【考案の詳細な説明】
本考案は、例えば前後輪を油圧駆動すべく構成しである
フレーム式トラクタのように、フレーム上にエンジンを
緩衝材を介して固定支持させ、前記エンジン後部に油圧
ポンプをオーバーハング状態に直結しである移動農機に
おけるエンジン支持装置に関する。[Detailed Description of the Invention] The present invention is such that, for example, in a frame-type tractor configured to hydraulically drive the front and rear wheels, an engine is fixedly supported on the frame via a cushioning material, and a hydraulic pump is mounted at the rear of the engine. This invention relates to an engine support device for a mobile agricultural machine that is directly connected to an overhang state.

効果を期待できないものである。When supporting the engine alone with vibration isolation on the frame, by arranging cushioning materials at multiple locations equally or almost equally spaced from the center of gravity of the engine, it is possible to achieve efficient vibration isolation while making the design relatively simple. Although the effect can be distantly related,
In the case where the hydraulic pump is directly connected to the engine in an overhanging manner as described above, the overall center of gravity of the engine deviates from the center of gravity of the engine alone, so the anti-vibration support structure for the engine alone as described above In addition to the static loads applied to the cushioning materials at multiple locations, there is a large imbalance in the distribution of dynamic loads due to engine vibration, and this also causes some of the cushioning materials to wear out quickly. Appropriate anti-vibration effects cannot be expected.

造改造が余儀なく必要となる。Therefore, it is conceivable to support the entire engine and hydraulic pump on the frame via cushioning materials placed at multiple appropriate locations so that the entire load is equally or almost equally distributed, but in this case, In order to support the bottom of the hydraulic pump, which is directly connected to the engine in an overhanging manner, it is necessary to erect and connect an appropriate support member to the frame. Extensive structural modifications are unavoidably necessary, such as requiring a structure based on a severe design that prevents undue stress from concentrating at the point where it is directly connected.
本考案はかかる問題に鑑みたもので、頭記構成のものに
おいて、前記エンジンに直結の油圧ポンプをフレームに

部材を設けであることを特徴とする。The present invention has been developed in view of such problems, and is characterized in that the above structure is provided with a member that elastically supports the hydraulic pump directly connected to the engine by tensioning the frame from above and below and from left and right. do.

を現出できるに至った。In other words, the present invention considers the vibration isolation effect for the hydraulic pump separately from the vibration isolation effect for the engine, and since it is not directly supported by the frame (it is in a floating state with respect to the frame), The hydraulic pump, which tends to vibrate, can be supported by the elastic tension support member under an appropriate vibration isolation state, and the elastic force and position of the tension support member are controlled in accordance with those of the shock absorber relative to the engine. It can be easily determined independently from the engine, and the cushioning material for the engine only needs to be provided by considering the center of gravity of the engine, as in the past, and such a cushioning material provides sufficient protection against the engine. Because I can,
Overall, with a relatively simple design and structure, it has been possible to achieve great vibration isolation effects for the entire engine and hydraulic pump.
