Load-bearing structural

Abstract

Load-bearing structural component (1) in particular of a motor vehicle including a strut-dome (2) to hold the strut and an engine support (3) to fasten an engine wherein the load-bearing structural component (1) is formed in one-piece as a single part.

Claims

1. Load-bearing structural component for a motor vehicle comprising a strut-dome for holding of a strut and an engine support to fasten an engine wherein the load-bearing structural component is formed as one-piece, and the load-bearing structural component having grooves to increase the stiffness.

2. Load-bearing structural component according to claim 1, wherein the engine support includes a water-tank support.

3. Load-bearing structural component according to claim 1, wherein the load-bearing structural component is a cast part.

4. Load-bearing structural component according to claim 1, wherein the load-bearing structural component is made of light metal alloy.

5. Load-bearing structural component according to claim 1, wherein the load-bearing structural component has reinforcing ribs in a transition area between the strut-dome and the engine support.

6. Load-bearing structural component according to claim 1, wherein reinforcing ribs are arranged on the bottom side of the engine support.

7. Load-bearing structural component according to claim 1, wherein the grooves are in the engine support and run vertically.

8. Load-bearing structural component according to claim 7, wherein the grooves are arranged on the engine support.

9. Load-bearing structural component according to claim 1, wherein the load-bearing structural component has integrated mounting points.

10. A load bearing structural component for a motor vehicle comprising: an integrally formed cast member including all of the following: a raised dome having a generally flat upper surface; a plurality of mounting structures on the flat surface of the dome having increased thicknesses configured to receive a strut; an engine support portion of lesser height than the dome; a wall of the dome transitioning between the flat upper surface of the dome and the engine support portion; at least one support on the wall configure to mount a water tank; and reinforcing ribs on an underside of the engine support portion.

Description

(1) An exemplary embodiment of the invention is described by way of the Figures, the invention not being restricted to only the exemplary embodiment, in which:

(2) FIG. 1 shows a three-dimensional view of the invented load-bearing structural component from the upper side and

(3) FIG. 2 shows a three-dimensional view of the invented load-bearing structural component from the bottom side.

(4) FIG. 1 shows a three-dimensional view of the invented load-bearing structural component (1) from the upper side. The load-bearing structural component (1) includes a strut-dome (2) which holds the strut (not shown) and an engine support (3) to mount an engine on it. The load-bearing structural component (1) is a single part that means the engine support (3) and the strut-dome is one piece.

(5) The strut-dome (2) has a suspension bracket (5) which has fixing points (8) to assembly the strut. Because of the thin wall thickness of the load-bearing structural component (1) are the fixing points (8) in their cross section thicker to get enough strength.

(6) The load-bearing structural component (1) is a cast part. Preferably, the load-bearing structural component (1) is made of light metal alloy because of the weight reducing and the avoiding of corrosion; to prefer is aluminum- or also magnesium alloy but others are also possible.

(7) As shown in FIG. 1 the load-bearing structural component (1) has reinforcing ribs (7) to support respectively to reinforce the area with the highest load which is given by the geometry of the load-bearing structural component (1). The reinforcing ribs (7) are placed between the strut-dome (2) and the engine support (3) to reinforce the transition area.

(8) A further possibility to reinforce the load-bearing structural component (1) is the arrangement of grooves (6) in the cast part. These moulded grooves (6) respectively channels generate a kind of ribbing in the load-bearing structural component (1) which increase the stiffness of the part. Preferably are the grooves (6) arranged in the engine support (3).

(9) The load-bearing structural component (1) has mounting points (9),(10) for the assembly of further motor parts like a water-tank and others on it. The benefit of the mounting points (9) is that they are included in the cast part, preferably to fix the additional motor parts directly on the load-bearing structural component (1) without further required sheets.

(10) FIG. 2 shows the bottom of the load-bearing structural component (1). The reinforcing ribs (7) support the load behavior of the load-bearing structural component (1) especially at the engine support (3). The load becomes a better distribution on the engine support (3). Furthermore there are also mounting points (7) placed to fix motor parts.
