DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. In the figure, 5 is a vehicle body, and 6 is an underframe forming a bottom surface portion of the vehicle body 5. Reference numeral 2 is a side beam which is arranged on both sides in the width direction of the underframe 6 so as to be pulled through in the vehicle body longitudinal direction, and rails are integrally formed on the lower surface thereof. Usually, the side beam 2 is made of an extruded aluminum alloy profile. An aluminum honeycomb material 9 forming a floor portion is installed between the side beams 2. By forming the underframe 6 with the aluminum honeycomb material 9, the height of the underframe can be shortened while maintaining the conventional underframe rigidity, and the device installation space described later can be expanded.

Reference numeral 1 denotes a bodywork frame which supports a unitized underfloor equipment 4 arranged below the underframe 2. The body frame 1 is formed at both ends with engaging portions for engaging with the rails of the side beams 2 installed on both sides of the underframe 6, and has a length corresponding to the width dimension of the underframe 6 as a whole. , Has a substantially U-shaped configuration. A bolt hole for screwing a fastening bolt 8 for supporting and fixing the underfloor device 4 is formed in a horizontal portion of the body frame 1 which forms a device installation space with the lower surface of the underframe 6. ing. Further, a screw hole for screwing a screw 7 for supporting and fixing the equipment cover 3 installed on the side surface of the equipment chamber portion, that is, on the outer side of the vertical portion, is formed in the vertical portion of the body frame 1. There is. The body frame 1 configured as described above is installed on the rail of the side beam 2 so as to be movable in the longitudinal direction of the vehicle body. Further, a plurality of body frames 1 are installed in the longitudinal direction of the vehicle body, and a receiver of the underfloor equipment 4 is placed on each adjacent body frame 1 and is supported and fixed to the fastening bolt 8.

The equipment cover 3 has an engaging portion for engaging with a rail installed separately from a rail with which the body frame 1 formed on the side beam 2 is engaged. It is supported so that it can move in any direction. The final fixing to the side beam 2 of the device cover 3 is performed by the screw 7 as described above. The equipment cover 3 includes the body frames 1
It is installed so as to close the space.

In such a structure, the body frame 1 is inserted from a notch formed in a part of the rail of the side beam 2. The installation of the underfloor equipment 4 is performed as follows. First, after supporting the underfloor equipment 4 with a jack or the like and arranging the underfloor equipment 4 between the predetermined bodywork frames 1, the underfloor equipment 4 is lifted by a jack or the like so that the bodywork frame 1 sandwiches the underfloor equipment 4. It is shifted and positioned below the receiver of the underfloor equipment 4. Next, the underfloor equipment 4 is lowered and supported by the bodywork frame 1, and the underfloor equipment 4 is fixed to the bodywork frame 1 with fastening bolts 8. Further, although each body frame 1 is fixed to the side beam 2, a fixing tool is removably installed and fixed to the rail portion so that it can be easily removed during maintenance work.

According to this structure, since the side beam 2 holds the load of the underfloor equipment 4, it is possible to eliminate the load on the floor structure, that is, the aluminum honeycomb material 9. Therefore, the aluminum honeycomb material 9 does not need to have high strength in consideration of the weight of the underfloor equipment 4, and the weight can be reduced. Further, by using the bodywork frame 1 having the same function as that of the conventional vertical support member and the device beam integrated, the device support structure becomes simple and the underfloor device mounting work becomes easy. Furthermore, when a plurality of underfloor equipments 4 are supported by a plurality of bodywork frames 1 having the same specifications, the bottom surface of each underfloor equipment 4 can be smoothed without any special consideration.

Next, another embodiment of the present invention will be described with reference to FIG. The difference between this embodiment and the embodiment of FIG. 3 is that a side beam 2a made of steel is used instead of the side beam 2 that was an extruded aluminum alloy profile. A steel rail receiver 10 is attached to the side beam 2a by spot welding.

According to this structure, the body frame 1 can be used even when the entire vehicle body is made of steel, that is, structural steel or stainless steel, or a combination thereof. The same effect as the example can be achieved.

Next, another embodiment of the present invention will be described with reference to FIG. The difference between this embodiment and the embodiment of FIG. 3 is that the rail provided on the side beam 2b is cantilevered in cross section. That is, the rail of the side beam 2b is formed in a hook shape, and the engaging portion of the body frame 1 that engages with the rail is also formed in a hook shape, thereby simplifying both shapes and reducing the cost. It is intended.

Next, another embodiment of the present invention will be described with reference to FIG. In the figure, the side beam 2c has a rail formed on the lower surface thereof, and has a structure in which the underfloor equipment 4 is supported and fixed to the rail via mounting metal 11 and bolts 12. That is, the underfloor equipment 4 has a width dimension substantially the same as the underframe width dimension, and when installing such a large equipment, the underfloor equipment 4 is supported without using the bodywork frame. May be. The structure of this embodiment can be used in combination with the structure of the above-described embodiment, and it is possible to flexibly adapt to the size of the underfloor equipment 4 without significantly changing the specifications of the underframe. This is particularly effective when the specifications are changed after the vehicle is completed.

[0017]

According to the present invention, by supporting the underfloor equipment by using the bodywork frame, the structure of the underframe itself or various supporting members can be simplified, and the installation work of the underfloor equipment can be easily performed. You can
