Description

The invention relates to a multi-part housing for a Machine, especially for an internal combustion engine, with one at least indirectly on a main section attached trough-shaped collecting section for one in the Housing existing fluid.

Such a housing is known from EP 0 952 313 A2. The case described there is Housing of an internal combustion engine. On the one hand, it includes a Crankcase and on the other hand an oil pan, which on the Bottom of the crankcase is attached. The oil pan again consists of a very thin-walled shell that itself has little inherent stability. Around the shell is arranged around a stable latticework, which is attached to the crankcase with a frame. On a so-called oil slicer is molded onto the shell, with which the swirling of the oil in the oil pan can be reduced can.

From DE 196 44 645 A1 an oil pan is known, in which various functional elements of the internal combustion engine are integrated.

The disadvantage of the known housings is that they either build relatively difficult or integrate the Functional elements in the housing is complex.

This results in the present invention Task, the lightest possible housing for a machine to create in the required for the machine Functional elements nevertheless safely and easily housed can be.

This task is the case of a housing of the type mentioned Kind of solved by having at least one Functional frame, which on the main portion of the Housing is at least indirectly attached, and that the Functional frame has at least one holding section, which protrudes into the space enclosed by the collecting section and on the at least one functional element of the machine can be attached.

This task is the case of a housing of the type mentioned Art also solved in that the housing at least one Functional frame, which on the main portion of the Housing is at least indirectly attached and that on Functional frame at least one functional element of the Machine is arranged in one piece.

Advantages of the invention

The present invention has the advantage that the trough-shaped collecting section can be built extremely easily can, since no functional elements are attached to it have to. The collecting section serves the multi-part Ultimately, the housing only adds to the main section to be fluid-tight. The attachment of the for the Operation of the machine required functional elements instead of the functional frame and the one on it provided holding sections.

The functional elements can be installed in the housing pre-assembled on the holding sections of the functional frame become. Then the functional frame on Main section fastened and the trough-shaped Collection section on the functional framework and on this attached functional elements are "put on". It is also possible to assemble the collecting section on Function frame. The assembly of the functional elements will this considerably simplified. At the same time it builds Housing very light, since the collecting section is weight and cannot be designed with rigidity optimization.

The multi-part housing is particularly suitable for one Internal combustion engine or for a transmission. By both There are moving parts available through machines an oil lubrication can be lubricated with an oil sump. The Oil is collected safely in the collection section.

Advantageous developments of the invention are in Subclaims specified.

Great flexibility in the attachment of Functional elements is achieved in that the Holding section a rail, plate or bracket includes.

The multi-part housing and the case are particularly suitable this intended functional frame for attachment for example a shaft of a pulley, one Filter housing, an oil filter, an oil pump, one Oil suction pipe, an oil return and / or an oil slicer.

The functional elements can also be made in one piece on Functional frame to be arranged. Under one piece is understood that the functional element is either integrally formed with the functional frame or that at least one component of a functional element is integrated in the functional frame. An integration A functional element can consist, for example, in that a Part of the functional frame is designed as a sieve part with the contaminants from the fluid in the machine can be filtered out. The integration of one Component of a functional element can, for example exist that part of the functional framework as a housing is formed in the other components of the Functional elements can be used.

The one-piece arrangement of the functional elements on Functional frame has the advantage that the number of required components is reduced. Hereby the Assembly and logistics effort reduced and the multi-part Housing cheaper overall.

The multi-part housing and the case are particularly suitable this intended functional frame for the one-piece Arrangement of, for example, a shaft of a pulley, a filter housing, an oil filter, an oil pump, one Oil suction pipe, an oil return and / or an oil slicer.

When the collection section is inserted into the functional frame , this has the advantage that the collection section through the functional frame on the main section of the multi-part Housing is set. Has the same advantage too the housing in which the collecting section with the Functional frame is welded or overmolded. The However, fluid sealing is even more reliable here.

To the collection section itself, which is not very stable Being able to protect damage during operation can on the outside at least in some areas Coating from a soft, preferably rubber-elastic, more preferably elastomeric, Wear material. Such a coating can also have a noise-dampening effect, what that Operating noise of the machine reduced.

To increase the protective effect of the coating and also The coating can be used to increase the sound damping effect be provided with spikes or knobs on the outside.

Basically, the housing according to the invention is not only on the use of a single functional framework limited. It is also possible to use a second one or possibly a variety of Functional frame attached to the main section of the housing are at least indirectly attached and which each have at least one holding section which in the from Collected section protrudes from the room attached at least one functional element of the machine can be. The functional elements can also be in one piece be arranged on the functional frame. That's the way it is for example, conceivably that functionally belong together Functional elements on a common Function frames are attached. This can reduce the effort reduced in manufacturing and manufacturing quality increase.

The invention also relates to a multi-part housing for a machine, especially for an internal combustion engine, with a functional element on which at least one Functional frame is arranged in one piece, which on a Main section of a housing at least indirectly is attached, at least on the main portion indirectly a trough-shaped collecting section for one in the Housing existing fluid is attached.
