參閱圖4與圖5,本發明輪速感應裝置3之實施例,安裝於一機車4上,該機車4包含一鎖設有多個螺絲5的後臂41、一樞設於該後臂41的輪軸42、一套置於該輪軸42上的輪圈43,及一設置於該後臂41的後臂軸承44。該後臂41包括一呈環狀並供多個螺絲5鎖設的鎖設部411,及多個自該鎖設部411分別向外延伸的補強肋412, 該等螺絲5是分別對應該等補強肋412的位置而鎖設於該鎖設部411上。該實施例包含:一固定於該輪圈43並能隨該輪圈43轉動的旋動單元31、一圍繞該旋動單元31的外殼單元32,及一安裝於該外殼單元32並朝向該旋動單元31的固測單元33。 Referring to FIG. 4 and FIG. 5, an embodiment of the wheel speed sensing device 3 of the present invention is mounted on a locomotive 4, the locomotive 4 including a rear arm 41 having a plurality of screws 5 locked thereto, and a pivoting arm 41 thereon. The axle 42 is a set of rims 43 disposed on the axle 42 and a rear arm bearing 44 disposed on the rear arm 41. The rear arm 41 includes a locking portion 411 which is annular and is locked by a plurality of screws 5, and a plurality of reinforcing ribs 412 extending outward from the locking portion 411, respectively. The screws 5 are locked to the lock portion 411 corresponding to the positions of the reinforcing ribs 412, respectively. The embodiment includes: a rotating unit 31 fixed to the rim 43 and rotatable with the rim 43 , a housing unit 32 surrounding the rotating unit 31 , and a housing unit 32 mounted to the housing unit 32 The solid measurement unit 33 of the moving unit 31.
參閱圖5與圖6,該外殼單元32包括一圍繞該旋動單元31的殼體321,及一設置於該基板323並套設於該輪軸42的輪速軸承322。該殼體321具有一由該輪軸42所穿設的基板323,及一自該基板323之外周緣彎折延伸,並環繞於該旋動單元31之外周緣的環繞板324。該基板323具有一環設於外周緣的銜接部325,及多個配合鎖設於該後臂41之該等螺絲5的位置,並能分別容置該等螺絲5的凹陷部326。要特別說明的是,由於該外殼單元32之殼體321為一體成型,且以非金屬材質所製成,能快速地利用模具並藉由如射出成型之方式大量製造,且能一次性地同時成型該等凹陷部326,能有效的減少製造成本並縮短製造時間。而在進行該殼體321的射出成型製程時,由於該銜接部325可呈倒角或圓弧角(圖5僅繪示呈倒角的態樣),較易自模具脫模,且因此能提高製造的良率。而若不考慮自模具脫模的因素,亦能單純考慮美觀因素而將該銜接部325設計為階梯狀,且不以上述所載之型態為限。 Referring to FIG. 5 and FIG. 6 , the housing unit 32 includes a housing 321 surrounding the rotating unit 31 , and a wheel speed bearing 322 disposed on the base plate 323 and sleeved on the axle 42 . The housing 321 has a substrate 323 which is bored by the wheel shaft 42 and a surrounding plate 324 which is bent from the outer periphery of the substrate 323 and surrounds the outer periphery of the rotating unit 31. The substrate 323 has a connecting portion 325 disposed on the outer peripheral edge, and a plurality of engaging screws 5 are disposed at positions of the screws 5 of the rear arm 41, and can respectively receive the recessed portions 326 of the screws 5. It should be particularly noted that since the housing 321 of the outer casing unit 32 is integrally formed and made of a non-metal material, the mold can be quickly utilized and mass-produced by, for example, injection molding, and can be simultaneously and simultaneously. Forming the recessed portions 326 can effectively reduce manufacturing costs and shorten manufacturing time. When the injection molding process of the housing 321 is performed, since the engaging portion 325 can be chamfered or arcuate (only FIG. 5 shows a chamfered state), it is easier to demold from the mold, and thus can Improve manufacturing yield. However, if the factor of mold release from the mold is not considered, the joint portion 325 can be designed to be stepped regardless of the aesthetic factors, and is not limited to the type described above.
該固測單元33包括一安裝於該殼體321之基板323上的磁感件331,及一連接於該磁感件331並用以傳輸感應訊號的訊號線332。其中,該殼體321之環繞板324 形成有一供該訊號線332穿設的出線部327。要特別說明的是,在進行組裝時,該出線部327必須以正確的方向組裝,才能使該訊號線332確實連接於一中央控制系統(圖未繪示)。 The self-test unit 33 includes a magnetic sensing member 331 mounted on the substrate 323 of the housing 321 and a signal line 332 connected to the magnetic sensing member 331 for transmitting an inductive signal. Wherein, the surrounding plate 324 of the housing 321 An outlet portion 327 through which the signal line 332 is inserted is formed. It should be particularly noted that, when assembling, the outlet portion 327 must be assembled in the correct direction so that the signal line 332 is indeed connected to a central control system (not shown).
