Abstract
【解決手段】プレッシャ部材5が非作動位置にあるとき、出力シャフト3を介して第1クラッチ部材4aに回転力が入力されると、第2クラッチ部材4bを移動させて駆動側クラッチ板6と被動側クラッチ板7とを圧接させ得るバックトルク伝達用カムとを有するとともに、バックトルク伝達用カムは、連動部材9に対して近接する方向に第2クラッチ部材4bを移動させて当該連動部材9とウェイト部材8との当接を保持し得るものである。
【選択図】図2
Description
本実施形態に係る動力伝達装置は、二輪車等の車両に配設されて任意にエンジンの駆動力をミッションや駆動輪側へ伝達し又は遮断するためのもので、図1〜19に示すように、車両のエンジンの駆動力で回転する入力ギア1(入力部材)が形成されたクラッチハウジング2と、クラッチ部材(第1クラッチ部材4a及び第2クラッチ部材4b)と、クラッチ部材(第1クラッチ部材4a及び第2クラッチ部材4b)の図2中右側に取り付けられたプレッシャ部材5と、複数の駆動側クラッチ板6及び複数の被動側クラッチ板7と、クラッチハウジング2内を径方向に移動(転動)可能な鋼球部材から成るウェイト部材8と、連動部材9と、手動操作又はアクチュエータ(不図示)により作動可能な作動部材10とから主に構成されている。なお、図中符号Sは、スプリングダンパを示しているとともに、符号B1はローラベアリング、及び符号B2、B3はスラストベアリングをそれぞれ示している。
エンジンが停止又はアイドリング状態のとき、入力ギア1にエンジンの駆動力が伝達されない或いは入力ギア1の回転数が低回転であるため、図2に示すように、ウェイト部材8が内径側位置とされるとともに、プレッシャ部材5が非作動位置とされている。このとき、出力シャフト3(出力部材)を介して第1クラッチ部材4aに回転力が入力されると、図22に示すように、バックトルク伝達用カムの作用によって、第2クラッチ部材4bが同図中右側に移動し、駆動側クラッチ板6及び被動側クラッチ板7が圧接されてエンジン側に回転力を伝達させる。
