ドル取付け部構造に関する。[Detailed description of the invention] [Field of industrial application] This invention has a steering handle that can be tilted freely, a gate-shaped fuselage frame located in front of the control section when viewed from the front and back of the aircraft, and an engine fuel tank. The present invention relates to a handle attachment structure for an agricultural tractor in which a tank is attached to the body frame in such a manner that the rear end side thereof protrudes from the body frame toward the steering handle.

Conventionally, in the agricultural tractor described above, considering that the engine fuel tank does not have sufficient strength to support the steering handle due to its material, a handle support member for tiltably supporting the steering handle has been attached to the vehicle. It was connected to the frame.

In the case of the above-mentioned conventional structure, the handle support member must be formed so as to span the fuselage frame and the handle shaft located relatively far away from the fuselage frame, and the fuel tank must be formed so as to bypass it so as not to interfere with it. It was necessary to form the handle support member in a large size having a relatively long length and in a complicated shape.
本考案の目的は、ハンドル支持部材の小型化及
び簡素化ができるように改造することにある。 An object of the present invention is to modify the handle support member so that it can be made smaller and simpler.

The characteristic configuration of this invention is that the steering handle is tiltable, the gate-shaped fuselage frame is placed in front of the control section when viewed from the front and back of the aircraft, and the fuel tank for the engine is connected to the rear end of the steering handle from the fuselage frame. In the steering wheel attachment structure of an agricultural tractor that is attached to the body frame in a protruding state, a first steering wheel is attached to the steering wheel support member that supports the steering wheel so that the steering wheel can be tilted freely.
A seat surface and a second seat surface are provided, of the two walls sandwiching the tank corner on the rear surface of the fuel tank, the first seat surface is on the upward facing wall surface and the second seat surface is on the rearward facing wall surface. By connecting near the tank corner,
The fuel tank is characterized in that the handle support member is attached and supported at a corner portion at the rear of the fuel tank.
つまり、ハンドル支持部材を、機体フレームで
はなく、近くにある燃料タンクに取付ける手段で
ある。しかし、単純に取付けただけでは支持強度
に不安があるので、本願では、燃料タンク後部の
角部を挟む２壁面に亘つて取付けることで支持強
度を確保した。
In other words, it is a means of attaching the handle support member to a nearby fuel tank rather than to the fuselage frame. However, if the fuel tank is simply attached, there is a concern about the support strength, so in this application, the support strength is ensured by attaching the fuel tank across two wall surfaces that sandwich the rear corner of the fuel tank.
すなわち、薄肉の板材で構成される燃料タンク
は、通常はそれを強度部材としては使用しないの
であるが、タンク角部における強度・剛性は面部
に比べて改善される性質に着目し、ハンドル支持
部材を第１及び第２座面をしてタンク角部近くで
その角部を挟む２面に取付け支持させるようにし
た。これにより、燃料タンクが変形することなく
ステアリングハンドルを強度十分に支持すること
ができるとともに、燃料タンクがハンドル近くに
あることによつて、ハンドル支持部材は、タンク
後部とハンドルとを連結するだけの短尺で、か
つ、従来のように燃料タンクを迂回する必要のな
い形状簡単なもので良い。 In other words, fuel tanks made of thin-walled plates are not normally used as strength members, but we focused on the fact that the strength and rigidity at the corners of the tank are improved compared to the face parts, and developed a handle support member. The first and second seating surfaces are mounted and supported near the corner of the tank on two surfaces sandwiching the corner. This allows the steering wheel to be supported with sufficient strength without deforming the fuel tank, and since the fuel tank is located near the steering wheel, the steering wheel support member only connects the rear of the tank and the steering wheel. It may be short and have a simple shape that does not require bypassing the fuel tank like in the past.
加えて、ハンドル支持部材を燃料タンクに連結
することによつて燃料タンク自体を部分的に強度
アツプできるようにもなり、燃料タンクやハンド
ル支持部分の全体としての強度改善にも役立つよ
うになる。 In addition, by connecting the handle support member to the fuel tank, the strength of the fuel tank itself can be partially increased, which also helps to improve the overall strength of the fuel tank and the handle support part.
尚、単に燃料タンクにハンドル支持させるもの
としては、実願昭59−91432号（実開昭61−6465

られているが、このものでは燃料タンクの１つの
面のみでハンドル支持部材を支持しているので、
強度確保上、タンク板材が厚肉板材となつて重量

でのオーバーハングが長くなつて該取付部に作用
する応力が大きくなり易いチルト構造のハンドル
部の支持までは強度十分に行えないおそれが強
い。これに対し、本願のものではそのような不利
なく強度十分にして支持できる点で明らかに有利
である。 In addition, as for simply supporting the handle on the fuel tank, Utility Application No. 59-91432 (Utility Application No. 61-6465)
The one shown in the micro film of No. 1 (Japanese Publication) is known, but in this one, the handle support member is supported by only one side of the fuel tank, so
In order to ensure strength, the tank plate material becomes a thick plate material, which tends to increase the weight.In addition, as in the present application, the weight increases, and the overhang from the mounting part on the fuel tank surface to the handle becomes long. There is a strong possibility that the support for the handle portion of the tilt structure, where the stress acting on the handle portion tends to be large, may not be strong enough. On the other hand, the present invention has a clear advantage in that it can be supported with sufficient strength without such disadvantages.
その結果、タンク角部における強度改善の性質
を利用することと、ハンドル支持部材の連結構造
工夫とによつて、重量の重くなり易いチルト構造
のハンドル部の強度部材として燃料タンクを使用
することが可能になり、ハンドル支持部材を従来
より短尺で簡素に構成でき、ハンドルの支持強度
十分にしながらコストダウンできた。
As a result, by utilizing the property of improving the strength at the corner of the tank and devising the connection structure of the handle support member, the fuel tank can be used as a strength member for the handle part of the tilt structure, which tends to be heavy. This allows the handle support member to be shorter and simpler than before, reducing costs while providing sufficient support strength for the handle.
