In this kind of sun and planet gear 6, sun gear 21 rotates in the lump with rotor 14, and surrounding's planetary wheel 23 revolution in sun gear 21, rotate with this wheel hub 4, and the rotation of rotor 14 is conveyed to wheel hub 4 after slowing down.And, because sun and planet gear 6 is for partially flat, so can configure to block the mode of peristome 10a, contribute to the slimming of wheel hub 4.
The wheel hub 4 of drum type consists of the 4A of hub body portion of cup-shaped shape and the partially flat cap 4B that the open end 4a of the 4A of hub body portion is sealed.Under the state docking with the flange portion 4b that is formed at cap 4B in the flange portion 4e that makes to be formed at the 4A of hub body portion, by screw rod 28, the 4A of hub body portion and cap 4B is integrated.And, in the intersection of the 4A of hub body portion and cap 4B, be situated between the caulking gum 29 of ring-type is housed.
And then, in axis L direction, at the outstanding hole 4c of axletree that is formed at the end of the 4A of hub body portion, the clutch shaft bearing portion 30 consisting of antifriction-bearing box in order to the rotation with respect to axletree 2 of supporting wheel hub 4 is installed, the outstanding hole 4d of axletree being formed at the end of cap 4B, is provided with the second bearing portion 31 consisting of antifriction-bearing box in order to the rotation with respect to axletree 2 of supporting wheel hub 4.And, in an end of axletree 2, be screwed the first nut portion 32 that keeps clutch shaft bearing portion 30, the foreign steamer 30a of clutch shaft bearing portion 30 is connected to the 4A of hub body portion of wheel hub 4, the interior 30b of wheel of clutch shaft bearing portion 30 is connected to the first nut portion 32, with this, prevents coming off of clutch shaft bearing portion 30.Similarly, in the other end of axletree 2, the foreign steamer 31a that is screwed the second nut portion 33, the second bearing portions 31 that keep the second bearing portion 31 is connected to the cap 4B of wheel hub 4, the interior 31b of wheel of the second bearing portion 31 is connected to the second nut portion 33, with this, prevents coming off of the second bearing portion 31.
In the space that the end wall 10c by cap 4B, motor shell 10 and the second bearing portion 31 delimited, dispose discoideus circuit substrate 7, the circuit substrate 7 that electronic component is housed has by utilization the second M2 of resin die portion that the resin of electric insulating quality and elastic force forms and seals.The cap 4B of this second resin die M2 of portion and rotatable wheel hub 4 separates, and the end face M2a of the second M2 of resin die portion connects airtight in the outside wall surface of the end wall 10c of motor shell 10.And then, in the central opening 7a of circuit substrate 7 and the central opening M2c of the second M2 of resin die portion, be inserted with end wall 10c from motor shell 10 along axletree 2 and outstanding columned jut 10d, circuit substrate 7 is close to the end wall 10c of motor shell 10 and configuration abreast.And, the distribution 34 that line is connected in circuit substrate 7 connects the interior 31b of wheel of the second bearing portions 31 and is expelled to outside, and the distribution that is formed at the interior 31b of wheel of the second bearing portion 31 is extracted out and in hole 35, is filled with by being the leakproofing material 39 of the water-proofness that forms of identical material with the M1 of first and second resin die portion, M2.
The foreign steamer 31a of the second bearing portion 31 is fixed on wheel hub 4, inside take turns 31b and be fixed on axletree 2, and rotate supporting wheel hub 4 freely, long-pending the forming than the footpath directional profile of the jut 10d of motor shell 10 of footpath directional profile of this interior 31b of wheel amassed greatly, and by nut portion 33 end face 10e crimping towards jut 10d from axis L direction.Moreover, also can be in inserting other members between foreign steamer 31a and wheel hub 4 or between the interior 31b of wheel and axletree 2, but when this situation, these stop is essential.Again, the circumference M2b of the second M2 of resin die portion protrudes annularly in axis L direction, realizes the amplification of the second M2 of resin die portion, and realize the lifting of the heat radiation of electronic component with this.
