M424320 五、新型說明： 【新型所屬之技術領域】 本創作係關於一種電磁煞車結構，尤指一種具備有發 電機之電磁煞車結構。 【先前技術】 習知技術中，應用於車輛煞車系統之結構通常採用來 令片（Brake Pad，又稱煞車皮或煞車片）直接與連接於車輪 轉軸之碟盤或煞車鼓接觸，進而產生摩擦阻力，以使行進 中的車輛停止；然而，車輛煞車之過程中所產生的高摩擦 與高熱將導致來令片的磨損，而使煞車性能隨長期使用下 而逐漸減弱，並且需要定期維修更換，以避免煞車力不足 等危險之情況發生。 因此，電磁式煞車系統係逐漸受到矚目，其係利用電 磁效應於金屬煞車盤上造成渦電流，進而產生相反於電磁 效應產生之磁場的煞車力，而無須採用上述如來令片等構 件，故可避免長期使用下構件因摩擦及高熱導致耗損而需 定期更換等缺點；其中，電磁式煞車系統主要係於車體底 部設置有鋁金屬製成之煞車盤，並由兩側執道所設置之電 磁鐵產生磁場，以使行進之車體的金屬煞車盤切割磁力線 產生磁通量變化，而於金屬煞車盤上形成渦電流與感應磁 場，進而產生煞車力來提供車輛進行減速，因此，電磁式 剎車系統本身係無耗損之缺點，並且，由於電磁式剎車系 統所產生的煞車力係與車輛速度成正比，故當車輛減速時 3 M424320 磁通量變化量亦降低，所產生之煞車力係直接反應車輛之 速度而變化，故無須考量煞車鎖死的問題。 然而，電磁式煞車系統於車輛低速行進時所產生之煞 車力可能不足以達成車輛之減速或停止，故現有之電磁式 煞車系統僅作為輔助煞車的目的，或僅適用於如雲霄飛 車、高速列車等高速運作的交通工具之應用。 【新型内容】 本創作之目的在於提供一種電磁煞車結構，其係具有 於長期使用下無元件耗損之優點；並且，本創作之電磁煞 車結構係可適用於高速與低速之應用；此外，本創作之電 磁煞車結構係具有發電機，而可提供電磁煞車結構中產生 電磁效應所需之供電，並可進一步回饋電磁煞車結構外加 之電瓶之充電電源。 為達上述目的，本創作之一種電磁煞車結構，包含： 一轉軸，固設有一摩擦輪；一發電機，具有一傳動軸及連 接該傳動軸之一傳動件，該傳動件用於接觸該摩擦輪而使 該傳動軸被帶動並發電；一煞車盤組，固設於該轉轴上， 並具有至少一順磁性煞車盤及至少一鐵磁性煞車盤；以及 複數磁軛，係分別設置於各該順磁性煞車盤及各該鐵磁性 煞車盤的兩側，各該磁軛具有至少一激磁線圈，該激磁線 圈係由該發電機及一電瓶的至少其一所供電。 上述之電磁煞車結構，其中該發電機係與該電瓶電性 連接，該發電機所產生之電力係可同時提供該激磁線圈之 4 M424320 供電並作為該電瓶之充電電源。 上述之電磁煞車結構，其中該煞車盤組係且有複數順 磁性煞車盤及複數鐵磁性煞車盤，各各 該鐵磁㈣車錢為㈣地排抑置。 ”、、車盤與各 或二煞車結構’其中該順磁性煞車盤係可由紹 及、電磁煞車結構，其中該鐵雜煞車盤係由鐵 、鋼、&金鋼、#、鎳或其合金所製成。 用下=耗ί創作實施例之電磁煞車結構係可避免長期使 、高用之問題’再者，本創作之電磁煞車結構係可 ==速：低速之煞車應用，且其煞車力可與轉軸速度 _而變化’此外，本創作之電磁煞車結構更且 :=機，而可同時提供電磁煞車效應所需之供電以心 貝電瓶作為充電之電源，而具有省電的優點。 【實施方式】 為充錄解本創作之目的、特徵及功效，兹藉由下述 -體之實施例’並配合所附之圖式，對本創作做—詳 明，說明如後： 請參照第1圖至第3圖，第】圖係為本創作—實施例 Ζ磁煞車結構的示意圖，帛2圖及第3 _分別為本創 一實施例之電磁煞車結構中轉轴、煞車盤组與磁輛的結 構不意圖及部分截面圖。本創作_實施例之電磁 主要包含-轉轴10、一發電機20、一煞車盤組數 M424320 磁軛40，其中，轉軸10係固設有一摩擦輪11 ;發電機20 係具有一傳動軸21及連接傳動軸21之一傳動件22，傳動 件22用於接觸摩擦輪11而使傳動軸21被帶動並發電；煞 車盤組30係固設於轉軸10上，並具有至少一順磁性煞車 盤31及至少一鐵磁性煞車盤32 ;複數磁軛40係分別設置 於順磁性煞車盤31及鐵磁性煞車盤32的兩側，磁軛40中 每一者係具有至少一激磁線圈41，激磁線圈41係由該發電 機20及一電瓶50的至少其一所供電。 於本實施例中，電磁煞車結構1之轉轴10係連接於外 部之轉動機件（圖未示），例如車輪等結構，故轉轴10係與 該轉動機件同步作動，而可藉由轉軸10控制轉動機件之轉 動、加速、減速與停止等運動狀態；其中，轉轴10係固設 有摩擦輪11，摩擦輪11亦隨轉軸10而轉動。 於本實施例中，電磁煞車結構1之發電機20係具有傳 動軸21及連接傳動軸21之傳動件22,傳動件22係可接觸 摩擦輪11而帶動傳動軸21旋轉，而使發電機20產生電力 並輸出；其中，當電磁煞車結構1應用於車輛時，傳動件 22係可連接於車輛之煞車踏板，故使用者欲將車輛減速而 踩踏煞車踏板時，傳動件22係被驅動而接觸至摩擦輪11， 以藉由傳動件22與摩擦輪11之間產生的摩擦力帶動傳動 件22本身與傳動轴21，而使發電機20產生電力輸出。 於本實施例中，電磁煞車結構1之煞車盤組30係以三 個順磁性煞車盤31及二個鐵磁性煞車盤32作為示例，如 圖所示，順磁性煞車盤31及鐵磁性煞車盤32係交替地排 6 M424320 列設置，當順磁性煞車盤31及鐵磁性煞車盤32隨轉軸10 而轉動時，由於在感應磁場下鐵磁性金屬與順磁性金屬所 產生之阻尼效應不同，當轉動中的順磁性金屬於一固定磁 場之下時，所產生的阻尼效應（煞車力）係正比於其轉動速 率，故轉轴10轉動愈快時，順磁性煞車盤31可產生愈大 的煞車力；因此，本實施例之電磁煞車結構1，於低速時以 鐵磁性煞車盤32提供主要之煞車力來源，而於高速時則可 藉由鐵磁性煞車盤32與順磁性煞車盤31同時提供煞車 力，以符合車輛輪胎之高速與低速下的煞車應用，且煞車 力係與車輛速度直接相關聯而具有立即響應之優點。 此外，本實施例之電磁煞車結構1中，順磁性煞車盤 31係由鋁所製成之金屬碟片，鐵磁性煞車盤32係由鐵所製 成之金屬碟片，然係不限於此，順磁性煞車盤31可為其他 順磁性材料（例如：鋁合金）所製成之碟片，鐵磁性煞車盤 32可為其他鐵磁性材料（例如：鋼、合金鋼、姑、鎳或其合 金等）所製成之碟片；並且，煞車盤組30中的順磁性煞車 盤31與鐵磁性煞車盤32之數量係不限於本實施例與圖式 所述，順磁性煞車盤31與鐵磁性煞車盤32之數量愈多， 其煞車效能愈佳。 於本實施例中，電磁煞車結構1係具有複數磁軛40， 其係分別設置於順磁性煞車盤31及鐵磁性煞車盤32的兩 側，即順磁性煞車盤31及鐵磁性煞車盤32之每一者係被 夾設於兩個磁軛40之間；其中，磁軛40之每一者係具有 至少一激磁線圈41，激磁線圈41係由發電機20及外接之 一電瓶50的至少其一所供電，以使通電後之激磁線圈41 產生電磁效應而形成磁場，進而使鐵磁性煞車盤32立刻磁 化而產生阻尼效應，並使順磁性煞車盤31上由於磁通量變 化產生渦電流而形成阻尼效應，以提供減速轉軸10之煞車 力。 於本實施例中，電磁煞車結構1之發電機20另可與電 瓶50電性連接，而可將發電機20所產生之電力的一部分 回饋至電瓶50，用以作為電瓶50充電之電力來源，因此， 當電磁煞車結構1啟動而進行煞車動作時，發電機20開始 作動並產生電力輸出，而可同時提供激磁線圈41以及電瓶 50充電之電力，並且，當轉軸10轉動速度愈快而使傳動件 22帶動傳動軸21之轉動速度愈快，發電機20之發電效率 愈高，則通過激磁線圈41之電流愈大，而使煞車盤組30 所產生之煞車力愈大，進而達成減速之煞車效果；當轉軸 10由於電磁煞車而逐漸減速時，傳動件22帶動傳動軸21 之轉度速度隨轉軸10減低，發電機20所產生之電力亦隨 之減少，則通過激磁線圈41之電流變小，而使煞車盤組30 所產生之煞車力減低；據此，本創作之電磁煞車結構1係 可具有對應轉轴10而直接反應煞車力大小的優點。