[0029] The principles and features of the present invention will be described below. The examples cited are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] The technical solutions of the present invention and how the technical solutions of the present invention solve the above technical problems will be described in detail below with specific embodiments. These several specific embodiments may be combined with each other. For the same or similar concepts or processes, they may not be repeated in some embodiments. The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0031] As Figure 1 shown, a bench test method for a power shift system according to an embodiment of the present invention includes the following steps:

[0032] S1. Control the power shift system to drive the inertia loading device for rotation testing and collect operation data;

[0033] S2. Determine whether the power shift system meets the design requirements according to the collected operation data.

[0034] Optionally, in the above technical solution, it further includes: providing power input for the power shift system through an input dynamometer, and the inertia loading device is mounted with inertia according to a preset working condition.

[0035] Optionally, in the above technical solution, the operation data includes: the input speed and output speed of the clutch of the power shift system, the input pressure and output pressure of the solenoid valve used by the clutch, and the input torque and output torque of the gearbox using the power shift system.

[0036] Optionally, in the above technical solution, the power shift system is: the power shift system of agricultural machinery and equipment, where the agricultural machinery and equipment can be agricultural tractors, corn harvesters, wheat harvesters, etc.

[0037] Combined with Figure 2 and Figure 3 , the present invention is described as follows:

[0038] As Figure 2As shown in the figure, the input dynamometer provides power input for the power shift clutch to be tested. The inertia loading device mounts inertia according to the actual working conditions. The controller controls the pressure output by the solenoid valve, controls the power shift clutch to engage and transmit power, the power shift clutch drives the inertia to start rotating, the controller reads the signals of each sensor to compensate for the control situation, and the engineer judges the control result through the calibration terminal and modifies and calibrates the control program according to the result.

[0039] As Figure 3 shown, the test method is as follows:

[0040] S101. Control the power shift system to drive the inertia loading device for rotation test. Specifically:

[0041] Engage the specified gear. At this time, the power shift wet clutch is disengaged. Raise the motor speed of the input dynamometer to the specified speed. The controller controls the wet clutch to start engaging, and the clutch drives the rear inertia block to start rotating. When the engagement rate of the clutch (the rotational speed of the clutch output end / the rotational speed of the input end) reaches 100%, keep it for 5 s and then disengage the clutch, and wait for the loaded inertia block to decelerate to 0.

[0042] S102. During the rotation test, collect and store the operation data. The operation data includes: the input rotational speed and output rotational speed of the clutch of the power shift system, the input pressure and output pressure of the solenoid valve used by the clutch, and the input torque and output torque of the gearbox using the power shift system.

[0043] S103. Calculate the acceleration of the output end according to the operation data, judge whether the acceleration meets the design requirements, and obtain the judgment result. When the judgment result is yes, it is determined that the power shift system meets the design requirements. When the judgment result is no, adjust the control program for "raising the motor speed of the input dynamometer to the specified speed", and return to execute S101 until the judgment result is yes.

[0044] If, after adjusting the control program multiple times, the ideal test result still cannot be achieved, that is, the judgment result is always no, then it is necessary to consider improving the power shift mechanical structure.

[0045] The present invention can complete the test, experiment, and calibration of the power shift system during the gearbox development stage, ensure that there are no obvious design shortcomings in the power shift system itself, and prevent repeated rectification in the later stage of the whole vehicle product development.

[0046] In the above embodiments, although the steps are numbered S1, S2, etc., they are only specific embodiments given by the present invention.
