일반적으로, 인휠 구동장치는 전기 자동차와 같이 전기를 동력원으로 사용하는 자동차에 사용되는 기술로서, 가솔린 또는 디젤 자동차에서의 엔진과 미션 및 구동축을 통한 동력 전달에 의해 바퀴가 회전 구동하는 방식과는 달리, 좌우의 구동륜 또는 좌우 및 전후 4개의 구동륜 내부에 배치되는 모터에 의해 동력이 휠에 직접 전달되는 기술이다.Generally, an in-wheel drive device is a technology used for an automobile that uses electricity as a power source, such as an electric vehicle. Unlike a method in which a wheel is rotated by driving power transmitted through an engine, a mission and a drive shaft in a gasoline or diesel vehicle , And the power is transmitted directly to the wheels by the left and right drive wheels or motors disposed in the right and left and front and rear four drive wheels.

유성기어(26)는 썬기어(22)와 링기어(24)에 치합되므로, 썬기어(22)의 회전에 따라 유성기어(26)는 자전을 하면서 썬기어(22)의 주변을 회전한다.The planetary gear 26 is engaged with the sun gear 22 and the ring gear 24 so that the planetary gear 26 rotates around the sun gear 22 while rotating as the sun gear 22 rotates.

모터부(10)의 구동축(17)과 썬기어(22)의 회전 중심은 일치하므로, 구동축(17)에서 썬기어(22)로 동력전달이 용이하게 이루어진다.The rotation center of the drive shaft 17 of the motor unit 10 and the sun gear 22 are coincident with each other so that power transmission from the drive shaft 17 to the sun gear 22 is facilitated.

유성기어(26)가 썬기어(22)에 치합되어 자전하면서 공전하므로 감속이 이루어지며, 이러한 유성기어(26)를 회전 가능하게 지지하는 캐리어(28)를 통해 회전동력이 출력된다.The planetary gear 26 is engaged with the sun gear 22 and revolves while revolving while rotating. The rotational power is output through the carrier 28 that rotatably supports the planetary gear 26.

캐리어(28)는 모터부(10)의 외측에 설치된 제2감속부(30)에 연결되어 감속이 이루어진다.The carrier 28 is connected to the second deceleration section 30 provided on the outer side of the motor section 10 to decelerate it.

모터부(10)의 내측에 설치된 제1감속부(20)에서 1차 감속이 이루어지며, 모터부(10)의 외측에 설치된 제2감속부(30)에서 2차 감속이 이루어진 후, 휠부재(90)에 연결된 허브외륜(50)을 회전시키므로, 타이어(96)가 장착된 휠부재(90)의 회전이 이루어진다.The first deceleration is performed at the first deceleration portion 20 provided inside the motor portion 10 and the second deceleration portion is provided at the second deceleration portion 30 provided outside the motor portion 10, The hub outer ring 50 connected to the hub 90 is rotated to rotate the wheel member 90 on which the tire 96 is mounted.

구동기어(36)로 동력을 전달하는 연결축부재(32)는 캐리어(28)에 축 연결되므로, 회전동력이 전달된다.Since the connecting shaft member 32 for transmitting the power to the driving gear 36 is connected to the carrier 28, the rotational power is transmitted.

휠부재(90)의 회전중심에 설치되는 허브내륜(52)은, 차체에 고정되는 하우징(80)에 일측(도 1기준 좌측)이 고정된다.The hub inner ring 52 provided at the rotation center of the wheel member 90 is fixed to one side (the left side in FIG. 1) of the housing 80 fixed to the vehicle body.

허브내륜(52)의 외측에는 마찰을 감소시키는 허브베어링(42)이 설치되며, 허브베어링(42)을 감싸며 회전 가능하게 허브외륜(50)이 설치된다.A hub bearing 42 for reducing friction is provided on the outer side of the hub inner ring 52 and a hub outer ring 50 is installed so as to surround the hub bearing 42 so as to be rotatable.

허브외륜(50)은 파이프 형상으로 형성되며, 이러한 허브외륜(50)의 타측(도 1기준 우측)은 휠부재(90)의 내측벽(94)에 고정된다.The hub outer ring 50 is formed in a pipe shape and the other side (reference right side in FIG. 1) of the hub outer ring 50 is fixed to the inner wall 94 of the wheel member 90.

허브외륜(50)의 둘레를 따라 구동기어(36)와 치합되는 종동기어(38)가 설치되므로, 종동기어(38)의 회전에 따라 종동기어(38) 및 허브외륜(50)이 동시에 회전된다.The driven gear 38 and the hub outer ring 50 are simultaneously rotated in accordance with the rotation of the driven gear 38 because the driven gear 38 is engaged with the drive gear 36 along the periphery of the hub outer ring 50 .

허브외륜(50)은 허브내륜(52)에 의해 지지되며, 외력에 의해 회전되어 휠부재(90)를 회전시킨다.The hub outer ring 50 is supported by the hub inner ring 52 and is rotated by an external force to rotate the wheel member 90.

