Disc brake caliper

The invention relates to a 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 () adapted 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 disc brake at such a central aperture (). The caliper body () houses brake pads () supported by suspension pins for pads () arranged in an axial direction (X-X) of the caliper body; said pads have 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 (). Such a caliper () further comprises a first () and a second () cross-shaped leaf springs to influence the pads () in the axial direction (X-X), wherein such a first ()/second () spring is adapted to act between the pads () and between the first/second connection bridge () and the first/second end bridge () of the half-bodies (). The first ()/second () leaf spring comprises a bow-shaped longitudinal beam () having a shaped first end () adapted to be removably constrained to the first/second connection bridge () and an opposite shaped second end () adapted to be removably constrained to the first/second end bridge (). Wherein each of such 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 (), such a cross beam () includes wings () projecting from the central base portion () of the spring in the axial direction (X-X); each of such wings () has a surface () facing the disc of the disc brake suitable for resting 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 () by keeping it away from an inner wall () of the half-bodies (); each of such wings () comprises second means for influencing the pads () to influence the first side () of the pad () away from the disc in said axial direction (X-X) and to influence such a pad in suspension on the pins () in a direction (R) orthogonal to said axial direction (X-X) away from said first () and second () connection bridges.

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

A disc brake caliper, has a caliper body having a pair of half-calipers which define a housing compartment for a portion of an associable brake disc. The half-calipers being placed on opposite sides to the housing compartment in an axial direction parallel to the rotation axis of the associable brake disc. At least one half-caliper is fitted with at least one housing seat for a piston suitable to press a pad against the associable brake disc, in the axial direction. The housing seat passes through the respective half-caliper so as to extend between an inner wall facing the housing compartment and an outer wall of the half-caliper, axially opposite the housing compartment. A cup-shaped hollow insert is housed inside the housing seat so as to present a closed end wall, placed on the side of the outer wall of the half-caliper, and a cavity having an aperture facing axially towards the housing compartment. At least one piston is housed inside the cavity of the insert and is guided axially by an inner side wall of the insert.
