Description

Stabilizer mounting structure

The present invention relates to a stabilizer mounting structure that is mounted on a subframe of a vehicle by a fixing bracket, for example.

Conventionally, a stabilizer is inserted by inserting a torsion portion at an intermediate portion in a longitudinal direction into a rubber bush formed in a substantially cylindrical shape, and bolting the bush to a subframe with a fixing bracket (bracket piece). It is fixed to the vehicle body (see, for example, Patent Document 1).

Both ends of the stabilizer of Patent Document 1 are connected to a pair of dampers that support the left and right front wheels of the automobile. The left and right end portions of the middle portion (torsion portion) of the stabilizer are the upper surface portion of the sub-frame having a hollow cross-section structure in which the upper surface portion and the lower surface portion are joined, and the concave portion of the fixing bracket bolted to the upper surface portion. It is attached so as to be sandwiched between the two.

Each fixing bracket is made of a rectangular metal plate member that is long in the front-rear direction in plan view, and has bolt holes formed at both front and rear ends. The bolt holes on the front side are fastened together with bolts and nuts in order to fasten the engine mount bracket to the upper surface of the subframe. The bolt hole on the rear side is fixed with a dedicated bolt for fastening the fixing bracket to the lower surface portion of the subframe.

In the stabilizer mounting structure described in Patent Document 1, rigidity is improved by fastening the mounting bracket to the subframe together with the mounting bracket with a bolt for mounting the mounting bracket to the upper surface of the subframe. ing.

However, in the stabilizer mounting structure described in Patent Document 1, the mounting bracket provided on the upper surface portion of the subframe and the fixing bracket provided on the lower surface portion are bolts inserted into a collar disposed in the subframe. It is fastened together with the subframe. In such a stabilizer mounting structure, there is a problem that the number of parts and assembly man-hours increase due to the presence of the collar.

In addition to this, as a structure for mounting the stabilizer to the subframe using the mounting bracket, there is a structure in which a reinforcing patch part is interposed between the mounting bracket and the subframe.

When a patch part is attached between the subframe and the mounting bracket, there is a problem that the center of the stabilizer is displaced in the upward direction because the patch part is on the subframe.
For this reason, there has been a demand for a stabilizer mounting structure in which the rigidity of the stabilizer mounting portion is improved.

Therefore, an object of the present invention is to provide a stabilizer mounting structure capable of improving the rigidity of the stabilizer mounting portion.

As means for solving the above problems, a stabilizer mounting structure according to the present invention includes a stabilizer, a subframe having a plate-like member extending in the vehicle width direction, and a bracket for fixing the stabilizer to the plate-like member. The bracket includes: a stabilizer bracket attached to a surface of the plate-like member on the stabilizer side; and a fixing bracket attached to a surface of the plate-like member opposite to the stabilizer, the fixing bracket Comprises a support part for supporting the stabilizer and an extension part extending from one end of the support part and joined to the front end or the rear end of the plate-like member.

According to such a structure, the mounting structure of the stabilizer is such that the extension portion extending from one end of the support portion supporting the stabilizer is joined to the front end or the rear end of the plate-like member, so that the fixing bracket is plate-like. It can be firmly fixed to the member. For this reason, the fixing bracket can improve the rigidity of the mounting portion of the stabilizer by transmitting the load applied to the fixing bracket to the plate-like member of the subframe and dispersing it.

Moreover, it is preferable that the extension portion becomes wider as it goes from the support portion to the joint portion with the plate-like member.

According to such a configuration, the extension portion of the fixing bracket is formed to have a width that increases from the holding portion toward the joint portion with the plate-like member, thereby dispersing the load applied to the extension portion. Can be communicated to the joint.

Further, the plate-like member has a widened portion formed to widen in the vehicle front-rear direction on the vehicle rear side, and the fixing bracket has a bent portion between the support portion and the extension portion. It is preferable that the support portion is disposed so as to extend in the vehicle front-rear direction, and the joint portion is joined to the widened portion.

According to such a configuration, the fixing bracket is joined to the widened portion in which the width in the front-rear direction of the subframe is gradually enlarged, so that the widened portion and the plate-like member are connected to the vehicle width. It is joined in a state of overlapping when viewed from the direction. For this reason, the fixing bracket can reliably transmit the load applied in the vertical direction from the stabilizer to the subframe via the fixing bracket during traveling of the vehicle.

Further, it is preferable that the plate-like member has a closed cross-sectional structure with another plate-like member arranged facing the plate-like member.

According to such a configuration, the strength of the sub-frame is improved by forming a closed cross-sectional structure with the plate-like member and the other plate-like member arranged facing the plate-like member. Yes. For this reason, when a load is applied to the subframe, the load can be received by the entire subframe having a closed cross-sectional structure.

As shown in FIG. 6, the curved portion 7o is a portion formed in a substantially arc shape in plan view, and is formed on the side surface of the extension portion 7b.

