[0018] Some embodiments of the present invention are shown by examples and should not be construed as limiting the scope of the present invention. Improvements can be made to the disclosed content of the present invention in terms of materials, methods, and reaction conditions simultaneously, and all these improvements should fall within the spirit and scope of the present invention.

[0019] As Figures 1-4 shown, a hydraulic transmission simulation device includes a simulation valve body 2 and a handle 1 vertically penetrating the simulation valve body 2. A bobbin screw 3 is fixed on the rotating shaft of the handle 1. The bobbin screw 3 protrudes from the surface of the rotating shaft by a certain height, which can ensure rotation within two layers of partition plates without cross-layer (cross-gear) occurrence; the simulation valve body 2 includes an upper pressure plate 4 and a bottom pressure plate 5, and the upper pressure plate 4 and the bottom pressure plate 5 block the bobbin screw 3 for axial limit; several layers of gear position plates 6 and partition plates 7 are alternately arranged between the upper pressure plate 4 and the bottom pressure plate 5. Proximity switches / microswitches 8 for controlling different hydraulic circuits are respectively provided on different layers of the gear position plates 6, and multiple proximity switches / microswitches 8 for controlling different gears of the same hydraulic circuit are provided on the same layer of the gear position plate 6. The spherical head of the bobbin screw 3 blocks the proximity switch or touches the microswitch to send a signal, and each proximity switch / microswitch 8 is respectively connected to a control computer, and the computer simulates different gear scenarios according to the corresponding signals or sends corresponding signals.

[0020] In this embodiment, the proximity switch / microswitch 8 is fixedly connected to the gear plate 6 by means of a threaded connection. The position of the switch within the mounting hole can be adjusted by means of the nut on the switch to meet the appropriate requirements.

[0021] In this embodiment, the upper pressure plate 4, several layers of gear plates 6, several layers of partition plates 7 and the bottom pressure plate 5 are fixedly formed by means of screws 9.

[0022] In this embodiment, a slot 10 for preventing the rotating shaft from rotating in the non-gear direction is provided inside the gear plate 6; several switch mounting holes 11 for mounting the proximity switch / microswitch 8 are circumferentially distributed on the gear plate 6, which are used for mounting the proximity switch / microswitch 8 and limiting the wave stud screw 3 to achieve gear setting.

[0023] In this embodiment, several shifting slots 12 are circumferentially distributed inside the partition plate 7, which facilitates the axial movement of the handle 1 to realize the control of different hydraulic circuits in the same gear.

[0024] During use, rotating the handle drives the wave stud screw to rotate within the gear area of the same layer of gear plate (to realize the adjustment of different gears in the same hydraulic circuit). When the spherical head of the wave stud screw blocks a certain proximity switch or touches the microswitch to send a signal, the computer simulates the scenarios of different gears according to the corresponding signal or sends out the corresponding signal; when it is necessary to switch to control different hydraulic circuits, the handle moves axially, the wave stud screw passes through the shifting slot of the partition plate, and moves to the layer of gear plate where the proximity switch / microswitch for controlling this hydraulic circuit is located, and then rotating the handle drives the wave stud screw to rotate to realize the adjustment of different gear speeds in the same hydraulic circuit.

[0025] The functions of the hydraulic transmission device are simulated using electronic devices and mechanical structures. The signals generated when the spherical head of the wave stud screw blocks the proximity switch or touches the microswitch are directly processed by the computer. The structure is small in size and does not cause oil pollution; the alternately arranged multiple layers of gear plates and partition plates are used to simulate more gears.

[0026] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present invention.
