    • An apparatus and method for removably holding an axle includes an axle attachment which is removably attachable to an end of the axle. A threaded shaft is coupled to the axle attachment, and a latch is selectively engageable with the threads of the shaft. A crank is coupled to the shaft, and rotation of the crank results in advancement of the axle attachment towed the end of the axle, to clamp the axle between the axle attachment and a centering apparatus engageable with the opposite end of the axle. The latch is movable to a release position in which the latch is disengaged from the threads of the shaft. A spring bears against the crank so as to bias the axle attachment away from the end of the axle, and the spring functions to disengage the axle attachment from the end of the axle when the latch is moved to its release position. The centering apparatus is movable to varying positions so as to accommodate varying axle lengths and to provide proper centering of the axle.
    • 用于可拆卸地保持轴的装置和方法包括可拆卸地附接到车轴端部的车轴附件。 螺纹轴联接到轴附件,并且闩锁可选择性地与轴的螺纹接合。 曲柄联接到轴上,并且曲柄的旋转导致牵引到轴的端部的轴附件的前进,以将轴夹在轴附件和可与轴的相对端接合的定心装置之间。 闩锁可移动到释放位置,在释放位置,闩锁与轴的螺纹脱离。 弹簧靠在曲柄上,以便将轴附件偏离轴的端部,并且当闩锁移动到其释放位置时,弹簧用于使轴附件与轴的端部脱离。 定心装置可移动到变化的位置,以适应不同的轴长度并提供适当的轴心定心。
