본 발명은 차량의 방향전환을 위하여 설치되는 조향장치를 수동조작은 물론, 필요에 따라 또는, 유사시 자동조작 상태로 전환하여 안정된 조향이 이루어질 수 있도록 한 차량용 조향장치에 관한 것이다.The present invention relates to a vehicle steering apparatus which enables a stable steering by switching the steering apparatus installed for changing the direction of the vehicle, as well as manual operation as needed or in case of emergency.
종래의 조향장치는 도1에서와 같이 유압펌프(301)와 로터리 밸브, 유압 실린더(201)가 조향수단인 핸들(101)에 연결 설치되어 있으며, 상기 유압펌프에서 토출된 유압이 로터리 밸브로 전달되고 이 상태에서 운전자가 핸들을 조작하게 되면 상기 로터리 밸브에서의 유압이 유압실린더를 작동시키게 되며 이 유압실린더의 작동에 따라 조향기구가 작동하여 차량의 조향이 이루어지도록 구성되어 있었다.In the conventional steering apparatus, as shown in FIG. 1, the hydraulic pump 301, the rotary valve, and the hydraulic cylinder 201 are connected to the handle 101 which is a steering means, and the hydraulic pressure discharged from the hydraulic pump is transferred to the rotary valve. In this state, when the driver operates the steering wheel, the hydraulic pressure in the rotary valve operates the hydraulic cylinder, and the steering mechanism is operated to operate the vehicle according to the operation of the hydraulic cylinder.
그러나, 상기와 같은 종래의 조향장치는, 차량의 운행도중 운전자의 핸들 조작에 따라 상기 유압시스템이 작동되고 이 유압시스템의 작용으로 상기 운행중인 차량의 조향이 이루어지도록 되어 있었기 때문에 상기 핸들에 이상이 발생할 경우에는 상기 조향이 이루어지지 못하여 사고를 유발하게 되는 폐단이 있었으며, 또 상기 핸들의 조작을 일일이 수동조작에 의존해야 하므로써 운전자의 피로도가 가중되는 점 등의 문제점이 있었다.However, the conventional steering apparatus as described above has an abnormality in the steering wheel because the hydraulic system is operated according to the steering wheel operation of the driver while the vehicle is in operation, and the steering of the vehicle in operation is made by the operation of the hydraulic system. In case of occurrence, there was a problem that the steering could not be made and caused an accident, and there was a problem that the fatigue of the driver was increased by having to rely on manual operation of the steering wheel.
본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로, 차량의 방향전환을 위하여 설치되는 조향장치를 수동조작과 병행하여 자동적으로 조작할 수 있도록 하고 상기 자동조작에 의하여 차량의 안전운행과 운전자의 피로도를 크게 저감시킬 수 있는 차량용 조향장치를 제공하려는 것인바, 이를 이하에서 첨부한 도면과 실시예에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned problems in the related art, and it is possible to automatically operate in parallel with manual operation a steering apparatus installed for changing the direction of the vehicle, and the safe operation and It is to provide a vehicle steering apparatus that can significantly reduce the fatigue of the driver, which will be described in detail based on the accompanying drawings and embodiments below.
핸들(1)과 연결되는 유압실린더(2)에 조향을 위하여 사용되는 유압펌프(3)를 연결하고 이들에 의하여 차량을 조향하도록 한 것에 있어서, 상기 유압실린더(2)와 유압펌프(3)들 사이에 수동 및 자동조향을 제어하는 제어밸브(4)를 설치하고 이 제어밸브(4)에는 도로의 상태를 감지하는 센서(6)가 연결되는 제어부(5)를 연결, 설치하고 상기 핸들(1)에는 이의 이상상태를 감지하는 센서(7)를 설치하며 이 센서(7)는 상기 제어부(5)에 연결하도록 설치하여 구성된 것이다.In connecting the hydraulic pump 3 used for steering to the hydraulic cylinder 2 connected to the handle 1 and steering the vehicle by them, the hydraulic cylinder 2 and the hydraulic pumps 3 are provided. A control valve 4 for controlling manual and automatic steering is installed therebetween, and the control valve 4 connects and installs a control unit 5 to which a sensor 6 for detecting a state of a road is connected. ) Is provided with a sensor (7) for detecting the abnormal state and the sensor (7) is installed and configured to connect to the control unit (5).
