그런데 상기 완충장치로서는 기름등의 유체(流體)의 유동저항에 의해서 감쇄작용을 발휘하는 쇼크업서어버와 외부진동을 탄성에너지로서 축적하는 스프링을 함께 갖추어서 유니트 화(化)된 완충기가 채택되고 있다. 그런데 근래 2륜차에 대한 경량화의 요구는 끈질기며, 이 요구는 이 종류의 완충장치에 대하여도 경량화가 요구되고 있다.However, as the shock absorber, a shock absorber having a shock absorber exerted by the flow resistance of a fluid such as oil and a spring that accumulates external vibration as elastic energy are unitized to adopt a shock absorber. have. However, in recent years, the demand for weight reduction for two-wheeled vehicles has been persistent, and this demand has also been required for weight reduction for this type of shock absorber.

본 발명자는 이러한 요구에 응하고저 본 발명을 이룬 것으로 그 목적으로 하는 바는 차체와 후륜지지부재를 완충장치를 통하여 연결하는 후륜현가장치에 있어서 상기 완충기를 차체프레임과 상기 후륜지지부재간에 장치한 링상 탄성밴드를 포함하여 구성하므로써 중량경감, 승차감의 향상을 도모할 수 있도록 한 2륜차용 후륜현가장치를 제공함에 있다.The inventors of the present invention have achieved the present invention, and an object thereof is to provide a shock absorber disposed between the vehicle body frame and the rear wheel support member in a rear wheel suspension for connecting the vehicle body and the rear wheel support member through a shock absorber. The present invention provides a rear wheel suspension system for a two-wheeled vehicle that includes a ring-shaped elastic band to reduce weight and improve ride comfort.

다음에 본 발명의 바람직한 1실시예를 첨부도면에 의거하여 상술한다.Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 관한 후륜현가장치를 장착하여 이루어진 자동 2륜차의 측면도, 제2도는 탄성밴드의 장설상태를 표시한 동 자동2륜차의 부분확대 측면도, 제3도는 동 투시도, 제4도는 탄성밴드의 투시도이다.1 is a side view of an automatic two-wheeled vehicle equipped with a rear wheel suspension according to the present invention, and FIG. 2 is a partially enlarged side view of the automatic two-wheeled vehicle showing the installation state of an elastic band, and FIG. 3 is a perspective view thereof, and FIG. 4 is an elasticity. Perspective view of the band.

제1도에 표시한 자동2륜차(1)에 있어서 2는 차체프레임이며 이 차체프레임(2)상에는 엔진(3)이 장착되며 엔진(3)에는 카아뷰레터(4) 및 에어클리이너(5)가 연결되어 있다. 또 상기 엔진(3)의 상방에는 연료탱크(6)가 설치되었으며 이 연료탱크(6)의 후방에는 좌석시이트(7)가 또한 좌석시이트(7)의 양측 하방에는 사이드커버(8)가 각각 설치되어 있다.In the two-wheeled vehicle 1 shown in FIG. 1, 2 is a body frame, and the engine 3 is mounted on the body frame 2, and the carburetor 4 and the air cleaner 5 are mounted on the engine 3. ) Is connected. In addition, a fuel tank 6 is installed above the engine 3, and a seat seat 7 is installed at the rear of the fuel tank 6, and side covers 8 are respectively installed at both sides of the seat seat 7 below. It is.

한편 상기 차체프레임(2)의 상방 전단에는 헤드파이프(9)가 고착되며 이 헤드파이프(9)에는 톱브리지(10)와 보텀브리지(11)이 일체로 연결하는 스템샤프트가 자유롭게 회전하도록 끼워지고 상기 톱브리지(10)상에는 핸들(12)이 고정되어 있다.On the other hand, the head pipe (9) is fixed to the upper front end of the body frame (2), the head shaft (9) is fitted so that the stem shaft which the top bridge 10 and the bottom bridge (11) is integrally connected to rotate freely. The handle 12 is fixed on the top bridge 10.

