Problems solved by technology

A disadvantage of this construction is, on the one hand, that the point-acting fastening bolts contribute to the formation of cracks and thus lead to the formation of cracks when the oil sump vibrates accordingly
On the one hand, this creates major problems during assembly, and on the other hand, it leads to an uneven distribution of the profile bridge pressure on the flange and thus increases the tendency for cracks to form in the area of ​​the oil sump that is loaded with higher pressure
In addition, uneven positioning of the oil sump flange on the crankcase-side flange can have a negative effect on the sealing effect of the intermediate seal

Embodiment Construction

[0017] figure 1 A sectional view perpendicular to the edge of a surrounding oil sump for an oil sump of a truck internal combustion engine is shown in a simplified partial view. In an oil bath 1 made of sheet steel, a round steel metal part 2 , for example a round steel, is formed in a form-fitting manner. On the side of the oil sump edge 3 facing away from the metal part 2 is an elastic seal 4 which is surrounded by the oil sump edge 3 and which is located between the crankcase and the oil sump edge 3 when the oil sump 1 is positioned on the crankcase 5 .

[0018] For fixing the oil sump 1 on the crankcase 5 there is an L-shaped fastening claw 6, which bears against the metal part 2 with its first leg 6a tangentially in the drawing, but rectilinearly when viewed into the drawing. The attachment of the fastening claw 6 to the crankcase 5 is effected by means of through-bolts 7 , which pass through the second leg 6 b and are anchored in the crankcase 3 via threaded holes (not...

Abstract

The invention relates to an oil sump and a processing method. The oil sump is used 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.

Description

technical field [0001] The invention relates to an oil sump for use on an internal combustion engine or a retarder according to the preamble of claim 1 . Background technique [0002] Internal combustion engines which are not only installed in motor vehicles but also run stationary usually have an oil sump which is arranged on the crankcase in the region of the crankshaft and surrounds the crankshaft. This oil sump is also used on the reducer. It is also common to have a top basin for such oil sumps for sound insulation. Such pools are often made of sheet steel, which takes the shape of the pool in a deep-drawing process. [0003] Such pools are under very high acceleration forces due to the vibrations generated by the internal combustion engine or the vehicle in which the internal combustion engine runs. Accelerations of up to 50 times the acceleration due to gravity have been measured on the oil sump of trucks. This necessitates special constructional measures especial...
