Description
変速機入力軸が入力ディスク駆動軸に対して角度が変化可能であることが好ましい。
変速機入力軸と入力ディスク駆動軸との間に、軸受手段、例えばスラスト軸受が配置されることが好ましい。
変速機が、変速機入力軸に加えられる入力トルクに比例する、第1の端部荷重を出力ディスクに加えるため、変速機入力軸の端部と出力ディスクとの間に、ボールおよび傾斜路結合部をさらに備えることができる。
変速機が、入力トルクを入力ディスク駆動軸に伝達するため、入力ディスク駆動軸に結合されたスプライン加工されたスリーブをさらに備えることができ、スプライン加工されたスリーブがボールおよび傾斜路結合部の部分を形成する。
スプライン加工されたスリーブが肩部を備えることができる。
別の実施形態では、第1の端部荷重および第2の端部荷重が入力ディスクに加えられる。
ばね手段の使用は、例えば、入力ディスクおよび出力ディスクの一方が作動中に実質的に一定のトルクを受けることが期待される状況では、適切であることがある。ばね(例えば、ばね座金)の使用は、変速機の複雑さおよび費用をかなり減少させることができる。
出力ディスクと環状変速機出力要素との間にボールおよび傾斜路結合部がさらに存在することが好ましい。
傾斜路が環状出力要素内および出力ディスクの外側面内にあることが好ましい。
軸受手段、例えばスラスト軸受が、環状出力要素と変速機入力軸との間に配置されることができる。
例示としてのみ、本発明の具体的な実施形態が添付の図面を参照してここで説明される。
したがって、一方は入力トルクに比例し、一方が出力トルクに比例する2つの独立した端部荷重構成要素が、同じディスク、すなわち出力ディスク12に加えられる。このように、バリエータに加えられた端部荷重が入力トルクおよび出力トルクの合計に比例し、したがって高圧油圧システムを必要とせずに、正確な端部荷重が機械的に提供される。
例えば、説明された実施形態は出力トルクに加えられる2つの端部荷重を有するが、もし所望されれば、その代わり、両方の端部荷重が入力ディスクに加えられることが可能であろう。
