Therefore, according to the present invention, it is possible to provide a vehicle for land transportation that can cope with a lower floor while the minimum ground height is 250 mm or more.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.
<First Embodiment>
FIG. 1 is a partial rear view showing a mounting structure of a condensing unit 1 according to the first embodiment, and FIG. 2 is a partial perspective view. The first embodiment is applied to a vehicle for land transportation having a refrigeration apparatus. The basic configuration is as described with reference to FIGS. 14 to 16, and the first embodiment will be described below. A characteristic part of the form will be described. Further, the same components as those in FIGS. 14 to 16 are denoted by the same reference numerals as those in FIGS.
As shown in FIGS. 1 and 2, the first embodiment uses a bracket 60 made of steel having a L-shaped cross section to attach the condensing unit 1 to a horizontal 53 having a U-shaped cross section. The bracket 60 includes a horizontal fixing portion 61 that is fixed to the horizontal 53 and a unit fixing portion 62 that is fixed to the condensing unit 1. The horizontal fixing portion 61 and the unit fixing portion 62 are integrally formed at a right angle. Each of the horizontal fixing portion 61 and the unit fixing portion 62 has a through-hole through which the bolt B passes at the center.

  The bracket 60 is fixed by the bolt B in a state where the flat surface (fixed surface) of the horizontal fixing portion 61 faces and contacts the lower surface of the horizontal 53. The bracket 60 is fixed by the bolt B in a state where the surface (fixed surface) of the unit fixing portion 62 faces and contacts the side surface of the condensing unit 1. Therefore, the gap between the horizontal 53 and the condensing unit 1 can be made narrower than when the condensing unit 1 is attached to the horizontal 53 using the conventional Z-shaped bracket 54 shown in FIG. it can. That is, conventionally, the Z-shaped bracket 54 is suspended on the side 53, and the condensing unit 1 is suspended on the bracket 54, which corresponds to the vertical portion of the bracket 54 in the figure. A gap is inevitably generated between the horizontal 53 and the condensing unit 1. On the other hand, in the first embodiment, since the unit fixing portion 62 arranged in the vertical direction in the drawing is arranged to face the side surface of the condensing unit 1, the horizontal 53 and the condensing unit 1 The gap between them can be reduced. In particular, in the first embodiment, the condensing unit 1 is attached to the horizontal 53 by the bracket 60 so that the upper surface of the condensing unit 1 and the fixing surface of the horizontal fixing portion 61 coincide with each other. The gap between the horizontal 53 and the condensing unit 1 can be eliminated. Therefore, according to the first embodiment, it is possible to cope with a lower floor of the vehicle. 1 and 2 show only one end of the horizontal 53, the condensing unit 1 is fixed to the other end of the horizontal 53 by the bracket 60 in the same manner as in FIGS. Yes.

  Further, in the first embodiment, the unit fixing portion 62 of the bracket 60 is attached by the bolt B in a state of facing the side surface of the condensing unit 1. Therefore, the stress generated in the unit fixing portion 62 by attaching the condensing unit 1 is a shear stress. On the other hand, in the conventional Z-shaped bracket 54, the portion to which the condensing unit 1 is attached is tensile stress or compressive stress. Generally, the same material has higher strength against shear stress than tensile stress or compressive stress. Therefore, according to 1st Embodiment, the effect that the intensity | strength of the attachment part of the condensing unit 1 improves can also be enjoyed.

  In addition, according to the first embodiment, it is possible to enjoy the effect of preventing moisture from entering the condensing unit 1 due to rainwater or the like. In other words, in the first embodiment, the upper surface of the condensing unit 1 and the fixed surface of the fixed portion 61 that lies side by side coincide with each other. Therefore, the fixed portion 61 of the bracket 60 that is laid sideways becomes “eave” against the moisture to be infiltrated, and there is no gap between the laid 53 and the condensing unit 1. Thus, it is possible to prevent moisture from entering.

1 and 2 show the mounting structure for one laying 53. FIG. As described above, a plurality of laterally extending 53 is disposed at a predetermined interval in the front-rear direction of the vehicle. The mounting structure according to the embodiment can be applied.
Moreover, in 1st Embodiment, although the bracket 60 extended in the longitudinal direction (vehicle front-back direction) of the condensing unit 1 was used, this invention is not limited to this. The bracket 60 having a short length according to the present embodiment can be intermittently disposed at a position corresponding to the horizontal 53.

Moreover, the casing which comprises the side surface of the condensing unit 1 bears the part corresponded to the unit fixing | fixed part 62 by 1st Embodiment.

Also in the second embodiment, as in the first embodiment, the gap between the horizontal 53 and the condensing unit 1 can be narrowed. In particular, the gap between the horizontal 53 and the condensing unit 1 can be reduced. Can be eliminated.
Moreover, since the casing which comprises the side surface of the condensing unit 1 bears the part equivalent to the unit fixing | fixed part 62 by 1st Embodiment, the operation | work which attaches the bracket 60 with respect to the condensing unit 1 becomes unnecessary. .
Furthermore, since it is not necessary to separately provide a portion corresponding to the unit fixing portion 62 according to the first embodiment, it contributes to weight reduction including the condensing unit 1. On the other hand, assuming that the same weight as that of the first embodiment is allowed, more attachment points can be provided for the plurality of transverse 53, thereby eliminating stress concentration on a specific attachment part. can do.
