[0060] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0061] Example

[0062] like Figures 1 to 9 As shown, the present invention provides an inertia energy-saving device for mechanical transmission, the device comprising:

[0063] An input transmission member 1, one end of which is rigidly connected to a power source;

[0064] The output transmission member 11 is coaxial and sleeved on the other end of the input transmission member 1. The output transmission member 11 is connected to the input transmission member 1 through a composite controllable overrunning clutch device 26. The composite controllable overrunning clutch device 26 has at least three transmission modes:

[0065] In the first transmission mode, the composite controllable overrunning clutch device 26 is rigidly connected between the input transmission member 1 and the output transmission member 11, and can transmit forward driving torque, reverse driving torque and reverse driving torque; in the second transmission mode, the composite controllable overrunning clutch device 26 can only transmit forward driving torque, and cannot transmit reverse driving torque and reverse driving torque; in the third transmission mode, in the second transmission mode, the driving torque of the power source is reduced, or the driving torque of the power source is interrupted, and the composite controllable overrunning clutch device 26 is in a forward overrunning state, and does not transmit driving torque, that is, the transmission system is in an inertia energy-saving operation transmission mode;

[0066] The transmission control mechanism 27 is used to control the transmission mode of the compound controllable overrunning clutch device 26 .

[0067] Specifically, a composite controllable overrunning clutch device 26 is arranged between the input transmission member 1 and the output transmission member 11 of the device, which changes the rigid connection structure between the input transmission member 1 and the output transmission member 11 in the traditional mechanical transmission. According to the working conditions and scenes of the mechanical transmission device, under the premise of safety, the composite controllable overrunning clutch device 26 can be switched to the inertial energy-saving operation transmission mode in priority, which not only overcomes the reverse drive problem in the traditional mechanical transmission, but also eliminates the additional energy consumption and wear of the mechanical transmission system caused by the reverse drive of the mechanical transmission, improves the service life of the mechanical transmission system, and saves a lot of mechanical maintenance and repair costs. In the inertial energy-saving operation transmission mode, the transmission system placed before the composite controllable overrunning clutch device 26 is basically in low-intensity operation or stopped, and a large amount of energy consumption tends to the lowest point, so that the inertial energy can be fully utilized and the energy of the power source is minimized.

[0068] Furthermore, the transmission modes of the compound controllable overrunning clutch device 26 include a rigid transmission mode (the first transmission mode), a forward transmission mode (the second transmission mode) and an inertia energy-saving operation transmission mode (the third transmission mode). In the rigid transmission mode, the reverse transmission member 9 in the compound controllable overrunning clutch device 26 engages with the reverse conjugate surface 23 in the annular structure of the output transmission member 11, and the forward transmission member 14 engages with the forward conjugate surface 24 in the annular structure of the output transmission member 11; at this time, the compound controllable overrunning clutch device 26 can transmit forward, reverse and reverse driving torques; in the forward transmission mode, the reverse transmission member 9 in the compound controllable overrunning clutch device 26 disengages from the reverse conjugate surface 23 in the annular structure of the output transmission member 11, and is locked by the dial block on the dial 16, and the forward transmission member 14 engages with the forward conjugate surface 24 in the annular structure of the output transmission member 11, and can only transmit forward driving torque, but cannot transmit reverse torque. Driving torque and reverse driving torque; in the inertia energy-saving operation transmission mode, in the compound controllable overrunning clutch device 26, the reverse transmission member 9 is disengaged from the reverse conjugate surface 23 in the annular structure of the output transmission member 11, and is locked by the dial block on the dial 16, and the forward transmission member 14 is disengaged from the forward conjugate surface 24 in the annular structure of the output transmission member 11. At this time, the rotation speed of the input transmission member 1 is lower than the rotation speed of the output transmission member 11, and the compound controllable overrunning clutch device 26 does not transmit driving torque, and the mechanical transmission device enters the inertia energy-saving operation transmission mode. At this time, the supply of input power energy can be reduced or interrupted, and the inertia can be fully utilized to realize the operation of the mechanism on the output transmission member 11, thereby achieving the purpose of high efficiency and energy saving.

