Description

そして、エンジンフード14内のエンジンルーム46内に搭載された前記の後傾した4サイクルエンジン16は、図1〜図8に示すように、下部のクランクケース58底部がオイルパン16aになっており、オイルパン16a内には、オイル吸上げ口にオイルストレーナ16bが収容されている。
また、前記エンジンクランクケース58上部のシリンダ24内で上下往復動するピストン24aの運動が、コネクティングロッド58aを介してクランク軸22の回転運動に変換される。
そして、シリンダ24上部に設けられたシリンダヘッド26には、シリンダ24内燃焼室に繋がる吸気ポート28・排気ポート36を開閉する吸気弁60a・排気弁62とその動弁機構60b・62bが配設されている。
このように、実施形態のエンジンは、ダブルオーバヘッドカム型の4サイクルエンジンである。
The bottom of the lower crankcase 58 is an oil pan 16a, as shown in FIGS. 1 to 8, in the case of the above-described back-tilted four-stroke engine 16 mounted in the engine room 46 in the engine hood 14 An oil strainer 16b is accommodated in the oil suction port in the oil pan 16a.
Further, the motion of the piston 24a reciprocating up and down in the cylinder 24 above the engine crankcase 58 is converted to the rotational motion of the crankshaft 22 through the connecting rod 58a.
Then, the cylinder head 26 provided in the cylinder 24 top, intake valve 60a and exhaust valve 62 a and the valve mechanism 60b, 62b for opening and closing the intake port 28 and exhaust port 36 leading to 24 the combustion chamber cylinder arrangement It is set up.
Thus, the engine of the embodiment is a double overhead cam type 4-cycle engine.

クラッチ装置82は、エンジンクランク軸出力端に設置されたドライブクラッチプーリ82aと、クローラ用ドライブスプロケット軸84におけるスプロケット84aの反対端に設置されたドリブンクラッチプーリ82bと、断面V字形状のVベルト8cとからなるVベルト変速装置を兼用したものである。 The clutch device 82 includes a drive clutch pulley 82a installed at the engine crankshaft output end, a driven clutch pulley 82b installed at the opposite end of the sprocket 84a in the crawler drive sprocket shaft 84, and a V-belt 8 having a V-shaped cross section. it is obtained by combined an V-belt transmission comprising a 2 c.
