Easily it is equipped on vehicle or being capable of advantage as lightness.
The content of the invention
Therefore, one of problem of the invention is, for example, the speed changer for obtaining further minimizing in the axial direction.
The speed changer of the present invention for example possesses：First input shaft, is fixed with multiple drive gears thereon；Second input shaft,
Multiple drive gears are fixed with thereon, it is concentric and cover above-mentioned first input shaft with above-mentioned first input shaft；First clutch, its
Switch the connection and cut-out of above-mentioned first input shaft and driving source；Second clutch, its switch above-mentioned second input shaft with it is above-mentioned
The connection and cut-out of driving source；First output shaft, is provided with the way of it can rotate integrally is nibbled with above-mentioned drive gear thereon
The multiple driven gears closed；Second output shaft, is provided with the way of it can rotate integrally is engaged with above-mentioned drive gear thereon
Multiple driven gears；Multiple first choice mechanisms, they have movable part, and the movable part is configured to connecting above-mentioned
The cut-out position of driven gear and the link position and the above-mentioned driven gear of cut-out and above-mentioned first output shaft of above-mentioned first output shaft
Moved between putting；Multiple second selection mechanisms, they have movable part, and the movable part is configured to connecting above-mentioned driven
The link position of gear and above-mentioned second output shaft and cut off above-mentioned driven gear and above-mentioned second output shaft off-position it
Between move；Idle pulley unit, it is abreast set with above-mentioned first input shaft, above-mentioned first output shaft and above-mentioned second output shaft,
The first idle pulley for being engaged with the above-mentioned drive gear with reverse gear shift and rotated integrally with above-mentioned first idle pulley and with above-mentioned reversing
Second idle pulley of the above-mentioned driven gear engagement of gear；And park lock gear, it is fixed on above-mentioned second output shaft, is set
For that can be engaged with the engaging piece for the parking device for being supported in housing, the above-mentioned driven gear of reverse gear shift be configured to
Above-mentioned first output shaft is rotated integrally, and the above-mentioned driven gear of the second shift gear is configured to and above-mentioned second output shaft one
Body rotates, and the above-mentioned drive gear shared in reverse gear shift and the second shift gear is fixed on above-mentioned second input shaft, above-mentioned parking
The driven gear of lock gear and above-mentioned reverse gear shift is configured in the way of the arranged radially along above-mentioned first output shaft, is switched above-mentioned
The above-mentioned first choice mechanism of connection and the cut-out of the driven gear of reverse gear shift and above-mentioned first output shaft and it is above-mentioned fall
The drive gear shared in car bumper and the second shift gear is configured in the way of the arranged radially along above-mentioned second input shaft.
Thus, in above-mentioned speed changer, the diameter of the drive gear shared in reverse gear shift and the second shift gear is smaller,
So the first choice mechanism of reverse gear shift and the drive gear shared in reverse gear shift and the second shift gear can be avoided easily
Interference.In addition, arranged radially of the driven gear of park lock gear and reverse gear shift along the first output shaft.Therefore, according to upper
Speed changer is stated, park lock gear, the driven gear of reverse gear shift can be more compactly configured vertically, is become in reverse gear shift and second
The drive gear and the first choice mechanism of reverse gear shift shared in speed gear.
In addition, in above-mentioned speed changer, for example above-mentioned second shift gear driven gear be provided be inserted into it is above-mentioned
The recess of the above-mentioned movable part of second selection mechanism, above-mentioned second selection mechanism switch the driven gear of above-mentioned second shift gear with
The connection and cut-out of above-mentioned second output shaft.In i.e. above-mentioned speed changer, the movable part being axially moveable can be incorporated in recessed
In portion.
Thus, according to above-mentioned speed changer, driven gear, the second change of the second shift gear can be more compactly configured vertically
Second selection mechanism of speed gear.

The drive gear 13 of the shift gear of first choice mechanism 951 and the 3rd of the driven gear 35 of five shift gear is with along the first input shaft
The mode of 10 arranged radially is configured.Drive gear 15 of the diameter than the 5th shift gear of the drive gear 13 of 3rd shift gear
Diameter is small, so in the present embodiment, the drive gear of the shift gear of first choice mechanism 951 and the 3rd of the 5th shift gear
13 can be radially arranged.In the present embodiment, by such arrangement, drive gear 15, the 5th shift gear can be made
Driven gear 35, first choice mechanism 951 and drive gear 13 are more compactly configured vertically.
The drive gear 246 of (4) the 4th shift gear and the 6th shift gear share
The common drive gear 246 in the 4th shift gear and the 6th shift gear.Thus, with becoming in the 4th shift gear and the 6th
Set the structure of drive gear to compare respectively in speed gear, the structure of the 4th shift gear and the 6th shift gear can be made vertically more
Compactly configure.In addition, gear ratio between the 4th shift gear and the 6th shift gear is poor smaller, so in the presence of the second input
The advantages of arrangement of the output shaft 30 of axle 20 and first and the second output shaft 40 becomes easy.In addition, in the present embodiment, the
Six shift gear be minimum number of teeth in the shift gear of even number than shift gear, the 4th shift gear is only secondary in the shift gear of even number
In minimum number of teeth than gear ratio shift gear.In addition, be only second in the shift gear of even number minimum number of teeth than gear ratio change
Speed gear refer in the shift gear of even number except minimum number of teeth than shift gear in addition to remaining shift gear in minimum number of teeth
The shift gear of the even number of ratio.
In addition, as described above, in the present embodiment, first in the less final gear 3F fixations of the confession number of teeth is defeated
The driven gear 31 of the first shift gear is provided with shaft 30 in the way of it can rotate integrally, and for the more end of the number of teeth
The driven gear of the 6th shift gear is provided with the second output shaft 40 that travelling gear 4F is fixed in the way of it can rotate integrally
46.Therefore, according to present embodiment, between the first shift gear and final gear are the 6th shift gear, the difference of gear ratio can be made
It is bigger.