[0069] In this embodiment, the composite controllable overrunning clutch device 26 comprises:

[0070] A forward transmission member 14 and a reverse transmission member 9, wherein the forward transmission member 14 and the reverse transmission member 9 are arranged between the input transmission member 1 and the output transmission member 11;

[0071] The forward and reverse transmission member support springs 15 can elastically support the forward transmission member 14 to engage with the forward conjugate surface 24 of the output transmission member 11, and only transmit the forward driving torque; the forward and reverse transmission member support springs 15 can elastically support the reverse transmission member 9 to engage with the reverse conjugate surface 23 of the output transmission member 11 when the reverse transmission member 9 is released. At this time, the forward transmission member 14 and the reverse transmission member 9 are respectively engaged with the forward conjugate surface 24 and the reverse conjugate surface 23 of the output transmission member 11, and can transmit the forward driving torque, the reverse driving torque and the reverse driving torque.

[0072] Specifically, in the rigid transmission mode, the forward transmission member 14 and the reverse transmission member 9 are respectively engaged with the forward conjugate surface 24 and the reverse conjugate surface 23 in the annular structure of the output transmission member 11 under the action of the forward and reverse transmission member support springs 15; and when switching from the rigid transmission mode to the forward transmission mode and the inertial energy-saving operation transmission mode, the dial 16 is driven to press the reverse transmission member 9 through its shift block, overcome the support of the forward and reverse transmission member support springs 15 on the reverse transmission member 9, so that the reverse transmission member 9 is no longer engaged with the reverse conjugate surface 23 in the annular structure of the output transmission member 11.

[0073] In this embodiment, a plurality of grooves 25 are evenly distributed axially on the other end of the input transmission member 1 for accommodating the swinging space of the forward transmission member 14 and the reverse transmission member 9, and the forward and reverse transmission member support springs 15 are arranged in the middle part of the plurality of grooves 25; support plates 13 for the forward transmission member 14 and the reverse transmission member 9 are arranged in parallel on both end surfaces of the plurality of grooves 25, and mounting holes coinciding with the swinging centers 28 of the forward transmission member 14 and the reverse transmission member 9 are arranged on the support plates 13, and the forward transmission member 14 and the reverse transmission member 9 are axially staggered by a set distance, and the set distance satisfies the locking and releasing conditions of the reverse transmission member 9.

[0074] Specifically, the axial lengths of the forward transmission member 14 and the reverse transmission member 9 are equal, and the two are staggered by a set distance in the axial direction, and the set distance ensures that the reverse transmission member 9 can be locked and released. The swing centers 28 of the forward transmission member 14 and the reverse transmission member 9 are coaxial and collinear with the axis of the core shaft, and are installed on the support plate 13 at both ends of the multiple grooves 25. Under the action of the supporting torsion spring 15, the two are respectively applied with counterclockwise and clockwise elastic torques on the inner side of the multiple grooves 25, so that the forward transmission member 14 and the reverse transmission member 9 are engaged with the forward conjugate surface 24 and the reverse conjugate surface 23 of the annular structure of the output transmission member 11, respectively realizing the transmission of the forward torque and the reverse torque.

[0075] In this embodiment, the output transmission member 11 is provided with an annular structure, and the annular structure on the output transmission member 11 is coaxially arranged at one end of the multiple grooves 25 of the input transmission member 1, and is sleeved on the multiple grooves 25 of the input transmission member 1. The inner circumference of the annular structure is provided with forward conjugate surfaces 24 and reverse conjugate surfaces 23, the same number as the forward transmission member 14 and the reverse transmission member 9 and evenly distributed.

[0076] Specifically, the annular structure of the output transmission member 11 is coaxial and contains multiple grooves 25, forming a swing space for the reverse transmission member 9 and the forward transmission member 14. When the forward transmission member 14 and the reverse transmission member 9 are supported by the elastic force of the supporting torsion spring 15, they are respectively engaged with the forward conjugate surface 24 and the reverse conjugate surface 23 in the annular structure of the output transmission member 11.

[0077] In this embodiment, the transmission control mechanism 27 includes:

[0078] An actuator, used to switch the transmission mode of the composite controllable overrunning clutch device 26;

[0079] Power source energy supply sensor: used to read the data of the power source energy supply strength;

[0080] Mechanical transmission end brake device sensor: used to read the data of braking force during braking;

[0081] Mechanical transmission running direction sensor: used to determine the running direction of mechanical transmission;

[0082] A speed sensor, used to read the speed data of the input transmission member 1 and the output transmission member 11;

[0083] A speed regulating module, used for regulating the speed of the input transmission member 1;

[0084] The control unit is connected with a power source energy supply sensor, a mechanical transmission end brake device sensor, a mechanical transmission running direction sensor, a speed sensor, a speed control module and an actuator through a data line.

