Description

Technical Field

[0001] This invention relates to a dual-actuation friction clutch based on inertia and friction, primarily used in the field of transmission technology. Background Technology

[0002] Friction clutches selectively engage various power or motion actions using the friction between their engaging elements. Compared to conventional ratchet clutches, friction clutches typically offer advantages such as compact structure, smooth engagement, and low operating noise. Friction clutches can engage and disengage automatically or with the aid of external actuators. When a friction clutch operates in the disengaged or overrunning state, especially when used as an overrunning clutch, one-way clutch, or one-way brake, the engaging elements wear continuously through mutual contact under the action of springs. This wear is particularly rapid during high-speed operation in the disengaged or overrunning state. Wear of the engaging elements can lead to a decrease in the clutch's engagement performance and even premature failure. Therefore, how to selectively disengage the engaging elements when needed is a pressing technical problem to be solved in the field of friction clutches. Summary of the Invention

[0003] To address the aforementioned technical problems existing in friction wheel clutches, this invention aims to provide a dual-actuation friction clutch based on both inertia and friction. This dual-actuation friction clutch is used to connect at least two components of a machine, device, transmission system, or mechanism, and / or to selectively engage or disengage the power or motion of the connected moving parts using the interaction between the pawl and the friction wheel, and / or to selectively decelerate, stop, or maintain a stopped state of the connected moving parts using the interaction between the pawl and the friction wheel.

[0004] This invention is achieved through the following scheme:

[0005] The inertia-and-friction dual-actuated friction clutch includes: a pawl, a friction wheel, a return spring, a pawl seat, a friction cam, and a release spring. The pawl is mounted on the pawl seat and is rotatable relative to the pawl seat within a certain angle range. Alternatively, the pawl is mounted on the friction cam and is rotatable relative to the friction cam within a certain angle range. The friction cam is mounted on the pawl seat and is rotatable relative to the pawl seat within a certain angle range. One end of the release spring is mounted on the friction cam. Under the rotational inertia of the components of the inertia-and-friction dual-actuated friction clutch, the other end of the release spring selectively contacts or disengages from the friction wheel. The friction cam is connected to the pawl, or the pawl seat is connected to the pawl. The return spring is connected to the pawl. When the release spring is in contact with the friction wheel, the pawl selectively disengages from the friction wheel under the frictional action of the friction wheel. When the release spring is in contact with the friction wheel, the pawl selectively engages and disengages with the friction wheel under its frictional action. The friction wheel and the pawl seat are respectively connected to external components (the external components refer to components excluding those of the "inertia and friction dual-actuated friction clutch").

[0006] Further, the pawl includes a first pawl 1. The friction wheel includes a first friction wheel 2. The return spring includes a first return spring 3. The pawl seat includes a first pawl seat 4. The friction cam includes a first friction cam 5. The release spring includes a first release spring 18. The first pawl 1 is disposed on the first pawl seat 4, and the first pawl 1 is rotatable relative to the first pawl seat 4 within a certain angle range. The first friction cam 5 is disposed on the first pawl seat 4, and the first friction cam 5 is rotatable relative to the first pawl seat 4 between a first limited angle and a third limited angle, and a second limited angle is provided between the first limited angle and the third limited angle. One end of the first release spring 18 is disposed on the first friction cam 5. Under the action of the rotational inertia of the components of the dual-actuated friction clutch, the other end of the first release spring 18 selectively contacts the first friction wheel 2, or selectively disengages from the first friction wheel 2. The first friction cam 5 is connected to the first pawl 1. The first return spring 3 is connected to the first pawl 1. When the absolute value of the angular acceleration or deceleration of the first pawl seat 4 is less than a certain range, and when the first return spring 3 is in contact with the first friction wheel 2, under the frictional action of the first friction wheel 2, the first friction cam 5 can rotate relative to the first pawl seat 4 between the first limited angle and the second limited angle. When the absolute value of the angular acceleration or deceleration of the first pawl seat 4 is greater than a certain range, under the action of the rotational inertia of the components of the dual-actuated friction clutch, the first friction cam 5 can rotate relative to the first pawl seat 4 between the first limited angle and the third limited angle. When the first friction cam 5 rotates relative to the first pawl seat 4 to the first limited angle position, the first pawl 1 and the first friction wheel 2 selectively engage and disengage, and the first release spring 18 contacts the first friction wheel 2. When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, the first pawl 1 disengages from the first friction wheel 2, and the first release spring 18 contacts the first friction wheel 2. When the first friction cam 5 rotates relative to the first pawl seat 4 to the third defined angle position, the first pawl 1 disengages from the first friction wheel 2, and the first release spring 18 disengages from the first friction wheel 2. The first friction wheel 2 and the first pawl seat 4 are respectively connected to the external components.

