Description

터보챠저의 저속구간 강제구동장치Low speed section forced drive system of turbocharger

본 고안은 터보챠저의 저속구간 강제구동장치에 관한 것으로, 상세하게는 엔진의 대중화 추세로 터보의 사용이 보편적이나 저속구간에서의 응답성이 늦어지는것을 개선하여 흡입공기량을 증대시킬 수 있도록 한 터보챠저의 저속구간 강제구동 장체에 관한 것이다.The present invention relates to a forced drive of a low speed section of a turbocharger. In particular, the turbo is a generalized trend of the engine, and the turbo is used to increase the intake air volume by improving the responsiveness in the low speed section. It relates to the body of low speed forced driving of the charger.

일반적으로 터부챠저는 배기가스의 에너지로 배기터빈을 돌리면 이것에 직결된 컴프레서로 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 압력에너지로 바뀌어 압축되어 실린더에 공급하므로 체적효율을 향상시키게 된다.In general, a turbocharger is a device that improves engine output by pushing air into the engine with a compressor directly connected to it when the exhaust turbine is turned on by the energy of exhaust gas. When the exhaust gas is discharged from the engine exhaust stroke, 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. 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. 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 있어 저속구간에서의 응답성을 향상시키고 흡입공기를 초기 시동시부터 충분히 공급하여 저속구간에서도 터보엔진의 성능을 극대화 시킬 수 있도록 하는 데 있다.Therefore, the main purpose of the present invention is to improve the responsiveness in the low speed section in the engine equipped with the 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 2에 나타낸 바와 같이, 본 고안은 샤프트(11)에 기어(12)를 설치한 콤프레서 휠(10)과, 상기 콤프레서 휠(10)의 샤프트(11)와 분리/결합되는 샤프트(21)에 웜기어(22)를 설치한 터빈 휠(20)과, 상기 콤프레서 휠(10)의 기어(12)에 치차결합되어 콤프레서 샤프트(11)를 고속회전시키는 콤프레서 구동기어(40)와, 상기 터빈휠(20)의 웜기어(22)에 치차결합되어 터빈 샤프트(21)를 전진시켜 콤프레서 샤프트(11)에 결합시키는 터빈구동 웜기어(50)와, 상기 콤프레서 구동기어(40)와 터빈구동 웜기어(50)를 동작시키는 구동모터(60)와, 상기 콤프레서 휠(10)의 회전속도를 감지하는 회전수감지센서(70)로 구성한다.As shown in FIG. 2, the present invention includes a compressor wheel 10 having a gear 12 mounted on a shaft 11, and a shaft 21 that is separated / coupled with a shaft 11 of the compressor wheel 10. A turbine wheel 20 provided with a worm gear 22, a compressor drive gear 40 which is geared to the gear 12 of the compressor wheel 10 to rotate the compressor shaft 11 at high speed, and the turbine wheel ( The turbine drive worm gear 50 and the compressor drive gear 40 and the turbine drive worm gear 50 which are gear-coupled to the worm gear 22 of 20) to advance the turbine shaft 21 and couple to the compressor shaft 11 are provided. It consists of a drive motor 60 to operate, and a rotation speed sensor 70 for detecting the rotational speed of the compressor wheel (10).

상기 콤프레서 휠(10)의 샤프트(11)에 설치된 기어(12)에 콤프레서 구동기어(40)를 결합/분리되도록 하되, 항상 결합된 상태를 유지시켜도 무방하다.Compressor drive gear 40 may be coupled / disconnected to gear 12 installed on shaft 11 of compressor wheel 10, but may remain coupled at all times.

이러한 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention is as follows.

터보챠저의 초기시동으로 인한 콤프레서 휠(10)의 저속회전시 콤프레서 휠(10)의 샤프트(11)에 설치된 기어(12)에 콤프레서 구동기어(40)를 치차결합시키고, 콤프레서 구동기어(40)를 구동모터(60)가 작동시켜 고속회전시킨다.When the compressor wheel 10 rotates at low speed due to the initial startup of the turbocharger, the compressor drive gear 40 is geared to the gear 12 installed on the shaft 11 of the compressor wheel 10. Drive motor 60 is operated to rotate at high speed.

따라서, 콤프레서 휠(10)의 샤프트(11)가 고속회전하게 됨으로 콤프레서 휠(10)이 고속회전된다.Accordingly, the compressor wheel 10 is rotated at high speed because the shaft 11 of the compressor wheel 10 is rotated at high speed.

한편, 고속구간에서는 터빈 휠(20)의 샤프트(21)에 설치된 웜기어(22)와 치차결합된 터빈구동 웜기어(50)를 구동코터(60)가 회전시켜 샤프트(21)를 콤프레서 휠(10)의 샤프트(11)측으로 이동시켜 결합되도록 함으로써 콤프레서 휠(10)과 터빈 휠(20)이 연동되어 회전하게 한다.On the other hand, in the high speed section, the drive coater 60 rotates the turbine drive worm gear 50, which is geared to the worm gear 22 installed on the shaft 21 of the turbine wheel 20, to rotate the shaft 21 to the compressor wheel 10. By moving to the shaft 11 side of the compressor wheel 10 and the turbine wheel 20 is interlocked to rotate.

이상에서 살펴본 바와 같이, 본 고안은 터보챠저의 저속구간에서 콤프레서휠을 강제구동시켜 응답성을 향상시키고, 흡입공기를 초기 시동시부터 충분히 공급하여 저속구간에서도 터보엔진의 성능을 극대화 시키는 효과가 있다.As described above, the present invention improves 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. .