이상과 같이 구성된 본 발명의 실시예는, 평상시 차량을 운행하면서 조향을 하게 되면, 상기 유압펌프(3)로부터 유압이 발생되어 제어밸브(4)의 수동라인을 따라 유압이 유압실린더(2)에 공급하게 되고 이 수동라인의 유압공급은 상기 제어밸브(4)에 연결된 제어부(5)에 의하여 콘트롤되며 이 상태에서 핸들(1)의 조작에 의한 수동조향이 이루어지게 된다.According to the embodiment of the present invention configured as described above, when steering is carried out while driving a vehicle normally, hydraulic pressure is generated from the hydraulic pump 3 so that hydraulic pressure is applied to the hydraulic cylinder 2 along the manual line of the control valve 4. The hydraulic supply of the manual line is controlled by the control unit 5 connected to the control valve 4, and in this state, manual steering is performed by operating the handle 1.
상기와 같이하여 수동조작에 의한 차량의 운행도중 핸들(1) 등에 이상이 발생하게 되면, 이를 센서(7)가 감지하여 즉시 제어부(5)에 이상상태를 인가하게 되며 센서(7)로부터 이상신호를 받은 제어부(5)는 즉시 제어밸브(4)를 자동라인으로 전환시키게 되고, 이와 동시에 센서(6)는 노면이나 도로의 상태를 감지하여 상기 제어부(5)로 전달하게 된다.As described above, when an abnormality occurs in the steering wheel 1 or the like during the operation of the vehicle by manual operation, the sensor 7 detects this and immediately applies an abnormal state to the controller 5, and the abnormal signal from the sensor 7. Receiving the control unit 5 immediately switches the control valve 4 to the automatic line, and at the same time the sensor 6 detects the state of the road surface or the road will be delivered to the control unit (5).
상기와 같이하여 제어부(5)에 센서(6)(7)들로부터의 신호가 입력되면, 이 제어부(5)는 상기 센서(6)로부터 입력된 도로의 상황에 따라 조향각을 결정하고 이를 센서(7)에 전달하게 되며 상기 결정된 조향각에 따라 센서(7)가 유압실린더(2)를 작동시켜 자동조향이 이루어지게 된다.When the signals from the sensors 6 and 7 are input to the controller 5 as described above, the controller 5 determines the steering angle according to the situation of the road input from the sensor 6, and determines the sensor ( 7) and the sensor 7 operates the hydraulic cylinder 2 in accordance with the determined steering angle, thereby automatically steering.
또, 상기의 자동조향은 핸들(1)의 이상발생시 뿐만아니라, 운전자가 자의적으로 상기 제어부(5)를 자동조향 상태로 전환하게 되면, 상기 동일한 작동에 의하여 차량의 조향을 자동적으로 할 수 있게 되는 것이다.In addition, the automatic steering is possible not only at the time of abnormality of the steering wheel 1, but also when the driver arbitrarily switches the control unit 5 to the automatic steering state, the vehicle can be automatically steered by the same operation. will be.
이상과 같은 본 발명은, 차량의 방향전환을 위하여 설치되는 조향장치를 수동조작과 병행하여 자동적으로 조작할 수 있도록 하고 상기 핸들의 이상이 발생할 때, 즉시 자동조향으로 전환되도록 하며 이 자동조작에 의하여 차량의 안전운행을 도모할 수 있고 또 운전자가 자의적으로 자동조향으로 콘트로 할 경우, 운전자의 핸들 조작없이도 차량의 조향이 자동적으로 이루어질 수 있으며 이에따라 운전자의 피로도를 크게 줄일 수 있게 되는 점 등의 특징을 지닌 것이다.The present invention as described above, the steering device installed to change the direction of the vehicle can be automatically operated in parallel with the manual operation and when the abnormality of the steering wheel occurs, it is immediately switched to the automatic steering and by this automatic operation If the driver can drive the vehicle safely and control the driver with automatic steering, the steering of the vehicle can be done automatically without the driver's steering wheel, and the driver's fatigue can be greatly reduced. Will have.
