Friction-actuated friction clutch provided with centrifugal blocks

Abstract

The invention provides a friction actuating type friction clutch with centrifugal blocks, which is mainly applied to the technical field of transmission, in particular to the technical field of friction clutches. The clutch at least comprises a pawl, a friction wheel, a return spring, a pawl seat, a friction cam, a separation spring and a centrifugal block. Under the centrifugal effect of the centrifugal block and the elastic force effect of the separation spring, the separation spring and the friction wheel are selectively contacted, or the separation spring and the friction wheel are selectively separated from each other; 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 friction actuating type friction clutch with the centrifugal blocks 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 a centrifugal block, mainly 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 in friction wheel clutches, this invention aims to provide a friction-actuated friction clutch with a centrifugal block. This friction-actuated friction clutch with a centrifugal block 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 friction-actuated friction clutch with a centrifugal block includes: a pawl, a friction wheel, a return spring, a pawl seat, a friction cam, a release spring, and a centrifugal block. 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, and the other end of the release spring is in contact with the friction wheel, or the other end of the release spring is disengaged from the friction wheel. Alternatively, one end of the release spring is mounted on the friction wheel, and the other end of the release spring is in contact with the friction cam, or the other end of the release spring is disengaged from the friction cam. The centrifugal block is mounted on the release spring. When the centrifugal block's rotational speed is less than a certain range, the release spring contacts the friction wheel or the friction cam. When the centrifugal block's rotational speed is greater than a certain range, the release spring disengages from the friction wheel or the friction cam. 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, and when the centrifugal block's rotational speed is less than a certain range, the pawl selectively disengages from the friction wheel under the friction of the release spring or the friction wheel. When the release spring is in contact with the friction wheel, and when the centrifugal block's rotational speed is less than a certain range, the pawl selectively engages or disengages from the friction wheel under the friction of the release spring or the friction wheel. The friction wheel and the ratchet seat are respectively connected to external components (the external components refer to components excluding the "friction-actuated friction clutch with centrifugal block").

[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.

When the rotational speed of the first centrifugal block 28 is less than a certain range, the first separation spring 18 contacts the first friction wheel 2; when the rotational speed of the first centrifugal block 28 is greater than a certain range, the first separation spring 18 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.

The first centrifugal block 28 is mounted on the first separation spring 18. When the rotational speed of the first centrifugal block 28 is less than a certain range, the first separation spring 18 contacts the first friction cam 5; when the rotational speed of the first centrifugal block 28 is greater than a certain range, the first separation spring 18 disengages from the first friction cam 5. 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 first friction cam 5 rotates relative to the first pawl seat 4 to the first limited angle position, the first pawl 1 selectively engages and disengages from 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.

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 second limited angle. One end of the first separation spring 18 is disposed on the first friction cam 5, and the other end of the first separation spring 18 is in contact with the first friction wheel 2, or the other end of the first separation spring 18 is disengaged from the first friction wheel 2. The first centrifugal block 28 is disposed on the first separation spring 18, and when the rotational speed of the first centrifugal block 28 is less than a certain range, the first separation spring 18 is in contact with the first friction wheel 2; when the rotational speed of the first centrifugal block 28 is greater than a certain range, the first separation spring 18 is disengaged 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 first friction cam 5 rotates relative to the first pawl seat 4 to the first predetermined angle position, the first pawl 1 selectively engages and disengages from the first friction wheel 2. When the first friction cam 5 rotates relative to the first pawl seat 4 to the second predetermined angle position, the first pawl 1 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.

[0009] 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 separation spring includes a first separation 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 second limited angle. One end of the first separation spring 18 is disposed on the first friction wheel 2, and the other end of the first separation spring 18 is in contact with the first friction cam 5, or the other end of the first separation spring 18 is disengaged from the first friction cam 5. The first centrifugal block 28 is disposed on the first separation spring 18, and when the rotational speed of the first centrifugal block 28 is less than a certain range, the first separation spring 18 is in contact with the first friction cam 5; when the rotational speed of the first centrifugal block 28 is greater than a certain range, the first separation spring 18 is disengaged from the first friction cam 5. 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 first friction cam 5 rotates relative to the first pawl seat 4 to the first predetermined angle position, the first pawl 1 selectively engages and disengages from the first friction wheel 2. When the first friction cam 5 rotates relative to the first pawl seat 4 to the second predetermined angle position, the first pawl 1 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.

[0010] Furthermore, when the friction cam rotates relative to the ratchet seat to the first defined angle position, the friction cam and the ratchet seat have an angle positioning function. When the friction cam rotates relative to the ratchet seat to the second defined angle position, the friction cam and the ratchet seat have an angle positioning function.

