Wheel wrench equipped with transmission system based on the ferguson paradox

摘要

Wheel wrench equipped with a transmission system based on the ferguson paradox, which is indicated by the numerical reference (100) and which serves to loosen or tighten screws or nuts for wheel maintenance or tire change which innovates by having a driving unit whose internal mechanism of rotation and torque transmission is based on the mechanism of the ferguson paradox. this mechanism, referred to as the driving unit, is mounted inside an external cover tube (1) and is basically composed by the eccentric input shaft (3) and through the external gears (17), fixed gear (18) and movable internal gear (19) having the turning crank and torque input as the drive crank (7) and the torque increased by the effect of the transmission ratio coming out through the rotating cover coupling (4) that attaches to sockets (14) to fit nuts or screws to tighten and loosen. It also innovates the present project by having a closing cover with coupling flange (5) that can be adapted in other vehicle maintenance equipment prepared for this coupling such as winches, windlass, jacks and vehicle lifters.