[0007] Alternatively, the pawl includes a first pawl 1. The friction wheel includes a first friction wheel 2. The return spring includes a first return spring 3. The pawl seat includes a first pawl seat 4. The friction cam includes a first friction cam 5. The release spring includes a first release spring 18. The first pawl 1 is disposed on the first friction cam 5, and the first pawl 1 is rotatable relative to the first friction cam 5 within a certain angle range. The first friction cam 5 is disposed on the first pawl seat 4, and the first friction cam 5 is rotatable relative to the first pawl seat 4 between a first limited angle and a third limited angle, and a second limited angle is provided between the first limited angle and the third limited angle. One end of the first release spring 18 is disposed on the first friction cam 5, and under the action of the rotational inertia of the components of the dual-actuated friction clutch, the other end of the first release spring 18 selectively contacts the first friction wheel 2, or selectively disengages from the first friction wheel 2. The first pawl seat 4 is connected to the first pawl 1. The first return spring 3 is connected to the first pawl 1. When the absolute value of the angular acceleration or deceleration of the first pawl seat 4 is less than a certain range, and when the first return spring 3 is in contact with the first friction wheel 2, under the frictional action of the first friction wheel 2, the first friction cam 5 can rotate relative to the first pawl seat 4 between the first limited angle and the second limited angle. When the absolute value of the angular acceleration or deceleration of the first pawl seat 4 is greater than a certain range, under the action of the rotational inertia of the components of the dual-actuated friction clutch, the first friction cam 5 can rotate relative to the first pawl seat 4 between the first limited angle and the third limited angle. When the first friction cam 5 rotates relative to the first pawl seat 4 to the first limited angle position, the first pawl 1 and the first friction wheel 2 selectively engage and disengage, and the first release spring 18 contacts the first friction wheel 2. When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, the first pawl 1 disengages from the first friction wheel 2, and the first release spring 18 contacts the first friction wheel 2. When the first friction cam 5 rotates relative to the first pawl seat 4 to the third defined angle position, the first pawl 1 disengages from the first friction wheel 2, and the first release spring 18 disengages from the first friction wheel 2. The first friction wheel 2 and the first pawl seat 4 are respectively connected to the external components.

[0008] Furthermore, when the friction cam rotates relative to the ratchet seat to the first defined angular position, the friction cam and the ratchet seat have an angular positioning function. When the friction cam rotates relative to the ratchet seat to the second defined angular position, the friction cam and the ratchet seat have an angular positioning function. When the friction cam rotates relative to the ratchet seat to the third defined angular position, the friction cam and the ratchet seat have an angular positioning function.

[0009] Alternatively, when the friction cam rotates relative to the pawl seat to the first defined angle position, the friction cam and the pawl seat achieve an angle positioning function through a series of bosses and grooves. When the friction cam rotates relative to the pawl seat to the second defined angle position, the friction cam and the pawl seat achieve an angle positioning function through a series of bosses and grooves. When the friction cam rotates relative to the pawl seat to the third defined angle position, the friction cam and the pawl seat achieve an angle positioning function through a series of bosses and grooves.

[0010] Alternatively, the inertia and friction dual-actuated friction clutch includes a positioning mechanism 8. When the friction cam rotates relative to the pawl seat to the first defined angle position, the friction cam and the pawl seat are positioned at an angle via the positioning mechanism 8. When the friction cam rotates relative to the pawl seat to the second defined angle position, the friction cam and the pawl seat are positioned at an angle via the positioning mechanism 8. When the friction cam rotates relative to the pawl seat to the third defined angle position, the friction cam and the pawl seat are positioned at an angle via the positioning mechanism 8.

[0011] Furthermore, the friction cam is mounted on the ratchet seat via a bearing. The friction wheel is connected to the ratchet seat via a bearing.

[0012] Further, the first separation spring 18 includes a first separation spring bracket 181 and a first separation spring friction pad 182. The first separation spring bracket 181 has at least a certain elastic deformation capacity. One end of the first separation spring bracket 181 is fixed to the first friction cam 5, and the other end of the first separation spring bracket 181 is fixedly connected to the first separation spring friction pad 182. Alternatively, one end of the first separation spring bracket 181 is fixed to the first friction wheel 2, and the other end of the first separation spring bracket 181 is fixedly connected to the first separation spring friction pad 182. The first separation spring friction pad 182 is in contact with the first friction wheel 2, or the first separation spring friction pad 182 is in contact with the first friction cam 5.

