Description
本發明係有關一種變速裝置，尤其是指一種透過一轉子與一定子在一磁場中作相對運動，或者，透過一低速轉子與一高速轉子在一磁場中作相對運動，其可配合一變速器，來達到調變轉速與輸出扭力的目的，並且，配合一特殊設計之變速盤即可達到多段調變轉速與輸出扭力的目的。 The invention relates to a shifting device, in particular to a relative movement in a magnetic field through a rotor and a stator, or a relative movement in a magnetic field through a low-speed rotor and a high-speed rotor, which can be combined with a transmission. To achieve the purpose of modulation speed and output torque, and with a specially designed shifting disc, it can achieve multi-stage modulation speed and output torque.
基於電動車產業的起飛，電動車動力的部分成為重要的研究領域，而在電動車特別的驅動模式下，提高效率及驅動扭力密度為首要之務。電動馬達需要配合不同的行車扭力需求及行駛速度，為了保持高效率運轉，目前常用的技術為馬達和變速器的搭配，或馬達和減速器的搭配，但是包含機械式變速器，因此增加了重量，另外也有效率、磨損及噪音的問題，利用一般磁性變速器雖然可以減少振動、噪音，但是並不能減少重量。 Based on the take-off of the electric vehicle industry, the part of the electric vehicle power has become an important research field, and in the special driving mode of the electric vehicle, improving the efficiency and driving the torque density is the primary task. Electric motors need to match different driving torque requirements and driving speeds. In order to maintain high efficiency, the current common technology is the combination of motor and transmission, or the combination of motor and reducer, but including mechanical transmission, thus increasing the weight. There are also problems with efficiency, wear and noise. Although the general magnetic transmission can reduce vibration and noise, it does not reduce the weight.
“Test and Simulation of Axial Flux-Motor Characteristics for Hybrid Electric Vehicles”,IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY,VOL.53,NO.3,MAY 2004揭露兩種典型的馬達，如圖一A與圖一B所示。圖一A係為一徑向馬達，其係包括一定子11a以及一動子12a，其中該定子11a與該動子12a之間的磁通 量係沿著與AA軸垂直的徑向方向上。圖一B係為一軸向馬達，其係包括一定子11b以及一動子12b，其中該定子11b與該動子12b之間的磁通量係沿著與BB軸平行的軸向方向上。與徑向馬達比較，軸向馬達的架構適合馬達薄型化，其定子和轉子的位置關係為軸向分佈。薄型馬達可以節省空間，但是馬達本身無法變速，需要外加一變速器以改變其扭力輸出。 "Test and Simulation of Axial Flux-Motor Characteristics for Hybrid Electric Vehicles", IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY, VOL. 53, NO. 3, MAY 2004 discloses two typical motors, as shown in Figures A and B. Figure 1A is a radial motor comprising a stator 11a and a mover 12a, wherein the magnetic flux between the stator 11a and the mover 12a The quantity is along a radial direction perpendicular to the AA axis. Figure 1B is an axial motor comprising a stator 11b and a mover 12b, wherein the magnetic flux between the stator 11b and the mover 12b is along an axial direction parallel to the BB axis. Compared with the radial motor, the structure of the axial motor is suitable for the thinning of the motor, and the positional relationship between the stator and the rotor is axially distributed. A thin motor saves space, but the motor itself cannot be shifted and requires a separate transmission to change its torque output.
