Output controlling device for earth moving machine
专利汇可以提供Output controlling device for earth moving machine专利检索，专利查询，专利分析的服务。并且PURPOSE: To make machine operable with the maximum working capacity by automatically switching over set up speeds according to the manipulated variable of a lever.
CONSTITUTION: Functions A
1 WA
5 from a function generator 6 are inputted to a function selector 7, and functions corresponding to velocity stages detected with a velocity stage detector 4 are selectively outputted. Speed V
s corresponding to manipulated variable 4 detected by means of a throttle lever manipulated variable detector 2 is read out from the selected functions by means of a coefficient generator 8, and is added to a subtracter 9 as a set up value of speed. Detected value of speed V
f is further inputted to the subtracter 9, and deviation between both the values Δe is found. Controlling operation unit 11 outputs voltage according to inputted deviation voltage Δe, and switches over a solenoid valve 13 through a drive unit 12. Load on a blade 15 is thereby controlled so as to equalize both the detected and the set up speed V
f and V
s . In this way, the earth moving machine can be operated bringing maximum working capacity forth.
