[0026] Due to the angle of the drawing, some parts may not be drawn, but their positions and connection relationships can be understood according to the textual expression part.

[0027] As shown in Figure 1 , the present application is a kind of automatic clutch type laminated flexible coupling, including interval shaft clutch assembly 2, interval shaft clutch assembly 2 both sides are connected with mounting disc assembly 1, interval shaft clutch assembly 2 is driven by hydraulic shift fork unit 3.

[0028] As shown in Figure 2 , interval shaft clutch assembly 2 both sides are left adapter disc 2-10 and right adapter disc 2-9 respectively, left adapter disc 2-10 and right adapter disc 2-9 inner end are fixedly connected with left adapter shaft 2-1 and right adapter shaft 2-6 respectively, flexible diaphragm 2-8 is installed between left adapter disc 2-10 and left adapter shaft 2-1, and between right adapter disc 2-9 and right adapter shaft 2-6, left adapter shaft 2-1 and right adapter shaft 2-6 outer periphery are slidably connected with slide sleeve 2-3 through spline structure, axial positioning mechanism is arranged between slide sleeve 2-3 and left adapter shaft 2-1, circumferential guide mechanism is arranged between slide sleeve 2-3 and right adapter shaft 2-6, left adapter shaft 2-1 and right adapter shaft 2-6 are supported by bearing 2-4 for centering and relative rotation.

[0029] The inner periphery of the right side of the slide sleeve 2-3 is provided with an internal spline, and the outer periphery of the middle part of the left adapter shaft 2-1 and the left side of the outer periphery of the right adapter shaft 2-6 are provided with matching external splines.

[0030] The axial positioning mechanism keeps the slide sleeve 2-3 in the interval shaft clutch assembly 2 in a stable position when working. The axial positioning mechanism includes a positioning ring groove and a spring plunger 2-2. Two positioning ring grooves are opened on the left inner periphery of the slide sleeve 2-3, which are respectively connected positioning ring groove 2-31 and disengaging positioning ring groove 2-32, and the connected positioning ring groove 2-31 is closer to the left adapter disc 2-10 than the disengaging positioning ring groove 2-32. A plurality of spring plungers 2-2 are evenly distributed on the left outer periphery of the left adapter shaft 2-1 in a ring shape. In the non-positioning state, the spring plunger 2-2 is in contact with the left inner periphery of the slide sleeve 2-3. When the slide sleeve 2-3 is driven by the hydraulic shift fork unit 3 to the connecting position, the connected positioning ring groove 2-31 moves right to the same vertical plane as the spring plunger 2-2, the spring plunger 2-2 extends and is embedded in the connected positioning ring groove 2-31, and the left adapter shaft 2-1, the right adapter shaft 2-6 and the slide sleeve 2-3 are driven by the spline structure. When the slide sleeve 2-3 is driven by the hydraulic shift fork unit 3 to the disengaging position, the disengaging positioning ring groove 2-32 moves left to the same vertical plane as the spring plunger 2-2, the spring plunger 2-2 extends and is embedded in the disengaging positioning ring groove 2-32, the left adapter shaft 2-1 and the slide sleeve 2-3 are driven by the spline structure, and the right adapter shaft 2-6 and the slide sleeve 2-3 are in the disengaging state.

[0031] The function of the circumferential guiding mechanism is to ensure that when the sliding sleeve 2-3 moves laterally towards the right transition shaft 2-6, the inner spline of the sliding sleeve 2-3 and the outer spline of the right transition shaft 2-6 can smoothly slide into each other without interference. The circumferential guiding mechanism includes a first guide bevel tooth surface 2-33 and a second guide bevel tooth surface 2-61. The first guide bevel tooth surface 2-33 is located on the right end face of the inner spline on the sliding sleeve 2-3, and the second guide bevel tooth surface 2-61 is located on the left end face of the outer spline on the right transition shaft 2-6. When the sliding sleeve 2-3 approaches the right transition shaft 2-6, the first guide bevel tooth surface 2-33 remains stationary, and the second guide bevel tooth surface 2-61 contacts the first guide bevel tooth surface 2-33 and rotates along the contact surface until the sliding sleeve 2-3 moves laterally to the outer circumference of the right transition shaft 2-6, and the spline structure completes engagement.

