Abstract
An automatic control method for speed-varying box of bulldozer features that a programmable electronic controller with input connected to a rotation speed sensor is installed to the speed-varying box. The rotation speed of the input axle of hydraulic torque converter is sampled. After analysis and comparision of electronic controller, the signal is sent to the gear-shifting control mechanism of speed-varying box, so realizing automatic gear shift. Its advantages are high engine efficieny and saving labour.
Description
The present invention relates to a kind of autocontrol method that is used for speed-varying box of bulldozer.
Existing speed-varying box of bulldozer is shifted, all is manually-operated.In the bulldozer running, meet obstructions when needing to slow down, require operating personnel to maintain sharp vigilance, according to feeling in time shifted, to keep operate as normal.This operation, mechanical efficiency is low, and labour intensity is big, makes operating personnel's fatigue easily.
Purpose of the present invention is to provide a kind of by programmable electronic control system, realizes bulldozer fluid drive, reaches a kind of autocontrol method for speed-varying box of bulldozer of the permanent power running of motor.
Below in conjunction with drawings and Examples, introduce technical scheme of the present invention.
Fig. 1 is the schematic diagram of apparatus of the present invention.
With reference to accompanying drawing, on the gearbox 1 of bulldozer, a programmable electronic controller 4 is installed, the electronic controller input connects speed probe 3, fluid torque-converter 2 power shafts to gearbox 1 carry out the tach signal sampling, after electronic controller 4 is analyzed relatively, signal is delivered to the shift control mechanism 5 of gearbox, realize fluid drive speed change to bulldozer.
The present invention to the relation between torque-converters input speed and the gearbox output speed, analyzes comparison by electronic control system, by electronic control system trasmission shifting system is controlled, and reaches automatic change bulldozer travel speed.Improve bulldozer motor service efficiency, alleviated labor intensity of operating personnel.
Claims (1)
1, a kind of autocontrol method of speed-varying box of bulldozer, it is characterized in that: on the gearbox (1) of bulldozer, a programmable electronic controller (4) is installed, the electronic controller input connects speed probe (3), fluid torque-converter (2) power shaft to gearbox (1) carries out the tach signal sampling, after electronic controller (4) is analyzed relatively, signal is delivered to the shift control mechanism (5) of gearbox, realize fluid drive speed change to bulldozer.
