Device for forming an oil pan and an oil pan arrangement

Abstract

A device for producing an oil pan and an oil pan arrangement are disclosed. An oil pan underside has a bottom and an all-round sidewall arranged to form a leakproof hollow space. A partition wall divides the hollow space into a suction space for forming a suction opening and an outflow space for outflow of oil along an outflow direction. The partition wall defines fluid openings for oil to flow from the suction space to the outflow space. A filter element and/or sieve element is integrated in the outflow space to filter the oil. A supporting grid is above the filter element and/or sieve element and is attached to an inside of the sidewall to fix the filter element and/or sieve element between the supporting grid and the oil pan bottom. The oil pan underside can be fixed to a corresponding wall as the upper side of the oil pan.