此外， 當轉軸10於低速下轉動時，激磁線圈41所需之供電電源 係可由電瓶50提供，以避免發電機20產生之電力較低而 不足以提供激磁線圈41足夠的電流。 因此，本創作實施例之電磁煞車結構於於長期使用下 係無習知構件耗損之問題，再者，本創作實施例之電磁煞 f結構係、可適驗高逮與低逮之煞車應用，以 電大小直接關聯而變化’此外，本創作實施例之 更具備發電機，而可同時提供電磁煞車效應 “之供電以及回饋至電瓶作為充電 的優點。 阳/、有名電 是故’本創作在上文中雖已以較佳實施例揭露，然熟 各本項技術者應理解的是，該實施例僅用於描繪本創作， 而=應解讀為限制本創作之範圍。餘t的是，舉凡與該 實鞑例等效之變化與置換，均應設為涵蓋於本創作之範疇 内因此，本創作之保護範圍當以申請專利範圍所界定者 為準。 【圖式簡單說明】 第1圖為本創作一實施例之電磁煞車結構的示意圖。 第2圖為本創作一實施例之電磁煞車結構中轉軸、煞車盤 組與磁軛的結構示意圖 第3圖為本創作一實施例之電磁煞車結構中轉轴、煞車盤 組與磁輛的部分截面圖。 【主要元件符號說明】 1 電磁煞車結構 10 轉軸 摩擦輪 發電機 20 M424320 21 22 30 31 32 40 41 傳動軸 傳動件 煞車盤組 順磁性煞車盤 鐵磁性煞車盤 磁軛 激磁線圈 電瓶 50M424320 V.

[Prior Art] In the prior art, the structure applied to the vehicle brake system usually uses a Brake Pad (also referred to as a brake shoe or a brake shoe) to directly contact the disk or the brake drum connected to the wheel shaft, thereby generating friction.

Change, so there is no need to consider the problem of car lock. However, the braking force generated by the electromagnetic brake system when the vehicle is traveling at a low speed may not be sufficient to achieve the deceleration or stop of the vehicle. Therefore, the existing electromagnetic brake system is only used for the purpose of assisting the brake, or only for the speeding, high-speed train. Applications such as high-speed vehicles. [New content] The purpose of this creation is to provide an electromagnetic brake structure, which has the advantages of no component wear under long-term use; and the electromagnetic brake structure of the present invention can be applied to high speed and low speed applications; The electromagnetic brake structure has a generator, and can provide the power supply required for the electromagnetic effect in the electromagnetic brake structure, and can further feed back the charging power of the battery of the electromagnetic brake structure.

[Embodiment] In order to explain the purpose, features and effects of the creation, the following examples of the body are used, and the accompanying drawings are used to make a detailed description of the creation: Illustrated to Fig. 3, the first diagram is a schematic view of the structure of the Ζ — 帛 帛 帛 帛 帛 帛 帛 帛 帛 帛 帛 帛 及 及 及 煞 煞 煞 煞 煞 煞 煞 煞 煞 煞 磁 磁 磁 磁 磁 磁 磁 磁 磁 磁 磁The structure of the vehicle is not intended and part of the sectional view. The electromagnetics of the present invention mainly include a rotating shaft 10, a generator 20, and a number of brake disc sets M424320 yoke 40, wherein the rotating shaft 10 is fixed with a friction wheel 11; the generator 20 has a transmission shaft 21 And connecting a transmission member 22 of the transmission shaft 21, the transmission member 22 is for contacting the friction wheel 11 to drive and drive the transmission shaft 21; the brake disc assembly 30 is fixed on the rotating shaft 10 and has at least one paramagnetic brake disc 31 and at least one ferromagnetic brake disc 32; the plurality of yokes 40 are respectively disposed on both sides of the paramagnetic brake disc 31 and the ferromagnetic brake disc 32, and each of the yokes 40 has at least one exciting coil 41, the exciting coil 41 is powered by at least one of the generator 20 and a battery 50. In the present embodiment, the rotating shaft 10 of the