Description

자전거용 무전원 안티록 브레이크용 브레이크 디스크 및 이를 이용한 자전거용 무전원 안티록 브레이크 시스템Brake discs for non-powered anti-lock brakes for bicycles and non-powered anti-lock brake systems for bicycles using the same
본 발명은 자전거용 무전원 안티록 브레이크용 브레이크 디스크 및 이를 이용한 자전거용 무전원 안티록 브레이크 시스템에 관한 것이다.The present invention relates to a brake disc for a non-powered anti-lock brake for a bicycle and a non-powered anti-lock brake system for a bicycle using the same.
안티록 브레이크(Anti-lock Brake) 또는 ABS(Anti-lock Brake System)는 차량을 제동할 때에 브레이크 및 타이어가 잠기는 것을 방지하는 브레이크 시스템을 말한다. 제동시에 브레이크 및 타이어가 잠기게 되면 제동 중의 조향이 곤란해짐으로써 운전자를 포함한 차량 탑승자가 위험하게 될 수 있다. 안티록 브레이크는 제동 중에도 브레이크 및 타이어가 잠기지 않도록 함으로써, 조향을 가능케 하여 운전자를 포함한 차량 탑승자가 제동 중에 나타나는 위험요소를 회피할 수 있도록 한다. An anti-lock brake or an anti-lock brake system (ABS) refers to a brake system that prevents a brake and tires from locking when braking a vehicle. If the brakes and tires are locked during braking, steering during braking may become difficult, which may endanger vehicle occupants including the driver. Anti-lock brakes prevent the brakes and tires from locking even during braking, enabling steering and allowing vehicle occupants, including the driver, to avoid hazards that appear during braking.
이륜차의 경우 제동 중에 전륜(front wheel)이 잠기면 조향이 곤란해질 뿐만 아니라 전륜의 미끄러짐(slip)이 발생함으로써 차량이 전도되는 위험이 매우 높아지게 된다. 이러한 이유로, 그동안 안티록 브레이크는 주로 사륜차에 적용되어 왔지만 이륜차에 대해서도 안티록 브레이크의 필요성은 여전히 크다. In the case of a two-wheeled vehicle, if the front wheels are locked during braking, not only steering becomes difficult, but also the risk of overturning of the vehicle becomes very high due to slippage of the front wheels. For this reason, while anti-lock brakes have been mainly applied to four-wheeled vehicles, the need for anti-lock brakes is still great for two-wheeled vehicles.
다수의 선행기술에서는 안티록 브레이크의 동작을 위하여 브레이크 패드를 1초 당 수십 회 이상 개폐시키는 전자적 장치를 개시하고 있다. 엔진, 발전기(generator) 및 배터리가 차량에 탑재되어 있는 오토바이의 경우에는 이처럼 운전 중 전력의 상시 공급을 필요로 하는 전자적 방식의 안티록 브레이크 시스템도 효과적으로 활용될 수 있다.A number of prior art discloses an electronic device that opens and closes a brake pad dozens of times per second or more for the operation of the anti-lock brake. In the case of a motorcycle in which an engine, a generator, and a battery are mounted on a vehicle, an electronic anti-lock brake system that requires constant power supply while driving can be effectively utilized.
그러나, 운전 중 상시 전원을 탑재하지 않는 경우가 일반적인 보통의 자전거에 대해서는 전자적 방식의 안티록 브레이크 시스템을 활용하는 것이 곤란하다. However, it is difficult to use the electronic anti-lock brake system for a normal bicycle that does not always have power installed while driving.
또한, 지금까지 알려진 안티록 브레이크 시스템은 대부분 크고 무겁고 복잡한 기계적 구조 및 복잡한 전자회로로 이루어지므로, 주로 사람의 힘으로 운행되는 자전거에 탑재되어 운용되기에는 곤란하였다. In addition, since most of the known anti-lock brake systems are large, heavy, and have a complex mechanical structure and a complex electronic circuit, it is difficult to be mounted and operated in a bicycle driven mainly by human power.
따라서, 상시 전원을 필요로 하지 않는 간단한 구조의 경량 안티록 브레이크가 필요하게 된다.Accordingly, there is a need for a lightweight anti-lock brake having a simple structure that does not require a constant power supply.
본 발명은 상기와 같은 문제를 해결하기 위하여 착안된 것으로서, 상시 전원을 필요로 하지 않는 간단한 구조의 경량 안티록 브레이크를 구현할 수 있는 자전거용 무전원 안티록 브레이크용 브레이크 디스크 및 이를 이용한 자전거용 무전원 안티록 브레이크 시스템을 제공하는 것을 목적으로 한다. The present invention was conceived to solve the above problems, and a brake disc for a non-powered anti-lock brake for a bicycle that can implement a lightweight anti-lock brake of a simple structure that does not require a constant power source and a non-powered anti-lock for a bicycle using the same An object of the present invention is to provide a brake system.

