Description

[Detailed Description of the Invention] This invention relates to a reinforcing frame for reinforcing the area around the engine of a tractor.

In conventional tractors, mounting seats are provided on the outside of the crankcase of the engine or on the outside of the clutch housing, and various attachments are attached to these mounting seats.

However, in recent years, tractors have become larger, and in the case of small tractors, the outer part of the engine part was immediately the outer part of the tractor body, but in the case of large tractors, the width of the engine and clutch housing did not increase as the width of the machine body increased. The mounting seats for attaching various attachments were left inside, so a bracket was provided that protruded outward from the inner mounting seat, and the attachments were attached to the tip of this bracket. In addition, problems such as the load acting on the attachment acting directly on the mounting seat and damaging the wall of the engine crankcase or clutch housing case where the mounting seat is installed, or damage to the front surface of the front part of the engine body. In the case of tractors with an axle bracket mounted on the axle bracket as the mounting surface, there is a problem that the mounting bolt of the axle bracket becomes distorted due to the bending and torsional forces that are applied to the mounting bolt of the axle bracket in an impact through the front wheel and the axle bracket. was.

In order to eliminate such defects, the present invention takes the following technical measures. That is, the engine body 1 is attached to the front end of the clutch housing 2 via the mounting plate 3.
A gearbox 12 is attached to the rear end, and brackets 5 for supporting a vertical frame such as a safety frame are provided on both sides of the mounting plate 3 to protrude outward. and the axle bracket 6 attached to the front surface.
The engine frame of the tractor is constructed by connecting and fixing the side parts of an engine body 1 with a side frame 7 extending in the front and rear direction.

This invention has the following technical effects due to the above configuration. That is, when an unexpected load is applied to the vertical frame of the safety frame 4, cabin frame (not shown), front loader (not shown), etc., the bracket 5 is moved and the load is applied to the mounting seat of the mounting board 3. However, since the bracket 5 and the axle bracket 6 are connected and fixed by the side frame 7 so as to sandwich the engine body 1, the load acting on the bracket 5 simultaneously acts on the axle bracket 6 and the load is distributed. Therefore, the impact load is not locally concentrated on one mounting part as in the conventional case, and the casting parts of the clutch housing and the crankcase wall are not damaged. Furthermore, since the bending and torsional forces that impactively act on the axle bracket 6 through the front wheel 9 are dispersed through the side frame 7, the mounting bolts that attach the axle bracket 6 to the engine body 1 are not distorted. can be prevented.

In the illustrated example, 8 is a bonnet that covers the engine body 1, 9 is a front wheel, 10 is a handle for changing the direction of the front wheel, 11 is a seat for the driver, 12
is the gearbox, 13 is the rear wheel, 14, 14...
1 is a mounting seat for attaching an attachment provided on the outside of the wall of the crankcase or clutch housing 2 of the engine body 1, 15, 15... is a mounting seat provided on the side frame 7, and 16 is a mounting seat for rotating the safety cover 17 outward. It is a removably attached hinge.

In this way, the safety cover 17 is pivotably attached to the upper surface of the strong side frame 7 that extends from the front and rear sides of the engine body 1, so that the safety cover 17 can be pivoted and detached freely. It can cover the uneven parts of hydraulic pumps, generators, starter motors, etc. In addition, mounting seats 14 and 15 for attaching attachments facing outward are provided on the outer side of the strong side frame 7 and the outer side of the engine body 1, so that it is possible to directly attach attachments across these two members. becomes. In addition, a strong side frame 7 extends from the front and rear sides of the engine body 1.
Since they are connected together, the load applied to the crankcase itself at the bottom of the engine body 1 is dispersed, and the crankcase wall does not become unnecessarily thick.
