorcycle, bolting the motorcycle
engine and frame to a tubular space frame up front, become rather
longish, and tend to look like a grand prix car when complete.

I spotted one such creation in a service station and stopped to look.
This particular one-off vehicle used a Honda CB350 donor motorcycle.

It had two Honda motorcycle wheels up front with two vertical forks to
act as king pins. The imaginative steering mechanism was a steel
*cable* that wrapped around the steering column multiple times and the
cable pulled the wheels instead of pushing them in the conventional
manner.

Engine location determines length and weight distribution. One grand
prixesque design had the driver sitting beside the engine.

But I think the best design would have the engine up front and
probably should have front wheel drive to avoid running a long drive
shaft (or chain) through the passenger compartment.

The machine I was mentally designing would resemble a guitar pick in
plan view and would be quite low to the ground with the driver's butt
just a few inches off the
pavement.

The vehicle would be lower than, say, a Triumph Spitfire. When driving
a Spit, you could look up under the fenders of American cars at
stoplights...

I figured that the three wheeler would need a flag on a whip like a
dune buggy so other motorists would notice the motion, even though
they couldn't see it.

But I got stuck on figuring out how to design a stylish roll cage that
would allow the driver to see where he was going, but prevent him from
being decapitated by running underneath a truck...
