Abstract:
A synchronizing system for connecting a first rotary body and a second rotary body arranged in a manner spaced from each other and at the same time relatively rotatable about an identical axis, while synchronizing the first rotary body and the second rotary body with each other, so as to transmit torque between the first rotary body and the second rotary body,the synchronizing system comprising: an engagement member which is arranged between the first rotary body and the second rotary body in a manner such that said engagement member is capable of moving along the axis and rotating about the axis relatively with respect to each of the first rotary body and the second rotary body; at least one first friction disc rotating together with the first rotary body; at least one second friction disc each arranged in a manner opposed to and spaced from said at least one first friction disc, said at least one second friction disc rotating together with said engagement member, and being brought into surface contact with said at least one first friction disc when said engagement member is urged toward the first rotary body, thereby synchronizing said engagement member and the first rotary body with each other; a movable member which rotates together with the second rotary body and is capable of moving along the axis with respect to the second rotary body such that said movable member can move to a disconnected position in which said movable member is spaced from said engagement member, a synchronizing position in which said movable member is capable of abutting against said engagement member from an opposite side to the first rotary body, and a connected position in which said movable member is engaged with the first rotary body; and a synchronizing member which, when said movable member moves from the disconnected position to the synchronizing position, is driven by said movable member to thereby urge said engagement member toward the first rotary body, whereby said synchronizing member starts to synchronize the first rotary body and the second rotary body via said at least one first friction disc and said at least one second friction disc and causes said engagement member to abut against said movable member located in the synchronizing position.
