Publication number: 20200149586Abstract: A bearingless hub assembly comprising a rim hollowed to receive a tube magnet, and magnets embedded around the circumference of the rim on both ends. The rim is capped by front and rear rim plates configured to hold the embedded magnets in place and fitted to receive respective circular magnets. Similar magnets in corresponding front or rear drive plate maintain space (i.e., levitation) vis-à-vis the front and rear rim caps by repelling each other, thus allowing the rim (and, as applied, a mechanically-attached tire assembly) to move freely with no friction. The front and rear drive plate carry forward and reverse electromagnetic actuators as well as forward and reverse levitation control units, power generators and speed sensors. These components mount 360 degrees around the circumference of the drive plates while the embedded magnets of the rim spin through when in motion.Type: ApplicationFiled: November 9, 2018Publication date: May 14, 2020Inventor: BERNABE SEGURA CANDELARIA

Publication number: 20200149594Abstract: A clutch mechanism is used in a rotary power tool having a motor. The clutch mechanism includes an input member to which torque from the motor is transferred and an output member co-rotatable with the input member. The output member defines a rotational axis. A cam surface is formed on one of the input member or the output member. First and second compression springs are carried by the other of the input member or the output member for co-rotation therewith. A follower has a circular cross-sectional shape and is biased against the cam surface by the first and second compression springs. In response to relative rotation between the input member and the output member, the cam surface displaces the follower along a line of action coaxial or parallel with each of the first and second compression springs. The line of action does not intersect the rotational axis.Type: ApplicationFiled: January 17, 2020Publication date: May 14, 2020Inventor: Mitchell Carlson