In order to achieve the above object, a brake disc for a non-powered anti-lock brake for a bicycle according to an example includes a rotor, a disc arm and a hub fastening part, wherein the rotor has a thin first rotor unit and a thick and a second rotor unit, and a plurality of third rotor units whose thickness is gradually changed while connecting the first rotor unit and the second rotor unit.

이하 도면을 참조하여 자전거용 무전원 안티록 브레이크에 대하여 자세히 설명하기로 한다. Hereinafter, a non-powered anti-lock brake for a bicycle will be described in detail with reference to the drawings.
도 1은 자전거용 무전원 안티록 브레이크용 브레이크 디스크의 일례를 나타낸 도면이다.1 is a view showing an example of a brake disc for a non-powered anti-lock brake for a bicycle.
도 1에서 나타낸 바와 같이, 자전거용 무전원 안티록 브레이크용 브레이크 디스크(10)는 로터(12), 디스크 암(14) 및 허브 체결부(140)를 포함하여 이루어진다. As shown in FIG. 1 , the brake disk 10 for a non-powered anti-lock brake for a bicycle includes a rotor 12 , a disk arm 14 , and a hub fastening unit 140 .
로터(12)는 후술하는 브레이크 캘리퍼에 구비된 브레이크 패드가 밀착됨으로써 제동이 이루어지는 금속 재질의 판이다. The rotor 12 is a metal plate on which braking is performed by closely contacting a brake pad provided on a brake caliper to be described later.
허브 체결부(140)는 자전거용 무전원 안티록 브레이크용 브레이크 디스크(10)가 후술하는 휠의 허브에 장착될 수 있도록 하는 연결부이다. The hub fastening part 140 is a connection part that allows the brake disc 10 for a non-powered anti-lock brake for a bicycle to be mounted on a hub of a wheel, which will be described later.
자전거용 브레이크 디스크는 일반적으로 경량화를 위하여 로터(12)와 허브 체결부(140)를 제외한 나머지 부분을 삭제하는 경향이 있다. 그 결과, 삭제되지 않은 부분으로서 로터(12)를 허브 체결부(140)와 연결시켜주게 되는 디스크 암(14)이 형성된다. In general, a brake disc for a bicycle tends to remove the remaining parts except for the rotor 12 and the hub fastening part 140 in order to reduce the weight. As a result, the disk arm 14 that connects the rotor 12 with the hub fastening part 140 is formed as a non-deleted part.
도 1의 자전거용 무전원 안티록 브레이크용 브레이크 디스크(10)의 가장 큰 특징은, 일반적인 브레이크 디스크의 로터와 달리, 로터(12) 면이 평탄하지 않다는 점이다. 평탄하지 않은 로터(12) 면에 의하여 안티록 브레이크의 성능이 발휘된다. The biggest characteristic of the brake disk 10 for the non-powered anti-lock brake for a bicycle of FIG. 1 is that, unlike the rotor of a general brake disk, the surface of the rotor 12 is not flat. Anti-lock brake performance is exhibited by the uneven surface of the rotor 12 .
도 2는 도 1의 자전거용 무전원 안티록 브레이크용 브레이크 디스크의 구조를 더욱 상세히 나타낸 부분 확대도이다.FIG. 2 is a partially enlarged view showing the structure of a brake disc for a non-powered anti-lock brake for a bicycle of FIG. 1 in more detail.
도 2에서 나타낸 바와 같이, 도 2의 로터(12)는 그 구조에 따라 네 부분으로 분할할 수 있다. As shown in Fig. 2, the rotor 12 of Fig. 2 can be divided into four parts according to its structure.
제1로터유닛(12A)은 로터(12) 중에서 두께가 상대적으로 얇은 부분이다. The first rotor unit 12A is a relatively thin portion of the rotor 12 .
제2로터유닛(12C)은 로터(12) 중에서 두께가 상대적으로 두꺼운 부분이다. The second rotor unit 12C is a relatively thick portion of the rotor 12 .
제3로터유닛(12B,12D)은 제1로터유닛(12A)과 제2로터유닛(12C)을 연결하면서 점진적으로 두께가 변화하는 부분이다. The third rotor units 12B and 12D are portions whose thickness is gradually changed while connecting the first rotor unit 12A and the second rotor unit 12C.
