Abstract
A disc brake includes: an inner pad and an outer pad; a pressing device configured to press the inner pad and the outer pad against a rotor, the pressing device including a first presser member and a second presser member that are movable parallel to a rotational axis of the rotor, and a frame that is a frame-shaped rigid body and is movable in the direction parallel to the rotational axis; and a housing mounted on a non-rotating body, the housing holding the pressing device, the housing including a pad pin that hold the inner pad and the outer pad so as to be movable in the direction parallel to the rotational axis, the pad pin being held by the housing at both ends of the pad pin in the direction parallel to the rotational axis.
Claims13
A disc brake comprising:
- an inner pad and an outer pad located so as to sandwich a rotor that rotates along with a wheel;
- a pressing device configured to press the inner pad and the outer pad against the rotor, the pressing device including
- a first presser member and a second presser member that are movable parallel to a rotational axis of the rotor, the first presser member being movable in a direction toward the rotor, the second presser member being movable in a direction away from the rotor and
- a frame that is a frame-shaped rigid body, the frame including a first edge facing the outer pad and a second edge separated from the first edge in a direction parallel to the rotational axis of the rotor and engaging with the second presser member, the frame being movable in the direction parallel to the rotational axis;
- and
- a housing mounted on a non-rotating body, the housing holding the pressing device and holding the inner pad and the outer pad, the housing including a pad pin that hold the inner pad and the outer pad so as to be movable in the direction parallel to the rotational axis, the pad pin being held by the housing at both ends of the pad pin in the direction parallel to the rotational axis.
A disc brake comprising:
- an inner pad and an outer pad located so as to sandwich a rotor that rotates along with a wheel;
- a pressing device configured to press the inner pad and the outer pad against the rotor;
- and
- a housing that is mounted on a non-rotating body and holds the pressing device and holds the inner pad and the outer pad, wherein:
- the pressing device includes
- a first presser member and a second presser member that are movable parallel to a rotational axis of the rotor, the first presser member being movable in a direction toward the rotor, the second presser member being movable in a direction away from the rotor and
- a frame that is a frame-shaped rigid body, the frame including a first edge facing the outer pad, a second edge separated from the first edge in a direction parallel to a rotational axis of the wheel and engaging with the second presser member, and a third edge and a fourth edge separated from each other in a direction orthogonal to the rotational axis and extending in a direction intersecting the first edge and the second edge, is the frame being movable in the direction parallel to the rotational axis;
- and
- when a straight line passing through a center of the first presser member and a center of the second presser member is defined as a center line, a straight line orthogonal to the center line and the rotational axis of the rotor is defined as a reference line, and a plane orthogonal to the reference line and including the center line is defined as a central reference plane, a centroid of each of a plurality of cross-sections of the third edge and the fourth edge extending in the direction orthogonal to the rotational axis is located in the central reference plane.
