Contactless electronic control system for modular motorized wheel hub

A contactless electronic control system comprising

• a tubular bracket having two ends;
• a tubular grip member having two ends and encircling the bracket around a common axis therewith;
• a rotary connection between the grip member and the bracket so that the grip member can rotate relative to the bracket about said axis through a range of relative angular positions on either side of a home position;
• a ring magnet having diametrically opposite poles and being mounted inside the grip member for rotation therewith about said axis;
• an electrical device mounted in said bracket opposite the magnet, said device producing a continuously variable electrical signal whose value depends upon the relative angular position of said magnet and said device, said signal being positive when the grip member is rotated to one side of the home position and negative when the grip member is rotated to the other side of the home position, and
• means for establishing a home position of the grip member which locates the electrical device between the magnet poles.

• a rotary connection between the grip member and the bracket so that the grip member can rotate relative to the bracket about said axis through a range of relative angular positions, said rotary connection including a bearing between one end of the bracket and one end of the grip member;
• an end cap engaging the other end of the grip member and defining therewith and with the other end of the bracket a ball bearing track, and a circular array of ball bearings in said track;
• a ring magnet having diametrically opposite poles and being mounted inside the grip member for rotation therewith about said axis, and
• an electrical device mounted in said bracket opposite the magnet, said electrical device producing an electrical signal whose value depends upon the relative angular position of said magnet and said device.

• an annular inner pole piece concentrically positioned in the bracket;
• an annular outer pole piece concentrically positioned in the grip member, said magnet being located between said inner and outer pole pieces, and
• biasing means for biasing the grip member and the bracket relatively to a home position which locates at electrical device substantially midway between the magnet poles.