제1로터유닛(12A), 제2로터유닛(12C) 및 제3로터유닛(12B,12D)은, 도 2에서 나타낸 것처럼 제1로터유닛(12A) - 제3로터유닛(12B) - 제2로터유닛(12C) - 제3로터유닛(12D)의 순서로 반복적으로 배치된다. The first rotor unit 12A, the second rotor unit 12C and the third rotor units 12B and 12D are, as shown in FIG. 2, the first rotor unit 12A - the third rotor unit 12B - the second The rotor unit 12C - the third rotor unit 12D are repeatedly arranged in the order.
각각의 제1로터유닛(12A)의 너비는 안티록 제동효과가 발휘될 수 있는 한도 내에서 자유롭게 설정할 수 있다. The width of each of the first rotor units 12A can be freely set within the limit in which the anti-lock braking effect can be exerted.
제1로터유닛(12A)의 너비가 넓어질수록 제동력이 변화하는 주기가 길어진다. 따라서 일정 너비 이상이 되면 일반적인 주행 속도에서는 사실상 브레이크 안티록 효과가 발생하지 않게 된다. As the width of the first rotor unit 12A increases, the period during which the braking force changes becomes longer. Therefore, when the width exceeds a certain width, the brake anti-lock effect does not actually occur at normal driving speed.
반면, 제1로터유닛(12A)의 너비가 좁아질수록 제동력이 변화하는 주기가 짧아진다. 만약 일정 너비 이하가 되면, 일반적인 주행 속도에서는 실질적으로 제1로터유닛(12A)과 제2로터유닛(12C)의 간격이 지나치게 짧아지게 되어 사실상 브레이크 안티록 효과가 발생하지 않게 된다. On the other hand, as the width of the first rotor unit 12A becomes narrower, the period of changing the braking force becomes shorter. If the width is less than a certain width, the distance between the first rotor unit 12A and the second rotor unit 12C is substantially shortened at a normal driving speed, so that the brake anti-lock effect does not actually occur.
각각의 제2로터유닛(12C)의 두께는 일반적인 디스크 로터의 두께로 형성하는 것이 좋다. 캘리퍼 및 브레이크 패드 등을 교체하지 않고도 안티록 브레이크 효과를 얻기 위한 것이 본 발명의 목표이므로, 일반적인 디스크 로터와 같은 두께로 형성하여야 디스크 브레이크의 캘리퍼와 브레이크 패드에 대해서 별도의 유격 변경 등 조작을 할 필요가 없어지기 때문이다. The thickness of each of the second rotor units 12C is preferably formed to the thickness of a general disk rotor. Since it is a goal of the present invention to obtain the anti-lock brake effect without replacing the caliper and brake pads, it is necessary to separately change the clearance between the caliper and the brake pad of the disc brake when it is formed to have the same thickness as a general disc rotor. because it disappears
각각의 제1로터유닛(12A)의 두께는 제2로터유닛(12C)보다 얇으면 되는데, 1mm 정도의 차이만으로도 일반적인 주행 속도에서 안티록 브레이크 효과를 얻을 수 있다. 또한, 제1로터유닛(12A)의 두께는 일반적인 주행 환경에서 로터가 파손되지 않는 한도 내에서는 얇게 형성할 수 있다.The thickness of each of the first rotor units 12A may be thinner than that of the second rotor unit 12C, and the anti-lock brake effect can be obtained at a normal driving speed with only a difference of about 1 mm. In addition, the thickness of the first rotor unit 12A may be formed thin within a limit that the rotor is not damaged in a general driving environment.
제3로터유닛(12B,12D)의 두께가 점진적으로 변화하지 않는 경우에는, 제동시에 브레이크 패드의 모서리가 파손되어 브레이크 패드의 수명이 급격히 단축되거나 안티록 브레이크의 성능이 저하될 우려가 발생한다. 따라서 제3로터유닛(12B,12D)은 두께가 점진적으로 변화하도록 표면이 매끄러운 곡면으로 형성될 필요가 있다. When the thickness of the third rotor units 12B and 12D does not change gradually, the edge of the brake pad is damaged during braking, so that the life of the brake pad is rapidly shortened or the performance of the anti-lock brake is deteriorated. Therefore, the third rotor unit (12B, 12D) needs to be formed in a smooth curved surface so that the thickness is gradually changed.
도 3은 자전거용 무전원 안티록 브레이크가 적용된 자전거용 무전원 안티록 브레이크 시스템이 자전거의 전륜에 적용된 실시예를 나타낸 도면이다. 3 is a view showing an embodiment in which a non-powered anti-lock brake system for a bicycle to which a non-powered anti-lock brake for a bicycle is applied is applied to a front wheel of a bicycle.
