Abstract

PURPOSE: An electronic throttle control actuator is provided to reduce noise and to improve the durability by installing a motor turning a throttle valve flap by a controller in an actuator housing firmly and stably with an insertion ring. CONSTITUTION: A throttle valve flap is installed to an actuator housing, and turned by receiving power from a motor mounted in a motor installation part of the actuator housing. A throttle position sensor detects turning of the throttle valve flap, and a cover restricts the motor in the motor installation part of the actuator housing. The outer periphery of a stepped part of the motor is surrounded by the inner periphery of an insertion ring(13), and the outer periphery of the insertion ring is inserted to the motor installation part of the actuator housing to install the motor in the actuator housing firmly. An elastic force supply unit is integrally formed in the insertion ring to apply elastic force evenly and entirely in radial direction in the circumference of the insertion ring.

종래에는 상기 스로틀밸브를 운전자의 가속페달과 연결된 와이어 등을 이용하여 기계적으로 개폐하도록 하였는데, 최근에는 운전자의 가속페달 조작력 및 각종 차량의 운전상태 등을 전기적인 신호로 반영하여 작동되는 전자식 스로틀 컨트롤 액츄에이터를 사용하여 보다 향상된 엔진성능을 발휘할 수 있도록 하고 있다.

In recent years, an electronic throttle control actuator is operated by reflecting the driver's accelerator pedal operation force and driving conditions of various vehicles as electrical signals. By using to improve the engine performance.

본 발명은 상기한 바와 같은 전자식 스로틀 컨트롤 액츄에이터에서 컨트롤러의 제어를 받아 실질적으로 스로틀밸브플랩을 회동시키는 회전력을 발생시키는 모터를 액츄에이터하우징에 견고하고 안정된 상태로 장착할 수 있도록 함으로써, 소음의 발생을 억제하고 내구성을 향상시킬 수 있도록 한 전자식 스로틀 컨트롤 액츄에이터를 제공함에 그 목적이 있다.The present invention is to suppress the generation of noise by allowing the electronic throttle control actuator to be mounted in the actuator housing in a rigid and stable state that generates a rotational force that substantially rotates the throttle valve flap under the control of the controller. Its purpose is to provide an electronic throttle control actuator that can improve the durability and durability.

상기 삽입링은 삽입링의 전체 원주에 걸쳐서 반경방향으로 고른 탄성력을 제공할 수 있는 탄성력제공수단이 일체로 구비된 것을 특징으로 한다.The insertion ring is characterized in that the elastic force providing means that can provide a uniform elastic force in the radial direction over the entire circumference of the insertion ring is integrally provided.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1 과 도 2는 본 발명에 따른 전자식 스로틀 컨트롤 액츄에이터에 사용되는 삽입링의 구조를 도시한 도면이고, 도 3은 도 1의 삽입링이 전자식 스로틀 컨트롤 액츄에이터에 장착되는 상태를 설명한 분해 사시도이다.1 and 2 are views showing the structure of the insertion ring used in the electronic throttle control actuator according to the present invention, Figure 3 is an exploded perspective view illustrating a state in which the insertion ring of Figure 1 is mounted to the electronic throttle control actuator.

도 3을 통해 본 발명에 따른 전자식 스로틀 컨트롤 액츄에이터의 대체적인 구성을 살펴보면, 액츄에이터하우징(1)에 스로틀밸브플랩(3)이 회동 가능하게 장착되도록 되어 있고, 상기 스로틀밸브플랩(3)은 상기 액츄에이터하우징(1)의 모터장착부(11)에 설치되는 모터(9)로부터 동력을 전달 받아 회동되며, 상기와 같은 스로틀밸브플랩(3)의 회동상태는 스로틀포지션센서(15)에 의해 감지되도록 되어 있고, 상기 스로틀포지션센서(15)를 일체로 내장한 커버(33)가 상기 모터(9)를 액츄에이터하우징(1)의 모터장착부(11)내에 구속시키는 상태로 장착되도록 되어 있다.Looking at the alternative configuration of the electronic throttle control actuator according to the invention through Figure 3, the throttle valve flap (3) is rotatably mounted to the actuator housing (1), the throttle valve flap (3) is the actuator It is rotated by receiving power from the motor 9 installed in the motor mounting portion 11 of the housing 1, the rotation state of the throttle valve flap (3) as described above is to be detected by the throttle position sensor (15) The cover 33 having the throttle position sensor 15 integrated therein is mounted so as to restrain the motor 9 in the motor mounting portion 11 of the actuator housing 1.

