[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator support structure for a vehicle such as an automobile.

[0002]

2. Description of the Related Art As is well known, a radiator for an automobile is basically mounted on a back surface of a radiator core support panel via a bracket. In order to stabilize the mounting of the radiator, a lower surface of the radiator is mounted on a radiator core lower. It is supported by the radiator lower bracket attached to the member.

[0003] Referring to Fig. 3, reference numeral 1 denotes a radiator core disposed below a radiator core support panel (both not shown) provided between front hood ledge panels at front ends of engine rooms E and R. A lower member,
A front panel 2 having a substantially U-shaped cross section and a rear panel 3 joined to the rear side are formed into a closed cross section, and a radiator lower bracket 4 having a support seat 5 recessed is joined to the rear panel 3.

A radiator 7 has a mounting pin 8 as a lower mounting portion projecting from the center of both sides of the lower surface thereof.
An elastic body 9 such as rubber is fitted to the mounting pin 8 and fitted to the support seat 5, whereby the lower surface of the radiator 7 is supported by the radiator lower bracket 4 to stabilize the mounting of the radiator 7. I'm trying. The support seat 4 has a relief hole 6 for the mounting pin 8 when the radiator 7 vibrates in the vertical direction. This similar structure is described, for example, in Japanese Utility Model Laid-Open No. 60-1560.
No. 27 gazette.

[0005]

As described above, the radiator lower bracket 4 is joined to the back surface of the rear panel 3 of the radiator core lower member 1 and extends rearward and extends. Since the lower surface of the radiator 7 is supported via the mounting pins 8 and the elastic members 9 and cantileverly supported on the so-called rear panel 3, the radiator 7
It is unavoidable that the radiator lower bracket 4 needs to be increased in thickness or a separate reinforcing structure needs to be adopted as a countermeasure against the above disadvantage. I will.

Accordingly, the present invention provides a radiator lower bracket having an increased plate thickness or a large size, or a special reinforcing member provided.
It is an object of the present invention to provide a radiator support structure capable of increasing the support rigidity without accompanying the like.

[0007]

A radiator lower bracket extends rearward from a radiator core lower member disposed below a radiator core support panel laid between hood ledge panels on both sides at a front end of an engine room. A lower mounting portion of the radiator is mounted on the radiator lower bracket via an elastic body, and an under member extending rearward from the radiator core lower member and extending between the radiator core lower member and the vehicle body side member. The radiator lower bracket is disposed so as to pass through a lower corresponding position, and further, a cushioning member is arranged to avoid direct interference with an under member of the lower mounting portion when the elastic body is in a contracted state by a predetermined amount. is there.

[0008]

When the radiator is moved downward by the vertical vibration and the elastic body contracts by a predetermined amount, the lower mounting portion of the radiator is received by the under member, and the under member bears the load. At this time, the lower mounting portion abuts on the cushioning member to avoid direct interference with the under member, thereby preventing generation of abnormal noise such as a tapping sound.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings, in which the same reference numerals are given to the same parts as in the above-mentioned conventional construction.

In FIGS. 1 and 2, reference numeral 1 denotes a radiator core lower member formed in a closed cross section by a front panel 2 having a substantially U-shaped cross section and a rear panel 3 joined to the rear side thereof. It is arranged below the radiator core support panel laid between the hood ledge panels on both sides of the radiator core.

Reference numeral 10 denotes a radiator lower bracket that is joined to the rear surface of the rear panel 3 of the radiator core lower member 1 and extends rearward to support the lower surface of the radiator 7. The radiator lower bracket 10 has a support seat 11. At the center of the support seat 11, a relief hole 12 for a mounting pin 8 as a lower mounting portion projecting from the center of both sides of the lower surface of the radiator 7 is formed. Further, the base portion 13 of the radiator lower bracket 10 is extended and joined to a substantially lower half of the rear panel 3 up to the joint flange 1a with the front panel 2 to reinforce the rear panel.

The radiator 7 has an elastic body 9 made of rubber or the like fitted on the mounting pin 8, and accommodates the elastic body 9 in the support seat 11, and is supported by the radiator lower bracket 10.

Reference numeral 14 denotes an engine mount member serving as an under member which extends across the lower surface of the radiator core lower member 1 and the lower surface of the engine E. The engine mount member 14 has a front end portion of the radiator lower bracket 10.
Is disposed adjacent to the radiator lower bracket 10 in a position corresponding to the lower side of the radiator lower bracket 10, and a rubber or the like is provided at a position corresponding to the support seat 10 on the upper surface of the front end of the engine mount member 1. The cushioning member 15 is attached so as to avoid direct interference of the mounting pin 8 with the engine mount member 14 when the elastic body 9 is contracted (compressed) by a predetermined amount. Also, the under member does not necessarily need to be an engine mount member for supporting the engine, but extends rearward from the radiator lower member 1.
It may be a case where it is joined to a cross member, a side member lower surface, a dash lower panel, or the like, not shown.

In this embodiment, as shown in FIG. 2, since the radiator 7 is disposed over substantially half of the front end portion of the engine room E / R in the vehicle width direction, the engine mount member 14 is substantially aligned with the vehicle body center line. The radiator 7 passes through a position corresponding to the lower side of the radiator lower bracket 10 on the vehicle body center side of the radiator 7, and the radiator 7 has the engine room ER as shown by a chain line in FIG. If the engine mount member 14 is a large-sized one which is disposed over substantially the entire width at the front end, the engine mount member 14 is formed in a substantially Y-shape with a front side divided into two forks as shown by a chain line in FIG. The portion may be disposed so as to pass through the lower corresponding positions of the radiator lower brackets 10 on both sides of the radiator 7. In any of the above cases, the jack-up point 16 is formed by bulging the lower part of the radiator lower bracket on the lower surface of the engine mount member 14.

The rear end of the engine mount member 14 is firmly fixed to the dash lower cross member 17, and the rear load is applied through the dash lower cross member 17 to the front side member extension 18, the suspension mount member 19, and the front side member. 20 and the like.

According to the structure of the embodiment described above, when the radiator 7 vibrates in the vertical direction due to the vibration during running of the vehicle or the like,
The elastic body 9 elastically deforms in the support seat 11 of the radiator lower bracket 10 to perform a vibration damping action. Here, when the elastic body 9 contracts (compresses) by a predetermined amount due to the downward movement of the radiator 7 during this vibration, the mounting pin 8 passes through the clearance hole 12 and is received by the engine mount member 14, and the load is applied by the engine mount member 14. Will be borne. As a result, even if the radiator lower bracket 10 has a cantilevered support structure on the radiator core lower member 1, no excessive input acts on its joint, and the radiator 7 as a whole does not act.
Support rigidity can be increased. Also, at this time, the mounting pin 8 comes into contact with the cushioning member 15 and direct interference with the engine mount member 14 is avoided, so that it is possible to avoid generation of unpleasant hitting sound, metal impact sound, and the like.

Further, as described above, if the jack-up point 16 of the engine mount member 14 is set at the lower side of the radiator lower bracket 10, the radiator lower bracket 10 is mounted on the rear panel 3 of the radiator core lower member 1. Since it functions as a force, it can sufficiently oppose jack-up input.

[0018]

As described above, according to the present invention, when the radiator vibrates up and down and the elastic body contracts by a predetermined amount, the lower mounting portion of the radiator is received by the under member, and the under member can bear the load. As a result, the input load on the radiator lower bracket can be reduced, and as a result, the radiator lower bracket can be increased in size and thickness, and the stiffness of the radiator can be increased without the need for a dedicated reinforcing material. , Reliability can be further improved.
