The present invention concerns a disc brake locking assembly. Specifically, a lock is employed to control the up-down movement of a controlling cotter, and the disc brake locking assembly is placed in the locked position by causing the catch on the front of the controlling cotter to bind to the catch section of a locking rod. Said disc brake locking assembly possesses a moving piece. The top of said moving piece is equipped with a protruding pin, and the bottom of said moving piece is equipped with a slot A into which a spring is to be inserted. Said moving piece also possesses another slot B. A pin is installed into the main body in such a manner that allows one end of said pin to penetrate through said main body and join with the slot B in the moving piece. The restitution action of the spring allows said moving piece to move back and forth axially within a specified range. The left side of said moving piece is also equipped with a round slot into which a spring and locking rod are inserted in said order. The configuration allows the locking rod to move back and forth. Accordingly, said disc brake locking assembly equipped with said locking rod is capable of sensing the presence of a ventilation opening, when the opening slot is inserted into the braking disc and the locking rod comes into contact with said braking disc, thereby eliminating the need of finding a ventilation opening on the disc brake and aligning it manually and facilitating the locking operation.

A disc brake locking assembly comprising: a lock body, a moving piece, a locking rod having a locking rod slot and a catch section, a controlling cotter having a lock tongue receiving slot and a catch, and a lock cylinder having a tongue at its interior end; said lock body including a slot-like opening, said opening having side walls and including a rectangular slot in a lower end thereof; said slot and said side walls having cushioning means; said lock body further including a receiving aperture to receive said moving piece, a cotter hole having a longitudinal axis substantially parallel to the sidewalls of the slot-like opening to receive said controlling cotter and a first biasing spring, a lock hole perpendicular to and intersecting with the cotter pin hole to receive said lock cylinder, an interior lock hole having an axis perpendicular to and intersecting with the slot-like opening to receive a rounded end of said locking rod when the locking rod is in a locked position, and a first pin that limits movement of said moving piece in said lock body, said first pin engaging a slot in the moving piece; said moving piece being formed generally in the shape of a FIG. 8, an upper portion of said moving piece having a lateral hole to receive said locking rod and a second biasing spring, said upper portion of said moving piece further including a vertical hole to receive a second pin that limits movement of said locking rod in said moving piece, said second pin engaging said locking rod slot in the locking rod, a lower portion of said moving piece including a hole to receive a third biasing spring; said rounded end of said locking rod being biased by said second spring into said slot-like opening; wherein said locking assembly is adapted to receive a braking disc in said slot-like opening in said lock body; whereby the braking disc contacts said rounded end of said locking rod, overcoming the biasing force of said second biasing spring and forcing said locking rod out of said slot-like opening until a position of said locking rod corresponds to a position of a ventilation hole in said braking disc resulting in said second biasing spring urging said rounded end of said locking rod into said ventilation hole; said locking rod being movable to the locking position by the moving piece being moved into the lock body against the force of said third biasing spring whereby the locking rod and the moving piece are locked in the locking position by engagement of the catch of the cotter pin with the catch section of the locking pin; and wherein the lock assembly may be disengaged from the brake disk by turning said lock cylinder such that said tongue on the lock cylinder drives said controlling cotter against the force of the first biasing spring to disengage said controlling cotter from said locking rod, which in turn allows the force of said third biasing bring to push said moving piece outward from the lock body, thereby retracting said locking rod from said braking disc to a position where only said rounded end of said locking rod contacts said braking disc, whereby the locking assembly may be removed from the locking brake upon overcoming the force of said second biasing spring.
