233 rotation and rotate.Internal rotor 23 carries out rotation driving, and thus outer rotor 22 is driven.
The rotary shaft 233 of internal rotor 23 is fixed in internal rotor 23 to penetrate through the state of internal rotor 23, and is linked to not
Prime mover of diagram is rotated using the torque from prime mover.The rotary shaft 233 of internal rotor 23 has relative to outer rotor
The position relationship of 22 axis of rotation biasing.Specifically, outer rotor 22 and the gap of internal rotor 23 are configured to, in outer rotor 22
It is narrow at the part engaged with internal rotor 23, the side opposite with position of engagement 180 degree centered on by the axle center of outer rotor 22
It is wide at position, the part that i.e. outer rotor 22 does not engage with internal rotor 23.
The part that outer rotor 22 above-mentioned is engaged with internal rotor 23 is approximately fixed relative to the position of shell 21.Relative to this
The position of engaging portion, in the upstream side of the rotation of outer rotor 22 and internal rotor 23, the sky between outer rotor 22 and internal rotor 23
Between become larger, become the suction side of ATF, ATF is inhaled into the space.In addition, relative to the position of engagement, in outer rotor 22
With the downstream side of the rotation of internal rotor 23, the space between outer rotor 22 and internal rotor 23 tapers into, and becomes the discharge of ATF
Side, ATF are discharged from the space.The part for carrying out the discharge of trochoid pump 20 constitutes oily discharge unit 201.This is discharged
The hydraulic pressure of ATF is transported to the hydraulic control portion for being controlled the speed changer for constituting transmission mechanism.
In addition, engaging by internal rotor 23 and outer rotor 22, rotary shaft of the oil containing a large amount of bubbles from internal rotor 23
Shell 21 between the rotary shaft 233 and internal rotor 23 of internal rotor 23 on the end face of near 233, internal rotor 23 axial direction
Part be discharged.The part constitutes bubbles oil discharge unit 202.
Wind deflector 50 has cylindrical shape, and is configured around the rotary shaft 233 of internal rotor 23.The axis of wind deflector 50
The portion of shell 21 that upward one end 51 is configured and is fixed near the bubbles oil discharge unit 202 of trochoid pump 20
Point.The other end 52 in the axial direction of wind deflector 50 is configured in the company for the air-breather 40 being connect with shell 10 (referring to Fig.1)
Near the opening 421 of socket part 42.The oil for containing a large amount of bubbles as a result, is readily able to opening from the interconnecting piece 42 of air-breather 40
Mouth 421 flows into air-breathers 40.
As shown in Fig. 3 etc., the seal member well known to O-ring etc. is provided on the end face of the shell 21 of trochoid pump 20
The sealing gland component 25 of composition.Sealing gland component 25 is arranged on the internal rotor 23 in trochoid pump 20 of the shell 21 of trochoid pump 20
With end face in the end face in the axial direction of outer rotor 22, the side opposite with the side for the being provided with wind deflector 50 (shell of Fig. 1
The end face on 21 right side) on.Sealing gland component 25 prevents air (bubble) from being leaked from shell 21 to the direction for leaving air-breather 40,
Thus, it is possible to by Efficient air be oriented to wind deflector 50.
The speed changer structure 1 constituted like that above is acted as described below.
If trochoid pump 20 starts to drive, ATF is inhaled into trochoid pump 20, and is transported to for controlling speed change
Hydraulic control portion.It is accompanied by this, the relative rotation by internal rotor 23 relative to outer rotor 22, ATF mixing airs are from interior turn
It is discharged near the rotary shaft 233 of son 23.
Then, ATF mixing airs flow into the inner space of wind deflector 50 from the one end 51 of wind deflector 50, and in wind-guiding
The other end 52 of wind deflector 50 is flowed in the inner space of plate 50.Also, the other end 52 that the air passes through wind deflector 50
Opening and from the inner space of wind deflector 50 flow out.The opening 421 of the interconnecting piece 42 of air-breather 40 is located at wind deflector 50
Near the opening of the other end 52.Therefore, ATF mixing airs flow into the inside of the interconnecting piece 42 of air-breather 40.
That is, by wind deflector 50, ATF mixing airs are directed to air-breather 40.Also, ventilation chamber 41 inside,
ATF mixing airs are gas-liquid separated into the ATF of air and liquid, and the ATF of liquid is recycled to the inside of shell 10, and air is put
Go out in the air of the outside to ventilation chamber 41.
According to the present embodiment, it can get effect below.
In the present embodiment, speed changer structure 1 has：Air-breather 40 by ventilating chamber 41 taken
It is loaded in the inside of the shell 10 of the speed changer on vehicle and external ventilation；And trochoid pump 20, it is configured in shell 10
It is interior, provide hydraulic oil to the hydraulic control portion for carrying out hydraulic control to speed changer of speed changer.
Trochoid pump 20 has the bubbles oil discharge unit 202 of the oil discharge comprising bubble and will be supplied to hydraulic pressure
The oily discharge unit 201 of the hydraulic oil discharge of control unit.
It includes gas by what is be discharged from bubbles oil discharge unit 202 that the speed changer structure 1, which has wind deflector 50, the wind deflector 50,
Bubble in the oil of bubble is guided to air-breather 40.
Therefore, the ATF mixing airs containing a large amount of bubbles are easy to be directed to air-breather 40, are easy in air-breather 40
By gas-liquid separation.That is, the air for including in ATF mixing airs is improved to the discharge toughness outside shell 10.Therefore, it can inhibit
The bubble in ATF mixing airs containing a large amount of bubbles persistent loop in food tray (not shown).
In addition, venthole oil spout toughness is different according to the operating condition (acceleration and deceleration, turning etc.) of speed changer, however this hair
It is bright also flexibly to cope with these situations.
In addition, trochoid pump 20 have for by hydraulic oil relative to trochoid pump 20 sucking discharge internal rotor, with
And the rotary shaft 233 for making internal rotor rotate, wind deflector 50 has barrel shape, and is configured around rotary shaft 233.Therefore, may be used
The ATF mixing airs flow direction ventilation dress containing a large amount of bubbles for preventing from being discharged from bubbles oil discharge unit 202 by wind deflector 50
Set the direction other than 40.
In addition, pump installation is made of trochoid pump 20.Therefore, it is possible to which ATF mixing airs are easily guided wind deflector 50.
In addition, trochoid pump 20 shell 21 in the end face in the axial direction of internal rotor 23 and outer rotor 22, with
It is provided on the end face of opposite side of the side of wind deflector 50, is provided with for preventing bubble from the shell of trochoid pump 20
The sealing gland component 25 leaked in 21.It is therefore possible to prevent bubble is leaked from the part of the sealing gland component 25 of shell 21, correspondingly make
Bubble is obtained efficiently to be discharged to wind deflector 50.Therefore, it is possible to which efficiently bubble is imported in air-breather 40.
The present invention is not limited to the above embodiments, deformation, improvement in the range of may achieve the purpose of the present invention etc.
Including in the present invention.
For example, the structure in each portion of speed changer structure is not limited to the structure in each portion of the speed changer structure 1 of present embodiment.
For example, wind deflector 50 has cylindrical shape, however it is without being limited thereto.In addition, pump installation is made of trochoid pump 20, however it is not limited to
This.For example, pump installation can also be made of vane pump.
