CAPACITY CONTROLLING METHOD OF HYDRAULIC PUMP FOR WORKING MACHINE OF WORKING VEHICLE AND CAPACITY CONTROLLING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a capacity controlling method of a hydraulic pump for a working machine of a working vehicle having a small sense of incompatibility of an operator for the operation of the working machine as well as the small deceleration shock even in the case of rising of a bucket and a capacity controlling device.;SOLUTION: In the capacity controlling device of the hydraulic pump for the working machine of the working vehicle having the working machine mounting the bucket on the front end section of a lift arm capable of being freely undulated, it is equipped with a pump controller controlling the capacity of the hydraulic pump for the working machine driving the working machine, a capacity alternative device altering the capacity of the hydraulic pump for the working machine based on an instruction of the pump controller, a lift angle detector detecting an angle to the ground surface of the lift arm and a load detector detecting whether or not the bucket is in a load state, and when the bucket in a load state goes across a predetermined height in the case of rising, the pump controller makes the control gradually reduce the capacity of the hydraulic pump for the working machine based on output of the lift angle detector and the load detector.;COPYRIGHT: (C)2006,JPO&NCIPI
