Got a note from Dodgy pointing to this video of the Carver 3 wheeler. I keep writing about developments in the 3 wheel direction because some of them look interesting and some are far better engineered than others, the Carver being one of the good ones.
Whether you have the 2 wheels up front, the more usual arrangement, or in the back like the Carver, the tilting action is where a lot of work seems to be going now. If you don’t tilt, you’ll be spinning out a lot, even if the rear tire is wide since you have limited weight and only one tire out back (again, in the more common arrangement). Tilting gives you the shifting center of gravity and motorcycle like steering. The Carver, though, gives you the tilt up front to shift weight but the two wheels in the rear remains planted for traction and drive, which then brings in a somewhat sophisticated mechanism for joining the two sections and controlling tilt which is more steep as the speed increases, low speed sharp turns are relatively straight up.
The Carver looks like a fun drive, as he comments in the video, you get the feeling of a fighter plane tilting and carving into the turns. It’s not cheap but maybe if production increases, the price will come down a bit. How many people would buy one? With all of the alternative vehicles coming on to the market these days, maybe more than you think. One of the limitations of anything out of the mainstream is the concern by some that they will look foolish or weird if they buy one. Now you could park this in your driveway because it’s fun yet pass it off to the neighbors as fuel efficient and green. Actually, if you buy one your neighbors will probably turn green … with envy, because it’s so cool.
Thanks for the tip, Dodgy!
