이 고안은 크랭크축에 동기하여 회전하는 구동축에 베인이 고착된 내연기관 점화용 배전기에 관한 것이다.This invention relates to an internal combustion engine ignition distributor in which vanes are fixed to a drive shaft rotating in synchronization with a crankshaft.
제4도는 종래의 내연기관용 점화용 배전기의 일예의 단면도, 제5도는 제4도중의 일부를 제거하였을 때의 사시도인데, 1은 하우징, 2는 하우징(1)의 개구부를 덮는 캡, 3은 하우징(1)에 지지된 구동축으로서 내연기관의 크랭크축(도시생략)에 동기하여 회전한다.4 is a cross-sectional view of an example of a conventional ignition distributor for an internal combustion engine, and FIG. 5 is a perspective view when a part of the diagram is removed, where 1 is a housing, 2 is a cap covering the opening of the housing 1, and 3 is a housing. As a drive shaft supported by (1), it rotates in synchronization with the crankshaft (not shown) of an internal combustion engine.
4는 하우징(1)내에 고정된 전기신호 발생수단인 홀 효과형 센서로서 자기센서인 홀IC 센서(도시생략) 및 마그네트(도시생략)가 열경화성수지로 고정되어 있다.4 is a Hall effect type sensor which is an electric signal generating means fixed in the housing 1, and a Hall IC sensor (not shown) and a magnet (not shown) which are magnetic sensors are fixed with a thermosetting resin.
5는 구동축(3)에 크랭크(6)를 통하여 나사(7)에 의하여 고착되고 구동축(3)과 일체로 회전하는 자성재료로 된 베인인데, 이 베인(5)은 제6도 및 제7도에 표시한 것과 같이 원판형이며, 또 선단에 90°각도 간격으로 절곡부(5a)가 형성되어 있다. 이 절곡부(5a)는 홀 IC센서와 마그네트의 사이에 형성된 간격(8)을 통과하게 된다.5 is a vane made of a magnetic material which is fixed to the drive shaft 3 by means of a screw 7 via a crank 6 and rotates integrally with the drive shaft 3, which vanes 5 are shown in FIGS. 6 and 7. As shown in Fig. 1, the bent portion 5a is formed in a disc shape at 90 ° angle intervals. This bent portion 5a passes through the gap 8 formed between the Hall IC sensor and the magnet.
9는 구동축(3)의 선단부에 부착되고 구동축(3)과 일체로 회전하는 배전로터로서, 캡(2)에 설치된 중심전극(10)에 근 접되게 로터전극(11)을 갖고 있다.9 is a distribution rotor attached to the distal end of the drive shaft 3 and integrally rotated with the drive shaft 3, and has a rotor electrode 11 in close proximity to the center electrode 10 provided on the cap 2.
12는 캡(2)에 내연기관(도시생략)의 각 기통의 점화플러그(도시생략)에 대응되게 설치된 주변전극으로서, 로터전극(11)을 통하여 순차적으로 점화코일(도시생략)의 2차전압이 배전되어 점화플러그가 착화된다.12 is a peripheral electrode provided in the cap 2 corresponding to the spark plug (not shown) of each cylinder of the internal combustion engine (not shown), and the secondary voltage of the ignition coil (not shown) is sequentially provided through the rotor electrode 11. This power distribution causes the spark plug to ignite.
상기 구성의 내연기관 점화용 배전기에 있어서는, 내연기관의 크랭크축의 회전에 의하여 구동축(3)이 회전하면, 이것과 일체적으로 고착된 베인(5)도 회전하여 절곡부(5a)가 간격(8)을 횡단할 때마다 절곡부(5a)는 마그네트에서 홀 IC센서를 향하여 통과하는 자속을 차단시키며 홀 IC센서에는 구동축(3)의 회전에 따라 자속변화를 일으킨다.In the internal combustion engine ignition distributor having the above-described configuration, when the drive shaft 3 rotates by the rotation of the crankshaft of the internal combustion engine, the vanes 5 integrally fixed thereto are also rotated so that the bent portion 5a is spaced 8. Each time traversing), the bent part 5a blocks the magnetic flux passing from the magnet toward the Hall IC sensor, and the Hall IC sensor causes a magnetic flux change according to the rotation of the drive shaft 3.
이 홀 IC센서에서는 자속변화를 전기신호로 변환되고 이 전기신호는 점화시기 제어유니트(도시생략)에 보내지며 그 결과, 점화코일의 1차전류가 제어되어 점화시기에는 점화코일의 2차전압이 발생한다.In this Hall IC sensor, the magnetic flux change is converted into an electric signal, which is sent to the ignition timing control unit (not shown). As a result, the primary current of the ignition coil is controlled, and the secondary voltage of the ignition coil Occurs.
이 2차전압은 배전로터(9)의 회전에 따라 중심전극(10), 로터전극(11)을 통하여 주변전극(12)에 순차적으로 배전되고, 각 기통의 점화플러그가 순차적으로 착화되어 내연기관은 계속 운전된다.This secondary voltage is sequentially distributed to the peripheral electrode 12 through the center electrode 10 and the rotor electrode 11 as the distribution rotor 9 rotates, and the spark plugs of the respective cylinders are sequentially ignited, thereby causing internal combustion engines. Keeps running.
