Description

[Detailed description of the invention] (Field of industrial application) This invention is a suspension support for fixing the upper end of the absorber rod of a shock absorber used as a suspension system for vehicles such as automobiles to the body of the vehicle. It's about structure.

(Prior Art) A damping force adjustable shock absorber has a shock absorber rod. A piston is provided at the lower end of this shock absorber rod, and this piston is housed in an oil-containing cylinder that is attached to the wheel side of the car, and the inside of this cylinder is divided into upper and lower parts. There is.
The piston is equipped with a suitable number of orifices that pass through the piston in the vertical direction, and when the absorber rod moves back and forth with respect to the cylinder, a damping force is generated by the resistance of the oil flowing through the orifices. ing. A control rod is rotatably provided at the axial center of the shock absorber rod, and an actuator for rotating the control rod is attached to the upper part of the shock absorber rod. When the actuator operates to rotate the control rod, oil in the cylinder moves through a passage other than the orifice provided in the piston, thereby adjusting the damping force generated by the piston.

By the way, to explain how to attach a conventional actuator to a shock absorber rod with reference to FIGS. 1 and 2, the suspension support 2 consists of an annular elastic body 2a and a ring-shaped elastic body 2a, which is fixed to the outer peripheral surface by baking or the like. The upper outer flange member 2b, the lower outer flange member 2c, and the inner flange member 2d form a ring body as a whole. The suspension support 2 is inserted into a mounting hole 3 provided in the vehicle body 1, and is attached to the vehicle body 1 with bolts 4 and nuts 5 at the outer edges of the upper outer flange member 2b and the lower outer flange member 2c. The inner flange member 2d of the suspension support 2 has a cylindrical shape, and its upper end forms an outward flange, on which the bottom surface 6 of the cylindrical bracket 6 is attached.
A is placed. The upper end of the absorber rod 7 of a shock absorber (not shown) is a threaded portion 7a, and the threaded portion 7a is connected to an inner flange member 2d.
Insertion holes 9 provided inside and on the bottom surface 6a of the bracket 6
The bracket 6 is attached to the flange of the inner flange member 2d by a nut 8 attached to the threaded portion 7a of the absorber rod 7.
The insertion hole 9 is approximately D-shaped, and the threaded portion 7a of the absorber rod 7 is also approximately D-shaped. Therefore, when the absorber rod 7 rotates about its axis, the bracket 6 also rotates. The upper end of the bracket 6 is an outward flange 6b,
An actuator 10 is attached to this flange portion 6b with bolts or the like (not shown). 13 is a lead wire of the actuator 10. Further, 14 is a control rod rotated by the actuator 10.

In the conventional suspension support 2 described above, when the absorber rod 7 rotates about its axis while the vehicle is running, the D-shaped threaded portion 7a of the absorber rod 7 and the D-shaped insertion hole 9 of the bracket 6 are used. The actuator 10 rotates together with the bracket 6. As a result, the lead wire 13 wraps around the actuator 10 and breaks, causing the actuator 1
0 functions may be impaired.

(Purpose of the invention) The purpose of this invention is to provide a suspension support that restricts the rotation of the absorber rod around its axis and prevents the lead wire attached to the actuator from wrapping around the actuator.

(Structure of the invention) In order to achieve the above object, this invention is structured as follows.

In other words, the suspension support of this invention is
An inner plate disposed on the inner circumferential side of the annular elastic body and an outer plate similarly disposed on the outer circumferential side of the annular elastic body and fixed to the body of the vehicle are each integrated with the annular elastic body, In addition, an actuator for controlling the damping force of the shock absorber is installed.

The end of the absorber rod is coupled to the inner plate so as not to rotate relative to the axis of the rod, and the actuator is integrally assembled to the inner plate.

(Description of Embodiments) This invention will be described below based on drawings showing embodiments. Note that the same components as in FIGS. 1 and 2 are given the same numbers and their explanations will be omitted. 3 and 4 show a first embodiment of this invention. In the figure, the suspension support 22 is an annular elastic body 22.
A, and a ring-shaped outer flange member 22b and an inner flange member 22c, which are fixed to the outer peripheral surface by baking or the like, form a ring body as a whole. That is, the suspension support 22 is disposed in the mounting hole 3 drilled in the vehicle body 1, and the outer edge of the outer flange member 22b, which is the outer plate of this support 22, is connected to the body 1 with the bolt 4 and nut 5. Fixed by Also suspension support 2
An actuator bracket 26 is placed on the upper surface of the inner flange member 22c, which is the inner plate of No. 2, and is welded to each other.

The inner flange member 22c and the bracket 26
As shown in FIG. 4, a D-shaped insertion hole 29 is formed at the joint portion with the main body. Correspondingly, the threaded portion 7a of the absorber rod 7 also has a D-shaped cross section. By inserting this threaded portion 7a into the insertion hole 29 and tightening the nut 8, the absorber rod 7 is inserted into the inner flange member 22.
c and the bracket 26. The bracket 26 is fixed to the inner peripheral surface of the annular elastic body 22a by baking or the like. The upper end of the bracket 26 is an outward flange 26b, to which the actuator 10 is connected by bolts 11 and nuts 12.

In the above configuration, when the absorber rod 7 rotates around its axis, this torque is transmitted to the annular elastic body 22a via the bracket 26 and the inner flange member 22c through the insertion hole 29 of the bracket 26, and further to the outer flange member. 22b to the vehicle body 1. At this time, the annular elastic body 22
Although a is twisted to some extent, the amount is small, so the rotation angle of the actuator 10 is also small, and the lead wire 13 does not wrap around the actuator 10. Fifth, a second embodiment of the present invention is shown in correspondence with FIG.

The suspension support 32 of this embodiment is
An outer flange portion 32b serving as an outer plate is fixed to the annular elastic body 32a with a portion thereof embedded inside the annular elastic body 32a. Further, an actuator bracket 26 having a flange 26b is fixed to the inner periphery of the center hole of the annular elastic body 32a by baking as in the first embodiment.

However, in this second embodiment, the actuator bracket 26 also serves as the inner plate of the suspension support 32, and a member corresponding to the inner flange member 22c of the first embodiment is not provided. Therefore, the threaded portion 7a of the absorber rod 7 is connected to the bracket 26 by a nut 8 as in the first embodiment.

Note that in FIG. 5, members that are considered to have the same or equivalent configuration as those in FIG. 3 are given the same reference numerals in the drawing, and redundant explanations will be omitted.

(Effects of the invention) In this way, the actuator is integrally assembled to the inner plate, which is integrated with the annular elastic body. Regardless, the rotation of the actuator is suppressed by the restraining force of the annular elastic body, thereby preventing excessive force from being applied to the lead wire of the actuator.
