본 발명은 트럭의 캡 틸팅 시스템에 관한 것으로, 특히 틸팅 완료 후 전동모터의 작동이 자동으로 정지될 수 있도록 된 트럭의 캡 틸팅 시스템에 관한 것이다.The present invention relates to a cab tilting system of a truck, and more particularly to a cab tilting system of a truck, wherein the operation of the electric motor can be automatically stopped after the tilting is completed.

일반적으로 트럭의 엔진룸은 캡의 하부에 형성되어 있으며, 엔진과 각종 부 대 장치의 정비를 위하여 특히 중대형 트럭에서는 캡을 위쪽으로 들어 올리거나 내릴 수 있도록 하는 유압식 캡 틸팅 시스템이 적용되어 있다.In general, the engine room of the truck is formed in the lower part of the cab, the hydraulic cap tilting system is applied to the engine to lift and lower the cap, especially in the medium and large trucks for the maintenance of the engine and various supporting devices.

그 종래의 구조는 도 1에 도시된 바와 같이, 캡(1)의 앞쪽 단부가 프레임(2)에 힌지(3) 회동될 수 있도록 장착되어 있고, 힌지(3)점으로부터 소정 거리 이격된 위치에 캡(1)과 프레임(2)을 연결하는 틸팅실린더(4)가 설치되어 있으며, 이 틸팅실린더(4)는 전동모터(5)에 의해 작동되는 유압펌프(6)에 연결되어 있다.The conventional structure, as shown in Fig. 1, is mounted so that the front end of the cap 1 can be hinged to the frame 2, and is spaced a predetermined distance away from the hinge 3 point. Tilting cylinder (4) connecting the cap (1) and the frame (2) is provided, this tilting cylinder (4) is connected to the hydraulic pump (6) operated by the electric motor (5).

따라서, 운전자가 조작스위치(7)를 on시키면 전동모터(5)에 의해 유압펌프(6)가 작동되어 100bar 이상의 고압이 발생하게 되며, 이는 고압호스(8)를 통해 상기 틸팅실린더(4)를 작동시킴으로써 캡(1)을 들어올릴 수 있도록 되어 있다.Accordingly, when the driver turns on the operation switch 7, the hydraulic pump 6 is operated by the electric motor 5 to generate a high pressure of 100 bar or more, which causes the tilting cylinder 4 to be opened through the high pressure hose 8. By operating, the cap 1 can be lifted.

그런데, 상기 종래의 캡 틸팅 시스템에서 전동모터(5)는 항상 작업자의 조작스위치(7) 조작에 의해 수동으로 on/off되도록 되어 있다.However, in the conventional cap tilting system, the electric motor 5 is always on / off manually by manipulating the operation switch 7 of the operator.

따라서, 작업자는 항상 캡(1)의 위치를 주시하여 캡(1)의 틸팅 작동이 완료된 후 곧바로 조작스위치(7)를 off 시켜야 하는 불편함이 있었다.Therefore, the operator always had to look at the position of the cap (1) was inconvenient to turn off the operation switch 7 immediately after the tilting operation of the cap (1).

만약, 틸팅이 완료되었음에도 불구하고 부주의로 조작스위치(7)를 off시키지 않아 전동모터(5)가 계속 작동될 경우, 전동모터(5)에 무리가 발생하여 고장나게 되는 문제점이 있었다.If, even though the tilting has been completed, if the electric motor 5 continues to operate because the operation switch 7 is not inadvertently turned off, there is a problem in that the electric motor 5 is broken and broken.

또한, 작업자가 캡(1)의 위치를 주시하고 있다 하더라도, 틸팅 완료 위치를 작업자의 임의로 판단하게 되기 때문에 캡(1)이 완전한 틸팅 종료 위치에 정지하지 못하고 임의의 중간 위치에 정지될 경우에는 서포트바(9)━틸팅실린더(4)의 실린더로드 상단에 고정되어 동시에 승강되며, 상승시 몸체에 형성된 구멍에 록커가 삽입 되어 틸팅상태를 유지하게 된다.━에 무리가 가해져 휘어지는 사례가 발생하고 있다.In addition, even if the operator observes the position of the cap 1, the tilting position is determined arbitrarily by the operator. Therefore, when the cap 1 does not stop at the complete tilting end position but stops at any intermediate position, the support is supported. Bar 9 is fixed at the upper end of the cylinder rod of the tilting cylinder 4 and lifted at the same time, and the locker is inserted into the hole formed in the body to maintain the tilting state. .

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 캡이 완전히 틸팅되면 상기 전동모터로의 전력공급이 중단되어 자동적으로 전동모터가 멈추게 됨으로써 전동모터의 고장이나 서포트바의 변형을 방지할 수 있도록 된 트럭의 캡 틸팅 시스템을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the power supply to the electric motor is stopped when the cap is fully tilted to automatically stop the electric motor to prevent failure of the motor or deformation of the support bar. The object is to provide a cab tilting system for a truck that is capable of doing so.