허브외륜(50)의 회전중심은 휠부재(90)의 회전중심과 일치하며, 구동축(17)과 휠부재(90)의 회전중심 사이의 거리(D)는, 구동기어(36)의 반경과 종동기어(38)의 반경의 합이다.The center of rotation of the hub outer ring 50 coincides with the center of rotation of the wheel member 90 and the distance D between the drive shaft 17 and the center of rotation of the wheel member 90 is equal to the radius of the drive gear 36 And the sum of the radii of the driven gears 38. [

예를 들어, 구동축(17)과 휠부재(90)의 회전중심 사이의 거리(D)가 50cm인 경우, 구동기어(36)의 반경이 10cm 이며 종동기어(38)의 반경이 40cm로 이루어지므로, 구동축(17)과 휠부재(90)의 회전중심 사이의 거리(D)는, 구동기어(36)의 반경과 종동기어(38)의 반경의 합과 같다.For example, when the distance D between the drive shaft 17 and the center of rotation of the wheel member 90 is 50 cm, the radius of the drive gear 36 is 10 cm and the radius of the driven gear 38 is 40 cm The distance D between the drive shaft 17 and the center of rotation of the wheel member 90 is equal to the sum of the radius of the drive gear 36 and the radius of the driven gear 38. [

휠부재(90)의 내측에는 절곡 형성된 디스크(60)가 고정되며, 이러한 디스크(60)의 단부는 하우징(80)에 결합된 캘리퍼(70)에 접촉되어 회전이 구속된다.A bent disk 60 is fixed to the inside of the wheel member 90 and the end of the disk 60 contacts the caliper 70 coupled to the housing 80 to restrict rotation.

캘리퍼(70)는, 브레이크 패달과 연동되는 패드(72)가 구비되며, 이러한 패드(72)는 디스크(60)에 접하여 마찰을 발생시키므로, 휠부재(90)의 회전을 구속한다. The caliper 70 is provided with a pad 72 interlocked with a brake pedal and such a pad 72 generates frictional contact with the disk 60 and thus restrains the rotation of the wheel member 90.

하우징(80)은 차체에 고정될 수 있으며, 휠부재(90)의 각도를 조절하는 조향축(85)에 설치될 수도 있다.The housing 80 may be fixed to the vehicle body and may be installed on the steering shaft 85 for adjusting the angle of the wheel member 90.

휠부재(90)는, 허브외륜(50)과 일체로 회전되며 외측 둘레를 따라 타이어(96)가 설치되는 기술사상 안에서 다양한 변형 실시가 가능하다.The wheel member 90 can be variously modified within the technical idea in which the tire 96 is installed along the outer periphery while being rotated integrally with the hub outer ring 50.

휠부재(90)는 타이어(96)를 지지하는 링 형상의 지지휠(92) 및 지지휠(92)의 중앙 개구된 부분을 폐쇄하는 내측벽(94)을 포함한다.The wheel member 90 includes a ring shaped support wheel 92 that supports the tire 96 and an inner wall 94 that closes the central open portion of the support wheel 92.

제1감속부(20)와 제2감속부(30)를 따라 윤활 작용을 하는 오일의 이동통로를 형성하는 윤활용 유로(34)가 연결축부재(32) 및 캐리어(28)의 내측에 구비된다.A lubricating oil passage 34 for forming a lubricating oil passage along the first reduction portion 20 and the second reduction portion 30 is provided inside the connection shaft member 32 and the carrier 28 .

이러한 윤활용 유로(34) 및 냉각용 유로(12)로 오일을 공급하는 오일펌프(100)가 제1감속부(20)와 제2감속부(30)의 사이에 설치된다.An oil pump 100 for supplying oil to the lubricating oil passage 34 and the cooling oil passage 12 is provided between the first deceleration portion 20 and the second deceleration portion 30.

허브내륜(52)의 외측에서 회전되는 허브외륜(50)의 외측면에는 씰링(44)이 설치되어, 하우징(80)의 외측으로 오일의 누설을 방지한다.A sealing ring 44 is provided on the outer surface of the hub outer ring 50 which is rotated outside the hub inner ring 52 to prevent leakage of the oil to the outside of the housing 80.

이하에서는 첨부된 도면들을 참조하여 본 발명의 일 실시예에 따른 인휠 구동장치(1)의 작동상태를 상세히 설명한다.Hereinafter, the operating state of the in-wheel driving apparatus 1 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

썬기어(22)의 회전으로 유성기어(26)가 자전을 하면서 썬기어(22)의 둘레를 공전하며, 유성기어(26)를 지지하는 캐리어(28)도 회전된다.The rotation of the sun gear 22 causes the planetary gear 26 to revolve while revolving the circumference of the sun gear 22 and the carrier 28 to support the planetary gear 26 is also rotated.

구동기어(36)에 치합된 종동기어(38)가 회전되면, 종동기어(38)와 연결된 허브외륜(50)은 허브내륜(52)을 중심으로 회전되므로, 허브외륜(50)과 연결된 휠부재(90)가 회전된다.The hub outer ring 50 connected to the driven gear 38 is rotated about the hub inner ring 52 so that the wheel member 38 connected to the hub outer ring 50 is rotated, (90) is rotated.
