Friction heat is generated in the disk body, and radiated promptly through the wall part having the high thermal conductivity. Coning is reduced, and flexibility of the wall part is improved with forming the aluminum wall part. Judder is reduced with decreasing coning, and braking efficiency is improved with reducing the weight of the disk brake.

Description

분리형 브레이크 디스크{A separation type brake disk}Separation type brake disk

본 발명은 차량용 디스크 브레이크에 관한 것으로, 특히 디스크 브레이크의 열변형에 의한 커닝(coning)값을 줄이기 위해 디스크 바디와 월부를 두 부분으로 분리하고 월부의 재질을 열전도 특성이 우수한 알루미늄으로 채용함에 따라 월부의 유연성이 향상되어 커닝값이 줄어듬은 물론, 디스크 브레이크의 중량 또한 가벼워져 제동성능이 향상되도록 된 분리형 브레이크 디스크에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc brake for a vehicle, and in particular, in order to reduce the kerning value due to thermal deformation of the disc brake, the disc body and the wall part are separated into two parts, and the wall part is made of aluminum having excellent thermal conductivity. The present invention relates to a detachable brake disc in which the flexibility of the negative part is reduced, the kerning value is reduced, and the weight of the disc brake is also lighter, thereby improving the braking performance.

주지된 바와 같이 브레이크 디스크는 제동시 마찰력에 의해 열변형이 발생하게 되고 이 열변형에 의해 발생되는 커닝(coning)은 브레이크 저더(judder)와 마찰재 편마모를 유발시키게 된다.As is well known, brake discs are subject to thermal deformation due to frictional forces during braking and coning caused by thermal deformation causes brake judder and friction material wear.

한편 종래에는 도 4에 도시된 것과 같이, 브레이크 디스크(10)는 월부(12)와 디스크 바디(11)가 일체형으로 되어 있고, 대개 주물과 같은 재질로 제작된다. 따라서 도 5 및 도 6에 도시된 커닝 측정치와 같이 브레이크 디스크(10)는 열변형에 의한 커닝(coning)이 발생하게 되어 브레이크 저더와 마찰재의 편마모를 유발하게 되는 심각한 문제점이 발생하게 된다.On the other hand, conventionally, as shown in FIG. 4, the brake disc 10 has a wall portion 12 and a disc body 11 integrated, and is usually made of a casting-like material. Therefore, as shown in the kerning measurements shown in FIGS. 5 and 6, the brake disc 10 may have a coning caused by thermal deformation, thereby causing a serious problem of causing uneven wear of the brake judder and the friction material.

상기와 같은 커닝 현상을 최소화기 위한 설계인자 중, 가장 큰 인자는 월(wall)부의 유연성이다. 상기 월부의 유연성을 부여하기 위해, 월부의 높이를 조절하는 것은 차량의 오프세트(off-set)와 연관되어 있어 한계가 있다.Among the design factors for minimizing the kerning phenomenon as described above, the biggest factor is the flexibility of the wall portion. In order to give the flexibility of the moon, adjusting the height of the moon is limited as it is associated with the off-set of the vehicle.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 디스크 바디와 월부를 두 부분으로 분리하고 이 연결부에는 보강커버를 적용하며, 월부의재질을 열전도 특성이 우수한 알루미늄으로 채용함에 따라 월부의 유연성이 향상되어 커닝값이 줄어듬은 물론, 디스크 브레이크의 중량 또한 가벼워져 제동성능이 향상되도록 된 분리형 브레이크 디스크를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the above problems, and separates the disk body and the wall into two parts and applies a reinforcement cover to the connection portion, and by adopting the material of the wall as aluminum having excellent thermal conductivity, The purpose of the present invention is to provide a detachable brake disc in which the flexibility is improved and the kerning value is reduced, as well as the weight of the disc brake is also lightened to improve the braking performance.

상기와 같은 목적을 달성하기 위한 본 발명은 알루미늄 재질로 된 월부와, 주물 재질로 된 디스크 바디로 분리되고, 상기 월부와 디스크 바디의 연결부에 적용되는 보강커버로 구성되어되고, 상기 보강커버는 체결볼트에 의해 체결되어지되, 이 보강커버는 주물재질을 사용하여 연결부의 강성을 보강하게 되는 것을 특징으로 한다.The present invention for achieving the above object is separated into a wall portion made of aluminum material, and a disk body made of a cast material, consisting of a reinforcement cover applied to the connection portion of the wall portion and the disk body, the reinforcement cover is fastened It is fastened by bolts, the reinforcement cover is characterized in that to reinforce the rigidity of the connection using the casting material.

