【発明の属する技術分野】
本発明はトラクタや運搬車など作業車のエンジン装置に関する。
【0002】
【従来の技術】
エンジンの支持フレームを防振ゴムなど防振部材を介し車体フレームに防振支持させた構造のものがある。(例えば特許文献1参照)
【0003】
【特許文献1】特開2003−21160
【0004】
【発明が解決しようとする課題】
しかし乍らこのような従来手段の防振支持構造にあっては、防振部材は支持フレームと車体フレーム間の限定されたスペースに組込む必要があるばかりでなく、エンジンの一定以上の動きを規制するストッパを支持フレームと車体フレーム間に別途設けるなどの構造上の複雑さがある。
【0005】
【課題を解決するための手段】
したがって本発明は、エンジンの下部に固設するステーを防振部材を介し車体フレームに支持させた作業車のエンジン装置において、前記ステーを臨ませる切欠部を車体フレームに形成して、車体フレームの切欠部内の自由位置に防振良好にステーを臨ませる状態とさせて、エンジンの防振支持構造の簡単化を図るものである。
【0006】
また、エンジンの一定以上の動きを規制する隙間を車体フレームと切欠部との間に形成させて、エンジンの動きを規制するストッパの別途設置など必要とさせることなく、車体フレームの切欠部によるステーの規制でストッパの代用とさせて、従来のストッパ部品を削減させ、エンジンの防振機能を有効に向上させるものである。
【0007】
【発明の実施の形態】
以下、本発明の実施例を図面に基づいて詳述する。図1は全体の側面図を示し、図中1はトラクタであり、エンジン2を内設させるボンネット3両側に左右の前輪4・4を装設させ、前記ボンネット3後部に丸形操向ハンドル5を設け、該ハンドル5後方に運転席6を配置させ、運転席6両側外方に左右の後輪7・7を装設させる。
【0008】
図2乃至図5に示す如く、エンジン2の下部8の左右側面に断面門形状で左右方向に長手状のステー9基端の固着板10をボルト11止め固定させ、エンジン2の下部8の左右両側で前後方向に配設する車体フレーム12の上側切欠部13に溶接固定する防振受台14に防振ゴムなど円柱形防振部材15を介し前記ステー9を支持させるように設けている。
【0009】
前記防振部材15は下端を防振台16に固設させ、前記防振受台14にボルト17を介し防振台16を固定させると共に、円柱形防振部材15の上面中央のボルト18を係合孔19を介しステー9上方に突出させナット20によりステー9に固定させている。
【0010】
また前記防振受台14は車体フレーム12の切欠上面12aに水平状に溶接固定させ、図5に示す如く、ステー9の前後巾Aより切欠部の前後切欠巾Bを大(B>A)に形成し、ステー9の前後側面9aと車体フレーム12の切欠側面12bとの間にエンジン2の移動許容隙間Cを形成させ、エンジン2が振動などで大きく移動するときには、ステー9を車体フレーム12の切欠側面12bに当接させ振れ止め用のストッパとして作用させて、エンジン2の一定以上の移動を規制するように構成している。
【0011】
またこの場合切欠き部13の切欠き深さを大小に変更させることによって、防振部材15の取付高さ位置も任意位置に変更可能とさせて、防振支持位置に制約を受けることのない自由度の高いエンジン2の良好な防振支持を行うことができる。
【0012】
【発明の効果】
以上実施例から明らかなように本発明は、エンジン2の下部8に固設するステー9を防振部材15を介し車体フレーム12に支持させた作業車のエンジン装置において、前記ステー9を臨ませる切欠部13を車体フレーム12に形成したものであるから、車体フレーム12の切欠部13内の自由位置に防振良好にステー9を臨ませる状態とさせて、エンジン2の防振支持構造の簡単化を図ることができるものである。
【0013】
また、エンジン2の一定以上の動きを規制する隙間Cを車体フレーム12の切欠部13とステー9との間に形成させたものであるから、エンジン2の動きを規制するストッパの別途設置など必要とさせることなく、車体フレーム12の切欠部13によるステー9の規制でストッパの代用とさせて、従来のストッパ部品を削減させ、エンジン2の防振機能を容易に向上させることができるものである。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an engine device of a work vehicle such as a tractor or a transport vehicle.
