ABSTRACT:
This variator is improved in order to improve reliability and prolong its life.
For this purpose it comprises a friction elements clamping plate provided with two cylindrical skirts which axially extend from opposite sides of the plane of the clamping plate and enable the clamping plate to be supported by the housing by bearings which are axially spaced apart and located on opposite sides of the plane of the clamping plate. Moreover, a ring carrying ramps which adjust the clamping force exerted by the clamping plate in accordance with the torque transmitted is connected to the clamping plate by a relatively deformable connection so that the clamping plate is not subjected to a particularly harmful alternating tipping.