[0013] Compared with existing technologies, the inertia-and-friction dual-actuated friction clutch of the present invention can reduce pawl wear and has higher transmission efficiency. The inertia-and-friction dual-actuated friction clutch of the present invention can selectively disengage the pawl from the friction wheel using the friction between the release spring and the friction wheel, thereby reducing pawl wear. Furthermore, under the action of rotational inertia, the release spring and the friction wheel selectively disengage, and since frictional contact is avoided, the transmission efficiency of the clutch in the disengaged state can be improved.

[0014] The above-mentioned features and advantages of the invention, as well as other features and advantages, will become readily apparent from the following detailed description of the best mode for carrying out the invention, taken in conjunction with the accompanying drawings. However, it should be clearly understood that all the drawings are for illustrative purposes only and not for any limitation on the definition and scope of the invention. Attached Figure Description

[0020] Example 1

[0021] Dual-actuation friction clutch based on inertia and friction, such as Figures 1-10 As shown, the assembly includes a first pawl 1, a first friction wheel 2, a first return spring 3, a first pawl seat 4, a first friction cam 5, a first release spring 18, a first rivet 31, and a second rivet 32. The first release spring 18 includes a first release spring bracket 181 and a first release spring friction pad 182. The first release spring bracket 181 has a large elastic deformation capacity. One end of the first release spring bracket 181 is mounted on the first friction cam 5 via the first rivet 31. The other end of the first release spring bracket 181 is fixedly connected to the first release spring friction pad 182 via the second rivet 32. Thus, the first release spring bracket 181 and the first release spring friction pad 182 are connected to each other as a whole (i.e., the first release spring 18). The first release spring friction pad 182 is in contact with or out of contact with the first friction wheel 2. Therefore, overall, the first release spring 18 and the first friction wheel 2 are in contact or out of contact.

[0022] The first pawl seat 4 includes a first pawl seat bracket 41, a first pawl seat rivet 47, and a first pawl center seat 49. Under the action of the first pawl seat rivet 47, the first pawl seat bracket 41, the first pawl seat rivet 47, and the first pawl center seat 49 are connected to each other to form a whole (i.e., the first pawl seat 4).

[0023] The first friction cam 5 is provided with a first positioning boss 9, and the first pawl seat 49 is provided with a first positioning groove 10, a second positioning groove 11, and a third positioning groove 12. The number of the first positioning boss 9, the first positioning groove 10, the second positioning groove 11, and the third positioning groove 12 can be set according to the actual working conditions.

[0024] The first friction wheel 2 and the first friction cam 5 are both arranged coaxially with the first pawl seat 4. The first friction wheel 2 and the first pawl seat 4 are respectively connected to external components (not shown, the external components refer to components excluding the "components of the inertia and friction dual-actuated friction clutch") via splines.

[0025] The first pawl 1 is mounted on the first pawl seat 4 via a clearance fit through a shaft hole. The first pawl 1 is rotatable relative to the first pawl seat 4 and is axially fixed relative to the first pawl seat 4 by riveting bosses at both ends. The radial groove 29 of the first friction cam 5 is connected to the first pawl 1. The first return spring 3 is connected to the first pawl 1. The first pawl seat 4 interacts with the first pawl 1 through the first return spring 3 and the clearance fit through the shaft hole.

[0026] Preferably, the first friction cam 5 is rotatably mounted on the first pawl seat 4 via a clearance fit through a shaft hole. Optionally, the first friction cam 5 can also be mounted on the first pawl seat 4 via a rolling bearing or a sliding bearing. Under the action of the first pawl 1, the first friction cam 5 is fixed axially relative to the first pawl seat 4. The radial protrusion 19 of the first friction cam 5 engages with the radial groove 27 of the first pawl seat 49, thereby allowing the first friction cam 5 to rotate relative to the first pawl seat 4 between a first defined angle and a third defined angle. A second defined angle is provided between the first defined angle and the third defined angle. Between the second defined angle and the third defined angle, the separation boss 24 of the first pawl seat bracket 41 has a certain limiting effect on the first separation spring 18. Therefore, when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, and when the first separation spring 18 is in contact with the first friction wheel 2, the first friction cam 5 can rotate relative to the first pawl seat 4 between the first limited angle and the second limited angle under the friction action of the first friction wheel 2; when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is greater than a certain range, under the action of the rotational inertia of the first friction cam 5, the first separation spring 18, the first rivet 31, and the second rivet 32, the first separation spring 18 and the first friction cam 5 overcome the limiting effect of the separation boss 24 of the first pawl seat bracket 41 and overcome the action of various frictional torques, thereby allowing the first friction cam 5 to rotate relative to the first pawl seat 4 between the first limited angle and the third limited angle.

