An improved quick disengagement apparatus is provided for selectively altering the positioning of an axially translatable member between an axially biased first position and a second position in opposition to said axial bias, and for releasably locking said translatable member in at least said second position. The mechanism is especially adapted for use with power wheel hub assemblies, such as may be commonly employed in vehicles and agricultural implements or the like, in which provisions are to be made for disengaging the hub from an associated power shaft. The apparatus in accordance with the present invention provides a housing, mountable to the hub assembly, which carries an axial plunger, engageable with a distal end of the axially translatable power shaft, and a transverse release plunger, acting under a yieldable bias to interlock with the axial plunger to retain the axial plunger in a position whereat the power shaft is disengaged from the hub assembly. Translation of the transverse release plunger in opposition to its yieldable bias releases the axial plunger so that the power shaft and the axial plunger may translate to the engaged position of the power shaft with respect to the hub.

A quick disengagement apparatus for selectively controlling a conventional disengageable power wheel assembly wherein an axially shiftable power shaft may be translated from a first position whereat said power shaft is operatively engaged with an associated hub assembly to enable mutual coaxial rotation, to, in opposition to a yieldable bias acting axially on said power shaft, maintain said engagement, a second position whereat said power shaft is disengaged from its associated hub assembly to enable independent coaxial rotations thereof, said quick disengagement apparatus comprising: a housing, disposed in a fixed location relative to said hub assembly; axial translatable means, carried by said housing, for communicating an axially directed external force applied thereto to said power shaft in opposition to said yieldable bias acting thereon so as to cause said power shaft to assume its disengaged position, said axially translatable means including a shoulder surface and a detent cavity formed therein at appropriate longitudinal positions respectively corresponding to said engaged and disengaged positions; transversely translatable means, carried by said housing, for releasably interlocking with said detent cavity and for retaining said axially translatable means in its axially translated position whereat said power shaft is disengaged from said hub assembly, release of said interlocking enabling said axially translatable means to translate to its axially translated position whereat said power shaft is engaged with said hub assembly; means for yieldably biasing said transversely translatable means into interlocking engagement with said detent cavity of said axially translatable means when said axially translatable means has attained said disengaged condition; and said axially translatable means further including a longitudinal slot formed diametrically therethrough at a laterally central region, the transversely translatable means extending through said slot and being supported in said housing on opposite sides of said axially translatable means, the slot enabling said axially translatable means to be shifted with respect to said transversely translatable means at least between its engaged position and its disengaged position, the assembly of the transversely translatable means through the slot of the axially translatable means allowing the transversely translatable means to serve as the sole means for retaining the axially translatable means in the housing.
