Abstract:
1. Transmission device comprising at least a first rotary member mounted coaxially on a second rotary member, said first rotary member being able to rotate at least in one direction independently from said second rotary member, and in the opposite direction, able to be constrained to said second rotary member to rotate solidly therewith, wherein said transmission device is able to assume a first and a second condition of use, wherein said first rotary member is able to rotate in the two directions independently from said second rotary member, and a third condition of use wherein clamping means, integrally associated with said first rotary member, move from a position of non-interference to a constraint position wherein they constrain said second rotary member to make said first rotary member and said second rotary member rotationally solid, wherein said first rotary member comprises at least two components, respectively a first component and a second component, axially associated with each other, a first of said components including guide means with respect to which said clamping means are able to slide or oscillate to move from said position of non-interference to said constraint position.
