도 2는 본 발명의 바람직한 실시예에 다른 토크 컨버터의 부분 단면도.2 is a partial cross-sectional view of a torque converter according to a preferred embodiment of the present invention.
도 3은 도 2의 'A' 부 확대 도면.3 is an enlarged view of a portion 'A' of FIG. 2;
상기 목적을 달성하기 위한 본 발명의 토크 컨버터는, 임펠러 플레이트와 함께 회전되는 임펠러 쉘과, 상기 임펠러 쉘의 내부에서 상기 임펠러 쉘과 일정 간격을 두고, 터빈 날개와 함께 회전하는 터빈 쉘을 구비하는 토크 컨버터에 있어서, 상기 임펠러 플레이트와 상기 터빈 날개 사이의 공간부 상측의 상기 임펠러 쉘의 내측면은 상기 공간부를 일정 거리 덮도록 돌출 형성된 것을 특징으로 한다.The torque converter of the present invention for achieving the above object is a torque having an impeller shell rotated together with an impeller plate, and a turbine shell rotated together with the turbine blades at a predetermined distance from the impeller shell inside the impeller shell. In the converter, the inner surface of the impeller shell on the upper side of the space between the impeller plate and the turbine blades is characterized in that the protrusion formed so as to cover a predetermined distance.
이하 본 발명의 바람직한 실시예에 따른 토크 컨버터를 첨부된 도면을 참조하여 상세히 설명한다. 그러나 본 발명은 이하에서 개시되는 실시예에 한정되는 것이 아니라 서로 다른 다양한 형태로 구현될 것이며, 단지 본 실시예는 본 발명의 개시가 완전하도록 하며, 통상의 지식을 가진자에게 발명의 범주를 완전하게 알려주기 위해 제공되는 것이다.Hereinafter, a torque converter according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the present embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you.
도 2는 본 발명의 바람직한 실시예에 다른 토크 컨버터의 부분 단면도이고, 도 3은 도 2의 'A' 부 확대 도면이다.2 is a partial cross-sectional view of a torque converter according to a preferred embodiment of the present invention, and FIG. 3 is an enlarged view of portion 'A' of FIG.
도 2 및 도 3에 도시된 바와 같이, 본 발명에 따른 토크 컨버터(100)는, 임펠러 플레이트(10)와 함께 회전되는 임펠러 쉘(20)과, 임펠러 쉘(20)의 내부에서 임펠러 쉘(20)과 일정 간격을 두고, 터빈 날개(30)와 함께 회전하는 터빈 쉘(40)을 구비하는 토크 컨버터에 있어서, 상기 임펠러 플레이트(10)와 터빈 날개(30) 사이의 공간부(50) 상측의 임펠러 쉘(20)의 내측면은 공간부(50)를 일정 거리 덮도록 돌출 형성된다.2 and 3, the torque converter 100 according to the present invention includes an impeller shell 20 rotated together with the impeller plate 10, and an impeller shell 20 inside the impeller shell 20. In a torque converter having a turbine shell 40 that rotates together with the turbine blades 30 at a predetermined distance, the upper portion of the space 50 between the impeller plate 10 and the turbine blades 30. The inner surface of the impeller shell 20 is formed to protrude so as to cover the space 50.
이하 본 발명의 토크 컨버터(100)의 작동을 설명하면, 도 3에 도시된 바와 같이, 임펠러 플레이트(10)의 회전에 따른 순환 유량(60)이 발생되면, 순환 유량(60)은 터빈 날개(30) 측으로 전달되게 된다. 이러한 순환 유량(60)은 공간부(50) 상측의 임펠러 쉘(20)이 공간부(50) 상측을 일정 거리 덮도록 형성됨에 의하여, 순환 유량(60)이 누유되는 것을 방지하여 토크비가 저하됨을 방지한다.Referring to the operation of the torque converter 100 of the present invention, as shown in Figure 3, when the circulating flow rate 60 is generated according to the rotation of the impeller plate 10, the circulating flow rate 60 is turbine blade ( 30) will be delivered to the side. The circulation flow rate 60 is formed so that the impeller shell 20 above the space portion 50 covers the upper portion of the space portion 50 by a predetermined distance, thereby preventing leakage of the circulation flow rate 60, thereby reducing the torque ratio. prevent.
상기와 같은 본 발명에 따른 토크 컨버터는 다음과 같은 효과를 갖는다.The torque converter according to the present invention as described above has the following effects.
임펠러 플레이트에서 발생된 유압이 임펠러 쉘과 터빈 쉘 사이의 공간부에서 유출되지 않도록 임펠러 쉘의 내측면을 돌출 형성시킴으로써, 토크비 저감을 방지한다.By protruding the inner surface of the impeller shell so that the hydraulic pressure generated in the impeller plate does not flow out of the space between the impeller shell and the turbine shell, the torque ratio reduction is prevented.