또 상기 헤드파이프(9)의 전방에는 프런트포오크(13)의 상부가 톱브리지(10)와 보텀브리지(11)간에 끼워넣어 연결되며 이 프런트포오크(13)의 하단에는 전륜(14)이 자유로이 회전할 수 있게 지지되어 있다. 또한 15는 프런트펜더이다.In addition, the front of the head pipe (9) is connected to the upper portion of the front fork 13 is inserted between the top bridge 10 and the bottom bridge 11, the front wheel 14 is freely rotated to the lower end of the front fork 13 It is supported. Also 15 is the front fender.

또 차체의 거의 중앙하부의 차체프레임(2)에는 브래킷(16)을 통하여 후륜지지부재인 리어포오크(17)의 전단이 요동자유로 추착되어 있으며 또 리어포오크(17)의 후단에는 후륜(19)이 회전자유로 지지되어 있다. 그리고 차체와 상기 리어포오크(17)간은 도시한 바와 같이 쇼크업서어버(20)로 연결되어 있다. 이 쇼크업서어버(20)은 예컨대 내부에 유체를 봉입(封入)하고 이 유체가 밸브등을 통과할 때의 유동저항으로써 소요감쇠력을 발생시키는 것이며 이는 감쇠력 기능만을 지니고 종래의 완충기와 같이 스프링 기능을 함께 지닌 것과는 다르게 되어 있어 따라서 이 쇼크업서어버(20)는 종래의 완충기에 비하여 경량이다.In addition, the front end of the rear fork 17, which is the rear wheel support member, is freely swayed through the bracket 16 in the body frame 2 near the center of the vehicle body, and the rear wheel 19 is located at the rear end of the rear fork 17. This rotational freedom is supported. The vehicle and the rear fork 17 are connected to the shock absorber 20 as shown. The shock absorber 20 encloses a fluid inside, for example, and generates a required damping force as a flow resistance when the fluid passes through a valve or the like. This shockup server 20 is therefore lighter than a conventional shock absorber.

한편 리어포오크(17)와 차체프레임(2)간에는 도시한 바와 같이 링상의 탄성밴드(21)가 가설되어 있다. 즉 리어포오크(17)의 전방측 상부에는 제2도 및 제3도에 상세히 표시한 바와 같이 브래킷(22, 22)이 세워서 설치되며 이 양 브래킷(22, 22)간에는 축(23)이 가설되어 있다.On the other hand, a ring-shaped elastic band 21 is hypothesized between the rear fork 17 and the body frame 2 as shown. That is, as shown in detail in FIGS. 2 and 3, the front upper portion of the rear fork 17 is provided with brackets 22 and 22 upright, and a shaft 23 is installed between the brackets 22 and 22. have.

한편 차체프레임(2)의 하방 각부간(角部間)에는 상기 축(23)에 대하여 평행으로 또 한쪽의 축(24)이 가설되며 이들 앙 축(23, 24)간에 상기 탄성밴드(21)가 장설되어 있다. 탄성밴드(21)는 제4도에 표시한 바와 같이 띠모양으로 성형된 1개의 탄성체를 연속적으로 포개맞추어서 접착하므로써 링상으로 성형되며 충분한 탄성 및 강도를 갖추고 있으며 또 경량이기도 하다. 또한 제1 도면중 25는 리어펜더이다.On the other hand, one of the shafts 24 is provided in parallel between the lower portions of the body frame 2 in parallel with the shaft 23, and the elastic band 21 is formed between these angular shafts 23 and 24. Is established. As shown in FIG. 4, the elastic band 21 is formed in a ring shape by successively overlapping and bonding one elastic body formed in a strip shape, and has sufficient elasticity and strength, and is also lightweight. 25 in the first drawing is a rear fender.

그리하여 상기 탄성밴드(21)는 차체 및 승무원의 중량을 그 탄성력에 의해서 부담하며 따라서 이 탄성밴드(21)는 상시 인장상태에 있다.Thus, the elastic band 21 bears the weight of the vehicle body and the crew by its elastic force, so that the elastic band 21 is always in tension.

