[0037]
As shown in FIG. 7, the power supply connection terminal 50 includes a U-phase power supply connection terminal portion 50a, a V-phase power supply connection terminal portion 50b, and a W-phase power supply connection terminal portion 50c. Two sets are arranged and fixed at different positions in the circumferential direction of the motor case 2 (case member) that defines the chamber 30.
[0038]
The busbar radial laminated body 51 is disposed in the gear chamber 30, and is fixed to the U-phase plate 51a, the V-phase plate 51b, and the W-phase plate 51a, which are fixed to the end of each of the power supply connection terminals 50a, 50b, and 50c on the side of each gear chamber. And a phase plate 51c. Each plate 51a, 51b, 51c made of a conductive material such as copper is radially overlapped with a predetermined gap therebetween, and the entire area including the gap is covered with an insulating resin 51d to form a square cross section. Have been.
[0039]
As shown in FIG. 7, the bus bar radial laminated body 51 corresponds to two sets of power supply connection terminals 50, 50, and is located at a radially outer peripheral position of the output gear 11, and has an outer diameter shape of the output gear 11.

[Basic function of multi-axis multi-layer motor]
By employing a multi-axis multilayer motor M in which two magnetic lines of force, the outer rotor magnetic field lines and the inner rotor magnetic field lines, are formed with two rotors and one stator, the coil 42 and a coil inverter (not shown) can be replaced by two inner rotor IRs and an outer rotor. Can be shared for OR. Then, by applying to the single coil 42 a composite current obtained by superimposing the current for the inner rotor IR and the current for the outer rotor OR, the two rotors IR and OR can be controlled independently. That is, although it is one multi-axis multilayer motor M in appearance, different or similar functions of the motor function and the generator function can be used as a combination.
[0044]
Therefore, for example, it is much more compact than when a motor having a rotor and a stator and a generator having a rotor and a stator are provided, which is advantageous in terms of space, cost, and weight, and allows the coil to be shared. Thereby, loss (copper loss, switching loss) due to current can be prevented.
[0045]
In addition, the present invention has a high degree of freedom of selection such that not only the usage of (motor + generator) but also the usage of (motor + motor) and (generator + generator) can be performed only by the composite current control. When adopted as a drive source for a hybrid vehicle as in the embodiment, the most effective or efficient combination can be selected from these many options according to the vehicle state.
[0046]
[Mounting work of motor coil power supply structure]
In the case where a conventional multi-layer motor is employed in a hybrid drive unit, three power supply lines, a U-phase power supply line, a V-phase power supply line, and a W-phase power supply line, taken out of the multi-layer motor are connected from the front side of the stator. When the feeder is taken out to the planetary gear mechanism side, since the three feeder lines are separated from each other, it is necessary to route the feeder lines and to insulate the connecting portions of the feeder lines, resulting in poor assembling workability. .
[0047]
On the other hand, the motor coil power supply structure of the first embodiment employs, instead of the conventional power supply line, a busbar radial laminated body 51 having a predetermined shape and an insulating property as an electric power supply member by an insulation molding process. In addition, it is unnecessary to carry out the wiring work of the power supply line and the insulation work, and it is possible to obtain good assembling workability.
[0048]
[Cooling action of power supply busbar parts]
When the bus-bar radial laminated body 51 is used as a power supply member in the multi-axis multi-layer motor M incorporated in the hybrid drive unit, a large current needs to flow through each plate 51a, 51b, 51c of the bus-bar radial laminated body 51. Therefore, there is a problem that the bus bar radial direction laminate 51 itself generates heat.
[0049]
On the other hand, since the busbar radial laminated body 51 is arranged at the radial outer peripheral position of the rotating output gear output gear 11 in the gear chamber 30 and along the outer diameter shape of the output gear 11, the busbar rotates. The lubricating oil splashed by the output gear 11 impinges on the bus bar radial laminated body 51 to effectively suppress heat generation of the bus bar radial laminated body 51 even when a large current flows through the plates 51a, 51b, 51c. Can be.
[0050]
Next, effects will be described.
In the motor coil power supply structure of the hybrid drive unit of the first embodiment, the following effects can be obtained.
