The clutch at least comprises a pawl, a friction wheel, a return spring, a pawl seat, a friction cam, a release spring and an inertia cam. Under the action of rotation inertia, the separation spring is selectively contacted with the friction wheel, or the separation spring is selectively separated from the friction wheel, or the separation spring is selectively contacted with the friction cam, or the separation spring is selectively separated from the friction cam; and under the friction action of the separation spring or the friction wheel, the pawl and the friction wheel selectively realize separation and reunion, and the pawl and the friction wheel selectively realize contact separation. Compared with the prior art, the clutch can reduce abrasion of the pawls and has high transmission efficiency.

Description

Technical Field

[0001] This invention relates to a friction-actuated friction clutch with an inertial cam, 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 clutches, this invention aims to provide a friction-actuated friction clutch equipped with an inertia cam. The friction-actuated friction clutch with an inertia cam is used to connect at least two components of a machine, device, transmission system, or mechanism, and / or selectively engage or disengage the power or motion of the connected moving parts using the interaction between a pawl and a friction wheel, and / or selectively decelerate, stop, or maintain a stopped state of the connected moving parts using the interaction between the pawl and the friction wheel.

[0023] Example 1

[0024] Friction-actuated friction clutches with inertial cams, such as Figures 1-8 As shown in 45, 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 rivet 15, a second rivet 16, a first separation spring 18, a third rivet 19, and a first inertial cam 30.

[0025] The first separation spring 18 includes a first separation spring bracket 31 and a first separation spring friction pad 32. The first separation spring bracket 31 has a large elastic deformation capacity. One end of the first separation spring bracket 31 is mounted on the first friction cam 5 via the first rivet 15. The other end of the first separation spring bracket 31 is fixedly connected to the first separation spring friction pad 32 via the second rivet 16. Thus, the first separation spring bracket 31 and the first separation spring friction pad 32 are connected to each other to form a whole (i.e., the first separation spring 18). The first separation spring friction pad 32 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.

[0026] The axial groove 26 of the first inertial cam 30 engages with the third rivet 19, thereby allowing the first inertial cam 30 to rotate relative to the first pawl seat 4 between a third and a fourth defined angle. Optionally, the first inertial cam 30 may also be mounted on the first pawl seat 4 via a rolling bearing or a sliding bearing. Furthermore, under the action of the third rivet 19, the first inertial cam 30 is axially fixed relative to the first pawl seat 4.

[0027] The positioning mechanism 8 is mounted on the first friction cam 5 via an interference fit through a shaft hole. Preferably, the structure of the positioning mechanism 8 is as follows: Figure 45 As shown.

[0028] The first inertial cam 30 has a first positioning boss 9 and a second positioning boss 17 in its axial groove 26. The first pawl seat 4 has a first positioning groove 10 and a second positioning groove 11. The number of the positioning mechanism 8, the first positioning boss 9, the first positioning groove 10, the second positioning groove 11, the second positioning boss 17, and the third rivet 19 can be set according to actual working conditions.

[0029] The first friction wheel 2, the first friction cam 5, and the first inertia cam 30 are all coaxially arranged 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 friction-actuated friction clutch with inertia cam") via splines.

[0030] 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 riveted bosses at both ends. The radial groove 6 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.

[0031] 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 23 of the first friction cam 5 engages with the radial groove 21 of the first pawl seat 4, thereby allowing the first friction cam 5 to rotate relative to the first pawl seat 4 between a first defined angle and a second defined angle. When the first separation spring friction pad 32 is in contact with the first friction wheel 2, under the elastic action of the first separation spring bracket 31, the first separation spring friction pad 32 and the first friction wheel 2 interact through friction, that is, the first separation spring 18 and the first friction wheel 2 interact through friction, and the first friction cam 5 interacts with the first friction wheel 2 through the first separation spring 18.

[0032] When the first friction cam 5 rotates relative to the first pawl seat 4 to the first limited angle position, and when the first inertial cam 30 rotates relative to the first pawl seat 4 to the third limited 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.

[0033] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first pawl seat 4 to the third 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.

[0035] 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. 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. When the first inertial cam 30 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 inertial cam 30 through the interaction between the third rivet 19 and the first positioning boss 9. When the first inertial cam 30 is at the fourth defined angle position relative to the first pawl seat 4, the first pawl seat 4 provides a certain angular positioning function for the first inertial cam 30 through the interaction between the third rivet 19 and the second positioning boss 17.

