Vehicle disc brake device
View Patent ↗A vehicle disc brake device for preventing snow, ice, and mud from adhering to a caliper includes a body-anchoring part provided in a cylinder of a caliper, the body-anchoring part for securing a wire guide used to support a brake wire. The body-anchoring part has a first surface oriented along the longitudinal direction of the brake wire, and a second surface located on the side opposite the first surface. A wire-guide-anchoring part is secured to the second surface. The first surface is a flat, inclined surface.
1. A vehicle disc brake device comprising:
a pivoting lever secured to a rotary shaft for operating a mechanical brake mechanism to restrict rotation of a wheel of a vehicle, the rotary shaft being supported in a caliper having a cylinder;
a brake wire attached to the pivoting lever;
a body-anchoring part protruding, upon attachment of the disc brake device to the vehicle, from a side of a downwardly-directed bottom of the caliper cylinder outwardly in a radial direction of the cylinder; and
a wire guide secured to the body-anchoring part, for supporting the brake wire,
wherein the wire guide has a wire-guide-anchoring part secured to the body-anchoring part and a wire-supporting part connected to the wire-guide-anchoring part, for supporting the brake wire,
the body-anchoring part has a first surface positioned to face a length of the brake wire and a second surface positioned on a reverse side of the first surface,
at least the first surface comprises a flat surface and is inclined toward the second surface relative a line passing over a radial center of the cylinder and a center of a proximal end of the body-anchoring part, and
the wire-guide-anchoring part is secured to the second surface;
wherein a bolt threadingly extends through the wire-guide-anchoring part and the body-anchoring part and threadingly engages at least the body-anchoring part to secure the wire-guide-anchoring part to the body-anchoring part, and the bolt has a distal end issuing on the first surface and extending in a same direction as the first surface.
2. The disc brake device of claim 1 , wherein a length of the bolt is selected such that the distal end protrudes from the flat surface of the first surface of the body-anchoring part.
3. The disc brake device of claim 2 , wherein a length of protrusion of the distal end of the bolt is set to be smaller than a length of protrusion of a head part of the bolt.
4. The disc brake device of claim 1 , wherein a wide angle is formed by the first surface of the body-anchoring part and a substantially horizontal outer peripheral surface of the cylinder bottom.