도 3에서 나타낸 바와 같이, 자전거용 무전원 안티록 브레이크 시스템(1)은, 자전거용 무전원 안티록 브레이크용 브레이크 디스크(10)와 브레이크 캘리퍼(20)를 포함하여 이루어진다. As shown in FIG. 3 , the non-powered anti-lock brake system 1 for a bicycle includes a brake disc 10 and a brake caliper 20 for an unpowered anti-lock brake for a bicycle.
자전거용 무전원 안티록 브레이크용 브레이크 디스크(10)는 차륜(50)과 함께 허브(40)에 고정되며, 허브(40)는 포크(30)와 결합하여 자전거의 하중을 지지하게 된다. The brake disc 10 for the non-powered anti-lock brake for a bicycle is fixed to the hub 40 together with the wheel 50 , and the hub 40 is coupled to the fork 30 to support the load of the bicycle.
브레이크 캘리퍼(20)는 포크(30)의 브레이크 캘리퍼 결합부(32)에 고정된다. The brake caliper 20 is fixed to the brake caliper coupling portion 32 of the fork 30 .
브레이크 캘리퍼(20)는 브레이크 케이블(22)을 통하여 브레이크 레버(도면에 나타내지 않음)와 연결되며, 제동이 되도록 브레이크 레버가 조작되는 경우, 브레이크 케이블(22)을 통하여 브레이크 캘리퍼(20) 내의 브레이크 패드(도면에 나타내지 않음)가 자전거용 무전원 안티록 브레이크용 브레이크 디스크(10)의 로터(12)에 밀착됨으로써 제동이 이루어지게 된다.The brake caliper 20 is connected to a brake lever (not shown in the drawing) through a brake cable 22 , and when the brake lever is operated for braking, the brake pad in the brake caliper 20 through the brake cable 22 . (not shown in the drawing) is in close contact with the rotor 12 of the brake disc 10 for a non-powered anti-lock brake for a bicycle, whereby braking is performed.
도 4는 자전거용 무전원 안티록 브레이크 시스템의 작동 구조를 예시한 도면이다. 4 is a diagram illustrating an operation structure of a non-powered anti-lock brake system for a bicycle.
도 4(a)는 제동 전의 상태를 나타내며, 도 4(b) 및 도 4(c)는 제동 중에 안티록 브레이크 효과가 발생하는 상태를 나타낸다. 4(a) shows a state before braking, and FIGS. 4(b) and 4(c) show a state in which an anti-lock brake effect occurs during braking.
도 4(a)에서 나타낸 바와 같이, 브레이크 캘리퍼(20)는 브레이크 패드 하우징(24), 브레이크 패드(26) 및 패드 가동 로드(28)를 더 포함한다. 자전거용 디스크 브레이크 장치에서는 로터의 양쪽 면에 각각 브레이크 패드(26)가 배치되므로, 도면에서 나타낸 바와 같이 브레이크 패드 하우징(24), 브레이크 패드(26) 및 패드 가동 로드(28)는 각 로터마다 한 쌍씩 배치된다. As shown in FIG. 4A , the brake caliper 20 further includes a brake pad housing 24 , a brake pad 26 and a pad movable rod 28 . In the bicycle disc brake device, since the brake pads 26 are respectively disposed on both sides of the rotor, as shown in the figure, the brake pad housing 24, the brake pad 26, and the pad movable rod 28 are one for each rotor. placed in pairs.
한편, 브레이크 패드(26)는 제동력을 갖도록 레진(resin), 메탈릭, 세라믹 또는 세미 메탈릭 등 다양한 재질로 이루어진다. 경우에 따라서는 브레이크 패드(26)와 브레이크 패드 하우징(24)이 동일한 재질로 일체화된 경우도 있다. Meanwhile, the brake pad 26 is made of various materials such as resin, metallic, ceramic, or semi-metallic to have braking force. In some cases, the brake pad 26 and the brake pad housing 24 may be integrated with the same material.
패드 가동 로드(28)는 브레이크 케이블(22)의 작동을 브레이크 패드 하우징(24) 및 브레이크 패드(26)에 전달하는 역할을 수행한다. The pad actuating rod 28 serves to transmit the operation of the brake cable 22 to the brake pad housing 24 and the brake pad 26 .
본 발명에 따른 자전거용 무전원 안티록 브레이크 시스템을 구현할 수 있는 범위 내에서는 공지된 다양한 형태의 브레이크 패드 및 브레이크 패드 하우징 및 브레이크 캘리퍼가 다양하게 적용될 수 있다. Within the scope of realizing the non-powered anti-lock brake system for a bicycle according to the present invention, various known types of brake pads, brake pad housings, and brake calipers may be variously applied.
