The wheel speed sensor is arranged with a slight gap relative to the sensor ring. The sensor ring is provided with a detection hole for speed detection covering the entire circumference, and rotates integrally with the wheel.

車輪轉速感應器具有永久磁鐵及線圈等，且相對於感應器環產生磁力線。磁力線當藉由感應器環的旋轉而檢測孔通過車輪轉速感應器前時，磁通密度會週期性變化。車輪轉速感應器會將藉由磁通密度變化而流動於線圈的交流電流輸出作為表示車輪轉速的訊號。 [先前技術文獻] [專利文獻]The wheel rotational speed sensor has permanent magnets, coils, etc., and generates magnetic lines of force with respect to the sensor ring. The magnetic flux density changes periodically when the detection hole passes in front of the wheel speed sensor by the rotation of the sensor ring. The wheel speed sensor outputs the alternating current flowing through the coil due to the change of the magnetic flux density as a signal representing the wheel speed.

In one example, as shown in FIG. 2 , the wheel rotational speed sensor 54 is attached to the front brake device 42A. Hereinafter, the wheel rotational speed sensor 54 attached to the front brake device 42A will be described. The wheel rotational speed sensor 54 may also be attached to the rear brake device 42B. The sensor bracket 56 is fixed to the front brake device 42A. The housing 60 is attached to the front brake device 42A.

感應器58，固定成相對於感應器支架56可朝與車輪14的輪轂軸的軸方向平行的方向移動。在一個例子，感應器58，固定成可朝與前輪14A的輪轂軸的軸方向A1平行的方向A2移動。具體來說，感應器支架56，具有在與軸方向A1平行的方向貫穿的貫穿孔62。感應器58插入於貫穿孔62而被固定。感應器58固定成相對於前煞車碟片44A隔著預定的間隙。The sensor 58 is fixed so as to be movable relative to the sensor holder 56 in a direction parallel to the axial direction of the hub axis of the wheel 14 . In one example, the sensor 58 is fixed so as to be movable in the direction A2 parallel to the axial direction A1 of the hub axle of the front wheel 14A. Specifically, the sensor holder 56 has a through hole 62 penetrating in a direction parallel to the axial direction A1. The inductor 58 is inserted into the through hole 62 and fixed. The sensor 58 is fixed with a predetermined gap with respect to the front brake rotor 44A.

前煞車碟片44A包含感應器環64。感應器環64只要是與前輪14A為一體而旋轉的構造即可，也可與前煞車碟片44A設置為不同個體。感應器環64具有速度檢測用檢測孔66。複數的檢測孔66設置涵蓋感應器環64的整個圓周。感應器58設置成讓與軸方向A1平行的方向的其中一方的端面面對感應器環64。The front brake rotor 44A includes a sensor ring 64 . The sensor ring 64 only needs to be a structure that rotates integrally with the front wheel 14A, and may be provided separately from the front brake disc 44A.

The inductor 58 is provided so that one end face in the direction parallel to the axial direction A1 faces the inductor ring 64 .

感應器58在內部具有永久磁鐵及線圈等。感應器58藉由檢測與前輪14A為一體而旋轉的感應器環64的轉速，來檢測出前輪14A的轉速。具體來說，感應器58藉由永久磁鐵產生磁力線。藉由感應器環64的旋轉而每當檢測孔66通過感應器58前時，磁力線的磁通密度會週期性變化。與磁通密度變化的週期對應的頻率的交流訊號流動於感應器58的線圈。交流訊號的頻率與感應器環64的轉速成比例。感應器58，將流動於線圈的交流訊號對ABS控制裝置輸出作為表示前輪14A的轉速的訊號。The inductor 58 has a permanent magnet, a coil, and the like inside. The sensor 58 detects the rotational speed of the front wheel 14A by detecting the rotational speed of the sensor ring 64 that rotates integrally with the front wheel 14A. Specifically, the inductor 58 generates magnetic field lines by means of permanent magnets. Due to the rotation of the inductor ring 64 , the magnetic flux density of the magnetic field line changes periodically whenever the detection hole 66 passes through the inductor 58 . An AC signal of a frequency corresponding to the period of the change in the magnetic flux density flows through the coil of the inductor 58 . The frequency of the AC signal is proportional to the rotational speed of the sensor ring 64 . The sensor 58 outputs the AC signal flowing through the coil to the ABS control device as a signal indicating the rotational speed of the front wheel 14A.

感應器58，由於各零件的形狀誤差等原因而其與感應器環64的間隔不是預定間隔的話，前輪14A的轉速的檢測精度會降低。因此藉由讓感應器58朝與軸方向A1平行的方向A2移動，而將其與感應器環64的間隔調整成預定的間隔。If the distance between the sensor 58 and the sensor ring 64 is not a predetermined distance due to a shape error of each component or the like, the detection accuracy of the rotational speed of the front wheel 14A is lowered. Therefore, by moving the sensor 58 in the direction A2 parallel to the axial direction A1, the distance between the sensor ring 64 and the sensor ring 64 is adjusted to a predetermined distance.

