Three-dimensional karussel for a horological movement

A three-dimensional karussel for a horological movement comprising a drive device provided with a barrel and a gear train, said three-dimensional karussel including an inertial mass, an elastic return device for the inertial mass and an escapement mechanism, wherein the horological movement comprises an inner carriage and an outer carriage, the inner carriage carrying the inertial mass, the elastic return device for the inertial mass and the escapement mechanism, the inner carriage being capable of moving in rotation about a first axis of rotation, the outer carriage being capable of moving in rotation about a second axis of rotation, the inner carriage being housed inside the outer carriage, the drive device being configured to actuate the rotational motion of the outer carriage in parallel with the rotational motion of the inner carriage, a first part of the torque provided by the drive device being transmitted to the outer carriage, and a second part of the torque being transmitted to the inner carriage, the drive device being further configured to actuate the escapement mechanism in parallel with the rotational motion of the outer carriage and in parallel with the rotational motion of the inner carriage, with a third part of the torque provided by the drive device being transmitted to the escapement mechanism.
