본 고안은 등속조인트용 부압방지부트에 관한 것으로서, 더욱 상세히는 등속조인트용 부트를 개선하여 부압의 발생을 방지하기 위한 것이다.The present invention relates to a negative pressure preventing boot for a constant velocity joint, and more particularly, to prevent the occurrence of negative pressure by improving the boot for the constant velocity joint.

자동차의 등속조인트부에는 고무재의 부트(boot)가 사용되어 완충효과를 도모하고 외부환경으로부터 내부 부재를 보호하는 역활을 수행하면서 동적인 저항과 운동을 흡수도록 되어있다.A rubber boot is used for the constant velocity joint of the automobile to absorb the dynamic resistance and movement while promoting a cushioning effect and protecting the inner member from the external environment.

그러나, 종래의 형상과 구조의 부트는 차량이 주행할 때에 조인트의 발열 및 엔진등의 기구에서의 발열과 고속회전에 의하여 부트의 팽창이 이루어지고, 고무의 통기성이 높아져 조인트 내부의 공기가 밖으로 빠져나가고,However, the boot of the conventional shape and structure is the expansion of the boot by the heat generated by the joint and the heat generated by the mechanism such as the engine and high-speed rotation when the vehicle is running, the air permeability of the rubber is increased, the air inside the joint is leaked out Going out,

야간 정차시에는 기온이 떨어지고 발열부가 없어 통기성이 나빠져 외부공기가 조인트내부로 유입되지 못하는 소위 부압(負壓)이 걸리게 되는 것이다.When stopping at night, the temperature drops and there is no heat-generating part, which results in poor ventilation, so that negative air cannot be introduced into the joint.

이러한 현상이 반복적으로 이루어지면 부트내부의 부압으로 인하여 부트가 쭈그러드는 현상이 일어나고 심지어는 부트가 찢어지는 일이 발생하기도 한다.If this happens repeatedly, the boot will collapse due to negative pressure inside the boot, and even the boot may tear.

이러한 문제점을 해결하기 위하여 종래에는 부트자체에 미세한 소공을 레이저빔으로 형성하거나 통기성이 양호한 실리콘 고무를 사용하지만 그 제조원가가 상당하여 한정적으로 사용되고 있다.In order to solve this problem, conventionally, fine pores are formed in the boot itself with a laser beam or silicon rubber having good air permeability is used.

상기와 같은 문제점을 감안하여 본고안의 등속조인트용 부압방지부트는 개선된 구성과 형상을 구비하는 부트를 제공하는 것을 목적으로 한다.In view of the above problems, the negative pressure preventing boot for the constant velocity joint of the present disclosure aims to provide a boot having an improved configuration and shape.

이하의 부수된 도면과 함께 본고안의 등속조인트용 부압방지부트를 더욱 상세하게 설명한다.The negative pressure preventing boot for the constant velocity joint of the present invention together with the accompanying drawings will be described in more detail.

제1도는 본고안의 등속조인트용 부압방지부트를 도시하는 정면도, 제2도는 제1도의 측단면도로서 함께 설명한다.FIG. 1 is a front view showing a negative pressure preventing boot for a constant velocity joint of the present invention, and FIG. 2 is a side cross-sectional view of FIG.

본고안의 등속조인트용 부압방지부트는 통상적인 탄성소재로서 제조되는 부트(1)의 양쪽의 대경부(2)와 소경부(3)를 가지게 되고, 소경부(3)는 조인트축(5)에 체결된다.The negative pressure prevention boots for constant velocity joints in this disclosure have large diameter portions 2 and small diameter portions 3 on both sides of the boot 1 made of a conventional elastic material, and the small diameter portions 3 are provided on the joint shaft 5. Is fastened.

본고안의 등속조인트용 부압방지부트는 소경부(3)의 내측원주벽면을 따라서 축방향으로 다수개(도면에서는 4개)의 그루우브(groove)(4)가 형성되어 있다.The negative pressure preventing boot for the constant velocity joint of the present invention is provided with a plurality of grooves 4 in the axial direction along the inner circumferential wall surface of the small diameter portion 3.

상기의 그루우부(4)는 조인트축(4)에 접속하여 조립될 때에 일종의 통기공의 역활을 수행함으로서 상기의 문제는 해결되는 것이다.The above problem is solved by performing the role of a kind of ventilation hole when the groove portion 4 is connected to the joint shaft 4 and assembled.

상기와 같은 구성의 본고안의 등속조인트용 부압방지부트는 부트와 외부환경과의 통기성을 양호하게 하여 종래의 부압문제를 완전히 일소할 수 있는 유용한 고안인 것이다.The negative pressure preventing boot for the constant velocity joint of the present disclosure having the above configuration is a useful design that can completely eliminate the conventional negative pressure problem by improving the breathability between the boot and the external environment.
