MAG-LEV Wheel-Tire Motor-Brake

A re-think of wheels and tires, suspension and bearings for cars.
(+2, -2)
  [vote for,

I propose an integration of MAG-LEV technology into regular tire's for cars, that would slip over a slim rim, born by a magnetic field, from a static (non-rotating) hub/'wheel', suspended to the car.

The tire would be fairly regular, even very low profile, since the magnetic field would be 'micro'-movement cushioning.

There would be an outer rim, rotating with the tire, and the inner rim, supported to the car's structure.

Between them, a magnetic field, holding the rims slightly apart, and introducing the drive and brake forces, to propel and arrest the vehicle/car.

Magnetic bearings http://en.wikipedia...ki/Magnetic_bearing
Big, heavy & expensive. [Twizz, Jun 01 2011]

MaglevLA_20Wheel Redundant. Even the first comment is nearly the same. [spidermother, Jun 01 2011]


       So the idea is to use a magnetic bearing (WKTE - see link) for automotive road wheels.   

       The friction from road wheel bearings is so small that a magnetic bearing is not justifiable in terms of energy consumption, weight, complexity or cost.   

Twizz, Jun 01 2011

       Yes, the function of the bearings would be included, but also the engine and the brakes - as the MAG-LEV trains, only in smaller rotation elements - both propulsion, AND braking comes through the magnetic field (segments around the circumference, switching opposing polarity, for attraction and distance.).   

       Interesting link.

       [spidermother] : Not the same construction. The link's center is a bearing, and something else is at the rim.
sirau, Jun 01 2011

       It's not that clearly worded, but the linked idea's author, in an annotation, mentions conventional bearings as an _alternative_ to magnetic levitation. The idea itself is the same as yours, except for the T-shaped construction to prevent sideways movement.

       You've partially described regenerative braking: an electric motor is a maglev... minus the 'lev' bit.   

       As far as the levitation bit is concerned, good luck finding a magnet that will do this: you've got (charitably) half a tonne on an area of a couple centimeters, which almost sounds doable until you hit a pothole.

       the support area is the entire circumferential area of the outer rim - inner rim interface, ie in vertical perspective : width x diameter of mag-lev 'shell', approximately the same as width x diameter of the wheel/tire.