[0011] 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.

[0012] Alternatively, the friction-actuated friction clutch with a centrifugal block further includes a positioning mechanism 8.

[0014] 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.

[0015] Compared with existing technologies, the friction-actuated friction clutch with centrifugal blocks of the present invention can reduce pawl wear and has higher transmission efficiency. The friction-actuated friction clutch of the present invention can selectively disengage the pawl from the friction wheel using the frictional action of the release spring, thereby reducing pawl wear. Furthermore, when the rotational speed exceeds a certain range, the clutch can selectively disengage the release spring from the friction wheel or the friction cam using the centrifugal action of the centrifugal blocks. Since frictional contact is avoided at this time, the transmission efficiency of the clutch in the disengaged state can be improved.

[0022] Example 1

[0023] A friction clutch with a centrifugal block, such as Figures 1-7 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 cam bearing 12, a first separation spring 18, a first centrifugal block 28, a first rivet 31, and a second rivet 32. 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 first centrifugal block 28 is mounted on the first separation spring 18, and the first separation spring friction pad 182 and the first centrifugal block 28 are fixedly connected to the other end of the first separation spring bracket 181 via the second rivet 32. Thus, the first separation spring bracket 181 and the first separation spring friction pad 182 are interconnected to form a whole (i.e., the first separation spring 18). The first separation spring friction pad 182 is either in contact with or out of contact with the first friction wheel 2. Therefore, overall, the first separation spring 18 and the first friction wheel 2 are either in contact or out of contact.

[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 friction-actuated friction clutch with centrifugal blocks") via splines.

[0025] Preferably, the first friction cam 5 is rotatably mounted on the first pawl seat 4 via the first cam bearing 12. Optionally, the first friction cam 5 may also be mounted on the first pawl seat 4 via a sliding bearing or a clearance fit with a shaft hole. 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 tooth 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.

[0026] 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 23 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.

[0027] When the rotational speed of the first centrifugal block 28 is less than a certain range, the centrifugal force of the first centrifugal block 28 is less than the elastic force of the first separation spring support 181, and the first separation spring friction pad 182 is in contact with the first friction wheel 2, meaning that the first separation spring 18 is generally in contact with the first friction wheel 2. When the rotational speed of the first centrifugal block 28 is greater than a certain range, the centrifugal force of the first centrifugal block 28 is greater than the elastic force of the first separation spring support 181, and under the action of the first centrifugal block 28, the first separation spring friction pad 182 disengages from the first friction wheel 2, meaning that the first separation spring 18 is generally disengaged from the first friction wheel 2. Thus, under the centrifugal force of the first centrifugal block 28 and the elastic force of the first separation spring 18, the first separation spring 18 selectively disengages from the first friction wheel 2.

[0028] When the rotational speed of the first centrifugal block 28 is less than a certain range, under the friction of the first friction wheel 2, the first separation spring 18 drives the first friction cam 5 to rotate relative to the first pawl seat 4. When the first friction cam 5 rotates relative to the first pawl seat 4 to the first 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. 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.

[0029] When the rotational speed of the first centrifugal block 28 is less than a certain range, under the friction of the first friction wheel 2, the first separation spring 18 drives the first friction cam 5 to rotate relative to the first pawl seat 4. 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.

[0030] Preferably, in the initial state, the first friction cam 5 is positioned at the first defined angle relative to the first pawl seat 4, such as... Figure 5 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 rotational speed of the first centrifugal block 28 is less than a certain range, and under the friction of the first friction wheel 2, when the first separation spring 18 drives the first friction cam 5 to rotate clockwise relative to the first pawl seat 4 (rotation direction indicated by the arrow in the figure), the first friction cam 5 can rotate relative to the first pawl seat 4 to the second limited angle position.

[0031] like Figure 6 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 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 rotational speed of the first centrifugal block 28 is less than a certain range, and under the frictional action of the first friction wheel 2, when the first separation spring 18 drives the first friction cam 5 to rotate relative to the first pawl seat 4 in the reverse direction (opposite to the rotation direction indicated by the arrow in the figure), the first friction cam 5 can rotate relative to the first pawl seat 4 to the first limited angle position.

[0032] like Figure 6 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 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 rotational speed of the first centrifugal block 28 is greater than a certain range, the centrifugal force of the first centrifugal block 28 is greater than the elastic force of the first separation spring 18. Therefore, under the action of the first centrifugal block 28, the first separation spring 18 disengages from the first friction wheel 2, as... Figure 7 As shown.

