Abstract
A disc brake includes a pair of end-side connector parts that connect a pair of cylinder parts across over a disc rotor, and an intermediate connector part that is installed between the end-side connector parts and that connects the pair of cylinder parts across over the disc rotor and brake pads. The brake pads are provided with protrusion segments that are formed at positions that are outer end sides in a rotor radial direction and that protrude in directions separated from middle portions of the brake pads in a rotor rotational direction, and the end-side connector parts are provided with pad engaging faces on which inner regions in the rotor radial direction of the protrusion segments are oppositely disposed and which are formed of the same member as a caliper main body.
Claims13
A disc brake comprising:
- at least one pair of brake pads disposed to be opposite to a disc rotor;
- and
- a caliper main body configured to support the brake pads so as to be capable of being pressed to the disc rotor,
- wherein the caliper main body includes:
- a pair of cylinder parts in which pistons adapted to press the brake pads are housed;
- a pair of end-side connector parts configured to extend over the disc rotor at ends in a rotor rotational direction of the pair of cylinder parts and to connect the pair of cylinder parts;
- and
- an intermediate connector part installed between the pair of end-side connector parts and to connect the pair of cylinder parts across over the disc rotor and the pair of brake pads, wherein
- a pad spring is installed between the intermediate connector part and the pair of brake pads so as to bias the pair of brake pads;
- at least one of the pair of brake pads includes a pair of protrusion segments formed at positions that are outer end sides in a rotor radial direction and to protrude in directions separated from middle portions of the brake pads in the rotor rotational direction, and
- the pair of end-side connector parts respectively includes:
- disc path parts which the disc rotor passes through, and pad guides which are formed at both sides in a rotor axial direction of the disc path part and which movably support the pair of brake pads in the rotor axial direction, and
- pad engaging faces on which inner regions in the rotor radial direction of the protrusion segments are oppositely disposed and which support the brake pads in the rotor radial direction are formed of the same member as the caliper main body,
- wherein the inner regions in the rotor radial direction of the protrusion segments and the pad engaging faces face each other and are parallel with each other,
- wherein the pad spring is arranged so that a biasing force of the pad spring is transferred to the pad engaging faces via the inner regions in the rotor radial direction of the protrusion segments, and
- wherein at least one of the pad engaging faces of the pair of end-side connector parts is located at an outer side in the rotor radial direction relative to the disc rotor, crosses the disc rotor to continue to both sides in the rotor axial direction and forms an end face of the pad guide located at the outer side in the rotor radial direction.