[0027] When the first friction cam 5 rotates relative to the first pawl seat 4 to the first defined angle position, under the action of the first return spring 3 and the first friction cam 5, the first pawl 1 and the first friction wheel 2 can be engaged or disengaged, and the first separation spring 18 interacts with the first friction wheel 2 through friction. At this time, through the first pawl 1, the first pawl seat 4 can selectively transmit the power or movement of the first pawl seat 4 to the first friction wheel 2. Alternatively, through the first pawl 1, the first friction wheel 2 can selectively transmit the power or movement of the first friction wheel 2 to the first pawl seat 4.

[0028] Furthermore, when the first friction cam 5 is at the first defined angle position relative to the first pawl seat 4, the first pawl seat 4 provides a certain angular positioning function for the first friction cam 5 through the interaction between the first positioning boss 9 and the first positioning groove 10. At this time, even with external interference or power impact, the first friction cam 5 remains at the first defined angle position relative to the first pawl seat 4. Therefore, through the interaction between the first positioning boss 9 and the first positioning groove 10, the inertia and friction dual-actuated friction clutch has a certain shifting reliability and stability at the first defined angle position.

[0029] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, under the action of the first return spring 3 and the first friction cam 5, the first pawl 1 disengages from the first friction wheel 2, and the first separation spring 18 interacts with the first friction wheel 2 through friction.

[0030] Similarly, when the first friction cam 5 is at the second defined angle position relative to the first pawl seat 4, the first pawl seat 4 provides a certain angular positioning function for the first friction cam 5 through the interaction between the first positioning boss 9 and the second positioning groove 11. At this time, even with external interference or power impact, the first friction cam 5 remains at the second defined angle position relative to the first pawl seat 4. Therefore, through the interaction between the first positioning boss 9 and the second positioning groove 11, the inertia and friction dual-actuated friction clutch has a certain shifting reliability and stability at the second defined angle position.

[0031] When the first friction cam 5 rotates relative to the first pawl seat 4 to the third defined angle position, under the action of the first return spring 3 and the first friction cam 5, the first pawl 1 disengages from the first friction wheel 2, and under the action of the separation boss 23 of the first pawl seat 4, the first separation spring 18 disengages from the first friction wheel 2.

[0032] Similarly, when the first friction cam 5 is at the third defined angle position relative to the first pawl seat 4, the first pawl seat 4 provides a certain angular positioning function for the first friction cam 5 through the interaction between the first positioning boss 9 and the third positioning groove 12. At this time, even with external interference or power impact, the first friction cam 5 remains at the third defined angle position relative to the first pawl seat 4. Therefore, through the interaction between the first positioning boss 9 and the third positioning groove 12, the inertia and friction dual-actuated friction clutch has a certain degree of shifting reliability and stability at the third defined angle position.

[0033] Preferably, in the initial state, the first friction cam 5 is positioned at the first defined angle relative to the first pawl seat 4, the first pawl 1 interacts with the first friction wheel 2 through friction, and the first separation spring 18 interacts with the first friction wheel 2 through friction, such as... Figures 5-6 As shown. At this time, in the reverse direction (opposite to the rotation direction indicated by the arrow in the figure), the first friction wheel 2 is fixed relative to the first pawl seat 4. When the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, and when the first friction wheel 2 rotates clockwise relative to the first pawl seat 4 (rotation direction indicated by the arrow in the figure), under the friction action of the first friction wheel 2, the first separation spring 18 drives the first friction cam 5 to rotate, and thus the first friction cam 5 can rotate relative to the first pawl seat 4 to the second limited angle position. When the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is greater than a certain range, under the rotational inertia of the first friction cam 5, the first separation spring 18, the first rivet 31, and the second rivet 32, the first separation spring 18 and the first friction cam 5 overcome the limiting effect of the separation boss 24 of the first pawl seat bracket 41, overcome the positioning effect of the first positioning boss 9 and the first positioning groove 10, and overcome the effect of various frictional torques, so that the first friction cam 5 can rotate relative to the first pawl seat 4 to the third limited angle position.

[0034] like Figures 7-8As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, the first pawl 1 disengages from the first friction wheel 2, and the first release spring 18 interacts with the first friction wheel 2 through friction. At this time, when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, the first friction wheel 2 can rotate relative to the first pawl seat 4 in the forward rotation direction (the rotation direction indicated by the arrow in the figure). When the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, and when the first friction wheel 2 rotates relative to the first pawl seat 4 in the reverse direction (opposite to the rotation direction indicated by the arrow in the figure), under the frictional action of the first friction wheel 2, the first release spring 18 drives the first friction cam 5 to rotate, and thus the first friction cam 5 can rotate relative to the first pawl seat 4 to the first limited angle position. When the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is greater than a certain range, under the rotational inertia of the first friction cam 5, the first separation spring 18, the first rivet 31, and the second rivet 32, the first separation spring 18 and the first friction cam 5 overcome the limiting effect of the separation boss 24 of the first pawl seat bracket 41, overcome the positioning effect of the first positioning boss 9 and the second positioning groove 11, and overcome the effect of various frictional torques, so that the first friction cam 5 can rotate relative to the first pawl seat 4 to the third limited angle position.