≪Action≫
Next, the operation of the stabilizer mounting structure according to this embodiment will be described.
As shown in FIGS. 5 and 7, the nut 6 allows the fixing bracket 7, the upper plate member 14, and the stabilizer bracket 4 to be in a state where the convex portion 6 b is engaged with the

concave portions

7 m and 7 n of the fixing bracket 7. Since it is interposed and fastened to the bolt 5, it can be firmly fastened without loosening. The nut 6 has a larger outer diameter than the outer diameter of the head of the bolt 5 or a general-purpose nut, so that moment stress generated by an external force can be reduced.

Thus, the nut 6 has a large outer diameter, and is firmly fastened by the bolt 5 with the convex portion 6b engaged with the

concave portions

7m and 7n. Therefore, the nut 6 is subjected to vibration or input load (external force) while the automobile is running. It can prevent loosening. Further, a cylindrical member such as a collar is not interposed between the bolt 5 and the nut 6. Therefore, the cost can be reduced by reducing the number of parts and the number of assembling steps as much as there is no color or the like.

In this way, the stabilizer bracket 4 in which the stabilizer 2 is held on the upper surface of the upper plate-like member 14 with the stabilizer bush 3 interposed therebetween is provided on the lower surface side of the attached upper plate-like member 14. By fixing in a state where the support portions 7a are overlapped so as to be addressed, the stabilizer attachment portion 14g is reinforced and the rigidity against external force is improved.

In addition, the fixing bracket 7 functions as a reinforcing patch member by being fastened to the ceiling surface on the opposite side of the stabilizer attaching portion 14g of the upper plate-like member 14 to which the stabilizer 2 is attached. The fastening strength and durability of the fastening surface of 1 can be improved.

Further, the support portion 7a of the fixing bracket 7 that supports the stabilizer 2 is such that the joint portion 7c at the tip of the extension portion 7b extending from the support portion 7a is the widened portion at the rear end of the upper plate member 14 (plate member). The fixing bracket 7 can be firmly fixed to the upper plate member 14 by being joined to the inner wall surface of 14f.

Further, as shown in FIG. 5, the widened portion 14f of the upper plate-like member 14 to which the joint portion 7c is joined is an inner wall surface of a bent portion 14b that is bent downward in an L shape with respect to the ceiling surface. Therefore, a ridge line is formed at the upper end of the widened portion 14f and the rigidity is increased. For this reason, the widened portion 14f has a strong supporting force for supporting the joint portion 7c of the fixing bracket 7 and can firmly hold the joint portion 7c.

Further, as shown in FIG. 2, the extension 7b extending from the support portion 7a of the fixing bracket 7 toward the center side in the oblique vehicle width direction is formed such that the width increases from the support portion 7a toward the joint portion 7c on the front end side. Therefore, the load applied in the direction from the support portion 7a to the joint portion 7c can be dispersed and transmitted to the joint portion 7c.

The extension portion 7b extends in a direction orthogonal to the inner wall surface of the widened portion 14f formed obliquely in the left-right direction in plan view, and the joint portion 7c at the tip of the extension portion 7b is connected to the upper plate. It arrange | positions and is joined in the state contact | abutted to the inner wall face (refer FIG.4, FIG.5 and FIG.7) of the wide part 14f of the shaped member 14. FIG.

For this reason, an external force in the vehicle width direction (arrows A and B) is applied to the stabilizer 2, and a load in the vehicle width direction is applied to the fixing bracket 7 via the stabilizer bush 3, the stabilizer bracket 4, and the bolt 5. Even if the joint portion 7c is joined to the inner wall surface of the widened portion 14f (see FIGS. 4, 5, and 7), the load applied to the fixing bracket 7 is received by the widened portion 14f and It can be distributed throughout the frame 1.
When the stabilizer 2 is twisted and an external force in the vertical direction is applied to the bracket mounting surface of the stabilizer mounting portion 14g, the bracket mounting surface is moved alone by the external force, but is fixed to the lower surface of the stabilizer mounting portion 14g. By connecting the bracket 7 for use, the surface rigidity of the left and right stabilizer mounting portions 14g can be improved.
In this way, the subframe 1 has the left and right stabilizer attachment portions 14g to which the stabilizer 2 is attached and the rigidity of the subframe 1 as a whole.

As a result, the stabilizer bush 3, the stabilizer bracket 4, and the fixing bracket 7 that support the stabilizer 2 are prevented from moving in the vehicle width direction and can be prevented from being displaced in the axial direction by an external force.
In addition, the subframe 1 is not significantly changed in shape only by forming the stabilizer mounting portion 14g for installing the fixing bracket 7 and the widened portion 14f to which the joint portion 7c is joined. The cost increase due to the shape change can be suppressed.

Moreover, since the stabilizer bush 3, the stabilizer bracket 4, the bolt 5, the nut 6 and the fixing bracket 7 for fixing the stabilizer 2 to the subframe 1 can share each component arranged on the left and right of the subframe 1, Cost can be reduced.