[0002]
[Prior art]
2. Description of the Related Art There is a structure in which a support frame of an engine is supported on a vehicle body frame through vibration isolation members such as vibration isolation rubber. (For example, see Patent Document 1)
[0003]
[Patent Document 1] JP-A-2003-21160
[0004]
[Problems to be solved by the invention]
However, in such a conventional anti-vibration support structure, not only must the anti-vibration member be installed in a limited space between the support frame and the vehicle body frame, but also the movement of the engine beyond a certain level is restricted. There is a structural complexity such as providing a separate stopper between the support frame and the body frame.
[0005]
[Means for Solving the Problems]
Therefore, the present invention provides an engine device for a work vehicle in which a stay fixed to a lower portion of an engine is supported on a body frame via a vibration isolating member, wherein a cutout portion facing the stay is formed in the body frame, and The purpose of the present invention is to simplify the structure of the engine to support the anti-vibration by allowing the stay to face the free position within the notch portion with good anti-vibration.
[0006]
In addition, a gap for restricting the movement of the engine beyond a certain level is formed between the body frame and the notch, so that there is no need to separately install a stopper for restricting the movement of the engine. In this case, conventional stopper parts are reduced and the vibration damping function of the engine is effectively improved.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a side view of the entirety, in which 1 is a tractor, in which left and right front wheels 4, 4 are mounted on both sides of a hood 3 in which an engine 2 is installed. The driver's seat 6 is disposed behind the steering wheel 5, and left and right rear wheels 7.7 are provided outside both sides of the driver's seat 6.
[0008]
As shown in FIGS. 2 to 5, a fixing plate 10 at the base end of a stay 9, which has a gate-shaped cross-section and is formed in the left-right direction, is fixed to the left and right side surfaces of the lower portion 8 of the engine 2 by bolts 11. The stay 9 is provided on a vibration-proof pedestal 14 which is welded and fixed to the upper notch 13 of the vehicle body frame 12 provided on both sides in the front-rear direction, via a column-shaped vibration-proof member 15 such as vibration-proof rubber.
[0009]
The lower end of the anti-vibration member 15 is fixed to the anti-vibration base 16, and the anti-vibration base 16 is fixed to the anti-vibration pedestal 14 via a bolt 17. It protrudes upward from the stay 9 via the engagement hole 19 and is fixed to the stay 9 by a nut 20.
[0010]
Further, the anti-vibration pedestal 14 is horizontally welded and fixed to the notch upper surface 12a of the body frame 12, and as shown in FIG. 5, the front and rear width A of the cutout portion is larger than the front and rear width A of the stay 9 (B> A). When the engine 2 moves largely due to vibration or the like, the stay 9 is moved to the body frame 12 to form a movement allowable gap C between the front and rear side surfaces 9a of the stay 9 and the cutout side surface 12b of the body frame 12. , And acts as a stopper for steadying, thereby restricting movement of the engine 2 beyond a certain level.
[0011]
Further, in this case, by changing the notch depth of the notch portion 13 to be large or small, the mounting height position of the vibration isolating member 15 can be changed to an arbitrary position, and the vibration isolating support position is not restricted. Good vibration isolation support of the engine 2 having a high degree of freedom can be performed.
[0012]
【The invention's effect】
As is apparent from the above embodiments, the present invention is directed to an engine device of a working vehicle in which a stay 9 fixed to a lower portion 8 of an engine 2 is supported on a vehicle body frame 12 via a vibration isolating member 15. Since the notch 13 is formed in the body frame 12, the stay 9 is allowed to face the free position within the notch 13 of the body frame 12 with good vibration isolation, thereby simplifying the vibration isolation support structure of the engine 2. Can be achieved.
[0013]
Further, since the gap C for restricting the movement of the engine 2 beyond a certain level is formed between the notch 13 of the body frame 12 and the stay 9, it is necessary to separately install a stopper for restricting the movement of the engine 2. Instead, the stopper can be used instead of the stopper by regulating the stay 9 by the notch 13 of the vehicle body frame 12, so that the conventional stopper parts can be reduced and the vibration isolating function of the engine 2 can be easily improved. .