도 4(a)에서는 브레이크 레버가 조여지지 않아 브레이크 패드(26)와 로터(12)가 서로 이격되어 있다. 따라서 제동은 이루어지지 않는다. In FIG. 4A , the brake lever is not tightened, so that the brake pad 26 and the rotor 12 are spaced apart from each other. Therefore, braking is not performed.
도 4(b)는 브레이크 레버가 조여짐에 따라 브레이크 패드(26)와 로터(12)가 밀착된 상태를 나타낸다. 4(b) shows a state in which the brake pad 26 and the rotor 12 are in close contact as the brake lever is tightened.
도면에서 나타난 회전방향대로 차륜(50) 및 허브(40)를 통하여 차륜(50)에 고정된 자전거용 무전원 안티록 브레이크용 브레이크 디스크(10)가 회전하는 경우, 일반적으로는 브레이크 패드(26)와 로터(12)가 밀착되더라도 자전거 탑승자 및 자전거의 중량과 그에 따른 관성으로 인하여 로터(12)가 회전방향으로 밀려가게 된다. When the brake disk 10 for a non-powered anti-lock brake for a bicycle fixed to the wheel 50 through the wheel 50 and the hub 40 rotates in the rotational direction shown in the drawing, in general, the brake pad 26 and Even if the rotor 12 is in close contact, the rotor 12 is pushed in the rotational direction due to the weight of the bicycle occupant and the bicycle and the resulting inertia.
만약 자전거 탑승자 및 자전거의 중량에 비하여 브레이크 패드(26)와 로터(12)의 밀착에 따른 제동력이 충분하지 않으면, 로터(12)가 회전방향으로 밀려가게 됨으로써, 자전거는 지면에서 차륜(50)이 굴러가는 상태로 제동이 된다.If the braking force due to the close contact between the brake pad 26 and the rotor 12 is not sufficient compared to the weight of the bicycle occupant and the bicycle, the rotor 12 is pushed in the rotational direction, so that the bicycle wheel 50 moves from the ground. It is braked while rolling.
반면 자전거 탑승자 및 자전거의 중량에 비하여 브레이크 패드(26)와 로터(12)의 밀착에 따른 제동력이 충분하게 되면, 로터(12)가 회전방향으로 밀려가지 않음으로써, 자전거는 브레이크 잠김 현상이 발생한다. 즉 차륜(50)이 구르지 않게 된다. On the other hand, if the braking force due to the close contact between the brake pad 26 and the rotor 12 is sufficient compared to the weight of the bicycle occupant and the bicycle, the rotor 12 is not pushed in the rotational direction, thereby causing the bicycle to brake. . That is, the wheel 50 does not roll.
도 4(c)는 자전거용 무전원 안티록 브레이크 시스템에서 안티록 브레이크 효과가 발생하는 상황을 나타낸다. 4( c ) shows a situation in which an anti-lock brake effect occurs in a non-powered anti-lock brake system for a bicycle.
도 4(c)에서 나타낸 바와 같이, 도 4(b)에서 로터(12)가 회전방향으로 밀려나면, 얇은 제1로터유닛(12A)에서 두꺼운 제2로터유닛(12C)으로 이어지는 부분의 제3로터유닛(12B)이 나타나게 된다. 앞서 언급한 바와 같이 브레이크 패드(26)는 제1로터유닛(12A)이 끝나는 지점에서 브레이크 패드(26)의 모서리가 제3로터유닛(12B)과 접촉한다. 이후 제2로터유닛(12C)을 만나게 되면서 직전의 제1로터유닛(12A)과 밀착되었을 때보다 더욱 밀착된다. As shown in FIG. 4(c), when the rotor 12 is pushed in the rotational direction in FIG. 4(b), the third part of the thin first rotor unit 12A to the thick second rotor unit 12C The rotor unit 12B appears. As mentioned above, the edge of the brake pad 26 comes into contact with the third rotor unit 12B at the point where the first rotor unit 12A ends. Thereafter, as it meets the second rotor unit 12C, it is in close contact with the first rotor unit 12A immediately before.
이처럼 브레이크 패드(26)의 모서리가 제3로터유닛(12B) 및 제2로터유닛(12C)을 연속하여 만나게 되는 과정에서 밀착에 따른 부하가 발생하여 브레이크 패드(26)의 모서리가 제1로터유닛(12A)과 밀착되었을 때보다 제동력이 증가하게 된다. As described above, in the process in which the edge of the brake pad 26 continuously meets the third rotor unit 12B and the second rotor unit 12C, a load due to close contact is generated so that the edge of the brake pad 26 becomes the first rotor unit. The braking force increases compared to when it is in close contact with (12A).
