The illustrative embodiments of the present invention are described with reference to the accompanying drawings.
First embodiment
Reference picture 3-5, first embodiment of the invention are related to a kind of rolling stock including two rotors and sent out with disc type
Motor.
The rolling stock of first embodiment includes the first rotor 2, the rotor 4 of stator 3 and second with disk generator.First
Rotor 2, the rotor 4 of stator 3 and second are discoid or circular (being " plate-like " alleged by the present invention).Stator 3 is located at first
Between the rotor 4 of rotor 2 and second, the distance between rotor 4 of the first rotor 2 and second is air gap.The first rotor 2, stator 3 and
Two rotors 4 are parallel to each other so that the main surface (card) of three is relative to each other.
Shaft end of the first rotor 2 directly with the axletree 1 of rolling stock is connected, and stator 3 is fixed to unshowned railway
On the firmware of vehicle, described firmware refers to do not rotated with the axletree and relatively-stationary part of railway vehicle body in the application,
Such as end cap of axle box, axle box framework or axle box, so as to based on stator 3 and rotor (rotor 4 of the first rotor 2 and second)
Fixed position relation, kinetic energy when rolling stock axletree is rotated are converted into electric energy.Formed with hole 31, the second rotor 4 in stator 3
The first rotor 2 and/or axletree 1 are fixed on by the bolt 5 through the hole 31.So that 2 and second rotor of the first rotor 4 is synchronous
Rotate.
Permanent magnet is installed to the outer surface (card) of rotor, in Fig. 4, illustrate only the first rotor 2 and permanent magnetism thereon
Body 21.It should be appreciated that at least in terms of permanent magnet, the second rotor 4 has the structure similar with the first rotor 2, the He of the first rotor 2
The permanent magnet of second rotor 4 is respectively opposite each other, and the magnetic pole of the permanent magnet of relative position is opposite on circumference.So as to from the first rotor
The magnetic line of force that 2 permanent magnet comes out reaches another permanent magnet of the second rotor 4 through stator 3, and vice versa.
Compared with the magnet exciting coil (electromagnet) of the rotor of the generator of general barrel-shaped structure, generated electricity in the disc type of the present invention
Kinetic energy of the machine based on rolling stock, with reference to permanent magnet is used in rotor, this make it that the construction of whole generator is more simple, more suitable
For rolling stock, in addition, the disk generator of the present invention need not carry out larger change to existing rolling stock, it is only necessary to will
Disk generator is installed to the bogie or walking frame of rolling stock.
In order to further mitigate the thickness of rotor (axial width) and quality, can construction rotor material in formed with
By the permanent magnetism shape identical through hole or blind hole of installation, then by permanent magnet be embedded into and/or be adhered to formed through hole or
In blind hole.
Stator 3 includes stator coil (not shown).Stator 3 can at its center or outer peripheral edge is installed on axle box (not shown)
Framework or other firmwares.
In the Double-rotor disc generator of the present invention, the combining structure with single rotor described later and yoke/backboard
Compare, magnetic field intensity is bigger, can produce bigger generator output.
Second embodiment
Illustrate second embodiment of the present invention referring to Fig. 6.For being marked with first embodiment identical part
Identical reference, and omit and these parts are illustrated.
Second embodiment of the present invention is related to a kind of rolling stock including a rotor and a yoke and sent out with disc type
Motor.
Reference picture 6, the rolling stock of second embodiment include the first rotor 2, stator 3 and yoke 6 with disk generator.
The first rotor 2, stator 3 and yoke 6 are discoid.Stator 3 is between the first rotor 2 and yoke 6, yoke 6 and first turn
It is air gap between son 2.The first rotor 2, stator 3 and yoke 6 are parallel to each other so that the main surface (card) of three phase each other
It is right.
The size of the air gap should rationally be set according to practical application request, and usually, air gap is bigger, and generating efficiency is lower.
The first rotor 2 to be mounted directly to the shaft end of axletree 1, it is preferable that the first rotor 2 utilizes the shaft end of in general axletree 1
Existing screw be installed to the shaft end of axletree 1.So, the change to existing axletree 1 is farthest reduced.Stator 3
Axle box framework 7 is fixed to yoke 6.Stator 3 and yoke 6 can be respectively fixed to axle box framework 7.It is, however, preferable that stator 3
Axle box framework 7 is fixed to together with yoke 6.
In the example depicted in fig. 6, for example, by bolt, riveting, welding or any other be fixedly connected with means by stator 3
It is fixed to the end cap 71 of axle box 7 together with yoke 6.So, very simple, conveniently is installed.
Yoke 6 provides passage for the magnetic line of force of the permanent magnet of the first rotor 2.It is, the permanent magnet on the first rotor 2
The magnetic line of force through stator 3 reach yoke 6, then from yoke 6 return the first rotor 2 on permanent magnet.With only setting one to turn
Son is compared, and the setting of yoke 6 enhances the output of generator.
In second embodiment, there is no strict requirements to the relative position relation between the first rotor 2 and yoke 6, with
The Double-rotor disc generator of first embodiment is compared, in this second embodiment need not be as in first embodiment
It is accurately aligned with the rotor 4 of the first rotor 2 and second.In the first embodiment, stator 3 is being installed to end as shown in Figure 6
, it is necessary to enter eleven punch 11 to the second rotor 4 in the case of lid 71；In the case of realizing that stator 3 is fixed in the outer peripheral edge of stator 3,
Corresponding fixed connection structure is needed, thus needs larger installing space.In this second embodiment, stator 3 (and yoke 6)
Installation it is more simple, the space of occupancy is smaller, while the effective usable floor area that can improve stator and rotor (arranges permanent magnetism
The area at the position of body or coil).Equally, the dismounting of the generator of second embodiment is also more simple and convenient.
In the present invention, it is preferred to axle box framework 7 is partly or entirely made of cast iron.Compared with aluminium casing, cast iron
Cost is lower, and has excellent explosion-proof.
Compared with the generator of barrel-shaped structure, disk generator of the invention has at least following advantage.
(1) due to rotor and stator, card is relative in parallel with each other, thus the alignment demand between rotor and stator is very
It is low.So as to reduce generator size.
(2) disk generator easily is dismantled from bogie, because being between the stator and rotor of disk generator
Face attracts, therefore the magnetic force between rotor and stator is small.
(3) disk generator can produce electric power at the low rotational speed, and the initial torque between stator and rotor is than tubular structure
Initial torque between the rotor and stator of the generator made is much lower, is more suitable for being applied to rolling stock.
(4) rotor and stator can be with relatively thin, thus rotor and stator quality are relatively low, are convenient for disk generator and are installed
The dynamic equilibrium process of the axletree arrived.
Certainly, under the teachings of the present invention can be to this invention is not restricted to above-mentioned embodiment, those skilled in the art
The above-mentioned embodiment of invention is variously modified and modification, without departing from the scope of the present invention.
For example, the number of the rotor, stator in the application, rotor to axletree and stator to axle box framework mounting means not
It is limited to above-mentioned embodiment, bolt, the set location of permanent magnet, number can also suitably be set.
For example, the first rotor can also be fixed to shaft end by the other structures of buckle etc..
