Description

유압식 조향장치가 적용된 캐빈형 농작업차Cabin Farming Vehicle with Hydraulic Steering System
본 발명은 농작업차에 관한 것으로, 상세하게는 운전석이 캐빈(cabin)에 의해 보호되고 차륜 조향을 위하여 유압식 조향장치가 적용된 캐빈형 농작업차에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a farm vehicle, and more particularly, to a cabin type farm vehicle in which a driver's seat is protected by a cabin and a hydraulic steering device is applied for wheel steering.
농작업차 예컨대, 트랙터가 점차 대형화되고 고사양화 되는 추세에서, 외부 환경으로부터 운전석을 보호하고 정숙성을 향상시켜 보다 쾌적하고 안전한 환경에서 기체 조작이 행해질 수 있도록, 최근 투명한 유리로 된 박스 형태의 캐빈(cabin)을 통해 운전석을 보호하는 구조를 널리 채택하는 추세에 있다. 이를 통상적으로 '캐빈형 농작업차'라 한다. As farm trucks, such as tractors, have become increasingly large and high-specified, recently transparent glass box-type cabins to protect the driver's cab from the outside environment and improve quietness so that gas can be operated in a more comfortable and safe environment. ) Is widely adopted to protect the driver's seat. This is commonly referred to as a 'cabin farm vehicle'.
또한, 농작업차가 대형화되고 고사양화되는 추세에서 운전자 힘에 의존하는 기계식 조향장치를 채택하던 종래와는 달리, 유압을 이용하여 핸들(스티어링 휠)의 조작감을 가볍게 하고, 따라서 안정된 조향 성능 및 빠른 조향 응답성이 발휘될 수 있도록 유압식 조향장치를 보편적으로 설치하는 추세에 있다.In addition, unlike the prior art, which adopts a mechanical steering device that relies on driver's power in the trend of a large and high specification farm truck, it makes use of hydraulic pressure to lighten the operation feeling of the steering wheel (steering wheel), thus providing stable steering performance and fast steering response. There is a tendency to install hydraulic steering system universally so that sex can be exerted.
도 1은 유압식 조향장치를 탑재한 종래 캐빈형 농작업차에 대한 개략 구성도로서, 오일이 임시 저장되는 오일 저장부(100)와 이에 임시 저장된 오일을 압축시키는 유압펌프(120)가 엔진 룸 적소에 배치되고, 유압에 의해 작동하는 조향실린더(200)가 차체 전방 하부의 조향륜(W)에 근접하여 차축에 평행하게 배치된다.1 is a schematic configuration diagram of a conventional cabin-type farm truck equipped with a hydraulic steering device, an oil storage unit 100 in which oil is temporarily stored and a hydraulic pump 120 for compressing the oil temporarily stored therein are located in an engine room. The steering cylinder 200, which is disposed at and operated by hydraulic pressure, is disposed in parallel to the axle in proximity to the steering wheel W in the lower portion of the vehicle front.
조향실린더(200)는 운전석 전면부에 위치하는 파워스티어링유닛(220)에 의하여 흐름방향이 제어된 유압에 의해 작동하여 조향륜(전륜)을 작동시키고, 파워스티어링유닛(220)은 스티어링컬럼유닛(240)을 매개로 하여 운전석 전면부 공간 상으로 위치하는 조향 핸들(스티어링 휠, 260)에 연동 가능하게 연결된다.The steering cylinder 200 is operated by hydraulic pressure controlled in the flow direction by the power steering unit 220 located in the front of the driver's seat to operate the steering wheel (front wheel), the power steering unit 220 is a steering column unit ( It is connected to the steering wheel (steering wheel, 260) located on the driver's front space through the 240.
조향실린더(200)에는 좌, 우로 구분되는 두 개의 실린더 공간이 있으며, 조향 핸들(260) 조작으로 파워스티어링유닛(220)에 의하여 방향 제어된 작동유체가 두 개의 실린더 공간 중 어느 한 실린더 공간으로 공급되면, 두 실린더 공간 사이의 압력차로 조향실린더(200) 내에 위치한 피스톤 로드(도면부호 생략)가 수평 이동함으로써 조향륜을 변위시키게 된다. The steering cylinder 200 has two cylinder spaces, which are divided into left and right sides, and the operating fluid controlled by the power steering unit 220 by the steering handle 260 is supplied to one of the two cylinder spaces. As a result, the piston rod (not shown) located in the steering cylinder 200 moves horizontally with the pressure difference between the two cylinder spaces to displace the steering wheel.
