본 고안은 자동차의 드라이브 액슬 샤프트에 관한 것으로, 더 상세히는 부트로 감싼 등속 조인트에 그리이스를 주입할 수 있도록 한 자동차의 드라이브 액슬 샤프트에 관한 것이다.The present invention relates to a drive axle shaft of a motor vehicle, and more particularly, to a drive axle shaft of a motor vehicle capable of injecting grease into a constant velocity joint wrapped with a boot.

자동차의 드라이브 액슬 샤프트는 바퀴를 통하여 차의 무게를 지지하는 부분이며, 엔진에서 발생한 동력을 전달하기도 한다.The drive axle shaft of the vehicle is a part that supports the weight of the vehicle through the wheels, and also transmits the power generated by the engine.

제1도는 일반적인 자동차의 드라이브 액슬 샤프트의 조인트를 보인 단면도이다.1 is a cross-sectional view showing a joint of a drive axle shaft of a general automobile.

제1도에 도시한 바와같이, 드라이브 액슬 샤프트는 구동축(10)과 바깥 조인트축(20)이 등속 조인트(30)로 연결되며, 너클(40), 액슬 허브(50), 허브 베어링(60) 등으로 휠(W)에 결합되어 있다. 그리고 등속 조인트(30)를 보호하기 위하여 그리이스를 봉입하고 부우트(70)를 설치하였다.As shown in FIG. 1, the drive axle shaft is connected to the drive shaft 10 and the outer joint shaft 20 by the constant velocity joint 30, the knuckle 40, the axle hub 50, the hub bearing 60 It is coupled to the wheel W by the back. And in order to protect the constant velocity joint 30, grease was enclosed and the booth 70 was installed.

그런데, 종래에는 등속 조인트(30)에 있는 그리이스가 누출되면 주입이 불가하여 드라이브 액슬 샤프트의 교환시에 하거나, 부트의 절개하고 그리이스를 봉입한 다음 부트를 교환하여야만 했다. 따라서 그리이스의 주입에 따른 번거로움이 크며, 그리이스의 주입을 적시에 하지 않고 차량을 운행하여 드라이브 액슬 샤프트의 손상을 초래하였다.However, conventionally, when the grease in the constant velocity joint 30 leaks, injection is impossible, so that the drive axle shaft has to be replaced or the boot has been cut and the grease has been sealed and the boot has to be replaced. Therefore, the hassle caused by the injection of the grease is great, driving the vehicle without timely injection of the grease caused damage to the drive axle shaft.

이러한 점을 감안한 본 고안의 목적은 등속 조인트(30)에 그리이스를 주입할 수 있는 구조를 갖는 자동차의 드라이브 액슬 샤프트를 제공하는데 있다.The purpose of the present invention in view of this point is to provide a drive axle shaft of a vehicle having a structure capable of injecting grease into the constant velocity joint 30.

상술한 목적을 달성하기 위하여, 본 고안은 구동축과 바깥 조인트축이 등속 조인트로 연결되고, 상기 바깥 조인트축은 너클, 액슬 허브, 허브 베어링 등으로 휠에 결합되며, 상기 등속 조인트를 보호하기 위하여 그리이스를 봉입하고 부우트를 설치한 자동차의 드라이브 액슬 샤프트에 있어서, 상기 바깥 조인트 축에 그리이스 주입용 니플(80)(nipple)을 설치하여 상기 등속 조인트에 그리이스를 주입할 수 있도록 한다.In order to achieve the above object, the present invention is a drive shaft and the outer joint shaft is connected to the constant velocity joint, the outer joint shaft is coupled to the wheel by knuckles, axle hub, hub bearings, etc., to protect the constant velocity joint grease In a drive axle shaft of a vehicle that is sealed and mounted with a booth, a grease injection nipple (80) is installed on the outer joint shaft so that grease can be injected into the constant velocity joint.

이하, 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하며, 종래와 동일한 부분에 대하여는 동일한 부호를 부여하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, and like reference numerals refer to like elements.

제2도는 본 고안에 따른 자동차의 드라이브 액슬 샤프트의 조인트를 보인 단면도이다.2 is a cross-sectional view showing a joint of a drive axle shaft of a vehicle according to the present invention.

제2도에 도시한 바와같이, 본 고안에 따른 드라이브 액슬 샤프트는 구동축(10)과 바깥 조인트축(20)이 등속조인트로 연결되고, 상기 바깥 조인트축(20)은 너클(40), 액슬 허브(50), 허브 베어링(60) 등으로 휠(W)에 결합되며, 상기 등속 조인트(30)를 보호하기 위하여 그리이스를 봉입하고 부우트(70)를 설치한 것에 있어서, 상기 바깥 조인트 축에 그리이스 주입용 니플(80)(nipple)을 설치하여 등속 조인트(30)에 그리이스를 주입할 수 있도록 하였다.As shown in Figure 2, the drive axle shaft according to the present invention is the drive shaft 10 and the outer joint shaft 20 is connected by a constant velocity joint, the outer joint shaft 20 is knuckle 40, axle hub 50, which is coupled to the wheel W by the hub bearing 60, etc., in which the grease is enclosed in order to protect the constant velocity joint 30 and the booth 70 is installed, the grease is formed on the outer joint shaft. An injection nipple 80 (nipple) was installed to allow grease to be injected into the constant velocity joint 30.

상기한 니플(80)은 바깥 조인트축(20)에 길이방향으로 그리이스 주입공(81)을 형성하여 휠(W)의 바깥쪽에서 그리이스를 주입할 수 있도록 하고 이물질이 들어가지 않도록 그리이스 주입공(81)의 입구에 캡(82)을 마련한 것이다.The nipple 80 forms a grease injection hole 81 in the longitudinal direction on the outer joint shaft 20 to allow grease to be injected from the outside of the wheel W, and the grease injection hole 81 to prevent foreign substances from entering. The cap 82 is provided in the entrance.

상기한 캡(82)은 니플(80)에 나사체결식으로 결합할 수 있도록 하는 것이 바람직하다.The cap 82 is preferably to be screwed to the nipple (80).

이와같이, 니플(80)이 설치된 본 고안은 등속 조인트(30)에 봉입된 그리이스가 누출되어 그리이스의 보충이 필요하면, 휠(W)의 바깥쪽에서 캡(82)을 열고 적당량의 그리이스를 그리이스 주입공(81)을 통하여 주입시키면 된다. 이때 그리이스 주입공(81)을 통하여 주입되는 그리이스는 부우트(70)의 내부로 유입되어 조인트를 윤활하게 된다.As such, the present invention in which the nipple 80 is installed has a grease enclosed in the constant velocity joint 30 so that the grease needs to be replenished. What is necessary is just to inject through (81). At this time, the grease injected through the grease injection hole 81 is introduced into the booth 70 to lubricate the joint.

상술한 바와같이, 본 고안에 따른 자동차의 드라이브 액슬 샤프트는 등속 조인트(30)에 그리이스를 주입할 수 있도록 바깥쪽 조인트 축에 니플(80)을 설치 한 것으로, 그리이스의 보충이 가능하므로 제품의 손상을 방지하고 자동차의 운행상태를 지속시킬 수 있는 효과가 있다.As described above, the drive axle shaft of the vehicle according to the present invention is to install the nipple (80) on the outer joint shaft to inject the grease into the constant velocity joint 30, the grease can be replenished, damage the product It is effective in preventing and maintaining the driving state of the car.
