Abstract

PURPOSE: A hubcap of a wheel bearing for a vehicle is provided to operate the wheel bearing quietly and improve the durability by surface-contacting the wheel hub to the hubcap against processing errors and deformation in assembling with forming the vulcanizing rubber forming part in the flange of the hubcap. CONSTITUTION: A vulcanizing part(5) is placed circumferentially in a flange part(3) of a hubcap(1) and formed by curing rubber surrounding the flange part. The rubber is vulcanized in the flange part of the hubcap for sealing efficiently. The U-shaped section is formed in the vulcanizing part to surround the flange part completely. The flange part of the hubcap is bonded firmly to the vulcanizing part by securing the bonding area. A semicircular section protruded end(9) is formed circumferentially in the vulcanizing part for a wheel hub. Sealing efficiency between the hubcap and the wheel hub is improved by contacting the semicircular section protruded end to the wheel hub with inserting the hubcap to the wheel hub. The wheel bearing is operated quietly by restricting inflow of moisture or foreign matters to the wheel bearing.

차량의 휠 베어링 허브 캡{wheel bearing hub cap of a vehicle}Wheel bearing hub cap of a vehicle

본 발명은 차량의 비구동륜에 사용되는 휠 베어링에 이물질이 침입하는 것을 방지하도록 휠 허브에 장착되는 허브 캡에 관한 것으로서, 보다 향상된 실링 성능을 확보하기 위한 기술에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hub cap mounted to a wheel hub to prevent foreign matter from entering a wheel bearing used for a non-drive wheel of a vehicle, and more particularly, to a technique for securing improved sealing performance.

차량의 비구동륜은 차축에 대하여 휠 허브가 휠 베어링에 의해 지지되어 차량의 주행에 따라 종동되도록 되어 있는바, 도 1에는 상기 휠 베어링(100)에 외부로부터 이물질이 침입하는 것을 방지하도록 하기 위하여 휠 허브(102)에 허브 캡(104)을 압입하여 장착한 상태가 도시되어 있다.In the non-drive wheel of the vehicle, the wheel hub is supported by the wheel bearing with respect to the axle, and is driven according to the driving of the vehicle. In FIG. 1, the wheel to prevent foreign matter from entering the wheel bearing 100 from the outside. The state where the hub cap 104 is press-fitted to the hub 102 is shown.

즉, 상기 허브 캡(104)은 외부로부터 습기나 먼지가 상기 휠 베어링(100)에 침투하지 못하도록 하여, 상기 휠 베어링(100)이 휠 허브(102)와 차축(106) 사이에서 안정적으로 정숙한 작동상태를 지속시키도록 하기 위한 것이다.That is, the hub cap 104 prevents moisture or dust from penetrating the wheel bearing 100 from the outside, so that the wheel bearing 100 is quietly stable between the wheel hub 102 and the axle 106. This is to keep the operating state.

따라서, 상기한 바와 같은 허브 캡(104)은 상기 휠 허브(102)와의 접촉부위에서 긴밀한 실링(SEALING) 성능이 가장 중요한데, 도 2에 도시된 바와 같이 상기 허브 캡(104)에 마련된 플랜지부(106)는 단순히 강판을 절곡하여 형성된 형상이어서, 허브 캡(104)의 가공정도 및 조립시의 변형 등에 의해 상기 휠 허브(102)와의 면접촉 상태에 한계가 있어서, 이 부위를 통하여 수분 등과 같이 이물질이 침투하여 휠 베어링(100)에 손상을 주어 소음이 발생하도록 함과 아울러 그 수명을 단축시키는 문제점이 있다.Accordingly, the hub cap 104 as described above is most important in close sealing performance at the contact with the wheel hub 102, the flange portion 106 provided in the hub cap 104 as shown in FIG. ) Is simply a shape formed by bending a steel plate, there is a limit in the surface contact state with the wheel hub 102 due to the processing degree of the hub cap 104, deformation during assembly, etc., foreign matter such as moisture through this portion There is a problem to penetrate and damage the wheel bearing 100 to generate noise and shorten its life.

이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 부품의 가공오차 및 조립시 변형 등의 경우에도 휠 허브와 허브 캡의 접촉부위에서 강한 면접촉 상태를 형성할 수 있도록 함으로써, 휠 베어링의 정숙한 운전상태와 내구성을 지속적으로 유지하도록 할 수 있는 차량의 휠 베어링 허브 캡을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, by making a strong surface contact state at the contact portion of the wheel hub and the hub cap even in the case of machining errors and deformation during assembly, wheel bearing The object of the present invention is to provide a hub bearing hub cap of a vehicle capable of continuously maintaining a quiet driving condition and durability.

