Disc brake caliper body
Caliper bodies are provided which comprise two transversally spaced apart side formations and one or more transversally extending bridge portions, which connect the first and second side formations. Each bridge portion has a closed loop structure with an extrados, an intrados, two connecting portions transversally spaced apart connecting the extrados to the intrados and a through cavity, which extends in a tangential direction between the extrados and the intrados.
1. A disc brake caliper body having a U-shape, adapted to be arranged astride an outer peripheral edge of a brake disc, the caliper body comprising:
a first and a second side formation, transversely spaced from one another so as to face opposite braking surfaces of a brake disc;
two substantially parallel bridge portions extending transversely and connecting the first and the second side formations;
wherein at least one bridge portion of the two substantially parallel bridge portions has a closed loop structure with an extrados, an intrados, two connecting portions transversely spaced apart and connecting the extrados and the intrados, and a through cavity which extends in a tangential direction relative to an axis of rotation of the brake disc between the extrados and the intrados;
wherein the two substantially parallel bridge portions are spaced apart from one another in a tangential direction relative to an axis of rotation of the brake disc.
2. The caliper body of claim 1 , wherein each of the two substantially parallel bridge portions further comprises at least one radially extending pillar element which rigidly connects the extrados to the intrados.
3. The caliper body of claim 1 , wherein the extrados of the at least one bridge portion of the two substantially parallel bridge portions provides at least two parallel ribs tangentially spaced from one another relative to the axis of rotation of the brake disc.
4. The caliper body of claim 3 , wherein said pillar element is substantially equally spaced between the two connecting portions which connect the extrados to the intrados.
5. The caliper body of claim 1 , wherein the caliper body is a floating caliper body.
6. The caliper body of claim 5 , further comprising:
at least two parallel ribs tangentially relative to the axis of rotation of the brake disc spaced from one another on the extrados of the at least one bridge portion of the two substantially parallel bridge portions, and
wherein an opening elongated in a transversal direction is provided between the two parallel ribs.
7. The caliper of claim 1 , wherein the caliper body is a fixed caliper body.
8. The caliper of claim 1 , wherein the body is obtained by casting.
9. A brake caliper comprising the caliper body of claim 1 .
10. The caliper of claim 1 , wherein the caliper body is made in a single piece.
11. The caliper of claim 7 , wherein the fixed caliper body comprises two mutually facing and releasably connected caliper halves.
