Description

제동기능을 구비한 사륜 운반기구{Four-wheel vehicle with braking function}Four-wheel vehicle with braking function

개시되는 내용은 제동기능을 구비한 사륜 운반기구에 관한 것으로, 더욱 상세하게는 기동차량의 정지시 제동력을 전달받아 정지될 수 있도록 하는 제동기능을 구비한 사륜 운반기구에 관한 것이다. The present disclosure relates to a four-wheel transport mechanism having a braking function, and more particularly, to a four-wheel transport mechanism having a braking function capable of being stopped by receiving braking force when the starting vehicle is stopped.

본 명세서에서 달리 표시되지 않는 한, 이 섹션에 설명되는 내용들은 이 출원의 청구항들에 대한 종래 기술이 아니며, 이 섹션에 포함된다고 하여 종래 기술이라고 인정되는 것은 아니다.Unless otherwise indicated herein, the content described in this section is not prior art to the claims of this application and is not admitted to be prior art by inclusion in this section.

사륜 운반기구, 일명 트레일러는 차량의 후미에 연결되어 구동될 수 있으며, 대용량의 화물을 운반할 수 있도록 프레임의 상부에는 적재함이 구비되고, 프레임의 하부에는 바퀴가 구비된다. The four-wheel transport mechanism, aka the trailer, can be driven by being connected to the rear of the vehicle, and a loading box is provided at the top of the frame and wheels are provided at the bottom of the frame to transport a large amount of cargo.

종래에는 사륜 운반기구에 고하중의 양수기나 기타 농업용 장비를 싣고 운반하게 되고, 트랙터나 경운기 등 기동차량의 후미에 연결하여 구동되도록 하였다. Conventionally, a four-wheel transport mechanism carries a heavy-loaded water pump or other agricultural equipment, and is driven by being connected to the rear of a starting vehicle such as a tractor or cultivator.

그러나 기동차량이 정지할 경우 사륜 운반기구도 동시에 정지할 수 있도록 제동장치가 필요하였으나 이러한 제동장치가 미비할 경우 사고 발생의 위험이 있었다. However, when the starting vehicle was stopped, a braking system was needed so that the four-wheel transport mechanism could also be stopped at the same time. However, if such a braking system was insufficient, there was a risk of an accident.

종래에는 기동차량의 제동정도를 감지하기 위한 추가 내장되어 있어서, 메인 차량의 제동력 크기에 따라 추의 움직임이 커지거나 작아지고 추의 움직임이 크면 큰 전압이 발생하고 추의 움직임이 작으면 작은 전압이 발생된다. In the related art, there is additionally built-in for detecting the braking degree of a starting vehicle, so that the movement of the weight increases or decreases depending on the magnitude of the braking force of the main vehicle, and when the movement of the weight increases, a large voltage is generated. Occurs.

그리고, 상기 발생된 전압은 트레일러 차량의 마그네틱 브레이크에 인가되어 전압의 크기에 따라 브레이크 라이닝의 확장정도가 결정되어 제동력이 트레일러 차량에 가해지도록 구성되어 있다.In addition, the generated voltage is applied to the magnetic brake of the trailer vehicle to determine the extent of expansion of the brake lining according to the magnitude of the voltage, so that the braking force is applied to the trailer vehicle.

그러나, 종래의 트레일러 차량의 제동장치에는 기동차량의 제동력이 추의 움직이는 정도에 의해 정확히 검출되지 않고, 이에 따라 기동차량과 트레일러 차량에 인가되는 제동력의 크기가 일치하지 않아 기동차량의 제동시 트레일러 차량의 제동이 부정확해지는 현상이 발생하였다.However, in the conventional braking device of a trailer vehicle, the braking force of the starting vehicle is not accurately detected by the degree of movement of the weight, and accordingly, the magnitude of the braking force applied to the trailer vehicle and the starting vehicle do not match, so the trailer vehicle during braking of the starting vehicle There was a phenomenon in which the braking of the vehicle was incorrect.

A rotating actuator 630 connected thereto;

회전작동체(630)에 연동되어 후륜의 브레이크 유닛(324)의 제동 작동을 제어하는 연동바(670);를 포함하여 구성된다. It is configured to include; interlocking with the rotating actuator 630 to control the braking operation of the brake unit 324 of the rear wheel.

작동축(610)에는 홀더(611)에 접촉 또는 이격되어 이동 간격을 제한하는 스토퍼(617)가 형성된다. A stopper 617 is formed on the operation shaft 610 to contact or space the holder 611 to limit the movement distance.

