Description

차량의 조향 너클에 설치되는 허브 록킹장치Hub locking device installed on the steering knuckle of the vehicle

본 발명은 차량의 조향 너클에 조립된 허브의 록킹장치에 관한 것으로, 특히 허브의 고정을 종래의 캐슬너트에 의한 체결력에 대체하여 너클 스핀들의 선택된 위치에 탄착되는 잠금구를 이용하여 간편하게 허브를 고정시키도록 함과 동시에 브레이크 디스크의 체터링(CHATTERING) 현상을 방지토록 한 차량의 조향 너클에 설치되는 허브 록킹장치에 관한 것이다.The present invention relates to a locking device for a hub assembled to a steering knuckle of a vehicle, and in particular, the hub is simply fixed by using a locking mechanism that is fixed to a selected position of the knuckle spindle by replacing the fixing of the hub with a clamping force by a conventional castle nut. And a hub locking device installed at a steering knuckle of a vehicle to prevent chattering of the brake disc.

일반적으로 차량의 조향너클에는 바퀴가 장착되어 있으며 자동차 앞부분의 하중이나 노면에서 받는 충격을 지지함과 동시에 킹핀을 중심으로 회전하여 조향작용을 하게 되어 있다.In general, the steering knuckle of the vehicle is equipped with wheels, and it supports steering by the load on the front part of the vehicle or the impact from the road, and rotates around the kingpin to steer.

종래는 도 1에서와 같이 너클(10)의 너클스핀들(11)에 내측 베어링(12)과 외측베어링(13)이 삽입되어 있고, 이를 베어링(12,13)의 외륜에 허브(20)가 삽입 조립되고, 이 허브(20)에 브레이크 디스크(30)가 체결수단으로 조립되어 있고, 상기 너클 스핀들(11)에는 캐슬 너트(40)가 나사 결합되어 상기 훨 허브(20)의 이탈을 방지하게 되어 있고, 상기 캐슬 너트(40)에는 분할핀(50)이 삽입되어 너클 스핀들(11)에서 캐슬 너트(40)의 풀림이 방지되도록 되어 있다.Conventionally, the inner bearing 12 and the outer bearing 13 are inserted into the knuckle spindles 11 of the knuckle 10 as shown in FIG. 1, and the hub 20 is inserted into the outer rings of the bearings 12 and 13. The brake disk 30 is assembled to the hub 20 as a fastening means, and the castle nut 40 is screwed to the knuckle spindle 11 to prevent the hub hub 20 from being separated. In addition, a split pin 50 is inserted into the castle nut 40 to prevent loosening of the castle nut 40 from the knuckle spindle 11.

이같은 상태에서 차량이 주행하게 되면 허브(20)와 일체로 브레이크 디스크(30) 및 차륜(60)이 너클스핀들(11)에서 회전하게 된다.When the vehicle travels in this state, the brake disc 30 and the wheel 60 rotate in the knuckle spindles 11 integrally with the hub 20.

그런데 여기서 캐슬 너트(40)의 조임상태 불량 등으로 오작업이 이루어질 경우 허브(20)와 브레이크 디스크(30)의 유동이 발생한다.By the way, when the misoperation is made due to poor tightening state of the castle nut 40, the flow of the hub 20 and the brake disk 30 occurs.

이같이 허브(20)와 브레이크 디스크(30)의 유동발생기 브레이크 폐달을 밟아 제동력을 발생시키게 되면 브레이크 디스크(30)의 마찰면적에 변화가 생겨 제동력 저하를 가져올 수 있다.In this way, when the braking force is generated by stepping on the flow generator brake closing of the hub 20 and the brake disc 30, the friction area of the brake disc 30 may be changed, resulting in a decrease in the braking force.

또한, 허브(20)에 장착되는 차륜의 흔들림으로 채터링(CHATTERING) 현상이 발생하고, 주행상태가 불안정해지는 상황을 초래할 수 있다.In addition, the chattering phenomenon may occur due to the shaking of the wheels mounted on the hub 20, and the driving state may become unstable.

더욱이 캐슬 너트(40)가 나사결합식으로 조립되기 때문에 작업성이 떨어지는 단점이 있다.Furthermore, since the castle nut 40 is assembled by screwing, workability is inferior.

