Description
본 고안은 자동차용 프리휠허브에 관한 것이다.The present invention relates to a freewheel hub for automobiles.
일반적으로 프리휠허브(free-wheel hub)는 4륜구동 자동차의 앞바퀴의 허브에서 프런트 액슬과 휠을 기계적으로 단속하는 클러치의 역할을 하는 것으로, 허브에 장착되어 있으며 손잡이를 돌리는 회전형식인 것과 운전석에 설치되어 있으며 스위치에 의하여 단속하는 것이 있다.In general, a free-wheel hub acts as a clutch that mechanically clamps the front axle and wheels at the hub of the front wheels of a four-wheel drive vehicle. There is an interruption by a switch.
종래 프리휠허브(10)는 도 1에 도시된 것과 같이, 액슬축(20)에 결합되어 선택적으로 회동가능하게 설치됨과 더불어, 타이어가 설치된 휠(30)에 보울트(40)를 매개로 회전력을 전달할 수 있도록 설치되어 있다.As shown in FIG. 1, the conventional freewheel hub 10 is coupled to the axle shaft 20 to be selectively rotatable, and transmits rotational force through the bolt 40 to the wheel 30 on which the tire is installed. It is installed so that.
여기서 프리휠허브(10)는 도 1에 도시된 것과 같이 중심선 상부는 진공상태이고 하부는 진공상태가 해제된 것을 나타낸 것으로, 도시되지 않은 너클로부터 진공상태가 되면 너클쪽으로 이동되는 다이아프램(11)과, 이 다이아프램(11)에 의해 너클쪽으로 이동되는 제1기어(12)와, 이 제1기어(12)와 치합됨과 더불어 상기 액슬축(20)과 스플라인 결합된 제2기어(13)와, 상기 휠(30)과 보울트(40)를 매개로 결합됨과 더불어 제1기어(12)와 치합된 허브하우징(14)과, 상기 제2기어(13)의 외주면에 끼워짐과 더불어 허브하우징(14)의 내주면에 끼워진 스냅링(15)에 의해 지지되는 지지구(16)와, 이 지지구(16)에 의해 지지됨과 더불어 상기 제1기어(12)를 탄발력에 의해 다이아프램(11)쪽으로 밀어부치도록 설치된 스프링(17) 등으로 구성되어 있다.Here, as shown in FIG. 1, the freewheel hub 10 shows that the upper part of the center line is in a vacuum state and the lower part is in a vacuum state. A first gear 12 moved toward the knuckle by the diaphragm 11, a second gear 13 splined to the axle shaft 20 and meshed with the first gear 12; The hub housing 14 coupled to the wheel 30 and the bolt 40 and engaged with the first gear 12 and the outer peripheral surface of the second gear 13 and the hub housing 14 are fitted together. The support 16 supported by the snap ring 15 fitted to the inner circumferential surface of the < RTI ID = 0.0 >), < / RTI > the support 16 and the first gear 12 pushed toward the diaphragm 11 by elastic force. It consists of the spring 17 etc. which were provided so that it may be attached.
따라서 상기 액슬축(20)을 따라 진공은 다이아프램(11)을 휠(30)쪽으로 당기게 되고, 이때 이 다이아프램(11)에 의해 상기 허브하우징(14)과 치합된 제1기어(12)를 밀어부쳐 제2기어(13)와 치합하게 된다.Accordingly, the vacuum along the axle shaft 20 pulls the diaphragm 11 toward the wheel 30, and at this time, the first gear 12 engaged with the hub housing 14 by the diaphragm 11 is pulled out. It is pushed to engage with the second gear 13.
이후 상기 제2기어(13)에 액슬축(20)으로부터 전달된 회전력이 제1기어(12)와 허브하우징(14)을 통해 휠(30)로 전달됨으로써 2륜구동에서 4륜구동으로 되게 된다.Thereafter, the rotational force transmitted from the axle shaft 20 to the second gear 13 is transmitted to the wheel 30 through the first gear 12 and the hub housing 14 so that the two-wheel drive becomes four-wheel drive.
