Abstract

PURPOSE: A tilting safety circuit of a commercial vehicle is provided to tilt a cap of the vehicle regardless of the on/off state of a transmission neutral switch when a starting key is turned on after executing pneumatic parking braking. CONSTITUTION: In a tilting safety circuit of a commercial vehicle, a tilt power relay(130) is excited and a tilt relay load contact is turned on if a parking switch(100), a tilt switch(110), and a transmission interlock switch are turned on when power is applied through operation of a starting key by a user to tilt a cap of the vehicle. And power is supplied to a tilt motor(150) and the cap is tilted. The tilting safety circuit tilts the cap regardless of the power and the on/off state of a gear neutral switch. If a pneumatic parking brake is released during starting of the engine, the tilting safety circuit cuts off power and produces a warning sound the moment electric tilting is stopped.

본 발명은 상용차량의 틸팅 안전회로에 관한 것으로써, 차량 캡(CAB) 틸팅시 안전사고를 방지하기 위한 상용차량의 틸팅 안전회로에 관한 것이다.The present invention relates to a tilting safety circuit of a commercial vehicle, and relates to a tilting safety circuit of a commercial vehicle for preventing a safety accident when tilting a vehicle cap (CAB).

일반적으로, 트럭과 같이 운전석을 이루는 캡(Cap)의 하부에 엔진과변속기 등이 구비된 경우에는, 이들 엔진과 변속기등의 정비를 위해 캡을 앞으로 젖혀 엔진과 변속기부위를 개방할 수 있는 틸팅장치가 장착되어지게 된다.In general, when an engine and a transmission are provided at a lower part of a cap forming a driver's seat, such as a truck, a tilting device capable of opening the engine and the transmission part by flipping the cap forward for maintenance of these engines and the transmission. Will be mounted.

상기한 틸팅장치는 수동과 전동 틸팅장치로 구성되어 있는데, 상기한 틸팅장치는 전동 틸트 모터, 틸트 스위치 틸트 부저, 마이크로 스위치와 릴레이를 포함하는 전장회로와 변속기의 기어 중립 스위치로 이루어져 있다.The tilting device includes a manual and an electric tilting device. The tilting device includes an electric tilt motor, a tilt switch tilt buzzer, an electric circuit including a micro switch and a relay, and a gear neutral switch of a transmission.

도 1은 종래의 틸팅 전장 회로를 도시한 예이다.1 shows an example of a conventional tilting electric circuit.

차량을 수리하기 위해 캡을 틸팅하는 순서로는 먼저, 운전자가 기어를 중립 위치에 위치시키면, 기어 중립 스위치가 '온' 상태를 유지한다. 이 후, 도 1에 도시되어 있는 틸팅 스위치(20)를 '온' 시키면, 변속기 인터 록 릴레이 스위치(30)가 접점 '온' 되면서, 틸트 파워 릴레이(40)가 여자되어 접점'온' 되어진다.In the order of tilting the cab to repair the vehicle, first, when the driver positions the gear in the neutral position, the gear neutral switch remains 'on'. Thereafter, when the tilting switch 20 shown in FIG. 1 is 'on', the transmission interlock relay switch 30 is 'on' the contact, and the tilt power relay 40 is excited to be 'on'. .

상기에서 틸트 파워 릴레이(40)가 여자되어 접점 '온' 됨에 따라, 틸트 릴레이(50)가 여자되어 접점 '온'되어 틸트 모터(60)에 전원을 공급하면, 상기 틸트 모터(60)가 구동되어 캡을 틸팅시킨다.As the tilt power relay 40 is excited and the contact 'on', as the tilt relay 50 is excited and the contact 'on' to supply power to the tilt motor 60, the tilt motor 60 is driven. To tilt the cap.

그러나, 상기한 회로구성은 캡 틸팅 중 변속기에 연결되어 있는 중립 스위치가 접점'온' 상태에서 '오프'상태가 되는 경우, 캡 틸팅이 정지하여 엔진 시동시 안전사고가 발생할 수 있는 문제점이 내포되어 있다.However, the above circuit configuration includes a problem that a safety accident may occur when starting the engine by stopping the cap tilting when the neutral switch connected to the transmission during the cap tilting becomes 'off' from the contact 'on' state. have.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로, 상용 차량의 수리를 위해 캡을 틸팅함에 있어서, 공압 주차 브레이킹 후 시동키를 온 조작한 상태에서 변속기 중립 스위치의 온/오프와 관계없이 차량의 캡이 틸팅될 수 있도록 하기 위한 상용차량용 틸팅 안전회로를 제공하기 위한 것이다.Accordingly, an object of the present invention is to solve the above problems, and in tilting the cap for repair of a commercial vehicle, irrespective of whether the transmission neutral switch is turned on or off in a state in which the ignition key is turned on and operated after pneumatic parking braking. It is to provide a tilting safety circuit for a commercial vehicle for allowing the cap of the vehicle to be tilted.

