Description

이륜차용 유압 브레이크 장치{Hydraulic brake system for motorcycle}Hydraulic brake system for motorcycle

본 발명은 이륜차의 브레이크 장치에 관한 것으로서, 더욱 상세하게는 이륜차의 전륜 디스크에 설치하여 급제동 발생시 전륜을 중심으로 하여 관성에 의해 차체와 함께 후륜이 들리는 현상을 방지하여 안전 사고를 미연에 방지할 수 있도록 하는 이륜차용 유압 브레이크 장치에 관한 것이다.The present invention relates to a brake device for a two-wheeled vehicle, and more particularly, it can be installed on a front wheel disk of a two-wheeled vehicle to prevent a phenomenon in which the rear wheels are lifted together with the vehicle body due to inertia around the front wheels when sudden braking occurs, thereby preventing a safety accident in advance. It relates to a hydraulic brake system for a two-wheeled vehicle.

통상 이륜차는, 본체를 이루는 차체의 전방부와 후방부에 각각 바퀴가 한 개씩 장착되어 구를 수 있도록 되어 있고, 엔진, 전기 모터 등과 같은 동력원을 통해 주행하는 것으로 자전거나 오토바이가 해당될 수 있다.In general, a two-wheeled vehicle has one wheel mounted on each of the front and rear portions of the body constituting the main body so that it can be rolled, and is driven by a power source such as an engine or an electric motor, and may be a bicycle or a motorcycle.

상기한 이륜차는 조향을 위해 핸들이 구비되고, 제동을 위한 브레이크 장치가 구비되어 핸들을 통해 주행방향을 설정하고 브레이크 장치를 통해 주행을 제어하게 된다. The above-described two-wheeled vehicle is provided with a steering wheel for steering and a brake device for braking to set a traveling direction through the handle and control the traveling through the brake device.

상기 브레이크 장치는, 이륜차의 경우에 있어 전륜과 후륜에 각각 제동 수단이 구비되도록 하여 전륜과 후륜을 서로 독립적으로 제동시키도록 하고있다. In the case of a two-wheeled vehicle, the brake device brakes the front and rear wheels independently of each other by providing braking means respectively to the front and rear wheels.

예를 들어, 이륜차는 핸들의 좌우 위치에 각각 브레이크 레버가 구비되고, 전륜 브레이크와 후륜 브레이크는 각각의 브레이크 레버에 의해 독립적으로 작동된다. 그런데, 이륜차는 무게 중심이 높기 때문에 후륜의 제동 없이 전륜만이 제동되거나, 후륜의 제동이 이루어지더라도 전륜의 제동보다 후륜의 제동이 늦게 이루어지는 경우 관성에 의해 이륜차가 전복될 위험이 높다. For example, in a two-wheeled vehicle, brake levers are provided at left and right positions of a steering wheel, respectively, and a front brake and a rear brake are independently operated by the respective brake levers. However, since the two-wheeled vehicle has a high center of gravity, there is a high risk of the two-wheeled vehicle overturning due to inertia when only the front wheels are braked without braking of the rear wheels, or when the rear wheels are braked later than the front wheels even when the rear wheels are braked.

즉, 주행 중 전륜측에 제동력이 발생되면 관성에 의해 전륜의 지면 지지점을 기준으로 하여 후륜 바퀴가 운전자와 함께 전방을 향하여 상향으로 들리면서 회전되는 전복 사고가 발생되고 있다.That is, when a braking force is generated on the front wheel side while driving, an overturning accident occurs in which the rear wheel is rotated while being lifted upward along with the driver based on the ground support point of the front wheel due to inertia.

특히, 고속으로 주행하거나 내리막길을 주행할 때 브레이크를 잘못 조작할 경우 전복 위험이 더욱 높다. In particular, when driving at high speed or driving downhill, if the brake is operated incorrectly, the risk of overturning is higher.

이를 해결하기 위해서는 전륜과 후륜에 위치한 브레이크 시스템이 차체에 발생되는 관성력을 순차적으로 제어하면 되는데 이를 위한 장치로 유압식 브레이크 시스템이 제시된 바 있다.In order to solve this problem, the brake systems located on the front and rear wheels need to sequentially control the inertial force generated on the vehicle body. As a device for this, a hydraulic brake system has been proposed.

