Abstract:
A contact pressure system for a continuously variable transmission, said system comprising: at least one torque sensor having an input side that is loaded with a torque from a power source and having an output side that provides a contact pressure force that acts on an axially-movable disk and that depends on the torque applied on the input side, wherein the contact pressure system includes at least one transfer unit positioned between the power source and the torque sensor and that transfers torque between the power source and the torque sensor, a first component of the torque sensor that is connected into the flow of power when a torque is applied to the torque sensor in a first direction, and a second component of the torque sensor that is switched into the flow of force when a torque acts on the torque sensor in a second direction opposite to the first direction.