[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 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 frictional contact between the pawl and the friction wheel.

[0034] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the rotational speed of the first centrifugal block 28 is greater than a certain range, 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, not only is frictional contact between the pawl and the friction wheel avoided, but frictional contact between the first separation spring 18 and the first friction wheel 2 is also avoided.

[0035] When the first separation spring friction pad 182 and the first friction wheel 2 interact through friction, some wear is inevitable after prolonged operation. However, because the first separation spring bracket 181 has a large elastic deformation capacity, the contact pressure between the first separation spring friction pad 182 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 separation spring friction pad 182 and the first friction wheel 2, thereby ensuring stable friction between them within a certain service life.

[0036] Example 2

[0037] A friction clutch with a centrifugal block, such as Figures 8-14 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 cam bearing 12, a first separation spring 18, a first centrifugal block 28, a first rivet 31, and a second rivet 32. The first separation spring 18 includes a first separation spring bracket 181 and a first separation spring friction pad 182.

[0038] One end of the first separation spring bracket 181 is mounted on the first friction wheel 2 via the first rivet 31. The first centrifugal block 28 is mounted on the first separation spring 18, and the first separation spring friction pad 182 and the first centrifugal block 28 are fixedly connected to the other end of the first separation spring bracket 181 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 cam 5. Therefore, overall, the first separation spring 18 and the first friction cam 5 are in contact with or out of contact.

[0039] When the rotational speed of the first centrifugal block 28 is less than a certain range, the centrifugal force of the first centrifugal block 28 is less than the elastic force of the first separation spring support 181, and the first separation spring friction pad 182 contacts the first friction cam 5, meaning that the first separation spring 18 is generally in contact with the first friction cam 5. When the rotational speed of the first centrifugal block 28 exceeds a certain range, the centrifugal force of the first centrifugal block 28 is greater than the elastic force of the first separation spring support 181, and under the action of the first centrifugal block 28, the first separation spring friction pad 182 disengages from the first friction cam 5, meaning that the first separation spring 18 is generally disengaged from the first friction cam 5. Thus, under the centrifugal force of the first centrifugal block 28 and the elastic force of the first separation spring 18, the first separation spring 18 selectively disengages from the first friction cam 5.

[0040] When the rotational speed of the first centrifugal block 28 is less than a certain range, the first friction cam 5 rotates relative to the first pawl seat 4 under the frictional action of the first separation spring 18. 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 can be engaged or disengaged under the action of the first return spring 3 and the first friction cam 5. When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, the first pawl 1 and the first friction wheel 2 disengage under the action of the first return spring 3 and the first friction cam 5.

[0041] When the rotational speed of the first centrifugal block 28 is greater than a certain range, the centrifugal force of the first centrifugal block 28 is greater than the elastic force of the first separation spring 18. Under the action of the first centrifugal block 28, the first separation spring 18 disengages from the first friction cam 5.

[0042] The rest is similar to Example 1.

[0043] Example 3

[0044] A friction clutch with a centrifugal block, such as Figures 15-21As shown, the system 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 separation spring 18, a first centrifugal block 28, a first rivet 31, and a second rivet 32. The first separation spring 18 includes a first separation spring bracket 181 and a first separation spring friction pad 182. The first friction cam 5 includes a first cam bracket 51 and a second cam bracket 52. Under the action of the first pawl 1, the first cam bracket 51 and the second cam bracket 52 are connected to each other as a whole (i.e., the first friction cam 5). 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 first centrifugal block 28 is mounted on the first separation spring 18, and the first separation spring friction pad 182 and the first centrifugal block 28 are fixedly connected to the other end of the first separation spring bracket 181 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 as 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.

[0045] The first cam support 51 is provided with a first positioning boss 9, and the first pawl seat 4 is provided with a first positioning groove 10 and a second positioning groove 11. The number of the first positioning boss 9, the first positioning groove 10 and the second positioning groove 11 can be set according to the actual working conditions.

[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 friction-actuated friction clutch with centrifugal blocks") via splines.

[0047] The first cam support 51 is rotatably mounted on the first pawl seat 4 via a clearance fit through a shaft hole, and 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 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.

[0048] 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.

