In the present embodiment, torsion damping mechanism 7 can be integrated in the twin shaft shown in Fig. 1 and keep off machine again
On any one rotatable parts of structure 10, such as, it is preferably integrated in the first gear ring 143 or the first quilt
On brake components 152 etc. are one or more.Such as, it is integrated in the first gear ring when torsion damping mechanism 7
Time on 143, in the first rotatable parts 71 and the second rotatable parts 72 and the first power source
Output shaft 111 and the second power source output shaft 112 are directly connected to, and the first rotatable parts 71 and
Be provided with internal tooth on another in two rotatable parts 72, so with first planet gear train 142
Carry out internal messing.When torsion damping mechanism 7 is integrated on the first braked part 152, first turn
One in dynamic component 71 and the second rotatable parts 72 is directly connected to the first sun gear 141, and
Another in first rotatable parts 71 and the second rotatable parts 72 is carried out by the first brake component 151
Braking.It should be noted that torsion damping mechanism 7 can be integrated in the first gear ring 143 He simultaneously
First braked part 152, is arranged the most respectively on the first gear ring 143 and the first braked part 152
First torsion damping mechanism identical with structure described above and the second torsion damping mechanism.Thus real
Existing two grades of vibration dampings.In the present embodiment, torsion damping mechanism 7 can also be integrated in the first row carrier
144 and second one or many of gear ring the 163, second planet carrier the 164, second braked part 172
On individual, it is achieved in multistage detection.Certainly, the first gear ring 143 and the first braked part 152,
And second gear ring 163 and the second braked part 172 be more highly preferred to.
Equally, torsion damping mechanism 7 can also be integrated in appointing of the twin shaft times retaining device shown in Fig. 2
Anticipate on rotatable parts.
Owing to the rotating speed from electromotor to automotive transmission and torque are periodically continually changing,
This can make the twisting vibration that power train produces；On the other hand owing to running car is at uneven road
On, angular velocity changes suddenly to make automotive transmission occur, also can cause twisting vibration.These reverse
Vibration all can be to Parts for Power Train impacting property load so that it is the lost of life, even part of damage.
This utility model by retaining device again integrated torsional damper mechanism, can eliminate twisting vibration and
Avoid resonance, prevent power train from transshipping, therefore can an individual components the most integrated " times gear "
And the multiple function such as " vibration damping ".
Further, owing to torsion damping mechanism uses double rotatable parts structure and has certain mass,
Therefore by calculating and configure the quality of the two, it is possible to achieve the function identical with double mass flywheel,
And then the most integrated " double mass flywheel " function.
In the above-described embodiments, only this utility model is carried out exemplary description, but this area
Technical staff can be without departing from spirit and scope of the present utility model after reading present patent application
In the case of this utility model is carried out various amendment.
