係り、特にエンジン振動を有効に吸収するようにした防
振用エンジン懸架装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a so-called link mount type engine suspension system that pivotally connects an engine to a vehicle body through a link, and in particular to a vibration-proofing system that effectively absorbs engine vibrations. It relates to an engine suspension system.
自動二輪車等において、エンジンを車体側に懸架する方
式としてジノ５−マウント方式、リンクマウント方式等
が従来から採用されている。BACKGROUND ART In motorcycles and the like, the Zino 5-mount method, link mount method, and the like have been adopted as methods for suspending the engine on the vehicle body side.
上記リンクマウント方式はエンジンを互いに略平゛行に
配設された複数のリンクを介して車体側に枢着連結し、
エンジンがその加振方向に変位し得るように構成し、エ
ンジン振動の車体側への伝播を遮断しようとするもので
ある。The above link mount method pivots and connects the engine to the vehicle body through a plurality of links arranged substantially parallel to each other.
The engine is constructed so that it can be displaced in the direction of vibration, and is intended to block the propagation of engine vibrations toward the vehicle body.
しかしながら、この種リンクマウント方式にあっては、
各リンクのエンジン側及び車体側連結部にゴムブツシュ
を介設していたため、車体左右方向の剛性、即ち横剛性
が低（なりがちであった。However, in this type of link mounting method,
Because rubber bushings were interposed at the engine-side and vehicle-side connecting portions of each link, the rigidity in the left-right direction of the vehicle body, that is, the lateral rigidity, tended to be low.
このため加振方向以外の他の方向にもエンジンが変位し
、車体側へのエンジン振動の伝播を効果的に遮断するに
は制約が多かった。For this reason, the engine is displaced in directions other than the vibration direction, and there are many restrictions on effectively blocking the propagation of engine vibrations to the vehicle body.

提供するにある。In view of the above-mentioned problems with this type of engine suspension system, the present inventor has created the present invention in order to effectively solve the problems.
The purpose of this is to increase the lateral rigidity by arranging bearings and rubber bushings in parallel in the thickness direction of at least one of the engine side connection part and the vehicle body side connection part of each link that suspends the engine. It is an object of the present invention to provide a vibration-isolating engine suspension system that suppresses engine displacement in directions other than the vibration direction, thereby effectively blocking the propagation of engine vibrations to the vehicle body side.
