Embodiment 1

[0049] Embodiment 1: the condition parameter selects the turbine speed as an example;

[0050] A flowchart of an embodiment of the present invention is as follows figure 2 shown, the specific steps are as follows:

[0051] (1) Manually adjust the quick oil filling time of the clutch on the gearbox test bench to make the clutch combine smoothly, and use this time as the theoretical oil filling time T of the clutch CK ;

[0052] (2) According to the theoretical oil filling time T CK The clutch is filled with oil as the benchmark, and the oil filling curve selects the first two stages in the clutch engagement process, such as image 3 shown. Acquisition pressure curve start time t s and the end time t e Corresponding turbine speed, get the reference turbine speed difference N CK_Basic , to form the reference turbine speed difference strategy table and store it in the transmission control unit;

[0053] (3) When the state of the whole machine satisfies the self-calibratio...

Embodiment 2

[0058] A self-calibration system under the condition of a construction machinery gearbox, comprising a controller, the controller comprising a memory and a processor, the memory is used to store instructions, and the instructions are used to control the processor to operate to execute the above The self-calibration method under the condition of the complete construction machinery gearbox.

[0059] In some embodiments, the memory also stores the reference condition parameter difference.

[0060] In some embodiments, the self-calibration system under the condition of the construction machinery gearbox further includes: a shift handle, a parking brake, a transmission control unit, an engine control unit, a temperature sensor, a rotational speed sensor, and a self-calibration control unit ;Shift handle, parking brake, transmission control unit, engine control unit, temperature sensor, speed sensor, self-calibration control unit are all connected to the controller,

[0061] The sh...

Abstract

The invention discloses a self-calibration method and system under the condition of a complete construction machinery gearbox. Through the method, the quick oil filling time of the gearbox clutch can be automatically calibrated, so as to make the clutch combination more stable, reduce the gear shift impact of the gearbox, and help the It is used for batch installation of gearboxes. The self-calibration method of the present invention can accurately obtain the quick oil filling time of each clutch, can compensate for the inconsistency of the production of gearbox components, and at the same time ensure that the gearbox still maintains good shifting smoothness after long-term use or transmission oil replacement.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and relates to a method and system for self-calibration of a gearbox, in particular to a method and system for self-calibration of a gearbox of a construction machinery under the condition of a complete machine. Background technique [0002] The construction machinery power shift automatic transmission contains multiple wet clutches, and different transmission gears are formed according to the combination of different clutches. The wet clutch consists of clutch pack, piston, spring, array of friction plates and light plates. When the clutch is engaged, the transmission oil enters and gradually fills the clutch pack, and then the oil pushes the piston to overcome the spring force to eliminate the idle travel between the piston and the friction plate. As the oil pressure increases, the clutch is gradually compressed, and the transmittable torque Gradually increase and reach the set ...