한편 진공상태가 해제되면 상기 다이아프램(11)은 상기 스프링(17)에 의해 휠(30)의 반대쪽으로 되돌아가고 이때 제1기어(12)도 밀리게 되어 제2기어(13)와의 치합이 해제됨으로써 액슬축(20)의 회전력이 휠(30)에 전달되지 않게 된다.On the other hand, when the vacuum is released, the diaphragm 11 is returned to the opposite side of the wheel 30 by the spring 17, and at this time, the first gear 12 is pushed back so that the engagement with the second gear 13 is released. By doing so, the rotational force of the axle shaft 20 is not transmitted to the wheel 30.
그런데 이러한 종래 프리휠허브는 많은 부품이 필요하고 구조도 복잡하여 정비성이 나쁨은 물론 제조비용이 높은 결점이 있는 한편, 각 바퀴의 속도차에 의해 4륜구동에서 2륜구동으로 돌아갈 때 제1기어가 제2기어에서 빠지지 않는 결점이 있었다.However, such a conventional freewheel hub requires a lot of parts and a complicated structure, which is poor in maintainability and high in manufacturing cost. On the other hand, when the first gear returns from four wheel drive to two wheel drive due to the speed difference of each wheel, There was a flaw that could not fall out of the second gear.
이에 본 고안은 상기와 같은 결점을 해결하기 위해 안출된 것으로, 액슬축으로부터 전달되는 회전력에 의해 회전되는 내측마찰부재가 진공압에 의해 작동되는 외측마찰부재에 회전력을 전달하여 휠과 결합된 허브하우징을 회전시킴으로써 2륜구동에서 4륜구동으로 변환하는 구조로, 부품수가 적고 구조도 간단하며 정비성도 좋아 제조비용이 저렴하면서 동력절환이 용이하게 이루어지도록 된 자동차용 프리휠허브를 제공함에 그 목적이 있다.The present invention is devised to solve the above drawbacks, the inner friction member rotated by the rotational force transmitted from the axle shaft transfers the rotational force to the outer friction member operated by the vacuum pressure hub housing coupled with the wheel The purpose of the present invention is to provide a freewheel hub for automobiles, which has a structure that converts from two-wheel drive to four-wheel drive by rotating the motor, so that the number of parts is simple, the structure is simple, the maintenance is good, and the manufacturing cost is low.

상기한 바의 목적을 달성하기 위한 본 고안은, 액슬축으로부터 전달되는 회전력에 의해 스플라인결합되어 회전됨과 더불어 외측에는 경사패드를 갖춘 내측마찰부재와, 이 내측마찰부재의 경사패드에 진공압에 의해 이동되는 다이아프램에 의해 밀착되는 경사패드를 갖춤과 더불어 휠과 결합된 허브하우징과 스플라인결합되어 2륜구동에서 4륜구동으로 변환하는 외측마찰부재와, 상기 내측마찰부재에 끼워짐과 더불어 허브하우징의 내부에 끼워져 진공상태를 이루도록 된 시일부재를 갖춘 구조로 되어 있다.The present invention for achieving the above object is spline-coupled and rotated by the rotational force transmitted from the axle shaft and the inner friction member having an inclined pad on the outside and the inclined pad of the inner friction member by vacuum pressure. It has an inclined pad that is in close contact with the moving diaphragm, and an outer friction member which is splined with the wheel housing coupled with the wheel to convert from two-wheel drive to four-wheel drive, and is fitted to the inner friction member, and inside the hub housing. It is structured with a sealing member fitted in the vacuum state.
이하 본 고안의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안에 따른 프리휠허브의 정단면도로서, 종래 기술을 설명하는 도 1과 동일한 부위에는 동일한 참조부호를 붙이면서 그 설명은 생략한다.Figure 2 is a front sectional view of a freewheel hub according to the present invention, the same reference numerals are attached to the same parts as in Figure 1 illustrating the prior art, the description thereof will be omitted.