“A novel high performance magnetic gear”,IEEE Transactions on Magnetics,2001揭露一種徑向磁性變速器，如圖二所示，其係為該徑向磁性變速器的剖面結構示意圖。該徑向磁性變速器可達5.5：1之變速效果，其係包括：一第一轉子21，其係更包括：一第一軟鐵心211，其係為中空圓柱形；複數個第一磁對212，每一個磁對212更包括：一個永久磁鐵的N極212a；以及一個永久磁鐵的S極212b；一第二轉子22，其係可與該第一轉子21作相對轉動，該第二轉子22更包括：一第二軟鐵心221，其係為中空圓柱形，與該第一軟鐵心211有共同的軸心；複數個第二磁對222，每一個磁對222更包括：一個永久磁鐵的N極222a；以及一個永久磁鐵的S極222b；以及複數個條狀導磁材料23，其係與軸心平行地設置於該第一轉子21與第二轉子22之間。 "A novel high performance magnetic gear", IEEE Transactions on Magnetics, 2001 discloses a radial magnetic transmission, as shown in Figure 2, which is a schematic cross-sectional view of the radial magnetic transmission. The radial magnetic transmission can achieve a shifting effect of 5.5:1, and includes a first rotor 21, which further includes: a first soft iron core 211 which is hollow cylindrical; a plurality of first magnetic pairs 212 Each of the magnetic pairs 212 further includes: an N pole 212a of a permanent magnet; and an S pole 212b of a permanent magnet; and a second rotor 22 that is rotatable relative to the first rotor 21, the second rotor 22 The utility model further comprises: a second soft core 221 which is hollow cylindrical and has a common axis with the first soft core 211; a plurality of second magnetic pairs 222, each of the magnetic pairs 222 further comprises: a permanent magnet An N pole 222a; and an S pole 222b of a permanent magnet; and a plurality of strip magnetic materials 23 are disposed between the first rotor 21 and the second rotor 22 in parallel with the axis.

The second rotor 22 is a low speed rotor. The plurality of strip-shaped magnetic conductive materials 23 are used for magnetic conduction. In this example, a total of 26 strip-shaped magnetic conductive materials 23 are disposed, and any two magnetic conductive materials are separated by an air gap, and the magnetic conductive material is Soft iron core. The interaction between the magnetic field generated by the permanent magnets on one rotor and the strip-shaped magnetically permeable material between the two rotors creates a space harmonic flux that acts as a space for different pole numbers between the gaps. The magnetic flux, in turn, drives the other rotor to rotate, and achieves the purpose of regulating the rotational speed and outputting the torque.

And having a first plane 5111; and a plurality of first magnetic pairs 512, each of the first magnetic pairs 512 The first plane 5111 is fixed to the first conductive material 511 in the radial direction, and each of the first magnetic pairs 512 further includes: an N pole 512a of a permanent magnet; and an S pole 512b of a permanent magnet; The second inductor 52 is a second rotor 52.

Modulate the speed and torque for the purpose.
圖六係為本發明變速裝置之第四實施例的結構側視示意圖。在本實施例中的變速裝置，其係包括：一第一感應子，其係為一定子61，該定子61係為圓環形體並具有一第一平面6111，且至少包括一多相繞線的線圈；一第二感應子，其係為一轉子62，該轉子62係可相對於該定子61作相對轉動，該轉子62更包括：一導磁材料621，其係為圓環形體並具有一第二平面6211，並與該定子61平行設置；以及複數個磁對622，每一個磁對622皆沿著徑向固定於該導磁材料621之該第二平面6211，並且每一個磁對622更包括：一個永久磁鐵的N極622a；以及一個永久磁鐵的S極622b；以及一導磁元件，其係為一變速盤63，該變速盤63 係平行地設置於該定子61與轉子62之間的一圓環形導磁材料，且該變速盤63在沿著徑向的方向上設置有複數個氣隙(與圖五B中的變速盤53具有相同的結構)。 Figure 6 is a side elevational view showing the structure of a fourth embodiment of the shifting device of the present invention. The shifting device in this embodiment includes: a first inductor, which is a stator 61, the stator 61 is a circular body and has a first plane 6111, and includes at least one multi-phase winding a second inductor, which is a rotor 62, the rotor 62 is relatively rotatable relative to the stator 61. The rotor 62 further includes: a magnetically permeable material 621 which is a circular body and has a second plane 6211 disposed parallel to the stator 61; and a plurality of magnetic pairs 622, each of which is radially fixed to the second plane 6211 of the magnetically permeable material 621, and each magnetic pair The 622 further includes: an N pole 622a of a permanent magnet; and an S pole 622b of a permanent magnet; and a magnetic conductive component, which is a shifting disk 63, the shifting disk 63 A circular magnetically permeable material disposed between the stator 61 and the rotor 62 in parallel, and the shifting disk 63 is provided with a plurality of air gaps in a radial direction (with the shifting disk in FIG. 53 has the same structure).
