Definitions
- the invention relates to a torsional vibration damper, in particular for the drive train of a motor vehicle.
- Torsional vibration dampers are widely known in the art.
- dual mass flywheels with two relatively rotatable flywheel masses are known, which are opposite to the restoring force of energy storage rotatable relative to each other, wherein the energy storage are accommodated in a pocket of the flywheels and supported there in the circumferential direction, with the other of the flywheels connected to a flange is, which engages between the force accumulators in the pocket and the force accumulators acted upon in the circumferential direction when the two masses are rotated relative to each other.
- the pocket is formed by one of the flywheel masses and a cover disk, which are welded together radially on the outside.
- a material distortion occurs, whereby the risk of penetration can exist.
- An embodiment of the invention relates to a torsional vibration damper with a first flywheel and a second flywheel, wherein the first flywheel and the second flywheel are opposite to the restoring force of energy storage rotatable relative to each other, wherein one of the flywheel masses forms a pocket for receiving the energy storage and the other flywheel a flange which engages in the pocket between the force accumulators, wherein the force accumulators are supported in the circumferential direction of contact areas of the pocket and also on contact areas of the flange, wherein the pocket is formed by one of the flywheels and a cover plate connected thereto, wherein both the flywheel a first contact area and the cover plate have a second contact area, on which the flywheel is connected to the cover plate, wherein the connection of the contact areas is effected by a snug fit.
- the cover plate has an axially extending second collar, wherein the first abutment portion of the first collar and the second abutment portion of the second collar is formed.
- first collar engages over the second collar radially outward.
- second collar overlaps the first collar radially on the outside.
- first abutment region and the second abutment region each have an encircling annular region extending in the axial direction, against which the abutment regions contact. This can be advantageously produced by deep drawing, which allows a simple way of production.
- first collar or the second collar has a recess in the region of the abutment region in which the seal is arranged. Thereby, a defined space is created, in which the seal is to be arranged, whereby a simple and defined mounting of the seal is achieved.
- one of the collars is supported on an energy storage stop or on an energy storage channel in the axial direction. This ensures that the elements are defined can be applied to each other.
- the energy accumulator is a bow spring.
- a long swing angle of the flywheels can be achieved relative to each other, which is advantageous for the vibration damping.
- the flywheel and / or the cover plate are formed as sheet metal parts is particularly advantageous. This advantageously ensures that the elements are easily manufactured and can be reshaped to form the pocket for receiving the energy storage.
- the flywheel and / or the cover plate can optionally be produced as turned parts, for example, cast material.
- Fig. 1 is a schematic representation of a detail of a torsional vibration damper.
- the torsional vibration damper 1 shows a torsional vibration damper 1 with a first flywheel 2 and a second flywheel 3.
- the torsional vibration damper 1 is for example a dual mass flywheel, a vibration damper a clutch disc, a torque converter or other damper in particular in the drive train of a motor vehicle.
- the flywheel is designed as a sheet metal part.
- the first flywheel 2 and the second flywheel 3 are arranged opposite to the restoring force of force accumulators 4 rotatable relative to each other, in particular as rotatably mounted relative to each other.
- the energy storage can be advantageously formed in one embodiment as a bow springs.
- the energy storage 4 are received in a pocket 5.
- the pocket 5 is formed by one of the flywheel masses 2, 3.
- the other of the flywheel masses 3, 2 a flange 6, which engages in the pocket 5 between the force accumulator 4, which are arranged in the pocket 5 in the circumferential direction relative to each other.
- the force accumulators 4 are arranged in the circumferential direction in the pocket 5, wherein the force accumulators are supported on contact areas 7 of the pocket 5 and on contact areas 8 of the flanges 6.
- the pocket 5 is formed by one of the flywheels 2 and a cover sheet 9 connected thereto.
- both the flywheel 2 a first contact area 10 and the cover plate 9 a second contact area 1 1, at which the flywheel 2 with the Cover plate 9 is connected.
- the connection of the contact areas 10, 1 1 is achieved by a fit 16 of the two parts.
- the cover plate 9 is formed as a sheet metal part.
- the flywheel 2 has a first collar 12 extending in the axial direction, and also the cover plate 9 has a second collar 13 extending in the axial direction.
- the first contact area 10 is formed by the first collar 12 and the second contact area 11 of the second collar 13.
- first collar 12 engages over the second collar 13 radially outward.
- second collar 13 may overlap the first collar 12 radially on the outside.
- first contact area 10 and the second contact area 1 1 are formed such that they each have a extending in the axial direction circumferential annular area, to which the contact areas 10, 1 1 touch. As a result, it can be effected that the interior of the pocket is sealed by touching the ring areas.
- a seal 14 is arranged between the first collar 12 and the second collar 13, .
- the second collar 13 may also have a recess 15 in the region of the abutment region 11 in which the seal 14 can be arranged.
