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.
Claims11
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.