[0085] Specifically, the rotation speed of the input transmission member 1 and the output transmission member 11, the energy supply state of the mechanical transmission power source, the working state of the mechanical transmission terminal brake device, and the running direction of the mechanical transmission are used as the basis for the transmission control mechanism 27 to control the composite controllable overrunning clutch device 26 to switch the transmission mode, which is an implementation mode of the device. When the rotation speed of the output transmission member 11 is greater than the rotation speed of the input transmission member 1, the composite controllable overrunning clutch device switches to the inertia mode, the forward transmission member 14 is disengaged from the forward conjugate surface 24 in the annular structure of the output transmission member 11, and the driving torque is not transmitted, and the inertia transmission mode is entered. At this time, the inertia energy is sufficient to maintain the normal operation of the mechanism on the output transmission member 11, and the inertia energy is fully utilized, reducing the energy consumption of the power source. The control unit can control the composite controllable overrunning clutch device 26 to switch from the rigid transmission mode to the inertial transmission mode, and no longer transmit the driving torque, which not only solves the problem caused by reverse drive, but also can effectively utilize the inertial energy and save energy; when the inertial energy is not enough to maintain the normal operation of the mechanism on the output transmission member 11, that is, when the energy required by the output transmission member 11 is insufficient, the control unit can increase the power source energy supply, increase the speed of the input transmission member 1, so that the speed of the input transmission member 1 is as close as possible to the speed of the output transmission member 11, and avoid the composite controllable overrunning clutch device 26 switching the transmission mode. The speed control module can control the power source energy supply so that the speed of the input transmission member 1 catches up with the speed of the output transmission member 11, and then control the actuator through the control unit to switch the transmission mode of the composite controllable overrunning clutch device 26, switching it from the inertial transmission mode to the rigid transmission mode, and continue to be powered by the power source to ensure the normal operation of the mechanism on the output component. In this way, the inertial energy and the power source energy are alternately utilized to realize the working process of mechanical transmission.

[0086] When the mechanical transmission runs in reverse or needs to be braked to stop, the control unit controls the actuator to switch the transmission mode of the composite controllable overrunning clutch device 26 from the inertial transmission mode to the rigid transmission mode to ensure the safe operation of the mechanical transmission.

[0087] In this embodiment, the actuator includes:

[0088] An input disc 17 is coaxially disposed on the input transmission member 1 and rigidly connected to the input transmission member 1 via a flat key 20. A plurality of through slots 19 are formed on the input disc 17;

[0089] A toggle plate 16 is capable of rotating relative to the input transmission member 1 within a set angle range. A toggle block is disposed on one side of the toggle plate 16, and the toggle block can lock or release the reverse transmission member 9. A plurality of connecting pins are disposed on the other side of the toggle plate 16, and the plurality of connecting pins pass through a plurality of through slots 19 of the input plate 17.

[0090] The tension spring 18 connecting the input disk and the toggle disk is used to make the multiple connecting feet on the toggle disk 16 be at the extreme position I of the through slot 19 in a free state, and make the toggle block on the toggle disk 16 release the reverse transmission member 9; the tension spring 18 connecting the input disk and the toggle disk is used to make the multiple connecting feet be at the extreme position II of the through slot 19 in a stretched state, and make the toggle block on the toggle disk 16 lock the reverse transmission member 9;

[0091] The brake drum 8 is rigidly connected to the dial 16 via a connecting foot passing through the through slot 19 , and a controllable brake mechanism 7 is provided on the outer circumference of the brake drum 8 , and the brake mechanism 7 is associated with the transmission mode of the compound controllable overrunning clutch device 26 .

