Abstract
【解決手段】一対の軸受38、40の間に円筒形状のセパレータ46が配設されており、油供給口44から供給された潤滑油はセパレータ46によって受け止められるため、ドライブピニオン30の段付シャフト42等に潤滑油が直接付着して連れ廻りや攪拌等により発生する動力損失が低減される。また、セパレータ46によって受け止められた潤滑油は、両側の側壁48、50に設けられた連通孔52、54から所定の流量で一対の軸受38、40側へ流出して潤滑や冷却に用いられるため、必要以上の潤滑油が軸受38、40に供給されて粘性抵抗等により大きな動力損失が発生することが抑制され、全体として動力伝達効率が向上する。
【選択図】図2
Description
図1は、本発明が適用された軸受潤滑構造を備えている終減速装置20を有する前置エンジン後輪駆動(FR)形式の車両10の動力伝達機構を説明する図である。この図1において、車両10は、動力源であるエンジン12と、左右1対の前輪14L、14Rと、上記エンジン12の出力回転を変速するための自動変速機16と、その自動変速機16の出力軸から出力される駆動力を伝達するためのプロペラシャフト18と、後輪用駆動力分配装置として機能する終減速装置20と、その終減速装置20により分配された駆動力を伝達するための左右1対の後輪車軸22L、22Rと、その後輪車軸22L、22Rを介して駆動力が伝達される左右1対の後輪24L、24Rとを備えている。
