Also, on each countershaft 9L, the 9R of the left and right for offsetting up ground arranged in series in upper and lower and front and back each other,
Be respectively fixed with the different gear 16,17 of diameter, each gear 16 of major diameter side respectively be individually fixed in left and right motor drive shaft
The gear 8 of 3L, 3R engage.Here, the diameter ratio for being individually fixed in the gear 16 of each countershaft 9L, 9R around is individually fixed in
The diameter of the gear 8 of each motor drive shaft 3L, 3R is big, these gears 8,16 constitute train of reduction gears.
In addition, being respectively fixed with big between the bearing 13 and 14 of output shaft 10L, 10R of the left and right of arranged coaxial
The gear 18 of diameter, each gear 18 are engaged with the gear 17 for being fixed on the path side of each countershaft 9L, 9R around respectively.Here, respectively
It is fixed on the straight of gear 17 of the diameter of the gear 18 of each output shaft 10L, 10R around than being individually fixed in each countershaft 10L, 10R
Diameter is big, these gears 17,18 constitute train of reduction gears.
Here, the actual state of the axis configuration structure of the invention in electric drive unit 1 is shown in Fig. 3~Fig. 6, such as this
Shown in a little figures, the countershaft 9R on right side is deviating downwards ε 1 (referring to Fig. 6) and to before vehicle relative to the countershaft 9L configuration in left side
The position of side (right of Fig. 6) offset ε 2.In addition, in the present embodiment, as shown in Fig. 3~Fig. 5, supporting each countershaft 9L, 9R
The bearing 12 of axial outer end portion be contained in the inside of gear 16 without being exposed to outside.
In electric drive unit 1 as constructed as above, when motor 2L, 2R power supply to the left and right starts them respectively
When, the rotation of each motor drive shaft 3L, 3R are decelerated via the gear 8 and gear 16 for constituting train of reduction gears and are transmitted to left and right
Each countershaft 9L, 9R, each countershaft 9L, 9R are driven in rotation respectively with defined speed.Also, the rotation of countershaft 9L, 9R of left and right
Each output shaft 10L, 10R of left and right are decelerated and are transmitted to via the gear 17 and gear 18 that constitute train of reduction gears, it is each to export
Axis 10L, 10R are driven in rotation respectively with defined speed.Therefore, the rotation of each motor drive shaft 3L, 3R of motor 2L, 2R of left and right
Turn to be decelerated two-stage via countershaft 9L, 9R of left and right and be transferred to output shaft 10L, 10R of left and right respectively, electronic equipped with this
In the hybrid vehicle HEV shown in FIG. 1 of driving unit 1, can from the output shaft 10L of the left and right of electric drive unit 1,
The axle of 10R to the left and right separately transmitting rotary power, to rotate the rear-wheel WR (referring to Fig.1) of driving left and right.
In the axis configuration structure of electric drive unit 1 discussed above, as described above, making countershaft 9L, 9R of left and right
Therefore offsetting up ground arranged in series in upper and lower and front and back as shown in Fig. 4, Fig. 5 and Fig. 7, can make to support these countershafts
The bearing 11 of each axial inner end of 9L, 9R overlappingly configures in the axial direction.That is, even if two bearings 11 are axially disposed
Identical position, they will not be interfered with each other.As a result, axis configuration structure involved according to the present invention, can not change
The axial dimension for becoming the length of countershaft 9L, 9R for controlling and making countershaft 9L, 9R of these left and right in shell 7 shortens a bearing
The amount of 11 width.Hereinafter, being illustrated according to Fig. 7 to the situation.
Fig. 7 is the schematic diagram of countershaft 9L, 9R from face side, in previous axis configuration structure shown in Fig. 8, is such as schemed
Shown in 7 (a), due to countershaft 109L, 109R arranged coaxial of left and right, so needing to avoid supporting it in a manner of it can rotate
Inside two bearings 111 between interference and they are set side by side in the axial direction.Therefore, when include bearing 111,
When the length of each countershaft 109L, 109R of 112 left and right are set as L as shown in the figure, these countershafts 109L, 109 are in (the ginseng of shell 109
According to Fig. 8) in shared axial length L 2 be
L2=L+L=2L ... (1)
In contrast, in axis configuration structure of the present invention, as shown in (b) of Fig. 7, by countershaft 9L, 9R of left and right
ε 1, with deviating ε 2 (referring to Fig. 6) in the longitudinal direction arranged in series are deviated in the up-down direction, so not having to consider to support each pair
The interference of the bearing 11 of the inside of axis in the axial direction, can be such that the two bearings 11 overlappingly configure in the axial direction (in the axial direction
It is configured at same position).Therefore, when the length of left and right countershaft 9L, 9R and previous countershaft 109L, 109R are also set up as L
When, length L1 these countershafts 9L, 9R shared in shell 7 (referring to Fig. 2 and Fig. 6) shortens the width W of a bearing 11, following formula
Shown in relationship set up.
L1=L2-W ... (2)
Therefore, countershaft 9L, 9R of left and right can be configured knot relative to previous axis by axis configuration structure according to the present invention
The amount that countershaft 109L, 109R of left and right in structure move inward W/2 in the axial direction is configured (referring to (b) of Fig. 7), adjoint
In this, Fig. 2~left and right shown in fig. 6 motor drive shaft 3L, 3R and output shaft 10L, 10R can also similarly in the axial direction inwardly
The amount of mobile W/2 is configured.As a result, the width dimensions of the electric drive unit 1 including shell 7 can be shortened one
The width W of bearing 11, can be realized the miniaturization of the electric drive unit 1, to improve the electric drive unit 1 to Fig. 1 institute
The mountability of the hybrid vehicle HEV shown.
In addition, in the above embodiment, being configured to the axis in the electric drive unit for being equipped on hybrid vehicle
Structure is illustrated, but the present invention similarly can be applied to be mounted in such as electric vehicle other than hybrid vehicle
The axis of electric drive unit or the electric drive unit being arranged on the device other than vehicle on (EV vehicle) configures knot
Structure.
In addition, in the above embodiment, using the motor drive shaft by double reduction gearing group to left and right motor
Rotation slow down and the structure of output shaft transmitting to the left and right, but as deceleration mechanism, planetary gear machine also can be used
Structure etc..
Also, the present invention is not limited to apply in the implementation described above, in claims and say
Various modifications are able to carry out in the range of technical idea documented by bright book and attached drawing.