[0092] Specifically, the input disk 17 is rigidly connected to the input transmission member 11 through a flat key 20, the connecting foot on the toggle disk 16 passes through the through slot 19 on the input disk 17 and is rigidly connected to the brake drum 8 through a screw, the connecting body can rotate around the input transmission member 1, the through slot 19 is a fan-shaped slot, the connecting foot can rotate a set angle in the through slot 19, so that the toggle disk 16 and the brake drum 8 can rotate a set angle relative to the input disk 17 and the input transmission member 1, the tension spring connecting the input disk and the toggle disk The tension spring 18 connects the input disk 17 and the toggle disk 16, and pulls the connecting foot of the toggle disk 16 in a free state, so that the connecting foot of the toggle disk 16 is in the extreme position I of the through slot 19. At the extreme position I, the dial block of the toggle disk 16 releases the reverse transmission member 9, and does not prevent the reverse transmission member 9 from annularly rotating with the output transmission member 11 The reverse conjugate surfaces 23 in the structure are engaged to achieve the transmission of reverse torque. At this time, the compound controllable overrunning clutch device 26 is in a rigid transmission mode; and when the brake drum 8 is braked by the brake mechanism 7 (not shown), due to the rotation of the input transmission member 1, the relative positions of the input disk 17 and the dial plate 16 can be changed, and the connecting foot of the dial plate 16 will be rotated from the extreme position I of the through groove 19 to the extreme position II of the through groove 19. When the connecting foot of the dial plate 16 is in the extreme position II, the dial block of the dial plate 16 will lock the reverse transmission member 9 and press it into the multiple grooves 25 on the input transmission member 1, so that the reverse transmission member 9 is separated from the reverse conjugate surface 23 in the annular structure of the output transmission member. At this time, the compound controllable overrunning clutch device 26 is in an inertia energy-saving operation transmission mode.

[0093] In this embodiment, a transmission mode holding mechanism is further included, one end of which is rigidly connected to the input transmission member 1 , and the other end of which can be controllably engaged or disengaged with the brake drum 8 .

[0094] Specifically, the transmission holding mechanism can limit the relative rotation of the brake drum 8 and the input transmission member 1 to a set angle. If the transmission holding mechanism is engaged with the lock hole of the brake drum 8, the brake drum 8 is fixed relative to the input transmission member 1, and the input disk 17 is fixed on the input transmission member 1, then it is equivalent to that the relative position of the dial 16 and the input disk 17 is fixed, and at this time, the compound controllable overrunning clutch device 26 can be kept in a transmission mode.

[0095] In this embodiment, the transmission mode holding mechanism includes:

[0096] The lock seat 2 is rigidly connected to the input transmission member 1;

[0097] A locking rod 6, one end of which is hinged on the lock base 2, and the other end of which is provided with a lock head;

[0098] A lock hole is provided on the brake drum 8, and the lock hole can be engaged with or disengaged from the lock head;

[0099] The lock rod torsion spring 3 between the lock seat 2 and the lock rod 6 is used to apply torque to the lock rod 6 so that the lock head is locked into the lock hole on the brake drum 8.

[0100] Specifically, the locking hole includes a locking hole A21 and a locking hole B22. The locking rod is in the shape of a plate, namely, a locking plate 5. The locking head on the locking rod 6 is arranged on the side of the locking rod 6 close to the brake drum 8. The locking rod 6 can swing between the electromagnetic sensor 4 and the brake drum 8. As the locking rod 6 swings, the locking head on the locking rod 6 can be inserted into the locking hole A21 and the lock hole B22 and moved out of the locking hole A21 and the lock hole B22. The elastic force of the locking rod torsion spring 3 makes the locking rod 6 always have a tendency to move into the lock hole A21 and the lock hole B22. In the initial transmission mode, the lock head on the lock rod 6 is disengaged from the lock holes A21 and B22. Under the action of the tension spring 18, the toggle plate 16 is in the extreme position I relative to the input transmission member 1, and the compound controllable overrunning clutch device 26 is in the rigid transmission mode. When the brake mechanism 7 on the brake drum 8 is started, the toggle plate 16 and the brake drum 8 are rotated relative to the input transmission member 1. When the lock head on the lock rod 6 is engaged with the lock holes A21 and B22 on the brake drum 8, the brake of the brake mechanism 7 is released, the tension spring 18 is in a stretched state, and the connecting foot of the toggle plate 16 is in the extreme position II. At this time, the compound controllable overrunning clutch device 26 is in the inertia energy-saving operation transmission mode. When the compound controllable overrunning clutch device 26 switches from the inertia energy-saving operation transmission mode to the rigid mode, the electromagnetic sensor 4 is started to suck the lock head on the lock rod 6 out of the lock holes A21 and B22 on the brake drum 8, so that the lock head on the lock rod 6 is separated from the brake drum 8. At this time, the combination of the toggle plate 16 and the brake drum 8 rotates an angle relative to the input transmission member 1 under the action of the tension spring 18, and the effect of the electromagnetic sensor 4 is released, so that the combination of the toggle plate 16 and the brake drum 8 is in the extreme position I, thereby realizing the switching from the inertia energy-saving operation transmission mode to the rigid mode.

