Caliper body for brake caliper, brake caliper, and disc brake

A caliper body for a brake caliper, adapted to be arranged straddling a brake disc,

• said brake disc comprising a brake disc first braking surface and an opposite brake disc second braking surface,
• said brake disc having a defined rotation axis defining an axial direction parallel to said rotation axis, a radial direction orthogonal to said axial direction and a circumferential direction orthogonal to both the axial direction and the radial direction,
• said caliper body comprising:
• a wheel-side first portion, adapted to face, either directly or indirectly through a first pad, said brake disc first braking surface to apply a braking action on said brake disc first braking surface;
• a vehicle-side second portion, adapted to face, either directly or indirectly through a second pad, said brake disc second braking surface to apply a braking action on said brake disc second braking surface;
• at least either said wheel-side first portion or said vehicle-side second portion comprising at least one thrust device housing adapted to accommodate a thrust device, adapted to bias said first pad or second pad respectively against the brake disc first braking surface or the brake disc second braking surface;
• said caliper body further comprising
• at least one bridge connecting said wheel-side first portion to said vehicle-side second portion and arranged straddling the disc brake;
• said at least one bridge, said wheel-side first portion and said vehicle-side second portion defining an inside of the caliper body, facing said brake disc either directly or indirectly, and a an outside of the caliper body opposite to the inside of the caliper body facing opposite or far from said brake disc;
• wherein said at least one bridge, said wheel-side first portion and said vehicle-side second portion separate the inside of the caliper body, in which a portion of said brake disc and said first and second pads are accommodable, from the outside of the caliper body;
• said at least one bridge comprising at least one ventilation opening adapted to put into communication the inside of the caliper body with the outside of the caliper body;
• said at least one bridge further comprising at least one conveying channel fluidically connected to the outside of the caliper body through said at least one ventilation opening;
• said at least one conveying channel extending longitudinally along the axial direction;
• wherein
• said at least one ventilation opening directly faces the inside of the caliper body in the axial direction to direct heat generated inside the caliper body in an outer axial direction towards the outside of the caliper body and conveyed outside by said at least one conveying channel through said at least one ventilation opening,
• said at least one conveying channel is delimited by a channel bottom surface, a disc inlet channel flank, and a disc outlet channel flank;
• said channel bottom surface is adapted to face towards the inside of the caliper body to delimit an extension of said at least one conveying channel in an outer radial direction;
• said disc inlet channel flank faces said disc outlet channel flank to delimit the extension of said at least one conveying channel in the circumferential direction;
• and
• said channel bottom surface, said disc inlet channel flank and disc outlet channel flank are adapted to define a cross-section shaped like a letter “U” and open towards the inside of the caliper body of the at least one conveying channel.
