본 고안은 조종편의성이 향상된 건설중장비의 킥다운 시스템에 관한 것으로서, 특히 작업상황에 따라 오른손 또는 왼손중 편리한 손으로써 용이하게 조작이 가능한 건설중장비의 킥다운 시스템에 관한 것이다.The present invention relates to a kickdown system of heavy construction equipment with improved maneuverability, and more particularly, to a kickdown system of heavy construction equipment that can be easily manipulated by a convenient hand in the right hand or the left hand according to the working situation.
종래의 기술에 의하면 건설 중장비의 구동중 가파른 언덕을 등판하는등 일시적으로 구동력이 부족하게 되는 상황에서는 트랜스밋션 콘토롤 제어에 설치된 킥다운 버튼을 눌러 변속레버의 위치를 2단에서 1단으로 신속하게 변환시키므로서 순간적으로 구동력을 높일 수 있도록 되어 있으나, 킥다운 버튼이 부착되는 트랜스 밋션 콘트롤 레버는 핸들의 좌측하방에 위치하므로 왼손만으로 조작가능하며, 킥다운버튼을 길게 돌출된 레버의 종단부에 부착되어 있으므로 조작이 매우 불편하여 실제적으로 신속한 조작이 필요한 상황에서 신속히 대응하지 못하는 문제점이 있었다.According to the related art, when the driving force is temporarily insufficient, such as climbing a steep hill while driving heavy construction equipment, the position of the shift lever is rapidly changed from 2 to 1 by pressing the kickdown button installed in the transmission control. It is possible to increase driving force instantly by converting, but the transmission control lever to which the kickdown button is attached is located on the lower left side of the handle and can be operated with only the left hand, and the kickdown button is attached to the end of the protruding lever. Since the operation is very inconvenient, there was a problem that can not respond quickly in a situation that requires a rapid operation.
본 고안은 이상과 같은 문제점을 해결하기 위해 안출된 것으로서, 순간적으로 구동력이 부족하게 되는 상황에서 신속하게 킥다운 버튼을 조작할 수 있도록 운전자 오른쪽에 위치하는 죠이스틱에 제2의 킥다운버튼을 설치하여 작업상황에 따라 오른손 또는 왼손중 편리한 손으로 신속히 조작할 수 있도록 하여 실제조작시 신속하게 대응하도록 하는데에 그 목적이 있는 것이다.The present invention was devised to solve the above problems, and by installing a second kickdown button on the joystick located on the right side of the driver so that the user can quickly operate the kickdown button in a situation where the driving force is momentarily insufficient. Its purpose is to be able to quickly operate with either the right hand or the left hand according to the working situation so as to respond quickly in actual operation.
첨부도면에 의해 본 고안의 내용을 설명하면 다음과 같다.Referring to the contents of the present invention by the accompanying drawings as follows.
제1도 및 제2도에 도시된 바와 같이 트랜스 밋션 콘트롤레버(9)와 죠이스틱레버(10) 선단에 각각 킥다운 버튼(1. 2)을 부착 구비시키고, 상기한 킥다운 버튼(1. 2)이 눌러진 상태에서 제어신호를 발생시키는 제어기(3)와, 상기 제어신호에 의해 동작하는 킥다운 솔레노이드밸브(4a)와, 상기 밸브(4a)로 부터 유입된 압유에 의해 동작하는 방향제어밸브(7)와, 상기 방향제어밸브(7)로 부터 유입된 압유에 의해 동작하는 1단 클러치(5a)로 구성된다.As shown in Figs. 1 and 2, a kickdown button (1.2) is attached to the front of the transmission control lever (9) and the joystick lever (10), respectively. Controller 3 for generating a control signal in a pressed state, a kick-down solenoid valve 4a operated by the control signal, and a directional control valve operated by pressure oil flowing from the valve 4a. (7) and a first stage clutch (5a) operated by pressure oil introduced from the directional control valve (7).
이상과 같이 구성되는 본 고안의 작용은 다음과 같다.The operation of the present invention configured as described above is as follows.
중장비가 2단으로 주행중에는 2단 솔레노이드밸브(46)가 동작된 상태로 상기 솔레노이드밸브(26)를 통해 유입된 압유에 의해 2단 방향제어밸브(6)가 동작하게 되고, 이에따라 유입된 압유는 킥다운 방향제어밸브(7)를 통해 2단 클러치(5b)에로 유입된 상태가 되어 계속 2단이 유지되는데, 이때 작업자에 의해 트랜스 밋션 콘트롤레버(9) 또는 죠이스틱레버(10) 선단에 부착된 킥다운 버튼(1. 2)이 눌려지면 제어기(3)에 의해 킥다운 솔레노이즈밸브(4a)의 솔레노이드가 통전되어 동작하게 되고, 이에 따라 상기 솔레노이드밸브(4a)를 통해 유입된 압유는 킥다운 방향 제어밸브(7)를 동작시켜서, 2단방향 제어밸브(6)를 통해 유입된 압유의 유로를 1단 클러치(5a)쪽으로 변경시키므로 순간적으로 2단에서 1단으로 킥다운되는 것이다.While the heavy equipment is traveling in two stages, the two-stage directional control valve 6 is operated by the hydraulic oil introduced through the solenoid valve 26 while the two-stage solenoid valve 46 is operated. Through the kick-down direction control valve (7) to enter the second stage clutch (5b) is maintained in the second stage, which is attached to the end of the transmission control lever (9) or joystick lever (10) by the operator When the kick-down button 1.2 is pressed, the solenoid of the kick-down solenoid valve 4a is energized and operated by the controller 3, whereby the pressure oil introduced through the solenoid valve 4a is kicked down. By operating the directional control valve (7), the flow path of the hydraulic oil flowing through the two-stage direction control valve (6) toward the first stage clutch (5a) is instantaneously kicked down from the second stage to the first stage.
상술한 바와 같은 본 고안에서는 신속하게 킥다운 조작할 수 있도록 킥다운버튼( 2)을 운전석 오른쪽에 위치하는 죠이스틱(10) 선단부에도 설치하였으므로 실제적으로 작업자의 대다수가 오른손잡이임을 감안한다면 작업성이 매우 편리해졌을 뿐만 아니라, 종전과 같이 트랜스밋션 제어레버(9)에도 킥다운버튼(1)이 설치되어 있으므로 작업자가 작업상황에 따라 오른손 또는 왼손중 편리한 손으로 신속히 조작할 수 있도록 하여 순작적으로 구동력 증가가 요구되는 실제적인 상황에 신속히 대처할 수 있도록 한 유용한 고안이다.In the present invention as described above, the kickdown button (2) is also installed at the tip of the joystick (10) located on the right side of the driver's seat for quick kick-down operation. Not only is it convenient, but also the transmission control lever 9 is equipped with a kick-down button 1 so that the operator can quickly operate with either the right hand or the left hand according to the working situation, thereby increasing the driving force. It is a useful design that allows you to respond quickly to the actual situation in which it is required.