本實施例相當於將上述第三實施例中的其中一個轉子，以定子61取代，將一電能輸入該含有線圈的定子61可以產生和轉子同樣磁對數的空間磁通，並利用多相繞線來得到空間磁通平移的效果，因此可以帶動轉子62作轉動來輸出一機械能，因此達到調變轉速和扭力的目的。 This embodiment is equivalent to replacing one of the rotors in the third embodiment with the stator 61, and inputting a power into the stator 61 containing the coil to generate a spatial magnetic flux of the same magnetic logarithm as the rotor, and using the multiphase winding. In order to obtain the effect of the spatial flux translation, the rotor 62 can be rotated to output a mechanical energy, thereby achieving the purpose of adjusting the rotational speed and the torque.
由式(1)可知，變速比由感應子上的磁極數來決定，並且要二個感應子間的條狀導磁材料數目的配合。當感應子的極數改變時，若能同時配合改變條狀導磁材料的數目(或者氣隙的數目)，則變速比也會改變，例如：假使式(1)中一感應子磁對數p由4變成了8，而另一感應子磁對數不變(即保持22)，如此條狀導磁材料數目需要變成30，帶入公式(1)可以得到新的變速比為8/22=1/2.75(原來是1/5.5)。此即所謂的「多段變速」。 As can be seen from equation (1), the gear ratio is determined by the number of magnetic poles on the inductor, and the number of strip-shaped magnetically permeable materials between the two inductors is matched. When the number of poles of the inductor changes, if the number of strips of magnetically permeable material (or the number of air gaps) can be changed at the same time, the speed ratio will also change, for example, if a sensor magnetic pair p in equation (1) From 4 to 8, and the other sensor has the same magnetic logarithm (ie, 22), so the number of strips of magnetic material needs to be 30, and the formula (1) can be used to obtain a new gear ratio of 8/22=1. /2.75 (originally 1/5.5). This is the so-called "multi-speed shift".
因為轉子上係使用永久磁鐵產生磁極來形成磁對，所以轉子的磁對數不易改變，為了使具有軸向磁通的變速裝置能夠改變變速比，達到多段變速的目的，本發明提出之技術手段為：(1)定子的磁對數可變，以及(2)變速盤的氣隙數目也可變。關於定子的磁對數的改變方法，可參照先前技術等文獻。以下則詳述本發明所提供之氣隙數目可改變之導磁元件：圖七係顯示本發明所提供應用於多段變速裝置之導磁 元件的一實施例結構示意圖。如圖所示，該導磁元件71包含有複數個圓環形導磁材料的變速盤，而且該些變速盤在沿著徑向的方向上設置有不同數目的氣隙。在圖七之導磁元件71只有兩個變速盤，一為第一變速盤711，另一為第二變速盤712，但本發明的導磁元件並不以此為限。其中，該第一變速盤711放射狀排列地設置有24個氣隙7111，該第二變速盤712放射狀排列地設置有32個氣隙7121。 Since the magnetic pole is formed on the rotor by using a permanent magnet to form a magnetic pair, the magnetic logarithm of the rotor is not easily changed. In order to enable the shifting device having the axial magnetic flux to change the speed ratio and achieve the multi-step shifting, the technical means proposed by the present invention is (1) The magnetic logarithm of the stator is variable, and (2) the number of air gaps of the shifting disk is also variable. Regarding the method of changing the magnetic logarithm of the stator, reference may be made to documents such as the prior art.
