Abstract

A brake carrier is provided for a disc brake having at least one brake pad, wherein the brake carrier includes: a wrap-around disc holder that wraps around a section of a brake disc of the disc brake in a frame-like manner; at least one brake pad slot in which the brake carrier guides the at least one brake pad, wherein the at least one pad slot is formed by carrier lugs, support surfaces and bridge struts on the wrap-around disc holder. The brake carrier is produced as a single piece using a shaping method and has a mold partition burr. The mold partition burr is arranged outside of the wrap-around disc holder.

First claim

What is claimed is:

1. A brake carrier for a disc brake having at least one brake pad, comprising:
a) a wrap-around disc holder which encompasses a portion of a brake disc of the disc brake to be assigned;
b) at least one brake pad slot in which the brake carrier guides the at least one brake pad;
c) wherein the at least one brake pad slot is formed by carrier lugs, support faces, and bridge struts on the wrap-around disc holder; and
d) the brake carrier is integrally produced by a primary forming method and has a mold partition burr,
wherein
e) the mold partition burr is disposed outside the wrap-around disc holder, and
f) the mold partition burr is in each case disposed on a free end of the carrier lugs.

2. The brake carrier as claimed in claim 1 , wherein
the brake carrier has a fastening flange.

3. The brake carrier as claimed in claim 2 , wherein
the brake carrier has a reinforcement rib which is disposed on an external side of the brake carrier that faces away from the fastening flange.

4. The brake carrier as claimed in claim 3 , wherein
the reinforcement rib has a continuous contour geometry.

5. The brake carrier as claimed in claim 3 , wherein
the wrap-around disc holder has frame portions.

6. The brake carrier as claimed in claim 5 , wherein
one or both of the frame portions, in each case proceeding from a respective end of the reinforcement rib, widens in each case up to an external periphery of the side of brake carrier that faces the fastening flange.

7. The brake carrier as claimed in claim 1 , wherein
one set of carrier lugs has a height that is dissimilar to that of another set of carrier lugs.

8. The brake carrier as claimed in claim 7 , wherein
the set of carrier lugs on the side of the brake carrier that faces the fastening flange have in each case a greater height than the set of carrier lugs on the side of the brake carrier that faces away from the fastening flange.

9. The brake carrier as claimed in claim 1 , wherein
the brake carrier is produced by a casting method.

10. The brake carrier as claimed in claim 9 , wherein
the brake carrier is produced in a casting method having a permanent casting pattern and a lost casting mold.

11. A disc brake comprising a brake carrier as claimed in claim 1 .

12. A casting mold, comprising:
two mold halves for producing a brake carrier as claimed in claim 1 , wherein
one mold half has an upstanding mold face,
the other mold half has a suspended mold face,
the two mold faces shape a brake disc slot of the brake carrier, and
the upstanding mold face and the suspended mold face abut at a mold partition face, wherein the mold partition face is in each case disposed above the carrier lugs of a casting pattern incorporated in the mold of the brake carrier.

13. A method for producing a brake carrier, the method comprising the steps of:
a) providing a casting pattern of the brake carrier;
b) molding an upper mold half in a mold material while using the casting pattern, wherein the upper mold half has a suspended mold face for molding a brake disc slot of the brake carrier;
c) removing the molded casting pattern from the upper mold half;
d) molding a lower mold half in a mold material while using the casting pattern, wherein the lower mold half has an upstanding face for molding the brake disc slot of the brake carrier;
e) removing the molded casting pattern from the lower mold half;
f) assembling the lower mold half and the upper mold half so as to form a casting mold, wherein the upstanding mold face and the suspended mold face mutually abut at a mold partition face which is disposed above carrier lugs of the casting model incorporated in the mold;
g) pouring a liquid material into the casting mold;
h) unpacking the brake carrier after cooling from the casting mold by destroying the casting mold;
j) cleaning the brake carrier; and
k) machining the brake carrier,
wherein after the pouring step, the brake carrier has a mold partition burr disposed on a free end of the carrier lugs.

14. The method as claimed in claim 13 , wherein method step j) includes removal of a mold partition burr.
