Description
図1は、本発明の一実施形態に係る自動変速機1を搭載した車両の動力伝達系(以下「駆動系」という)Pの全体構成を概略的に示している。
エンジンENGおよび自動変速機1の動作は、エンジンコントローラECU、変速機コントローラ9により夫々制御される。エンジンコントローラECUおよび変速機コントローラ9は、いずれも電子制御ユニットとして構成され、中央演算装置(CPU)、RAMおよびROM等の各種記憶装置、入出力インターフェース等を備えたマイクロコンピュータからなる。
図2は、本実施形態に係る自動変速機1の全体構成を概略的に示している。
図3は、自動変速機1に備わるねじ送り機構35、45の構成を示している。図3(a)は、プライマリプーリ3側のねじ送り機構35を示し、同図(b)は、セカンダリプーリ4側のねじ送り機構45を示している。
以上で述べたように、本実施形態によれば、変速用の電動モータ(変速モータ7)に加え、ベルトクランプ用の電動モータ(クランプモータ8)を設置したことで、皿バネ等を用いるこれまでの自動変速機とは異なり、ベルトクランプ力を適切に形成し、ベルトフリクションを低減することが可能となる。