[0051]
(1) In a hybrid drive unit including an engine E, a multi-shaft multi-layer motor M, a Ravigneaux type compound planetary gear train G, and a drive output mechanism D, a stator S and a rotor IR of the multi-shaft multi-layer motor M are provided. The motor chamber 17 accommodating the OR and the gear chamber 30 accommodating the Ravigneaux-type compound planetary gear train G and the drive output mechanism D are arranged adjacent to each other, and a power supply structure for the coil 42 of the multi-axis multilayer motor M is provided. A power supply connection terminal 50 provided in the motor case 2 defining the gear chamber 30, a bus bar radial direction laminated body 51 disposed in the gear chamber 30, and a partition wall 2a between the gear chamber 30 and the motor chamber 17. And the busbar radial laminated body 51 is disposed at a radially outer peripheral position of the rotating output gear 11 in the gear chamber 30. Neither the wiring work of the power supply line nor the insulation treatment work is required, and good assembling workability can be obtained, and the heat generation of the power supply member can be effectively suppressed even when a large current flows through the power supply member.
[0052]
(2) Since the busbar radial laminated body 51 is shaped so as to conform to the outer diameter shape of the rotating output gear 11 in the gear chamber 30, the lubricating oil from which the rotating output gear 11 has jumped causes the busbar radial laminated body. 51, and a high cooling action can be obtained.
[0053]
(3) The motor is disposed on the stator S as a fixed armature wound with the coil 42, the outer rotor OR having the outer rotor magnet 61 embedded therein and the inner rotor disposed on the outer side of the stator S. A multi-axis multi-layer motor M having an inner rotor IR having a magnet 21 embedded therein and having two motor-generator functions in spite of being a single motor. The temperature rise of the coil 42 of the motor M can be suppressed.
[0054]
That is, since the multi-shaft multilayer motor M is incorporated in the hybrid drive unit, a large current is frequently applied to the coil 42 of the multi-shaft multilayer motor M in order to generate a required torque. On the other hand, by effectively suppressing the heat generation of the busbar radial laminated body 51 as the power supply member, it is possible to suppress the temperature rise of the coil 42 existing at the extended position of the busbar radial laminated body 51.
[0055]
(4) The planetary gear mechanism includes a common carrier C that supports the first pinion P1 and the second pinion P2 that mesh with each other, a first sun gear S1 that meshes with the first pinion P1, and a second sun gear S2 that meshes with the second pinion P2. , A second ring gear R2 meshing with the second pinion P2, and a Ravigneaux-type compound planetary gear train G having at least four rotating elements. The hybrid drive unit connects the second ring gear R2 and the engine output shaft 5, and The sun gear S1 is connected to the first motor hollow shaft 8, the second sun gear S2 is connected to the second motor output shaft 9, and the output gear 11 is connected to the common carrier C. The bus bar radial direction laminated body 51 is arranged at the outer circumferential position in the direction, so that the output gear that scatters oil among the constituent elements of the hybrid drive unit is provided. The heat generation of the bus bar radial direction laminated body 51 can be effectively suppressed when necessary by using the hook 11.
[0056]
That is, at the time of acceleration running or the like in which a large current flows through the bus bar radial laminated body 51, the output gear 11 rotates, and the lubricating oil that jumps up has a high cooling effect on the bus bar radial laminated body 51. On the other hand, when the vehicle stops to stop supplying power to the bus bar radial laminate 51, the output gear 11 also stops, and the cooling effect of the bus bar radial laminate 51 is not exhibited. In this way, by using the output gear 11, the cooling request for the bus bar radial direction laminated body 51 is satisfied.
[0057]
As described above, the motor coil power supply structure of the hybrid drive unit according to the present invention has been described based on the first embodiment. However, the specific configuration is not limited to the first embodiment, and is not limited to the first embodiment. Changes and additions to the design are permitted without departing from the spirit of the claimed invention.
[0058]
For example, in the first embodiment, an example of a three-layer multi-axis multilayer motor having two rotors and one stator has been described as a motor. However, the motor has one rotor and one stator synchronous motor, two or more rotors, and two or more stators. The present invention can be applied to a multi-axis multilayer motor. Further, the present invention can be applied to a coil power supply structure of a motor other than the synchronous motor.
