  • Patent number: 9567032
    Abstract: A brake caliper arrangement structure for a saddled vehicle, wherein a brake caliper for braking and a brake caliper for parking are provided on a swing arm. At least one or other of the brake caliper for braking and the brake caliper for parking is arranged in front of a rear axle being the axle of the rear wheel, when viewed from a side, at a position on a vehicle widthwise inside of the swing arm and overlapping the swing arm.
    Type: Grant

  • Patent number: 9440705
    Abstract: A brake caliper includes: a caliper body which slidably houses a mechanically operated piston which presses a brake disc; a rotation cylinder member which is arranged alongside the mechanically operated piston, coaxially with the mechanically operated piston, and which is rotatably supported on the caliper body; a rotation arm which is fixed to the rotation cylinder member, and which rotates the rotation cylinder member by means of an operation of an operating element; a conversion mechanism which is provided between the rotation cylinder member and the mechanically operated piston, and which converts rotary motion of the rotation cylinder member into axial linear motion of the mechanically operated piston to thereby press and move the mechanically operated piston toward the brake disc side; and a return spring which biases the mechanically operated piston in a direction of moving away from the brake disc.

  • Patent number: 7334666
    Abstract: A disk brake including friction pads disposed opposite to a brake disk, a bracket provided with support portions for movably supporting the friction pads so as to permit sliding along the axial direction of the brake disk, and retainers each interposed between the friction pad and the support portions, to restrain at least movements of the retainers relative to the support portions of the bracket. Of a pad holding force with which the retainer holds the friction pad, and a retainer supporting force for supporting the retainer on the support portion, at least the retainer supporting force is set to be not less than a received force exerted on the friction pad due to vibration. The resulting configuration prevents generation of rattling sounds due to the vibration.

  • Patent number: 7267204
    Abstract: In a disk brake of a vehicle, a caliper device which supports pads that can be pressed against a brake disk rotating with a wheel and which exerts a force to press the pads against the brake disk, is supported on a support member that supports an axle of the wheel. A recess that allows an entire thickness of the pad to be always visually identified from outside, is provided in a portion of a member that constitutes the caliper device, the portion covering the pad from outside. Thus, a degree of freedom in positioning of the caliper device is increased in checking a remaining amount of a pad.

  • Patent number: 7232014
    Abstract: In a motorcycle with a swing arm disposed on one side of a rear wheel for supporting the rear wheel. The swing arm is formed in a roughly triangular shape in a side view and a brake caliper of a rear brake is supported by the swing arm. The brake caliper is disposed relative to the rear brake so as to contrive a lowering of the center of gravity of the motorcycle and to enhance the rigidity of the swing arm. An opening portion is provided in a roughly central portion of a swing arm and a brake caliper is disposed in the opening portion.
