General-purpose frame structure for mounting powerplants

1. A general-purpose frame structure for mounting powerplants that is configured to mount a powerplant to a car body, the frame structure comprising:

four side frames having basal ends thereof to be attached to a fore end or a rear end of a cabin of the car body, the side frames being adapted to extend in a fore-and-aft direction of the car body on a substantially upper-left side, on a substantially lower-left side, on a substantially upper-right side, and on a substantially lower-right side of the powerplant;

a plurality of mounting devices to be interposed between the side frames and the powerplant to support the powerplant to the four side frames; and

a bracket for attaching, to an associated one of the side frames, a portion to be attached to the side frame in a link configured to couple the side frame with the cabin, a portion to be attached to the side frame in a link configured to couple the side frames to each other, or a portion to be attached to the side frame in a suspension to be installed to the side frame, wherein

the side frames have surfaces provided with a plurality of attachment openings arranged at specific intervals in a row in a length direction of the side frames, and side frame adjusters are configured to be interposed between the cabin and the side frames for adjusting relative positions of the cabin and the side frames,

the mounting devices are each configured to be fitted, at the side of an associated one of the side frames, into one or two or more attachment openings of the plurality of attachment openings, and mounting device adjusters are each configured to be interposed between a powerplant-side connection portion to be connected to the powerplant and a side frame-side connection portion to be connected to an associated one of the side frames, for adjusting relative positions of the connections portions, and

the bracket is configured to be fitted into one or two or more attachment openings of the plurality of attachment openings.

2. The general-purpose frame structure for mounting powerplants according to claim 1 , wherein the mounting device adjusters have spacers to be interposed between the powerplant-side connection portions and the side frame-side connection portions, in such a manner that the relative positions of the powerplant-side connection portions and the side frame-side connection portions are changeable according to the spacers.

3. The general-purpose frame structure for mounting powerplants according to claim 1 , wherein the side frame adjusters have spacers to be interposed between the cabin and the side frames, in such a manner that the relative positions of the cabin and the side frames are changeable according to the spacers.

4. The general-purpose frame structure for mounting powerplants according to claim 1 , wherein the side frame adjusters are configured to adjust the positions of the side frames in a width direction of the car body.

5. The general-purpose frame structure for mounting powerplants according to claim 1 , to wherein the side frame adjusters have shafts adapted to extend in a direction substantially perpendicular to the fore-and-aft direction of the car body, in such a manner that the side frames are angularly adjustable about the shafts.

6. The general-purpose frame structure for mounting powerplants according to claim 1 , further comprising coupling members for coupling leading ends of the plurality of side frames to each other.