따라서 상기 디스크 바디에서 발생되는 마찰열이 높은 열전도 계수를 갖는 월부를 통하여 외부로 빠르게 전달될 수 있어, 코닝이 감소할 수 있게 된다. 이것에 의해 브레이크 저더를 감소시킬 수 있음은 물론, 디스크 브레이크의 중량 또한 가벼워져 제동성능이 향상되는 것이다.Therefore, the frictional heat generated in the disk body can be quickly transmitted to the outside through the wall portion having a high thermal conductivity coefficient, so that Corning can be reduced. As a result, the brake judder can be reduced, and the weight of the disc brake is also lightened, thereby improving the braking performance.

도시된 바와 같이, 본 발명은 알루미늄 재질로 된 월부(2)와, 주물 재질로된 디스크 바디(4)로 분리되고, 상기 월부(2)와 디스크 바디(4)의 연결부에 적용되는 원형고리형태의 보강커버(3)로 구성되어진다. 여기서 상기 보강커버(3)는 체결볼트(3-1)에 의해 체결되어지되, 이 보강커버(3)는 주물재질을 사용하여 연결부의 강성을 보강하게 된다.As shown, the present invention is divided into a wall portion 2 made of aluminum and a disk body 4 made of a cast material, and a circular ring shape applied to the connection portion of the wall portion 2 and the disk body 4. It consists of a reinforcement cover (3). Wherein the reinforcement cover 3 is fastened by the fastening bolt (3-1), the reinforcement cover (3) is to reinforce the rigidity of the connecting portion using the casting material.

따라서 상기 디스크 바디(4)에서 발생되는 마찰열이 높은 열전도 계수를 갖는 월부(2)를 통하여 외부로 빠르게 전달될 수 있어, 코닝이 감소할 수 있게 된다. 이는 전산 해석상 코닝값의 20%를 감소할 수 있다. 부연하자면, 디스크의 마찰면은 가능하면 많은 열용량을 확보하여야 되고 월부는 주위 장착 부품과 대기중중으로 빠른 열전달을 해주어야 된다.Therefore, the frictional heat generated in the disk body 4 can be quickly transmitted to the outside through the wall portion 2 having a high thermal conductivity coefficient, so that corning can be reduced. This may reduce 20% of Corning's value in computational analysis. In other words, the friction surface of the disc should have as much heat capacity as possible, and the lugs should provide rapid heat transfer to the surrounding mounting components and to the atmosphere.

디스크 브레이크는 회전관성 부품으로, 중량이 절감되면 제동성능이 우수해진다. 즉, 본 발명에 적용되는 디스크브레이크 월부(2)의 재질이 비교적 중량이 가벼운 알루미늄이기 때문에 브레이크 디스크의 전체 중량이 감소시키는 결과로 이어져, 브레이크의 제동성능이 향상되는 효과도 얻을 수 있다.The disc brake is a rotary inertia component, and when the weight is reduced, the braking performance is excellent. That is, since the material of the disc brake wall portion 2 applied to the present invention is aluminum, which is relatively light in weight, the total weight of the brake disc is reduced, so that the braking performance of the brake can be improved.

또한 알루미늄 재질 특성상, 큰 댐핑 성능에 의하여 소음 진동이 저감되는 효과도 있다.In addition, due to the characteristics of the aluminum material, there is also an effect that noise vibration is reduced by the large damping performance.

이상과 같이 상세하게 설명한 본 발명에 의하면, 디스크 바디와 월부를 두 부분으로 분리하고 이 연결부에는 보강커버를 적용하며, 월부의 재질을 열전도 특성이 우수한 알루미늄으로 채용함에 따라 월부의 유연성이 향상되어 커닝값이 줄어들어 브레이크 저더를 감소시킬 수 있음은 물론, 디스크 브레이크의 중량 또한 가벼워져 제동성능이 향상되는 효과가 있다.According to the present invention described in detail as described above, the disk body and the wall portion is separated into two parts, the reinforcement cover is applied to the connection portion, and the flexibility of the wall portion is improved by employing the material of the wall portion as aluminum having excellent thermal conductivity characteristics. In addition to reducing the value, the brake judder can be reduced, as well as the weight of the disc brake is also lightened, thereby improving the braking performance.
