The foreign steamer 31a of the second bearing portion 31 is fixed in wheel hub 4, interior wheel 31b is fixed in axletree 2, and rotate supporting wheel hub 4 freely, should in the footpath directional profile of wheel 31b long-pending form long-pending bigger than the footpath directional profile of the jut 10d of motor shell 10, and by nut portion 33 end face 10e crimping towards jut 10d from axis L direction.Moreover, also can between foreign steamer 31a and the wheel hub 4 or interior take turns between 31b and the axletree 2 insert other members, but when this situation, these stop is essential.Again, the circumference M2b of second M2 of resin die portion protrudes on axis L direction annularly, realizes the amplificationization of second M2 of resin die portion with this, and realizes the lifting of the heat radiationization of electronic component.
In this electric wheel hub unit 1, first M1 of resin die portion and core 11 are crimped on the periphery wall 10b of motor shell 10, sandwich the end wall 10c of motor shell 10 by first M1 of resin die portion and second M2 of resin die portion, the wall M2d that forms the central opening M2c of second M2 of resin die portion is crimped on the side face of jut 10d, therefore the heat that is produced in the stator 13 is conveyed to motor shell 10 via first M1 of resin die portion, and the heat that the electronic component on the circuit substrate 7 produced is conveyed to motor shell 10 via second M2 of resin die portion.And the heat that concentrates on motor shell 10 can be to outside bulk storage after being conveyed to the interior 31b of wheel of the second bearing portion 31.The electric wheel hub unit 1 of this kind formation makes the second bearing portion 31 maximize easily, even and if motor shell 10 (motor 3) and circuit substrate 7 are surrounded by wheel hub 4 fully and also can realize that heat-dissipation improves, and, the second bearing portion 31 is maximized more, then can improve radiating effect more.
The second bearing portion 31 keeps precision and endurance ability in order to improve rotation, be forced to the maximization that need make in design aspect, but, then can realize the raising of radiating effect and the rotational stabilization of wheel hub 4 simultaneously by the maximization of the second bearing portion 31 if adopt as the formation as the present invention.And then, generally speaking then can cause electronic component self to maximize if improve the resistance to effect of heat of electronic component, but in the present invention, because of improving the thermal diffusivity of the electronic component on the circuit substrate 7, even if so do not use the higher electronic component of resistance to effect of heat also can, can realize the miniaturization and the cost degradation of electronic component, its result, can realize the spacial downsizing of electronic component, and can realize that the spacial amplificationization of motor part 3 promptly increases to the maximization of the motor part 3 of purpose with power.
Again, wheel hub in the common electric wheel hub unit, be to form during situation mostly in the mode that wraps into motor part and reducing gear portion, therefore and be rotated, though in the extraction mode of in the past distribution, have to be designed to make axletree to connect, but when situation of the present invention, can utilize the interior 31b of wheel of the second bearing portion 31 of maximization easily wire joint to be expelled to the outside in the distribution 34 of circuit substrate 7, the second bearing portion 31 maximizes more, and then the extraction of distribution 34 is easy more.Moreover this distribution 34 is extracted hole 35 by the slit 10f that is formed at jut 10d out from distribution and is exported to the outside.
And then, in this electric wheel hub unit 1, so that the mode that rotor 14 in sun and planet gear (reducing gear portion) 6 and the motor part 3 and stator 13 separate, discoideus dividing plate 36 with respect to axis L arranged perpendicular is disposed in the motor shell 10 as another part, this dividing plate 36 is connected to the free end of the axial region 26 of support planetary gears 23, and fixes by being screwed in the screw rod 37 of the internal thread part 26a of axial region 26.The outer circumference end of dividing plate 36 approaches the periphery wall 10b of motor shell 10, and axletree 2 runs through the 36a of central opening portion of dividing plate 36, and makes sun gear 21 outstanding from the 36a of central opening portion.Again, screw rod 37 is for locking and be inserted into dividing plate 36 across packing ring 38.
By this dividing plate 36, rotor 14 and stator 13 in reducing gear portion 6 and the motor part 3 are separated, and reducing gear portion 6 is separated with circuit substrate 7 by motor shell 10.Again, because of in the peristome 10a of motor shell 10, disposing reducing gear portion 6, so can be about wheel hub 4, shortening axis L direction is the length of vehicle-width direction, thereby can make wheel hub 4 slimmings.
In order to reach this slimming, reducing gear portion 6 is disposed in the motor shell 10, the result, reducing gear portion 6 is approaching with rotor 14 and stator 13 in the motor part 3, rotor 14 and stator 13 are subjected to the influence of the abrasive power of gear 21,22,23 easily, even if but the abrasive power of the gear 21,22,23 that is produced in the reducing gear portion 6 disperses in the lump with the lubricant of coating reducing gear portion 6, by dividing plate 36, abrasive power also is difficult to be attached to rotor 14 and stator 13, can avoid the malrotation because of the caused motor part 3 of snapping in of abrasive power.And then circuit substrate 7 is away from the reducing gear portion 6 that is disposed in the motor shell 10, and be disposed at motor shell 10 outside, thereby the abrasive power of gear 21,22,23 extremely difficulty adhere to.And circuit substrate 7 separates with coil 12 by motor shell 10, is difficult to be conveyed to circuit substrate 7 by over-all heat transfer motor shell 10 that coil 12 produced, and the life-span that can prevent the electronic component on the circuit substrate 7 reduces or the mistake start of electronic component.
And the axial region 26 of the rotation by effectively utilizing support planetary gears 23 can utilize screw rod 37 to make dividing plate 36 fixing simply.And if dividing plate 36 is fixed in wheel hub 4, then when being installed on motor part 3 in the wheel hub 4, planetary wheel 23 can not fall, thereby the operation when motor part 3 being assembled in the hub body 4A of wheel hub 4 can become good.When the in-to-in in electric wheel hub unit 1 decomposes cleaning, can easily dividing plate 36 be unloaded by the employing of screw rod 37 again.Moreover dividing plate 36 also can be fixed in the free end of axial region 26 by welding or ca(u)lk etc.
The present invention we can say and is not limited to above-mentioned example.For example, as shown in Figure 4, in other electric wheel hub unit 1A, (face of opposition side of the face of electronic component is housed) in the back side of circuit substrate 7, be crimped with the heating panel 25 of the ring-type that constitutes by non-conductive metals such as aluminium, and this heating panel 25 is crimped on the outside wall surface of the end wall 10c of motor shell 10.By the employing of this heating panel 25, make the thermal capacitance that electronic component produced on the circuit substrate 7 easily be conveyed to the end wall 10c of motor shell 10.
