Description

[Detailed Description of the Invention] This invention relates to an improvement of a lateral rod support bracket for an automobile.

A support bracket that pivotally supports the body side end of a lateral rod of an automobile supports the lateral rod via a pin in the longitudinal direction of the automobile by front and rear walls arranged in parallel and apart from each other in the longitudinal direction of the automobile.

If the rigidity of such a lateral rod support bracket is insufficient, conventionally a reinforcing plate has been attached to the outside to increase the rigidity in order to increase differential noise, but this is not always sufficient and also increases the weight of the automobile. This was accompanied by the inconvenience of causing damage to the appearance.

For example, as a general reinforcing structure,
-11715 is known.

This is a structure that connects the rear side member to the rear cross member, and a bulkhead is used as the connection part.

However, even if the structure shown in this prior art is adopted for the lateral rod support bracket, it is not possible to improve the rigidity of the vehicle in the vertical and lateral directions, and ultimately it is not possible to reduce differential noise. It was something.

This idea was made to solve the above-mentioned conventional disadvantages, and by using a bulkhead made of less material, it can effectively increase rigidity and reduce differential noise without increasing weight or spoiling the appearance. It is an object of the present invention to provide a lateral rod support bracket for an automobile.

This invention is based on a lateral rod support bracket for an automobile that pivots the end of a lateral rod via a pin in the longitudinal direction of the automobile, in which the lateral rod is placed between the front and rear walls of the support bracket that supports the pin in the vicinity of the pin. The above object is distantly achieved by arranging bulkheads obliquely upward in the horizontal direction and outwardly from the side ends, respectively, and connecting these bulkheads to the front and rear walls of the support bracket by welding.

Embodiments of the present invention will be described below with reference to the drawings.

Front and rear walls 5 and 6 of a support bracket 4 that swingably supports the body side end 2 of the lateral rod 1 via a pin 3
are integrally connected in the front-rear direction by an inclined wall 9 and an outer wall 10, leaving an opening 8 on the lower side of the hole 7 through which the pin 3 is inserted and on the center side of the body.

A bulkhead 11 is arranged so as to extend outward from the central end 8A of the opening 8 in a substantially horizontal direction.

This bulkhead 11 has a downward bent portion 1 in the front-rear direction.
2, and the front and rear walls 5 and 6 are provided at this bent portion 12.
are welded to connect them.

Further, the upper part of the horizontal bulkhead 11 has a reference numeral 11.
As shown by A, another bulkhead is attached obliquely upward and outward from the central end 8A of the opening 8.

This bulkhead IIA similarly includes a downwardly bent portion 12A in the front-rear direction, and the front and rear walls 5 and 6 are welded together at this bent portion 12A.

In the figure, reference numeral 13 indicates a notch for escaping the upper part of the body side end portion 2, and IOA indicates a reinforcing plate.

In the above embodiment, the bulkhead 11 is close to directly above the pin 3 for supporting the lateral rod 1, and the front and rear walls 5 and 6 are
Since they are connected to form a closed cross section, the rigidity is greatly increased.

In particular, since the bulkhead is mounted not only horizontally but also diagonally in three directions, the rigidity of the lateral rod support brackets 1 to 1 can be increased against vibrations in the vertical and horizontal directions of the vehicle.

Incidentally, the bulkhead 11 may be formed with a bent piece 14 for welding to the inclined wall 9 and the outer wall 10, as shown in FIG.

By welding this bent piece 14, the rigidity can be further increased.

The present invention provides a lateral rod support bracket for an automobile that pivotally supports the end of a lateral rod via a pin in the longitudinal direction of the automobile as described above, between the front and rear walls of the support bracket that supports the front and rear of the pin in the vicinity of the pin. The bulkheads are arranged approximately horizontally and diagonally upward from the center end of the lateral rod, respectively, and these bulkheads are connected to the front and rear walls of the support bracket by welding. This has the excellent effect of increasing the rigidity of the support bracket, reducing the transmission of differential noise, and being able to be constructed at low cost without damaging the appearance.

According to the applicant's experiments, the longitudinal vibration of the body-side end of the lateral rod is as follows: In the case of the bracket shown in FIG. 3, the results are as shown by the solid line A in FIG. 3, and when two bulkheads are attached as in this example, the results are shown by the chain line B, and it was confirmed that the vibration level was significantly reduced.