electromagnetic brake structure 1 is connected to an external rotating member (not shown), such as a wheel structure. Therefore, the rotating shaft 10 is synchronized with the rotating mechanism, and the rotating shaft 10 controls the movement state of the rotating, accelerating, decelerating and stopping of the rotating mechanism; wherein the rotating shaft 10 is fixed with the friction wheel 11, friction The wheel 11 also rotates with the rotating shaft 10. In this embodiment The generator 20 of the electromagnetic brake structure 1 has a transmission shaft 21 and a transmission member 22 connecting the transmission shaft 21, and the transmission member 22 can contact the friction wheel 11 to drive the transmission shaft 21 to rotate, so that the generator 20 generates electric power and outputs Wherein, when the electromagnetic brake structure 1 is applied to a vehicle, the transmission member 22 is connectable to the brake pedal of the vehicle, so when the user wants to decelerate the vehicle and step on the brake pedal, the transmission member 22 is driven to contact the friction wheel 11 In order to drive the transmission member 22 itself and the transmission shaft 21 by the frictional force generated between the transmission member 22 and the friction wheel 11, the generator 20 generates an electric power output. In this embodiment, the brake disc assembly of the electromagnetic brake structure 1 is provided. The 30 series is exemplified by three paramagnetic brake discs 31 and two ferromagnetic brake discs 32. As shown, the paramagnetic brake disc 31 and the ferromagnetic brake disc 32 are alternately arranged in a row of 6 M424320 rows, when paramagnetic brakes are provided. When the disk 31 and the ferromagnetic brake disk 32 rotate with the rotating shaft 10, since the damping effect of the ferromagnetic metal and the paramagnetic metal is different under the induced magnetic field, when the rotating paramagnetic metal is in a fixed magnetic field When the damping effect (twisting force) is proportional to the rotation speed thereof, the faster the rotation of the rotating shaft 10, the greater the braking force can be generated by the paramagnetic brake disk 31; therefore, the electromagnetic brake structure 1 of the present embodiment At low speed, the ferromagnetic brake disc 32 provides the main source of vehicle power, and at high speed, the ferromagnetic brake disc 32 and the paramagnetic brake disc 31 simultaneously provide the braking force to meet the high speed and low speed of the vehicle tire.

In addition, in the electromagnetic brake structure 1 of the present embodiment, the paramagnetic brake disc 31 is a metal disc made of aluminum, and the ferromagnetic brake disc 32 is a metal disc made of iron, but is not limited thereto. The paramagnetic brake disc 31 can be a disc made of other paramagnetic materials (for example, aluminum alloy), and the ferromagnetic brake disc 32 can be other ferromagnetic materials (for example, steel, alloy steel, australis, nickel or alloys thereof, etc.) The disc produced; and the number of the paramagnetic brake disc 31 and the ferromagnetic brake disc 32 in the brake disc group 30 is not limited to that described in the embodiment and the drawings, the