[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil cooler for cooling hydraulic oil or lubricating oil used in a bulldozer or the like, and more particularly to an oil cooler mounting structure.

[0002]

2. Description of the Related Art Conventionally, an air-cooled oil cooler has been used for cooling hydraulic oil or lubricating oil for bulldozers. In order to mount such an oil cooler on a vehicle body, it must first be suspended and lowered by a crane or the like to the mounting position of the vehicle body because of its heavy weight. And at the time of installation, impact by the weight of oil cooler,
In order to avoid deformation of the vehicle body, it is necessary to attach to the float via flexible rubber or the like.

[0003]

However, as shown in FIG. 3, the radiator tag 2 is surrounded by a structural material.
In order to attach the oil cooler 22 to the
In order to suspend the radiator guard 21 from above using a crane using the suspending tool 23 provided on the ram 22, the structure 21a on the upper side of the radiator guard 21 must be removable. It becomes complicated. In order to avoid this, when the hinges 24 are used up and down as shown in FIG. 4, the oil cooler 22 is suspended from above by a crane, and the oil cooler 22 is rotatably mounted on the radiator guard 21 by the hinges 24. Thereafter, the crane can be removed and rotated for mounting. This mounting has the advantage that the oil cooler 22 is directly mounted on the vehicle body (in this case, a radiator guard) by the hinge 24, but is not a float mounting via rubber or the like, so that the impact after mounting and There was a drawback that body deformation could not be avoided.

[0004] In view of the above, the present invention provides an oil cooler mounting structure in which when mounting the oil cooler to a structure such as a radiator tag, the floats can be mounted sequentially and easily. It is intended to eliminate the drawbacks of the prior art.

[0005]

According to the present invention, a plate with a hole is provided at one side of an opening provided to accommodate an oil cooler in a structure. A plate with a pin engaging with a hole of the plate with a hole is fixed to the oil cooler having a bracket which is fixed and attached to upper and lower surfaces via rubber bushes, respectively. Screw holes for fixing the brackets on the oil cooler side by fastening means such as bolts are provided on the upper and lower inner surfaces of the opening.

[0007]

With the above construction, the oil cooler and the opening are first engaged with the pin holes, and then the upper and lower brackets of the oil cooler are attached to the upper and lower inner surfaces of the opening by fastening means such as bolts. be able to.

1 shows an embodiment of an oil cooler mounting structure according to the present invention, and FIG. 2 shows a detailed view of a main part of the present invention.

According to the present invention, a plate 4 with holes is fixed to one side of an opening 3 provided to accommodate the oil cooler 1 in a structure 2 such as a radiator tag. A plate 8 with a pin 9 for engaging with a hole 4a of the plate 4 with holes is fixed to the oil cooler 1 having brackets 6 and 7 attached to the lower surface via rubber bushes 5, respectively. ,
The upper and lower inner surfaces of the opening 3 of the structure 2 are provided with screw holes 12 and 13 for fixing the brackets 6 and 7 of the oil cooler 1 by fastening means 10 and 11 such as bolts, respectively. I have.

Plates 4 and 4 with holes are fixed horizontally above and below one side of the opening 3 so as to face inward while keeping a certain distance, and the plate 4 is provided with a hole 4a. ing.
Correspondingly, on one side of the oil cooler 1, plates 8, 8 projecting outward in the vertical direction are fixed at the same distance as the plates 4, 4. Pins 9, 9 which are engaged with the holes 4a in the vertical direction are fixed to the gate 8, respectively. The rubber bush 5 has rubber inside between the inner and outer cylindrical bodies, and the upper rubber bush 5 is horizontally fitted inside the upper part of the block 14.
Is fixed to the upper surface of the oil cooler 1. The bracket 6 includes a horizontal portion 6a and a bifurcated and vertically suspended vertical portion 6b. The vertical portion 6b is provided with a mounting hole for the coupling means 15. This causes block 14
Are mounted so that the vertical portion 6b of the bracket 6 is straddled. The rubber bush 5 is penetrated by the coupling means 15 between the two, and is tightened by the nut 16 to be integrated. The horizontal portion 6a of the bracket 6 is provided with a plurality of bolt holes 6c for mounting on the inner upper surface of the opening 3. The screw hole 12 is provided on the inner upper surface of the opening 3.

The lower rubber bush 5 is vertically fitted into the horizontal portion 7a of the bracket 7, and the horizontal portion 17a of the L-shaped plate 17 to which the vertical portion 17b is fixed below the oil cooler 1. It is attached in contact with the lower surface. The mounting hole for the connecting means 18 provided in the horizontal portion 17a and the rubber bush portion 5 are integrated with each other by penetrating the connecting means 18 and tightening with the nut 19. The vertical portion 7b of the bracket 7 has a plurality of bolt holes 7c for attaching to a plate 20 fixedly mounted upright on the inner and lower surfaces of the opening 3.
Is provided. The plate 20 is provided with the screw hole 13.

Next, a procedure for attaching the oil cooler 1 to the structure 2 will be described. First, the upper part of the oil cooler 1 is hung by a crane (not shown), and is suspended close to the opening 3 of the structure 2, and the pin 9 of the plate 8 of the oil cooler 1 is put on the plate of the opening 3. -Insert it into the hole 4a of the port 4. In this state, the crane is removed, and the oil cooler 1 is rotated about the pin 9 and pushed into the opening 3 to move to the mounting position. At this position, the horizontal part 6 of the bracket 6
When the bolt hole 6c of a is aligned with the screw hole 12 of the opening 3 and fastened by a fastening means 10 such as a bolt, the oil cooler
Is raised upward together with the bracket 6, and the oil cooler
The pin 9 of the roller 1 comes out of the hole 4 a of the opening 3. At the same time, it is fixed to the structure 2 via the rubber bush 5. Then, the bolt hole 7c of the vertical portion 7b of the lower bracket 7
When the oil cooler 1 is fixed to the structure 2 through the rubber bush 5 when the oil cooler 1 is tightened by the fastening means 11 in accordance with the screw hole 13 of the plate 20, the oil cooler 1 is mounted in a floating state.

Although the present invention does not specify the specific dimensions of the pin 9 coming out of the hole 4a when the bracket 6 is attached to the opening 3 in the embodiment, it should be considered at the design stage. Yes, the description is omitted in the present invention. Also, the inner and lower surfaces of the opening 3 and the oil
Although the case where the bracket 7 of the rack 1 is mounted via the plate 20 has been described, it is also possible to directly mount the bracket 7 on the inner and lower surfaces without the plate 20.

[0014]

As described above, according to the present invention, a plate with holes is fixed to one side of an opening provided to accommodate an oil cooler in a structure, and rubber bushes are provided on upper and lower surfaces, respectively. The oil cooler provided with the bracket attached through the hole is provided with a pin-fitting plate that engages with the hole of the holed plate.
