Description
본 고안은 터보챠저의 저속구간 강제구동장치에 관한 것으로, 상세하게는 엔진의 대중화 추세로 터보의 사용이 보편적이나 저속구간에서의 응답성이 늦어지는 것을 개선하여 흡입공기량을 증개시킬 수 있도록 한 터보챠저의 저속구간 강제구동 장치에 관한 것이다.The present invention relates to a forced drive device of a low speed section of a turbocharger, and in particular, the use of the turbo due to the popularization of the engine is general, but the turbo which improves the responsiveness in the low speed section to increase the intake air volume. It relates to a low speed forced drive device of the charger.
일반적으로 터보챠저는 배기가스의 에너지로 배기터빈을 돌리면 이것에 직결된 콤프레서의 엔진에 공기를 밀어 넣어 엔진출력을 향상시키는 장치로서 엔진의 배기행정에서 배기가스가 배출되면서 배기쪽의 터빈을 회전시키면 흡입쪽의 임펠러도 하전하므로 임펠러 중심부근의 공기는 원심력을 받아 외곽으로 가속되어 디퓨저에 들어가고, 디퓨저는 공기통로의 면적이 크기 때문에 공기의 속도에너지가 압력 에너지로 바뀌어 압축되어 실린더에 공급하므로 체적효율을 향상시키게 된다.In general, a turbocharger is a device that improves engine output by pushing air into the engine of a compressor directly connected to the energy of exhaust gas. When a turbocharger is discharged from an exhaust stroke of an engine, the turbine on the exhaust side is rotated. As the impeller on the suction side is also charged, the air near the center of the impeller is accelerated to the outside under centrifugal force and enters the diffuser, and since the area of the air passage is large, the velocity energy of the air is converted into pressure energy and compressed and supplied to the cylinder, thereby increasing the volumetric efficiency. Will improve.
도 1은 종래의 터보챠저 요부구성도이다.1 is a configuration diagram of a conventional turbocharger.
도 1에 나타낸 바와 같이, 종래에는 콤프레서 휠(10)과 터빈 휠(20)을 터보챠저 샤프트(30)로 연결하여 구성하였다.As shown in FIG. 1, the compressor wheel 10 and the turbine wheel 20 were conventionally comprised by connecting the turbocharger shaft 30. As shown in FIG.
그러나, 이러한 종래의 터보챠저는 저속구간에서 콤프레서 휠(10)의 회전수도 저하되어 응답성이 늦어질 뿐 아니라 터보엔진의 효율이 떨어지는 문제점이 있었다.However, such a conventional turbocharger has a problem that the rotation speed of the compressor wheel 10 is also lowered in the low speed section, resulting in a slow response and a decrease in the efficiency of the turbo engine.
따라서, 본 고안의 주 목적은 터보챠저가 장착된 엔진에 있어서 저속구간에서의 응답성을 향상시키고 흡입공기를 초기 시동시부터 충분히 공급하여 저속구간에서도 터보엔진의 성능을 극대화시킬 수 있도록 하는 데 있다.Therefore, the main object of the present invention is to improve the responsiveness in the low speed section in the engine equipped with a turbocharger and to maximize the performance of the turbo engine even in the low speed section by supplying sufficient intake air from the initial startup. .

위와 같이 구성된 본 고안의 실시예를 첨부된 도면을 참조하면서 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings an embodiment of the present invention configured as described above are as follows.
도 2는 본 고안의 터보챠저 요부구성도이다.2 is a main configuration of the turbocharger of the present invention.
도 2에서 나타낸 바와 같이, 본 고안은 콤프레서 휠(10)과 터빈 휠(20)을 연결하고, 이원화시켜 분리/결합되게 한 터보챠저 샤프트(30a,30b)와, 상기 콤프레서 휠(10)측의 터보챠저 샤프트(30a) 외주연에 결합시킨 콤프레서 기어(40)와, 상기 콤프레서 기어(40)에 결합/분리되는 터보챠저 구동기어(50)와, 상기 터보챠저 구동기어(50)를 제어하는 구동모터(60)와, 상기 콤프레서 휠(10)의 회전속도를 감지하는 회전수 감지센서(70)로 구성한다.As shown in FIG. 2, the present invention connects the compressor wheel 10 and the turbine wheel 20, and dualizes the turbocharger shafts 30a and 30b to separate and couple the compressor wheel 10 and the compressor wheel 10 side. A compressor gear 40 coupled to an outer circumference of the turbocharger shaft 30a, a turbocharger drive gear 50 coupled to and separated from the compressor gear 40, and a drive for controlling the turbocharger drive gear 50. The motor 60 and the rotation speed sensor 70 for detecting the rotational speed of the compressor wheel 10 are configured.
상기 콤프레서 휠(10)측의 터보챠저 샤프트(30a)에 설치된 콤프레서 기어(40)에 터보챠저 구동기어(50)를 결합/분리 되도록 하되, 항상 결합된 상태로 설치하여도 무방하다.The turbocharger drive gear 50 may be coupled / disconnected to the compressor gear 40 installed in the turbocharger shaft 30a on the compressor wheel 10 side, but may be installed in a coupled state at all times.
이러한 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention is as follows.
터보챠저의 초기시동 등으로 인한 콤프레서 휠(10)의 저속회전시 콤프레서 휠(10)의 터보챠저 샤프트(30a)에 설치된 콤프레서 기어(40)에 터보챠저 구동기어(50)를 치차결합시키고 터보챠저 구동기어(50)를 구동모터(60)가 작동시켜 고속회전시킨다.The turbocharger drive gear 50 is geared to the compressor gear 40 installed in the turbocharger shaft 30a of the compressor wheel 10 at low speed rotation of the compressor wheel 10 due to the initial startup of the turbocharger. The drive motor 50 drives the drive gear 50 to rotate at high speed.
따라서, 터보챠저 구동기어(50)의 고속회전으로 콤프레서 기어(40)도 고속회전하여 터보챠저 샤프트(30a)를 고속회전 시킴으로써 콤프레서 휠(10)을 고속회전시킨다.Therefore, the compressor gear 40 also rotates at high speed by the high speed rotation of the turbocharger drive gear 50, and the compressor wheel 10 is rotated at high speed by rotating the turbocharger shaft 30a at high speed.
한편, 고속구간에서는 이원화된 콤프레서 샤프트(30a,30b)를 연결하여 터빈 휠(20)이 회전하여 터보챠저가 구동되게 한다.Meanwhile, in the high speed section, the turbine compressor 20 is rotated by connecting the dual compressor shafts 30a and 30b to drive the turbocharger.
이상에서 살펴본 바와 같이, 본 고안은 터보챠저의 저속구간에서 콤프레서 휠을 강제구동시켜 응답성을 향상시키고, 흡입공기를 초기 시동시부터 충분히 공급하여 저속구간에서도 터보엔진의 성능을 극대화시키는 효과가 있다.As described above, the present invention improves the response by forcibly driving the compressor wheel in the low speed section of the turbocharger, and provides sufficient intake air from the initial startup, thereby maximizing the performance of the turbo engine in the low speed section. .
