본 실시예의 이륜차용 서스펜션(10)은 자전거나 오토바이 등과 같은 이륜차(100)에 사용될 수 있다. 본 실시예의 이륜차용 서스펜션(10)은 유체저장부(12)에 저장된 유체가 압축시 유로(16)를 따라 공기저장부(15)로 이동하면서, 공기를 압축한다. 이때, 유로(16)에 설치된 밸브(18)를 이용하여 유체의 흐름을 제어함으로써, 이륜차용 서스펜션(10)의 강도(완충력)를 조절할 수 있다. 유체는 오일(oil)일 수 있다.The motorcycle suspension 10 of the present embodiment may be used in a motorcycle 100 such as a bicycle or a motorcycle. The motorcycle suspension 10 of the present embodiment compresses air while moving the fluid stored in the fluid storage unit 12 to the air storage unit 15 along the flow path 16 when the fluid is compressed. At this time, by controlling the flow of the fluid using the valve 18 provided in the flow path 16, it is possible to adjust the strength (buffer force) of the suspension for a two-wheeled vehicle. The fluid may be oil.

이륜차용 서스펜션(10)의 충격완충과 복원이 빠르면, 흔히 말해 말랑말랑하다라는 표현을 한다. 반면, 충격완충과 복원이 늦으면 딱딱하다라는 표현을 한다. 사람에 따라서, 서스펜션 강도에 대한 선호도가 다르다. 본 발명은 사용자의 선호도에 맞는 서스펜션 강도를 외부에서 조절할 수 있는 것이 기술적 특징이다.
If the shock absorbing and restoring of the two-wheel suspension (10) is fast, it is often expressed as fluttering. On the other hand, when shock shock and restoration are late, it is hard. Different people have different preferences for suspension strength. The present invention is a technical feature that can be adjusted from the outside the suspension strength according to the user's preference.

유압실린더(11)는 하부가 닫혀있으며, 상부가 개방된 형태로서, 관의 형태이다.
The hydraulic cylinder 11 is closed in the lower part, the upper part is open, and is in the form of a tube.

유압실린더(11)의 내부에는 유체저장부(12)가 가이드 결합한다. 유체 저장부(12)의 내부에는 오일과 같은 유체가 저장되어 있다. 유체저장부(12)의 하부는 개방되어 있으며, 개방된 부분은 패킹부재(131)가 결합된 고정 피스톤(13)으로 닫혀져 있다. 따라서, 유체가 외부로 흘러나오지 않는다. The fluid storage part 12 is guided to the inside of the hydraulic cylinder (11). The fluid such as oil is stored in the fluid reservoir 12. The lower portion of the fluid reservoir 12 is open, and the open portion is closed by the fixed piston 13 to which the packing member 131 is coupled. Therefore, the fluid does not flow out.

고정 피스톤(13)은 유압실린더(11)의 바닥면에 고정되어 있으며, 유체저장부(12)의 내벽과 가이드 결합된다. 도 3과 같이, 유체저장부(12)가 유압실린더(11)를 따라 가이드되며 하강할 경우, 고정된 고정 피스톤(13)에 의해서 유체저장부(12)의 체적은 작아지고, 유체는 압력을 받게 된다. The fixed piston 13 is fixed to the bottom surface of the hydraulic cylinder 11, the guide is coupled to the inner wall of the fluid reservoir 12. As shown in FIG. 3, when the fluid storage part 12 is guided along the hydraulic cylinder 11 and descends, the volume of the fluid storage part 12 is reduced by the fixed fixed piston 13, and the fluid reduces the pressure. Will receive.

종래에는 수축된 고정 피스톤(13)의 패킹부재(131)에 작은 홀을 뚫어 압력을 받은 유체가 하부로 이동되도록 함으로써, 충격을 완충하는 역할을 하였고, 복원은 별도의 스프링을 이용하였다. 그러나, 본 실시예의 이륜차용 서스펜션(10)에서는 유체저장부(12)에서 압력을 받은 유체를 유로(16)를 통하여 공기 저장부(15)로 이동시킨다.
Conventionally, a small hole is made in the packing member 131 of the contracted fixed piston 13 to move the pressured fluid downward, thereby cushioning the impact, and restoring a separate spring. However, in the suspension for a two-wheeled vehicle according to the present embodiment, the fluid pressurized by the fluid storage unit 12 is moved to the air storage unit 15 through the flow path 16.

유압실린더(11)와 대응되는 형상으로, 공기압실린더(14)가 평행하게 배치된다. 공기압실린더(14)는 하부가 닫혀있으며, 상부는 개방되어 있다. In a shape corresponding to the hydraulic cylinder 11, the pneumatic cylinder 14 is arranged in parallel. The pneumatic cylinder 14 is closed at the bottom and open at the top.

공기저장부(15)는 내부에 공기를 저장하며, 상하부가 닫혀진 형상이다. 공기저장부(15)는 공기압실린더(14)의 내부와 가이드 결합한다.
The air storage unit 15 stores air therein, and the upper and lower parts are closed. The air storage unit 15 is guided to the inside of the pneumatic cylinder (14).