상기 모터(9)에는 상기 삽입링(13)의 두께를 흡수할 수 있는 단차부(17)가 형성되어 있으며, 상기 삽입링(13)은 내측 원주면이 상기 모터(9)의 단차부(17) 외주면을 감싸고, 외측 원주면이 액츄에이터하우징(1)의 모터장착부 내측에 삽입되어 상기 액츄에이터하우징(1)에 대한 모터(9)의 삽입 상태를 견고히 하게 되어 있는데,The motor 9 is provided with a stepped portion 17 that can absorb the thickness of the insertion ring 13, and the insertion ring 13 has an inner circumferential surface of the stepped portion 17 of the motor 9. The outer circumferential surface is wrapped, and the outer circumferential surface is inserted inside the motor mounting portion of the actuator housing 1 to firmly insert the motor 9 into the actuator housing 1,

이는 상기 삽입링(13)에 구비된 탄성력제공수단이 삽입링(13)의 전체 원주에 걸쳐서 반경방향으로 고른 탄성력을 제공할 수 있도록 하기 때문이다.This is because the elastic force providing means provided in the insertion ring 13 can provide an even elastic force in the radial direction over the entire circumference of the insertion ring 13.

본 실시예에서 상기 삽입링(13)은 도 1에 도시된 것처럼 자유상태에서 원주의 일부에 틈(19)이 구비된 원형으로 구부러진 금속띠로 형성하였으며, 상기 탄성력제공수단은 상기 삽입링(13)의 원주면 일부가 절개되어 절곡된 탄지판(21)이 삽입링(13)의 원주방향으로 고르게 배치되도록 하여 구성하였다.In the present embodiment, the insertion ring 13 is formed in a circular bent metal belt provided with a gap 19 in a part of the circumference as shown in Figure 1, the elastic force providing means is the insertion ring 13 A portion of the circumferential surface of the bent and folded bent finger plate 21 was configured to be evenly arranged in the circumferential direction of the insertion ring (13).

따라서, 상기 모터(9)는 상기 액츄에이터하우징(1)에 견고한 상태로 고정되며, 그 고정상태는 상기 탄지판(21)들이 상기 모터(9)를 상기 액츄에이터하우징(1)의 모터장착부(11) 내주면과 모터(9)의 외주면 사이에 작용하는 탄성력에 의해 지속적으로 유지된다.Therefore, the motor 9 is fixed to the actuator housing 1 in a rigid state, and the fixed state is that the fingerboards 21 allow the motor 9 to attach the motor 9 to the motor mounting portion 11 of the actuator housing 1. It is continuously maintained by the elastic force acting between the inner circumferential surface and the outer circumferential surface of the motor 9.

또한, 상기와 같이 다수의 탄지판(21)들이 모터장착부(11) 내주면과 모터(9)의 외주면 사이에 원주방향을 따라 고르게 탄성력을 제공함에 따라서, 상기 모터(9)의 회전축은 상기 스로틀밸브플랩(3)까지 회전력을 전달하는 동력전달계에 정확하고 안정된 회전축 상태를 지속적으로 제공하게 되어, 항상 정숙한 전자식 스로틀 컨트롤 액츄에이터의 작동이 이루어지게 된다.In addition, as described above, as the plurality of finger plates 21 provide elastic force evenly in the circumferential direction between the inner circumferential surface of the motor mounting portion 11 and the outer circumferential surface of the motor 9, the rotation shaft of the motor 9 is the throttle valve. By providing the power transmission system that transmits the rotational force to the flap (3) continuously provides an accurate and stable rotation axis state, the operation of the quiet electronic throttle control actuator is always made.

이상과 같이 본 발명에 의하면, 전자식 스로틀 컨트롤 액츄에이터에서 컨트롤러의 제어를 받아 실질적으로 스로틀밸브플랩을 회동시키는 회전력을 발생시키는 모터를 상기와 같은 삽입링을 사용하여 액츄에이터하우징에 견고하고 안정된 상태로 장착할 수 있도록 함으로써, 전자식 스로틀 컨트롤 액츄에이터의 소음의 발생을 억제하고 내구성을 향상시킬 수 있다. As described above, according to the present invention, a motor that generates a rotational force that substantially rotates the throttle valve flap under the control of the controller in the electronic throttle control actuator can be mounted in the actuator housing in a rigid and stable state using the insertion ring as described above. By doing so, it is possible to suppress generation of noise of the electronic throttle control actuator and to improve durability.
