Abstract

<P>PROBLEM TO BE SOLVED: To provide an auxiliary machine support structure wherein light weight and rationalization of an installation process are accomplished. <P>SOLUTION: A hollow-like side rail 11 extending in a longitudinal direction of a vehicle is formed by extrusion of aluminum alloy and a cross member 12, i.e., an aluminum alloy pipe is penetrated through the side rail 11 in a vehicle width direction to be welded to each other. A bracket 15 provided on an end surface of a tank 14 is fastened to a base 13 fixed to the cross member 12. Namely, light weight and rationalization of the installation process is accomplished while ensuring rigidity also utilizing the cross member 12, i.e., a constitution element of a chassis frame for support of the tank 14. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to an auxiliary machine support structure suitable for a vehicle.

  FIG. 2 shows an example of a conventional auxiliary machine support structure, which includes an L-shaped support 2 in contact with the bottom surface and the back surface of the tank 1 and a band 3 in contact with the top surface and the front surface of the tank 1.

  The support 2 has a vertical portion 5 in contact with the rear surface of the tank 1 fixed to a side rail 6 as a component of the chassis frame so that a horizontal portion 4 in contact with the bottom surface of the tank 1 faces the vehicle outer side.

  In the band 3, the protrusion 7 provided at one end engages with the hole 8 at the upper end of the vertical portion 5, and the bolt 9 provided at the other end is inserted into the hole 10 at the tip of the horizontal portion 4. The tank 1 is mounted on the chassis frame by tightening a combined nut (not shown).

Further, it has been proposed to reduce the weight of the vehicle body by using an aluminum alloy as a material for the chassis frame (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 10-314869

  However, Patent Document 1 does not provide a structure for attaching an auxiliary machine such as a tank 1 to a chassis frame. Even if an aluminum alloy is used for the auxiliary support structure shown in FIG. 2, the assembly process can be streamlined. Is not achieved.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide an auxiliary machine support structure that can achieve weight reduction and rationalization of an assembly process.

  In order to achieve the above object, according to the present invention, a side rail and a cross member penetrating the side rail in the vehicle width direction are formed of an aluminum alloy, and an accessory is attached to an end of the cross member.

  Moreover, it has the structure which has a some cross member and constructed | assembled the auxiliary machine in the edge part of an adjacent cross member.

  In the present invention, the side rail auxiliary machine, which is a component of the chassis frame, is also used for mounting, and the parts required for mounting the auxiliary machine are reduced.

  (1) In the first aspect of the present invention, the side rail and the cross member are formed of an aluminum alloy, and the auxiliary machine is attached to the cross member that is a component of the chassis frame. This simplifies the assembly process, thereby improving productivity and reducing costs.

  (2) In the invention described in claim 2, since the auxiliary machine is installed on the adjacent cross member, the auxiliary machine can be supported in a stable state.

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

  FIG. 1 shows an example of an embodiment of an auxiliary machine support structure according to the present invention. A side rail 11 having a rectangular closed cross section and extending in the vehicle front-rear direction is formed by extrusion of an aluminum alloy. A plurality of cross members 12 that are pipes are passed through the side rails 11 in the vehicle width direction, and the cross members 12 and the side rails 11 are welded.

  The pedestal 13 is fixed to the cross member 12 so as to face upward, and brackets 15 are provided on the vehicle front and rear end surfaces of the tank 14 to be mounted on the chassis frame, and the bracket 15 is placed on the pedestal 13. These are bolted to each other.

  In other words, the hollow side rail 11 and the cross member 12 are formed of an aluminum alloy, and the cross member 12 that is a component of the chassis frame is also used to support the tank 14. Lightening of structure and rationalization of assembly process can be achieved.

  Further, since the tank 14 is installed on the adjacent cross member 12, the tank 14 can be supported in a stable state.

  It should be noted that the auxiliary machine support structure of the present invention is not limited to the above-described embodiment, and it is needless to say that changes can be made without departing from the gist of the present invention.

  The auxiliary machine support structure of the present invention can be applied to various vehicle types.

It is a perspective view which shows an example of embodiment of the auxiliary machine support structure of this invention. It is a perspective view which shows an example of the conventional auxiliary machine support structure.
