Locking and unlocking method and locking and unlocking system for locking type hydraulic torque converter of bulldozer
The invention discloses a locking and unlocking method and a locking and unlocking system for a locking type hydraulic torque converter of a bulldozer. The locking type hydraulic torque converter is used for transferring power of an engine of the bulldozer to a gearbox. The method comprises the steps that target rotating speeds of a locking turbine at different throttle openings and in different working states of the locking type hydraulic torque converter are calculated; control parameters are acquired; and locking and unlocking control is carried out on the locking type hydraulic torque converter according to the control parameters and the target rotating speeds of the locking turbine, wherein the different working states comprise a coupling working condition, a peak efficiency working condition and a high efficiency area working condition, the control parameters comprise bulldozer brake information, gear information, the throttle openings, rotating speeds of the turbine, and water temperature values of the engine, and the gear information comprise shifting information and neutral gear information. The system comprises a locking and unlocking control trigger submodule and a locking and unlocking judgment submodule. The locking and unlocking method and the locking and unlocking system provides multiple parameters for the locking and unlocking control, so that different locking and unlocking requirements of the bulldozer on the various working conditions can be met.
