Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
As shown in fig. 1, an embodiment of the present invention provides a hydraulic control system for a clutch, including: an oil supply path 1; the oil cylinder loop 2 of the sliding part comprises a first electromagnetic directional valve 21, a high-pressure oil path 22, a low-pressure oil path 23 and a sliding part oil cylinder 24, the first electromagnetic directional valve 21 is set to be a 2-position 3-way electromagnetic valve, an inlet of the first electromagnetic directional valve 21 is connected with the oil supply path 1, the high-pressure oil path 22 and the low-pressure oil path 23 are arranged in parallel, an inlet of the high-pressure oil path 22 and an inlet of the low-pressure oil path 23 are both connected with an outlet of the first electromagnetic directional valve 21 (namely two outlets of the first electromagnetic directional valve 21 are respectively connected with an inlet of the high-pressure oil path 22 and an outlet of the low-pressure oil path 23), and an outlet of the high-pressure oil path 22 and an outlet of the low-.
In the embodiment, in the process that the oil supply path 1 supplies oil to the high-pressure oil path 22 and the low-pressure oil path 23, the connection between the first electromagnetic directional valve 21 and the high-pressure oil path 22 may be closed first, and the connection between the first electromagnetic directional valve 21 and the low-pressure oil path 23 may be opened, at this time, the oil supply path 1 may supply oil to the sliding piece oil cylinder 24 only through the low-pressure oil path 23, so that a smaller pressure may be generated to drive the sliding piece oil cylinder 24 to start the clutch; when the sliding part oil cylinder 24 is started, the connection between the first electromagnetic directional valve 21 and the low-pressure oil path 23 is closed, and the connection between the first electromagnetic directional valve 21 and the high-pressure oil path 22 is opened, at the moment, the oil supply path 1 only supplies oil to the sliding part oil cylinder 24 through the high-pressure oil path 22, so that larger pressure can be generated to drive the sliding part oil cylinder 24 to drive the clutch to stably operate.
In the present embodiment, by using the first electromagnetic directional valve 21, the high-pressure oil path 22 and the low-pressure oil path 23, the oil supply oil path 1 can supply oil to the sliding piece oil cylinder 24 through the low-pressure oil path 23 or the high-pressure oil path 22 respectively by adjusting the first electromagnetic directional valve 21 during the driving process of the clutch so as to drive the clutch. Therefore, the clutch can be started with smaller force by switching the first electromagnetic directional valve 21 to the low-pressure oil way 23 for oil supply at the starting stage of the clutch, and the damage of structures such as a sliding part oil cylinder 24 and the like caused by overlarge pressure in the starting process is avoided; in addition, the first electromagnetic directional valve 21 can be switched to the high-pressure oil path 22 to supply oil to drive the clutch with larger force in the running process of the clutch, so that the unstable running of the clutch caused by too small driving pressure is avoided.
Optionally, to ensure the operational effects of the high-pressure oil path 22 and the low-pressure oil path 23, the high-pressure oil path 22 includes a first pressure reducing valve 221, the low-pressure oil path 23 includes a second pressure reducing valve 231, an inlet of the first pressure reducing valve 221 and an inlet of the second pressure reducing valve 231 are both connected to an outlet of the first electromagnetic directional valve 21 through a pipeline, and an outlet of the first pressure reducing valve 221 and an outlet of the second pressure reducing valve 231 are both connected to the slider cylinder 24 through a pipeline.
In the embodiment, the first pressure reducing valve 221 and the second pressure reducing valve 231 are respectively arranged on the high-pressure oil path 22 and the low-pressure oil path 23, the output pressure of the first pressure reducing valve 221 is set to be 1.5MPa-2.5MPa, and the output pressure of the second pressure reducing valve 231 is set to be 0.5MPa-1.5MPa, when the sliding part oil cylinder 24 is started, the connection between the first electromagnetic directional valve 21 and the first pressure reducing valve 221 is closed and the connection between the first electromagnetic directional valve 21 and the second pressure reducing valve 231 is opened, so that the pressure of the working oil input into the sliding part oil cylinder 24 is between 0.5MPa and 1.5MPa, and the sliding part oil cylinder 24 can be driven, and the sliding part oil cylinder 24 can be prevented from being damaged by suddenly applied high pressure; after a period of time, the connection between the first electromagnetic directional valve 21 and the first pressure reducing valve 221 is opened and the connection between the first electromagnetic directional valve 21 and the second pressure reducing valve 231 is closed, so that the pressure of the working oil input into the slip cylinder 24 is between 1.5MPa and 2.5MPa, and therefore, sufficient pressure can be ensured to drive the slip cylinder 24 to move without interruption, thereby ensuring the stability of the operation of the clutch.

Meanwhile, since the first electromagnetic directional valve 21 closes the connection with the second reducing valve 231 during driving of the slider cylinder 24, the working oil cannot flow back into the oil tank 11 through the low-pressure oil passage 23, and therefore, only the problem of backflow on the high-pressure oil passage 22 needs to be considered. By arranging the check valve 222 on the high-pressure oil path 22, connecting the inlet of the check valve 222 with the outlet of the first pressure reducing valve 221, and connecting the outlet of the check valve 222 with the sliding member cylinder 24 through a pipeline, the oil transportation direction between the oil tank 11 and the sliding member cylinder 24 can only be from the oil tank 11 to the sliding member cylinder 24, thereby preventing the working oil in the sliding member cylinder 24 from flowing backwards.
Optionally, to adjust the oil return rate of the slide cylinder 24, the slide cylinder circuit 2 of the present embodiment further includes an oil return path 25 connected to the slide cylinder 24, and an adjustable throttle 251 provided on the oil return path 25.

Optionally, in order to further ensure the stability of the operation of the clutch, the hydraulic control system of the clutch of the present embodiment further includes a lubrication circuit 4 connected to the oil supply passage 1.