[0036] Preferably, in the initial state, the first friction cam 5 is at the first defined angle position relative to the first pawl seat 4, and the first inertial cam 30 is at the third defined angle position relative to the first pawl seat 4. The first pawl 1 and the first friction wheel 2 can be engaged or disengaged, and the first release spring 18 interacts with the first friction wheel 2 through friction. 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 of the first pawl seat 4 in the reverse direction or the angular deceleration in the clockwise direction is greater than a certain range, under the action of rotational inertia, the first inertial cam 30 overcomes the action of various frictional torques, thereby allowing the first inertial cam 30 to rotate relative to the first pawl seat 4 to the fourth limited angle position.

[0037] like Figure 7As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first pawl seat 4 to the third 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 friction 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 of the first pawl seat 4 in the reverse direction or the angular deceleration in the forward direction is greater than a certain range, under the action of rotational inertia, the first inertial cam 30 overcomes the action of various frictional torques, thereby allowing the first inertial cam 30 to rotate relative to the first pawl seat 4 to the fourth defined angular position.

[0038] like Figure 8 As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertia cam 30 rotates relative to the first pawl seat 4 to the fourth limited 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 the forward and reverse directions. When the absolute value of the angular acceleration in the forward direction or the angular deceleration in the reverse direction of the first pawl seat 4 is greater than a certain range, under the action of rotational inertia, the first inertia cam 30 overcomes the action of various frictional torques, thereby allowing the first inertia cam 30 to rotate relative to the first pawl seat 4 to the third limited angle position.

[0039] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first pawl seat 4 to the third 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.

[0040] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first pawl seat 4 to the fourth 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, 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.

[0041] 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.

[0044] One end of the first separation spring 18 is mounted on the first friction cam 5 via the first rivet 15. The other end of the first separation spring 18 is either in contact with or out of contact with the first friction wheel 2.

[0045] The first inertial cam 30 is rotatably mounted on the first friction cam 5 via the second rivet 16. The second rivet 16 engages with the axial groove 26 of the first inertial cam 30, thereby allowing the first inertial cam 30 to rotate relative to the first friction cam 5 between a third and a fourth defined angle.

[0046] The first friction cam 5 is rotatably mounted on the first pawl seat 4 via the first friction cam bearing 12. Optionally, the first friction cam 5 can also be mounted on the first pawl seat 4 via a sliding bearing or a clearance fit with a shaft hole. The radial protrusion 23 of the first friction cam 5 engages with the radial groove 21 of the first pawl seat 4, thereby allowing the first friction cam 5 to rotate relative to the first pawl seat 4 between a first defined angle and a second defined angle.

[0047] like Figures 13-14 As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the first limited angle position, and when the first inertial cam 30 rotates relative to the first friction cam 5 to the third limited angle position, the first pawl 1 and the first friction wheel 2 can be engaged or disengaged, and the first separation spring 18 and the first friction wheel 2 interact through friction.

[0048] like Figure 15 As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first friction cam 5 to the third limited angle position, 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.

[0049] like Figure 16 As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first friction cam 5 to the fourth limited angle position, the first pawl 1 disengages from the first friction wheel 2. Under the action of the separation boss 35 of the first inertial cam 30 (i.e., under the action of the first inertial cam 30), the first separation spring 18 disengages from the first friction wheel 2.

[0050] The first inertial cam 30 has a first positioning boss 9 and a second positioning boss 17 in its axial groove 26. The number of the second rivet 16, the first positioning boss 9, and the second positioning boss 17 can be set according to the actual working conditions.

[0051] When the first inertial cam 30 is at the third defined angle relative to the first friction cam 5, the first friction cam 5 provides a certain angular positioning function for the first inertial cam 30 through the interaction between the second rivet 16 and the first positioning boss 9. When the first inertial cam 30 is at the fourth defined angle relative to the first friction cam 5, the first friction cam 5 provides a certain angular positioning function for the first inertial cam 30 through the interaction between the second rivet 16 and the second positioning boss 17.

[0052] The rest is similar to Example 1.

[0053] Example 3

[0054] Friction-actuated friction clutches with inertial cams, such as Figures 17-24 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 first rivet 15, a second rivet 16, a first separation spring 18, and a first inertia cam 30.

[0055] One end of the first separation spring 18 is mounted on the first friction cam 5 via the first rivet 15. The other end of the first separation spring 18 is either in contact with or out of contact with the first friction wheel 2.

[0056] The first inertial cam 30 is rotatably mounted on the first release spring 18 via the second rivet 16. The second rivet 16 engages with the axial groove 26 of the first inertial cam 30, thereby allowing the first inertial cam 30 to rotate relative to the first release spring 18 between a third and a fourth defined angle.

