Disc brake caliper employing a spring to influence pads acting on the disc of the disc brake

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.
