Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は農用トラクタ等に用いられるものであって、エ
ンジンを３個以上の防振ゴムで支持するエンジンの支持
構造に関する。The present invention relates to an engine support structure for use in agricultural tractors and the like, in which the engine is supported by three or more anti-vibration rubbers.
この種のエンジンの支持構造において、防振ゴムを選定
するに、エンジンの重心位置が中心に位置する場合は少
ないので、防振ゴムをエンジンの中心位置を中心として
左右前後に振り分けて配置したとしても各防振ゴムに作
用する分担荷重は異なったものになる。In this type of engine support structure, when selecting the anti-vibration rubber, it is rare that the center of gravity of the engine is located at the center. However, the shared load acting on each anti-vibration rubber is different.
したがって、各防振ゴムのエンジンに対する支持姿勢を
同一にすれば、各分担荷重の大小に対応したバネ特性の
異なる防振ゴムを選定するのが理想であるが、それでは
種類が多くなって、コスト面で不利である。Therefore, it is ideal to select anti-vibration rubbers with different spring characteristics corresponding to the size of each shared load, provided that the anti-vibration rubbers have the same support posture with respect to the engine. It is disadvantageous.
本発明の目的は防振ゴムの設定姿勢に工夫を凝らして、
コスト面で有利に展開できるものを提供する点にある。The purpose of the present invention is to devise an anti-vibration rubber setting posture,
The point is to provide a product that can be advantageously developed in terms of cost.
本発明による特徴構成は、 防振ゴムのエンジンに対する支持軸心における上方へ
の延長仮想線を、鉛直線に対して傾斜させる点と、 各防振ゴムの分担荷重が大きいもの程鉛直方向線と延
長仮想線とのなす鋭角傾斜度を小さく設定してある点
と、 にあり、その作用効果は次の通りである。The characteristic configuration according to the present invention is such that the upward imaginary line of the vibration isolating rubber supporting shaft center for the engine is inclined with respect to the vertical line, and that the larger the shared load of each anti-vibration rubber is, the vertical direction line is formed. There is a point that the acute-angle inclination formed by the extension virtual line is set to be small, and the action and effect are as follows.
特徴構成より、防振ゴムの取付姿勢は鉛直方向に対し
てエンジン重心側に傾斜し、上下方向の加振力及び水平
方向の加振力に対して支持力を発揮できる姿勢に設定し
てある。しかも、特徴構成より、分担荷重（つまり、
エンジン重量＋上下方向加振力の分担分）の大きいもの
程傾斜度合を小さくして、縦姿勢に近い状態に設定し、
鉛直方向への支持分力を大きくしている。Due to the characteristic structure, the mounting position of the anti-vibration rubber is inclined to the center of gravity of the engine with respect to the vertical direction, and is set to a position capable of exerting a supporting force against the vertical and horizontal vibration forces. . Moreover, the shared load (that is,
The larger the engine weight + the contribution of the vertical excitation force), the smaller the degree of inclination, and the closer to the vertical position,
Support force in the vertical direction is increased.
したがって、耐荷重の異なる防振ゴムを用意する必要は
なく、同一特性仕様の防振ゴムを揃えればよい。Therefore, it is not necessary to prepare anti-vibration rubbers having different withstand loads, and anti-vibration rubbers having the same characteristic specifications may be prepared.
その結果、大量購入の利点が生かされて製造コスト面で
有利であり、その為の改造も防振ゴムの取付姿勢を変え
るだけの簡単なものでよい。As a result, the advantage of mass purchase is utilized, which is advantageous in terms of manufacturing cost, and modification for that purpose can be as simple as changing the mounting posture of the anti-vibration rubber.

てある。The support structure of the engine will be described with reference to an example of an agricultural tractor. As shown in Fig. 2, the engine bonnet
Inside the (1), the engine vibration-isolated and supported by the fuselage frame (2)
(3), equipped with radiator (4) and air cleaner (5) on the operating side from engine (3), and muffler (6) and battery (7) above engine (3) to install the front structure of the agricultural tractor. I am configuring. Cooling air is taken in here through cooling air intakes (9) provided on both side walls of the bonnet (1), and this air is made to act on the radiator (4) and discharged from the front of the engine (3). However, the hot air does not act on the worker.

鋭角傾斜度（θ１），（θ２）が、右の防振ゴム(8B)程
小さいものに設定してある。As shown in FIG. 1, the engine (3) is provided with a pair of front and rear anti-vibration rubbers (8) on the left and right sides, respectively, for anti-vibration support. These anti-vibration rubbers (8) are in a state where the imaginary lines (a) and (b) extending upward in the support shaft center for the engine (3) are inclined obliquely upward toward the center of gravity of the engine (3). is set up. The left anti-vibration rubber (8A) and the right anti-vibration rubber (8B) are set such that their support axes have different inclinations, and the right anti-vibration rubber (8B) has a load sharing ratio. Since it is large, the acute angle inclinations (θ 1 ) and (θ 2 ) formed by the extension virtual lines (a) and (b) and the vertical lines are set to be as small as the right anti-vibration rubber (8B). is there.
