  By the way, in recent years, by suppressing the displacement of the outer cylinder of the strut mount with respect to the fitting recess of the vehicle body panel, the relative displacement between the vehicle body panel and the strut is suppressed, and the steering stability and ride comfort of the vehicle are improved. Furthermore, there is an increasing demand for suppressing the generation of abnormal noise.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a strut mount that can suppress relative displacement between a vehicle body panel and a strut.

  In order to solve the above problems and achieve such an object, the strut mount of the present invention includes an outer cylinder whose outer peripheral surface is coated with a rubber film, an inner cylinder disposed inside the outer cylinder, A vehicle body panel in a strut rod provided between the outer cylinder and the inner cylinder and having a cylindrical elastic body that elastically connects the two and extending from the wheel side toward the vehicle body panel side. The inner cylinder is attached to the upper end portion on the side, and the outer cylinder is fitted into a fitting recess formed on the vehicle body panel and having an inner peripheral surface that gradually increases in diameter from the vehicle body panel side toward the wheel side. The outer peripheral surface of the outer cylinder gradually increases in diameter as it goes from the vehicle body panel side to the wheel side along its axial direction, and at least of both ends in the axial direction of the outer cylinder. One outer surface has a diameter Bulging portion that bulges toward the direction outwardly, characterized in that it is formed over the entire circumference.

In this invention, since the bulging portion that bulges outward in the radial direction is formed on the outer peripheral surface of at least one of the both end portions in the axial direction of the outer cylinder over the entire circumference, the rubber film is inserted into the fitting portion. Of the surface pressure generated between the rubber film and the inner peripheral surface of the fitting recess when the outer cylinder is pressed into the fitting recess by being pressed against the inner peripheral surface of the fitting recess, The surface pressure, that is, the frictional force generated between the bulging portion covering portion located on the protruding portion and the inner peripheral surface of the fitting recess is locally increased.
In addition, since the bulging portion is formed over the entire circumference, it is possible to suppress the frictional force from being varied for each portion along the circumferential direction.
As described above, the strut mount has a so-called twisting force that tilts its axis with respect to the axis of the fitting recess, a horizontal force perpendicular to the axis, or a rotational force around the axis, and further to this axis. Even if the vertical force along the line acts, it is possible to suppress the displacement of the strut mount with respect to the fitting recess.
In addition, since the bulging part is formed in the outer cylinder, it is also possible to increase the rigidity of the outer cylinder, and when the aforementioned force is applied to the strut mount, the outer cylinder is deformed to deform the strut mount. Can be prevented from being displaced with respect to the fitting recess.

Here, the said bulging part may be separately formed in the outer peripheral surface of the said both ends of an outer cylinder.
In this case, since the bulging portions are separately formed on the outer peripheral surfaces of the both end portions of the outer cylinder, the portion where the surface pressure and the frictional force are increased as described above is 2 along the axial direction of the outer cylinder. It can be reliably generated at a location. Therefore, when a force in the twisting direction is applied to the strut mount, it is possible to suppress the swing angle of the strut mount with respect to the fitting recess by receiving the force at the two bulging portions described above. It is possible to reliably suppress the strut mount from being displaced relative to the fitting recess.
In addition, since the bulging portions are formed separately on the outer peripheral surfaces of the both end portions of the outer cylinder in this way, the outer cylinder and the fitting recess are gradually enlarged in diameter from the vehicle body panel side toward the wheel side. When the strut mount is fitted into the fitting recess, the strut mount axis can be easily aligned with the axis of the fitting recess. Can be easily and accurately assembled to the body panel.

Even if the bulging portion is formed on the outer peripheral surface of one of the two end portions of the outer cylinder, for example, the inner peripheral surface shape of the fitting recess, the outer peripheral surface shape of the outer cylinder, and the bulging By appropriately selecting the dimensions and the like of the protruding portion, both the portion located on the other end portion of the outer cylinder in the rubber film and the bulging portion covering portion are brought into pressure contact with the inner peripheral surface of the fitting recess, and the above-mentioned The effect can be made effective.
For example, when the bulging portion is formed only at the upper end portion on the vehicle body panel side of the both ends of the outer cylinder, the inclination angle of the inner peripheral surface of the fitting recess with respect to the axis is greater than the inclination angle of the outer peripheral surface of the outer cylinder. In the case where the bulging portion is formed only at the lower end portion on the wheel side of the both ends of the outer cylinder, the inclination angle of the inner peripheral surface of the fitting recess with respect to the axis is greater than the inclination angle of the outer peripheral surface of the outer cylinder. May be increased.

