Definitions
- the invention relates to a torsion damping device mounted between two coaxial rotating parts, for transmitting a torque between these two parts with vibration damping and torque oscillation, and is particularly applicable to friction clutches for motor vehicles.
- a torsion damper comprises two guide washers which are coaxial with the two rotating parts and which are rotatably connected to each other and to one of the rotating parts, an annular web disposed between the two guide washers and means connecting in rotation of this annular web to the other rotating part.
- Elastic circumferential members such as helical springs, are mounted in corresponding windows of the web and guide washers and are supported at their ends on the radial edges of these windows to transmit a torque between the washers. guide and the annular web while absorbing by elastic deformation the vibrations and the oscillations of torque.
- the axes of these springs are in the plane of the annular web so that, during an angular movement between the guide washers and the annular web, one end of each spring is in axial support on a radial edge of a window of the annular web and its other end is supported on radial edges of the windows of the guide washers, substantially symmetrical with respect to the plane of the annular web, the result of the support forces of this other end of a spring being axial relative to the spring.
- the springs work in axial compression, which is favorable to their service life.
- each spring is supported by one end on a radial edge of a window of a washer and by its other end on a radial edge of a window of the other washer, but these supports are offset relative to the axis of the spring so that the compression forces of the springs are no longer axial, but oriented diagonally and the compression of the springs is accompanied by a bending which tends to offset them.
- it is necessary to provide means for guiding the springs which create friction liable to disturb the operation of the torsion damper. It is also necessary to oversize the springs so that they support the additional stresses caused by their diagonal compression.
- the present invention aims in particular to overcome these drawbacks of the known technique, without increasing the number of parts, the axial size and the cost of a torsion damper of the aforementioned type.
- a torsional damping device mounted between two coaxial rotating parts for transmitting a torque from one part to another with damping of vibrations and torque oscillations, comprising: two washers coaxial with two rotating parts, - rotational connection means between the two rotating parts and the washers, elastic members with circumferential action mounted between the washers in housings which are formed in these washers and which include means for supporting the ends of the elastic members, characterized in that the two washers are movable in rotation with respect to each other and with respect to the two rotating parts with a limited angular movement and are subjected to rotation by the above-mentioned elastic members in opposite directions tending to bring them into abutment on their connecting means to both of the rotating parts.
- each washer can rotate relative to the two rotating parts and relative to the other washer, independently of this other washer. This therefore makes it possible to associate a first washer with a first rotating part and the second washer with the second rotating part for a direction of rotation and conversely the first washer with the second rotating part and the second washer with the first rotating part for the other sense of rotation and therefore to distinguish one from the other the two directions of rotation.
- Each washer acts in one direction on the elastic members and each elastic member is in constant support by one end on an element of a washer and by its opposite end on an element of the other washer. This results in better support and better maintenance of the elastic members, a reduction in their wear and an increase in their service life.
- the mounting of the device according to the invention is also simpler than in the known technique, none of the washers being integral in rotation with a rotating part, which avoids the crimping operations or the like used in the known technique. As a corollary, the renovation and maintenance of the clutch are also simplified.
- the two washers are identical.
- each washer is in abutment on a means of connection of this washer to one of the rotating parts, and there is a circumferential clearance between this washer and its means of connection to the other rotating part.
- the two washers are formed by stamping or molding with the housings of the above-mentioned elastic members, each housing comprising at one of its ends an axial bearing face of an elastic member placed in said housing.
- the opposite end of the housing is devoid of means for axially supporting the elastic member.
- the housings are formed in said washers by recesses which are located face to face from one washer to the other, each recess being connected by one end to a boss projecting towards the other washer to form the face of axial support of a said elastic member.
- said washers are flat and the housings of the elastic members are formed by windows of the washers, each window having a radial side which serves as an axial support for an elastic member and which comprises means centering and retaining this organ.
- each washer comprises a toothing meshing with a predetermined circumferential play with a toothing of one of the above-mentioned rotating parts.
- the teeth of the washers are formed on their internal periphery and the teeth of the above-mentioned rotating part are formed for example on the external peripheral surface of a cylindrical bearing surface of said rotating part.
- the means for rotationally connecting the washers to the other of the rotating parts comprise, for example, fingers integral with this rotating part and engaged in circumferential slots of limited angular extent of said washers.
- At least one lumen of a washer is positioned relative to a lumen of the other washer so that these two lumens are traversed by the same finger secured to the aforementioned rotating part.
- the means for connecting the washers to the other rotating part comprise lugs integral with the washers and engaged between stops carried by this rotating part, said lugs being substantially radial.
- this torsion damping device forms a unitary assembly, the two washers being hooked to each other by means of circumferential lugs which are offset axially ent to engage one in the others and oppose an axial separation of the washers.
- This unitary assembly can therefore be pre-assembled, then mounted on the rotating parts.
- the device according to the invention can be used for absorbing and damping vibrations and torque oscillations between two rotating parts of any type. It can also be used as a main damper and / or as a pre-damper in a torsional damper of a friction clutch for a motor vehicle.
