본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명 실시예로서 적용되는 굴삭기의 개략적인 부분 유압회로도이고,1 is a schematic partial hydraulic circuit diagram of an excavator applied as an embodiment of the present invention,

제2도는 본 발명 실시예에 따른 제어유통도.2 is a control flow chart according to an embodiment of the present invention.

제3도는 부하에 대한 주행속도의 특성곡선도이다.3 is a characteristic curve diagram of the traveling speed with respect to the load.

Claims (3)

주행모우터(6, 8)의 조작페달(15)의 조작량(θi)에 부합하는 전류신호를 입력받아 조작량 (θi)가 제로가 아닐 경우에, 조작량 (θi)에 따른 전자비례밸브(10)의 제어전류치(Ia) 및 제1, 2펌프(3, 4)용 사판각조절밸브(3b, 4b)의 제어전류전류치(Ib)를 연산하여 출력하는 한편, 상기 조작량(θi)이 최대(θmax)일 경우에 있어서 주행모우터(6, 8)의 작동속도 감지센서(14)로 부터 작동속도(Vi)에 부합하는 전류신호를 입력받고, 이 입력된 작동속도(Vi)를 제3펌프(5)와 주행모우터(6, 8)용 사판각조절기구(6a, 8a)사이에 유로를 선택적으로 개폐시켜주기 위해 설치되는 솔레노이밸브(11)의 전류인가여부에 따라 절환속도(V1)또는 허용최저속도(V2)와 비교하여, 상기 밸브(11)로 인가되는 전류를 차단시키거나, 출력시켜 상기 주행모우터(6, 8)의 사판각을 조절해주도록 된 중장비 최적 주행제어방법.Electronic proportional valve according to the operation amount θ i when a current signal corresponding to the operation amount θ i of the operation pedal 15 of the traveling motors 6 and 8 is input and the operation amount θ i is not zero. The control current value Ia of (10) and the control current value Ib of the swash plate angle control valves 3b and 4b for the first and second pumps 3 and 4 are calculated and output, while the operation amount θ i is calculated. In the case where the maximum is θmax, a current signal corresponding to the operating speed V i is received from the operating speed sensor 14 of the driving motors 6 and 8, and the input operating speed V i is received. ) Is applied to the solenoid valve 11 provided to selectively open and close the flow path between the third pump 5 and the swash plate angle adjustment mechanisms 6a and 8a for the driving motors 6 and 8. Accordingly, the swash plate angles of the traveling motors 6 and 8 are adjusted by cutting off or outputting the current applied to the valve 11 in comparison with the switching speed V 1 or the allowable minimum speed V 2 . To give Non-optimal drive control method. 제1항에 있어서, 상기 절환속도(V1)이 상기 솔레노이드밸브(11)에 전류가 인가되지 않은 경우의 주행최대속도(V1max)의 90%로 된 것을 특징으로 하는 중장비 최적주행 제어방법.The method of claim 1, wherein the switching speed (V 1 ) is 90% of the maximum traveling speed (V 1 max) when no current is applied to the solenoid valve (11). . 제1항에 있어서, 상기 허용최저속도(V2)가 상기 솔레노이드 밸브(11)에 전류가 인가된 경우에 상기 제1, 2펌프(3, 4)의 컷오프(cut-off)속도(Va)의 110%로 된 것을 특징으로 하는 중장비 최적주행 제어방법.The method of claim 1, wherein the allowed minimum speed (V 2) is cut-off (cut-off) the speed of the first and second pumps (3, 4) when the current to the solenoid valve 11 is applied (V a Optimal driving control method for heavy equipment, characterized in that 110% of). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
