본 발명은 유체 밀폐용 실링부재에 관한 것으로, 더욱 상세하게는 유압브레이크 시스템 등에 채용되는 피스톤부재와 실린더부재처럼 상호 진퇴운동하는 2개의 부재 사이로 유체가 이동하는 것을 방지하도록 설치되는 유체 밀폐용 실링부재에 관한 것이다.The present invention relates to a fluid sealing seal member, and more particularly, to a fluid sealing seal member installed to prevent fluid from moving between two piston members, such as a cylinder member and a cylinder member, which are employed in a hydraulic brake system. It is about.

일반적으로 유압브레이크 시스템 등에 채용되는 피스톤부재의 외면에는 실린 더부재의 내면과 피스톤부재의 외면 사이로 유체가 이동하는 것을 방지하기 위해 유체 밀폐용 실링부재가 설치되는데, 이때 상기 실린더부재는 외측에 마련되는 외측부재를 형성하게 되고, 상기 피스톤부재는 외측부재 내부에서 진퇴운동하며 유체를 압축하는 내측부재를 형성하며, 상기 유체 밀폐용 실링부재는 피스톤의 진퇴동작시 피스톤부재과 실린더부재 사이로 오일이 이동하는 것을 방지하도록 내측부재와 외측부재 사이에 설치된다.In general, a fluid sealing seal member is installed on an outer surface of a piston member that is used in a hydraulic brake system to prevent fluid from moving between an inner surface of the cylinder member and an outer surface of the piston member. An outer member is formed, and the piston member moves in and out of the outer member to form an inner member that compresses the fluid. The fluid sealing member is configured to move oil between the piston member and the cylinder member during the piston retracting operation. It is installed between the inner member and the outer member to prevent.

도 1에 도시된 바와 같이, 내측부재(1)와 외측부재(2) 사이로 유체가 이동하는 것을 방지하도록 내측부재(1)와 외측부재(2) 사이에 설치되는 종래의 유체 밀폐용 실링부재(3)는 통상 탄성재질의 링형상으로 마련되고, 실링부재(3)를 수용하도록 내측부재(1)의 외면에 형성된 수용홈(1a)에 장착된 상태에서 내측부재(1)와 함께 진퇴하면서 유체 밀폐 기능을 수행한다.As shown in FIG. 1, a conventional fluid sealing member installed between the inner member 1 and the outer member 2 to prevent fluid from moving between the inner member 1 and the outer member 2 ( 3) is generally provided in a ring shape of an elastic material, while the fluid is retracted with the inner member 1 in a state of being mounted in the receiving groove (1a) formed on the outer surface of the inner member 1 to accommodate the sealing member (3) Perform a sealing function.

그리고 이러한 실링부재(3)는 내측부재(1)의 외면과 외측부재(2)의 내면 사이에 어느 정도 가압된 상태로 설치되어 그 탄성복원력을 통해 유체를 밀폐시키도록 마련되므로, 이 실링부재(3)의 유체 밀폐 성능은 실링부재(3)가 외측부재(2)를 수직방향으로 미는 힘에 비례하게 되고, 이러한 힘은 실링부재(3)를 형성하는 재질의 탄성계수에 의해 크게 좌우된다.And since the sealing member 3 is provided in a pressurized state to some extent between the outer surface of the inner member 1 and the inner surface of the outer member 2 to seal the fluid through its elastic restoring force, the sealing member ( The fluid sealing performance of 3) is proportional to the force of the sealing member 3 pushing the outer member 2 in the vertical direction, and this force is largely determined by the elastic modulus of the material forming the sealing member 3.

또 내측부재(1)의 진퇴동작시 외측부재 측 실링부재(3)에는 내측부재(1)의 진퇴방향과 반대방향으로 마찰력이 작용하게 되며, 이러한 마찰력은 실링부재(3)가 외측부재(2)를 미는 힘에 비례하므로 실링부재(3)의 탄성계수가 커질수록 커지게 된다. In addition, the frictional force acts on the outer member side sealing member 3 in a direction opposite to the advancing direction of the inner member 1 when the inner member 1 moves forward and backward, and the frictional force is such that the sealing member 3 is connected to the outer member 2. Since it is proportional to the pushing force, the elastic modulus of the sealing member 3 increases.                         