본 발명은 상기와 같은 제반적인 사정을 감안하여 안출된 것으로, 허브의 고정을 종래의 캐슬너트에 의한 체결력에 대체하여 너클 스핀들의 선택된 위치에 탄착되는 잠금구를 이용하여 간편하게 허브를 고정시키도록 함과 동시에 브레이크 디스크의 체터링(CHATTERING) 현상을 방지토록 한 차량의 조향 너클에 설치되는 허브록킹장치를 제공함에 그 목적이 있다.The present invention has been devised in view of the above-mentioned circumstances, and the hub can be easily fixed by using a locking mechanism secured to a selected position of the knuckle spindle in place of the fastening of the hub by a conventional castle nut. In addition, it is an object of the present invention to provide a hub locking device installed on the steering knuckle of the vehicle to prevent the chattering (CHATTERING) phenomenon of the brake disc.

상기의 목적을 달성하기 위한 본 발명의 구체적인 수단은, 차량용 조향 너클(10)의 너클 스핀들(11)에 회전지지되게 장착된 허브(20)를 고정시키기 위한 장치에 있어서, 상기 너클 스핀들(11)의 원주방향에 대해 소정 간격으로 대향된 한쌍의 삽입구멍(11a)을 여러개소에 관통 형성하고, 이들 삽입구멍(11a)의 사이에 각각의 탄착흠(11b)을 형성하고, 상기 삽입구멍(11a) 및 탄착흠(11b)에 삽입되어 위치결정되는 대향된 돌출부(111)와 위치결정편(112)을 형성한 다수쌍의 잠금몸체(113)를 구비하고, 이들 잠금몸체(100)는 인장스프링(110)에 의해 서로 원주방향으로 잡아 당기도록 구성한 잠금구(100)로 이루어진 것을 특징으로 한다.A specific means of the present invention for achieving the above object, in the device for fixing the hub 20 is rotatably mounted on the knuckle spindle 11 of the vehicle steering knuckle 10, the knuckle spindle (11) A pair of insertion holes 11a opposed to the circumferential direction at predetermined intervals are formed through the plurality of insertion holes 11b between the insertion holes 11a, and the insertion holes 11a are formed. ) And a plurality of pairs of locking bodies 113 formed by opposing protrusions 111 and positioning pieces 112 inserted and positioned in the impact flaw 11b, and these locking bodies 100 are tension springs.

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

도 2,3,4 에 도시된 바와 같이 차량용 조향 너클(10)의 너클 스핀들(11)에 회전지지되게 장착된 허브(20)를 고정시키기 위한 장치에 있어서, 상기 너클 스핀들(11)의 원부방향에 대해 소정 간격으로 대향된 한쌍의 삽입구멍(11a)을 여러개소에 관통 형성하고, 이들 삽입구멍(11a)의 사이에 각각의 탄착홈(11b)을 형성하고, 상기 삽입구멍(11a) 및 탄착홈(11b)에 삽입되어 위치결정되는 대향된 돌출부(111)와 위치결정편(112)을 형성한 다수쌍의 잠금몸체(113)를 구비하고, 이들 잠금몸체(113)는 인장스프링(110)에 의해 서로 원주방향으로 잡아당기도록 구성한 잠금구(100)로 이루어져 있다.2, 3, 4, in the arrangement for securing the hub 20 rotatably mounted to the knuckle spindle 11 of the vehicle steering knuckle 10, the distal direction of the knuckle spindle 11 A pair of insertion holes 11a opposed to each other at predetermined intervals are formed therethrough, and respective impact grooves 11b are formed between the insertion holes 11a, and the insertion holes 11a and the impact force are formed. A plurality of pairs of locking bodies 113 formed with opposed protrusions 111 and positioning pieces 112 inserted and positioned in the grooves 11b, and these locking bodies 113 are tension springs 110; It consists of a locking mechanism (100) configured to pull each other in the circumferential direction.

즉, 상기 잠금구(100)는 본 실시예에서 4개의 잠금몸체(100)로 구성되서 각각의 인장스프링(110)에 의해 원주방향으로 구속되어 있다.That is, the locking device 100 is composed of four locking bodies 100 in the present embodiment is constrained in the circumferential direction by each tension spring 110.

따라서 잠금구(100)가 너클 스핀들(11)에 끼워지기 전에는 인장스프링(110)의 탄성력에 의해 잠금구(100)의 내측 직경은 적어도 너클 스핀들(11)의 직경보다 작게 설정되어 있어야 한다.Therefore, before the locking device 100 is fitted to the knuckle spindle 11, the inner diameter of the locking device 100 should be set at least smaller than the diameter of the knuckle spindle 11 by the elastic force of the tension spring 110.

