Abstract

A method for producing a hydraulic block of a slip-controlled hydraulic non-muscular-energy vehicle brake system. For the milling operation, the hydraulic block is clamped in two setups and a pump bore, into which the hydraulic block is clamped in the second setup, is produced in the hydraulic block in the first setup, thereby making it possible to machine five sides of the hydraulic block in the second setup free of clamping arrangement. Also described is a related hydraulic block.

First claim

What is claimed is:

1. A hydraulic block for a slip-controlled hydraulic vehicle brake system, comprising:
a cuboidal metal block;
a pump bore situated in the cuboidal metal block, the pump bore configured to accommodate a cylinder of a piston pump;
wherein the pump bore has at least one sealing groove, each of the at least one sealing groove being configured to receive a sealing ring which hydraulically seals the cylinder of the piston pump when the cylinder of the piston pump is installed in the pump bore;
wherein the pump bore has at least one circumferential groove, each of the at least one circumferential groove extending across an entire circumference of the pump bore, each of the at least one circumferential groove being separated from the at least one sealing groove and being configured to carry brake fluid around an outer circumference of the cylinder of the piston pump when the cylinder of the piston pump is installed in the pump bore;
wherein each of the at least one circumferential groove of the pump bore is further configured to receive a clamping jaw which extends from a clamping cylinder, the clamping jaw engaging with the at least one circumferential groove when the clamping cylinder is inserted in the pump bore during machining of the cuboidal metal block;
wherein the at least one circumferential groove includes at least two circumferential grooves separated from each other; and
wherein the hydraulic block further comprises:
the clamping cylinder situated in the pump bore; and
the clamping jaw engaged in the at least one circumferential groove.

2. The hydraulic block as recited in claim 1 , further comprising:
the sealing ring situated in each of the at least one sealing groove.

3. The hydraulic block as recited in claim 1 , wherein the at least one sealing groove includes at least two sealing grooves separated from each other.

4. The hydraulic block of claim 3 , wherein the cuboidal metal block has at least one oblique bore that does not extend parallel to at least one side of the cuboidal metal block and does not extend at a right angle with respect to the at least one side of the cuboidal metal block.

5. The hydraulic block of claim 3 , further comprising:
a master-brake cylinder bore situated in the cuboidal metal block.

6. The hydraulic block as recited in claim 3 ,
wherein a respective sealing ring is situated in each of the at least two sealing grooves.

7. The hydraulic block of claim 3 , wherein the pump bore terminates on an engine side of the cuboidal metal block provided for mounting an electric motor for driving a piston of the piston pump whose piston is accommodated in the cylinder of the piston pump.

8. The hydraulic block of claim 7 , wherein the pump bore extends to a control-unit side of the cuboidal metal block lying opposite from the engine side, which is provided for the mounting of solenoid valves and/or an electronic control unit of a slip control of a hydraulic vehicle brake system.

9. A hydraulic block for a slip-controlled hydraulic vehicle brake system, comprising:
a cuboidal metal block;
a pump bore situated in the cuboidal metal block, the pump bore configured to accommodate a cylinder of a piston pump;

wherein the pump bore has at least one sealing groove, each of the at least one sealing groove being configured to receive a sealing ring which hydraulically seals the cylinder of the piston pump when the cylinder of the piston pump is installed in the pump bore;
wherein the pump bore has at least one circumferential groove, each of the at least one circumferential groove extending across an entire circumference of the pump bore, each of the at least one circumferential groove being separated from the at least one sealing groove and being configured to carry brake fluid around an outer circumference of the cylinder of the piston pump when the cylinder of the piston pump is installed in the pump bore;
wherein each of the at least one circumferential groove of the pump bore is further configured to receive a clamping jaw which extends from a clamping cylinder, the clamping jaw engaging with the at least one circumferential groove when the clamping cylinder is inserted in the pump bore during machining of the cuboidal metal block;
wherein the at least one circumferential groove includes at least two circumferential grooves separated from each other;
wherein the at least one sealing groove includes at least two sealing grooves separated from each other; and
wherein the hydraulic block further comprises:
the clamping cylinder situated in the pump bore;
a respective clamping jaw of the clamping cylinder engaged in each of the at least two circumferential grooves, each of the respective clamping jaws extending from the clamping cylinder.
