By between input shaft 310 and S. A. 110 and 210 bearing 315B and 325B being set, the centnifugal force that is produced by rotor 130 and 230 rotations and the weight of rotor 130 and 230 act on input shaft 310 as external force.Increase with the rotating speed of rotor 130 and 230 and proportional change is big from the external force of rotor 130 and 230.If increase the diameter of input shaft 310 in order to ensure the intensity of input shaft 310, the external diameter of planetary wheel and/or rotation sensor also will become big and become the factor that increases actuating device 1 size.Yet restrict rotor 130 and 230 rotating speed can cause power to descend.
Adopt output greater than mainly based on the rotating machine of the output of the rotating machine 100 of the propulsive effort generating of driving engine rotating machine 200 as the propulsive effort that produces powered vehicle.Therefore, the rotating machine 200 that is adopted (for example, when diameter is identical as shown in figure 11, has long axial length (L2＞L1)) than rotating machine 100 is big.The vibration that this means rotating machine 200 the vibration of tending to become greater than rotating machine 100.Therefore, reducing the external force that acts on the input shaft 310 from rotor 230 is particular importance.
Consider above-mentioned situation, in the present embodiment, the external force that acts on the input shaft 310 from S. A. 210 reduces by via bearing 210B1 and 210B2 S. A. 210 directly being bearing on the housing 12.Therefore, can when excessively increasing, the diameter that suppresses input shaft 310 increase the maximum speed of revolution of rotating machine 200.
S. A. 110 only has an end directly to be supported by housing 12.The other end of S. A. 110 via input shaft 310 grades by housing 12 false bearings.Although with a plurality of positions of axle by housing 12 directly supporting situations by comparison effect be restricted, can obtain and the situation similar effects of S. A. 210.
In the example of Figure 11, bearing 210B1 is set in place between rotating machine 100 and 200, from the outstanding protrusion 12A of housing 12 inwalls.The advantage that this protrusion 12A is set is that the rigidity of housing 12 is improved and has reduced noise between actuating device 1 driver stage.
In the example of Figure 11, gear ring 530 is fixed on protrusion 12A place.The advantage here is further to have reduced the noise between actuating device 1 on-stream period.
In the example of Figure 11, although S. A. 110 and 210 supports by housing 12, also can be only by one of housing 12 supporting rotating shafts 110 and 210.
The present invention can realize to be different from the mode that specifies above, should be understood that the combination that the technical characterictic of above-mentioned each embodiment can be suitable.For example, the structure of the 6th embodiment can be applied to the actuating device of second to the 5th embodiment.
Although the present invention has been done detailed description and diagram, should understand very clearly that this only is illustrative and exemplary, and be not to be used for restriction that the spirit and scope of the present invention are only limited by appended patent claims.
