  • Patent number: 6732840
    Abstract: A brake cable connecting apparatus of a brake-actuating mechanism for a drum brake is mainly composed of a brake lever (22) and a strut (21). A cable end (24a) of a brake cable (24) is snapped into a free end (22e) of the brake lever (22) when the brake cable (24) is pulled in the cable operating direction against a spring force of a return spring (15) and disassembled therefrom when the brake cable (24) is removed from the free end (22e) while the brake lever (22) is pressed by a tool (30). A guide section (22h), for supporting a top of the tool (30), is formed on the brake lever (22) at a side relative to the cable releasing direction.

  • Publication number: 20020185341
    Abstract: A brake cable connecting apparatus of a brake-actuating mechanism for a drum brake prevents inadvertent disconnection of the brake cable from a brake lever while transporting a vehicle and disconnection the brake cable independently from the brake lever without dismounting a brake drum and disassembling a brake device.

  • Patent number: 6435317
    Abstract: A brake-actuating mechanism comprises a strut; an operating lever relatively pivoted with respect to the strut about a pivot pin, a brake cable including a cable end engaging with the lever and a resilient member provided to obstruct a cable end engagement recess of the operating lever. A brake cable-connecting apparatus of the brake-actuating mechanism designed to avoid a disengagement of the cable end from the lever without damaging or deforming the cable end and/or the lever. The resilient member deforms thoroughly allowing the cable end to go toward the cable end engagement recess when the brake cable is installed in the operating lever and avoids the cable end disengaging from the engagement recess while transporting a drum brake device with the brake cable.

  • Publication number: 20020014377
    Abstract: A brake cable-connecting apparatus of a brake-actuating mechanism designed to avoid a disengagement of a cable end of a brake cable from an operating lever without damage to the cable end, operating lever and other components, even during transportation of a drum brake device. The brake-actuating mechanism comprises a strut (11); an operating lever (12) relatively pivoted with respect to the strut (11) about a pivot pin (15) and a brake cable (16) including a cable end (16a) engaging with the lever (12). note: abstract must be a single paragraph.

  • Patent number: 6325183
    Abstract: A brake cable mounting structure for a drum brake which, even if the distance from the brake mounting surface to the brake shoe center in the width direction is short, secures an effective stroke of the brake cable, facilitates the layout of the brake cable mounting section and the crank mechanism, and reducing the size of the anchor by only needing to support the brake force. To that end, a brake cable mounting structure for a drum brake is provided, wherein the pipe-like section, in which the outer casing of the brake cable is attached, is formed integrally with the spacer positioned between a part of the back plate around the anchor which supports one adjacent ends of the pair of brake shoes and the brake mounting member.
