Definitions

  • the invention relates to a dual-mass flywheel with a primary mass and a secondary mass, which are rotatably mounted to one another on a common axis and interact with one another via a spring-damper arrangement. Furthermore, the invention relates to a method for assembling such a dual mass flywheel.
  • Such dual-mass flywheels are sufficiently known from the prior art and are found in particular in flywheels of motor vehicles, which in turn interact with a friction disk and a clutch pressure plate of a vehicle clutch.
  • the flywheel is designed as a dual-mass flywheel in order to particularly effectively dampen vibrations that can be found in such a drive train.
  • the invention proposes, on the one hand, a dual-mass flywheel with a primary mass and a secondary mass, which are rotatably mounted to one another on a common axis and via a spring Damper arrangement interact with each other, which is characterized in that the two masses are positioned axially to one another via a clip connection.
  • the invention proposes as a solution a method for assembling a dual-mass flywheel with a primary mass and a secondary mass, which are rotatably mounted on a common axis and interact with one another via a spring-damper arrangement, which is characterized in that first a first of the two masses connected to a drive shaft or an output shaft and then the second of the two masses is plugged onto the first of the two masses.
  • the two masses can be easily positioned axially to one another during or after being attached, so that the two partial masses are then connected to form a structural unit and the dual-mass flywheel is fully assembled.
  • axial positioning means an arrangement of the two masses in the axial direction relative to one another such that they cannot be separated from one another in the axial direction without overcoming a potential mountain, for example without opening the clip connection.
  • the axial forces in particular also the forces which tend to separate the primary mass and the secondary mass from one another in the axial direction, are relatively low.
  • a plug connection may already be sufficient to connect the two masses with one another to a sufficient extent.
  • a clip connection is advantageously provided so that the two masses are positioned axially to one another. This can in particular facilitate subsequent assembly or further processing of the drive train comprising the dual-mass flywheel according to the invention.
  • a clip connection also has the advantage that, with suitable dimensions, they can subsequently be opened again easily can, so that disassembly for repair purposes is greatly simplified by the present invention.
  • the primary mass is first mounted on a drive shaft and then the secondary mass is clipped on, since a drive shaft is usually subjected to relatively large vibrations and stresses, so that a sufficiently firm connection must be guaranteed between the primary mass and the drive shaft ,
  • the secondary mass can then be removed for disassembly, so that the corresponding screw connections or other stable connections can also be achieved retrospectively without any problems, possibly even with heavy tools.
  • the primary mass preferably comprises at least one assembly which is positioned axially with respect to the secondary mass and is fixed in terms of rotation, but is axially displaceable with respect to the remaining primary mass when the two masses are separated or when the clip connection is released.
  • Such an assembly makes it easier to put the two masses on top of one another and to position the rotary bearings well about the common axis before plugging them on, so that after assembly an operationally reliable transmission of the torque from the primary mass to the secondary mass and vice versa is ensured.
  • the secondary mass can comprise at least one assembly which is positioned axially with respect to the primary mass and non-rotatably, but is axially displaceable with respect to the remaining secondary mass when the two masses are separated or when the clip connection is released.
  • clip connection is understood to mean any latching connection between the two masses, which can be produced by overcoming a certain assembly force and which positions the two masses axially relative to one another.
  • the assembly force generally overcomes the spring force of small latching elements
  • Such a clip connection can preferably be opened again non-destructively under a dismantling force by counteracting the spring force of these latching elements in a suitable manner.
  • FIG. 1 shows a first dual mass flywheel according to the invention in a radial section
  • Figure 2 shows the dual mass flywheel according to Figure 1 in another radial section; and Figure 3 shows a second dual-mass flywheel according to the invention in a similar representation as Figure 2, in its assembled state with respect to a clutch in a clutch chamber.
  • the dual-mass flywheel 101 shown in FIGS. 1 and 2 comprises a primary mass 103 and a secondary mass 105.
  • the primary mass 103 comprises a primary plate 107 and a centering hub 109 and a screw plate 111.
