Disc brake caliper employing a spring to influence pads acting on the disc of the disc brake
First Claim
1. Disc brake caliper comprising:
- a caliper body placed astride the disc of a disc brake, fitted with a pair of half-bodies connected to each other by means of a first and a second end bridge suitable to delimit a central aperture of the caliper body, and by means of a first and a second connection bridge placed astride the disc of the brake disc at said central aperture,said caliper body housing brake pads supported by suspension pins for pads positioned in an axial direction of the caliper body, said pads having a first side facing the disc of the disc brake, connected to an opposite second side by means of a corner facing said central aperture,said caliper further comprising a first and a second cross-shaped leaf spring to influence the pads in said axial direction,wherein said first/second spring is suitable to act between the pads and between the first/second connection bridge and the first/second end bridge of the half-bodies, said first/second leaf spring comprising a bow-shaped longitudinal beam having a shaped first end suitable to be removably constrained to the first/second connection bridge and an opposite second shaped end suitable to be removably constrained to the first/second end bridge,wherein each of said first and second leaf springs comprises;
a cross beam connected to the longitudinal beam at a central base portion of the spring, to influence the pads at suspension portions of the pads towards the pins,said cross beam including wings which project from the central base portion of the spring in said axial direction,each of said wings having a surface facing the disc of the disc brake suitable to rest on the corner of the respective pad,each of said wings comprising first means for influencing the pads to influence the second side of the pad keeping it away from an inner wall of the half-bodies, each of said wings comprising second means for influencing the pads to influence the first side of the pad away from the disc in said axial direction and to influence said pad in suspension on the pins in a direction orthogonal to said axial direction away from said first and second connection bridge.

Abstract
The invention relates to a disc brake caliper (100) comprising: a caliper body (10) placed astride the disc of a disc brake, fitted with a pair of half-bodies (11, 12) connected to each other by means of a first and a second end bridge (20, 21) adapted to delimit a central aperture (22) of the caliper body (10), and by means of a first (13) and a second (14) connection bridge placed astride the disc of the disc brake at such a central aperture (22). The caliper body (10) houses brake pads (2, 3) supported by suspension pins for pads (4, 4′, 5, 5′) arranged in an axial direction (X-X) of the caliper body; said pads have a first side (42) facing the disc of the disc brake connected to an opposite second side (44) by means of a corner (43) facing said central aperture (22). Such a caliper (100) further comprises a first (50) and a second (51) cross-shaped leaf springs to influence the pads (2, 3) in the axial direction (X-X), wherein such a first (50)/second (51) spring is adapted to act between the pads (2, 3) and between the first/second connection bridge (13, 14) and the first/second end bridge (20, 21) of the half-bodies (11, 12). The first (50)/second (51) leaf spring comprises a bow-shaped longitudinal beam (61) having a shaped first end (73) adapted to be removably constrained to the first/second connection bridge (13, 14) and an opposite shaped second end (74) adapted to be removably constrained to the first/second end bridge (20, 21). Wherein each of such first (50) and second (51) leaf springs comprises: a cross beam (62) connected to the longitudinal beam (61) at a central base portion (64) of the spring, to influence the pads (2, 3) at suspension portions of the pads (2, 3) towards the pins (4, 4′, 5, 5′), such a cross beam (62) includes wings (81, 82) projecting from the central base portion (64) of the spring in the axial direction (X-X); each of such wings (81, 82) has a surface (7) facing the disc of the disc brake suitable for resting on the corner (43) of the respective pad (2, 3); each of said wings (81, 82) comprising first means for influencing the pads (8, 83, 84) to influence the second side (44) of the pad (2, 3) by keeping it away from an inner wall (90) of the half-bodies (11, 12); each of such wings (81, 82) comprises second means for influencing the pads (85, 86, 55, 56) to influence the first side (42) of the pad (2, 3) away from the disc in said axial direction (X-X) and to influence such a pad in suspension on the pins (4, 4′, 5, 5′) in a direction (R) orthogonal to said axial direction (X-X) away from said first (13) and second (14) connection bridges.