유로(16)는 유체저장부(12)와 연결되며, 유체저장부(12)의 유체가 이동할 수 있는 통로가 된다. 유로(16)는 공기저장부(15)의 상부를 관통하여 바닥방향으로 연장되어 결합된다.
The flow path 16 is connected to the fluid storage unit 12 and becomes a passage through which the fluid in the fluid storage unit 12 can move. The flow path 16 extends in the bottom direction through the upper portion of the air storage unit 15 and is coupled thereto.

유동 피스톤(17)은 유로(16)의 외벽과 공기저장부(15)의 내벽 사이에 개재되어, 공기저장부(15)를 두 영역으로 구획한다. 유동 피스톤(17)은 유로(16)에 의해서 가이드되어, 공기저장부(15)의 상하방향으로 이동할 수 있다. 공기저장부(15)는 캡(151)으로 닫혀있다.
The flow piston 17 is interposed between the outer wall of the flow path 16 and the inner wall of the air reservoir 15 to divide the air reservoir 15 into two regions. Flow piston 17 is guided by the flow path 16, it can move in the vertical direction of the air storage unit (15). The air storage unit 15 is closed by the cap 151.

유로(16)에는 밸브(18)가 결합된다. 밸브(18)는 유로(16)의 내부를 넓히거나 좁혀, 유로(16) 내부로 흐르는 유체의 이동양을 조절할 수 있다. 유로(16)는 외부로 노출되어 있어서, 사용자가 쉽게 조절할 수 있다.
The valve 18 is coupled to the flow path 16. The valve 18 may widen or narrow the inside of the flow path 16 to adjust the amount of movement of the fluid flowing into the flow path 16. The flow path 16 is exposed to the outside, so that the user can easily adjust it.

본 실시에의 이륜차용 서스펜션(10)에 힘이 가해지지 않을 경우, 도 2와 같이, 유압실린더(11)로부터 유체저장부(12)가 외부로 돌출되어 있다. 이후, 충격이 주어져서 유체저장부(12)에 힘이 실릴 경우, 유체저장부(12)는 유압실린더(11)의 내벽에 가이드 되면서 하강한다. 이때, 고정 피스톤(13)에 의해서, 유체저장부(12)의 유체는 압력을 받게 되고, 유체는 유로(16)를 통하여 공기저장부(15)의 하부로 이동한다. When no force is applied to the motorcycle suspension 10 of the present embodiment, the fluid storage portion 12 protrudes outward from the hydraulic cylinder 11 as shown in FIG. 2. Then, when a force is applied to the fluid storage unit 12 by the impact, the fluid storage unit 12 is lowered while being guided to the inner wall of the hydraulic cylinder (11). At this time, by the fixed piston 13, the fluid of the fluid reservoir 12 is pressured, the fluid is moved to the lower portion of the air reservoir 15 through the flow path (16).

공기저장부(15)의 하부와 상부는 유동 피스톤(17)에 의해서 구획되어 있다. 유압에 의해서 유동 피스톤(17)은 상부로 이동하며, 공기저장부(15)의 상부에 위치하는 공기를 압축한다. 도 1과 같이, 공기저장부(15)와 유체저장부(12)는 브릿지(bridge)에 의해서 연결되어 있으므로, 함께 하강하고, 함께 상승한다.The lower part and the upper part of the air storage unit 15 are partitioned off by the flow piston 17. The hydraulic piston 17 moves upward by the hydraulic pressure, and compresses the air located above the air storage unit 15. As shown in FIG. 1, since the air storage unit 15 and the fluid storage unit 12 are connected by a bridge, the air storage unit 15 and the fluid storage unit 12 are lowered together and ascended together.

외부로 노출된 밸브(18)를 조절하여, 유로(16)를 좁힐 경우 유체의 흐름이 원활하지 않아 외부에서 강한 힘이 주어지더라도공기저장부(15)와 유체저장부(12)가 하강하는 속도가 느려진다. 반면, 유로(16)를 확장할 경우 유체저장부(12)의 유체가 공기저장부(15)로 이동하여 공기저장부(15)와 유체저장부(12)는 하강하는 속도가 빨라진다.When the flow channel 16 is narrowed by adjusting the valve 18 exposed to the outside, the air storage unit 15 and the fluid storage unit 12 are lowered even when a strong force is applied because the fluid flow is not smooth. Slow down On the other hand, when the flow path 16 is expanded, the fluid in the fluid storage unit 12 moves to the air storage unit 15, and the air storage unit 15 and the fluid storage unit 12 are lowered in speed.

한편, 외부 힘이 사라지면, 공기저장부(15)압축된 공기가 다시 팽창하여 도 2와 같이, 공기저장부(15)와 유체저장부(12)를 밀어올린다.
On the other hand, when the external force disappears, the air compressed by the air storage unit 15 expands again to push up the air storage unit 15 and the fluid storage unit 12, as shown in FIG.

결과적으로, 유로(16)에 결합된 밸브(18)를 조절함으로써, 이륜차용 서스펜션(10)의 강도를 조절할 수 있다. 아울러, 공기의 복원력에 의해서 다시 공기저장부(15)와 유체저장부(12)가 원위치된다.
As a result, by adjusting the valve 18 coupled to the flow path 16, the strength of the suspension for motorcycles 10 can be adjusted. In addition, the air storage unit 15 and the fluid storage unit 12 are returned to their original positions by the restoring force of the air.
