Device for restoring brake pads, and disc brake

A device for arranging and guiding a brake pad backplate and a brake pad in a brake slot of a disc brake, comprising a first restoring element which is arranged on the brake pad backplate such that a lower region of the brake pad backplate can be restored and a second restoring element which is arranged on the brake pad backplate such that an upper region of the back pad backplate can be restored;

• wherein the first restoring element comprises a wire spring which is arranged on a rear side of the brake pad backplate between both sides of the brake pad backplate via at least one fastening element to prevent loss such that free ends of the wire spring which abut against the two sides of the brake pad backplate extend in an axial direction and act between lateral guide surfaces of the pad slot and the brake pad backplate such that the brake pad backplate is slidingly supported on the lateral guide surfaces of the pad slot, and such that the wire spring is only able to absorb axial forces;
• wherein a second restoring element comprises a pad hold-down spring which comprises two openings into which lugs of the brake pad backplate are configured to engage in order to secure the pad hold-down spring on the brake pad backplate such that the pad hold-down spring cannot loosen, a sequence of differently inclined contact surfaces extends between the two openings via which the pad hold-down spring can be supported on a stationary abutment of the disc brake, and curvatures of the contact surfaces being selected transversely with respect to a longitudinal extent of the pad hold-down spring such that the pad hold-down spring is tilted between the abutment and the brake pad backplate during a braking stroke;
• wherein a curved portion of the pad hold-down spring rests on the brake pad backplate thereby supporting the tilting movement of the pad hold-down spring;
• and
• wherein the curved portion of the pad hold-down spring that rests on the brake pad backplate is curved transversely with respect to the longitudinal extent of the pad hold-down spring.

A disc brake, comprising:

• a device for arranging and guiding a brake pad backplate with a brake pad in a brake slot of a disc brake, comprising a restoring element which is arranged on the brake pad backplate such that an upper region of the brake pad backplate can be restored;
• wherein the restoring element comprises a pad hold-down spring which comprises two openings into which lugs of the brake pad backplate are configured to engage in order to secure the pad hold-down spring on the brake pad backplate such that the pad hold-down spring cannot loosen, a sequence of differently inclined contact surfaces extends between the two openings via which the pad hold-down spring can be supported on a stationary abutment of the disc brake, and curvatures of the contact surfaces being selected transversely with respect to a longitudinal extent of the pad hold-down spring such that the pad hold-down spring is tilted between the abutment and the brake pad backplate during a braking stroke;
• wherein a curved portion of the pad hold-down spring rests on the brake pad backplate thereby supporting the tilting movement of the pad hold-down spring;
• and
• wherein the curved portion of the pad hold-down spring that rests on the brake pad backplate is curved transversely with respect to the longitudinal extent of the pad hold-down spring.

A disc brake, comprising:

• a pad hold-down spring for a brake pad backplate for a disc brake, which comprises two openings into which lugs of the brake pad backplate are configured to engage in order to secure the pad hold-down spring on the brake pad backplate such that the pad hold-down spring cannot loosen, a sequence of differently inclined contact surfaces extends between the two openings via which the pad hold-down spring can be supported on a stationary abutment of the disc brake, and curvatures of the contact surfaces being selected transversely with respect to a longitudinal extent of the pad hold-down spring such that the pad hold-down spring is tilted between the abutment and the brake pad backplate during a braking stroke;
• wherein a curved portion of the pad hold-down spring rests on the brake pad backplate thereby supporting the tilting movement of the pad hold-down spring;
• and
• wherein the curved portion of the pad hold-down spring that rests on the brake pad backplate is curved transversely with respect to the longitudinal extent of the pad hold-down spring.
