Title:
スプラインなしの回転制御装置
Document Type and Number:
Japanese Patent JP3881519
Kind Code:
B2
Abstract:
A rotational control apparatus (10, 10a) for controlling the transmission of rotational forces between first and second relatively rotatable members (26, 120, 120a) includes a piston (76, 76a) interconnected for concurrent axial movement with the second member through a bearing unit (146) which enables relative rotation and concurrent axial shifting of the piston (76, 76a) and the second member (120, 120a). The piston (76, 76a) is only interconnected t o the first member (26) through the use of one or more springs (116) such that at least partial relative rotation between the piston (76, 76a) and the firs t member (26) is accomodated. The piston (76, 76a) includes one axial side surface (80) that defines an enlarged area to be acted upon by a source of pressurized fluid introduced into a chamber (92) to cause the piston (76, 76 a) and the second member (120, 120a) to simultaneously shift against the biasin g force of the springs (116) in order to control the selective engagement/disengagement between the first rotatable member (26) and the second member (120, 120a).
