Mechanical disk brake caliper assembly

摘要

A mechanical disk brake caliper assembly includes a caliper body, a crank arm, a push member defines a push portion biasable by the crank arm, a first brake pad and a second brake pads disposed at two sides relative to a disk brake rotor, a lever arm pivoted to the caliper body and defining a driven arm portion and a bearing arm portion, and a horizontal displacement means for causing the push member to move during rotation of the push member. During movement of the push member, the push portion of the push member pushes the first brake pad and the driven arm portion, causing the bearing arm portion to move the second brake pad toward the first brake pad, and therefore the first and second brake pads are synchronously moved into operative engagement with the disk brake rotor.

主权项

1. A mechanical disk brake caliper assembly for operative engagement with a disk brake rotor, the mechanical disk brake caliper assembly comprising:
a caliper body defining a disk brake rotor slot for receiving a part of said disk brake rotor; a push member mounted in said caliper body and rotatable about an axis, said push member comprising a push portion and a mating connection portion; a crank arm comprising a connection portion connected to said mating connection portion of said push member and a driven portion connected to a brake cable; a first brake pad movably mounted in said disk brake rotor slot of said caliper body at one side relative to said disk brake rotor; a second brake pad movably mounted in said disk brake rotor slot of said caliper body at an opposite side relative to said disk brake rotor; a lever arm pivotally mounted in said caliper body, said lever arm comprising a driven arm portion abutted against said push portion of said push member and a bearing arm portion abutted against said second brake pad; and a horizontal displacement means for moving at least a part of said push member horizontally along said axis between a first position and a second position when said push member is rotated by an external force; wherein when said push member is moved horizontally from said first position toward said second position, the push portion of said push member pushes said first brake pad and said driven arm portion of said lever arm, causing said bearing arm portion of said lever arm to push said second brake pad in direction toward said first brake pad so that said first brake pad and said second brake pad are synchronously forced into operative engagement with said disk brake rotor.