연동바(670)는 단부에 복수의 로드(680,680')가 힌지 결합되고, 각 로드(680,680')는 각기 양측 후륜의 브레이크 유닛(324)에 연결된다. The interlocking bar 670 is hinged to a plurality of rods 680 and 680' at the ends, and each rod 680 and 680' is respectively connected to the brake units 324 of the rear wheels on both sides.

브레이크 유닛(324)은 도 6의 (a)에 도시된 바와 같이, 액슬축과 연동되는 드럼(2)의 내주면에 패드가 착설된 한쌍의 라이닝(3,3a)을 결합하되 한쌍의 라이닝(3,3a)의 일측을 드럼(2)의 내부에 힌지축(32)으로 연결한다.The brake unit 324, as shown in Figure 6 (a), combines a pair of linings (3, 3a) pads are installed on the inner circumferential surface of the drum (2) interlocked with the axle shaft, but a pair of linings (3) , 3a) is connected to the inside of the drum (2) by a hinge shaft (32).

한쌍의 라이닝(3,3a)의 각 타측을 스프링(4)이 연결한다. 이 스프링(4)의 힘에 의해 한쌍의 라이닝(3,3a)이 내측으로 당겨지게 된다.A spring 4 connects each other side of the pair of linings 3 and 3a. A pair of linings 3 and 3a are pulled inward by the force of this spring 4.

로드(680,680')에 연결되는 작동편(6)이 드럼(2)의 내부에 형성되고, 작동편(6)에는 각 라이닝(3,3a)에 연결되는 제1,2연결핀(7,7a)이 각기 형성된다. The working pieces 6 connected to the rods 680 and 680' are formed inside the drum 2, and the working pieces 6 have first and second connecting pins 7 and 7a connected to each lining 3 and 3a. ) Are formed respectively.

따라서 도 4 및 도 6을 참조하면, 연동바(670)가 당겨지면 로드(680,680')가 당겨지게되고, 로드(680,680')에 연결된 작동편(6)이 회전한다. Accordingly, referring to FIGS. 4 and 6, when the interlocking bar 670 is pulled, the rods 680 and 680' are pulled, and the working piece 6 connected to the rods 680 and 680' rotates.

작동편(6)이 회전되면, 제1연결편(7)이 회전되면서 우측 라이닝(3)을 밀게 되고, 우측 라이닝(3)의 패드가 드럼(2)의 내주면에 밀착된다. When the operation piece 6 is rotated, the first connecting piece 7 is rotated to push the right lining 3 and the pad of the right lining 3 is in close contact with the inner circumferential surface of the drum 2.

이와 거의 동시에 제2연결편(7a)이 좌측 라이닝(3a)을 밀게 되고, 좌측 라이닝(3a)의 패드가 드럼(2)의 내주면에 밀착됨으로써 마찰력에 의해 제동상태가 된다. Almost simultaneously with this, the second connecting piece 7a pushes the left lining 3a, and the pads of the left lining 3a are brought into close contact with the inner circumferential surface of the drum 2, resulting in a braking state by frictional force.

이하 제동력 전달부(600)의 작동에 대해 설명한다.Hereinafter, the operation of the braking force transmission unit 600 will be described.

도 6의 (a)를 참조하면, 기동차량(100)이 정지하면 관성력에 의해 후방의 사륜 운반기구(300)가 전방으로 이동하려는 힘에 의해 신축작동부(500)의 로드(420)가 후방으로 밀려나면서 작동샤프트(220)를 밀어 후진시키게 된다. Referring to (a) of FIG. 6, when the starting vehicle 100 stops, the rod 420 of the telescopic operation unit 500 is rearward by the force that the rear four-wheel transport mechanism 300 moves forward by the inertia force. As it is pushed out, the operating shaft 220 is pushed back.

이렇게 작동샤프트(220)가 후방으로 밀려 후진되면 지지판(612)이 작동축(610)의 전단부를 접촉하면서 밀게 된다. In this way, when the operating shaft 220 is pushed backward, the support plate 612 is pushed while contacting the front end of the operating shaft 610.

이와 반대로 도 6의 (b)를 참조하면, 작동샤프트(220)가 다시 전진하면, 작동축(610)이 전방으로 이동되며 회전작동체(630)는 스프링(633)의 복원력에 의해 원래 상태로 회전하여 복귀한다. On the contrary, referring to (b) of FIG. 6, when the operation shaft 220 is advanced again, the operation shaft 610 is moved forward and the rotating actuator 630 is returned to its original state by the restoring force of the spring 633. Rotate to return.

이에 연동바(670)도 원래의 상태로 복귀하고, 브레이크 유닛(324)의 제동 작동이 오프(off) 상태가 된다. Accordingly, the interlocking bar 670 also returns to the original state, and the braking operation of the brake unit 324 is turned off.
