Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a suspension device for a vehicle.

(Prior Art) Generally, a suspension device for a vehicle includes a shock absorber (for example, a shock absorber) for damping transmission of vibration from a wheel side to a vehicle body side, and a stabilizer for absorbing relative displacement of left and right wheels. Etc. are attached (see, for example, Japanese Utility Model Laid-Open No. 60-47611). In the case of the known example, the lower end of the shock absorber is supported by the knuckle for supporting the wheel, while the end of the stabilizer is supported by the upper surface of the suspension lower arm via a link for control.

(Problems to be Solved by the Invention) In recent years, as an attempt to strengthen the support rigidity of a shock absorber, it has been attempted to support the lower end of the shock absorber to a suspension lower arm. On the other hand, as a suspension device, a double wishbone type is often used, but in this case, an upper arm or the like is arranged above the suspension lower arm, so that the upper surface of the suspension lower arm is The support for the stabilizer control link will be structurally difficult. However, if the stabilizer control link is supported on the lower surface of the suspension lower arm, if the ground clearance is to be secured sufficiently, the link length will be limited and the stabilizer control will be insufficient. If the link length is to be secured sufficiently, there is a possibility that the ground clearance cannot be secured.

The present invention has been made in view of the above points, and an object thereof is to obtain an appropriate support structure for a stabilizer control link while enhancing the support rigidity of a shock absorber.

(Means for Solving the Problems) In the present invention, as means for solving the above problems, a pair of support flanges facing each other are provided on the upper surface of the suspension lower arm so as to project between the support flanges. A first support member for supporting the lower end portion and a second support member for supporting the stabilizer control link are installed, and the stabilizer control link supported by the second support member is directed downward on the suspension lower arm. A through hole that should be projected is formed.

(Operation) In the present invention, the following operations can be obtained by the above means.

That is, the lower end of the shock absorber is supported by the first support member installed between the pair of support flanges projecting from the suspension lower arm and the second support member installed between the support flanges. The supported stabilizer control link is made to project downward through a through hole formed in the suspension lower arm.

(Effect of the Invention) According to the present invention, on the upper surface of the suspension lower arm,
Since a pair of support flanges facing each other is provided so as to support the lower end portion of the shock absorber with respect to the first support member provided between the support flanges, the support rigidity of the shock absorber is significantly improved. There is a practical effect that will happen.

Further, since the stabilizer control link is supported by the second support member provided between the support flanges, and the stabilizer control link is made to project downward through the through hole formed in the suspension lower arm. By using the support flange for supporting the shock absorber, the stabilizer is arranged on the lower surface side of the suspension lower arm to prevent a decrease in ground clearance, and further, the stabilizer control link can have a sufficient length.

(Embodiment) Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

The suspension device of the present embodiment is provided on the front side of an automobile, and includes a suspension lower arm 1 interposed between a front wheel (not shown) and a vehicle body.

As shown in FIG. 1, the suspension lower arm 1 has a vehicle width direction extending portion 1d having a wheel side fixed end 1a supported on the wheel side and a vehicle body side fixed end 1b supported on the vehicle body side,
A longitudinally extending portion 1e extending rearward from the vehicle body side fixed end 1b and having a vehicle body side fixed end 1c supported at the vehicle body side at the rear end thereof.
And a substantially L-shaped arm member.

A pair of support flanges 2, 2 are integrally formed on the upper surface of the suspension lower arm 1 extending in the vehicle width direction 1d so as to project integrally, and a shock acting as a shock absorber is provided between the support flanges 2, 2. A first support member 4 for supporting the lower end of the absorber 3 and a second support member 6 for supporting the upper end of the stabilizer control link 5 are installed in parallel with each other (see FIGS. 2 and 3). See figure). In the case of this embodiment, the second supporting member 6 is located closer to the vehicle body sensor than the first supporting member 4. The shock absorber 3 serves to buffer the transmission of vibration from the wheel side to the vehicle body side, and a known one is used. The link 5 supports the end portion of the stabilizer 7 for absorbing the relative displacement of the left and right wheels, and has a structure described in detail later.

A through hole 8 is formed in the extension portion 1d in the vehicle width direction of the suspension lower arm 1 so that the link 5 supported by the second support member 6 projects downward. That is, the link 5 is projected downward through the through hole 8 while the upper end of the link 5 is supported by the second support member 6, and the lower end of the link 5 supports the end of the stabilizer 7. It is configured like this. The upper end of the link 5 and the second support member 6 are swingably connected via a pillow ball 9, while the lower end of the link 5 and the end of the stabilizer 7 are connected via a ball joint 10. It is swingably connected.

With the above configuration, the shock absorber 3
Since the support rigidity of the lower end is significantly improved, and the upper end of the link 5 is supported by the second support member 6 located above the suspension lower arm 1, the length of the link 5 is increased. It is also possible to prevent a decrease in ground clearance due to the stabilizer 7 being arranged below the suspension lower arm 1 while sufficiently securing the height.

It is needless to say that the present invention is not limited to the configuration of the above-described embodiment and can be appropriately modified in design without departing from the gist of the invention.
