Mechanical type double-acting brake caliper assembly and caliper having the same

A mechanical double-acting brake caliper assembly, including:

• two caliper bodies, each having a recess, an axial hole communicated with the recess, the two caliper bodies fixedly connected to each other with the two recesses face-to-face, the two caliper bodies forming a receiving space between and communicating the two recesses;
• two axially-movable mechanisms, respectively disposed through the two axial holes and axially movably assembled to the two caliper bodies, each axially-movable mechanism including a driven end extending outside a respective one of the two caliper bodies and an actuating end arranged in the receiving space, the actuating end of the respective axially-movable mechanisms provided for driving a lining assembly to move toward an object;
• two arm members, extending in opposite directions with an included angle from the respective driven ends, each arm member having a first end and a second end corresponding to the first end, each of the first ends fixedly connected to a respective one of the driven ends in a co-rotatable relationship, each of the second ends having an installation portion, one of the installation portions of the second ends provided for a cable to dispose therethrough and the other provided for fixing a distal end of the cable;
• a first elastic member, having an abutting portion and two elastic arms extending away from each other from the abutting portion, the abutting portion engaged to one of the two caliper bodies, distal ends of the two elastic arms engaged with the respective installation portions;
• wherein when the cable is pulled, the installation portions approach to each other and the actuating ends of the respective axially-movable mechanisms are driven to move the lining assembly to come toward the object;
• wherein a bottom end of one of the two caliper bodies is formed with an engaging slot opening downward, the abutting portion is restrictedly engaged within the engaging slot, the two elastic arms are arranged by the same side of the caliper body and respectively extend toward upper-right and upper-left, and each elastic arm is at least partially abutted against a lateral face of the caliper body.

• a saddle elastic member, saddled on the two caliper bodies, having two installation ends disposed between corresponding arm member and caliper body and two lateral portions, the installation ends are respectively disposed at the two driven ends, the two lateral portions respectively extend upward from the installation ends;
• a return elastic member, disposed between the installation portions;
• wherein when the cable is pulled, the installation portions get closer to each other and drive the actuating ends of the respective axially-movable mechanisms to move the lining assembly to come toward the object and to compress the return elastic member at the same time.