[0101] In this embodiment, a driving structure is also included. The driving structure cooperates with the locking rod 6 . The driving structure can drive the locking rod 6 to drive the locking head to disengage from the locking hole of the brake drum 8 .

[0102] Specifically, the driving mechanism is used to drive the lock rod 6 to swing, thereby driving the lock head to move out of the lock holes A21 and B22, thereby releasing the inertia energy-saving operation transmission mode of the composite controllable overrunning clutch device 26.

[0103] In this embodiment, the driving structure includes an electromagnetic inductor 4 , which is arranged on a side of the locking rod 6 away from the brake drum 8 and fixed on the body of the inertial energy-saving device for mechanical transmission. The electromagnetic inductor 4 can adsorb the locking rod 6 .

[0104] In this embodiment, the speed sensor includes a speed sensor 10 of the input transmission member 1 and a speed sensor 12 of the output transmission member 11. The speed sensor 10 of the input transmission member 1 is used to read the speed data of the brake drum 8 when the dial 16 is in the extreme position I or the extreme position II, and the speed sensor 12 of the output transmission member 11 is used to read the speed data of the output transmission member 11.

[0105] Specifically, no matter which transmission mode the compound controllable overrunning clutch device 26 is in and maintained, the relative position of the brake drum 8 and the input transmission member 1 is constant, so the rotation speed of the input transmission member 1 can be obtained by reading the rotation speed of the brake drum 8 .

[0106] In this embodiment, the output transmission member 1 and the input transmission member 11 are processed by the control program in the control unit based on the detection results of the speed sensor, the power source energy supply sensor, the mechanical transmission end brake device sensor, and the mechanical transmission running direction sensor. The control unit then issues instructions to the actuator to complete the switching of different transmission modes through the composite controllable overrunning clutch device 26.

[0107] In this embodiment, a forward and reverse transmission member supporting spring 15 for supporting the forward transmission member 14 and the reverse transmission member 9 is disposed in the middle of the plurality of grooves 25 of the input transmission member 1 .

[0108] Specifically, the forward and reverse transmission member support springs 15 are used to continuously provide elastic support for the forward transmission member 14 and the reverse transmission member 9 .

[0109] In this embodiment, support plates 13 of the forward transmission member 14 and the reverse transmission member 9 are arranged in parallel on both end surfaces of the plurality of grooves 25 of the input transmission member 1 , and the forward transmission member 14 and the reverse transmission member 9 are arranged between the two support plates 13 .

[0110] Specifically, the two support plates 13 and the plurality of grooves 25 on the input transmission member 1 contain the reverse conjugate surface 23 and the forward conjugate surface 24 in the annular structure of the output transmission member, forming a swing space for the forward transmission member 14 and the reverse transmission member 9 .

[0111] In this embodiment, the forward transmission member 14 and the reverse transmission member 9 are evenly distributed at corresponding positions on the forward conjugate surface 24 and the reverse conjugate surface 23, respectively. One end of the forward transmission member 14 and the reverse transmission member 9 are respectively engaged with the forward conjugate surface 24 in the annular structure and controllably engaged with the reverse conjugate surface 23 in the annular structure.

[0112] Specifically, a forward transmission member 14 and a reverse transmission member 9 are disposed in each of the plurality of grooves 25 . The uniform distribution of the plurality of grooves 25 on the periphery of the input transmission member 1 makes the force more balanced and the transmission more stable during the operation of the mechanical transmission.

[0113] In this embodiment, one side of the forward transmission member 14 engages with the forward conjugate surface 24 in the annular structure on the output transmission member 11 during forward driving and disengages during forward overtaking; when the reverse transmission member 9 is in the released state, it engages with the reverse conjugate surface 23 in the annular structure on the output transmission member 11, and at this time, it disengages from the shift block on the dial 16. When the reverse transmission member 9 is in the locked state, it is pressed down by the shift block on the dial 16, and at this time, it disengages from the reverse conjugate surface 23 in the annular structure on the output transmission member 11.

