Engine load control device of work vehicle |
摘要 |
In an engine load control device of a work vehicle, an output of an engine is transmitted to a hydraulic actuator via a variable displacement type hydraulic pump. A controller is configured to calculate, based on a target rotational speed of the engine detected by a target rotational speed detecting portion and an actual rotational speed of the engine detected by an actual rotational speed detecting portion, a variation rate per unit time of a difference between the detected results, and to adjust the maximum absorbing torque of the hydraulic pump according to the magnitude of the variation rate. |
