Abstract
An oil sump for use in internal combustion engines or transmissions, where the oil sump consists of sheet metal shaped by deep drawing and has a reinforced edge, by means of which it rests, in its mounted state, in the internal combustion engine or the transmission with a seal positioned between them. The reinforcement consists of at least one separate metal part, which is mounted on the edge of the oil sump by positive locking and/or nonpositive locking with deformation of the edge of the oil sump.
Claims11
An oil sump for use in internal combustion engines or transmissions, comprising a wall made of sheet metal shaped by deep drawing and having a reinforced edge for resting in its mounted state, on the internal combustion engine or the transmission;
- at least one separate metal part (2) mounted on said edge (3) of the oil sump by one of positive locking and nonpositive locking with deformation of the edge (3) of the oil sump.
A method of producing an oil sump for use in internal combustion engines or transmissions, said oil sump comprising of sheet metal shaped by deep drawing and having a reinforced edge, for resting, in its mounted state, on the internal combustion engine or the transmission with a seal positioned between them, said method comprising:
- preshaping said oil sump (1) from sheet metal in at least one deep-drawing operation;
- producing in an operation that is separate from said deep-drawing operation, at least one metal part (2) in a shaping production process, said metal part (2) being shaped in such a way that it corresponds to at least part of the final shape of the edge of the oil sump (1);
- placing the metal part (2) and the preshaped oil sump (1) into a die;
- and in an additional shaping process shaping the edge of the oil sump (1) around the metal part (2) so as to result in one of a nonpositive connection and a positive connection between the oil sump (1) and the metal part (2).