[0032] To prevent the first guide bevel tooth surface 2-33 from contacting the right transition shaft 2-6 and damaging the guide, a spacer plate 2-5 is installed on the right side of the sliding sleeve 2-3. The spacer plate 2-5 is closer to the right transition shaft 2-6 than the first guide bevel tooth surface 2-33 to prevent interference between the first guide bevel tooth surface 2-33 and the right transition shaft 2-6.

[0033] The bearing 2-4 is installed on the inner circumference of the left side of the right transition shaft 2-6, and the right end of the left transition shaft 2-1 is located in the inner ring of the bearing 2-4.

[0034] like Figures 3-4 As shown, the hydraulic shift fork unit 3 includes a base 3-7, on which a shift fork cylinder 3-1 and a support seat 3-6 are mounted. The two ends of the shift fork piston rod slide within the shift fork cylinder 3-1 and the support seat 3-6. A shift fork 3-3 is sleeved in the middle of the shift fork piston rod, and a sleeve 3-4 is mounted on the upper part of the shift fork 3-3. A spring-loaded structure is provided between the shift fork piston rod and the shift fork cylinder 3-1 and the support seat 3-6. An axial positioning mechanism is provided between the shift fork 3-3 and the base 3-7, and sensors 3-8 are located on both sides of the axial positioning mechanism.

[0035] The springback structure ensures that after the hydraulic control system stops operating, the second plunger spring 3-9 at the bottom of the shift fork piston rod is pushed into the positioning groove on the base 3-7 by the springback force, thus fixing the position of the shift fork piston rod. Simultaneously, the small-amplitude springback provided by the springback structure allows the sleeve 3-4 on the shift fork groove of the push sleeve 2-3 to retract slightly after completing its pushing action, preventing contact with the shift fork groove. The springback structure includes a spring 3-10, which is installed at both ends of the shift fork piston rod. Matching spring bosses are provided on the inner walls of the shift fork cylinder 3-1 and the support base 3-6.

[0036] Specifically, spring holes are opened at both ends of the shift fork piston rod, and springs 3-10 are located in them and are limited by retaining rings.

[0037] The axial positioning mechanism of the shift fork 3-3 keeps the shift fork 3-3 stable during work. The axial positioning mechanism of the shift fork 3-3 includes a shift fork positioning ring groove and a second spring plunger 3-9. Two shift fork positioning grooves are formed on the top surface of the base 3-7, which are a shift fork connection positioning groove and a shift fork disconnection positioning ring groove, respectively. The shift fork connection positioning groove is closer to the left adapter disc 2-10 than the shift fork disconnection positioning ring groove. The second spring plunger 3-9 is installed at the bottom of the shift fork 3-3.

[0038] Two sensors 3-8 are fixed on the base 3-7 and below the shift fork oil cylinder 3-1 side and the support seat 3-6 side, respectively. The sensor 3-8 is a proximity switch. The sensor 3-8 is connected to the hydraulic control system, and the hydraulic control system is connected to the shift fork oil cylinder 3-1.

[0039] The outer periphery of the sliding sleeve 2-3 is provided with a shift fork groove, and the sleeve 3-4 is located in the shift fork groove to push the sliding sleeve 2-3 left and right. In order to prevent contact damage to the sliding sleeve 2-3, the sleeve 3-4 is made of soft polymer material.

[0040] The shift fork piston rod adopts a split structure, which is composed of a left sliding shaft 3-2 and a right sliding shaft 3-5 connected by bolts. The shift fork oil cylinder 3-1 and the support seat 3-6 jointly support the left sliding shaft 3-2, the right sliding shaft 3-5, and the shift fork 3-3, the installation sleeve 3-4 to form a shift fork system, which can freely slide left and right under the action of the electric hydraulic control system.