상기한 목적을 달성하기 위한 본 발명은,The present invention for achieving the above object,

상용차량의 캡을 틸팅하기 위해 사용자가 시동 키 조작하여 전원이 인가된 상태에서 주차 스위치, 틸팅 스위치 및 변속기 인터 록 스위치를 조작 '온'시키면 틸트 파워 릴레이가 여자되어 틸트 릴레이 부하 접점을 '온' 시켜 틸트 모터에 전원을 공급시켜 캡을 틸팅 시키는 상용차량의 틸팅 안전회로에 있어서,To tilt the cap of a commercial vehicle, when the user operates the start key and operates the parking switch, tilting switch and transmission interlock switch while the power is applied, the tilt power relay is excited to turn on the tilt relay load contact. In a tilting safety circuit of a commercial vehicle that supplies power to the tilt motor to tilt the cap,

상기 상용차량의 틸팅 안전회는 상시 전원과 기어 중립 스위치의 온/오프와 상관없이 캡을 틸팅시키고, 엔진 시동 중 공압 주차 브레이크가 해제되면 전원을 차단하여 전동 틸팅이 중단됨과 동시에 경고음을 발생시키는 것을 특징으로 한다.The tilting safety assembly of the commercial vehicle tilts the cap regardless of the on / off of the constant power supply and the gear neutral switch, and when the pneumatic parking brake is released during engine starting, shuts off the power to stop the electric tilting and generate a warning sound. It features.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 적용되는 상용차량의 틸팅 안전회로도 이다.2 is a tilting safety circuit diagram of a commercial vehicle applied to the present invention.

도 2에 도시되어 있는 바와 같이, 상용차량의 캡을 틸팅함에 있어서, 사용자가 시동 키 온 상태에서 주차 브레이크 스위치(100) 및 틸트 스위치(110), 변속기인터 록 스위치(115)를 접점 '온' 시키면, 틸트 파워 릴레이(130)가 여자되어 틸트 릴레이(140) 부하 접점이 '온' 된다.As shown in FIG. 2, in tilting the cap of a commercial vehicle, the user contacts the parking brake switch 100, the tilt switch 110, and the transmission interlock switch 115 in a state of starting key on. When the tilt power relay 130 is excited, the load relay of the tilt relay 140 is 'on'.

상기에서 틸트 릴레이(140) 부하 접점이 '온' 됨에 따라 틸트 모터(150)에 전원이 공급됨에 따라 상기 틸트 모터(150)가 구동되어 캡을 틸팅시킨다.As the tilt relay 140 load contact is turned on, the tilt motor 150 is driven as power is supplied to the tilt motor 150 to tilt the cap.

상기에서, 사용자가 주차 브레이크 스위치(100)를 접점 '온' 시킴에 따라 공압 주차 릴레이(101)가 여자되어 접점 스위치가 'D' 위치에서 'P' 위치로 전환되어 운전석 앞 클러스터 소정의 위치에 구비된 주차(P) 표시램프(210)가 점등된다.In the above, as the user 'turns on' the parking brake switch 100, the pneumatic parking relay 101 is excited to switch the contact switch from the 'D' position to the 'P' position to a predetermined position in front of the driver's seat. The parking (P) display lamp 210 is turned on.

하지만, 시동 키가 '온'된 상태에서 사용자의 오조작으로 주차 브레이크 스위치(100)를 '오프' 시키면, 공압 주차 릴레이(101)의 스위치가 'P' 위치에서 'D' 위치로 전환되어 경고 부저(200)에 전원을 인가하여 경고음을 발생시켜 사용자에게 경고함과 동시에 주차 인터 록 릴레이(130)가 '오프'되고, 그에 따라 틸트 릴레이(140)가 '오프' 됨에 따라 틸팅 모터(150)에 전원 공급이 차단되어 틸팅이 중단된다.However, if the parking brake switch 100 is 'off' by a user's misoperation while the ignition key is 'on', the switch of the pneumatic parking relay 101 is switched from the 'P' position to the 'D' position to warn. The power supply to the buzzer 200 generates a warning sound to warn the user and at the same time the parking interlock relay 130 is 'off', and thus the tilting motor 140 is 'off', thereby the tilting motor 150. The power supply is cut off and the tilting stops.

이로써, 상용차량의 캡의 틸팅시 안전사고를 방지할 수 있다.As a result, a safety accident can be prevented when the cap of the commercial vehicle is tilted.

이상 설명한 바와 같이 본 발명은 상용 차량의 수리를 위해 캡을 틸팅함에 있어서, 공압 주차 브레이킹 후 시동키를 온 조작한 상태에서 변속기 중립 스위치의 온/오프와 관계없이 차량의 캡이 틸팅될 수 있도록 함으로써, 엔진 시동 중 공압 브레이크가 해제되면 전원이 차단되어 틸팅이 이루어지지 않아 안전사고 발생을 방지할 수 있다.As described above, in the present invention, in the tilting of the cap for repair of a commercial vehicle, the cap of the vehicle can be tilted regardless of the on / off of the transmission neutral switch in the state in which the ignition key is operated after pneumatic parking braking. When the pneumatic brake is released during engine start, the power is cut off and tilting is prevented, thus preventing a safety accident.