The sensor 58 is fixed to the sensor holder 56 by the sensor fixing member 72 inserted into the long hole 74 . By releasing the screwing of the sensor fixing member 72 , the position of the sensor 58 can be adjusted relative to the sensor bracket 56 within the predetermined range D1 . In the wheel rotational speed sensor 54 , the wall portions at both ends of the long hole 74 in the direction parallel to the axial direction A1 and the screw head portion of the sensor fixing member 72 serve as the restriction mechanism 70 .

車輪轉速感應器54，在安裝於前叉30的情況，首先藉由煞車固定構件68將感應器支架56固定於前煞車裝置42A。接著將感應器58插入於感應器支架56的貫穿孔62。感應器58，從貫穿孔62的面向感應器環64側的相反側插入。之後在將感應器58定位成與感應器環64的間隔成為預定間隔之後，將感應器固定構件72插入感應器支架56的長孔，藉由感應器固定構件72固定於感應器支架56。When the wheel rotational speed sensor 54 is attached to the front fork 30 , first, the sensor bracket 56 is fixed to the front brake device 42A by the brake fixing member 68 . Next, the sensor 58 is inserted into the through hole 62 of the sensor holder 56 . The inductor 58 is inserted from the side opposite to the side facing the inductor ring 64 of the through hole 62 . After the sensor 58 is positioned at a predetermined distance from the sensor ring 64 , the sensor fixing member 72 is inserted into the long hole of the sensor holder 56 and fixed to the sensor holder 56 by the sensor fixing member 72 .

如第5圖所示，為了將感應器58定位，而使用車輪轉速感應器用夾具76。夾具76具有插入部78，插入部78用來插入於：與人力驅動車10的車輪14為一體而旋轉的感應器環64與車輪轉速感應器54之間；夾具76，用來限定：可調整相對於感應器環64的位置的車輪轉速感應器54、與感應器環64的間隔。夾具76，在插入部78插入於感應器環64與車輪轉速感應器54之間的狀況，從與軸方向A1平行的方向觀察插入部78，插入部78設置成與感應器環64的檢測孔66至少局部重複。感應器58，在其面向感應器環64側的端面抵接於夾具76的插入部78的位置，藉由感應器固定構件72固定於感應器支架56。As shown in FIG. 5, in order to position the sensor 58, the jig 76 for wheel rotation speed sensors is used.

Slot 80 has a width equal to the thickness of inductor ring 64 . Thereby, the jig 76 is used to prevent displacement in the axial direction A1 when the insertion portion 78 is inserted between the sensor ring 64 and the wheel rotational speed sensor 54 .

夾具76，在與車輪14的輪轂軸的軸方向平行的方向具有第1軸方向長度，插入部78在與軸方向平行的方向具有第2軸方向長度；第1軸方向長度較上述第2軸方向長度的兩倍更大。在一個例子，如第6圖所示，夾具76，在與軸方向A1平行的方向具有第1軸方向長度L1，插入部78在與軸方向A1平行的方向具有第2軸方向長度L2。第2軸方向長度L2，與預定的感應器58與感應器環64的間隔相等。由於第1軸方向長度L1較第2軸方向長度L2的2倍更大，所以可提升夾具76的握持性。The clamp 76 has a first axial length in a direction parallel to the axial direction of the hub shaft of the wheel 14, and the insertion portion 78 has a second axial length in a direction parallel to the axial direction; the first axial length is longer than the above-mentioned second axial length Twice the direction length is greater. In one example, as shown in FIG. 6 , the jig 76 has a first axial length L1 in a direction parallel to the axial direction A1, and the insertion portion 78 has a second axial length L2 in a direction parallel to the axial direction A1. The second axial length L2 is equal to the predetermined interval between the sensor 58 and the sensor ring 64 . Since the first axial length L1 is larger than twice the second axial length L2, the grip of the jig 76 can be improved.

夾具76，在外表面具有非平滑部，非平滑部包含凹部及凸部的至少其中一方。非平滑部是用來在握持夾具76的狀態止滑。在一個例子，如第7圖所示，非平滑部，為朝與軸方向A1平行的方向延伸的夾具貫穿孔82。藉此，夾具76，為簡易的構造且可防止握持狀態的滑動。The jig 76 has a non-smooth portion on the outer surface, and the non-smooth portion includes at least one of a concave portion and a convex portion. The non-smooth portion is for preventing slippage in a state in which the jig 76 is held. In one example, as shown in FIG. 7 , the non-smooth portion is a clip through hole 82 extending in a direction parallel to the axial direction A1. Thereby, the clip 76 has a simple structure and can prevent slippage in the gripped state.
