Internal combustion engine E makes driving wheel W rotate as a result,.
As described above, in the present embodiment, have to transmit from the 1st electric rotating machine M1 to the power of output shaft OS and connect The 2nd for connecing or cutting off cuts off bindiny mechanism C2 and will transmit connection or cut-out from the 2nd electric rotating machine M2 to the power of output shaft OS The 3rd cut-out bindiny mechanism C3.There is internal combustion engine E, the 1st electric rotating machine M1 and the 2nd electric rotating machine as power source as a result, In the hybrid vehicle 1 of M2, internal combustion engine E work is only set to be carried out to output shaft OS in the 1st cut-out bindiny mechanism C1 of connection In the case that power transmits, by the 2nd cut-out bindiny mechanism C2 of cut-out and the 3rd cut-out bindiny mechanism C3, and the 1st rotation can be made Motor M1 and the 2nd electric rotating machine M2 will not interlock rotation relative to output shaft OS.Therefore, internal combustion engine E work is only made to come to defeated In the case that shaft OS is transmitted into action edge, load can be mitigated, so as to seek to improve fuel efficiency.
In addition, by configuring the 1st rotary shaft S1 and the 2nd rotary shaft S2 on common rotation axis, and can prevent The diametrical device enlargements of 1st rotary shaft S1 or the 2nd rotary shaft S2.
In addition, by by the 1st rotary shaft S1, the 2nd rotary shaft S2, the 3rd rotary shaft S3 and the 4th rotary shaft S4 in parallel to each other Configuration, and the length in axial direction can be inhibited.
In addition, by becoming, reaching the 1st cut-out bindiny mechanism C1, (it will be passed from internal combustion engine E to the power of output shaft OS Pass connection or cut-out) before via the structure of the 4th rotating mechanism 24, and the length in axial direction can be inhibited and obtain being based on the 4th The reduction ratio of rotating mechanism 24.
In addition, by the action of the 2nd cut-out bindiny mechanism C2, can optionally switch from the 1st electric rotating machine M1 to the 1st The power of rotating mechanism 21 is transmitted and is transmitted from the 1st electric rotating machine M1 to the power of the 2nd rotating mechanism 22.Therefore, it is possible to the 1st Two stage speed change is set between electric rotating machine M1 and output shaft OS.In addition, by the 2nd cut-out bindiny mechanism C2 of switching, and being capable of needle Still it is that generator switches over to making the function of the 1st electric rotating machine M1 be motor.
In addition, by the action of the 3rd cut-out bindiny mechanism C3, can optionally switch from the 2nd electric rotating machine M2 to the 1st The power of rotating mechanism 21 is transmitted and is transmitted from the 2nd electric rotating machine M2 to the power of the 3rd rotating mechanism 23.Therefore, it is possible to the 2nd Two stage speed change is set between electric rotating machine M2 and output shaft OS.In addition, by the 3rd cut-out bindiny mechanism C3 of switching, and being capable of needle Still it is that generator switches over to making the function of the 2nd electric rotating machine M2 be motor.
In addition, by the action of the 1st cut-out bindiny mechanism C1, allow hand over from the 4th rotating mechanism 24 to the 5th rotating mechanism Connection that the power of 25 and the 6th rotating mechanism 26 transmits and from the 4th rotating mechanism 24 to the 5th rotating mechanism 25 and the 6th whirler The cut-out that the power of structure 26 transmits.It is transmitted therefore, it is possible to switch from internal combustion engine E to the power of output shaft OS.In addition, passing through combination 1st cut-out bindiny mechanism C1, the 2nd cut-out bindiny mechanism C2 and the 3rd cut off the action of bindiny mechanism C3 and can be directed to the 1st rotation Motor M1 and the 2nd electric rotating machine M2 makes it have the function of motor and generator both sides.
In addition, being slowed down than the 2nd of the 2nd power transfer path by being configured the 1st reduction ratio of the 1st power transfer path Than big, and the 1st rotation can be inhibited compared with the 2nd electric rotating machine M2 as defined in being transmitted to output shaft OS in the case of power The output of motor M1.
If in addition, being configured the 3rd reduction ratio of the 3rd power transfer path than appointing in the 1st reduction ratio and the 2nd reduction ratio It is one small and when output shaft OS high rotates use internal combustion engine E, then can improve fuel efficiency.
In addition, by as make the 1st electric rotating machine M1 output more than the 2nd electric rotating machine M2 output as structure, And the 1st electric rotating machine M1 is used in the low-speed region of hybrid vehicle 1, and can make the 2nd electric rotating machine M2 miniaturization or Lightweight.
If in addition, structure as the output phase etc. as the output and the 2nd electric rotating machine M2 that make the 1st electric rotating machine M1, It is identical structure that the 1st electric rotating machine M1 and the 2nd electric rotating machine M2, which can then be made, so as to seek sharing for major part Change.
In addition, by the way that the 1st rotary shaft S1 is configured the radially inner side in the 2nd hollow rotary shaft S2, and can will configure The 2nd electric rotating machine M2 of the 1st electric rotating machine M1 and configuration on the 2nd rotary shaft S2 on the 1st rotary shaft S1, which is more concentrated at, to be matched It sets on common rotation axis, so as to prevent device enlargement radially.
If in addition, as by the operation implemented based on i.e. the 2nd switching mechanism 32 of a switching mechanism come linkedly to the 2nd The structure that the cut-outs of cut-out bindiny mechanism C2 and the 3rd bindiny mechanism C3 is operated, then can reduce amount of parts.
If, can be from the 1st electric rotating in addition, independently operated to the 1st switching mechanism 31 and the 2nd switching mechanism 32 Machine M1 and the 2nd electric rotating machine M2 independently operate the action of internal combustion engine E.
