Document Type and Number:
Japanese Patent JP2007506916
Kind Code:
A
Abstract:
The invention relates to a control and adjustment system for a lifting mechanism ( 100 ) of a loading blade ( 6 ) in a mobile machine tool. Said lifting mechanism is made up of at least one first and second blade cylinder ( 1, 2 ), at least one first and second lifting cylinder ( 61, 62 ) and one first and second hydropump ( 15, 75 ) which can be adjusted with regard to the pump volume. The adjusting pistons ( 3, 5 ) which can be displaced in the first and second blade cylinders ( 1, 2 ), respectively, separate both blade cylinders ( 1, 2 ) into two adjusting pressure chambers ( 7 and 8, 9 and 10 ). The adjusting pistons ( 63, 65 ) which can be displaced in the two lifting cylinders ( 61, 62 ) respectively separate the two lifting cylinders ( 61, 62 ) into the two adjusting pressure chambers ( 67 and 68, 69 and 70 ) in an analogous manner. In a first closed hydraulic circuit, a first and the second connection ( 14, 17 ) of the first hydropump ( 15 ) is, respectively made to the piston side of the piston pressure chamber ( 7, 9 ) of one blade cylinder ( 1, 2 ) and to the piston rod side of the adjusting pressure chamber ( 10, 8 ) of the other blade cylinder ( 2, 1 ). The first and second connection ( 74, 77 ) of the second hydropump ( 75 ) is respectively made in a second closed hydraulic circuit to a piston side adjusting pressure chamber ( 70, 67 ) of a lifting cylinder ( 62, 61 ) and to the piston rod side of the adjusting pressure chamber ( 68, 69 ) of the other lifting cylinder ( 61, 62 ).
