[ausev] Motorcycle project, rear differential.

[Charlesvsi at aol.com]

It seems to me that 2 electric motors would handle the task better than a  
differential. I found a web site in Italy that had controllers  motors, etc  at 
it. II'l check and see if I can find it again. Cars with 2 or 4 electric  
motors have controllers with software that senses the drag on the motors and  
shifts power to the one that needs it. electrically its easy to sense this and  
change the voltage or phase shift.

Chris,
THANKS!   That's the place.
I just got  back from the BMW motorcyle dealership and also the Woods Fun
Center on  Braker/IH35.
The BMW dealer was really really interested in my  plan.
He said while an offset of cost against a new motorcycle with engine,  etc
resale could work, it would be far better to spend a lot less on a good  used
motorcycle.
The differentials on the various ATV's at Woods  did not look like they
would be robust enough.  Although I did like  the idea of an integral disc
brake rotor on one design in particular,  (another had an integral drum brake
assembly),  the idea of a simple  pinion and spider gearset was not
appealing, even though the rear track is  to be less than 34 inches with
fiberglass body.
Erik mentioned a golf  cart differential.
How about a golf cart scrapyard?   It looks  like the final drive needs to
be the first point of the decision making  process for this first one. It
does make more sense that a golf cart load  capactiy as well as the
acceleration inertial loads would be handled very  nicely with Erik's
suggestion of a golf-cart rear axle. I need to go see  one  somewhere.

Dan.
