Abstract

The invention discloses a loader shoveling operation gear control method, device and system. The method comprises the steps: in the shoveling operation process of a loader, by obtaining the current speed of the loader, the gear state of a gearbox, the braking pressure, the angle of a bucket and an angle signal of a movable arm, judging whether the current braking pressure is greater than a pressure set value or not; judging whether the angle of the bucket and the angle of the movable arm are in a shoveling area or not; judging whether the current speed of the loader and the gear state of the gearbox are located in an optimal gear shifting interval or not; and according to the gear power information curve, obtaining the optimal gear shifting speed interval, pressing a KD key for 3s before the shoveling operation, then activating the system, when it is detected that the working state of the loader is at the optimal gear shifting operation point, increasing the rotating speed of an engine, and starting the gear shifting operation. The engine speed drop caused by load changes in the gear shifting process is prevented, the automatic KD function is realized in the shoveling operation process of the loader, the engine speed drop is prevented, the oil consumption is reduced, and the operation efficiency during shoveling is improved.

Description

technical field

[0001] The invention relates to the field of shift control of loaders, in particular to a gear control method, device and system for shovel loading operations of a loader. Background technique

[0002] The loader is mainly used for shoveling bulk materials such as soil, gravel, lime, coal, etc. When the loader is shoveling, when the driver drives the loader close to the material pile, the driver presses the KD key at this time, (KD key : Abbreviation of Kick Down key, when KD key is pressed, the vehicle can be lowered from 2nd gear to 1st gear); then the loader gear can be switched from 2nd gear to 1st gear, through this operation, a greater output torque to meet the high power demand of the loader during shoveling.

[0003] But at present, the time when the driver presses the KD key depends entirely on personal feeling, and the timing of carrying out the KD operation depends entirely on personal experience, and the speed of the vehicle is uncertain when the...
