Comments on Dynamic Augmented Wheel System Eight-Part Wheel
Interesting concept seems to work as prototype, but despite similarity to smartwheels, I think there is a traditional solution that works better (Read

| ""it's not clear to me why this kind of elaborate machine will do any better than a wheel with negative camber"
Get a box, and tip it to the side. Notice how the bottom comes off of the ground except for the corner? With just negative camber, that's what a tire tries to do. The rubber is pliable enough that it doesn't matter for 98% of drivers, but in a race, that loss of grip can hurt. This system gives the effect of a negative camber while keeping the full tread on the ground. It is, however, only truly useful for street-course racing. On oval courses, like those used by NASCAR and such, the car only turns one direction, so the suspension and tires can be customized for that application. My biggest questions are how fast can this thing move the segments, and how durable and reliable is the system? Cost probably won't matter to the only realistic market (Formula 1 type racing), but if it can't move fast enough to keep up with the corners, it'll still be a waste of money. Moreso if the thing breaks down 5 times per race.
"the advantage is you can then have a tire without air(no flats)"
we already have the tweel (http://www.technovelgy.com/ct/Science-Fiction-News.asp?NewsNum=309), and it doesn't require a complex, heavy, and most likely very expensive system to work" (Zero 3/15/2009 2:52:07 PM) |
| "Zero, I'm still not so sure. I used to work with the Ford engineers who designed suspensions and helped document their custom suspension design software, called DRIVE-COMPOSE. Remember that negative camber is controlled dynamically by the suspension geometry; its effect is to tilt the whole tire as the wheel is turned, thus keeping more of the tread on the road. Dynamic camber angle adjustment combined with racing tires and rims that have very short, rigid sidewalls do a pretty good job of keeping the tread on the road. However, I'm not an automotive engineer myself, so I can't settle it.
Just looking at the thing, you've got to wonder (as you do) how much it costs, how reliable it is and how quickly it can adjust to the road. Well, I guess someone will just have to build a full-sized model and try it out!" (Bill Christensen 3/15/2009 4:43:37 PM) |
