Description

동력 절단용 금속벨트Metal Belts for Power Cutting

본 발명은 벨트에 관한 것으로서, 특히 내구성을 요망하는 무단 변속기의 동력 전달용으로 사용되는 금속 벨트에 관한 것이다.The present invention relates to belts, and more particularly to metal belts used for power transmission of continuously variable transmissions.

일반적으로 벨트는 동력 전달용으로 많이 사용되고 있으며, 이와같은 벨트는 그 재질에 따라 고무 벨트와 금속 벨트로 구별되고 있다.In general, belts are widely used for power transmission, and such belts are classified into rubber belts and metal belts according to their materials.

이와같은 벨트중 특히 금속 벨트는 고무 벨트에 비하여 열에 강하고 장시간 사용할 때에도 그 내구성(耐久性)이 열화되지 않기 때문에 고열이 발생되는 자동차의 무단 변속기 등에 적용되고 있다.Among these belts, especially metal belts are applied to continuously variable transmissions of automobiles, which are more resistant to heat and do not degrade their durability even when used for a long time.

제1도에는 이와같이 무단 변속기의 동력 전달용으로 사용되고 있는 금속벨트가 도시되어 있다.FIG. 1 shows a metal belt which is thus used for power transmission of the continuously variable transmission.

이는 크게 서로 나란하게 설치되는 한쌍의 링 밴드(ring band; 1,2)와, 이 링 밴드(1,2) 사이에 끼워 삽입되는 다수의 블록(block; 3)으로 대별된다.This is roughly divided into a pair of ring bands 1 and 2 which are installed in parallel with each other, and a plurality of blocks 3 inserted between the ring bands 1 and 2.

이때 블록(3)의 상세한 구조를 보면, 양측면에 링 밴드(1,2)가 끼워 삽입될 수 있도록 양측면에 홈(3a)이 형성된 화살표 형상의 몸체(3b)와, 이 몸체(3b)의 하부로부터 링 밴드(1,2)의 하면에 전면적으로 밀착되도록 역T형상으로 연장 형성되는 결합편(3c)으로 이루어져 있다.At this time, the detailed structure of the block 3, the arrow-shaped body (3b) formed with grooves (3a) on both sides so that the ring band (1, 2) can be inserted into both sides, and the lower part of the body (3b) It consists of a coupling piece (3c) extending in an inverted T shape so as to be in close contact with the entire surface of the ring band (1, 2) from.

그러나 이와같은 구성을 갖는 종래 금속 벨트는, 다음에 열거하는 많은 문제점을 내재하고 있다.However, the conventional metal belt having such a configuration has many problems listed below.

첫째, 무단 변속기의 변속과정에서 속도의 가감(加減)에 따라 풀리(미도시) 접촉되는 접촉면에서 마찰소음이 심하게 발생되는 문제점이 야기된다. 이와같은 문제점은 링 밴드(1,2)에 삽입되어 있는 다수의 블록(3)들이 서로 미세하나마 마찰 접촉됨에 따라 발생된다.First, the friction noise is severely generated at the contact surface of the pulley (not shown) as the speed increases or decreases during the speed change of the continuously variable transmission. This problem occurs as a plurality of blocks 3 inserted in the ring bands 1 and 2 are in friction contact with each other.

둘째, 다수의 블록(3)들간에 미세하나마 틈새가 존재하는 것에 의해 다수의 블록(3)들이 서로 일체화 되지못함으로써 변속과정에서 슬립(slip)이 발생되어 변속효율이 떨어지는 문제점이 발생된다.Second, due to the presence of a small gap between the plurality of blocks (3), the plurality of blocks (3) are not integrated with each other, the slip (slip) is generated in the shifting process is a problem that the transmission efficiency is lowered.

셋째, 블록(3)들을 얇은 박판상으로 형성하여야 하는 것은 물론이고, 상호간의 접촉면을 정밀가공하여야 함으로써 작업성의 저하와 단가상승을 초래하는 문제점이 야기된다.Third, not only the blocks 3 should be formed in a thin thin plate shape, but also the contact surfaces of each other must be precisely processed, which causes problems of deterioration of workability and cost increase.

본 발명은 이와같은 종래의 제반 문제점을 해결하기 위하여 안출된 것으로서, 제작이 용이하고, 특히 변속과정에서 슬립이 발생되지 않으며 소음을 억제할 수 있는 금속벨트를 제공함에 그 목적이 있다.The present invention has been made to solve such a conventional problem, it is an object to provide a metal belt that is easy to manufacture, in particular, slip does not occur in the shifting process and can suppress the noise.

이와같은 목적을 달성하기 위하여 본 발명에 따른 동력 전달용 금속벨트는, 서로 소정간격을 유지한채 평행하게 설치되는 한쌍의 링 밴드와, 이 링 밴드에 체결되는 다수의 블록을 갖는 동력 전달용 금속벨트에 있어서, 상기 블록은, 상기 링 밴드가 끼워 삽입되도록 그 양측면에 홈이 형성된 몸체와; 상기 몸체의 일측면으로부터 그 내면에 끼움홈을 형성하도록 U자형으로 연장 형성되는 결합편과; 상기 결합편과 대향되는 몸체의 타측면으로부터 수직 하방으로 연장 형성되며, 인접된 블록의 결합편에 형성된 끼움홈에 끼워 삽입되는 체결편;으로 이루어진 것을 그 특징으로 한다.In order to achieve the above object, the power transmission metal belt according to the present invention includes a pair of ring bands installed in parallel while maintaining a predetermined distance from each other, and a power transmission metal belt having a plurality of blocks fastened to the ring band. The block may include: a body having grooves formed at both sides thereof so that the ring band is inserted; A coupling piece extending in a U shape to form a fitting groove in an inner surface thereof from one side of the body; Characterized in that consisting of; fastening piece is formed extending from the other side of the body facing the coupling piece vertically downward, inserted into the fitting groove formed in the coupling piece of the adjacent block.