[0114] Specifically, the forward conjugate surface 24 and the reverse conjugate surface 23 are correspondingly engaged or disengaged with only one side surface of the forward transmission member 14 and one side surface of the reverse transmission member 9. When the other side surface of the reverse transmission member 9 is pressed down by the shift block on the shift plate 16 when the compound controllable overrunning clutch device 26 is in the inertia energy-saving operation transmission mode, the compound controllable overrunning clutch device 26 is switched to the inertia energy-saving operation transmission mode.

[0115] In this embodiment, a manual operation module is also included. The manual operation module is associated with the control unit. The manual operation module is used to control the control unit to issue an instruction to change the transmission mode of the composite controllable overtaking device 26.

[0116] Specifically, the setting of the manual operation module can manually intervene in the control of the control unit over the execution module, that is, the control of the transmission mode of the compound controllable overrunning clutch device 26. When a device failure occurs, the manual operation module can be used to control the device in the inertial energy-saving operation transmission mode to enter the rigid transmission mode, thereby ensuring that the mechanical transmission can continue to operate and prepare for maintenance.

[0117] In summary, when the inertial energy-saving device for mechanical transmission provided by the present invention is used, take the rotating mechanical transmission as an example: the input transmission member 1 receives the driving torque transmitted by the power source, and the output transmission member 11 is rigidly connected to the end of the actuator of the mechanical transmission device to complete the working process of the mechanical transmission device. The input transmission member 1 transmits the received driving torque transmitted by the power source to the output transmission member 11 through the composite controllable overrunning clutch device 26 to complete the working process of the mechanical transmission device. The mechanical transmission adopts the composite controllable overrunning clutch device 26, which changes the rigidly connected single transmission mode of mechanical transmission in the traditional sense. In the rigid transmission mode, if the rotation speed of the output transmission member 11 is greater than the rotation speed of the input transmission member 1, reverse drive will be generated. Reverse drive not only requires increasing the load of the power source, but also causes additional mechanical wear and reduces the service life of the mechanical transmission device. The mechanical transmission adopts a composite controllable overrunning clutch device 26, which can realize three transmission modes: the first transmission mode has the same function as the traditional rigid transmission mode; the second transmission mode is a forward transmission mode, which only transmits forward drive torque and does not transmit reverse drive torque, eliminating the reverse drive phenomenon, reducing additional power source consumption and mechanical wear, and increasing the service life of the mechanical transmission device. The third transmission mode is an inertial energy-saving operation transmission mode, which does not transmit torque, and the mechanical transmission device is completely in inertial operation, without the consumption of power source energy and mechanical wear of the transmission parts before the output transmission member 11.

[0118] When the device is used, the input transmission member 1 is first driven to rotate by the power source. At this time, under the action of the forward and reverse transmission member support springs 15, the forward transmission member 14 and the reverse transmission member 9 are respectively meshed with the forward conjugate surface 24 and the reverse conjugate surface 23 in the annular structure of the output transmission member 11, and the composite controllable overrunning clutch device 26 is in a rigid transmission mode, which can transmit forward, reverse and reverse driving torques. Moreover, under the action of the tension spring 18 connecting the input disk and the toggle disk, the connecting foot of the toggle disk 16 is at one end in the through groove 19, that is, the extreme position I, and the lock head on the locking rod 6 is disengaged from the lock holes A21 and B22 on the brake drum 8, and is attached to the brake drum 8 together with the input transmission. The moving member 1 is driven to rotate synchronously. At this time, the dial block on the dial 16 does not contact the reverse transmission member 9. The reverse transmission member 9 is engaged with the reverse conjugate surface 23 in the annular structure of the output transmission member 11, and the torque is transmitted by the composite controllable overrunning clutch device 26 to drive the output transmission member 11 to rotate; at the same time, the speed sensor 10 of the input transmission member 1 and the speed sensor 12 of the output transmission member 11 read the speed data of the input transmission member 1 and the output transmission member 11 respectively. When the composite controllable overrunning clutch device 26 needs to switch the transmission mode, the speed control system is started. When the speed of the output transmission member 11 is close to the speed of the input transmission member 1, the transmission mode is switched.