본 고안에 따른 프리휠허브는, 액슬축(20)으로부터 전달되는 회전력에 의해 스플라인결합되어 회전됨과 더불어 외측에는 경사패드(110)를 갖춘 내측마찰부재(100)와, 이 내측마찰부재(100)의 경사패드(110)에 진공압에 의해 이동되는 다이아프램(11)에 의해 밀착되는 경사패드(210)를 갖춤과 더불어 휠(30)과 결합된 허브하우징(14)과 스플라인결합되어 2륜구동에서 4륜구동으로 변환하는 외측마찰부재(200)와, 상기 내측마찰부재(100)에 끼워짐과 더불어 허브하우징(14)의 내부에 끼워져 진공상태를 이루도록 된 시일부재(300)를 갖춘 구조로 되어 있다.The freewheel hub according to the present invention is splined by the rotational force transmitted from the axle shaft 20 and rotated and the inner friction member 100 having an inclined pad 110 on the outside and the inner friction member 100 The inclined pad 110 is inclined by the diaphragm 11 which is moved by the vacuum pressure, and is splined with the hub housing 14 coupled with the wheel 30. The outer friction member 200 is converted into a wheel drive, and the seal member 300 is fitted to the inner friction member 100 and inserted into the hub housing 14 to achieve a vacuum state.
다음에는 본 고안의 구성에 따른 작용과 효과에 대해 설명한다.Next will be described the operation and effect according to the configuration of the present invention.
따라서 도시되지 않은 진공탱크에서 발생된 진공상태가 솔레노이드밸브를 매개로 상기 액슬축(20)를 통해 다이아프램(11)을 휠(30)쪽으로 이동시키면, 이 다이아프램(11)에 의해 외측마찰부재(200)가 이동되어 경사패드(210)이 내측마찰부재(100)의 경사패드(110)과 밀착됨으로써 액슬축(20)의 회전력이 내측마찰부재(100) → 외측마찰부재(200) → 허브하우징(14) → 휠(30)로 전달되어 2륜구동에서 4륜구동으로 전환되게 된다.Therefore, when the vacuum generated in the vacuum tank (not shown) moves the diaphragm 11 toward the wheel 30 through the axle shaft 20 via the solenoid valve, the outer friction member is caused by the diaphragm 11. (200) is moved so that the inclined pad 210 is in close contact with the inclined pad 110 of the inner friction member 100, the rotational force of the axle shaft 20 is the inner friction member 100 → outer friction member 200 → hub The housing 14 is transferred to the wheel 30 so as to switch from two-wheel drive to four-wheel drive.
또한 진공상태를 해제하면 상기 내측마찰부재(100)와 외측마찰부재(200)의 마찰력이 해제되어 액슬축(20)의 회전력을 휠(30)에 전달할 수 없으므로 4륜구동에서 2륜구동으로 변환되게 된다.In addition, when the vacuum is released, the frictional force between the inner friction member 100 and the outer friction member 200 is released, and thus, the rotational force of the axle shaft 20 cannot be transmitted to the wheel 30, so that the four wheel drive is converted into two wheel drive. .
이상 설명한 바와 같이 본 고안에 따른 프리휠허브에 의하면, 2륜구동에서 4륜구동으로 전환시 소음이 발생되지 않음은 물론, 4륜구동에서 2륜구동으로 절환시 각바퀴의 속도차에 의해 절환이 되지 않는 것을 완전히 해소할 수 있다.As described above, according to the freewheel hub according to the present invention, when switching from two-wheel drive to four-wheel drive, noise is not generated, and when switching from four-wheel drive to two-wheel drive is not completely switched by the speed difference of each wheel. I can eliminate it.
또한 부품수가 적고 구조도 간단하며 정비성도 좋아 제조비용이 저렴하면서 동력절환이 용이하게 이루어지는 효과가 있다.In addition, the number of parts is simple, the structure is simple, the maintenance is good, the manufacturing cost is low, and the power can be easily switched.
이상에서 본 고안의 구체적인 일 실시예를 상세히 설명하였으나, 본 고안은 이에 한정되는 것은 아니며, 이 분야의 통상의 지식을 가진 자라면 본 고안의 기술적 사상을 바탕으로 다양한 변경과 수정이 가능할 것이다.Although one specific embodiment of the present invention has been described in detail above, the present invention is not limited thereto, and those skilled in the art may make various changes and modifications based on the technical idea of the present invention.
