PROBLEM TO BE SOLVED: To provide a clutch mechanism for a vehicle which is small in drag torque at the time of blocking of power, and small in a physique.SOLUTION: A clutch hub 76 is constituted of a clutch hub main body 76b which is non-rotatably connected to a rear-wheel side output shaft 44, and an inner hub 76d which is relatively rotatably arranged at the clutch main body 76b, and with which an internal peripheral side of a friction engagement element is relatively non-rotatably engaged. The clutch hub also comprises a sleeve 77 which is relatively non-rotatably and relatively movably arranged at the inner hub 76d in a rotational axial line C1 of the rear-wheel output shaft 44, and interlocks with a piston 82 up to a position in which the sleeve is engaged with the clutch hub main body 76b. At the time of blocking of power, since a plurality of friction plates 80 do not relatively rotate with respect to one another, drag torque is significantly small. Furthermore, rotational synchronization and an adjustment function of transmission torque can be performed by one piston drive unit PD1, and a physique of a front-wheel drive clutch 50 becomes small.SELECTED DRAWING: Figure 3
【課題】動力遮断時の引き摺りトルクが小さく且つ体格の小さな車両用クラッチ機構を提供する。【解決手段】クラッチハブ76は、後輪側出力軸44に相対回転不能に連結されたクラッチハブ本体76bと、クラッチハブ本体76bに対して相対回転可能に設けられ、前記摩擦係合要素の内周側が相対回転不能に係合させられたインナーハブ76bとから構成され、インナーハブ76dに対して相対回転不能且つ後輪側出力軸44の回転軸線C1方向の相対移動可能に設けられてクラッチハブ本体76bと係合する位置までピストン82に連動するスリーブ77を、備える。動力遮断時には、複数の摩擦板80相互は相対回転しないので引き摺りトルクが大幅に小さい。また、回転同期と伝達トルクの調整機能を1つのピストン駆動装置PD1で行なうことができ、前輪駆動用クラッチ50の体格が小さくなる。【選択図】図3
