Abstract

A dividing wall structure for a liquid collecting device and for a vehicle structure having a crankshaft and connecting rods. The dividing wall structure includes liquid channels and shaped portions for turning crankshaft and/or connecting-rod sections. Liquid can be forced out of the shaped portions associated liquid collecting device.

First claim

We I claim:

1 . A dividing wall structure for a liquid collecting device for a vehicle structure having a crankshaft and connecting rods, comprising
a plurality of shaped portions arranged in the dividing wall structure and configured to accommodate at least one of a turning crankshaft and connecting-rod sections; and a plurality of liquid channels arranged in the dividing wall structure, whereby liquid can be forced out of the shaped portions.

2 . The dividing wall structure according to claim 1 , wherein the liquid can be forced out of respective shaped portions via respective liquid channels.

3 . The dividing wall structure according to claim 1 , wherein at least one liquid channel connects a first shaped portion of the plurality of shaped portions to a second shaped portion of the plurality of shaped portions, such that at least one of:
liquid delivery from the first shaped portion to the second shaped portion is made possible and liquid delivery towards a liquid extraction region is made possible.

4 . The dividing wall structure according to claim 1 , wherein at least one liquid channel connects a shaped portion to a liquid extraction region, such that at least one of
liquid delivery from a first shaped portion of the plurality of shaped portions to a second shaped portion of the plurality of shaped portions is made possible and liquid delivery towards a liquid extraction region is made possible.

5 . The dividing wall structure according to claim 1 , wherein at least one liquid channel has a liquid inlet formed in one of a respective shaped portion and adjacent to the respective shaped portion.

6 . The dividing wall structure according to claim 1 , wherein at least one liquid channel has a liquid outlet formed in one of a respective shaped portion and adjacent to the respective shaped portion.

7 . The dividing wall structure according to claim 1 , wherein at least one liquid channel has a channel cross section that tapers in a direction of liquid delivery.

8 . The dividing wall structure according claim 1 , wherein a gap for receiving the liquid is formed between each of the plurality of the shaped portions and at least one of the turning crankshaft and the connecting-rod sections.

9 . The dividing wall structure according to claim 1 , wherein the shaped portions are designed in accordance with an envelope geometry of the turning of at least one of the crankshaft and the connecting-rod sections, including a clearance dimension to form a gap to receive liquid between the shaped portions and the one of the turning crankshaft and the connecting-rod sections.

10 . The dividing wall structure according to claim 8 , wherein the gap is configured such that the liquid can be forced out of the gap into the liquid channels by the turning of the at least one of the crankshaft and the connecting-rod sections.

11 . The dividing wall structure according to claim 1 , wherein the liquid can be forced out of the shaped portions into the liquid channels by the turning of the at least one of the crankshaft and the connecting-rod sections.

12 . The dividing wall structure according to claim 1 , wherein the dividing wall structure is at least one of one of:
configured to be arranged under the vehicle structure and configured to form a cover unit for the liquid collecting device.

13 . The dividing wall structure according to claim 1 , wherein the dividing wall structure is a moulding with at least one of integrated shaped portions and integrated liquid channels.

14 . A liquid collecting device for a vehicle structure comprising a crankshaft and connecting rods, having a dividing wall structure, comprising
a plurality of shaped portions arranged in the dividing wall structure and configured to accommodate at least one of a turning crankshaft and connecting-rod sections; and a plurality of liquid channels arranged in the dividing wall structure, whereby liquid can be forced out of the shaped portions.

15 . The liquid collecting device according to claim 14 , further comprising:
a liquid trough configured to receive the liquid; and a liquid extraction region, wherein the liquid extraction region is arranged substantially in a center of the liquid trough.

16 . The liquid collecting device according to claim 15 , wherein the liquid collecting device has a pump unit configured to extract the liquid from the liquid extraction region.

17 . An arrangement having a vehicle structure, which comprises a crankshaft and connecting rods, and a liquid collecting device having a dividing wall structure, comprising
a plurality of shaped portions arranged in the dividing wall structure and configured to accommodate at least one of a turning crankshaft and connecting-rod sections; and a plurality of liquid channels arranged in the dividing wall structure, whereby liquid can be forced out of the shaped portions.

18 . The dividing wall structure according to claim 2 , wherein at least one liquid connects a first shaped portion of the plurality of shaped portions to a second shaped portion of the plurality of shaped portions, such that at least one of:
liquid delivery from the first shaped portion to the second shaped portion is made possible and liquid delivery towards a liquid extraction region is made possible.

19 . The dividing wall structure according to claim 9 , wherein the gap is configured such that the liquid can be forced out of the gap into the liquid channels by the turning of the at least one of the crankshaft and the connecting-rod sections.

20 . The dividing wall structure according to claim 13 , wherein the dividing wall structure is a plastic moulding.