상기한 바와 같은 목적을 달성하기 위한 본 발명 차량의 휠 베어링 허브 캡은 허브 캡의 플랜지부에는 원주방향을 따라 상기 플랜지부를 감싸는 러버가 가류 성형된 가류성형부를 구비한 것을 특징으로 한다.The wheel bearing hub cap of the present invention for achieving the object as described above is characterized in that the flange portion of the hub cap is provided with a vulcanization molding unit in which the rubber that wraps the flange portion in the circumferential direction.

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

도 3과 도 4는 본 발명에 따른 휠 베어링 허브 캡의 설치상태 및 상세구조를 도시한 것으로서, 허브 캡(1)의 플랜지부(3)에 원주방향을 따라 상기 플랜지부(3)를 감싸는 러버가 가류 성형된 가류성형부(5)가 구비되어 있는 점이 종래 기술과 다르다.3 and 4 show the installation state and the detailed structure of the wheel bearing hub cap according to the present invention, the rubber surrounding the flange portion 3 in the circumferential direction to the flange portion 3 of the hub cap (1) It is different from the prior art that the vulcanization molding part 5 which was vulcanized and molded was provided.

즉, 상기 허브 캡(1)의 플랜지부(3)에 실링 성능을 향상시키도록 하기 위하여 러버를 가류 성형한 것인데, 이때 상기 가류성형부(5)는 상기 플랜지부(3)를 감싸도록 형성되어 그 형상이 “U”자형 단면을 가지도록 되어 있다.That is, the rubber is vulcanized in order to improve the sealing performance in the flange portion 3 of the hub cap 1, wherein the vulcanization molding portion 5 is formed to surround the flange portion (3) The shape is intended to have a "U" cross section.

이는 상기 가류성형부(5)가 상기 플랜지부(3)를 외측으로부터 완전히 감싸도록 하여, 상기 허브 캡(1)의 플랜지부(3)와 가류성형부(5)의 접합면적을 충분히 확보하여 안정적인 접합상태를 확보하기 위한 것이다.This ensures that the vulcanization molding part 5 completely covers the flange part 3 from the outside, and sufficiently secures the joint area of the flange part 3 and the vulcanization molding part 5 of the hub cap 1 so as to be stable. It is to secure the bonding state.

한편, 상기 가류성형부(5)는 휠 허브(7)를 향한 면에 원주방향을 따라 반원형 단면의 돌출단(9)이 형성되어 휠 허브(7)와의 실링 성능을 극대화하도록 하였다.On the other hand, the vulcanization molding part 5 has a projecting end 9 of a semi-circular cross section along the circumferential direction on the surface facing the wheel hub 7 to maximize the sealing performance with the wheel hub (7).

즉, 상기한 바와 같이 형성된 허브 캡(1)을 휠 허브(7)에 압입하여 장착하면, 상기 허브 캡(1)을 압입하여 장착할 때, 상기 반원형단면의 돌출단(9)이 상기 휠 허브(7)에 밀착하면서 소정량 변형된 상태로 결합이 완료되게 되는데, 이 상태에서는 상기 러버 소재의 돌출단(9)이 복원되려고 하는 고유의 힘이 상기 휠 허브(7)와의 실링 상태를 더욱 확실하게 유지하도록 하는 것이다.That is, when the hub cap 1 formed as described above is press-fitted to the wheel hub 7, when the hub cap 1 is press-fitted and mounted, the protruding end 9 of the semi-circular cross section is the wheel hub. The coupling is completed in a state in which a predetermined amount is deformed while being in close contact with (7). In this state, the inherent force that the projecting end 9 of the rubber material is to be restored makes the sealing state with the wheel hub 7 more certain. To keep it.

따라서, 상기한 바와 같은 허브 캡(1)은 휠 허브(7)와 완벽한 실링 상태를 구현하여 내부의 휠 베어링(11)으로 수분이나 기타의 이물질이 침투할 수 없도록 함으로써, 휠베어링(11)의 정숙한 작동성을 지속적으로 유지시키게 된다.Therefore, the hub cap 1 as described above implements a perfect sealing state with the wheel hub 7 to prevent moisture or other foreign matter from penetrating into the wheel bearing 11 therein, thereby preventing the Quiet operability is maintained continuously.

이상과 같이 본 발명에 의하면, 허브 캡의 플랜지부에 러버 재질의 가류성형부를 구비함으로써, 부품의 가공오차 및 조립시 변형 등의 경우에도 휠 허브와 허브 캡의 접촉부위에서 강한 면접촉 상태를 형성할 수 있도록 함으로써, 휠 베어링의 정숙한 운전상태와 내구성을 지속적으로 유지하도록 할 수 있다.As described above, according to the present invention, by providing a rubber-like vulcanization portion at the flange portion of the hub cap, a strong surface contact state can be formed at the contact portion between the wheel hub and the hub cap even in the case of machining errors and deformation during assembly. By doing so, it is possible to continuously maintain the quiet driving state and durability of the wheel bearing.
