초록 ▼

A system and method are provided for mounting, removing and retaining brake pads in disc brakes, such as air-operated disc brakes utilized on commercial vehicles, in a manner which does not require the use of separate brake pad retaining devices while providing positive retention of the brake pad. A preferred embodiment includes a brake caliper mount having brake pad abutment surfaces having radially-oriented and lateral grooves which permit a brake pad with corresponding projections on is lateral sides to be inserted through an opening of the brake caliper into the radially-oriented grooves until the backing plate projections are aligned with the lateral groove, and advancing the brake actuator behind the brake pad to place the brake pad in an operating position in which the actuator prevents the brake pad from realigning with the radially-oriented grooves until the actuator is retracted to permit brake pad extraction.

1. A disc brake, comprising: a brake disk;a brake caliper arranged to straddle the brake disk;a brake caliper mount arranged to receive the brake caliper; anda brake pad,wherein the brake caliper mount includes brake pad abutment portions arranged to limit motion of the brake pad in a circumferential direction of the brake disk, the brake pad abutment portions include at least one radially-oriented brake pad insertion feature and at least one lateral brake pad receiving feature oriented parallel to a rotation axis of the brake disk,the brake caliper includes a brake pad opening sufficiently wide in the circumferential direction of the brake disk to permit the brake pad to pass through the caliper into the at least one radially-oriented brake pad insertion feature without removal of the caliper from the caliper mount,the brake pad includes at least one pad retention feature of the brake pad corresponding to a first one of the at least one lateral brake pad receiving features of the caliper mount on a first lateral side of the brake pad, and a curved brake pad retention feature of the brake pad on a second lateral side opposite the first lateral side of the brake pad corresponding to a curved second one of the at least one lateral brake pad receiving features, andthe at least one radially-oriented brake pad insertion features and the at least one lateral brake pad receiving features are arranged to permit the brake pad to move radially when the brake pad is aligned with the at least one radially-oriented brake pad insertion feature and to move axially toward or away from the brake disk while being retained within the disc brake when the brake pad is not aligned with the at least one radially-oriented brake pad insertion feature. 2. The disc brake of claim 1, wherein a brake application device of the brake caliper is configured to prevent the brake pad from being aligned with the at least one radially-oriented brake pad insertion feature when the brake application device is advanced toward the brake disk. 3. The disc brake of claim 2, wherein the brake application device is configured to permit the brake pad to move in a radially-inward or radially-outward direction via the at least one radially-oriented brake pad insertion feature when the brake application device is withdrawn a sufficient distance away from the brake disk. 4. The disc brake of claim 1, wherein the at least one pad retention feature of the brake pad has a radially outer upper surface arranged at a non-perpendicular angle to a side surface of the brake pad. 5. The disc brake of claim 4, wherein the non-perpendicular angle of the at least one pad retention feature of the brake pad is an obtuse angle. 6. The disc brake of claim 4, wherein the at least one pad retention feature on the first lateral side of the brake pad and the first one of the at least one lateral brake pad receiving feature of the caliper mount have complementary surfaces arranged at the non-perpendicular angle to provide non-point contact between the at least one pad retention feature on the first lateral side of the brake pad and the first one of the at least one lateral brake pad receiving feature of the caliper mount. 7. The disc brake of claim 6, wherein the non-point contact is one of linear or planar contact.
