Description

[Detailed Description of the Invention] The present invention relates to a radiator bracket for an agricultural tractor, and its purpose is to increase the mounting strength of the bracket.

Since the radiator bracket is vertically long and has a small width in the longitudinal direction of the vehicle body, there is a problem in that it is difficult to increase the mounting strength when mounting it on the vehicle body frame.

In order to solve the above problem, the present invention uses a battery bracket to increase the mounting strength of the radiator bracket.It is explained as follows using a drawing. The schematic structure of each part will be explained with reference to FIG. 1, which is a schematic perspective view of the main parts.The radiator bracket 1 includes a pair of plate-shaped support sections 5 extending upward along both side surfaces 3 of the vehicle body frame 2, and a coexistence column section 5. . ), and an arm 10 extending rearward from the upper end of the right (left side in the figure) support column 5. These members constituting the bracket 1 are welded together.

The radiator 11 placed on the bottom plate 6 is fixed to the support column 5 on both sides with bolts 12.

The arms 9 and 10 are fixed to the engine case (both not shown) by bolts inserted through holes 13 and 14 at the rear end.
An auxiliary plate 15 welded to the lower outer surface of the compatible pillar portion 5 is fixed to the side surface 3 of the vehicle body frame 2 with bolts 17.

The upper end of a plate-shaped reinforcing member 19 extending obliquely along the side surface 3 is welded to the upper part of the support column 5 on the right side of the figure, and the lower end of the member 19 is welded to the right end of the battery bracket 20 in the figure. .

The battery bracket 20 consists of l pairs of members located at intervals in the vehicle width direction, and each member is connected to the integral bottom wall 2.
1. A front wall 22 and a rear wall 23 are provided, and the bottom wall 21 is fixed to a horizontal member of the vehicle body frame 2 by bolts (not shown).
are spot welded at multiple locations.

35 is a battery.

As shown in FIG. 2, which is a partial front view, the reinforcing member 19 has a stepped portion 34 in the middle portion in the longitudinal direction, and outwardly bent portions 25 (facing right in the figure) formed at the lower end are formed at multiple locations on the bottom wall 21. spot welded.

As shown in FIG. 3, which is a partial plan view, the rear edge of the reinforcing member 19 (
An outward bent portion 26 is formed on the front edge (vertical edge) of the column 5, and an outward bent portion 27 is formed on the front edge (vertical edge) of the column 5, and multiple points are formed on the front surface of the horizontal member 7. spot welded.

Reference numeral 28 denotes a substantially auxiliary plate, which is spot-welded to the horizontal member 7 and the reinforcing member 19 at multiple locations.

In FIG. 4, which is a left side partial view, the support column 5 and the horizontal member 7 are fixed to each other via an auxiliary plate 30, and specifically, the front edge of the auxiliary plate 30 is welded to the horizontal member 7 over the entire length. The lower portion is spot welded to the outer surface of the support column 5 at multiple locations.

Note that the contact portion 31 (
(Fig. 2) is also welded.

In the present invention, the radiator bracket 1 is integrated with a bottom plate 6 fixed on the vehicle body frame 2, plate-shaped support portions 5 rising from both left and right edges of the bottom plate 6, and a horizontal member 7 connecting the upper ends of the compatible support portions 5. A bottom wall 21, on which the battery bracket 20 is fixed on the vehicle body frame 2 immediately in front of the radiator bracket, and front and rear walls 22 rising from the front and rear edges of the bottom wall 21.
23, and the battery bracket rear wall 2 is attached to a bent portion 24 that stands up from the front edge of the radiator bracket bottom plate 6.
3, and attach the upper part of only one of the radiator bracket support columns 5 to the side of the battery bracket 20 on the side corresponding to the upper part with a plate-shaped reinforcing member 19 along the vertical plane in the front-rear direction.
Because they are rigidly connected through the , the following special effects can be obtained.

That is, the mounting strength of the radiator bracket 1 is significantly improved compared to the case where only the lower end of the support column 5 is fixed to the vehicle body frame 2.

Moreover, since the reinforcing member 19 is provided only on one side of the battery bracket 20 (the right side in FIG. 1), the work of attaching and removing the battery 35 to and from the bracket 20 is performed on the side opposite to the reinforcing member 19 (the upper left side in FIG. 1). ) can be easily done.

Furthermore, according to the present invention, the radiator bracket 20 can be formed into an integral sheet metal structure using plate materials such as steel plates, so a lightweight and durable structure can be obtained, and moreover, there is sufficient storage space for the radiator 11 and battery 35. Can be secured.

Since the plate-shaped reinforcing member 19 is arranged on the side edge of the space along the vertical plane in the front-back direction, the thin material prevents the radiator bracket 1 from tilting back and forth, and also prevents the battery 3 from tilting.
This has the effect of not reducing the storage space of 5.

The lower front end of the plate-shaped reinforcing member 19 can be welded to the bottom wall 21 of the rubber terry bracket, so spot welding is possible because both are made of the same plate material, and there is no need to weld the member 19 to the thick vehicle body frame 2. Work becomes easier;
Radiator bracket 1 and battery bracket 20
The combined body can be manufactured in advance in a pre-process and the combined body can be fixed to the vehicle body frame 2, making it easy to manufacture the agricultural tractor.

Since the bottom plate 6 of the radiator bracket 1 is provided with a bent part at the front edge, the battery 35 placed just in front of the bent part and the bottom plate 6 work together to remove straw and dust kicked up by the wheels from below the frame to the radiator 11. This makes it difficult to reach the radiator 11, and clogging of the radiator 11 can be easily prevented.

The bent portion 24 is integrated with the rear wall 23 of the battery bracket to reliably prevent the battery 35 from moving backward, and is useful for making the battery bracket 20 thinner and lighter.