[0057] 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 sliding bearing or a clearance fit through a shaft hole. The radial protrusion 23 of the first friction cam 5 engages with the radial groove 21 of the first pawl seat 4, thereby allowing the first friction cam 5 to rotate relative to the first pawl seat 4 between a first defined angle and a second defined angle.

[0058] like Figures 21-22 As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the first limited angle position, and when the first inertial cam 30 rotates relative to the first separation spring 18 to the third limited angle position, the first pawl 1 and the first friction wheel 2 can be engaged or disengaged, and the first separation spring 18 and the first friction wheel 2 interact through friction.

[0059] like Figure 23 As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first separation spring 18 to the third limited angle position, 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.

[0060] like Figure 24 As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first separation spring 18 to the fourth limited angle position, the first pawl 1 disengages from the first friction wheel 2. Through the cooperation of the separation boss 35 of the first inertial cam 30 and the axial boss 27 of the first friction cam 5, the first separation spring 18 disengages from the first friction wheel 2.

[0061] The rest is similar to Example 2.

[0062] Example 4

[0063] Friction-actuated friction clutches with inertial cams, such as Figures 25-34 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 first rivet 15, a second rivet 16, a first separation spring 18, and a first inertia cam 30.

[0064] The first separation spring 18 includes a first separation spring bracket 31 and a first separation spring friction pad 32. The first separation spring bracket 31 has a large elastic deformation capacity. One end of the first separation spring bracket 31 is mounted on the first friction wheel 2 via the first rivet 15. The other end of the first separation spring bracket 31 is fixedly connected to the first separation spring friction pad 32 via the second rivet 16. Thus, the first separation spring bracket 31 and the first separation spring friction pad 32 are connected to each other to form a whole (i.e., the first separation spring 18). The first separation spring friction pad 32 is in contact with or out of contact with the first friction cam 5. Therefore, overall, the first separation spring 18 and the first friction cam 5 are in contact with or out of contact.

[0065] The first inertial cam 30 includes a first inertial cam support 33, a second inertial cam support 36, and a first inertial cam rivet 37. Under the action of the first friction wheel 2, the first inertial cam support 33, the second inertial cam support 36, and the first inertial cam rivet 37 are connected to each other to form a whole (i.e., the first inertial cam 30). The first inertial cam rivet 37 cooperates with the axial groove 28 of the first friction wheel 2, thereby allowing the first inertial cam 30 to rotate relative to the first friction wheel 2 between a third defined angle and a fourth defined angle.

[0066] The first friction cam 5 includes a first friction cam support 51 and a second friction cam support 52. Under the action of the first pawl 1, the first friction cam support 51 and the second friction cam support 52 are connected to each other to form a whole (i.e., the first friction cam 5).

[0067] The axial groove 28 of the first friction wheel 2 is provided with a first positioning boss 9 and a second positioning boss 17. The number of the first positioning boss 9, the second positioning boss 17, and the first inertial cam rivet 37 can be set according to the actual working conditions.

[0068] The first friction wheel 2, the first friction cam 5, and the first inertia cam 30 are all coaxially arranged 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 friction-actuated friction clutch with inertia cam") via splines.

[0069] 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.

[0070] 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 29 of the first friction cam support 51 engages with the radial groove 21 of the first pawl seat 4, thereby allowing the first friction cam 5 to rotate relative to the first pawl seat 4 between a first defined angle and a second defined angle. When the first separation spring friction pad 32 is in contact with the first friction cam 5, under the elastic action of the first separation spring support 31, the first separation spring friction pad 32 and the first friction cam 5 interact through friction, that is, the first separation spring 18 and the first friction cam 5 interact through friction, and the first friction wheel 2 interacts with the first friction cam 5 through the first separation spring 18.

[0071] When the first friction cam 5 rotates relative to the first pawl seat 4 to the first limited angle position, and when the first inertial cam 30 rotates relative to the first friction wheel 2 to the third limited 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 cam 5 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.

[0072] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first friction wheel 2 to the third 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 cam 5 through friction.

[0073] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first friction wheel 2 to the fourth 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. Under the action of the separation boss 38 of the first inertial cam support 33 and the separation boss 39 of the second inertial cam support 36 (i.e., under the action of the first inertial cam 30), the first separation spring 18 disengages from the first friction cam 5.

[0074] Furthermore, when the first inertial cam 30 is at the third defined angular position relative to the first friction wheel 2, the first friction wheel 2 provides a certain angular positioning function for the first inertial cam 30 through the interaction between the first inertial cam rivet 37 and the first positioning boss 9. When the first inertial cam 30 is at the fourth defined angular position relative to the first friction wheel 2, the first friction wheel 2 provides a certain angular positioning function for the first inertial cam 30 through the interaction between the first inertial cam rivet 37 and the second positioning boss 17.

