DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a structure that supports parts that are placed in the engine room of a vehicle and are subjected to vibration loads in the vertical direction of the vehicle due to vibrations when the vehicle is running. be.

(Prior Art) Generally, a radiator upper support extending in the width direction of the vehicle is disposed at the front of a vehicle, and components in the engine compartment such as a radiator and a battery are disposed behind the radiator support. In order to suppress vibrations of the parts in the engine room in the vertical direction, the parts in the engine room are mounted with upper and lower parts supported.

For example, Japanese Utility Model Application Publication No. 60-46335 discloses a structure for supporting the upper side of a radiator. This structure will be explained below based on FIGS. 7 and 8.

A radiator 11 is disposed in the engine room so as to stand up in the vehicle width direction and the vehicle vertical direction. A radiator upper support 22 extending in the vehicle width direction is disposed on the front side of the radiator 11 in the longitudinal direction of the vehicle, and the radiator upper support 22 is formed in a substantially U-shaped cross section with an open bottom. A plate-shaped bracket 33 extending in the longitudinal direction of the vehicle is fastened to the upper surface of the radiator upper support 22 with bolts and nuts. A through hole 33a is formed at the rear of the bracket 33, and an elastic member 33b is fitted into the through hole 33a. A support 33C is fitted to the elastic member 33b from below, and the upper part of the radiator 11 is supported on the lower surface of the support 33c.

(Problem B to be Solved by the Invention) In the conventional technology, the rear part of the bracket extending in the longitudinal direction of the vehicle supports the upper part of the radiator. The front portion of this bracket is coupled to the upper surface of a radiator upper support extending in the vehicle width direction, which is offset toward the front of the vehicle with respect to the radiator. Therefore, the rear part of the bracket is displaced in the vertical direction of the vehicle with respect to the front part of the bracket due to the vertical vibration of the radiator caused by the vertical vibration of the vehicle when the vehicle is running. This displacement of the rear part of the bracket applies a torsional load to the radiator upper support coupled to the front part of the bracket. In order to prevent deformation under this load, the radiator upper support is required to have high torsional rigidity.

Therefore, an object of the present invention is to reduce the load in the torsional direction applied to the radiator upper support by dispersing and supporting the load applied to the bracket, and to suppress the torsional rigidity required for the radiator upper support.

(Example) Next, an example of the present invention will be described based on FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, and FIG. 6.

A radiator upper support 2 extending in the vehicle width direction is disposed on the front side in the vehicle longitudinal direction of the radiator 1 extending in the vehicle width direction and the vehicle vertical direction, and the radiator number support 2 is formed in a hat-shaped cross section with an open bottom. There is. A front side member 4 extending in the longitudinal direction of the vehicle is disposed at a position lower than the radiator upper support 2.

The radiator side support 5 is formed in a hunt-shaped cross section that extends in the vehicle vertical direction and is open at the rear in the vehicle longitudinal direction, and this radiator side support 5 connects the front side member 4 and the radiator upper support 2. A flange 5a extending forward is formed at the upper end of the front wall of the radiator side support 5, and this flange 5a is connected to the front flange 2 of the radiator upper support 2.
It is connected to a. A flange 5b extending in the vehicle width direction is formed at the rear upper end of the radiator side support 5, and this flange 5b is connected to the radiator upper support 2.
It is connected to the rear wall 2B of.

Further, the lower part of the outer wall of the radiator side support 5 is coupled to the outer surface of the front side member 4, and the flange 5C extending inward in the vehicle width direction formed at the lower end of the inner wall of the radiator side support 5 and the front wall of the radiator side support 5 are connected to the outer surface of the front side member 4. A flange 5d formed at the lower end and extending toward the front of the vehicle is coupled to the upper surface of the front side member 4.

On the other hand, a bracket 3A extending in the longitudinal direction of the vehicle is connected to the radiator side support 5, and this platen 1
-3A is formed with a pair of side walls 3a, 3a extending in the vehicle vertical direction and longitudinal direction, and an upper wall 3b is formed by connecting the upper ends of these pair of side walls 3a, 3a. Front portions of the pair of side walls 3a, 3a are coupled to opposing surfaces of the outer and inner walls of the radiator side support 5. Further, the front portion of the upper wall 3b of the bracket 3A is coupled to a flange 2b formed on the radiator upper support 2 and extending toward the rear of the vehicle.

A bracket 3B extending in the vehicle width direction is coupled to the rear part of the upper wall 3b of the bracket 3A.
supports the upper part of the outer end of the radiator l in the vehicle width direction.

As yet another embodiment, the shape of the platen 3A as shown in FIGS. 5 and 6 can be considered.

The bracket 3A in FIG. 5 is bifurcated from the rear to the front and extends in the longitudinal direction of the vehicle. This bracket 3
The front portion of A is connected to opposing surfaces of the outer and inner walls of the radiator side support 5 at two locations in the longitudinal direction of the vehicle so as to suppress displacement of the rear portion of the bracket 3A in the vehicle vertical direction. On the other hand, the bracket 7) 3A in Fig. 6 is formed with a flange 3C extending downward from the front of the horizontal part extending in the longitudinal direction of the vehicle, and this flange 3C suppresses displacement of the rear part of the bracket 3A in the vertical direction of the vehicle.

The vibration of the radiator l in the vehicle vertical direction is caused by platen) 3B,
It is transmitted to the radiator side support 5 extending in the vertical direction of the vehicle via the platen) 3A, and is distributed to the radiator upper support 2 and the front side member 4. Therefore, the load applied to the radiator upper support 2 in the torsional direction is reduced, and the torsional rigidity required of the radiator upper support 2 is kept low.

Furthermore, vibrations of the radiator I in the vehicle vertical direction are transmitted as a vertical load to the rear part of the bracket 3A via the bracket 3B. Here, the side walls 3a, 3a of the bracket 3A are coupled along a vertical wall formed on the radiator side support 5 and extending in the vertical direction. Since the rotation of the side walls 3a, 3a of the bracket 3A in the longitudinal and vertical directions of the vehicle is restricted, and the movement of the entire bracket 3A is restricted, displacement of the rear part of the bracket 3A with respect to the front part of the platen 3A is suppressed. Therefore, radiator side support 5
The torsional load applied to the radiator in the longitudinal direction is suppressed, and the load applied to the radiator upper support 2 coupled to the radiator side support 5 in the torsional direction is reduced. As a result, the torsional rigidity required of the radiator upper support 2 is low (suppressed).

Furthermore, by eliminating the bracket on the top surface of the radiator upper support 2, the radiator upper support 2
The appearance of the top surface is improved, and the space above the radiator upper support 2 is increased. This space can be used to expand the cross section of the hood's inner panel, making it easier to supplement the hood.

Strength becomes possible.

(Effects of the Invention) According to the present invention, vibrations of parts in the engine room in the vehicle vertical direction are dispersed to the radiator upper support and the vehicle frame members via the radiator side support extending in the vehicle vertical direction. The load to be borne is reduced.

Therefore, the load in the torsion direction applied to the radiator upper support is reduced, and the torsional rigidity required of the radiator upper support is kept low.