이와같은 본 발명의 특징적인 구성 및 이에따른 작용효과는 후술하는 첨부된 도면을 참조한 발명의 상세한 설명을 통해 더욱 명확해 질 것이다.Such a characteristic configuration and the resulting effects of the present invention will become more apparent from the following detailed description of the invention with reference to the accompanying drawings.

제2도는 본 발명에 따른 금속 벨트의 사시도이고, 제3도는 하나의 블록을 발췌하여 도시한 확대 사시도이며, 제4도는 제3도의 A-A선 단면도이다.FIG. 2 is a perspective view of a metal belt according to the present invention, FIG. 3 is an enlarged perspective view showing an extract of one block, and FIG. 4 is a sectional view taken along the line A-A of FIG.

이에 도시된 바와 같이 본 발명에 따른 금속 벨트는, 서로 소정간격 유지한채 평행하게 설치되는 한쌍의 링 밴드(ring band; 10,20)와, 이 링 밴드(10, 20) 사이로 끼워 삽입되어 서로 밀착되는 다수의 블록(block; 30)을 구비한다.As shown therein, the metal belt according to the present invention includes a pair of ring bands 10 and 20 installed in parallel while maintaining a predetermined distance from each other, and is inserted into the ring bands 10 and 20 to closely adhere to each other. And a plurality of blocks 30 to be made.

이때 전술한 블록(30)은 실질적으로 본 발명의 특징적인 요소를 갖고 있는 것으로서 그 상세한 구조를 보면, 크게 몸체(31)와 결합편(32) 및 체결편(33)으로 대별된다.At this time, the block 30 described above has substantially the characteristic elements of the present invention, and the detailed structure thereof is largely classified into a body 31, a coupling piece 32, and a fastening piece 33.

몸체(31)의 양측면에는 링 밴드(10, 20)의 각 대응되는 내측면이 끼워 삽입될 수 있도록 홈(31a)이 형성된다.Grooves 31a are formed on both side surfaces of the body 31 so that the corresponding inner surfaces of the ring bands 10 and 20 can be inserted.

결합편(32)은, 몸체(31)의 일측면으로부터 대략“U”자형으로 연장 형성되는 것으로써 그 내면에 끼움홈(32a)이 형성된다.Coupling piece 32 is formed to extend substantially in a "U" shape from one side of the body 31, the fitting groove 32a is formed on the inner surface.

한편, 체결편(33)은 결합편(32)과 대향되는 측의 몸체(31) 타측면으로부터 수직 하방으로 연장 형성되는 것으로서, 인접된 블록(30)의 결합편(32)에 형성된 끼움홈(32a)에 끼워 삽입되어진다.On the other hand, the fastening piece 33 is formed to extend vertically downward from the other side of the body 31 on the side opposite to the coupling piece 32, the fitting groove formed in the coupling piece 32 of the adjacent block 30 ( It is inserted into 32a).

따라서 이 체결편(33)의 연장 길이는 결합편(32)에 비하여 상대적으로 짧게 연장 되어야 할 것이다.Therefore, the extension length of the fastening piece 33 should be extended relatively short compared to the coupling piece (32).

이와같이 구성된 본 발명은, 다수의 블록(30)을 그 몸체(31)에 형성된 홈(31a)을 통해 한쌍의 링 밴드(10, 20)에 끼워 삽입한다.According to the present invention configured as described above, the plurality of blocks 30 are inserted into the pair of ring bands 10 and 20 through the grooves 31a formed in the body 31.

이때 다수의 블록(30)들은 결합편(32)에 형성된 끼움홈(32a)에 인접된 블록(30)의 체결편(33)이 끼워 삽입되어 상호 일체화되게 된다. 즉, 상호간의 틈새가 발생되지 않게된다.At this time, the plurality of blocks 30 are inserted into the fastening piece 33 of the block 30 adjacent to the fitting groove 32a formed in the coupling piece 32 to be integrated with each other. In other words, there is no gap between them.

따라서 무단 변속기의 변속과정에서 즉, 속도의 가감에 따라 슬립이 발생되지 않게되는 물론이고, 소음이 발생되지 않게된다.Therefore, during the shifting of the continuously variable transmission, that is, slip is not generated as the speed increases or decreases, and noise is not generated.

한편, 이와같은 본 발명은 자동차 무단 변속기의 동력 전달용으로 사용되는 것을 예시하여 설명하였지만 이에 한정되지 않으며, 내구성을 요하는 각종 기계장치의 동력 전달용으로 용이하게 사용가능한 것은 당업자라면 충분히 주지할 수 있는 사실일 것이다.On the other hand, the present invention has been described by way of example to be used for power transmission of the continuously variable transmission of the automobile, but is not limited thereto, it can be sufficiently known to those skilled in the art that it can be easily used for power transmission of various mechanical devices that require durability. It will be true.

상술한 바와 같이 본 발명에 따른 동력 전달용 금속벨트에 의하면, 링 밴드에 체결되는 블록간에 틈새가 발생되지 않아 동력 전달효율을 향상시킬 수 있으며, 특히 소음 발생을 억제할 수 있는 효과가 있다. 또한 그 가공이 용이하여 작업성의 향상과 단가절감을 꾀할 수 있는 이점이 있다.As described above, according to the power transmission metal belt according to the present invention, a gap does not occur between blocks fastened to the ring band, thereby improving power transmission efficiency, and in particular, there is an effect of suppressing noise generation. In addition, the processing is easy, there is an advantage that can be improved workability and cost reduction.