[0119] The initial transmission mode of the composite controllable overrunning clutch device 26 is the rigid transmission mode. When switching from the rigid transmission mode to the inertia energy-saving operation transmission mode, the braking system 7 is started to apply braking force to the brake drum 8, so that the brake drum 8 rotates relative to the input transmission member 1. The lock head on the lock rod 6 is engaged with the lock hole A21 and the lock hole B22 of the brake drum 8 under the action of the lock rod torsion spring 3, and the braking force of the braking system 7 is released. At this time, the combination of the brake drum 8 and the toggle plate 16 rotates a set angle relative to the input transmission member 1, and the tension spring 18 between the input disk 17 and the toggle plate 16 is stretched. The connecting foot of the toggle plate 16 is in the extreme position II, and the toggle block on the toggle plate 16 overcomes the supporting elastic force of the support spring 15, overwhelms the reverse transmission member 9, locks the reverse transmission member 9, and disengages the reverse conjugate surface 23 in the annular structure of the output transmission member 11, completing the switching of the inertia energy-saving operation transmission mode.

[0120] When switching from the inertial energy-saving operation transmission mode to the rigid transmission mode, the speed control mechanism of the starting control system starts the power source energy supply system to increase energy and starts the braking system of the mechanical transmission device to apply braking force to the output transmission member 11 based on the speed data of the input transmission member sensor 10 and the output transmission member sensor 12 read out, so that the speed of the input transmission member 1 reaches or approaches the speed of the output transmission member 11. When the rotation speed of the input transmission member 1 is close to the rotation speed of the output transmission member 11, the electromagnetic inductor 4 applies an adsorption force to the lock rod 6, and the lock head on the lock rod 6 is sucked out from the lock holes A21 and B22 on the brake drum 8. Under the action of the tension spring 18 connecting the input disk and the toggle disk, the brake drum 8 and the toggle disk 16 rotate a set angle relative to the input transmission member 1, so that the connecting foot on the toggle disk 16 enters the extreme position I. At this time, the reverse transmission member 9 moves out of the lock block on the toggle disk 16, and under the action of the supporting spring 15, one side of the reverse transmission member 9 is elastically engaged with the reverse conjugate surface 23 in the annular structure of the output transmission member 11; at this time, the electromagnetic inductor 4 is withdrawn to release the lock rod 6. Under the action of the lock rod torsion spring 3, the lock head on the lock rod 6 is attached to the brake drum 8 and rotates with the input transmission member 1.

[0121] When the inertia energy-saving operation transmission mode is in operation, the power source can reduce power output or interrupt power output, making full use of inertia to drive the mechanical transmission system to operate, which not only reduces energy consumption but also avoids additional energy consumption caused by reverse drive and wear of transmission parts of the transmission machinery.

[0122] When the inertia is not enough to support the normal operation of the mechanical transmission system, it is necessary to input power through the power source again. At this time, in order to avoid a large speed difference between the input transmission member 1 and the output transmission member 11, which may cause an impact on the mechanical transmission system, the speed sensor 10 of the input transmission member 1 and the speed sensor 12 of the output transmission member 11 transmit data, and the energy supply system of the power source and the braking mechanism of the mechanical transmission system are controlled by the adjustment module, so that the speed of the input transmission member 1 is close to or the same as the speed of the output transmission member 11. At this time, the control unit starts the electromagnetic sensor 4, which attracts the lock rod 6 and releases it. The brake drum 8 and the toggle plate 16 are released. Under the action of the tension spring 18 connecting the input plate and the toggle plate, the toggle plate 16 rotates relative to the input transmission member 1 and the input plate 17. The connecting foot on the toggle plate 16 rotates in the through groove 19 and returns to one end of the through groove 19, that is, the extreme position I. The shift block on the toggle plate 16 releases the reverse transmission member 9. Under the action of the forward and reverse transmission member support springs 15, the reverse transmission member 9 rotates and engages with the reverse conjugate surface 23 in the annular structure of the output transmission member 11, completing the switch from the inertial energy-saving operation transmission mode to the rigid transmission mode. The power source continues to provide power to ensure the normal operation of the mechanical transmission device.

[0123] When the device fails, the device in the inertial energy-saving operation transmission mode can be controlled by the manual operation module to enter the rigid transmission mode, ensuring that the mechanical transmission device can continue to operate and be ready for maintenance.

[0124] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
