Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a radiator support structure that supports a radiator on an automobile body through elastic members disposed at the upper and lower parts of the radiator. It is.

(Prior art) Conventionally, as shown in Japanese Patent Application Laid-Open No. 57-84223,
By elastically supporting a radiator on the body of an automobile, the radiator is used as a dynamic damper for suppressing low frequency vibrations. By the way, in order to properly demonstrate the low frequency vibration suppression function of the radiator,
It is necessary to set the elastic modulus of the elastic member to a predetermined value by accurately assembling the elastic member that supports the upper end of the radiator in a predetermined state, taking into account manufacturing errors in the radiator and its mounting members, etc.
No consideration was given to this point in the prior art described above.

(Purpose of the invention) In view of the above points, the present invention provides an automobile radiator support structure in which an elastic member can be accurately and easily assembled in a state where the low-frequency vibration suppressing function can be fully exhibited. It is something.

(Structure of the invention) The present invention provides a radiator support structure in which a radiator is supported on a car body through elastic members provided at the upper and lower parts of the radiator. A bracket support wall disposed between the bracket and the upper part of the radiator and held by the bracket and a radiator support wall held at the upper end of the radiator are integrally coupled by an elastic body. At least one of the bracket support wall and the radiator support wall is provided with a positioning protrusion extending toward the other support wall. That is, by performing the work of assembling the elastic member and the work of attaching the radiator with reference to the protrusion, the elastic member can be accurately and easily assembled in a predetermined state.

(Example) In FIGS. 1 and 2, 1 is a radiator of an automobile, and elastic members 2, 2 made of elastic bodies such as rubber are disposed on the left and right sides of the lower end of the radiator.
It is attached to the lower cross member 4 of the vehicle body via brackets 3, 3, and is attached to the upper cross member 7 of the vehicle body via elastic members 5, 5 made of elastic bodies disposed on the left and right sides of the upper end and brackets 6, 6. By being attached to the radiator 1, the radiator 1 is elastically supported at the front position of the automobile.

As shown in FIGS. 3 and 4, the elastic member 5 includes a bracket support wall 50 held on the lower surface of the bracket 6, and a radiator support disposed below the bracket support wall 50 at a predetermined interval. The wall 51 is integrally connected with the front and rear side walls 52, 52, and the upper end of the radiator 1 is fitted between the pair of clamping walls 53, 53 connected to the side walls 52, 52. It is composed of When the radiator 1 is displaced upward, the radiator support wall 51 and the side walls 52, 52 are elastically deformed to absorb the impact, thereby suppressing low frequency vibrations of the vehicle body. Furthermore, a positioning projection 54 is provided on the lower surface of the bracket support wall 50 to protrude toward the radiator support wall 51.

The bracket 6 includes a vertical mounting plate 60 that is attached to the upper cross member 7 via bolts 70, a horizontal board 61 connected to the lower end of this mounting plate 60, and a tip end of this board 61. a regulating plate 62 protruding downward from the top, and ribs 63, 6 disposed between the mounting plate 60 and the substrate 61;
3, the mounting plate 60 is formed with elongated holes 64, 64 in the vertical direction, which serve as insertion holes for the bolts 70,
The mounting height of the bracket 6 can be adjusted by the elongated holes 64, 64.

In the above configuration, in order to install the radiator 1, the lower end of the radiator 1 is first supported by the lower cross member 4 of the vehicle body via the elastic member 2 and the bracket 3, and then the upper end of the radiator 1 is supported by the elastic member 5 and the bracket. 6 to the upper cross member 7 of the vehicle body. That is, the bracket 6 is installed on the upper end of the elastic member 5 with the upper end of the radiator 1 fitted between the clamping walls 53, 53 of the elastic member 5, and the mounting plate 60 of the bracket 6 is attached to the upper part with bolts 70. By fixing it to the cross member 7, the elastic member 5 is connected to the regulating plate 62 of the bracket 6 and the front lower end of the upper cross member 7.
Grasp the upper end of the

When assembling the elastic member 5, the protrusion 54 is used as a positioning gauge, and by appropriately setting the distance between the bracket support wall 50 and the radiator support wall 51 using the protrusion 54 as a reference, it is possible to reduce the amount of damage caused to the vehicle body. To effectively suppress frequency vibration. In other words, when the distance between the bracket support wall 50 and the radiator support wall 51 changes, the elastic modulus of the elastic member 5 in the vertical direction changes, and when the radiator 1 is used as a dynamic damper, the vibration suppressing function is exhibited. Since the area is determined by the weight of the radiator 1 and the elastic coefficient of the elastic member 5, the tip of the protrusion 54 is attached to the upper surface of the radiator support wall 51 so that the vibration suppressing function is exhibited in a preset low frequency area. The bracket 6 is fixed to the upper cross member 7 with the distance between the bracket support wall 50 and the radiator support wall 51 properly set by positioning the bracket 6 by a means such as bringing it into contact with the bracket support wall 50 and the radiator support wall 51.

In this way, when assembling the elastic member 5, positioning can be performed using the projections 54, thereby eliminating assembly errors and easily and accurately setting the distance between the bracket support wall 50 and the radiator support wall 51. be able to. Further, even if a manufacturing error occurs in the radiator 1 and its mounting members, the elastic member 5 can be assembled so as to always exhibit an appropriate vibration suppressing function in a predetermined low frequency range.

In the above embodiment, like the upper elastic member 5, the lower bracket 3 is made of an elastic body such as rubber, but the lower elastic member may be made of a compression spring. Furthermore, the elastic member 5 can be deformed into various shapes, such as forming an engaging protrusion on the upper end of the radiator 1 and forming a recess corresponding to the protrusion on the lower surface of the radiator support wall 51. I can do it. Instead of the positioning protrusion 54 protruding toward the bracket support wall 50, a protrusion may be provided on the upper surface of the radiator support wall 51, or a protrusion may be provided on both the bracket support wall 50 and the radiator support wall 51. Good too. Further, in the above embodiment, the projections 54 are formed over the entire length of the elastic member 5, but one or more projections 54 may be formed partially at both ends of the elastic member 5. good.

(Effects of the invention) As explained above, the present invention enables the elastic member to be accurately and easily assembled in a predetermined state using the protrusion as a reference so that the elastic modulus of the elastic member becomes a predetermined value. Even if a manufacturing error occurs in the mounting member, etc., the elastic coefficient of the elastic member can be appropriately set so that the radiator always exhibits its vibration suppressing function in a predetermined low frequency range. It is something.
