Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0019] Due to the application occasions and use requirements of the marine friction clutch, it needs to have the characteristics of high integration and stable reliability.

[0020] Therefore, the application provides a segmented adjustable high-integration clutch control valve group to solve the above problems. The application will be described in detail below with reference to the accompanying drawings. Figure 1 The application will be described in detail below.

[0021] The segmented adjustable high-integration clutch control valve group comprises a control valve body, and an electromagnetic reversing valve is arranged on each oil passage of the control valve body.

[0022] In one embodiment, the number of electromagnetic reversing valves is 2.

[0023] In one embodiment, two electromagnetic reversing valves are arranged on the main push clutch oil passage and the water cannon clutch oil passage of the control valve body, respectively.

[0024] In one embodiment, the electromagnetic reversing valve arranged on the main push clutch oil passage has a valve core in the main push clutch oil passage of the control valve body.

[0025] In one embodiment, when the electromagnetic reversing valve arranged on the main push clutch oil passage is powered, the main push clutch oil passage is conducted, so that the oil can enter the working oil cavity of the main push clutch through the control valve body.

[0026] In one embodiment, the electromagnetic reversing valve arranged on the water cannon clutch oil passage has a valve core in the water cannon clutch oil passage of the control valve body.

[0027] In one embodiment, when the electromagnetic reversing valve arranged on the water cannon clutch oil passage is powered, the water cannon clutch oil passage is conducted, so that the oil can enter the working oil cavity of the water cannon clutch through the control valve body.

[0028] In one embodiment, the two electromagnetic reversing valves are in interlocking structure.

[0029] In one embodiment, the same number of adjustment knobs as the electromagnetic reversing valves are further included, and the adjustment knobs are used to adjust the engagement and disengagement time of different clutches.

[0030] In one embodiment, two adjustment knobs are further included, and the two adjustment knobs are used to adjust the engagement and disengagement time of the main push clutch and the water cannon clutch, respectively.

[0031] The application will be described in detail below.

[0032] The segmented adjustable high-integration clutch control valve group comprises a control valve body 1 and two electromagnetic reversing valves 2, which can meet the requirements of precise control of the engagement and disengagement of the clutch of the transmission device.

[0033] The spool of one electromagnetic reversing valve 2 is embedded in the main push clutch oil passage of the control valve body 1. When the electromagnetic reversing valve 2 is powered, the electromagnetic reversing valve 2 is turned on, the main push clutch oil passage is connected, and the oil can enter the main push clutch working oil chamber. When the electromagnetic reversing valve 2 is powered off, the electromagnetic reversing valve 2 is turned off, the main push clutch oil passage is disconnected, and the oil cannot enter the main push clutch working oil chamber.

[0034] The spool of another electromagnetic reversing valve 2 is embedded in the water cannon clutch oil passage of the control valve body 1. When the electromagnetic reversing valve 2 is powered, the electromagnetic reversing valve 2 is turned on, the water cannon clutch oil passage is connected, and the oil can enter the water cannon clutch working oil chamber. When the electromagnetic reversing valve 2 is powered off, the electromagnetic reversing valve 2 is turned off, the water cannon clutch oil passage is disconnected, and the oil cannot enter the water cannon clutch working oil chamber.

[0035] The two electromagnetic reversing valves 2 are interlocked to prevent the two clutches from being filled with oil at the same time.

[0036] Through the integrated design of the electromagnetic valve, the clutch control valve group can be controlled by the respective electromagnetic reversing valve 2 of different clutches. The electromagnetic reversing valve 2 is integrated with the control valve body 1 on a valve block, with a power-off position holding and manual switching function.

[0037] The clutch control valve group can divide the oil into two paths, one for gearbox lubrication and the other for clutch on-off control. The clutch control valve group has the functions of electric control, manual control, and power-off holding.

[0038] The working principle of the control valve group is as follows: when the transmission device needs to be operated for on-off operation, the on-off instruction is given by the monitoring system, the electromagnetic reversing valve 2 is actuated, the oil in the hydraulic system enters the control valve group through the oil inlet, and the high-pressure lubricating oil for the clutch is output through the control valve body 1. Conversely, when the monitoring system gives the off instruction, the clutch off operation is realized by the action of the electromagnetic reversing valve 2. The electromagnetic reversing valve 2 can switch the adjustment knob I and the adjustment knob II to be used, and can realize the on-off time requirements of different clutches.

It is therefore to be understood that numerous modifications can be made to the illustrative embodiments and that other arrangements can be devised without departing from the spirit and scope of the present application as defined by the appended claims. It is to be understood that the features of the dependent claims can be combined with those of the parent application in the manner set forth in the description above. It is also to be understood that features described with respect to one embodiment can be used in other embodiments.