따라서 이러한 종래 유체 밀폐용 실링부재(3)는 유체 밀폐 성능을 향상시키기 위해 실링부재(3)를 탄성계수가 큰 재질로 형성할 경우 실링부재(3)가 외측부재(2)를 수직방향으로 미는 힘이 커지며 유체밀폐성능은 향상되는 반면 외측부재(2) 측 실링부재(3)에 작용하는 마찰력도 커지게 되며 실링부재(3)가 쉽게 마모되고, 실링부재(3)의 내마모성을 향상시키기 위해 실링부재(3)를 탄성계수가 작은 재질로 형성할 경우에는 반대로 실링부재(3)의 내마모성이 향상되는 반면 실링부재(3)의 유체밀폐성능이 저하되는 문제점이 발생하게 된다. Therefore, in the conventional fluid sealing member 3, the sealing member 3 pushes the outer member 2 in the vertical direction when the sealing member 3 is formed of a material having a large modulus of elasticity to improve fluid sealing performance. The force is increased and the fluid sealing performance is improved while the frictional force acting on the outer member 2 side sealing member 3 is also increased, and the sealing member 3 is easily worn and the wear resistance of the sealing member 3 is improved. When the sealing member 3 is formed of a material having a small modulus of elasticity, the wear resistance of the sealing member 3 is improved while the fluid sealing performance of the sealing member 3 is deteriorated.

본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 유체 밀폐 성능의 저하 없이 내마모성을 향상시킬 수 있음은 물론 내마모성의 저하 없이 유체 밀폐 성능을 향상시킬 수 있도록 마련된 유체 밀폐용 실링부재를 제공하는 것이다.The present invention is to solve such a problem, an object of the present invention is to provide a fluid sealing member provided to improve the wear resistance without a decrease in wear resistance as well as to improve the wear resistance without a decrease in fluid sealing performance. It is.

이러한 목적을 달성하기 위해 본 발명에 따른 유체 밀폐용 실링부재는 적어도 하나가 이동되어 상호 진퇴 운동하는 내측부재와 외측부재 사이에 유체의 이동을 방지하도록 마련되고, 서로 다른 탄성재질로 마련되며 상기 내측부재와 외측부재 중 적어도 하나와 마찰하도록 마련된 마찰부와 상기 내측부재 및 외측부재와 마찰하지 않도록 마련된 비마찰부를 포함하며, 상기 마찰부의 재질이 상기 비마찰부보다 큰 탄성계수와 경도를 갖도록 마련된 것을 특징으로 한다.In order to achieve this object, the sealing member for fluid sealing according to the present invention is provided to prevent the movement of the fluid between the inner member and the outer member which at least one is moved to move forward and backward, is provided with different elastic materials and the inner And a friction part provided to friction with at least one of the member and the outer member, and a non-friction part provided so as not to rub with the inner member and the outer member, wherein the material of the friction part is provided to have a greater elastic modulus and hardness than the non-friction part. It features.

그리고 상기 마찰부는 상기 비마찰부를 감싸도록 마련된 것을 특징으로 한 다. And the friction portion is characterized in that it is provided to surround the non-friction.

또한, 상기 마찰부와 비마찰부는 상호 적층된 것을 특징으로 한다.In addition, the friction portion and the non-friction portion is characterized in that stacked on each other.

또한, 상기 실링부재는 링형상으로 마련되고, 상기 내측부재의 외면과 상기 외측부재의 내면 중 어느 하나에는 상기 실링부재를 수용하도록 수용홈이 마련된 것을 특징으로 한다. In addition, the sealing member is provided in a ring shape, characterized in that any one of the outer surface of the inner member and the inner surface of the outer member is provided with a receiving groove to accommodate the sealing member.

또한, 상기 내측부재는 유압브레이크 시스템에 채용되는 피스톤부재를 포함하는 것을 특징으로 하는 유체 밀폐용 실링부재.In addition, the inner member is a fluid sealing member, characterized in that it comprises a piston member which is employed in the hydraulic brake system.

다음에는 본 발명에 따른 유체 밀폐용 실링부재의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Next, a preferred embodiment of a fluid sealing member according to the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 유체 밀폐용 실링부재는 유압브레이크 시스템 등에 채용되는 피스톤부재와 실린더부재처럼 상호 진퇴운동하는 2개의 부재 사이에 설치되는 것으로, 상호 진퇴운동하는 2개의 부재 사이로 유체가 이동하는 것을 방지한다.The sealing member for fluid sealing according to the present invention is installed between two members that move forward and backward, such as a cylinder member and a piston member, which is employed in a hydraulic brake system, and prevents fluid from moving between two members moving forward and backward. .

도 2에 도시된 바와 같이, 이때 상기 실린더부재는 외측에 마련되는 외측부재(20)를 형성하게 되고, 상기 피스톤부재는 외측부재(20) 내부에서 진퇴운동하며 유체를 압축하는 내측부재(10)를 형성하며, 유체 밀폐용 실링부재(30)는 피스톤부재의 진퇴동작시 피스톤부재과 실린더부재 사이로 오일이 이동하는 것을 방지하도록 내측부재(10)와 외측부재(20) 사이에 설치된다.As shown in FIG. 2, at this time, the cylinder member forms an outer member 20 provided on the outer side, and the piston member moves in and out of the outer member 20 to compress the fluid. And a fluid sealing sealing member 30 is installed between the inner member 10 and the outer member 20 to prevent oil from moving between the piston member and the cylinder member when the piston member moves forward and backward.