如圖6所示,位於上方的兩個相鄰螺絲5之間的幅角,與其他相鄰螺絲5之間的幅角不同。藉由上述設計,在進行外殼單元32的組裝時,能依據該等螺絲5的位置,分別對應該等凹陷部326之位置,而判斷該外殼單元32的組裝方向,確保該殼體321的出線部327能扣接於正確的位置,避免因誤組而使該訊號線332無法確實連接,進而影響輪速感應之功能。要另行說明的是,所述的凹陷部326及鎖設於該鎖設部411之螺絲5的設計,只要所述之螺絲5設置的位置是與該基板323的凹陷部326相配合,且能藉此判斷該外殼單元32組裝的方向即可。例如亦能僅設置一個凹陷部326,而該鎖設部411僅鎖設一個對應的螺絲5,並配合呈凸出狀的該出線部327而判斷組裝方向,不以如圖4所示的態樣及數目為限。 As shown in Fig. 6, the angle between the two adjacent screws 5 located above is different from the angle between the other adjacent screws 5. With the above design, when the housing unit 32 is assembled, the position of the recessed portion 326 can be determined corresponding to the position of the screw 5, and the assembly direction of the housing unit 32 can be determined to ensure the output of the housing 321 . The wire portion 327 can be fastened to the correct position to prevent the signal line 332 from being reliably connected due to the mis-grouping, thereby affecting the function of the wheel speed sensing. It should be noted that the recessed portion 326 and the screw 5 locked to the locking portion 411 are designed as long as the screw 5 is disposed at a position corresponding to the recessed portion 326 of the substrate 323, and can Thereby, the direction in which the outer casing unit 32 is assembled can be determined. For example, it is also possible to provide only one recessed portion 326, and the locking portion 411 only locks a corresponding screw 5, and cooperates with the protruding portion 327 to determine the assembly direction, not as shown in FIG. The number and number of models are limited.
參閱圖7,該旋動單元31包括一套設於該輪軸42上的套件311、一設置於該套件311上的安裝座312、一安裝於該安裝座312上的磁環313,及一設置於該安裝座312與該環繞板324之間的油封314。當該輪軸42轉動時,該套件311、該安裝座312,及該磁環313皆會隨著轉動,如圖5所示的磁感件331能藉由磁感應原理而感測該磁環313轉動的圈數,並將所感測的圈數資訊經由該訊號線332 傳遞至該中央控制系統,並由一儀表板(圖未繪示)顯示時速資訊。 Referring to FIG. 7 , the rotating unit 31 includes a set 311 disposed on the axle 42 , a mounting seat 312 disposed on the sleeve 311 , a magnetic ring 313 mounted on the mounting base 312 , and a setting An oil seal 314 between the mount 312 and the surrounding plate 324. When the axle 42 rotates, the sleeve 311, the mounting seat 312, and the magnetic ring 313 rotate with each other, and the magnetic sensing member 331 shown in FIG. 5 can sense the rotation of the magnetic ring 313 by the magnetic induction principle. The number of turns and the sensed number of turns information via the signal line 332 Passed to the central control system and displayed by the dashboard (not shown).
如圖7所示,該等螺絲5(由於剖視角度關係,圖7中僅顯示一個)能將該後臂軸承44擋制固定於該後臂41,避免該後臂軸承44自該後臂41脫落而影響該機車4的行駛。其中,配合如圖6所示的螺絲5之型態,該等螺絲5是藉由呈圓形或者六角型的螺帽外端緣來固定該後臂軸承44。每一螺絲5的形態只要能利用其螺帽外端緣來固定該後臂軸承44即可,不以如圖6所示的態樣為限。要特別說明的是,由於本發明是直接利用該等螺絲5固定該後臂軸承44,因此不需對該後臂41進行額外的加工。再者,由於該殼體321之基板323凹設有多個分別用以容置該等螺絲5的凹陷部326,當該外殼單元32配合該後臂41組裝時,該等凹陷部326分別容置該等螺絲5,相較於如圖2所示的擋止凸部122之設計而言,能有效縮短整體的配置寬度。 As shown in FIG. 7, the screws 5 (only one shown in FIG. 7 due to the cross-sectional angle relationship) can fix the rear arm bearing 44 to the rear arm 41, avoiding the rear arm bearing 44 from the rear arm. 41 falls off and affects the travel of the locomotive 4. Wherein, in the form of the screw 5 shown in FIG. 6, the screws 5 are fixed to the rear arm bearing 44 by a circular or hexagonal outer end edge of the nut. The shape of each of the screws 5 is only required to be fixed to the rear arm bearing 44 by the outer edge of the nut, and is not limited to the state shown in FIG. It is to be particularly noted that since the present invention directly fixes the rear arm bearing 44 by means of the screws 5, it is not necessary to perform additional processing on the rear arm 41. Furthermore, since the substrate 323 of the housing 321 is recessed with a plurality of recesses 326 for accommodating the screws 5, when the housing unit 32 is assembled with the rear arm 41, the recesses 326 are respectively accommodated. By arranging the screws 5, the overall arrangement width can be effectively shortened compared to the design of the stopper projections 122 as shown in FIG.
綜上所述,該殼體321之基板323形成有至少一個凹陷部326,能配合容置鎖設於該後臂41的螺絲5,藉此能在不對該後臂41進行額外加工的情況下,達成縮短整體配置寬度的效果,並能藉由彼此位置相對應的凹陷部326以及螺絲5,確認該外殼單元32組裝的方向性,避免發生誤組的情況,故確實能達成本發明之目的。 In summary, the substrate 323 of the housing 321 is formed with at least one recessed portion 326, which can fit and receive the screw 5 locked to the rear arm 41, thereby enabling the additional processing of the rear arm 41 without additional processing. The effect of shortening the overall arrangement width is achieved, and the directionality of the assembly of the outer casing unit 32 can be confirmed by the recessed portion 326 and the screw 5 corresponding to each other, thereby avoiding the occurrence of a mis-group, and thus the object of the present invention can be achieved. .