이와 같이 구성된 본 실시예의 작용을 설명한다.The operation of this embodiment configured as described above will be described.

먼저, 너클(10)의 너클 스핀들(11)에 베어링(12)을 삽입하고, 이 베어링(12)의 외륜에 허브(20)를 조립한다.First, the bearing 12 is inserted into the knuckle spindle 11 of the knuckle 10, and the hub 20 is assembled to the outer ring of the bearing 12.

다음, 잠금구(100)의 각 잠금몸체(113)를 외측의 직경방향으로 잡아당기게 되면 잠금몸체(1130는 인장 스프링(110)을 신장시키면서 잠금구(100)의 내측 직경이 확장된다.Next, when each locking body 113 of the lock 100 is pulled in the outer diameter direction, the lock body 1130 extends the inner diameter of the lock 100 while extending the tension spring 110.

이렇게 잠금구(100)의 내경을 확장시켜 너클 스핀들(11)에 집어넣은 후 너클 스핀들(11)의 탄착홈(11b)에 위치시키고, 다시 잠금몸체(113)의 직경을 변화시키기 위해 가해진 힘을 제거하게 되면, 인장스프링(110)의 복원력에 의해 각 잠금몸체(113)들은 너클 스핀들(11)의 중심축선상을 향에 이동하여 너클 스핀들(11)에 밀착된다.In this way, the inner diameter of the lock 100 is expanded and inserted into the knuckle spindle 11, and then placed in the impact groove 11b of the knuckle spindle 11, and the force applied to change the diameter of the lock body 113 is again applied. When it is removed, the locking bodies 113 are moved toward the center axis of the knuckle spindle 11 by the restoring force of the tension spring 110 to be in close contact with the knuckle spindle 11.

이로 인해 상기 너클 스핀들(11)의 삽입구멍(11a) 및 탄착홈(11b)에는 잠금몸체(113)의 돌출부(111)와 위치결정편(112)이 각각 끼워맞춤되어 허브(20)의 위치결정이 이루어진다.As a result, the protrusion 111 and the positioning piece 112 of the locking body 113 are fitted into the insertion hole 11a and the contact groove 11b of the knuckle spindle 11 to position the hub 20. This is done.

이렇게하여 본 발명의 잠금구(100)가 너클(10)의 너클 스핀들(11)에 조립되게 되면, 잠금구(100)의 일축면이 외측 베어링(13)으로 밀착되고, 이 결과 허브(20)가 베어링(12)에 완전히 삽입되어 장착이 이루어진다.In this way, when the lock 100 of the present invention is assembled to the knuckle spindle 11 of the knuckle 10, the uniaxial surface of the lock 100 is in close contact with the outer bearing 13, and as a result the hub 20 Is fully inserted into the bearing 12 to mount.

따라서 종래와 같이 캐슬너트를 사용할 때 체결력의 불량 등으로 발생되는 허브(20)의 오조립을 방지할 수 있다.Therefore, it is possible to prevent the misassembly of the hub 20 caused by a poor fastening force when using the castle nut as in the prior art.

또 이같이 허브(20)의 오조립을 방지할 수 있으므로 허브(20)에 장착되는 브레이크 디스크(30)의 유동을 없애서 제동력 저하는 발생되지 않는다. 따라서 주행상태의 안전성을 향상시킬 수 있다.In addition, since the misassembly of the hub 20 can be prevented in this way, the braking force is not lowered by eliminating the flow of the brake disc 30 mounted on the hub 20. Therefore, the safety of the driving state can be improved.

그리고 상기 잠금구(100)는 너클 스핀들(11)에 삽입, 끼워맞춤되는 것으로 조립이 간단히 완료됨으로 조립 작업성이 간편하다.In addition, the locking tool 100 is inserted into the knuckle spindle 11 and fitted to the assembly.

상술한 바와 같이 본 발명에 의하면 너클의 너클 스핀들에 조립되는 허브의 고정을 캐슬너트가 아닌 간편하게 착탈가능한 잠금구에 의해 이루어지도록 함으로써 조립작업성의 향상은 물론 주행 안전성의 신뢰를 가져올 수 있는 장점이 있다.As described above, according to the present invention, as the hub is assembled to the knuckle spindle of the knuckle, it is possible to improve the assembly workability and bring about the reliability of the driving safety by making the lock nut easily detachable instead of the castle nut. .
