Problems solved by technology

[0003] The speed difference between adjacent gears in the ordinary motor transmission system is small, generally about 1.5 times. It is still feasible to use the traditional shift control method to control the clutch mechanism, but the speed difference between adjacent gears in the hydraulic motor transmission system is relatively large, up to About 3 times, such a large speed difference and then using the traditional shift control method will cause a large impact between the driving disc and the driven disc of the clutch, causing damage to the components, and will cause uneven shifting and affect the A series of issues such as gear shift quality and machine operation quality

Abstract

The invention discloses a transmission system shifting control method of a hydraulic motor. The method comprises the steps of interrupting shift: interrupting an original shift clutch; adjusting speed: adjusting the flow of a hydraulic pump, and changing the rotation speed of the hydraulic motor, thus reducing the rotation speed difference of a driving disc and a driven disc of an objective shift clutch within a certain preset value; and engaging shift, controlling the objective shift clutch to be connected. With the adoption of the transmission system shifting control method of the hydraulic motor, the impact between the driving disc and the driven disc of the clutch while shifting is reduced greatly, and the shifting quality is improved.

Description

technical field [0001] The invention relates to a shift control method, in particular to a shift control method of a hydraulic motor transmission system. Background technique [0002] The hydraulic motor transmission system is commonly used in the gear shifting mechanism of the vehicle. The general hydraulic motor transmission system can include: hydraulic pump, hydraulic motor, gearbox, drive axle, driving wheel, etc. The above-mentioned components are connected in sequence, and the power is provided by the hydraulic pump. and the output of the hydraulic motor, and then sequentially transmitted to the driving wheels, where the existing dual-clutch mechanism can be integrated on the gearbox and connected to the output shaft of the hydraulic motor to control the on-off connection between the hydraulic motor and the gearbox to achieve Gear shifting, the whole process is controlled by computer systems and other control devices. [0003] The speed difference between adjacent ge...