[0035] like Figures 9-10 As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the third defined angle position, the first pawl 1 disengages from the first friction wheel 2, and the first release spring 18 disengages from the first friction wheel 2. At this time, when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, the first friction wheel 2 can rotate relative to the first pawl seat 4 in both forward and reverse directions. At this time, when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is greater than a certain range, under the rotational inertia of the first friction cam 5, the first release spring 18, the first rivet 31, and the second rivet 32, the first release spring 18 and the first friction cam 5 overcome the limiting effect of the release boss 24 of the first pawl seat bracket 41, overcome the positioning effect of the first positioning boss 9 and the third positioning groove 12, and overcome the effect of various frictional torques, thereby allowing the first friction cam 5 to rotate relative to the first pawl seat 4 to the second defined angle position or the first defined angle position.

[0036] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, and when the first friction wheel 2 rotates clockwise relative to the first pawl seat 4, the first pawl 1 disengages from the first friction wheel 2, thereby avoiding contact friction between the pawl and the friction wheel.

[0037] When the first friction cam 5 rotates relative to the first pawl seat 4 to the third defined angle position, and when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, the first pawl 1 disengages from the first friction wheel 2, and the first friction wheel 2 disengages from the first separation spring 18. At this time, not only is contact friction between the pawl and the friction wheel avoided, but contact friction between the first separation spring 18 and the first friction wheel 2 is also avoided.

[0038] When the first release spring 18 and the first friction wheel 2 interact through friction, some wear is inevitable after prolonged operation. However, because the first release spring 18 has a large elastic deformation capacity, the contact pressure between the first release spring 18 and the first friction wheel 2 can be stably maintained within a certain range within a certain service life. Furthermore, it can compensate for some wear between the first release spring 18 and the first friction wheel 2, thereby ensuring stable friction between the first release spring 18 and the first friction wheel 2 within a certain service life.

[0039] Example 2

[0040] Dual-actuation friction clutch based on inertia and friction, such as Figures 11-21 As shown, it includes a first pawl 1, a first friction wheel 2, a first return spring 3, a first pawl seat 4, a first friction cam 5, a positioning mechanism 8, a first separation spring 18, a first rivet 31, and a second rivet 32.

[0041] The first separation spring 18 includes a first separation spring bracket 181 and a first separation spring friction pad 182. The first separation spring bracket 181 has a large elastic deformation capacity. One end of the first separation spring bracket 181 is mounted on the first friction cam 5 via the first rivet 31. The other end of the first separation spring bracket 181 is fixedly connected to the first separation spring friction pad 182 via the second rivet 32. Thus, the first separation spring bracket 181 and the first separation spring friction pad 182 are connected to each other to form a whole (i.e., the first separation spring 18). The first separation spring friction pad 182 is in contact with or out of contact with the first friction wheel 2. Therefore, overall, the first separation spring 18 is in contact with or out of contact with the first friction wheel 2.

[0042] The first friction cam 5 includes a first cam support 51 and a second cam support 52. Under the action of the first pawl 1, the first cam support 51 and the second cam support 52 are connected to each other to form a whole (i.e., the first friction cam 5).

[0043] The first pawl seat 4 includes a first pawl seat bracket 41, a second pawl seat bracket 42, a first pawl seat rivet 47, and a first pawl center seat 49. Under the action of the first pawl seat rivet 47, the first pawl seat bracket 41, the second pawl seat bracket 42, the first pawl seat rivet 47, and the first pawl center seat 49 are connected to each other to form a whole (i.e., the first pawl seat 4).

[0044] The first pawl seat 49 is provided with a first positioning groove 10, a second positioning groove 11, and a third positioning groove 12. The number of the positioning mechanism 8, the first positioning groove 10, the second positioning groove 11, and the third positioning groove 12 can be set according to the actual working conditions.

[0045] The positioning mechanism 8 is fixed to the second cam support 52 via an interference fit through a shaft hole. Preferably, the structure of the positioning mechanism 8 is as follows: Figure 15 As shown.