[0075] Preferably, in the initial state, the first friction cam 5 is at the first defined angle position relative to the first pawl seat 4, and the first inertial cam 30 is at the third defined angle position relative to the first friction wheel 2. The first pawl 1 and the first friction wheel 2 can be engaged or disengaged. The first release spring 18 interacts with the first friction cam 5 through friction. Figures 29-30 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 friction wheel 2 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 frictional action of the first separation spring 18, 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 of the first friction wheel 2 in the clockwise direction or the angular deceleration in the reverse direction is greater than a certain range, under the action of rotational inertia, the first inertial cam 30 overcomes the action of various frictional torques, thereby allowing the first inertial cam 30 to rotate relative to the first friction wheel 2 to the fourth limited angle position.

[0076] like Figures 31-32As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first friction wheel 2 to the third 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 cam 5 through friction. At this time, when the absolute value of the angular acceleration or angular deceleration of the first friction wheel 2 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 friction wheel 2 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 release spring 18, 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 of the first friction wheel 2 in the forward rotation direction or the angular deceleration in the reverse rotation direction is greater than a certain range, under the action of rotational inertia, the first inertial cam 30 overcomes the action of various frictional torques, thereby allowing the first inertial cam 30 to rotate relative to the first friction wheel 2 to the fourth defined angular position.

[0077] like Figures 33-34 As shown, when the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertia cam 30 rotates relative to the first friction wheel 2 to the fourth limited angle position, the first pawl 1 disengages from the first friction wheel 2, and the first release spring 18 disengages from the first friction cam 5. At this time, when the absolute value of the angular acceleration or angular deceleration of the first friction wheel 2 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 in the reverse direction or the angular deceleration in the forward direction of the first friction wheel 2 is greater than a certain range, under the action of rotational inertia, the first inertia cam 30 overcomes the action of various frictional torques, thereby allowing the first inertia cam 30 to rotate relative to the first friction wheel 2 to the third limited angle position.

[0078] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first friction wheel 2 to the third limited angle position, and when the absolute value of the angular acceleration or angular deceleration of the first friction wheel 2 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.

[0079] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the first inertial cam 30 rotates relative to the first friction wheel 2 to the fourth limited angle position, and when the absolute value of the angular acceleration or angular deceleration of the first friction wheel 2 is less than a certain range, the first pawl 1 disengages from the first friction wheel 2, and the first friction cam 5 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 cam 5 is also avoided.

[0080] When the first release spring 18 and the first friction cam 5 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 cam 5 can be stably maintained within a certain range within a certain service time. Furthermore, it can compensate for some wear between the first release spring 18 and the first friction cam 5, thereby ensuring stable friction between the first release spring 18 and the first friction cam 5 within a certain service time.

[0088] The first friction cam 5 is rotatably mounted on the first pawl seat 4 via the second rivet 16. The second rivet 16 engages with the axial groove 20 of the first pawl seat 4, thereby allowing the first friction cam 5 to rotate relative to the first pawl seat 4 between a first defined angle and a second defined angle. When the first release spring 18 is in contact with the first friction cam 5, under the elastic action of the first release spring 18, the first release spring 18 and the first friction cam 5 interact through friction; that is, the first friction wheel 2 interacts with the first friction cam 5 through the first release spring 18.

[0089] like Figures 39-40 As shown, when the first friction cam 5 is at the first defined angle position relative to the first pawl seat 4, and when the first inertial cam 30 is at the third defined angle position relative to the first separation spring 18, 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 and the first friction cam 5 interact 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.

[0090] like Figures 41-42As shown, when the first friction cam 5 is at the second limited angle position relative to the first pawl seat 4, and when the first inertial cam 30 is at the third limited angle position relative to the first separation spring 18, 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 cam 5 through friction.

[0091] like Figures 43-44 As shown, when the first friction cam 5 is at the second limited angle position relative to the first pawl seat 4, and when the first inertia cam 30 is at the fourth limited angle position relative to the first separation spring 18, 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. Through the cooperation of the separation boss 35 of the first inertia cam 30 and the separation boss 40 of the first friction wheel 2, the first separation spring 18 disengages from the first friction cam 5.

[0092] Furthermore, when the first inertial cam 30 is at the third defined angle position relative to the first separation spring 18, the first separation spring 18 provides a certain angular positioning function for the first inertial cam 30 through the interaction between the first rivet 15 and the first positioning boss 9. When the first inertial cam 30 is at the fourth defined angle position relative to the first separation spring 18, the first separation spring 18 provides a certain angular positioning function for the first inertial cam 30 through the interaction between the first rivet 15 and the second positioning boss 17.
