  • Patent number: 9341220
    Abstract: A brake pad retaining device is provided for holding a brake pad within a brake caliper of an air disc brake system. The device may be formed as a spring which provides at least four retention forces at longitudinal ends of the brake pad in order to suppress brake pad kick motion and vibration, while applying a biasing force that pre-loads a caliper to its mounting pins. The device may include a mounting section that is coupled to a brake carrier, a first projection and a second projection. The first projection extends from one region of the mounting section to a region near a longitudinal end of the brake pad to thereby exert a radially inward force against the brake pad. The second projection extends from another region of the mounting section to an inner surface of the brake caliper to thereby exert a biasing force against the brake caliper.

  • Publication number: 20150014103
    Abstract: A brake pad retaining device is provided for holding a brake pad within a brake caliper of an air disc brake system. The device may be formed as a spring which provides at least four retention forces at longitudinal ends of the brake pad in order to suppress brake pad kick motion and vibration, while applying a biasing force that pre-loads a caliper to its mounting pins. The device may include a mounting section that is coupled to a brake carrier, a first projection and a second projection. The first projection extends from one region of the mounting section to a region near a longitudinal end of the brake pad to thereby exert a radially inward force against the brake pad. The second projection extends from another region of the mounting section to an inner surface of the brake caliper to thereby exert a biasing force against the brake caliper.

  • Publication number: 20140345984
    Abstract: A pad pressing spring which is mounted on a pad of a disc brake by causing a pinching portion to pinch a pad back plate is configured as follows. An elastic arm which presses the pad in a disc rotor normal-rotating direction continuously extends from a base end side of the pinching portion, and the elastic arm has a configuration in which, when a load exceeding a predetermined value is applied in a direction opposite to a direction in which a pad is pressed, a tip end side of the elastic arm comes into contact with a lateral surface of the pad back plate or the pinching portion, and thus a spring constant of the pad pressing spring increases compared to a spring constant in a state where a load exceeding the predetermined value is not applied.

    Abstract: A system and method are provided for retaining brake pads in disc brakes, such as air-operated disc brakes utilized on commercial vehicles, and for installing and removing brake pads, without the need to employ brake pad retaining devices which radially over-top the brake pads. A preferred embodiment includes a retaining element, preferably a spring steel clip, having protrusions which face in opposite directions to engage corresponding slots in a brake pad lateral edge and in a brake pad carrier brake pad-facing surface. When installed in a radially-inward direction, the brake pad carrier side protrusion engages the brake pad carrier slot, and cooperates with the brake pad lateral side protrusion to resist brake pad movement in the radially-outward direction. The brake pad carrier side protrusion may be manually pressed toward the brake pad to disengage the protrusion from the carrier slot to permit withdrawal of the brake paid from the carrier.