[0046] The first friction wheel 2 and the first friction cam 5 are both arranged coaxially with the first pawl seat 4. The first friction wheel 2 and the first pawl seat 4 are respectively connected to external components (not shown, the external components refer to components excluding the "components of the inertia and friction dual-actuated friction clutch") via splines.

[0047] The first pawl 1 is mounted on the first friction cam 5 via a clearance fit through a shaft hole. The first pawl 1 is rotatable relative to the first friction cam 5 and is axially fixed relative to the first friction cam 5 by riveted bosses at both ends. The first pawl 1 is connected to the first pawl seat 4 via a contact. The first return spring 3 is connected to the first pawl 1. The first friction cam 5 interacts with the first pawl 1 through the first return spring 3 and the clearance fit through the shaft hole.

[0048] Preferably, the first friction cam 5 and the first pawl seat 4 are fitted with a clearance fit through a shaft hole, thereby allowing the first friction cam 5 to be rotatably mounted on the first pawl seat 4. Optionally, the first friction cam 5 can also be mounted on the first pawl seat 4 via a rolling bearing or a sliding bearing. Under the action of the first pawl 1, the first friction cam 5 is fixed axially relative to the first pawl seat 4. The radial protrusion 22 of the first cam support 51 engages with the radial groove 27 of the first pawl seat 49, thereby allowing the first friction cam 5 to rotate relative to the first pawl seat 4 between a first defined angle and a third defined angle. A second defined angle is provided between the first defined angle and the third defined angle. Between the second defined angle and the third defined angle, the separation boss 24 of the first pawl seat support 41 and the separation boss 25 of the second pawl seat support 42 have a certain limiting effect on the first separation spring 18. Therefore, when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, and when the first separation spring 18 is in contact with the first friction wheel 2, under the friction of the first friction wheel 2, the first friction cam 5 can rotate relative to the first pawl seat 4 between the first limited angle and the second limited angle; when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is greater than a certain range, under the action of the rotational inertia of the first friction cam 5, the first separation spring 18, the first rivet 31, the second rivet 32, the first pawl 1, the first return spring 3, and the positioning mechanism 8, the first separation spring 18 and the first friction cam 5 overcome the limiting effect of the separation boss 24 of the first pawl seat bracket 41 and the separation boss 25 of the second pawl seat bracket 42, and overcome the effect of various frictional torques, thereby allowing the first friction cam 5 to rotate relative to the first pawl seat 4 between the first limited angle and the third limited angle.

[0049] When the first friction cam 5 rotates relative to the first pawl seat 4 to the first defined angle position, under the action of the first return spring 3 and the first pawl seat 4, the first pawl 1 and the first friction wheel 2 can be engaged or disengaged, and the first separation spring 18 interacts with the first friction wheel 2 through friction. At this time, through the first pawl 1, the first pawl seat 4 can selectively transmit the power or movement of the first pawl seat 4 to the first friction wheel 2. Alternatively, through the first pawl 1, the first friction wheel 2 can selectively transmit the power or movement of the first friction wheel 2 to the first pawl seat 4.

[0050] Furthermore, when the first friction cam 5 is at the first defined angle position relative to the first pawl seat 4, the first pawl seat 4 provides a certain angular positioning function for the first friction cam 5 through the interaction between the positioning mechanism 8 and the first positioning groove 10. At this time, even with external interference or power impact, the first friction cam 5 remains at the first defined angle position relative to the first pawl seat 4. Therefore, through the interaction between the positioning mechanism 8 and the first positioning groove 10, the inertia and friction dual-actuated friction clutch has a certain degree of shifting reliability and stability at the first defined angle position.

[0051] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, under the action of the first return spring 3 and the first pawl seat 4, the first pawl 1 disengages from the first friction wheel 2, and the first separation spring 18 interacts with the first friction wheel 2 through friction.

[0052] Similarly, when the first friction cam 5 is at the second defined angle position relative to the first pawl seat 4, the first pawl seat 4 provides a certain angular positioning function for the first friction cam 5 through the interaction between the positioning mechanism 8 and the second positioning groove 11. At this time, even with external interference or power impact, the first friction cam 5 remains at the second defined angle position relative to the first pawl seat 4. Therefore, through the interaction between the positioning mechanism 8 and the second positioning groove 11, the inertia and friction dual-actuated friction clutch has a certain degree of shifting reliability and stability at the second defined angle position.

[0053] When the first friction cam 5 rotates relative to the first pawl seat 4 to the third defined angle position, under the action of the first return spring 3 and the first pawl seat 4, the first pawl 1 disengages from the first friction wheel 2. Under the action of the separation boss 24 of the first pawl seat bracket 41 and the separation boss 25 of the second pawl seat bracket 42, the first separation spring 18 disengages from the first friction wheel 2.

