Enter axis 22.When clutch disk 31 is in neutral position, low-speed clutch 30A and high-speed clutch 30B are disconnected, motor 10
It is cut off with speed changer 20.In addition, clutch mechanism 30 is not limited only to friction clutch, such as it is also used as jaw clutch
Other clutches such as device and constitute.
Speed changer 20 has the input shaft 21 connecting with the clutch disc 32 of clutch mechanism 30, connect with clutch disc 33
Input shaft 22 and output shaft 23 with input shaft 21,22 configured in parallel.It is respectively formed in the outer peripheral surface of input shaft 21,22
There is the 1st gear 24,25.The 2nd gear 26,27 engaged with the 1st gear 24,25 is respectively formed in the outer peripheral surface of output shaft 23,
And it is formed with the 3rd gear 28.4th gear 29 is engaged with the 3rd gear 28.1st gear 24 and the 2nd gear 26 are respectively set as being suitble to
The number of teeth of the gear ratio run at a low speed, the 1st gear 25 and the 2nd gear 27 are respectively set as the tooth for the gear ratio for being suitble to run at high speed
Number.For example, the tooth number Z L of the 1st gear 24 of low speed is " 12 ", it is at a high speed " 24 " with the tooth number Z H of the 1st gear 25.
When low-speed clutch 30A connection, the rotation of rotary shaft 31a is using the 1st gear 24, the 2nd gear 26 with defined
Gear ratio carries out speed change, and output shaft 23 is rotated with low-speed high-torque.On the other hand, when high-speed clutch 30B links, rotary shaft
The rotation of 31a carries out speed change using the 1st gear 25, the 2nd gear 27 with defined gear ratio, and output shaft 23 is with the rotation of high speed low torque

The composition of fast device 20 is without being limited thereto, is also used as 1 grade of retarder, gear ratio can be switched to 3 grades or more speed changers
It constitutes.In addition, speed changer 20 is not limited to the gear mechanism of parallel axes, planetary gear mechanism is also used as to constitute.
In the vehicle that this mode is constituted, torque pulsation structurally is generated from the torque that motor 10 exports, and
The main reason for being generated as vibration, noise.So-called torque pulsation be by rotor 11 rotate when, due to the magnetic of magnet 11a
The interaction of the magnetic flux of logical and stator 12 coil 12b and generate non-uniform magnetic flux, and then the pulsation for generating torque shows
As.The case where motor 10 of present embodiment, rotor 11 rotate the torque arteries and veins for generating 6 times, i.e. 12 time of number of pole-pairs " 2 " every time
It is dynamic.
On the other hand, speed changer 20 here, pass through the 1st gear 24 and the 2nd gear 26 (or the 1st gear 25 and the 2nd gear
27) it engages and generates engagement torque.It engages in torque, each rotation generation of the 1st gear 24,25 is equivalent to the 1st gear 24,25
Tooth number Z L, ZH number cogging.In the present embodiment, the tooth number Z L of the 1st gear 24 of low speed is " 12 ", therefore
Rotation generates 12 cogging every time when running at a low speed.In addition, the tooth number Z H of the 1st gear 25 of high speed is 24, therefore high
Speed rotation generation 24 times cogging every time when driving.In addition, high speed is the 12 of number of pole-pairs " 2 " with the number of teeth of the 1st gear 25
Times.
Like this in the present embodiment, when running at a low speed, rotor rotates the number (torque of the torque pulsation of generation every time
The number of variation) it is consistent with the engagement number of cogging of torque.In addition, when running at high speed, engagement that rotor rotates every time
The number of the variation of torque is 2 times of the number of generation torque pulsation.It therefore, will in motor 10 and the 1st gear 24,25
The vibration frequency that should implement vibrationproof countermeasure is unified, so that the running and driving system as vehicle 100 can integrally make vibrationproof pair
The composition summary of plan.But tooth number Z L, ZH of the 1st gear 24,25 is only so corresponded into the frequency of torque pulsation and is set
It is fixed, have following problem.
Fig. 3 is to indicate that the rotation angle [deg] of the input shaft 21 with the output shaft 13 of motor 10 or speed changer 20 is opposite
Torque pulsation and engagement torque cogging (variation of torque [Nm]) an example figure.In figure, motor is shown
The cogging of 10 torque pulsation, the cogging of the engagement torque of the 1st gear 24 and torque pulsation and engagement torque
Resultant vibration.
Fig. 3 is 1 gear of rotation angle (magnetic pole phase) He Cong from the stipulated standard position of rotor 11 (output shaft 13)
The example when phase difference θ of the rotation angle (mesh phase) of the stipulated standard position of 24 (input shafts 21) is 0 °.So-called phase
Poor θ refers to the angle of the base position of 1st gear 24 opposite with the base position of rotor 11.
Fig. 4 A is the figure for the base position for illustrating the rotation angle of rotor 11.When rotor 11 is in base position, from
Axis CL1 by the circumferencial direction center of magnet 11a and to the straight line (rotor reference line CL11) radially extended and passes through axis
CL1 is consistent with straight line (the stator reference line CL12) at the circumferencial direction center of the coil 12b of stator 12.As an example, this
When reference line CL11 and CL12 formed angle θ 1 be 0 °, by the coil of magnetic flux (magnetic pole) and stator 12 of the magnet 11a of rotor 11
The interaction of the magnetic flux of 12b, magnetic flux become peak (maximum value) that is close, and then generating torque pulsation.