하지만, 상기한 유압식 브레이크 시스템은 전륜과 후륜을 순차적으로 제어해야 함에 따라 장비 설치에 따른 공간이 확보되어야 하고 또한 비용이 고가이어서 설치가 힘든 문제점이 있다.However, since the hydraulic brake system has to sequentially control the front wheels and the rear wheels, a space for equipment installation must be secured, and the installation is difficult because the cost is high.

또한, 상기 하우징(110)의 일측에 상기 오일저장공간(S)의 오일을 마스터실린터(10)의 오일탱크(14)로 이동되도록 하는 오일튜브(180)가 구비되며, 상기 오일튜브(180)에 오일이 일방향으로 안내되도록 체크밸브(190)가 더 설치된 것을 적용할 수 있다.In addition, an oil tube 180 is provided on one side of the housing 110 to move the oil in the oil storage space S to the oil tank 14 of the master cylinder 10, and the oil tube 180 ) can be applied that the check valve 190 is further installed so that the oil is guided in one direction.

이상에서와 같이 구성되는 본 발명에 따른 이륜차용 유압 브레이크 장치의 작동 상태를 설명하면 다음과 같다.An operating state of the hydraulic brake device for a two-wheeled vehicle according to the present invention configured as described above will be described as follows.

도 1에 도시된 바와 같이 이륜차를 통해 주행 중 전륜 브레이크를 동작시키게 되면, 레버(12)가 이동하게 되고, 순차적으로 마스터실린더(10)를 이루는 푸시로드(13)가 전진하여 리턴스프링(15)을 압축시키면서 오일탱크(14)의 오일을 캘리퍼(20)로 밀어내게 된다. 그러면 오일이 캘리퍼(20)와 연결된 튜브(25)를 통해 오일실(26)로 전달되고 오일실(26)의 오일이 양쪽 피스톤(22)을 동시에 밀게 되고 이때, 피스톤(22)의 패드(23)가 전륜 디스크(30)의 양면을 밀착하며 전륜 디스크(30)의 회전을 제어하게 된다.As shown in FIG. 1, when the front wheel brake is operated while driving through the two-wheeled vehicle, the lever 12 moves, and the push rod 13 constituting the master cylinder 10 sequentially advances to the return spring 15. While compressing the oil, the oil in the oil tank 14 is pushed out by the caliper 20 . Then, the oil is transferred to the oil chamber 26 through the tube 25 connected to the caliper 20, and the oil in the oil chamber 26 pushes both pistons 22 at the same time. At this time, the pads 23 of the piston 22 ) adheres to both sides of the front wheel disk 30 and controls the rotation of the front wheel disk 30 .

그러면, 전륜 디스크(30)는 지면에 대해 마찰 저항을 발생시키며 정지상태를 이루게 되는데, 관성력이 비교적 크게 발생되는 경우 차체가 전륜 디스크(30)의 지면 지지점을 중심으로 강한 마찰력을 발생하게 된다.Then, the front wheel disk 30 generates frictional resistance with respect to the ground and achieves a stationary state. When the inertial force is relatively large, the vehicle body generates a strong frictional force centered on the ground support point of the front wheel disk 30 .

이때, 도 2에 도시된 바와 같이 오일 압력이 오일압력 완충기(100)의 피스톤(130)을 밀게 되고, 피스톤(130)은 상향으로 리턴스프링(120)을 압축하며 들어올려지게 되는데, 피스톤(130)의 하단이 링부재(140)을 통과하는 경우 링부재(140)와 링부재(140)사이에 공간이 노출되고 노출된 틈새를 통해 오일이 급격하게 이동하게 되어 순간적인 완충력이 발생되며 이를 통해 전륜 디스크(30)에 발생되는 관성력이 제어되게 된다.At this time, as shown in FIG. 2 , the oil pressure pushes the piston 130 of the oil pressure buffer 100 , and the piston 130 is lifted while compressing the return spring 120 upward. ), when the lower end passes through the ring member 140, the space between the ring member 140 and the ring member 140 is exposed, and the oil rapidly moves through the exposed gap, thereby generating an instantaneous buffering force. The inertia force generated in the front wheel disk 30 is controlled.
