Abstract

An oil sump for supplying an assembly of a motor vehicle, including: a housing including a housing frame and a closure part, such as for example a housing cover, which is joined to the housing frame; an oil accommodating space enclosed by the housing. The housing frame circumferentially surrounds the oil accommodating space; and a suction channel which extends into the oil accommodating space and includes an opening via which oil can be delivered or suctioned from the oil accommodating space through the suction channel. The suction channel is formed by the housing frame and the closure part.

First claim

The invention claimed is:

1 . An oil sump for supplying an assembly of a motor vehicle, comprising:
a housing comprising a housing frame, a housing base, and a housing cover which is joined to the housing frame; an oil accommodating space enclosed by the housing, wherein the housing frame circumferentially surrounds the oil accommodating space, the housing base closes off the oil accommodating space from below, and the housing cover closes off the oil accommodating space from above; and a suction channel which extends into the oil accommodating space and comprises an opening via which oil can be delivered or suctioned from the oil accommodating space through the suction channel, wherein the suction channel is formed by the housing frame and either the housing cover or a cover which is separate from the housing cover and the housing base, wherein an end-facing side of a circumferential wall of the housing frame together with the housing cover forms one or more oil channels, and wherein the end-facing side of the circumferential wall of the housing frame or the housing cover comprises at least one groove-shaped channel portion on its side pointing towards the housing cover or end-facing side of the circumferential wall, wherein said at least one groove-shaped channel portion is covered by the other of the housing cover and the housing frame in order to form a closed cross-section of the one or more oil channels.

2 . The oil sump according to claim 1 , wherein the circumferential wall of the housing frame exhibits an inner side and an outer side, wherein the suction channel extends from the inner side into the oil accommodating space.

3 . The oil sump according to claim 2 , wherein the housing frame or its circumferential wall comprises a connecting channel which extends from the inner side to the outer side and into which the suction channel emerges.

4 . The oil sump according to claim 1 , wherein the housing frame integrally forms the groove-shaped channel portion which is open towards the housing cover, wherein a groove-shaped channel portion formed by the housing cover closes off the channel portion of the housing frame.

5 . The oil sump according to claim 4 , wherein the channel portion of the housing frame is joined, welded or glued to the housing cover.

6 . The oil sump according to claim 1 , wherein the suction channel comprises one or more channel bends which cause(s) one or more changes in the direction of the suction channel.

7 . The oil sump according to claim 1 wherein the suction channel comprises
a channel bend which is embodied such that it causes a change in the direction of the suction channel towards the housing cover, and/or in a direction along the housing cover, and/or
a channel bend which is embodied such that it causes a change in the direction of the suction channel away from the housing cover, and/or into the connecting channel, and/or
a channel bend which is formed between a first channel bend and a second channel bend and/or in the region of a passage through which oil in the oil accommodating space can flow from one side to the other side of the suction channel.

8 . The oil sump according to claim 1 , wherein the oil sump or the housing or the housing frame comprises or integrally forms an oil filter receptacle for accommodating an oil filter, and the oil channel or one of the oil channels is connected in fluid communication with the oil filter receptacle or emerges into the oil filter receptacle.

9 . The oil sump according to claim 8 , wherein the oil sump comprises at least one supply outlet which is embodied to supply oil to an assembly, and the oil channel or one of the oil channels connects the oil filter receptacle and the at least one supply outlet in fluid communication, such that oil can be delivered from the oil filter receptacle to the at least one supply outlet through the oil channel.

10 . The oil sump according to claim 1 , wherein the oil sump or the housing cover comprises a feedback inlet or multiple feedback inlets for feeding oil from the assembly back into the oil sump and a pump inlet port for delivering fluid from the oil sump into a pump, wherein the oil channel or one of the oil channels connects the feedback inlet or one of the feedback inlets to the pump inlet port, such that oil can be delivered from the feedback inlet to the pump inlet port through the oil channel.

11 . The oil sump according to claim 1 , wherein the oil sump comprises at least one pump outlet port for delivering fluid from the pump into the oil sump, wherein the oil channel or one of the oil channels connects the pump outlet port to the oil accommodating space, such that oil can be delivered from the pump outlet port into the oil accommodating space through the oil channel.

12 . The oil sump according to claim 1 , wherein the oil sump or the housing cover comprises a feedback inlet or multiple feedback inlets for feeding oil from the assembly back into the oil sump, wherein the feedback inlet or one of the feedback inlets emerges into the oil accommodating space, such that oil can be delivered from the feedback inlet directly into the oil accommodating space or a first section or second section of the oil accommodating space.

13 . The oil sump according to claim 1 , wherein the oil sump or the housing cover comprises a feedback inlet for feeding oil from the assembly back into the oil sump, wherein the opening of the suction channel is arranged below or in a projection of the feedback inlet, and/or a deflector or a plate-shaped deflector, which is arranged between the feedback inlet and the opening is configured such that oil which flows from the feedback inlet into the oil sump flows against the deflector which prevents oil which flows from the feedback inlet into the oil sump from flowing directly onto the opening.

14 . The oil sump according to claim 1 , wherein said at least one groove-shaped channel portion is covered by at least one corresponding groove-shaped channel portion which is formed by the other of the housing cover and the housing frame.

15 . The oil sump according to claim 1 , wherein the housing frame forms a connecting channel which connects the suction channel and a pump inlet port in fluid communication, such that oil can be delivered from the suction channel to the pump via the pump inlet port.

16 . An oil delivery module which comprises an oil sump according to claim 1 and a pump, wherein a first pump inlet of the pump is connected in fluid communication with the suction channel, such that oil can be delivered from the oil accommodating space into the pump via the suction channel, and a first pump outlet of the pump is connected in fluid communication with one of the one or more oil channels formed by the end-facing side of the circumferential wall of the housing frame together with the housing cover, such that oil can be delivered from the pump into said one of the one or more oil channels.

17 . The oil sump according to claim 1 , wherein the housing frame and the housing cover are separate parts which are joined to each other by a joining connection.

18 . The oil sump according to claim 17 , wherein the joining connection comprises one of a screw connection, a material fit joining connection, a gluing connection or a welding connection.

19 . The oil sump according to claim 1 , wherein the housing frame integrally forms the housing base.
