动力传动装置
Abstract:
一种动力传动装置（4），具有：刚体（58；120b；220），所述刚体包括接触部，该接触部与第一或第二摩擦构件接触，并且所述刚体将该接触部从与第一或第二摩擦构件接触的位置移动到不与第一或第二摩擦构件接触的位置；弹性体（54；124；224），该弹性体向所述刚体施加将所述接触部移动到与第一或第二摩擦构件接触的位置；第一推动机构，所述第一推动机构向所述刚体施加将接触部移动到与第一或第二摩擦构件接触的位置的液体压力；以及，第二推动机构，所述第二推动机构向所述刚体施加将接触部移动到与第一和第二摩擦构件不接触的位置。
Abstract(English):

A power transmission device (4) has a rigid body (58; 120b; 220) that includes a contact portion coming into contact with the first or second friction member and that moves the contact portion from a position of contact with the first or second friction member to a position of no contact with the first and second friction members, an elastic body (54; 124; 224) that applies to the rigid body a force moving the contact portion to a position of contact with the first or second friction member, a first pushing mechanism that applies to the rigid body a pressure of liquid moving the contact portion to a position of contact with the first or second friction member, and a second pushing mechanism that applies to the rigid body a pressure of liquid moving the contact portion to a position of no contact with the first and second friction members.
