Abstract

A method for manufacturing a hydraulic device is described, in which at least one hydraulic channel and at least one connection are manufactured and/or hydraulically connected to one another, the hydraulic device being manufactured from at least two plates, and the plates being formed and connected to one another with the aid of the processes of cold forming, deep drawing, punching, punch riveting, and/or clinching.

First claim

What is claimed is:

1. A method for manufacturing a hydraulic device, in which at least one hydraulic channel and at least one connection are at least one of manufactured and hydraulically connected to one another, the hydraulic device including at least one of: a hydraulic module of a transmission, or a valve module for filling and emptying a hydraulic accumulator; the method comprising:
forming at least two plates with the aid of a process including at least one of: cold forming, deep drawing, or punching;
situating at least one intermediate plate between the at least two plates, wherein the at least one hydraulic channel is formed in the at least one intermediate plate to allow an exchange of fluid between cavities provided in the hydraulic device; and
forming a plurality of deformations in the at least one intermediate plate and the at least two plates along edge sections, to permanently connect and hydraulically seal the at least two plates and the at least one intermediate plate to one another at the edge sections, using at least one of: punch riveting, or clinching;
wherein at least punching and punch riveting processes are carried out in the same work step.

2. The method as recited in claim 1 , wherein at least one of: a component and at least one hydraulic assembly, is integrated into the hydraulic device before shaping.

3. The method as recited in claim 1 , wherein the at least two plates are semifinished products implemented as a coil.

4. The method as recited in claim 1 , wherein the plurality of deformations are formed by passing a ram into the at least two plates.

5. The method as recited in claim 1 , wherein the plurality of deformations are arranged in at least one line along at least one of the edge sections.

6. The method as recited in claim 1 , wherein the plurality of deformations are arranged in a plurality of lines along a plurality of the edge sections.

7. The method as recited in claim 1 , wherein the deformations are used to fasten supports on the at least one intermediate plate.

8. The method as recited in claim 1 , wherein the at least two plates are connected to one another by employing the at least one intermediate plate.

9. The method as recited in claim 8 , wherein the at least one intermediate plate is formed by at least one of cold forming, deep drawing, punching, punch riveting, and clinching.

10. The method as recited in claim 1 , further comprising:
shaping a first plate into a half shell;
shaping a second plate into a half shell;
inserting at least one of a component and at least one hydraulic assembly, into at least one of the half shells;
inserting the at least one intermediate plate; and
connecting the two half shells and simultaneously manufacturing at least regional hydraulic sealing sections with the air of at least one punch riveting, clinching, soldering, welding, and gluing.

11. The method as recited in claim 10 , wherein the inserted at least one of the component and the hydraulic assembly has an oversize in relation to a formation of the half shells into which the component or the hydraulic assembly is inserted.