실링부재(30)는 탄성변형이 가능하도록 탄성재질의 링형상으로 마련되고, 내측부재(10)의 외면에는 실링부재(30)가 수용되도록 수용홈(11)이 마련된다. 따라서 상기 실링부재(30)는 이러한 수용홈(11)에 수용된 상태에서 내측부재(10)와 함께 진선왕복 운동하게 된다. 물론 상기 수용홈(11)은 외측부재(20)의 내면에 형성될 수도 있으며 이때에도 실링부재(30)를 통한 유체의 밀폐기능은 동일하게 수행된다.The sealing member 30 is provided in a ring shape made of an elastic material to enable elastic deformation, and the receiving groove 11 is provided on the outer surface of the inner member 10 to accommodate the sealing member 30. Therefore, the sealing member 30 moves forward and backward along with the inner member 10 in the state accommodated in the receiving groove (11). Of course, the receiving groove 11 may be formed on the inner surface of the outer member 20 and at this time, the sealing function of the fluid through the sealing member 30 is performed in the same way.

한편, 본 발명에 따른 유체 밀폐용 실링부재(30)는 내측부재(10)와 외측부재(20)의 상호 진퇴동작시 외측부재(20)와 마찰하지 않도록 안쪽에 마련되는 비마찰부(31)와, 비마찰부(31)를 감싸도록 마련되며 외측부재(20)와 마찰하도록 마련되는 마찰부(32)를 포함하여 구성되며, 상기 마찰부(32)는 비마찰부(31)보다 큰 탄성계수와 경도를 갖는 탄성재질로 마련된다.On the other hand, the fluid sealing member 30 according to the present invention is a non-friction portion 31 is provided on the inside so as not to friction with the outer member 20 during mutual movement of the inner member 10 and the outer member 20. And a friction part 32 provided to surround the non-friction part 31 and provided to friction with the outer member 20, wherein the friction part 32 is larger in elasticity than the non-friction part 31. It is made of elastic material with modulus and hardness.

이와 같이 서로 다른 탄성재질의 마찰부(32)와 비마찰부(31)를 포함하는 유체 밀폐용 실링부재(30)의 구성은 실링부재(30)의 유체 밀폐 성능의 저하 없이 실링부재(30)의 내마모성이 향상되도록 하거나 실링부재(30)의 내마모성의 저하 없이 실링부재(30)의 유체 밀폐 성능을 향상시키기 위한 것이다.As such, the configuration of the fluid sealing member 30 including the friction part 32 and the non-friction part 31 of different elastic materials may be applied to the sealing member 30 without degrading the fluid sealing performance of the sealing member 30. To improve the wear resistance of the sealing member 30 or to improve the fluid sealing performance of the sealing member 30 without deterioration of the wear resistance of the sealing member (30).

보다 상세히 설명하자면, 실링부재(30)는 내측부재(10)의 외면과 외측부재(20)의 내면 사이에 어느 정도 가압된 상태로 설치되어 그 탄성복원력을 통해 유체를 밀폐시키도록 마련되므로, 이 실링부재(30)의 유체 밀폐 성능은 실링부재(30)가 외측부재(20)를 수직방향으로 미는 힘에 비례하게 되고, 이러한 힘은 실링부재(30)를 형성하는 재질의 탄성계수에 의해 크게 좌우된다. 또 내측부재(10)의 진퇴동작시 외측부재(20) 측 실링부재(30)에는 내측부재(10)의 진퇴방향과 반대방향으로 마찰력이 작용하게 되며, 이러한 마찰력은 실링부재(30)가 외측부재(20)를 수직방향으로 미는 힘에 비례하므로 실링부재(30)의 탄성계수가 커질수록 커지게 된다. In more detail, since the sealing member 30 is installed in a pressurized state to some extent between the outer surface of the inner member 10 and the inner surface of the outer member 20, the sealing member 30 is provided to seal the fluid through its elastic restoring force. The fluid sealing performance of the sealing member 30 is proportional to the force of the sealing member 30 pushing the outer member 20 in the vertical direction, and this force is largely influenced by the elastic modulus of the material forming the sealing member 30. Depends. In addition, the frictional force acts on the outer member 20 side sealing member 30 in the opposite direction to the advancing direction of the inner member 10 during the advancing and retracting operation of the inner member 10, the frictional force is the outer side of the sealing member 30 Since it is proportional to the pushing force of the member 20 in the vertical direction, the greater the elastic modulus of the sealing member 30 becomes larger.                     