Fig. 4 B is the figure for the base position for illustrating the rotation angle of the 1st gear 24.1st gear 24 is in base position
When, the 1st gear 24 that the 1st gear 24 is abutted with the 2nd gear 26 is extended to from the rotation center (axis CL2) of the 1st gear 24
Abutted position P1's on the flank of tooth straight line (the 1st gear basic line CL21) and the rotation center that passes through axis CL2 and the 2nd gear 26
(axis CL3) straight line (the 2nd gear basic line CL22) it is consistent.At this point, the angle θ 2 that reference line CL21 and CL22 are formed is 0 °,
The flank of tooth of 1st gear 24 abuts (engagement) with the flank of tooth of the 2nd gear 26, and generates the peak (maximum value) of engagement torque.
It therefore, in the example shown in Fig. 3, is 0 ° as θ 1 and the phase difference θ of the difference of θ 2, the cogging of torque pulsation
Phase and the engagement phase of cogging of torque it is consistent (resonance), the increase of the size of resultant vibration.If wanting for example to pass through
Vibration isolation member inhibits the vibration of such case then to need the vibration isolation member of high price, and then leads to cost increase.In addition, vibrationproof structure
The thickness of part increases, and the restriction in layout can probably become larger.Therefore, in the present embodiment, in order to effective with the composition of low price
Ground inhibits resultant vibration, as under type constitutes equipment for inhibiting of vibration.
Fig. 5 is the block diagram for indicating the outline structure of equipment for inhibiting of vibration 200 of an embodiment of the present invention.As shown in figure 5,
Equipment for inhibiting of vibration 200 includes rotor rotation sensors 51, gear rotation sensor 52,53, controller 60 and control valve
30a.In addition, be conceived to the cogging of the engagement torque of the 1st gear 24 of torque pulsation and low speed of motor 10 below
Relationship is illustrated to vibration is reduced.
The decomposer of angle of the rotor rotation sensors 51 for example including detection output shaft 13.More specifically, such as Fig. 1 institute
Show, rotor rotation sensors 51 are configured at around the output shaft 13 of rotor 11, are detected from the defined base position of rotor 11
Rotation angle (magnetic pole phase).
The optics of angle of the gear rotation sensor 52,53 for example including the input shaft 21,22 for detecting speed changer 20 respectively
Formula, magnetic rotation sensor.More specifically, as shown in Figure 1, gear rotation sensor 52,53 be respectively arranged at input shaft 21,
Around 22, the rotation angle (mesh phase) from the defined base position of the 1st gear 24,25 is detected respectively.
Signal from rotor rotation sensors 51 and gear rotation sensor 52,53 is input into controller 60.In addition to
Other than signal from rotor rotation sensors 51 and gear rotation sensor 52,53, passed from the speed for being loaded into vehicle 100
The output of the various sensors such as sensor also enters into controller 60.
Controller 60 includes the electronic control unit (ECU) for being loaded into vehicle 100.Controller 60 controls as a whole
Traveling motor 10, speed changer 20 vehicle 100 synthesis ECU and constitute.In addition it is possible to which Motor Control use is respectively set
ECU, the transmission control multiple ECUs different with functions such as ECU.As shown in figure 5, controller 60 includes to have the operational parts such as CPU
61, ROM, the computer of the storage unit 62 of RAM, hard disk etc. and other peripheral circuits (not shown).
Operational part 61 is used as functional structure, has engagement instruction department 611, clutch control portion 612.Engage instruction department
611 make the instruction that clutch mechanism 30 links to low-speed position engagement, i.e. low-speed clutch 30A.In the present embodiment, make
The generation number (12 times) for the torque pulsation that the tooth number Z L and rotor 11 of the 1st gear of low speed rotate every time is consistent.Therefore, work as low speed
When clutch 30A links, the generation number (number of cogging) of the torque pulsation that rotor rotates every time and torque is engaged
The number of variation is consistent.In addition, engagement instruction department 611 also makes the instruction of high-speed clutch 30B connection.
Clutch control portion 612 controls control valve 30a according to the engagement instruction of engagement instruction department 611, and controls clutch
The movement of mechanism 30.Especially when making the instruction of low-speed clutch 30A connection by engagement instruction department 611, clutch control
Portion 612 controls the movement of clutch mechanism 30, so that the phase difference θ of magnetic pole phase and mesh phase becomes specified value θ A.At this
In embodiment, as previously discussed, when the phase difference θ of magnetic pole phase and mesh phase is 0 °, output shaft 13 and input shaft 21
Base position by torque pulsation and engagement torque cogging resonance in a manner of set.Therefore, it is specified that value θ A to meet under
The mode for stating calculation formula (I) is set.
θ A=(2n+1) × 180 °/ZL ... (I)
Wherein, n is integer.