[0054] Similarly, when the first friction cam 5 is at the third defined angle position relative to the first pawl seat 4, the first pawl seat 4 provides a certain angular positioning function for the first friction cam 5 through the interaction between the positioning mechanism 8 and the third positioning groove 12. At this time, even with external interference or power impact, the first friction cam 5 remains at the third defined angle position relative to the first pawl seat 4. Therefore, through the interaction between the positioning mechanism 8 and the third positioning groove 12, the inertia and friction dual-actuated friction clutch has a certain degree of shifting reliability and stability at the third defined angle position.

[0055] Preferably, in the initial state, the first friction cam 5 is positioned at the first defined angle relative to the first pawl seat 4, the first pawl 1 interacts with the first friction wheel 2 through friction, and the first separation spring 18 interacts with the first friction wheel 2 through friction, such as... Figures 16-17 As shown. At this time, in the reverse direction (opposite to the rotation direction indicated by the arrow in the figure), the first friction wheel 2 is fixed relative to the first pawl seat 4. When the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, and when the first friction wheel 2 rotates clockwise relative to the first pawl seat 4 (rotation direction indicated by the arrow in the figure), under the friction action of the first friction wheel 2, the first separation spring 18 drives the first friction cam 5 to rotate, and thus the first friction cam 5 can rotate relative to the first pawl seat 4 to the second limited angle position. When the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is greater than a certain range, under the rotational inertia of the first friction cam 5, the first separation spring 18, the first rivet 31, the second rivet 32, the first pawl 1, the first return spring 3, and the positioning mechanism 8, the first separation spring 18 and the first friction cam 5 overcome the limiting effect of the separation boss 24 of the first pawl seat bracket 41 and the separation boss 25 of the second pawl seat bracket 42, and overcome the positioning effect of the positioning mechanism 8 and the first positioning groove 10, and overcome the effect of various frictional torques, so that the first friction cam 5 can rotate relative to the first pawl seat 4 to the third limited angle position.

[0056] like Figures 18-19 As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, the first pawl 1 disengages from the first friction wheel 2, and the first release spring 18 interacts with the first friction wheel 2 through friction. At this time, when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, the first friction wheel 2 can rotate relative to the first pawl seat 4 in the forward rotation direction (the rotation direction indicated by the arrow in the figure). When the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, and when the first friction wheel 2 rotates relative to the first pawl seat 4 in the reverse direction (opposite to the rotation direction indicated by the arrow in the figure), under the frictional action of the first friction wheel 2, the first release spring 18 drives the first friction cam 5 to rotate, and thus the first friction cam 5 can rotate relative to the first pawl seat 4 to the first limited angle position. When the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is greater than a certain range, under the rotational inertia of the first friction cam 5, the first separation spring 18, the first rivet 31, the second rivet 32, the first pawl 1, the first return spring 3, and the positioning mechanism 8, the first separation spring 18 and the first friction cam 5 overcome the limiting effect of the separation boss 24 of the first pawl seat bracket 41 and the separation boss 25 of the second pawl seat bracket 42, and overcome the positioning effect of the positioning mechanism 8 and the second positioning groove 11, and overcome the effect of various frictional torques, so that the first friction cam 5 can rotate relative to the first pawl seat 4 to the third limited angle position.

[0057] like Figures 20-21As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the third defined angle position, the first pawl 1 disengages from the first friction wheel 2, and the first separation spring 18 disengages from the first friction wheel 2. At this time, when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, the first friction wheel 2 can rotate relative to the first pawl seat 4 in both the forward and reverse directions. At this time, when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is greater than a certain range, under the rotational inertia of the first friction cam 5, the first separation spring 18, the first rivet 31, the second rivet 32, the first pawl 1, the first return spring 3, and the positioning mechanism 8, the first separation spring 18 and the first friction cam 5 overcome the limiting effect of the separation boss 24 of the first pawl seat bracket 41 and the separation boss 25 of the second pawl seat bracket 42, and overcome the positioning effect of the positioning mechanism 8 and the third positioning groove 12, and overcome the effect of various frictional torques, so that the first friction cam 5 can rotate relative to the first pawl seat 4 to the second limited angle position or the first limited angle position.

[0058] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, and when the first friction wheel 2 rotates clockwise relative to the first pawl seat 4, the first pawl 1 disengages from the first friction wheel 2, thereby avoiding contact friction between the pawl and the friction wheel.

[0059] When the first friction cam 5 rotates relative to the first pawl seat 4 to the third defined angle position, and when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, the first pawl 1 disengages from the first friction wheel 2, and the first friction wheel 2 disengages from the first separation spring 18. At this time, not only is contact friction between the pawl and the friction wheel avoided, but contact friction between the first separation spring 18 and the first friction wheel 2 is also avoided.