In this electric hub unit 1, the first M1 of resin die portion and core 11 are crimped on the periphery wall 10b of motor shell 10, by the first M1 of resin die portion and the second M2 of resin die portion, sandwiched the end wall 10c of motor shell 10, the wall M2d that forms the central opening M2c of the second M2 of resin die portion is crimped on the side face of jut 10d, therefore the heat producing in stator 13 is conveyed to motor shell 10 via the first M1 of resin die portion, and the heat that the electronic component on circuit substrate 7 produces is conveyed to motor shell 10 via the 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 hub unit 1 of this kind of formation easily makes the second bearing portion 31 maximize, and even if motor shell 10 (motor 3) and circuit substrate 7 are completely by wheel hub 4 raising that also can realize heat radiation of surrounding, and, the second bearing portion 31 is more maximized, more can improve radiating effect.
The second bearing portion 31 keeps precision and endurance ability in order to improve rotation, in design aspect, be forced to the maximization that need to make, if but adopt as the formation as the present invention, can realize the raising of radiating effect and the rotational stabilization of wheel hub 4 by the maximization of the second bearing portion 31 simultaneously.And then, if generally speaking improve the resistance to effect of heat of electronic component, can cause electronic component self to maximize, but in the present invention, because improving the thermal diffusivity of the electronic component on circuit substrate 7, even if so do not use electronic component that resistance to effect of heat is higher also can, can realize miniaturization and the cost degradation of electronic component, its result, can realize the spacial downsizing of electronic component, and the spacial amplificationization that can realize motor part 3 increases to the maximization of the motor part 3 of object with power.
Again, wheel hub in common electric hub unit, during most situation, be that the mode that wraps into motor part and reducing gear portion forms, therefore and be rotated, though in the extraction mode of distribution in the past, have to be designed to make axletree to connect, but when situation of the present invention, the distribution 34 that can utilize the interior 31b of wheel of the second bearing portion 31 of maximization easily line to be connected in to circuit substrate 7 is expelled to outside, and the second bearing portion 31 more maximizes, and the extraction of distribution 34 is easier.Moreover this distribution 34 is extracted hole 35 by being formed at the slit 10f of jut 10d out from distribution and is exported to outside.
And then, in this electric hub unit 1, so that the mode that the rotor 14 in sun and planet gear (reducing gear portion) 6 and motor part 3 and stator 13 separate, discoideus dividing plate 36 with respect to axis L arranged perpendicular is disposed in 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 is close to 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, reducing gear portion 6 is separated with rotor 14 and stator 13 in motor part 3, and by motor shell 10, reducing gear portion 6 is separated with circuit substrate 7.Again, because disposing reducing gear portion 6 in the peristome 10a in motor shell 10, 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 motor shell 10, result, reducing gear portion 6 approaches with rotor 14 and stator 13 in motor part 3, rotor 14 and stator 13 are easily subject to the impact of the abrasive power of gear 21,22,23, even if but the abrasive power of the gear 21,22,23 producing in reducing gear portion 6 disperses in the lump with the lubricant of coating reducing gear portion 6, by dividing plate 36, abrasive power is also 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 being disposed in 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, the heat being produced by coil 12 is difficult to be conveyed to circuit substrate 7 by motor shell 10, can prevent the life-span minimizing of the electronic component on circuit substrate 7 or the mistake start of electronic component.
And, by effectively utilizing the axial region 26 of the rotation of support planetary gears 23, can utilize screw rod 37 to make dividing plate 36 fixing simply.And if dividing plate 36 is fixed on to wheel hub 4,, when motor part 3 being installed on to wheel hub 4 when interior, planetary wheel 23 can not fall, thereby the workability while motor part 3 being assembled in the hub body 4A of wheel hub 4 can become good.When the decomposition cleaning of the inside of electric hub unit 1, by the employing of screw rod 37, can easily dividing plate 36 be unloaded again.Moreover dividing plate 36 also can be fixed on by welding or ca(u)lk etc. the free end of axial region 26.
The present invention is not limited to above-mentioned example.For example, as shown in Figure 4, in other electric hub units 1A, in the back side of circuit substrate 7, (face of opposition side of the face of electronic component is housed), be crimped with the heating panel 25 of the ring-type being formed 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 thermal capacitance that the electronic component on circuit substrate 7 produces easily be conveyed to the end wall 10c of motor shell 10.