상기와 같이 구성된 종래의 내연기관 점화용 배전기에 있어서는, 내연기관의 진동에 대하여 베인(5)의 전개도인 제8도의 절결부(5B)에 및 베인(5)을 절곡시켜 형성된 절곡부(5a)의 코너(5c)에는 응력이 집중되기 때문에 내연기관으로 부터의 진동에 의하여 절곡부(5a)가 코너(5c)에서 퍼손되거나, 코너(5c)에 균열이 생기는 문제점이 있었다.In the conventional internal combustion engine ignition distributor configured as described above, the bent portion 5a formed by bending the vanes 5 and the cutout portion 5B of FIG. 8, which is a developed view of the vanes 5, with respect to the vibration of the internal combustion engine. Since stress is concentrated in the corner 5c, the bent portion 5a is collapsed at the corner 5c due to vibration from the internal combustion engine, or there is a problem that the corner 5c is cracked.
이 고안은 이러한 문제점을 해소하기 위해 고안된 것으로서, 베인의 내진성이 대폭적으로 향상된 내연기관 점화용 배전기를 얻는 데 그 목적이 있다.The present invention was devised to solve such a problem, and its purpose is to obtain a distributor for ignition of an internal combustion engine with significantly improved seismic resistance of vanes.
이 고안에 관한 내연기관 점화용 배전기의 베인은 인접된 절곡부간에 내측을 향하여 원호형 곡선부를 갖도록 형성된 것이다.The vane of the internal combustion engine ignition distributor according to the present invention is formed to have an arcuate curved portion inward between adjacent bent portions.
이 고안에 있어서는, 절곡부의 코너부에는 절결부가 없어, 그 만큼 진동에 의한 베이에 대한 코너부의 응력 집중이 감소된다.In this design, the corner portion of the bent portion has no cutout portion, and the stress concentration at the corner portion relative to the bay due to vibration is reduced by that amount.
이 고안의 실시예를 도면에 의하여 설명한다. 제1도는 이 고안의 한 실시예를 나타낸 베인의 평면도, 제2도는 제1도의 측면도, 제3도는 제1도의 베인의 전개도이며, 제4도 내지 제8도와 동일한 부분은 동일부호를 붙이고 그 설명은 생략한다.Embodiments of this invention will be described with reference to the drawings. 1 is a plan view of a vane showing an embodiment of the present invention, FIG. 2 is a side view of FIG. 1, and FIG. 3 is an exploded view of the vane of FIG. 1, and the same parts as in FIGS. Is omitted.
도면에 있어서 20은 제1, 제2, 제3 및 제4의 절곡부(21), (22), (23), (24)를 가진 베인으로서, 각 절곡부간은 베인(20)의 내측을 향하여 원호형 곡선부(26)가 형성되어 있다.In the figure, 20 is a vane having the first, second, third and fourth bent portions 21, 22, 23, and 24, wherein each bent portion has an inner side of the vane 20. The arcuate curved portion 26 is formed.
이와같이 구성된 내연기관 점화용 점화기는제3도의 베인(20)의 전개도에서 알 수 있는 바와같이 종래로부터 있었던 베인(5)의 절결부(5b)는 존재하지 않으므로 그만큼 내연기간의 진동에 의하여 베인(20)의 코너부(25)에 집중하는 응력은 감소되어 베인(20)의 내진성은 대폭적으로 향상된다.The igniter for ignition for the internal combustion engine configured as described above does not have the cutout portion 5b of the vane 5 that has been conventionally known as shown in the developed view of the vane 20 in FIG. The stress concentrated on the corner portion 25 of the) is reduced, and the seismic resistance of the vane 20 is greatly improved.
또한 상기 실시예에서는, 4기통의 내연기관에 사용된 베인이며 4개소에 절곡부(21), (22), (23), (24)이 형성되었지만, 예컨데 6기통의 경우에는 6개소, 8기통의 경우에는 8개소와 같이 기통수에 따라 절곡부의 수가 변하는 것은 물론이다.Also, in the above embodiment, the vanes used for the four-cylinder internal combustion engine are formed with bent portions 21, (22), (23), and (24) in four places, for example, six places and eight in the case of six cylinders. In the case of cylinders, of course, the number of bent portions changes depending on the number of cylinders as in eight places.
또 상기 실시예에서는 전기신호 발생수단으로서 홀 효과형 센서장치에 대하여 설명하였지만, 이에 한정되는 것은 아니고 예컨데 포토다이오드를 사용한 광학식 센서장치라도 무방하다.In addition, although the Hall effect type sensor device has been described as the electric signal generating means in the above embodiment, the present invention is not limited thereto. For example, an optical sensor device using a photodiode may be used.
이상에서 설명한 것과 같이 이 고안의 내연기관 점화용 배전기에 의하면 인접하는 절곡부간에 내측으로 향하여 원호형 곡선부가 있는 베인을 형상함으로서 외력에 의한 절곡부의 코너부에서의 응력집중이 감소되어 내진성이 대폭적으로 향상되는 효과가 있다.As described above, according to the internal combustion engine ignition distributor of the present invention, the vanes having arcuate curved portions are formed inwardly between adjacent bent portions, so that the stress concentration at the corners of the bent portion due to external force is reduced and the seismic resistance is greatly reduced. There is an effect to be improved.
또 베인의 전면적은 종래의 것보다 감소되어 베인제작시 수율이 향상됨과 동시에 베인의 경량화에 의하여 전체의 중량을 저감화 할 수 있는 효과도 있다.In addition, the overall area of the vane is reduced compared to the conventional one, and the yield is improved when manufacturing the vane, and at the same time, the weight of the vane can be reduced to reduce the overall weight.