  • the primary plate 107 also carries a starter ring gear 113.
  • the secondary mass 105 essentially comprises a secondary plate 115, which is mounted on the centering flange 109 via a slide bearing 117.
  • This spring-damper arrangement 119 comprises a spring part 121 and a friction part 123. It goes without saying that the spring part 121 may not only act as a spring, but also as a friction and therefore damping or energy-wiping, while the friction part 123 also within certain limits also spring Can have properties.
  • assemblies are provided on the primary and secondary sides, respectively, which create an operative connection from the respective mass 103 and 105 to the spring-damper arrangement 119 or to the spring part 121 and to the damper part 123 ,
  • this is a primary spring washer 125 with respect to the spring part 121, which surrounds springs 127 of the spring part 121 and which is positioned on the central flange 109 in a rotationally fixed manner with respect to the primary mass 103 via a positive connection 131 that is effective in the direction of rotation about the axis of rotation 129 of the dual-mass flywheel 101.
  • the secondary mass 105 has a double sheet 133, which is positioned on the secondary plate 115 via a rivet connection 135 and also engages around the springs 127.
  • the spring part 121 also comprises a double free spring plate 137, which serves to position the springs 127.
  • the damper part 123 comprises two pressure plates 139 on the primary side, which are axially clamped towards one another via a plate spring 141 and between which two wedges 143 and 145 are arranged, which are pressed against one another by the plate spring 141 and preferably have varying thicknesses in the circumferential direction.
  • One of the wedges 143, 145 namely the radially inner wedge 145, is in rotary connection with the double sheet 133 of the secondary mass 105, the wedge 145 having stops in the circumferential direction, against which the double sheet 133 strikes at certain angles of rotation.
  • a clip connection 147 is provided between the secondary plate 115 and the central flange 109, which axially positions the secondary mass with respect to the primary mass.
  • the clip connection comprises an assembly 149 of the central flange 109, a groove 151 in the secondary plate 115 and a plastic ring 153 which is arranged in the groove 151 and is encompassed by a nose of the assembly 149.
  • the clip connection positions the two masses 103 and 105 against axial forces which move these two away from one another. It is immediately apparent that the clip connection 147 can be opened radially inward by sufficiently large axial forces or by bending the assemblies 149.
  • the primary-side spring plate 125 and the secondary-side double plate 131 can be axially removed from the primary mass 103 together with the secondary plate 115, since both the connection 131 and the openings between the wedges 145 do not prevent the modules 125 and 133 from to be axially removed from them.
  • these assemblies are axially fixed with respect to the secondary plate 115 via the rivets 135 and the free spring plate 137.
  • the central flange 109 or another assembly connected to the primary mass 103 preferably has a stop 155 which ensures that the primary-side spring plate 125 extends in the axial direction. is positioned sufficiently precisely so that the slide bearing 117 and the secondary plate 115 are also positioned axially with sufficient accuracy. Depending on the specific configuration, further corresponding stops can also be provided.
  • FIG. 3 differs only slightly from the arrangement according to FIGS. 1 and 2, so that a detailed description of this arrangement is dispensed with.
  • the same digits have been used for modules with the same effect, these comprising the digits 2 instead of the digit 1 in their first position.
  • the main difference between the two embodiments is that the embodiment according to FIGS. 1 and 2 has a chamfered nose on the assembly 149, while this nose on the assembly 249 is rectangular on the outside.
  • FIG. 3 shows a possible installation of a torsional vibration damper according to the invention, in which the secondary plate 215 is connected via rivets 257 to a clutch housing, which in turn carries a clutch pressure plate 249 with a plate spring 261, which presses the clutch pressure plate 249 against a friction disk 263, which between the clutch pressure plate 249 and the secondary plate 215 is clamped.
  • the overall arrangement is arranged in a clutch space 267. If the radially inner end of the plate spring 261 is loaded, the friction disk 263 is relieved and the corresponding clutch is thus opened.
