Description

  The present invention relates to an improvement of a stabilizer bracket.

  Generally, a shock absorber is interposed between the left and right front wheels of the automobile and the vehicle body, and the shock due to road surface unevenness is prevented from being transmitted to the vehicle body by these shock absorbers. Further, the two shock absorbers are connected by a stabilizer, and the stabilizer is a stabilizer bar that is twisted when the left and right front wheels move in opposite phases to generate a predetermined reaction force, both ends of the stabilizer bar, Left and right stabilizer links interposed between the shock absorber and the vehicle body roll can be suppressed and the posture of the vehicle body can be stabilized. The stabilizer bracket is attached to each shock absorber and is used to connect the shock absorber and the stabilizer link.

  For example, as shown in FIG. 4, the stabilizer bracket A1 disclosed in Patent Document 1 includes a rectangular plate-like connecting portion 100 having four corners welded to the outer peripheral surface of the outer cylinder T of the shock absorber, and the connecting portion 100. And a plate-like mounting portion 200 which is erected along the one side end portion and is disposed along the axial direction (vertical direction in FIG. 4) of the outer cylinder T. A stabilizer is provided at the approximate center of the mounting portion 200. A hole 22 for attachment is formed. And although not shown in figure, the upper end part of the stabilizer link is connected with the said hole 22, and the one side edge part of the stabilizer bar is connected with the lower end part of this stabilizer link.

JP-A-10-119527

  Here, the outer cylinder T of the shock absorber to which the conventional stabilizer bracket A1 is attached is connected to the spring seat S that supports the lower end of the suspension spring that elastically supports the vehicle body, and the knuckle that supports the wheel. The knuckle bracket N is attached, and the stabilizer bracket A1 is disposed between the spring seat S and the knuckle bracket N. In such a shock absorber, a sufficient space for welding the connecting portion 100 of the stabilizer bracket A1 to the outer cylinder T of the shock absorber cannot be secured because the spring seat S and the knuckle bracket N are close to each other. However, there is a case where it is desired to maintain the position of the hole 22 for attaching the stabilizer above the knuckle bracket N.

  However, if the connecting portion 100 is welded to both the outer cylinder T and the knuckle bracket N, when the shock is applied to the shock absorber, the outer cylinder T and the knuckle bracket N are deformed differently, so that the welding strength may be reduced. .

  Further, as shown in FIG. 5, the connecting portion 100 of the stabilizer bracket A2 is welded to the knuckle bracket N, the attachment portion 200 is extended to the upper side of the knuckle bracket N, and a hole 22 for attaching the stabilizer is formed in the extended portion 201. A method of forming is conceivable. However, in the case of the stabilizer bracket A2, the stabilizer mounting hole 22 is in the range where the stabilizer mounting hole 22 deviates from the welding section (the section from the welding upper end to the welding lower end) Y of the connecting portion 100, and the hole 22 is formed. There is a possibility that the strength of the extended portion 201 is insufficient.

  Therefore, an object of the present invention is to suppress the shortage of the strength of the portion where the hole is formed in the mounting portion even if the stabilizer mounting hole is displaced in the axial direction from the welding section of the connecting portion. It is to provide a possible stabilizer bracket.

  Means for solving the above-mentioned problems include a connecting part welded and fixed to the outer cylinder of the shock absorber or the outer surface of the cylindrical body attached to the outer cylinder of the shock absorber, and a hole for attaching the stabilizer connected to the connecting part. In the stabilizer bracket including the formed attachment portion, the connecting portion is welded in a standing state on the outer peripheral surface of the outer cylinder or the cylindrical body, and is along the axial direction of the outer cylinder or the cylindrical body. An axially connecting piece disposed; and the attachment portion extends from the axially connecting piece to the axially one side of the outer cylinder or the cylindrical body, and the anti-cushioner side of the extending piece And an attachment piece extending inclined from the end, and the hole is formed in the attachment piece.

  According to the present invention, even if the hole for attaching the stabilizer is shifted in the axial direction from the welding range of the connecting portion, it is possible to suppress the lack of strength of the portion where the hole is formed in the attaching portion. Become.
