Parking brake manual release mechanism

摘要

A quick release mechanism (10) including a sleeve (16) having an external circumferential groove (14) and a locking ring (12) located on the sleeve and sized to seat in the groove. The locking ring is split at one location to provide split-end portions (20), and a rotatable clamping device (26) is provided with a recess (30) for receiving the split-end portions. The recess has narrow and wide dimensions that serve to engage and disengage the split-end portions of the locking ring to effect closing of the locking ring in the circumferential groove when the clamping device is rotated to present a narrow dimension to the split-end portions, and to open the locking ring when the wide dimension of the elongated slot is presented to the split-end portions.
