  In the above structure, the width of the radiator is limited to a width shorter than the inner distance (frame width) between the left and right side frames, and cannot be expanded beyond the frame width.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a radiator support structure for a vehicle in which the width of the radiator can be wider than the frame width.

  In order to achieve the above object, a radiator support structure for a vehicle according to the present invention includes a pair of left and right side frames, a radiator, and a pair of left and right brackets.

  The left and right side frames integrally have an upper plate portion, a side plate portion, and a lower plate portion, and are separated in the vehicle width direction and extend in the front-rear direction. The side plate portion is bent and extended downward from the outer edge in the vehicle width direction of the upper plate portion, and the lower plate portion is bent and extended inward in the vehicle width direction from the lower end edge of the side plate portion. The radiator is disposed between the front end portions of the left and right side frames.

  The left and right brackets each have a cab support portion and a radiator support portion, and are respectively fixed to the left and right side frames. The cab support portion is fixed to the outer surface of the side plate portion of the side frame and extends upward, and supports the cab from below. The radiator support portion is integrally formed with the cab support portion, protrudes inward in the vehicle width direction, and supports the radiator from the side.

  Upper and lower notches for narrowing the plate width of the upper plate portion and the lower plate portion are formed on the inner side in the vehicle width direction of the upper plate portion and the lower plate portion of the front end portions of the left and right side frames, respectively.

  In the above configuration, the left and right side frames have a general area where no notch is formed behind the front end and a front end where the notch is formed, and the frame width of the left and right side frames is the general area. Defined by the inner distance between frames. Therefore, set the width of the radiator so that both ends of the radiator in the vehicle width direction enter the upper and lower cutouts of the left and right side frames, and the vehicle width of the radiator with both ends of the radiator entered into the cutout By supporting both sides in the direction with the left and right brackets, the width of the radiator can be made wider than the frame width.

  Moreover, since the bracket is not fixed to the upper plate portion of the side frame, it is not necessary to secure a width for fixing the bracket to the upper plate portion, and the upper plate portion and the lower plate portion of the side frame are widened to widen the radiator. The plate width can be reduced.

  According to the radiator support structure for a vehicle of the present invention, the width of the radiator can be made wider than the frame width.

It is a top view of the radiator support structure of the vehicle shown in FIG. FIG. 3 is a cross-sectional view taken along the line III-III of the radiator support structure of the vehicle shown in FIG. 2.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 1 to 3, a vehicle 2 that employs the radiator support structure 1 of the present embodiment includes a pair of left and right side frames 3, a cross frame 4, a pair of left and right brackets 5, and a radiator 6. Is provided. Since the side frame 3 and the bracket 5 have the same configuration on the left and right, only one (the left side facing the front of the vehicle) is shown in the drawing, and the other (the right side) is not shown.

  The pair of left and right side frames 3 and the cross frame 4 constitute a body frame, and the left and right side frames 3 are separated from each other in the vehicle width direction and extend in the front-rear direction. Each side frame 3 has a U-shaped cross section that opens inward in the vehicle width direction, and integrally includes an upper plate portion 7, a side plate portion 8, and a lower plate portion 9. The side plate part 8 stands up and down. The upper plate portion 7 extends from the upper edge of the side plate portion 8 by bending inward in the vehicle width direction. The lower plate portion 9 extends from the lower end edge of the side plate portion 8 while being bent inward in the vehicle width direction, and faces the upper plate portion 7.

  A notch 7a for narrowing the plate width of the upper plate portion 7 is formed on the inner side in the vehicle width direction of the upper plate portion 7 of the front end portion 31 of the side frame 3, and the vehicle of the lower plate portion 9 of the front end portion 31 of the side frame 3 is formed. A notch 9a for narrowing the plate width of the lower plate portion 9 is formed on the inner side in the width direction. Inside the U-shaped cross section of the front end portion 31 of the side frame 3, has a U-shaped cross section that bends along the U shape of the side frame 3, and comes into surface contact with the inside of the U-shaped cross section of the side frame 3. A reinforcing member 33 (see FIG. 3) for reinforcing 31 is fixed. The reinforcing member 33 compensates for a decrease in rigidity of the front end portion 31 of the side frame 3 due to the notches 7a and 9a. The edge of the reinforcing member 33 on the inner side in the vehicle width direction does not protrude further inward in the vehicle width direction than the front end portion 31 (notches 7a, 9a) of the side frame 3.

  The cross frame 4 extends in the vehicle width direction at the front portion of the vehicle 2, and both ends thereof are fastened to the front end portions 31 of the left and right side frames 3 by bolts (not shown), respectively. The front end 31 is connected.

  The left and right brackets 5 are respectively fixed to the front end portions 31 of the left and right side frames 3. Each bracket 5 is integrally formed with a cab support portion (cab mount portion) 10 and a radiator support portion (radiator mount portion) 11 by casting.

  The cab support portion 10 is fixed to the outer surface of the side plate portion 8 of the side frame 3 with a plurality of bolts 12 and extends upward, and supports the front end portion 13a of the cab 13 so as to be rotatable (being tiltable) from below. The radiator support portion 11 protrudes inward in the vehicle width direction from the cab support portion 10, and the radiator side bracket 14 fixed to the side of the radiator 6 is fastened to the radiator support portion 11 from above and below by bolts 15. Thereby, the cab support part 10 supports the radiator 6 from the side.

  The left and right side frames 3 include a general region 32 where the notches 7a and 9a are not formed behind the front end portion 31 and a front end portion 31 where the notches 7a and 9a are formed. The frame width is defined by the inner distance between the frames in the general region 32. The width of the radiator 6 in the vehicle width direction is set such that both ends thereof enter the upper and lower cutouts 7a and 9a of the left and right side frames 3, and both ends of the radiator 6 enter the cutouts 7a and 9a. In the invaded state, both sides of the radiator 6 in the vehicle width direction are supported by the left and right brackets 5. Therefore, the width of the radiator 6 can be made larger than the frame width (the inner distance between frames of the general region 32). In the present embodiment, in the general region 32, the plate width of the upper plate portion 7 and the plate width of the lower plate portion 9 are substantially equal, but the upper notch 7a is formed deeper than the lower notch 9a, At the front end portion 31, the plate width of the upper plate portion 7 is narrower than the plate width of the lower plate portion 9.

  Further, since the bracket 5 is not fixed to the upper plate portion 7 of the side frame 3, it is not necessary to secure a width for fixing the bracket 5 to the upper plate portion 7, and the upper portion of the side frame 3 is increased for widening the radiator 6. The plate width of the plate portion 7 and the lower plate portion 9 can be reduced.

  In the above embodiment, the radiator support portion 11 of the bracket 5 does not need to be spaced upward from the upper plate portion 7 of the side frame 3, and the radiator support portion 11 may be in contact with the upper plate portion 7. .
