Abstract
PURPOSE: To simplify the operation of speed-changing by using the pressure oil in a closed circuit to control a variable oil pressure pump at a neutral position when a change lever of a transmission is operated for synchronizing the rotation of a variable oil pressure pump with the rotation on the wheel side easily.
CONSTITUTION: For mixing concrete materials in a drum 10 of a concrete mixer truck, the power of an engine 1 is transmitted to a variable oil pressure pump 14 via a power take-off 6 and a shaft 7. When a control lever 17 is turned to a position shown by a solid line, the pump 14 is brought to a position of regular rotation, and the pressure oil is supplied to an oil motor 16 through a high pressure flow-line 11 by the pump 14 for rotating the drum 10 regularly. Then, when a transmission 3 is given a speed-changing operation during the regular rotation of the drum 10, a switch 30 is operated by the stepping-on of a clutch pedal 29 to switch over a switch valve 28, and the pressure oil in the flow-line 11 is supplied into an oil chamber 24 of a cylinder 21 via a valve 28 for controlling the pump 14 at a neutral position.
