Abstract
【解決手段】原動機と相対回動不能に結合するための駆動軸2が設けられており、該駆動軸が分配伝動装置12を介して無段変速機4の両軸14,16に結合されており、パラレルシフト伝動装置20が設けられており、該パラレルシフト伝動装置の複数の入力軸18,22が各1つのクラッチK13,K2Rを介して無段変速機4の各1つの軸と連結可能であり、パラレルシフト伝動装置の出力軸が、出力分岐された伝動装置の被駆動軸10を形成しており、少なくとも2つの変速範囲が、パラレルシフト伝動装置20の1つの入力軸とパラレルシフト伝動装置20の出力軸との間の変速比によってのみ互いに異なっている。
【選択図】図3
Description
a) 電気機械が制動固定された状態におけるD−走行範囲
クラッチR(後退クラッチ)は開かれていて、クラッチD(前進クラッチ)は閉じられている。ブレーキBがかけられており、すなわち結合軸6は停止している。こうして移動可能となる範囲は図18において符号「a」で際立たされている。この範囲は最小可能な変速比および最大可能な変速比を有している。
クラッチDが開かれていてかつクラッチRが閉じられている状態で、駆動軸102によって直接に無段変速機Varが駆動される。逆転は第2の遊星歯車伝動装置P2により行われる。
ブレーキBが開かれている状態で、ロックされた第1の遊星歯車伝動装置P1を介して出力分岐が行われる。第1の遊星歯車伝動装置P1のロック(Blockade)は、たとえばクラッチDおよびクラッチRを同時に操作することによって行うことができる。第2の遊星歯車伝動装置P2は合算伝動装置を形成する。こうして移動可能となった範囲は図18において符号「c」で示されている。伝動装置はこの場合、やはり最小変速比および最大変速比を有しており、この変速比は図18において、制動固定された電気機械を用いた走行範囲とは異なる範囲を占める。
停止状態における前進クリーピング時では、クラッチDにおいてクリーピングトルクの形成が行われ、これにより被駆動軸108においてフットブレーキに抗して作用するトルクが調節される。ブレーキBにおいてスリップが許容されると、クリーピングトルクが変えられていない状態でクラッチDに存在するスリップをブレーキBのスリップへ置き換えることができる。すなわち、クラッチDを閉じることができる。この状況では、ブレーキBにおけるスリップを直接にその操作を介して調節するか、または電気機械のジェネレータトルクを介して調節することが可能となる。クリーピングトルクが電気機械のジェネレータトルクによってのみ形成される場合には、内燃機関からジェネレータへの出力の流れが生ぜしめられ、この場合、被駆動軸108は支持のために働き、かつクリーピングトルクを維持する。
図示の伝動装置構造は、特別な無段変速機変速比においては次のような特性を有している。すなわち、駆動軸102と被駆動軸108との間で有効となる変速比、つまり伝動装置全体の変速比が、結合軸106の回転数、つまり電気機械の回転数とは無関係となる。図20には、伝動装置のこのような変速比において移動可能となる点が符号「e」で際立たされている。無段変速機Varの相応する変速比においては、ブレーキBによる伝動装置の支持は行われない。電気機械はこうして「論理的」にはその他の伝動装置部分から分離されている。すなわち、この変速比において走行すると同時に電気機械の回転数を合目的性に準じて制御ユニット120を介して調節することが可能となる。電気機械の回転数は遊星歯車伝動装置を介して無段変速機の回転数と、すなわち円錐形プーリ式巻掛け伝動装置の場合には円錐形プーリ対の回転数と、回転数比の維持下にカップリングされている。これによって無段変速機回転数を低下させることができる。これにより負荷が低下するか、もしくは巻掛け手段、たとえばリンクプレートチェーンの運転時間が向上する。図示の伝動装置構造では、結合軸106の回転数が伝動装置変速比に影響を与えなくなる無段変速機の変速比もしくは伝動装置全体の変速比が、高速道路でしばしば使用される最高ギヤ段の近傍にあり、すなわちチェーン損傷にとって重要な範囲にある。
電気機械の回転数を介して伝動装置の入力回転数を、所定の被駆動回転数において、制限された程度に変化させることができる。このことは車両の運転者にとっては、変速レンジの増大として感じられる。この効果を生ぜしめる運転点は図19に符号「f」で際立たされている。最小の変速比は一般にエンジンブレーキ運転時に必要とされるので、この場合には電気機械のアクティブな加速は必要とならず、車両は内燃機関および電気機械をも駆動する。すなわち、電気機械はそれと同時に変速レンジを向上させ、かつこのときにジェネレータ運転で作動する。変速レンジの同様の拡張は始動変速比において可能となる。
本発明による伝動装置を自体公知の形式で少なくとも1つの付加的なクラッチによって拡張して、連続的に調節可能な変速比を有する複数の変速範囲を備えた伝動装置を形成することができる。特に図7に示した伝動装置はこのような伝動装置を成している。その場合、伝動装置の全変速比と無段変速機の変速比とがクラッチの切換前と切換後とにおいて等しくなることにより、範囲チェンジ点もしくは範囲チェンジ変速比が規定されている。本発明による伝動装置では、範囲チェンジを実施するために電気機械を使用することができる。このような範囲チェンジは図19に符号「g」で際立たされた移行部に相当する。電気機械回転数の制御により、範囲チェンジを、クラッチにより制御される範囲チェンジの場合に可能となるよりも一層正確にコントロールすることができる。さらに、クラッチにより制御される範囲チェンジの場合には、常に出力が摩擦に変換され、この摩擦出力は電気機械の使用によって少なくとも部分補償され得るか、あるいは高められ得る。
駆動軸102の回転数と被駆動軸108の回転数とにより規定された各走行状態のためには、伝動装置の複数の無段調節可能な運転パラメータ、たとえば無段変速機Varの変速比および電気機械の回転数が存在している。これによって、たとえばエンジンブレーキ運転において無段変速機調節により電気機械の回転数を高め、かつこれによりエネルギ回収を増大させることが、外部に対しては「目に見えないように」可能となる。この過程は、運転者がブレーキペダルを操作する際の力Kにより制御することができる。さらに、運転者の出力意志が少しだけ変化した場合に、内燃機関の消費量にとって好都合な回転数および消費量にとって好都合な運転点を維持し、かつ差出力を電気機械により制御することが可能となる。このことは、慣用のジェネレータに対する利点となる。なぜならば、発電が意図的に、内燃機関の消費量にとって好都合な運転点において行われ得るからである。
伝動装置の位置Pにおいて内燃機関を始動させるために、本発明による伝動装置を用いて、特にアクチュエータ112,114,116,118にエネルギを供給するハイドロリック装置が作動するまで電気機械を始動させることが可能である。ハイドロリックポンプ(図示しない)は、たとえば2つのフリーホイールを介して択一的に電気機械によるか、または内燃機関によって駆動され得る。電気機械が作動すると、クラッチDを連結するか、または両クラッチD,Rを連結することにより内燃機関を始動させることができる。伝動装置が図21に示したような構造を有していると、電気機械と結合軸との間の1つのクラッチにおいても、内燃機関を連行する連結過程を行うことができる。
A:電気機械と結合軸106との両方が制動固定されている;
B:電気機械と結合軸106との両方が互いに別個に独立して自由に回転可能である;
C:電気機械と結合軸106とが第1の変速比にあり、しかし両者が一緒に回転可能である;
D:電気機械と結合軸106とが第2の変速比(別の値および/または別の正負符号を有する)にあり、しかし両者が一緒に回転可能である。
