Brake caliper and associated production method

1. A brake caliper for a disk brake system of a motor vehicle, the brake caliper comprising:

a caliper body cast from one of a light metal alloy or a light metal, said caliper body having two cheeks extending parallel to one another and over a length of the brake caliper, said caliper body further having a plurality of webs extending transversely with respect to said cheeks and connecting said cheeks to one another on an end side;

a skeleton structure cast into said caliper body and said caliper body encasing said skeleton structure, said skeletal structure being a cap shaped covering having two longitudinal members extending parallel to one another, and in each case said longitudinal members being embedded into one of said cheeks of said caliper body, said skeleton structure further having a plurality of cross-members extending transversely with respect to said longitudinal members and connecting said longitudinal members to one another, said cross-members in each case being embedded into one of said webs; and

a plurality of anchorings connecting said caliper body with said skeleton structure, said anchorings in each case positively connecting an anchoring point of said skeleton structure with an anchoring point of said caliper body, each of said anchorings having an anchor bolt, an anchor nut and an anchor sleeve, said anchor bolt penetrating through said anchor sleeve, inserted into said caliper body and supported on said skeleton structure;

said skeleton body having a through orifice formed therein into which said anchor nut engages, said anchor nut being at least one of capable of being supported on said skeleton structure or of passing through said caliper body.

2. The brake caliper according to claim 1 , wherein said skeleton structure is composed of a plurality of elements.

3. The brake caliper according to claim 1 ,

wherein said skeleton structure is formed from a material having a higher modulus of elasticity than a material of said caliper body.

4. The brake caliper according to claim 1 , wherein said skeleton structure is formed from one of an iron alloy and iron.

5. The brake caliper according to claim 1 , wherein said skeleton structure is formed from a matrix composite material.

6. The brake caliper according to claim 1 , wherein said caliper body is formed from one of an aluminum alloy and aluminum.

7. The brake caliper according to claim 1 , wherein a material forming said caliper body has a lower density than a material forming said skeleton structure.

8. The brake caliper according to claim 1 , wherein said caliper body has an inner structure for at least one of a reception of hydraulic fluids and a guidance of the hydraulic fluids.

9. The brake caliper according to claim 1 , wherein said skeleton structure is configured as a casting produced integrally in one piece.
