JPS60996Y2 - Structure of the headlamp bracket attached to the bonnet - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to the structure of a headlamp bracket attached to the bonnet of an agricultural tractor.

Generally, the headlamps of agricultural vehicles are installed in the front end of the bonnet itself or in the headlamp mounting hole in the upper panel that is integrally fixed to the front end of the bonnet, but headlamp standards differ depending on where it is used. In this case, bonnets with different shapes and sizes of headlamp mounting holes must be prepared, making inventory management and assembly work time-consuming.

Agricultural tractors are not only used domestically but also exported overseas; for example, in France, there is a regulation that headlamps used must be made from locally sourced materials.

To meet this requirement, it is convenient to share headlamp brackets as much as possible.

This invention prepares several types of headlamp brackets that have mounting holes for different types of headlamps and a common structure for the mounting part to the bonnet, and one of them can be used for different purposes.
It is characterized by the fact that it can be replaced and attached to the headlamp bracket attachment part (common size) of the bonnet depending on the destination, etc., and will be explained next with reference to the drawings.

No. 1 showing the longitudinal left side of an agricultural tractor to which the present invention is applied.
In the figure (arrow F indicates the front), the bonnet 1 is supported by a front axle bracket 3 via a hinge pin 2 at the lower front end and can be opened and closed in the direction of the arrow A.

The front axle bracket 3 is a member that is fastened to the left and right side walls of an engine (not shown) with a plurality of bolts and protrudes forward from the engine (to the left in FIG. 1).

A headlamp bracket 4 is fixed to the front upper part of the bonnet 1 with bolts 5 and nuts 6.

The headlamp bracket 4 is a sheet metal member that is long in the left-right direction as shown in FIG. Fit the hole of the bending piece 8 into the welding bolt 5 fixed to the bracket attachment part 9 of the bonnet 1 as shown in Figure 9 from the inside. It is fastened to the side attachment part 9.

The headlamp bracket 4 shown in FIG. 2 is for France, and a headlamp 11 made by Haruji is fitted into the headlamp mounting hole 7 from the front and fixed with a plurality of bolts.

That is, the hole 7 is previously provided in the headlamp bracket 4 to match the dimensions and size of the original headlamp 11, and this headlamp bracket 4 is installed on the bonnet in common with the headlamp bracket for domestic use, which will be described later. (the bending piece 8 and the insertion hole for the bolt 5, etc.).

The headlamp bracket 4' shown in Fig. 4 is for domestic use, and is equipped with a headlamp mounting hole 7' suitable for mounting a domestically manufactured headlamp 11'.
In order to attach it to the common bonnet 1, it is provided with a bending piece 8 having the same position and shape as the headlamp bracket 4 shown in FIG.

If the destination is known in advance, a headlamp bracket corresponding to the destination is attached to the bonnet 1 on the assembly line.

At that time, by slightly deforming the left and right bent pieces 8 of the headlamp bracket 4, the holes of the bent pieces 8 can be fitted into the welding bolts 5 on the bonnet side.

To remove the headlamp bracket 4 shown in Figures 1 and 2, remove the two nuts 6 and washers 10 on both the left and right sides, slightly deform the bent piece 8, and open the bolt insertion hole on the bent piece 8. Just remove it from bolt 5.

When attaching the headlamp bracket 4' shown in FIG. 4, the above operation may be performed in reverse.

As explained above, in the present invention, the headlamp bracket 4 has mounting holes 7 (or 7') for different types of headlamps and has a common structure for mounting to the bonnet 1.
(or 4') can be replaced and installed on the headlamp bracket mounting part 9 of the bonnet 1, so when exporting the tractor to a country that has regulations that require the headlamp used to be made of thick material, the Even if a headlamp bracket with specifications corresponding to the vehicle is shipped separately, it can be replaced with a thick bonnet.Also, if the destination is known in advance, a headlamp bracket according to the destination can be installed on the assembly line. The advantage is that the large-sized bonnet 1 can be shared by all models, and only a few types of small-sized headlamp brackets need to be prepared, which simplifies parts management and assembly work, and reduces costs. be.
