Abstract
Description
図1に本発明の一実施形態によるクラッチカバー組立体1の正面図を示す。また、図2にクラッチカバー組立体1の一部を破断するとともに一部の部材を省略した外観斜視図を示す。このクラッチカバー組立体1は、クラッチオン(動力伝達)時にはエンジンのフライホイールに対してクラッチディスク組立体の摩擦部材を押し付け、またクラッチオフ(動力伝達遮断)時にはその押し付けを解除するための装置である。なお、ここでは、フライホイール及びクラッチディスク組立体は省略している。
クラッチカバー2は、概ね皿形状のプレート部材であり、外周部が例えばボルトによりフライホイールに固定される。クラッチカバー2は、環状のクラッチカバー本体2aと、外周側の円板状部2bと、内周側の平坦部2cと、を有している。円板状部2bは、クラッチカバー本体2aの外周側に形成され、フライホイールの外周部に固定される。平坦部2cは、クラッチカバー本体2aの内周部から半径方向内側へ延びる平坦な部分である。この平坦部2cには、軸方向に貫通する複数の孔2dが形成されている。
プレッシャプレート3は、環状の部材であって、クラッチカバー2のクラッチカバー本体2a内部に配置されている。プレッシャプレート3のフライホイール側(図2において下側)の側面には、クラッチディスク組立体の摩擦部材と摺接する摩擦面が形成されている。また、プレッシャプレート3は、複数のストラッププレート(図示せず)によってクラッチカバー2に連結されており、クラッチカバー2に対して、軸方向には移動可能であるが相対回転不能である。なお、クラッチ連結状態では、ストラッププレートは軸方向にたわんでおり、このストラッププレートのたわみ(復元力)によって、プレッシャプレート3はフライホイールから離れる側に付勢されている。
複数のファルクラムリング4は、それぞれ円弧状の部材、すなわち、環状の部材を円周方向に分割して形成された部材であり、図2及び図3に示すように、軸方向の第1端側4a(フライホイール側)がプレッシャプレート3の環状溝3aに挿入されている。また、ファルクラムリング4の軸方向の第2端側4b(トランスミッション側)は、環状溝3aから突出している。ファルクラムリング4の第1端4aには、図3から明らかなように、円周方向の複数個所において摺動部11が形成されている。この摺動部11は、プレッシャプレート3の環状溝3aの底面に形成された摺動部10の傾斜面に当接しており、円周方向(図3のR1方向)に向かってその高さがより低くなるように傾斜する傾斜面を有している。
ダイヤフラムスプリング5は、プレッシャプレート3とクラッチカバー2との間に配置された円板状部材であり、図4にその一部を示す。このダイヤフラムスプリング5は、環状弾性部5aと、環状弾性部4aの内周部から径方向内側に延びる複数のレバー部5bとから構成されている。環状弾性部5aの外周端はファルクラムリング4の第2端4bに支持されている。また、ダイヤフラムスプリング5のレバー部5b間はスリットになっており、スリットの外周部には小判状の孔5cが形成されている。
摩耗量検出機構6は、図2、図5及び図6に示すように、ファルクラムリング4の外周部の複数個所に配置されている。この摩耗量検出機構6は、クラッチディスク組立体を構成する摩擦部材の摩耗量が所定量に達したことを検出する機構であり、移動検出部材15と、カバー側検出部材16と、第1コイルスプリング17と、板ばね18と、を有している。
摩耗追従機構7は、摩擦部材の摩耗量、すなわち移動検出部材15の移動量に追従させて、ダイヤフラムスプリング5の姿勢を初期の姿勢に保つための機構である。この摩耗追従機構7は、複数のファルクラムリング4に加えて、前述のプレッシャプレート3及びファルクラムリング4のそれぞれに形成された摺動部10,11と、複数の第2コイルスプリング24と、を有している。
クラッチオン(連結)状態では、ダイヤフラムスプリング5の押圧荷重は、ファルクラムリング4を介してプレッシャプレート3に作用し、これによりクラッチディスク組立体の摩擦部材はプレッシャプレート3とフライホイールとの間に挟持されている。このとき、図5及び図6に示すように、移動検出部材15の歯15aはカバー側検出部材16の歯16aに噛み合っている。
(1)摩耗量検出機構6では、移動検出部材15及びカバー側検出部材16の歯15a,16aが常に噛み合っているので、振動によって摩耗量検出結果が変化するのを抑えることができる。このため、摩耗量検出機構6の作動が安定し、正確な摩耗補償を行うことができる。
本発明は以上のような実施形態に限定されるものではなく、本発明の範囲を逸脱することなく種々の変形又は修正が可能である。
