Abstract
A brake assembly is suitable for use in conjunction with a wheel having a rim rotatably mounted to an axle. The brake assembly includes a rotor configured to rotate about the axis with the rim. The rotor has a first frustoconical rotor surface and either a conductive element or a magnet. The brake assembly further includes a stator fixed in rotation about the axis and configured for selective translation parallel to the axis. The stator has a first frustoconical stator surface proximate to the first frustoconical rotor surface and a conductive element, when the stator has a magnet, or a magnet, when the stator has a conductive element.
Claims9
A brake assembly for a vehicle having a wheel with a rim rotatably mounted to an axle about an axis, the brake assembly comprising:
- a first rotor configured to rotate about the axis with the rim, the first rotor comprising (i) a first frustoconical rotor surface and (ii) a first element comprising one of a conductive material and a magnetic material;
- a second rotor configured to rotate about the axis with the rim, the second rotor comprising (i) a second frustoconical rotor surface and (ii) a second element comprising the same one of the conductive material and the magnetic material as the first rotor;
- and
- a stator fixed in rotation about the axis and configured for selective translation parallel to the axis, the stator comprising (i) a first frustoconical stator surface proximate to the first frustoconical rotor surface (ii) a second frustoconical stator surface proximate to the second frustoconical rotor surface, the first and second frustoconical stator surfaces comprising the other of the conductive material and the magnetic material as the first and second rotors.
