    Force transmission components of a double clutch mechanism and double clutch mechanism
    The present invention relates to a set of force transmission members of a double-clutch mechanism as used in the automotive field. The invention also relates to a double clutch mechanism and a transmission system incorporating such a double clutch mechanism.
    Known double-clutch mechanisms are known comprising a first and a second clutch as well as a first and a second actuator making it possible to generate a force for configuring the first and the second clutch respectively in a clutched or disengaged configuration. The force generated at each actuator is transmitted to the corresponding clutch via a force transmission member. Thus, the displacement of the actuator is transmitted to the corresponding force transmission member which, in turn, displaces first friction elements relative to second friction elements of the corresponding clutch in order to configure it in the either of the configurations mentioned.
    In known manner, the force transmission members take the form of a circular corrugated sheet, a first end - generally the radially inner end - is in connection with the corresponding actuator and a second end - generally the radially end external - is in connection with the corresponding clutch. In order to minimize the radial and axial dimensions of the double-clutch mechanism on which they are assembled, the force transmission members of each clutch are mounted coaxial with respect to an axis of rotation of the double-clutch mechanism and have, in the axial direction , numerous similar folds allowing the first force transmission member associated with the first clutch to slide axially without contact with the second force transmission member associated with the second clutch, and vice versa.
    More particularly, in double clutch mechanisms of the radial type, for which the first clutch is located radially outside the second clutch, it is known to fold radially under the second clutch part of each force transmission member in order to reduce the axial size of the dual clutch mechanism. This configuration however requires guaranteeing the free sliding of each force transmission member with respect to the other, without interference between them.
    Thus, in known manner, each force transmission member of such a double radial clutch mechanism is folded radially under the second clutch, in a similar manner to the other force transmission member but according to a different diameter. In other words, the organ of
    -2transmission of force associated with the external clutch is generally folded under the second clutch according to a diameter smaller than that at which the first force transmission member is folded under said second clutch.
    If this configuration makes it possible to avoid any interference between the force transmission members when they are moved axially by the corresponding actuators, it does however have the drawback of increasing the radial size by folding each force transmission member under the second clutch and following two different diameters.
    The object of the present invention is to respond at least in large part to the above problems and to also lead to other advantages by proposing a new set of force transmission members making it possible to reduce the radial size of a mechanism with double clutch on which it would be intended to be assembled.
    According to a first aspect of the invention, at least one of the abovementioned objectives is achieved with a set of first and second force transmission members of a double-clutch mechanism, each force transmission member being respectively intended to transmit an axial force between an actuator of the double clutch mechanism and a first and respectively a second clutch of the double clutch mechanism, each force transmission member being mounted coaxially with respect to a common axis of rotation, characterized in that, the force transmission members are entangled with one another at a zone of in cb to be ent em t.
    According to the first aspect of the invention, the two force transmitting members are entangled with each other at the level of an entanglement zone. By overlapping, it is understood that a part of the first force transmission member can slide axially through a similar part of the second force transmission member without interfering with it, that is to say without coming into contact with she ; and / or that a part of the second force transmitting member can slide axially through an analogous part of the first force transmitting member without interfering with it, that is to say without coming into contact with it.
    This overlapping characteristic must be checked when the two transmission members are placed in a configuration similar to that in which they are intended to be mounted on a double-clutch mechanism, and for a relative axial displacement of one of the transmission members. force with respect to the other at most equal to an axial movement of the actuator with which said force transmission members are intended to collaborate. By way of nonlimiting example, one can check the entanglement characteristic by coaxially mounting the two force transmission members and by separating them by an axial distance - measured at the level of a similar front face of their outer radial end. - between 0 and 10 millimeters and in
    -3 axially displacing the first force transmission member with an axial displacement of between 0 and 6 millimeters.
    The entanglement and / or the corresponding entanglement area of the force transmission members can take various forms which will be described in the following paragraphs and in the figures illustrated below.
    Preferably, but not exclusively, the assembly according to the first aspect of the invention is limited to the force transmission members which do not voluntarily transform, and more particularly by amplification, the actuation force generated at the level of one of their ends by the actuator: the axial force transmitted by each force transmission member at the level of the corresponding clutches is at most equal to the axial force generated by the corresponding actuator. In other words, the assembly according to the first aspect of the invention more specifically addresses so-called passive force transmission members which only provide a conservative effect of the axial actuation force produced by the actuator. corresponding to the elastic deformations near said force transmission members when they are subjected to said actuation forces. In other words again, the assembly according to the first aspect of the invention does not address the force transmission members of the type of a connecting rod or a diaphragm for example, or of those producing an effect analogous to that of a lever between one and the other of their ends and leading to amplify the actuation force produced by the actuators to which they are connected.
