Abstract

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 respec…
