  • the first surface 3 or the second surface 4 comprises at least one braking surface 11 carried by at least one first braking arm 30 subjected to the action of at least one first elastic return means 13.
  • This first return means elastic 13 is preferably integral with the shaft 2 or the wheel 5, and is arranged to exert a radial force by relative to the pivot axis D on the second surface 4 or respectively the first surface 3.
  • the first elastic return means 13 is advantageously a flexible blade, more flexible than the shoe 12, which is cantilevered at a distal end of this blade, in the manner of a hammer head on its handle, the end of the flexible blade opposite the shoe being embedded in the corresponding structure, here the structure of the wheel 5 in the cases illustrated by the Figures 1 to 4 .
  • this assembly 1 comprises intrinsic adjustment means 14 by discrete values of the friction exerted by the braking surface 11 on the second surface 4, or respectively the first surface 3.
  • the first surface 3 or respectively the second surface 4 comprises, distinct from one another, on the one hand at least one guide surface 10 according to a predetermined clearance J, about a pivot axis D, of the second surface 4 or respectively the first surface 3, and secondly at least one such braking surface 11, that comprises at least one shoe 12, at the distal end of a first arm 30, subjected to the action of at least less than a first elastic return means 13.
  • This first elastic return means 13 is preferably integral with the shaft 2 or the wheel 5, and is arranged to exert a radial force with respect to the pivot axis D on the second surface 4 or the first surface 3.
  • these intrinsic adjustment means 14 comprise at least one bearing surface 18, which is arranged to cooperate in thrust support with a complementary bearing surface 17 that the shoe 12 has on the side opposite to the braking surface 11.
  • the Figures 1 to 3 show in particular intrinsic adjustment means 14 which comprise at least one second flexible arm 19 carrying such a bearing surface 18.
  • This second arm 19 is, or as on the figure 3 radially limited relative to the pivot axis D opposite it in abutment against an adjusting device 20 arranged to occupy one of a plurality of discrete positions relative to the shaft 2 (or respectively to wheel 5), or as on the Figures 1 and 2 recalled to the complementary bearing surface 17 of the shoe 12 by a second elastic return means 16.
  • the Figures 1 and 2 illustrate a movable braking assembly 1 where the second arm 19 is biased towards the complementary bearing surface 17 of the shoe 12 by the second elastic return means 16.
  • This second arm 19 comprises at least one finger 15 (or respectively a notch), subjected to the return action of the second resilient return means 16 and arranged to cooperate with only one of a plurality of notches 23 that includes the shaft 2 or respectively the wheel 5, in this case the wheel 5 in the case of the figures, each said notch 23 corresponding to a different friction setting value.
  • the Figures 1 and 2 show a series of notches 23 similar to a comb or a toothing, arranged to maintain the position of the finger 5 after its operation.
  • the second elastic return means 16 is advantageously a flexible blade, more flexible than the finger 15, which is cantilevered at a distal end of this blade, in the manner of a hammer head on its handle, the end of the flexible blade opposite the finger being embedded in the corresponding structure, here the structure of the wheel 5 in the cases illustrated by the figures.
  • the shoe 12 is subjected to both the action of at least one first elastic return means 13 and to the action of the second elastic return means 16.
  • the second elastic return means 16 may constitute a simple limit stop for the shoe 12, whose complementary bearing surface 17 then comes into simple support on the bearing surface 18 of the second arm 19, as visible on the figure 1 in this case, the second elastic return means 18 serves essentially to adjust the friction, allowing movement of the finger 15 and placing it in cooperation with a notch 23 selected for a particular value of friction.
  • the figure 2 shows that the second elastic return means 16 can also be used to make its own contribution to the friction, by the exercise of a radial centripetal force F on the shoe 12.
  • the torque exerted on the shoe 12 by the first elastic return means 13 is greater than that exerted by the second elastic return means 16.
  • the second elastic return means 16 is integral with the shaft 2 or respectively the wheel 5, here the wheel 5 in the case of the figures.
  • the second arm 19 is limited radially with respect to the pivot axis D, opposite it, in abutment abutment on an adjusting device 20, which comprises an eccentric adjustment by discrete positions, by example by the use of an eccentric 21 pivoting on the wheel 5, on which it can be stopped in different angular positions, by a notch or the like.
  • the forms of the elastic return means, hooves, arms, and notches, can be very diverse.
  • the figure 4 thus illustrates a third embodiment, with a plurality of curved arms and blades substantially concentric with the shaft 2.
  • the figure 5 illustrates a fourth embodiment, with two arms 30, which are not cantilevered like those of Figures 1 to 4 , but stretched on the serge of the wheel 5 between attachment points 51, 52, 53, 54, and pinching together the shaft 2, each of these arms 30 being subjected to a centripetal radial thrust force exerted by second elastic return means 16 incorporated in the wheel 5.
  • the shaft 2 is then guided by two braking surfaces 11, and there is no area reserved for guiding, as the guide surfaces 4 of the other embodiments.
  • the arrangement of the intrinsic adjustment means 14 is similar to that of the other embodiments presented above. Naturally this variant can be declined with a number of upper arms.
  • the assembly 1 may comprise a plurality of braking surfaces 11, in particular distributed in a balanced manner about the pivot axis D.
  • the wheel 5 is made of monocrystalline or polycrystalline silicon, or a similar material implemented by a photolithographic process, or "MEMS" or “LIGA”, or the like.
  • the shaft 2 is made of ruby.
  • the movable braking assembly 1 consists solely of two components which are the shaft 2 and the wheel 5. And this shaft 2 and this wheel 5 are each a one-piece component comprising all the surfaces of necessary support, as well as the means of recall and maintenance required.
  • the shaft 2 is fixedly mounted on a plate or a bridge that comprises a mechanism 100 or a clockwork movement in which is integrated the movable braking assembly 1 considered.
  • the invention also relates to a clockwork mechanism 100, in particular a movement, comprising at least one such movable braking assembly 1.
  • the invention also relates to a timepiece 200 comprising at least one such movable braking assembly 1.
  • the setting of the brake arming makes it possible to modify the frictional force (or torque) exerted on the shaft, in a reproducible manner, which facilitates and speeds up the adjustments.
  • the invention makes it possible to reduce the number of components compared to a traditional mechanism, in order to reduce the gear sets (still visible on the display at the level of the needles), which goes in the direction of improved reliability, and a reduction in costs, especially since a manufacturing by cutting is possible.
  • the invention reduces wear compared to traditional spring brakes.