[0060] When the first release spring 18 and the first friction wheel 2 interact through friction, some wear is inevitable after prolonged operation. However, because the first release spring 18 has a large elastic deformation capacity, the contact pressure between the first release spring 18 and the first friction wheel 2 can be stably maintained within a certain range within a certain service life. Furthermore, it can compensate for some wear between the first release spring 18 and the first friction wheel 2, thereby ensuring stable friction between the first release spring 18 and the first friction wheel 2 within a certain service life.

[0061] Example 3

[0062] Dual-actuation friction clutch based on inertia and friction, such as Figures 22-32 As shown, the assembly includes a first pawl 1, a first friction wheel 2, a first return spring 3, a first pawl seat 4, a first friction cam 5, a first release spring 18, a first rivet 31, and a second rivet 32. The first release spring 18 includes a first release spring bracket 181 and a first release spring friction pad 182. The first release spring bracket 181 has a large elastic deformation capacity. One end of the first release spring bracket 181 is mounted on the first friction cam 5 via the first rivet 31. The other end of the first release spring bracket 181 is fixedly connected to the first release spring friction pad 182 via the second rivet 32. Thus, the first release spring bracket 181 and the first release spring friction pad 182 are connected to each other as a whole (i.e., the first release spring 18). The first release spring friction pad 182 is in contact with or out of contact with the first friction wheel 2. Therefore, overall, the first release spring 18 and the first friction wheel 2 are in contact or out of contact.

[0063] The first pawl seat 4 includes a first pawl seat bracket 41, a first pawl seat bolt 46, and a first pawl center seat 49. Under the action of the first pawl seat bolt 46, the first pawl seat bracket 41, the first pawl seat bolt 46, and the first pawl center seat 49 are connected to each other to form a whole (i.e., the first pawl seat 4).

[0064] The first friction cam 5 is provided with a first positioning boss 9, and the first pawl seat 49 is provided with a first positioning groove 10, a second positioning groove 11, and a third positioning groove 12. The number of the first positioning boss 9, the first positioning groove 10, the second positioning groove 11, and the third positioning groove 12 can be set according to the actual working conditions.

[0065] The first friction wheel 2 and the first friction cam 5 are both arranged coaxially with the first pawl seat 4. The first friction wheel 2 and the first pawl seat 4 are respectively connected to external components (not shown, the external components refer to components excluding the "components of the inertia and friction dual-actuated friction clutch") via splines.

[0066] The first pawl 1 is mounted on the first pawl seat 4 via a clearance fit through a shaft hole. The first pawl 1 is rotatable relative to the first pawl seat 4 and is radially fixed relative to the first pawl seat 4 via a riveting boss. The first pawl 1 is connected to the first friction cam 5 via contact. The first return spring 3 is connected to the first pawl 1. The first pawl seat 4 interacts with the first pawl 1 via the first return spring 3 and the clearance fit through the shaft hole.

[0067] Preferably, the first friction cam 5 is rotatably mounted on the first pawl seat 4 via a clearance fit through a shaft hole. Optionally, the first friction cam 5 may also be mounted on the first pawl seat 4 via a rolling bearing or a sliding bearing. Under the action of the first pawl 1, the first friction cam 5 is fixed axially relative to the first pawl seat 4.

[0068] The radial protrusion 19 of the first friction cam 5 engages with the axial boss 21 of the first pawl seat 49, thereby allowing the first friction cam 5 to rotate relative to the first pawl seat 4 between a first limited angle and a third limited angle. A second limited angle is provided between the first limited angle and the third limited angle. Between the second limited angle and the third limited angle, the separation boss 24 of the first pawl seat bracket 41 has a certain limiting effect on the first separation spring 18. Therefore, when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is less than a certain range, and when the first separation spring 18 is in contact with the first friction wheel 2, the first friction cam 5 can rotate relative to the first pawl seat 4 between the first limited angle and the second limited angle under the friction action of the first friction wheel 2; when the absolute value of the angular acceleration or angular deceleration of the first pawl seat 4 is greater than a certain range, under the action of the rotational inertia of the first friction cam 5, the first separation spring 18, the first rivet 31, and the second rivet 32, the first separation spring 18 and the first friction cam 5 overcome the limiting effect of the separation boss 24 of the first pawl seat bracket 41 and overcome the action of various frictional torques, thereby allowing the first friction cam 5 to rotate relative to the first pawl seat 4 between the first limited angle and the third limited angle.

[0069] The rest is similar to Example 1.