즉, 상대적으로 낮은 제동력과 상대적으로 높은 제동력이 교호적으로 발생함에 따라, 결과적으로 자전거용 무전원 안티록 브레이크용 브레이크 디스크(10) 및 허브(40)를 통하여 연결되어 있는 차륜(50)은 잠기지 않게 된다. That is, as a relatively low braking force and a relatively high braking force are alternately generated, as a result, the brake disk 10 for the non-powered anti-lock brake for a bicycle and the wheel 50 connected through the hub 40 are not locked. do.
도 5는 자전거용 무전원 안티록 브레이크용 브레이크 디스크의 다른 실시예를 나타낸 도면이다.5 is a view showing another embodiment of a brake disc for a non-powered anti-lock brake for a bicycle.
도 5에서 나타낸 실시예는, 도 2의 실시예와 비교할 때 제1로터유닛(12A) 및 제2로터유닛(12C)이 극단적으로 짧아지고, 제3로터유닛(12B,12D)만을 남긴 변형 실시예로 볼 수 있다. In the embodiment shown in FIG. 5, as compared with the embodiment of FIG. 2, the first rotor unit 12A and the second rotor unit 12C are extremely short, and only the third rotor units 12B and 12D are left. can be seen as an example.
도 5에서 나타낸 실시예에서도 도 4에서 설명한 안티록 브레이크의 효과 발생 원리는 동일하게 적용된다. In the embodiment shown in FIG. 5, the principle of generating the effect of the anti-lock brake described in FIG. 4 is equally applied.
도 6은 자전거용 무전원 안티록 브레이크용 림의 일례를 나타낸 도면이다. 6 is a view showing an example of a rim for a non-powered anti-lock brake for a bicycle.
앞서의 실시예에서는 자전거용 무전원 안티록 브레이크 효과를 얻기 위하여, 디스크 브레이크 타입의 자전거 브레이크에서 새로운 로터의 형상을 제안하였다. In the previous embodiment, in order to obtain an anti-lock brake effect without power for a bicycle, a new rotor shape was proposed in the disc brake type bicycle brake.
도 6의 실시예에서는 자전거용 무전원 안티록 브레이크 효과를 얻기 위하여, 림 브레이크(rim brake) 타입의 자전거 브레이크에서 새로운 림의 형상을 제안한다. In the embodiment of FIG. 6 , a new rim shape is proposed in a rim brake type bicycle brake in order to obtain an anti-lock brake effect without power for a bicycle.
도 6에서 나타낸 바와 같이, 자전거용 무전원 안티록 브레이크용 림(2)은 림 몸체(62)와, 몸체의 양측면에 형성되는 제동면(60)을 포함하여 이루어진다. As shown in FIG. 6 , the rim 2 for a non-powered anti-lock brake for a bicycle includes a rim body 62 and braking surfaces 60 formed on both sides of the body.
림 몸체(62)는 일반적인 림 브레이크 타입의 림과 다르지 않은 형상으로 이루어진 자전거용 림이다. 림 몸체(62)에는 타이어 및 스포크가 결합되고, 스포크는 다시 허브에 결합함으로써 자전거 및 운전자의 하중을 지탱할 수 있도록 한다. The rim body 62 is a rim for a bicycle having a shape not different from that of a general rim brake type rim. A tire and a spoke are coupled to the rim body 62 , and the spoke is coupled to the hub again to support the load of the bicycle and the driver.
제동면(60)은 일반적인 림 브레이크 타입 브레이크의 패드와 밀착하여 제동을 수행한다. 제동면(60)은 일정 간격으로 돌출된 부분과 함몰된 부분이 교차하면서 형성되어 있다. The braking surface 60 performs braking in close contact with the pad of a general rim brake type brake. The braking surface 60 is formed by intersecting the protruding part and the recessed part at regular intervals.
도 7은 도 6의 자전거용 무전원 안티록 브레이크용 림의 구조를 더욱 상세히 나타낸 부분 확대도이다. 7 is a partially enlarged view showing the structure of the rim for the non-powered anti-lock brake for the bicycle of FIG. 6 in more detail.
도 7은 도 6의 자전거용 무전원 안티록 브레이크용 림(2)을 A-A' 단면부터 B-B' 단면까지를 나타내었다. 7 shows the rim 2 for the non-powered anti-lock brake for the bicycle of FIG. 6 from the A-A' section to the B-B' section.
