Disc brake and method of producing the disc brake
View Patent ↗Provided is a disc brake which solves, with a simple structure, the issue of interference between a carrier and an electric motor. A carder 3 applied to the disc brake includes a recess 28 in one arm 18 of the pair of arms 18 and 19 which recess is casted so as to be recessed in a direction toward a line, which is parallel to a tangent line L 3 tangent to an the pin hole boss 16 on one side and perpendicular to a line segment L 1 connecting centers of the pair of pin holes (pin hole bosses 16, 16 ) and extends through the center of the pin hole on the one side, with respect to the tangent line L 3 . This makes it possible to prevent or reduce the interference between the carrier 3 and the electric motor, with a simple structure.
1. A method of producing a disc brake including:
a pair of pads disposed, across a rotor, respectively on both sides of the rotor in an axial direction of the rotor; and
a carrier configured to support the pair of pads,
the carrier including:
an inner beam attached to a non-rotating portion of a vehicle;
a pair of inner arms extending from respective ends of the inner beam in a radial direction of the rotor;
pin inserting portions extending from the pair of inner arms across the rotor;
a pair of pin holes drilled in respective ends of the pin inserting portions along the rotor axial direction;
pin hole bosses formed around the pin holes; and
a recess formed on the one inner arm so as to be dented in a direction toward a line L 2 , which is parallel to a tangent line L 3 ,
the tangent line L 3 being perpendicular to a line segment L 1 connecting centers of the pair of pin holes and being tangent to an edge, on a side of the pin hole boss, of one of the pin holes at one side of the carrier,
the line L 2 extending through the center of the one side pin hole, with respect to the tangent line L 3 ,
wherein the method comprises forming the carrier by a pair of casting molds defining an interior product cavity corresponding to the carrier, the carrier being formed so that a line segment perpendicular to the line segment connecting the centers of the pair of pin holes is inclined relative to a mold opening/closing direction.