상기와 같은 목적을 달성하기 위한 본 발명은, 캡을 틸팅시키고 틸팅 후 캡을 지지하는 서포트바를 갖춘 틸팅실린더, 이 틸팅실린더에 유압을 공급하는 유압펌프, 이 유압펌프를 작동시키는 전동모터, 이 전동모터를 on/off 시키는 조작스위치를 포함하여 이루어진 트럭의 캡 틸팅 시스템에 있어서, 상기 틸팅실린더에 서포트바의 위치를 감지하는 위치감지센서가 설치되고, 상기 조작스위치와 전원사이에 릴레이가 설치되어, 위치감지센서로부터 서포트바가 완전 틸팅 위치로 이동되었다는 신호가 전달되면 제어유니트가 상기 릴레이를 off시키도록 된 것을 특징으로 한다.The present invention for achieving the above object, the tilting cylinder having a support bar for supporting the cap after tilting the cap and tilting, a hydraulic pump for supplying hydraulic pressure to the tilting cylinder, an electric motor for operating the hydraulic pump, this electric In the cab tilting system of a truck comprising an operation switch for turning on and off the motor, a position detecting sensor for detecting the position of the support bar is installed in the tilting cylinder, a relay is installed between the operation switch and the power supply, The control unit is to turn off the relay when a signal that the support bar is moved to the fully tilted position from the position sensor.

따라서, 캡이 완전히 틸팅되면 곧바로 전동모터의 작동이 멈추게 되어 전동모터가 무리하게 작동되지 않음으로써 고장이 방지된다.Therefore, as soon as the cap is completely tilted, the operation of the electric motor is stopped and the electric motor is not forcibly operated, thereby preventing failure.

또한, 항상 캡이 완전히 틸팅된 위치에서 정지되므로 서포트바에 무리가 가해지지 않게 되어 변형이 발생하지 않게 된다. In addition, since the cap is always stopped in the fully tilted position, no strain is applied to the support bar so that deformation does not occur.                     

이하, 본 발명을 첨부된 예시도면을 참조하여 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 트럭의 캡 틸팅 시스템 구성도이다.2 is a configuration diagram of the cap tilting system of a truck according to the present invention.

종래와 동일하게 캡(1)은 앞쪽 단부가 프레임(2)에 힌지(3) 회동할 수 있도록 장착되고, 실린더의 하단이 프레임(2)에 지지되고 실린더로드의 상단이 캡(1)에 장착되어 실린더로드가 캡(1)을 밀어 올리는 틸팅실린더(4)가 구비되며, 이 틸팅실린더(4)는 전동모터(5)에 의해 작동되는 유압펌프(6)로부터 유압을 전달받아 작동된다.As in the prior art, the cap 1 is mounted so that the front end can rotate the hinge 3 to the frame 2, the lower end of the cylinder is supported on the frame 2, and the upper end of the cylinder rod is mounted on the cap 1 The cylinder rod is provided with a tilting cylinder (4) for pushing up the cap (1), the tilting cylinder (4) is operated by receiving hydraulic pressure from the hydraulic pump (6) operated by the electric motor (5).

또한, 상기 틸팅실린더(4)는 실린더로드와 연동되어 틸팅 후, 캡(1)을 지지하는 서포트바(9)를 갖추고 있다.In addition, the tilting cylinder (4) is provided with a support bar (9) for supporting the cap (1) after tilting in conjunction with the cylinder rod.

상기와 같은 구조에서 더하여 본 발명은 상기 틸팅실린더(4)의 상부에 설치되어 서포트바(9)의 위치를 감지하는 위치감지센서(10)를 포함한다.In addition to the above structure, the present invention includes a position detecting sensor 10 installed on the tilting cylinder 4 to detect the position of the support bar 9.

위치감지센서(10)는 서포트바(9)의 이동에 따른 가변 저항을 측정하여 서포트바(9)가 완전 틸팅 위치로 이동하였을 때의 저항값을 측정함으로써 캡(1)이 완전 틸팅되었는지를 제어유니트(11)가 판단할 수 있도록 하는 가변저항센서로 구성할 수 있다.The position detecting sensor 10 controls whether the cap 1 is fully tilted by measuring a variable resistance according to the movement of the support bar 9 and measuring a resistance value when the support bar 9 is moved to the fully tilted position. It can be configured as a variable resistance sensor that allows the unit 11 to determine.

또한, 위치감지센서(10)는 서포트바(9)가 완전 틸팅 위치로 이동하였을 때 위치감지센서(10)와 마주보는 지점에 감지마크(반사체 또는 구멍)를 표시하여 이를 감지함으로써 제어유니트(11)가 캡(1)의 완전 틸팅 상태를 인지할 수 있도록 하는 광센서 또는 초음파센서로 구성할 수도 있다.In addition, the position detecting sensor 10 displays a detection mark (reflector or hole) at a point facing the position detecting sensor 10 when the support bar 9 moves to the fully tilting position, thereby detecting the control unit 11. ) May be configured as an optical sensor or an ultrasonic sensor to recognize the complete tilting state of the cap (1).