[0041] In actual work, the entire system only has two working positions, namely the connection working position and the disconnection working position. The initial state is the disconnection state of the driving machine and the driven machine. At this time, the disconnection ring groove 2-32 on the sliding sleeve 2-3 corresponds to the spring plunger 2-2 on the left adapter shaft 2-1, the spring plunger 2-2 is embedded in the disconnection ring groove 2-32, and the sliding sleeve 2-3 is in a fixed state. At this time, the inner spline on the sliding sleeve 2-3 and the outer spline on the right adapter shaft 2-6 are in a disconnected state, so that the left adapter shaft 2-1 can rotate relative to the right adapter shaft 2-6 with the sliding sleeve 2-3 supported by the bearing 2-4. That is, the driving machine and the driven machine are disconnected and rotate independently. At the same time, in this state, the second spring plunger at the bottom of the shift fork 3-3 in the bottom hydraulic shift fork unit 3 corresponds to the positioning groove on the left side of the base 3-7, the second spring plunger is embedded in the positioning groove, and the shift fork 3-3 is in a fixed state. The installation sleeve 3-4 on the shift fork 3-3 is located in the middle position of the sliding groove on the sliding sleeve 2-3 and does not contact the rotating sliding sleeve.

[0042] When the electric control hydraulic system sends a connection instruction, hydraulic oil will be injected into the left cavity of the yoke oil cylinder, driving the yoke system composed of the left sliding shaft 3-2, the right sliding shaft 3-5 and the yoke 3-3 to slide to the right. At this time, the second spring plunger 3-9 will be pushed out of the left positioning groove under the action of the hydraulic oil, contact the top surface of the base plate, and continue to slide to the right until the second spring plunger 3-9 slightly exceeds the right positioning ring groove. At this position, the sensor 3-8 will sense the signal and give feedback to stop the hydraulic oil injection action. In this state, the inner spline on the sliding sleeve 2-3 is in a connected state with the outer spline on the right adapter shaft 2-6, and the connection positioning ring groove 2-31 on the sliding sleeve 2-3 corresponds to the spring plunger 2-2 on the left adapter shaft 2-1. The spring plunger 2-2 is embedded in the connection positioning ring groove 2-31, so that the sliding sleeve 2-3 is in a connected state and remains in this position, and the driving and driven mechanisms are connected. At the same time, in this state, the spring in the right sliding shaft 3-5 is pressed against the boss on the support seat 3-6 and is in a compressed state. After the sensor 3-8 sends a stop injection instruction, the hydraulic oil disappears. Since the second spring plunger 3-9 has slightly exceeded the right positioning groove, it is in contact with the top surface of the base 3-7 at this time, and the friction is low, so it cannot resist the spring rebound force. The spring rebound force pushes the yoke system to retract to the left until the second spring plunger 3-9 is embedded in the right positioning groove on the base plate 3-7, and the force reaches equilibrium. At this time, the final position of the yoke 3-3 relative to the final position of the sliding sleeve 2-3 will retract slightly, and the sleeve 3-4 will be out of contact with the yoke groove on the sliding sleeve 2-3, so that the coupling does not rub when it operates. It should be understood that the second spring plunger 3-9 is first pushed out of the left positioning groove and then exceeds the right positioning groove to reach the sensor 3-8 sensing position during the right movement. The driving force of the yoke oil cylinder 3-1 is greater than the friction force of the second spring plunger 3-9 and the yoke disengagement positioning ring groove at this time. The final position of the sliding sleeve 2-3 is in a connected state, and the first spring plunger 2-2 is embedded in the connection positioning groove 2-31, but it is not the final position of the second spring plunger 3-9. Since the sensor 3-8 senses the signal at this time, it will send a stop injection instruction, and the compressed spring in the right sliding shaft will start to provide a rebound force to push the yoke 3-3 to the left by a small distance. The second plunger spring 3-9 is embedded in the right positioning groove on the base plate 3-7, and the yoke 3-3 reaches its final position. The purpose of this is to make the sleeve 3-4 installed on the yoke 3-3 always in contact with the sliding sleeve 2-3 during the aforementioned right pushing process, and then become a non-contact state by retracting slightly to the left, so as to prevent the coupling from rubbing when it operates.