- pre-damper mounted in series with a main damper in a clutch
- it can be mounted either inside the main damper or outside of it, with a very small axial size.

- the device according to the invention intended to dampen the oscillations and irregularities of the torque between these two rotating parts, comprises two identical washers 16, 18 mounted face to face on the rotating part 10 and each having a toothing at their internal periphery, the teeth 20 of which mesh with the teeth 12 of the first part 10 with a predetermined circumferential play.
- the washers 16, 18 have been shown in partial cutaway to facilitate understanding, but it should be understood that they each extend continuously over 360 ° around the axis of rotation.
- the washers 16, 18 comprise circumferential slots 22 of small angular extent, the slots 22 of one washer being intended to be positioned relative to the slots 22 of the other washer to be traversed by the same cylindrical fingers 14 integral with the another rotating part.
- the washers 16, 18 also include recesses forming substantially semi-cylindrical housings 24 with circumferential orientation, intended to receive elastically deformable members such as helical springs 26 whose length corresponds substantially to that of the housings 24.
- Each housing 24 opens out, at one end, in a boss 28 which projects from the washer in the direction of the opposite washer and which has a substantially semi-circular or U-shaped outline, the opening of which is oriented radially outwards.
- the i-cylindrical housing 24 ends substantially in the middle of the boss 28 and has an end face 30 which is substantially planar and perpendicular to the plane of the washer and which connects the peripheral wall of the housing 24 to the bottom wall of the boss 28 by forming an axial bearing face of one end of the elastic member 26 housed in this housing 24.
- the other end 32 of the housing 24 has, perpendicular to the plane of the washer, a dimension less than half the transverse dimension of the elastic member 26.
- an elastic member 26 placed between the washers in two opposite housings 24, will bear axially at one end on the end face 30 of a housing 24 of a washer and at its other end on the end face 30 of the housing 24 of the other washer.
- the slots 22 of the washers 16, 18 are arranged with respect to the housings 24 and to the cylindrical fingers 14 integral in rotation with the other driving part, so that, when the two washers are mounted on the part 10 one by face of the other as shown in Figure 1 and that the elastic members 26 are inside the housings 24, these members 26 bias the two washers in rotation in opposite directions and tend to bring the ends of the lights 22 into abutment on the cylindrical fingers 14, in the direction indicated by the arrow 34 in FIG. 1 for the washer 18 and in the direction indicated by the arrow 36 for the washer 16.
- the teeth 20 of the washer 18 are stressed on the sides 12a of the teeth 12 of the first rotating part 10 and the teeth 20 of the other washer 16 are biased on the opposite sides 12b of these teeth 20.
- the washer 16 cannot rotate relative to the two rotating parts only in the direction of arrow 34 and the washer 18 can rotate relative to these two parts only in the direction of arrow 36.

- the washer 18 In operation, when a vibration or an irregularity in torque results in a relative rotation of the first rotating part with respect to the other in the direction of the arrow 34, the washer 18 is kept stationary in rotation with respect to 1 ' another rotating part of the f it that the cylindrical fingers 14 integral with this other rotating part are supported on the bottom of the openings 22 of the washer 18 and prohibit its rotation in the direction of the arrow 34, and the other washer 16 is moved in rotation in the direction of arrow 34 relative to the other rotating part by the teeth 12 of the first part 10 which are supported, in this direction of rotation, on the teeth 20 of the washer 16.
- the washer 16 rotates therefore with respect to the other rotating part until the bottoms of the openings 22 of the washer 16 abut on the cylindrical fingers 14 and / or that the teeth 20 of the washer 16 abut on the sides 12a of the teeth 12 of the first part 10.
- This rotation results in an axial compression of the elastic members 26 in the cavities 24 of the washers 16, 18.
- the first part 10 tends to rotate relative to the other part in the direction indicated by the arrow 36, it rotates the washer 18 with it, which has the effect of axially compressing the elastic members 26 in the direction of the arrow 36, the washer 16 being immobilized in rotation on the other rotating part.
- the vibrations and torque irregularities between the two rotating parts are therefore absorbed by the axial compression, in one direction and in the other, of the elastic members 26 housed in the cavities 24.
- the washers rotate with respect to the rotating parts, up to the limit of the angular clearance authorized elsewhere between the two rotating parts, which makes it possible to avoid, if necessary, contacts and impacts between the bases of the lights 22 and the fingers 14 and / or between the teeth 20 of the washer and the sides of the teeth 12, and which also makes it possible to transmit a torque from one rotating part to the other by means limiting their relative angular movement and not through the washers and their rotational connections to the rotating parts.
- the washers 16 and 18 comprise at their external periphery, means for hooking to one another, such as circumferential lugs 38 which are axially offset with respect to the washers, so as to be able to engage one in the others when the washers are face to face and thus prevent the washers from separating axially.
- the axial position of the set of washers 16, 18 on the first rotating part 10 is defined for example by means of a split elastic ring 40 or "circlips" which is engaged in an annular groove formed in the external peripheral toothing of the first rotating part 10.