Such as in above-mentioned calculation formula (I) when n=0, it is specified that value θ A be 15 ° (=180 °/ZL).At this point, the torque pulsation of Fig. 3
Waveform offsets from each other half-phase with the waveform for the cogging for engaging torque, that is, becomes mutually opposite phase, therefore, torque pulsation
Cogging with engagement torque can cancel out each other.
Fig. 6 is the program indicated according to storage unit 62 (Fig. 5) is pre-stored in, at 612 implementation of clutch control portion
The flow chart of one example of reason.It handles shown in the flow chart and is for example started according to the connection that engine key switchs, with rule
The fixed period implements repeatedly.
Firstly, determining whether to be made that low-speed clutch 30A is engaged by engagement instruction department 611 at S1 (S: processing step)
Instruction.It is repeated until S1 is affirmative.Enter S2 when S1 is (S1: yes) certainly, and exports and control to control valve 30a
Signal processed keeps clutch disk 31 mobile to the direction A of Fig. 1 and links low-speed clutch 30A.Next, in S3 according to carrying out rotation
The signal of sub- rotation sensor 51 and gear rotation sensor 52 detects the magnetic pole phase of rotor 11 and the engagement of the 1st gear 24
The phase difference θ of phase.
Next, in S4, determine magnetic pole phase and whether mesh phase be opposite phase, i.e., the magnetic pole phase of rotor 11 and
Whether the phase difference θ of the mesh phase of the 1st gear 24 meets above-mentioned calculation formula (I).Terminate to locate the case where S4 is (S4: yes) certainly
Reason then enters S5 when negating (S4: no).
In S5, exported in such a way that clutch disk 31 is relative to the sliding of clutch disc 32 and relative rotation to control valve 30a
Signal is controlled, pressing force of the clutch disk 31 relative to clutch disc 32 is weakened.That is, sliding low-speed clutch 30A, and adjust
The phase difference θ of magnetic pole phase and mesh phase.In addition, the slippage of such case can weaken the degree of pressing force by control
(hydraulic), the time for weakening pressing force are adjusted.After S5 carries out adjusting offset, return to S2, until magnetic pole phase and
Until mesh phase becomes opposite phase, same processing is repeated.
It, can be according to the letter from rotor rotation sensors 51 and gear rotation sensor 52 in the adjusting offset of S5
Number, the slippage of clutch disk 31 is adjusted, so that phase difference θ becomes the specified value θ A as target phase difference.That is, utilizing feedback
It controls to control the movement of low-speed clutch 30A.
The movement of present embodiment is further illustrated.Fig. 7 is the movement for indicating equipment for inhibiting of vibration 200
The timing diagram of one example.As shown in fig. 7, in time point t1, it is defeated when driver carries out the gear shift operation for starting running
Enter engagement instruction (connection), low-speed clutch 30A links (S1, S2).In time point t2, when judgement magnetic pole phase and mesh phase
When not being opposite phase (such as 0 ° of phase difference), low-speed clutch 30A slides the stipulated time.Magnetic pole phase and engagement phase as a result,
The phase difference θ of position changes.Later, link (S5, S2) again in time point t3, clutch 30A.
In time point t4, when determining magnetic pole phase and mesh phase for opposite phase (such as 15° out of phase), maintain low
The connecting state of speed clutch 30A.As a result, as shown in Figure 8 A, the cogging of torque pulsation is engaged the cogging of torque
It offsets, the resultant vibration of running and driving system entirety reduces.In addition, in fig. 8 a, by the torque of torque pulsation and engagement torque
It changes and is enumerated as identical torque amplitude, but these torque amplitudes need not be consistent.Torque pulsation and engagement torque
The amplitude ratio of any one of cogging another amplitude it is big when, the amplitude of resultant vibration cannot be 0.But this feelings
Same under condition, the cogging of torque pulsation and engagement torque is cancelled out each other, therefore also can reduce running and driving system entirety
Vibration.
More than, for make the phase difference θ of the magnetic pole phase of rotor 11 and the mesh phase of the 1st gear 24 become specified value θ A and
Phase adjustment (S4, S5) has been carried out, still, instead of this adjustment, the phase difference θ of magnetic pole phase and mesh phase can also have been carried out
Adjustment so that phase difference θ is relative to specified value θ A in prescribed limit θ B.Prescribed limit θ B は, it tests etc., surveys in advance
Surely the resultant vibration of the cogging of the torque pulsation when phase difference θ of change magnetic pole phase and mesh phase and engagement torque,
And determine that the torque amplitude TA of resultant vibration becomes the value (such as ± 5 °) such as permissible value according to measurement result.By the allowed band
It is stored in storage unit 62 as factory shipment value, replaces being made whether the judgement for opposite phase in S4, and determines phase difference θ phase
For specified value θ A whether in prescribed limit θ B.
Fig. 8 B is an example of the vibrational waveform of such case.It is further demonstrated that by Fig. 8 B, in this case, torque
The cogging of pulsation and engagement torque is cancelled out each other, and can reduce the vibration of running and driving system entirety.
Using present embodiment, following function and effect can be played.
(1) vehicle 100 includes traveling motor 10, stator 12 with rotor 11 and with winding, intermeshing