In addition, the bulging portion may be formed in a semi-annular shape that opens inward in the radial direction in a longitudinal sectional view of the strut mount.
In this case, since the bulging portion is formed in the semi-annular shape, as described above, the surface pressure and frictional force generated between the bulging portion covering portion of the rubber film and the inner peripheral surface of the fitting concave portion. On the other hand, it is possible to prevent the rubber film and the inner peripheral surface of the fitting recess from being excessively heavily loaded and easily damaged.

Furthermore, in the rubber film, the thickness of the bulging portion covering portion located on the bulging portion may be thinner than the thickness of other portions.
In this case, in the rubber film, since the thickness of the bulging portion covering portion is thinner than the thickness of the other portion, it occurs between the bulging portion covering portion and the inner peripheral surface of the fitting recess. It is possible to reliably increase the surface pressure and the frictional force locally.

  According to this invention, the relative displacement between the vehicle body panel and the strut can be suppressed.

Further, when the bulging portions 15 and 16 are intermittently scattered or extended over the entire circumference of the outer cylinder 12, the numbers of the upper bulging portion 15 and the lower bulging portion 16 are set to each other. They may be the same or different.

Moreover, in the said embodiment, although the bracket 23 which supports the coil spring 25 from the upper end side was provided, a flange is protruded from the lower end edge of the outer cylinder 12 toward the radial direction outer side without providing this bracket 23. In addition, a coil spring having a diameter larger than that of the coil spring 25 shown in the embodiment may be used, and the large-diameter coil spring may be supported from the upper end side by the lower surface of the flange.
Also in this configuration, the strut mount is assembled without being fastened to the vehicle body panel 20 in a state where the first rubber film 11 is pressed against the inner peripheral surface of the fitting recess 21 as in the above embodiment.

Furthermore, instead of this configuration, the strut mount may be assembled to the vehicle body panel 20 by fastening the flange and the vehicle body panel 20 with a fastening member.
Moreover, in the said embodiment, although the bulging parts 15 and 16 were each formed in the both ends of the said axis O direction in the outer cylinder 12, the intermediate part of the said outer cylinder 12 of the said axis O direction was also shown. A bulging portion may be formed.

Furthermore, the longitudinal sectional view shape of the bulging portions 15 and 16 is not limited to the above-described embodiment. For example, the bulging portions 15 and 16 are appropriately formed, for example, in a rectangular ring shape or in a solid shape with the largest thickness in the outer cylinder 12. It may be changed.
Moreover, in the said embodiment, although the outer peripheral surface of the 1st rubber film 11 showed the structure extended linearly along the said inclination direction K by the said longitudinal cross sectional view, the outer peripheral surface of the bulging parts 15 and 16 was shown. By conforming to the shape, the thickness of the first rubber film 11 may be made equal over the entire region.

  Moreover, in the said embodiment, although the both-ends edge 12a, 12b in the said axis line O direction of the outer cylinder 12 was each formed in the radial direction inner side of this outer cylinder 12, the bulging parts 15 and 16 were formed, for example in FIG. As shown, the bulging portions 15 and 16 may be formed such that both end edges 12a and 12b in the axis O direction of the outer cylinder 12 are directed outward in the tilt direction K, respectively. Further, in the outer cylinder 12 shown in FIG. 3, a recess 18 that is recessed inward in the radial direction may be formed in the central portion in the direction of the axis O (FIG. 4A), or the recess 18 is formed. Instead, as shown in FIG. 4B, a convex portion 19 that protrudes outward in the radial direction may be formed in the central portion of the outer cylinder 12 in the axis O direction.
