Caliper bodies for disc brakes

1. A caliper body for a disc brake comprising:

a mounting-side elongated portion equipped with at least one mounting portion configured for being connected to a support for the caliper,

said mounting-side elongated portion comprising a first end and a second end;

a non-mounting-side elongated portion comprising a first end and a second end,

each elongated portion housing or forming at least two cylinders each configured for receiving a piston to exert pressure on at least one pad,

said elongated portions being connected together by a first end bridge that connects the two first ends,

said elongated portions being connected by a second end bridge that connects the two second ends,

at least three central bridges connecting the two elongated portions between the two end bridges,

each of said at least three central bridges connecting to said elongated portions at the side of said at least two cylinders, so as to radially cover no more than half the cylinder, and forming at least four windows passing through said caliper body;

wherein at least two of said at least three central bridges are arranged lateral to the at least two cylinders such that there are no cylinders between these at least two central bridges.

2. The caliper body of claim 1 further comprising a further central bridge, so that at least said four central bridges are defined as two intermediate bridges and two middle bridges,

said at least four central bridges being arranged so as to connect the two elongated portions between said first and second end bridges,

wherein said caliper body also comprises a further cylinder, and wherein said two intermediate bridges and said two middle bridges form at least five windows passing through said caliper body.

3. The caliper body of claim 1 , wherein each bridge of said at least three central bridges and said first and second end bridges comprises:

a first joining portion joined to the mounting-side elongated portion arranged substantially in the radial direction (R-R),

a second joining portion joined to the non-mounting-side elongated portion arranged substantially in the radial direction (R-R),

a third bridge portion joined to the first joining portion and to the second joining portion and arranged substantially in the axial direction (A-A),

wherein said first and second joining portions and said third bridge portion form a “U” shape.

4. The caliper body of claim 2 , further comprising a plurality of tangential bridges, each tangential bridge connecting two adjacent central or end bridges so as to define between each tangential bridge and each of the two adjacent central or end bridges two through-windows through the caliper body.

5. The caliper body of claim 4 , wherein said plurality of tangential bridges comprises:

a first end tangential bridge, which is located between said first end bridge and an intermediate bridge

so as to form a mounting-side first window and a non-mounting-side first window,

a second end tangential bridge, which is located between said second end bridge and an intermediate bridge

so as to form a mounting-side second window and a non-mounting-side second window;

at least two intermediate tangential bridges, wherein each tangential bridge is located between each intermediate bridge and the adjacent middle bridge

so as to form at least two mounting-side third windows and at least two non-mounting-side third windows,

at least one central tangential bridge being located between said two middle bridges

so as to form at least one mounting-side fourth window and at least one non-mounting-side fourth window.

6. The caliper body of claim 1 , wherein two adjacent bridges provide a through-window that crosses the caliper body in the axial direction.

7. The caliper body of claim 1 , wherein the end bridges have a foil-shaped bridge body.

8. The caliper body of claim 1 , wherein the end bridges lie substantially in the same plane.

9. The caliper body of claim 1 , wherein said mounting-side elongated portion and said non-mounting-side elongated portion extend in the tangential direction substantially in an arc of a circle housing or forming the cylinders that project from said mounting-side elongated portion and said non-mounting-side elongated portion in a radial outward direction and in the opposite radial direction.

10. The caliper body of claim 2 , wherein said two middle bridges are connected together by a central tangential bridge directed tangentially and together with said middle bridges define two through-windows that in the radial direction have a bulb-shaped edge.

11. The caliper body of claim 2 , wherein said intermediate bridges house or form mounting portions of the caliper body to a stub axle.

12. The caliper body of claim 1 , wherein said at least three central bridges comprise a portion that projects to the non-mounting-side elongated portion with a radially outer surface in which a lightening groove is formed.

13. The caliper body of claim 2 , wherein said mounting-side and non-mounting-side elongated portions each house or form three cylinders and are connected together by said two middle bridges, said two intermediate bridges and by said first and second end bridges and by tangential bridges defining ten through-windows in the radial direction to the caliper body and in the axial direction to the caliper body, wherein the caliper body consists of three cylinders including said at least two cylinders and wherein the caliper body consists of a total of six bridges including said first and second end bridges, said two middle bridges, and said two intermediate bridges.

14. The caliper body of claim 1 , wherein said caliper body is a monoblock or a body in a single piece and/or a caliper body formed from at least two half-bodies.

15. The caliper body of claim 1 , wherein there are two adjacent bridges without the interposition of cylinders between them.

16. The caliper body of claim 2 , wherein between said at least two middle bridges there is at least one further bridge extending tangentially.

17. The caliper body of claim 2 , wherein between the first end bridge and the adjacent intermediate bridge there is a tangential bridge that in the radial direction is substantially V-shaped or substantially V-shaped with rounded edges.

18. A caliper for a disc brake comprising the caliper body of claim 1 .