즉, 당업자라면 다양한 센서를 이용하여 서포트바(9)의 완전 틸팅 위치로의 이동을 감지하는 위치감지센서를 구현하여 적용할 수 있음은 물론이다.That is, those skilled in the art can implement and apply a position detection sensor for detecting the movement of the support bar 9 to the fully tilted position by using various sensors.

한편, 본 발명은 종래의 조작스위치(7)와 전원의 사이에 설치되는 릴레이(12) 및 위치감지센서(10)로부터 신호를 받아들여 완전 캡 틸팅 상태임을 판단하는 상기 제어유니트(11)를 포함한다.On the other hand, the present invention includes the control unit 11 for receiving a signal from the relay 12 and the position sensor 10 installed between the conventional operation switch 7 and the power supply to determine the complete cap tilting state. do.

상기 제어유니트(11)는 위치감지센서(10)로부터 서포트바(9)가 캡 완전 틸팅 위치로 상승되었다는 신호가 전달되면, 상기 릴레이(12)를 off상태로 제어한다.The control unit 11 controls the relay 12 to be turned off when a signal is transmitted from the position sensor 10 that the support bar 9 is raised to the cab full tilting position.

이제 본 발명의 작용 및 효과를 설명한다.The operation and effects of the present invention will now be described.

운전자가 조작스위치(7)를 on시키면, 전동모터(5)가 작동되어 유압펌프(6)가 작동되고, 이에 의해 발생된 유압이 틸팅실린더(4)에 전달되어 캡(1)이 상승된다.When the driver turns on the operation switch 7, the electric motor 5 is operated to operate the hydraulic pump 6, and the generated hydraulic pressure is transmitted to the tilting cylinder 4 so that the cap 1 is raised.

이때 틸팅실린더(4)의 실린더로드에 연동되어 서포트바(9)가 동시에 상승되며, 서포트바(9)가 설정 위치 즉, 캡 완전 틸팅 위치로 이동되면 상기 위치감지센서(10)는 이를 감지하여 감지신호를 제어유니트(11)에 전달한다.At this time, the support bar (9) is simultaneously raised in conjunction with the cylinder rod of the tilting cylinder (4), when the support bar (9) is moved to the set position, that is, the cap full tilting position, the position detecting sensor (10) detects this The detection signal is transmitted to the control unit 11.

신호를 전달받은 제어유니트(11)는 캡(1)이 완전하게 틸팅되었음을 인지하고, 즉시 상기 릴레이(12)를 off 시킨다.The control unit 11 receiving the signal recognizes that the cap 1 is completely tilted and immediately turns off the relay 12.

이에 전동모터(5)로의 전력공급이 중단되게 된다.As a result, the power supply to the electric motor 5 is stopped.

즉, 캡(1)이 완전 틸팅 위치로 상승됨과 동시에 전동모터(5)의 작동이 중지됨으로써 캡(1)이 완전 틸팅 위치로 상승되었음에도 불구하고 전동모터(5)의 작동이 불필요하게 지속되는 현상이 발생하지 않게 된다.That is, the cap 1 is raised to the fully tilted position and at the same time the operation of the electric motor 5 is stopped so that the operation of the electric motor 5 unnecessarily continues even though the cap 1 is raised to the fully tilted position. This will not happen.

따라서, 무리한 작동에 의한 전동모터(5)의 고장이 발생하지 않게 되는 효과가 있으며, 유압펌프(6) 또한 보호할 수 있게 된다. Therefore, there is an effect that the failure of the electric motor 5 due to excessive operation does not occur, it is possible to protect the hydraulic pump (6).                     

한편, 상기와 같이 캡(1)의 틸팅 정지가 항상 완전한 틸팅 위치로의 이동 후에 이루어지게 됨으로써 종래와 같이 작업자의 임의 판단에 의하여 캡(1)이 임의 위치에 멈춰 서지 않게 되어 서포트바(9)에 무리가 가해지지 않음으로써 서포트바(9)가 휘어지는 현상이 발생하지 않게 된다.On the other hand, as described above, the tilting stop of the cap 1 is always made after the movement to the complete tilting position, so that the cap 1 does not stop at an arbitrary position by the operator's arbitrary judgment as in the prior art, and thus the support bar 9 is supported. Since the force is not applied to the support bar 9, the phenomenon that the support bar 9 does not occur.

이상 설명한 바와 같이 본 발명에 따르면, 캡 틸팅 완료 후, 전동모터가 자동으로 작동 정지됨으로써 전동모터가 무리하게 작동되어 고장나는 현상이 해소된다.As described above, according to the present invention, after the cap tilting is completed, the electric motor is automatically stopped by the operation of the electric motor forcibly operated to eliminate the phenomenon of failure.

또한, 캡은 항상 완전한 틸팅 위치에서 정지하게 됨으로써 불완전한 위치에 정지함으로써 발생하는 서포트바 휨 현상이 발생하지 않게 되는 효과가 있다.In addition, since the cap is always stopped in the complete tilting position, there is an effect that the support bar bending phenomenon caused by stopping in the incomplete position does not occur.