도 7에서 나타낸 바와 같이, 자전거용 무전원 안티록 브레이크용 림(2)에서 제동면(60)은 림 몸체(62)의 외측면에 형성된다. B-B' 단면에서는 제동면(60)과 림 몸체(62)가 구분되도록 표시하였다. 그러나, 제동면(60)과 림 몸체(62)가 일체형으로 형성될 수 있다. 또한, 도면에서는 제동면(60)과 림 몸체(62) 사이에 단차가 존재하는 것으로 표현되었으나, 이러한 단차 또한 생략될 수 있다. As shown in FIG. 7 , in the rim 2 for a non-powered anti-lock brake for a bicycle, the braking surface 60 is formed on the outer surface of the rim body 62 . In the B-B' section, the braking surface 60 and the rim body 62 are marked to be distinguished. However, the braking surface 60 and the rim body 62 may be integrally formed. In addition, although it is expressed that a step exists between the braking surface 60 and the rim body 62 in the drawings, this step may also be omitted.
즉, 림 몸체(62)와 제동면(60) 사이의 경계면(600)을 점선으로 나타내었지만, 이 경계면(600)은 림 몸체(62)와 제동면(60) 사이의 접합면이 될 수도 있지만, 림 몸체(62)와 제동면(60)이 일체형으로 형성되는 경우에는 경계면(600)은 존재하지 않을 수도 있다. That is, although the interface 600 between the rim body 62 and the braking surface 60 is indicated by a dotted line, this interface 600 may be a joint surface between the rim body 62 and the braking surface 60, but , when the rim body 62 and the braking surface 60 are integrally formed, the interface 600 may not exist.
도 8은 도 6의 자전거용 무전원 안티록 브레이크용 림의 구조를 더욱 상세히 나타낸 부분 확대도의 다른 도면이다. 8 is another view of a partially enlarged view showing the structure of the rim for the non-powered anti-lock brake for the bicycle of FIG. 6 in more detail.
도 8에서 나타낸 바와 같이, 제동면(60)은 그 구조에 따라 네 부분으로 분할할 수 있다. As shown in FIG. 8 , the braking surface 60 can be divided into four parts according to its structure.
제1림유닛(60A)은 제동면(60) 중에서 두께가 상대적으로 얇은 부분이다. The first rim unit 60A is a relatively thin portion of the braking surface 60 .
제2림유닛(60C)은 제동면(60) 중에서 두께가 상대적으로 두꺼운 부분이다. The second rim unit 60C is a relatively thick portion of the braking surface 60 .
제3림유닛(60B,60D)은 제1림유닛(60A)과 제2림유닛(60C)을 연결하면서 점진적으로 두께가 변화하는 부분이다. The third rim unit 60B, 60D is a part whose thickness is gradually changed while connecting the first rim unit 60A and the second rim unit 60C.
제1림유닛(60A), 제2림유닛(60C) 및 제3림유닛(60B,60D)은, 도 8에서 나타낸 것처럼 제1림유닛(60A) - 제3림유닛(60B) - 제2림유닛(60C) - 제3림유닛(60D)의 순서로 반복적으로 배치된다. The first rim unit 60A, the second rim unit 60C and the third rim units 60B and 60D are, as shown in FIG. 8, the first rim unit 60A - the third rim unit 60B - the second The rim unit 60C - is repeatedly arranged in the order of the third rim unit 60D.
각각의 제1림유닛(60A)의 너비는 안티록 제동효과가 발휘될 수 있는 한도 내에서 자유롭게 설정할 수 있다. The width of each of the first rim units 60A can be freely set within the limit in which the anti-lock braking effect can be exerted.
제1림유닛(60A)의 너비가 넓어질수록 제동력이 변화하는 주기가 길어진다. 따라서 일정 너비 이상이 되면 일반적인 주행 속도에서는 사실상 브레이크 안티록 효과가 발생하지 않게 된다. As the width of the first rim unit 60A increases, the period of changing the braking force becomes longer. Therefore, when the width exceeds a certain width, the brake anti-lock effect does not actually occur at normal driving speed.
반면, 제1림유닛(60A)의 너비가 좁아질수록 제동력이 변화하는 주기가 짧아진다. 만약 일정 너비 이하가 되면, 일반적인 주행 속도에서는 실질적으로 제1림유닛(60A)과 제2림유닛(60C)의 간격이 지나치게 짧아지게 되어 사실상 브레이크 안티록 효과가 발생하지 않게 된다. On the other hand, as the width of the first rim unit 60A becomes narrower, the period in which the braking force changes becomes shorter. If the width is less than a certain width, the distance between the first rim unit 60A and the second rim unit 60C is substantially shortened at a normal driving speed, so that the brake anti-lock effect does not actually occur.
