  • the weight of (21) can be reduced. As a result, the amount of cargo that can be loaded on the trailer body (21) can be increased, and the loading capacity of the trailer (20) can be improved. In addition, by reducing the weight of the refrigerator (30) and trailer body (21), the manufacturing cost of the refrigerator (30) and trailer body (21) can be kept low.
  • the base plate (81) of the support member (80) is formed integrally with the bottom plate member (27) conventionally provided on the trailer body (21), and the bottom plate member (27 ) To support the refrigerator (30). That is, the bottom plate member (27) provided on the trailer body (21) has been conventionally used as a member for supporting the refrigerator (30). Therefore, according to this embodiment, the member installed in the trailer body (21) for mounting the refrigerator (30) can be reduced in size, and the weight of the trailer body (21) resulting from the installation of the support member (80) can be reduced. Skill can be gained by minimizing the increase.
  • the support member (80) is formed in a shape in which the front edge is arcuate (that is, a shape in which the left and right corners on the front end side are cut out).
  • the distance between 80) and the tractor (11) that pulls the trailer (20) is maintained. Therefore, according to the present embodiment, the front end surface of the trailer (20) and the tractor (11) can be brought close to each other without disturbing the travel of the trailer (20), and the trailer body (21) The size of the cargo room (24) can be secured to the maximum.
  • the engine (50), the generator (51), and the compressor (41), which are relatively heavy components of the refrigerator (30), are lower.
  • the evaporator (43) and the evaporator fan (45), which are relatively light, are attached to the upper structure (67), respectively, on the side structure (61).
  • the strength of the upper structure portion (67) of the frame body (60) can be lowered, and the refrigerator (30) can be reliably reduced in weight.
  • the guide piece is attached to the support member (80) of the trailer body (21).
  • the guide piece (85) may be provided.
  • the guide piece (85) is disposed along the right end of the support member (80) in the figure, and its tip protrudes above the top plate portion (83) of the support member (80).
  • the refrigerator (30) is positioned in the left-right direction by bringing the refrigerator (30) into contact with the guide piece (85). That is, the guide piece (85) constitutes guide means for guiding the refrigerator (30) to a predetermined position when the refrigerator (30) is attached.
  • the position of the refrigerator (30) in the vertical direction is naturally determined. Further, since the back surface of the refrigerator (30) is in contact with the front end surface of the loading platform (23), the position of the refrigerator (30) in the front-rear direction is also determined naturally. Therefore, if the guide member (85) is provided on the support member (80), the relative position between the refrigerator (30) and the trailer body (21) is uniquely determined, and the relative position to the trailer body (21) is determined. Installation work of the refrigerator (30) can be facilitated.
  • the force that provides the guide piece (85) to the support member (80) of the trailer body (21) may be provided to the refrigerator (30).
  • a clamp member (86) as shown in FIG. 11 may be used instead of the bolt! /, .
  • the clamp member (86) fixes the heat insulating wall (33) and the panel member (69) in a state where the sealing material (87) is sandwiched between both sides.
  • the present invention is useful for a trailer refrigerator and a trailer including the same.

Abstract

L'invention concerne un organe de support (80) sur une carrosserie de remorque (21). L'organe de support (80) fait saillie vers l'avant depuis une section d'extrémité inférieure d'une surface d'extrémité avant de la carrosserie de remorque (21). Une machine frigorifique (30) pour remorque est fixée sur la carrosserie de remorque (21), montée sur l'organe de support (80). Étant donné que la machine frigorifique (30) est supportée par en dessous par l'organe de support (80), la résistance nécessaire pour la structure de la machine frigorifique (30) est réduite, ceci réduisant le poids de la machine frigorifique (30).
