So, as I mentioned in that previous post on air conditioning, I was at my shade tree mechanic's yesterday; he was fixing a fuel leak on my '68 Westfalia. And he had what I'm thinking may be the best idea yet for connecting the electric motors in the Mustang.
Basically, mount a gear (two gears, in this case) between the transmission and the U-joint, mount the motors under the seats, and connect each to the gear on the driveshaft with a chain. The quick research I've done since then makes me think a motorcycle's belt drive would likely be much preferable to a chain drive. This would solve a *lot* of geometry problems, *and* it would allow some flexibility in using different gearing for the electric motors than the V8. For example, if I have the math right, with a 3:1 rear end (factory stock for this particular car that might still be in there) and standard 65- and 34-tooth pulleys, the electric motors would see a 5.7:1 ratio. They'd already be over 1000 RPM in 15 MPH school zones, but they still wouldn't reach 8000 RPM until above 100 MPH. 65 MPH would be at 5000 RPM, which is peak power for the AC-51. My biggest concern would be the sideways torque on the motor shaft. Is that a valid concern? HPEVS markets the AC-35 for use in motorcycles, and I'd think that the AC-51 shouldn't be less capable in that regard. I imagine there might be some challenge in machining something that would allow the mounting of the pulleys to the driveshaft...but I also know that there're machinists who're miracle workers who would be glad to do something like this...for a price.... So...the question I'm sure y'all're tired of hearing from me: am I crazy? Thanks again, b& -------------- next part -------------- A non-text attachment was scrubbed...
