本考案は多気筒多弁式内燃機関における動弁装
置の締付構造に関する。[Detailed Description of the Invention] The present invention relates to a tightening structure for a valve train in a multi-cylinder, multi-valve internal combustion engine.
近年エンジンの高出力化を狙う為に吸入効率・
排気効率向上を計り、１つのシリンダに対し吸気
弁、排気弁を夫々２つずつ設ける等のように多弁
化し、動弁系が複雑化する傾向にある。 In recent years, in order to increase engine output, intake efficiency and
In order to improve exhaust efficiency, there is a tendency for valve systems to become more complex, such as by providing two intake valves and two exhaust valves for one cylinder.
一方、複雑化し動く部材の多い動弁系において
は受ける反力も大きく、それだけ十分にシリンダ
ヘツドへ固定しおく必要があるが、動弁系が複雑
化すればシリンダヘツド上には必然的に余裕空間
が不足し、斯かる固定用スペースを確保し難い。 On the other hand, in a valve train system that is complicated and has many moving parts, the reaction force received is large, so it is necessary to fix the valve train sufficiently to the cylinder head. It is difficult to secure such fixing space.
特に、吸、排気弁の一方の弁へ片寄せしてシリ

ず、気筒数が増えカムフオロアやロツカアームの
取付く数が多くなるほどこれら支軸の受ける反力
も大きく、十分な取付強度で締付け固定し難い。 In particular, when a single camshaft is provided to the cylinder head with one of the intake and exhaust valves biased toward the other, and the other of the intake and exhaust valves is opened via a cam follower, push rod, and rocker arm. It is desirable to arrange the center of the cam surface of the camshaft, the cam follower, and the push rod on the same straight line to allow these members to move smoothly and prevent uneven wear. The distance between the push rods disposed in the cylinder becomes narrower in accordance with the distance between the cam portions of the camshaft, and in the case where a plurality of the other valves are provided, the distance between the push rods becomes very narrow. Therefore, when the support shaft of the cam follower or the rocker arm is tightened and fixed with a tightening bolt, the head of the bolt interferes with the valve operating member such as the push rod at the location between the push rods, making it difficult to tighten and fix the support shaft at the location between the push rods. However, as the number of cylinders increases and the number of cam followers and rocker arms that are attached increases, the reaction force that these support shafts receive increases, making it difficult to tighten and fix them with sufficient mounting strength.
