发明名称 Pneumatic spring pot and method for producing same
摘要 A pneumatic spring pot has a pot wall and a bottom connected to the pot wall and also an annular flange connected, opposite the bottom, to the pot wall and intended for the fastening of, for example, a pneumatic spring concertina, the annular flange having a smaller diameter than the largest diameter of the pot wall. The bottom, pot wall and annular flange are formed in one piece with one another by sheet metal forming from a sheet part, in such a way that the annular flange is formed from the outer edge region of the sheet bar. Furthermore, a method for producing the pneumatic spring pot is described.