paramagnetic brake disc 31 and the ferromagnetic brake The more the number of discs 32, the better the braking performance. In the present embodiment, the electromagnetic brake structure 1 has a plurality of yokes 40 which are respectively disposed on both sides of the paramagnetic brake disc 31 and the ferromagnetic brake disc 32, that is, the paramagnetic brake disc 31 and the ferromagnetic brake disc 32. Each of the yokes 40 is sandwiched between two yokes 40; wherein each of the yokes 40 has at least one excitation coil 41 which is comprised of at least one of the generator 20 and one of the externally connected battery 50 A power supply is provided to cause an electromagnetic effect by the exciting coil 41 after energization to form a magnetic field, thereby causing the ferromagnetic brake disk 32 to be magnetized immediately to generate a damping effect, and to cause eddy current on the paramagnetic brake disk 31 to generate eddy current due to a change in magnetic flux. The effect is to provide the braking force of the deceleration shaft 10. In this embodiment, the generator 20 of the electromagnetic brake structure 1 can be electrically connected to the battery 50, and a part of the power generated by the generator 20 can be fed back to the battery 50 for use as a power source for charging the battery 50. Therefore, when the electromagnetic brake structure 1 is activated to perform the braking action, the generator 20 starts to operate and generates an electric power output, and the excitation coil 41 and the electric power of the battery 50 can be simultaneously supplied, and the rotation speed of the rotating shaft 10 is faster. The faster the rotation speed of the drive shaft 21 is driven, the higher the power generation efficiency of the generator 20 is, the larger the current through the excitation coil 41 is, and the greater the braking force generated by the brake disc group 30 is, thereby achieving the deceleration of the brake. When the rotating shaft 10 is gradually decelerated due to the electromagnetic brake, the transmission speed of the transmission shaft 22 is reduced with the rotation shaft 10, and the electric power generated by the generator 20 is also reduced, and the current passing through the exciting coil 41 is reduced. Therefore, the braking force generated by the brake disc group 30 is reduced; accordingly, the electromagnetic brake structure 1 of the present invention can have the corresponding shaft 10 and directly respond to the magnitude of the braking force. . Further, when the rotary shaft 10 is rotated at a low speed, the power supply required for the exciting coil 41 can be supplied from the battery 50 to prevent the power generated by the generator 20 from being low enough to provide sufficient current for the exciting coil 41. Therefore, the electromagnetic brake structure of the present embodiment has no problem of loss of conventional components under long-term use, and further, the electromagnetic 煞f structure of the present embodiment can be applied to a vehicle with high and low arrest. In addition, the present embodiment has a generator, and can simultaneously provide the electromagnetic bus effect "power supply and feedback to the battery as a charging advantage.