그런데 주행중 후륜(19)이 고르지 못한 노면에 의해서 상하운동하여도 이 진동은 탄성밴드(21)의 완충작용에 의해서 완화됨과 동시에 쇼크업서어버(20)의 감쇄작용에 의해 신속하게 흡수완화되기 때문에 후륜으로부터의 충격, 진동이 직접 차체측에 전파되는 일이 없으며 따라서 본 현가장치는 종래의 완충기와 마찬가지로 승차감, 조종안정성 향상에 이바지할 수가 있다.However, even if the rear wheel 19 moves up and down by the uneven road surface while driving, the vibration is alleviated by the buffering action of the elastic band 21 and absorbed by the damping action of the shock absorber 20. The shocks and vibrations from the rear wheels do not directly propagate to the vehicle body side. Therefore, the suspension system can contribute to the improvement of ride comfort and steering stability, as in the conventional shock absorber.

종래의 완충기는 감쇄기능을 가진 통상의 완충기(20)을 둘러싸고 있는 코일스프링이 비치되어 있었다. 이 때문에 코일스프링의 전체외경이 크게 되고 상당히 큰 중량을 갖게 되어 있었다. 더우기 완충기 자체가 코일스프링때문에 더욱 크게되어 배치하기 위하여 넓은 공간이 필요하였다.The conventional shock absorber was provided with a coil spring surrounding the conventional shock absorber 20 having a damping function. For this reason, the total outer diameter of the coil spring became large and had a very large weight. Moreover, the shock absorber itself became larger due to the coil spring, which required a large space for placement.

본 발명의 링상 탄성밴드는 쇼크업서어버(20)에 영향을 받지 않기 때문에 종래의 코일스프링에 비교하여 소형화할 수 있다. 따라서 중량을 경감시킬 수 있다. 또 쇼크업서어버(20)는 종래의 코일스프링을 부착한 것보다 배치하기 위한 공간을 작게하여도 된다.Since the ring-shaped elastic band of the present invention is not affected by the shock absorber 20, the ring-shaped elastic band can be downsized as compared with the conventional coil spring. Therefore, the weight can be reduced. In addition, the shock absorber 20 may have a smaller space for disposition than a conventional coil spring.

한편 본 장치에 있어서는 종래의 완충기에 채택되고 있던 금속성의 스프링을 폐지하고 이보다도 경량한 탄성밴드(21)를 채택하였기 때문에 차체전체의 대폭적인 중량경감이 가능하게 되어 주행성능상 유리하게 될뿐만 아니라 스프링 하하중(下荷重)의 경감에 의한 승차감의 더 한층의 향상을 도모할 수가 있다.On the other hand, this device eliminates the metallic spring used in the conventional shock absorber and adopts a lighter elastic band 21, thereby enabling a significant weight reduction of the entire vehicle body. It is possible to further improve the riding comfort by reducing the load.

이상 설명한 실시예에 있어서는 완충장치를 쇼크업서어버와 탄성밴드로 구성하였으나 경우에 따라서는 탄성밴드의 히스테리시스 특성을 감쇄효과에 이용하여 쇼크업서어버를 생략할 수도 있으며 이런 경우에는 상술한 효과는 더욱 현저하게 된다.In the above-described embodiment, the shock absorber is composed of a shock absorber and an elastic band. However, in some cases, the shock absorber may be omitted by using the hysteresis characteristics of the elastic band for the damping effect. More remarkable.

이상의 설명에서 명백한 바와 같이 본 발명에 의하면 차체와 후륜지지부재를 완충장치를 통하여 연결하는 2륜차용 후륜현가장치에 있어서 상기 완충기를 차체프레임과 상기 후륜지지부간에 장설한 링상 탄성밴드를 포함하여 구성하였기 때문에 2륜차의 중량경감 승차감의 향상을 도모할 수가 있다.As apparent from the above description, according to the present invention, in the rear wheel suspension device for a two-wheeled vehicle connecting the vehicle body and the rear wheel support member through a shock absorber, the shock absorber includes a ring-shaped elastic band provided between the body frame and the rear wheel support part. Therefore, the weight reduction of the two-wheeled vehicle can be improved.