조향이 행해지는 동안 조향실린더(200)에는 작동유체가 지속적으로 공급되고 일을 한다. 그러나 핸들을 끝까지 돌려 그 상태를 유지시키는 U턴 작업과 같이, 조향실린더(200) 한쪽으로 작동유체 공급은 계속되지만 더 이상 유체가 일을 하는 데에 에너지를 소비하지 못한다면 유압계통 전반에 걸쳐 압력이 과도하게 상승될 우려가 있다. While steering is performed, the steering cylinder 200 is continuously supplied with working fluid. However, if the working fluid continues to be supplied to one side of the steering cylinder 200 but no longer consumes energy to work, such as a U-turn operation that rotates the handle all the way, the pressure across the hydraulic system There is a risk of excessive rise.
따라서 U턴과 같은 조향 조작 시 유압계통 전반에 걸친 안정된 압력의 유지를 위하여 통상의 릴리프밸브(도시 생략)를 채택하고 있으며, 이에 따라 조향실린더(200)로 작동유체가 더 이상 공급되기 어려운 U턴과 같은 상황에서 파워스티어링유닛(22)으로 공급된 작동유체는 상기 릴리프밸브를 통해 다시 오일 저장부(100)로 되돌려지게 된다.Therefore, in order to maintain a stable pressure throughout the hydraulic system during the steering operation such as the U-turn, a conventional relief valve (not shown) is adopted. Accordingly, the U-turn, which is difficult to supply the working fluid to the steering cylinder 200 anymore, is adopted. In such a situation, the working fluid supplied to the power steering unit 22 is returned to the oil storage unit 100 again through the relief valve.
릴리프밸브의 적용에 있어 종래에는, 부품의 모듈화를 통한 장치 소형화 및 공간의 유효한 활용의 도모를 위하여 상기 파워스티어링유닛(220)에 릴리프밸브를 일체형으로 구성하고 있다. 그러나 릴리프밸브는 알려진 바와 같이, 유속 및 압력변화에 따라 작동 중 불규칙한 소음 및 진동이 발생하는 문제를 안고 있다.In the application of the relief valve, the relief valve is integrally formed in the power steering unit 220 in order to reduce the size of the device and effectively utilize the space through modularization of components. However, the relief valve, as is known, has a problem that irregular noise and vibration occurs during operation in accordance with the flow rate and pressure changes.
따라서 운전석 전면부 조향핸들(260)에 근접하여 파워스티어링유닛(220)을 배치한 도 1과 같은 종래 캐빈형 농작업차의 경우, 조향을 위해 핸들을 돌릴 경우 릴리프밸브에 의한 불쾌한 소음과 진동이 운전자게 고스란히 전달되고, 캐빈으로 공간이 밀폐되어 있기 때문에 해당 소음이 상대적으로 더욱 크게 운전자에게 전달되는 문제가 있다.Therefore, in the case of the conventional cabin-type agricultural work vehicle as shown in FIG. 1 in which the power steering unit 220 is disposed close to the driver's front steering wheel 260, when the steering wheel is turned for steering, unpleasant noise and vibration caused by the relief valve are prevented. Since the vehicle is completely transmitted to the driver and the space is enclosed by the cabin, the corresponding noise is relatively larger than the driver.
본 발명이 해결하려는 기술적 과제는, 운전석이 캐빈(cabin)에 의해 보호되고 유압식 조향장치를 탑재하는 캐빈형 농작업차 조향 시 파워스티어링유닛이 작동할 때 발생되는 유동 소음과 진동의 효과적 저감을 도모하고, 이에 따라 조용하고 안락한 승차감을 제공할 수 있는 캐빈형 농작업차를 구현하고자 하는 것이다.The technical problem to be solved by the present invention is to effectively reduce the flow noise and vibration generated when the power steering unit is operated when the cabin is protected by a cabin (cabin), the steering of the cabin-type farm truck equipped with a hydraulic steering device. And, accordingly, to implement a cabin-type farm work vehicle that can provide a quiet and comfortable ride.

Therefore, it is possible to provide a farming vehicle with improved driver's quietness.
또한, 농작업차를 구성하는 요소 중에서 상당히 견고한 중량체인 미션케이스에 파워스티어링유닛 취부를 위한 취부대와 탄성받침대가 설치됨에 따라, 유체 맥동에 의한 파워스티어링유닛 자체 진동과 스티어링컬럼유닛을 통해 조향 중 운전자에게 전달되는 진동 및 진동에 의해 유발되는 소음을 억제시킬 수 있다.