[0043] When the electric control hydraulic system sends a disengaging instruction, hydraulic oil will be injected into the right cavity of the shift fork oil cylinder, driving the shift fork system composed of the left sliding shaft 3-2, the right sliding shaft 3-5 and the shift fork 3-3 to slide to the left. At this time, the second spring plunger 3-9 will be pushed out of the right positioning groove under the action of the hydraulic oil, contact the top surface of the base plate, and continue to slide to the left until the second spring plunger 3-9 slightly exceeds the left positioning groove. At this position, the sensor 3-8 will sense the signal and make a feedback to stop the hydraulic oil injection action. In this state, the inner spline on the sliding sleeve 2-3 and the outer spline on the right adapter shaft 2-6 are in a disengaged state, and the disengaging positioning groove 2-32 on the sliding sleeve 2-3 corresponds to the spring plunger 2-2 on the left adapter shaft 2-1. The spring plunger 2-2 is embedded in the disengaging positioning groove 2-32, so that the sliding sleeve 2-3 is in a disengaged state and remains in this position, and the driving and driven machines are disengaged. At the same time, in this state, the spring in the left sliding shaft 3-2 is pressed against the boss on the shift fork oil cylinder 3-1 and is in a compressed state. After the sensor 3-8 sends a stop injection instruction, the hydraulic oil disappears. Since the second spring plunger 3-9 has slightly exceeded the left positioning groove, it is in contact with the top surface of the base 3-7 at this time, and the friction is low, which cannot resist the spring rebound force. The spring rebound force pushes the shift fork system to retract to the right until the second spring plunger 3-9 is embedded in the left positioning groove on the base plate 3-7, and the force reaches equilibrium. At this time, the final position of the shift fork 3-3 relative to the final position of the sliding sleeve 2-3 will retract slightly, and the sleeve 3-4 will be out of contact with the shift fork groove on the sliding sleeve 2-3, so that the coupling does not rub when it operates. It should be understood that the second spring plunger 3-9 is first pushed out of the right positioning groove and then exceeds the left positioning groove to reach the sensing position of the sensor 3-8 during the left movement. Because the driving force of the shift fork oil cylinder 3-1 is greater than the friction between the second spring plunger 3-9 and the shift fork positioning ring groove. At this time, the final position of the sliding sleeve 2-3 is in a disengaged state, and the first spring plunger 2-2 is embedded in the disengaging positioning groove 2-32, but it is not the final position of the second spring plunger 3-9. Since the sensor 3-8 senses the signal at this time, it will send a stop injection instruction, and the compressed spring in the left sliding shaft 3-2 will start to provide a rebound force to push the shift fork 3-3 to the right by a small distance, so that the second plunger spring 3-9 is embedded in the left positioning groove on the base plate 3-7, and the shift fork 3-3 reaches its final position. The purpose of this is to make the sleeve 3-4 installed on the shift fork 3-3 always in contact with the sliding sleeve 2-3 during the aforementioned left pushing process, and then become a non-contact state by retracting slightly to the right, so as to prevent the coupling from rubbing when it operates.

[0044] The mounting disc assembly 1 includes a mounting disc 1-1, and the spacer shaft clutch assembly 2 is connected to the mounting disc 1-1 on both sides through a torque bolt 1-2. An adjusting pad 1-3 is arranged between the mounting disc 1-1 and the adapter disc 2-9, which adjusts the axial length of the coupling to adapt to the axial length of the machine set.

[0045] The mounting discs 1-1 on both sides are connected to the main shaft of the driving device and the main shaft of the driven device respectively.

[0046] It can be understood that the above embodiments are only exemplary embodiments for illustrating the principles of the present application, and the present application is not limited thereto. Various modifications and improvements can be made by those of ordinary skill in the art without departing from the spirit and essence of the present application, and these modifications and improvements are also considered to be within the scope of protection of the present application.
