As for transmission input shaft), relative to an axle journal (input block of such as double clutch), relatively
In a torque converter or similar power unit or rotate sealed relative to analog formation.
Described disc-shaped part is the most differently hardened.Such as, in order to set the hard of interior teeth portion
Degree, whole disc-shaped part by thermmohardening, such as, is annealed.
The arm of the mechanically strong load of described disc-shaped part can be hardened additionally by sensing.
Described disc-shaped part can be such as made into by punching press and forming method by sheet material upon hardening.Should
Disc-shaped part is except the broaching of interior teeth portionOutside can be without cutter ground (werkzeugfallend)
Manufacture.
The method being used for manufacturing proposed torsional vibration damper of this suggestion includes: had by sheet material manufacture
The punching press of the disc-shaped part of one axial protruding head being arranged on inner radial and plate forming technique and hard
Metallization processes, wherein, makes described disc-shaped part harden in the first cure step, such as anneal, and,
The arm of described disc-shaped part is made to be hardened by sensing in the second cure step.Additionally, the method is also
Including Broaching Technology, described interior teeth portion of broaching out in this Broaching Technology.The broaching of described interior teeth portion is excellent
Selection of land is implemented after the first cure step and before the second cure step.Below will be by only
The embodiment present invention explained in detail shown in one accompanying drawing.This torsional oscillation illustrated according to the present invention subtracts
Shake the partial cross section of device.
Accompanying drawing explanation
Unique accompanying drawing illustrates the torsional vibration damper 1 can arrange in the way of reversing around rotation axis d
Top.
Detailed description of the invention
Unique accompanying drawing illustrates the torsional vibration damper 1 can arrange in the way of reversing around rotation axis d
Top.Input block 2 and output block 3 are configured to resist the limited efficacy of spring assembly 4
Ground relative torsion.Output block 3 is by having the flange components 5 of radial expansion arm 6 and having interior teeth portion 8
Boss assembly 7 constitute.Flange components 5 and boss assembly 7 integrally constitute disk shaped part 9.
Input block 2 includes two in radially outer phase in the case of constituting a primary flywheel mass
Compact siro spinning technology, the disk shaped part 11,12 such as welded and flywheel ring gear 13 mutually.Disk shaped part 11 is borrowed
Help screw 14 to be received on a unshowned bent axle and opened by a break-through of disk shaped part 9
Mouth 15 screws with this bent axle.
Disk shaped part 11,12 form doughnut 16, receive the arch of spring assembly 4 in this doughnut
Spring 17.Load for loading the input side of semielliptic spring 17 in circumferential direction in semielliptic spring side
Device realizes by disk shaped part 11, the sightless imprinting moulding portion of 12.Semielliptic spring 17
Outlet side loads and realizes by the arm 6 being coupled in doughnut 16 by inner radial.Doughnut 16
To inner radial at disc-shaped part 9 and disc-shaped part 11, by by disc spring 19 in the axial direction between 12
The sealing member 18 compressed is sealed in the case of constituting rubbing device.
The riveting between flange components 5 and boss assembly 7 is eliminated by disc-shaped part 9 one-piece construction
Connect.Axially mounted space needed for thus can saving by rivet.Additionally, make single disc-shaped part 9
The assembling of stock control and this torsional vibration damper 1 simplifies.It addition, material can be saved, because eliminating
The stampings that the punching press of flange components 5 removes.
In the case, disc-shaped part 9 adapts in different geometric areas or functional area not
Same hardness requirement.On the one hand the predetermined hardness for forming interior teeth portion 8 is set, on the other hand
The hardness of setting arm 6 unlike this.Manufacture disc-shaped part 9 by punching press and forming method and require plate
The raw-material hardness of material is little.Therefore, by punching press and forming method manufacture, there is axle in the first step
Blank to the disc-shaped part 9 of protruding head 10.Then, this blank is by thermmohardening, such as anneal.Connect again
, axial protruding head 10 is broached out interior teeth portion by Broaching Technology.Finally, arm 6 is at disc-shaped part
The radially outer of 9 is the most preferably arranged with inducing method has bigger hardness.