각각의 제2림유닛(60C)의 두께는 일반적인 자전거 림의 폭을 갖도록 형성하는 것이 좋다. 브레이크암, 브레이크 패드 등을 교체하지 않고도 안티록 브레이크 효과를 얻기 위한 것이 본 발명의 목표이므로, 일반적인 자전거 림과 같은 폭으로 형성하여야 림 브레이크의 브레이크암, 브레이크 패드에 대해서 별도의 유격 변경 등 조작을 할 필요가 없어지기 때문이다. The thickness of each second rim unit 60C is preferably formed to have the width of a general bicycle rim. Since it is a goal of the present invention to obtain the anti-lock brake effect without replacing the brake arm and brake pad, it should be formed to have the same width as the rim of a general bicycle so that the brake arm and brake pad of the rim brake can be operated separately, such as changing the clearance. because there is no need to do it.
각각의 제1림유닛(60A)의 두께는 제2림유닛(60C)보다 얇으면 되는데, 1mm 정도의 차이만으로도 일반적인 주행 속도에서 안티록 브레이크 효과를 얻을 수 있다. 또한, 제1림유닛(60A)의 두께는 일반적인 주행 환경에서 로터가 파손되지 않는 한도 내에서는 얇게 형성할 수 있다.The thickness of each of the first rim units 60A may be thinner than that of the second rim units 60C, and only a difference of about 1 mm can provide an anti-lock brake effect at a normal driving speed. In addition, the thickness of the first rim unit 60A may be formed to be thin within the limit that the rotor is not damaged in a general driving environment.
제3림유닛(60B,60D)의 두께가 점진적으로 변화하지 않는 경우에는, 제동시에 브레이크 패드의 모서리가 파손되어 브레이크 패드의 수명이 급격히 단축되거나 안티록 브레이크의 성능이 저하될 우려가 발생한다. 따라서 제3림유닛(60B,60D)은 두께가 점진적으로 변화하도록 표면이 매끄러운 곡면으로 형성될 필요가 있다.When the thickness of the third rim units 60B and 60D does not change gradually, the edge of the brake pad is damaged during braking, so that the life of the brake pad is rapidly shortened or the performance of the anti-lock brake is deteriorated. Therefore, the third rim unit (60B, 60D) needs to be formed in a smooth curved surface so that the thickness is gradually changed.
도 9는 자전거용 무전원 안티록 브레이크용 림이 적용된 자전거용 무전원 안티록 브레이크의 제공 원리를 나타낸 도면이다.9 is a view showing a principle of providing a non-powered anti-lock brake for a bicycle to which a rim for a non-powered anti-lock brake for a bicycle is applied.
도 9에는 이른바 “V-브레이크”가 자전거용 무전원 안티록 브레이크용 림과 결합하여 자전거용 무전원 안티록 브레이크로 기능하는 경우를 나타내었다. 9 shows a case in which the so-called “V-brake” functions as a non-powered anti-lock brake for a bicycle in combination with a rim for a non-powered anti-lock brake for a bicycle.
브레이크암(80)에는 브레이크 샤프트(88)를 거쳐서 브레이크 카트리지(84)에 결합되어 있는 브레이크 패드(86)가 연결되어 있다. 운전자가 제동을 하기 위하여 레버를 움켜쥘 때, 블록 화살표 방향으로 브레이크암(80) 및 브레이크 패드(86)가 이동하게 된다. 이에 따라, 브레이크 패드(86)는 제동면(60)과 밀착된다. A brake pad 86 coupled to the brake cartridge 84 is connected to the brake arm 80 via a brake shaft 88 . When the driver grabs the lever to apply the brake, the brake arm 80 and the brake pad 86 move in the direction of the block arrow. Accordingly, the brake pad 86 is in close contact with the braking surface 60 .
브레이크 패드(86)가 제동면(60)과 밀착되었을 때, 제동면(60)의 두께가 변화함으로써 상대적으로 낮은 제동력과 상대적으로 높은 제동력이 교호적으로 발생하여 브레이크 안티록 효과가 발생하는 것은 앞서 도 4의 실시예에서 설명한 바와 같다. When the brake pad 86 is in close contact with the braking surface 60, as the thickness of the braking surface 60 changes, a relatively low braking force and a relatively high braking force are alternately generated to generate the brake anti-lock effect. As described in the embodiment of FIG. 4 .
즉, 브레이크 패드(86)의 모서리가 제3림유닛(60B) 및 제2림유닛(60C)을 연속하여 만나게 되는 과정에서 밀착에 따른 부하가 발생하여 브레이크 패드(86)의 모서리가 제1림유닛(60A)과 밀착되었을 때보다 제동력이 증가하게 되는 것이다.That is, in the process in which the edge of the brake pad 86 continuously meets the third rim unit 60B and the second rim unit 60C, a load due to close contact is generated so that the edge of the brake pad 86 becomes the first rim unit. The braking force is increased compared to when it is in close contact with the unit 60A.
