  • Patent number: 8919170
    Abstract: A pot-shaped housing part, especially for a hub part of a hybrid drive. The housing part has a bottom and a wall extending axially away from the bottom, and an outer face of the wall extending at least approximately up to an outer face of the bottom, which outer face of the bottom faces away from a free edge of the wall. The wall and the bottom are configured as one piece. The outer face of the wall also has a projecting portion that projects axially beyond the outer face of the bottom and is produced from material of the wall.

  • Patent number: 8322182
    Abstract: A method for producing a pot-shaped housing part, especially for a hub part of a hybrid drive. The housing part has a bottom and a wall extending away from the bottom. An outer face of the wall extends approximately up to an outer face of the bottom, with the outer face of the bottom facing away from a free edge of the wall. The method includes the steps of clamping the radially inner zone of a blank in a workpiece holder, so that a radially outer zone of the blank directly adjoining the radially inner zone is free, and folding the radially outer zone of the blank towards and against a contact surface of the workpiece holder by means of a forming process until the outer face of the radially outer zone extends at least up to and preferably beyond the outer face of the radially inner zone.

  • Publication number: 20100129015
    Abstract: A method for producing a component made of metal, particularly for a head bearing housing of a spring strut. The component comprises a base part and a flange that extends away therefrom. The flange comprises a substantially tubular portion having a first diameter and a collar-type rim portion that adjoins the tubular portion. The free edge of the tubular portion has a second diameter that is greater than the first diameter of the tubular portion. A raw component is provided comprising a base part and a cylindrically tubular portion having a third diameter that is at least greater than the first diameter. The third diameter of the cylindrically tubular portion is reduced to the first diameter at a distance from an edge of the tubular portion by forming by means of a forming tool that is applied to the outside of the tubular portion and that acts approximately radially toward the longitudinal center axis, in such a way that the collar-type rim portion is constituted.

  • Patent number: 7232117
    Abstract: 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.