따라서 상술한 바와 같이, 실링부재(30)의 마찰부(32)를 비마찰부(31)보다 큰 경도와 탄성계수를 갖도록 마련하고, 마찰부(32)와 비마찰부(31)의 탄성계수의 평균이 종래 하나의 재질로 마련되던 실링부재의 탄성계수와 같아지도록 마련할 경우, 본 발명에 따른 실링부재(30)는 외측부재(20)를 수직방향으로 미는 힘이 종래와 같게 되어 종래 실링부재와 같은 정도 수준의 유체밀폐성능을 유지하면서도 외측부재(20)와 마찰하게 되는 마찰부(32)의 경도가 증가함에 따라 유체밀폐성능의 저하 없이 내마모성이 향상될 수 있게 된다. Therefore, as described above, the friction portion 32 of the sealing member 30 is provided to have a hardness and elastic modulus larger than that of the non-friction portion 31, and the elastic coefficients of the friction portion 32 and the non-friction portion 31 are provided. When the average is provided to be equal to the elastic modulus of the sealing member that is conventionally provided with a single material, the sealing member 30 according to the present invention is the conventional pushing force to push the outer member 20 in the vertical direction as conventional As the hardness of the friction part 32 which rubs against the outer member 20 increases while maintaining the fluid sealing performance of the same level as the member, wear resistance can be improved without deterioration of the fluid sealing performance.

또한, 본 발명에 따른 실링부재(30)의 유체밀폐성능을 향상시키고자 할 경우에는 마찰부(32)와 비마찰부(31)의 탄성계수의 평균이 종래 하나의 재질로 마련되던 실링부재의 탄성계수보다 커지도록 한다. 그러면 마찰부(32)의 경도와 함께 실링부재(30)의 탄성계수가 증가되어 실링부재(30)의 내마모성이 종래 실링부재 정도의 수준을 유지할 수 있게 되면서도 탄성계수가 증가된 본 발명에 따른 실링부재(30)는 더 큰 힘으로 외측부재(20)를 수직방향을 밀 수 있게 되고, 이에 따라 내마모성의 저하 없이 실링부재(30)의 유체밀폐성능이 향상될 수 있게 된다.In addition, in order to improve the fluid sealing performance of the sealing member 30 according to the present invention, the average of the elastic modulus of the friction part 32 and the non-friction part 31 is a conventional material of the sealing member. Make it larger than the elastic modulus. Then the elastic modulus of the sealing member 30 increases with the hardness of the friction part 32 so that the wear resistance of the sealing member 30 can maintain the level of the conventional sealing member while the elastic modulus increases according to the present invention. The member 30 can push the outer member 20 in a vertical direction with a greater force, and thus the fluid sealing performance of the sealing member 30 can be improved without deteriorating wear resistance.

또한, 다른 실시예를 도시한 도 3과 같이, 본 발명에 따른 유체 밀폐용 실링부재(30')는 마찰부(32')와 비마찰부(31')가 상호 적층되도록 마련될 수도 있으며, 이때에도 외측부재(20)와 마찰하게 되는 마찰부(32')의 탄성계수와 경도를 비마찰부(31')보다 큰 재질로 형성하게 되면, 상기와 동일한 작용효과를 발휘할 수 있게 된다. 단 이때 상기 수용홈(11)이 외측부재(20)의 내면에 형성될 경우에는 마찰부(32')와 비마찰부(31')의 위치가 서로 바뀌도록 마련되어야 한다. In addition, as shown in FIG. 3 showing another embodiment, the fluid sealing member 30 'according to the present invention may be provided such that the friction part 32' and the non-friction part 31 'are laminated to each other. In this case, if the elastic modulus and hardness of the friction part 32 'to be rubbed with the outer member 20 are formed of a material larger than the non-friction part 31', the same effect as described above can be obtained. In this case, however, when the receiving groove 11 is formed on the inner surface of the outer member 20, the positions of the friction part 32 'and the non-friction part 31' must be provided to be interchanged.                     

그리고 상기 내측부재(10)와 외측부재(20)는 본 실시예들와 같이 두개 중 어느 하나 만이 직선왕복운동할 수도 있고, 본 실시예들과 달리 두개가 함께 직선왕복운동하며 상호 진퇴운동하도록 마련될 수도 있으며, 본 발명에 따른 유체 밀폐용 실링부재(30,30')는 유압브레이크 시스템 이외에도 상호 진퇴운동하는 2개의 부재 사이에 유체의 밀폐를 목적으로 사용되는 범위 내에서 어디에라도 적용될 수 있다.And the inner member 10 and the outer member 20 may be any one of two linear reciprocating movement as in the present embodiment, unlike the present embodiment, the two reciprocating linear movement together with the two to be provided In addition, the fluid sealing member 30, 30 'according to the present invention can be applied anywhere within the range used for the purpose of sealing the fluid between the two members to move forward and backward in addition to the hydraulic brake system.