[0049] When the rotational speed of the first centrifugal block 28 is less than a certain range, the centrifugal force of the first centrifugal block 28 is less than the elastic force of the first separation spring support 181, and the first separation spring friction pad 182 is in contact with the first friction wheel 2, meaning that the first separation spring 18 is generally in contact with the first friction wheel 2. When the rotational speed of the first centrifugal block 28 exceeds a certain range, the centrifugal force of the first centrifugal block 28 is greater than the elastic force of the first separation spring support 181, and under the action of the first centrifugal block 28, the first separation spring friction pad 182 disengages from the first friction wheel 2, meaning that the first separation spring 18 is generally disengaged from the first friction wheel 2. Thus, under the centrifugal action of the first centrifugal block 28, the first separation spring 18 selectively disengages from the first friction wheel 2.

[0050] When the rotational speed of the first centrifugal block 28 is less than a certain range, under the frictional action of the first friction wheel 2, the first separation spring 18 drives the first friction cam 5 to rotate relative to the first pawl seat 4. When the first friction cam 5 rotates relative to the first pawl seat 4 to the first 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. 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.

[0051] 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 friction-actuated friction clutch with centrifugal block has a certain shifting reliability and stability at the first defined angle position.

[0052] When the rotational speed of the first centrifugal block 28 is less than a certain range, under the friction of the first friction wheel 2, the first separation spring 18 drives the first friction cam 5 to rotate relative to the first pawl seat 4. 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.

[0053] 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 friction-actuated friction clutch with centrifugal block has a certain shifting reliability and stability at the second defined angle position.

[0054] Preferably, in the initial state, the first friction cam 5 is positioned at the first defined angle relative to the first pawl seat 4, such as... Figure 19 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 rotational speed of the first centrifugal block 28 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 friction cam 5 can rotate relative to the first pawl seat 4 to the second limited angle position.

[0055] like Figure 20As 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 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 rotational speed of the first centrifugal block 28 is less than a certain range, and when the first friction wheel 2 rotates in the reverse direction relative to the first pawl seat 4 (opposite to the rotation direction indicated by the arrow in the figure), under the frictional action of the first friction wheel 2, the first friction cam 5 can rotate relative to the first pawl seat 4 to the first limited angle position.

[0056] like Figure 21 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 friction wheel 2 rotates relative to the first pawl seat 4 in the forward rotation direction (the rotation direction indicated by the arrow in the figure). When the rotational speed of the first centrifugal block 28 is greater than a certain range, under the centrifugal action of the first centrifugal block 28, the first separation spring 18 disengages from the first friction wheel 2, as... Figure 21 As shown.

[0057] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, 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 frictional contact between the pawl and the friction wheel.

[0058] When the first friction cam 5 rotates relative to the first pawl seat 4 to the second limited angle position, and when the rotational speed of the first centrifugal block 28 is greater than a certain range, 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, not only is frictional contact between the pawl and the friction wheel avoided, but frictional contact between the first separation spring 18 and the first friction wheel 2 is also avoided.

[0059] When the first separation spring friction pad 182 and the first friction wheel 2 interact through friction, some wear is inevitable after prolonged operation. However, because the first separation spring bracket 181 has a large elastic deformation capacity, the contact pressure between the first separation spring friction pad 182 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 separation spring friction pad 182 and the first friction wheel 2, thereby ensuring stable friction between them within a certain service life.

[0060] Example 4

[0061] A friction clutch with a centrifugal block, such as Figures 22-33 As shown, the system 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 centrifugal block 28, a first rivet 31, and a second rivet 32. The first separation spring 18 includes a first separation spring bracket 181 and a first separation spring friction pad 182. One end of the first separation spring bracket 181 is mounted on the first friction cam 5 via the first rivet 31. The first centrifugal block 28 is mounted on the first separation spring 18, and the first separation spring friction pad 182 and the first centrifugal block 28 are fixedly connected to the other end of the first separation spring bracket 181 via the second rivet 32. Thus, the first separation spring bracket 181 and the first separation spring friction pad 182 are interconnected to form a single unit (i.e., the first separation spring 18). The first separation spring friction pad 182 is either in contact with or out of contact with the first friction wheel 2. Therefore, overall, the first separation spring 18 and the first friction wheel 2 are either in contact or out of contact.

[0062] The first pawl seat 4 is provided with a first positioning groove 10 and a second positioning groove 11, such as Figure 25 As shown. The number of the positioning mechanism 8, the first positioning groove 10, and the second positioning groove 11 can be set according to the actual working conditions.

[0063] The positioning mechanism 8 is fixed to 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 26 As shown.

[0064] 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 friction-actuated friction clutch with centrifugal blocks") via splines.

[0065] The first friction cam 5 is mounted on the first pawl seat 4 with a clearance fit through a shaft hole, and the first friction cam 5 is rotatable relative to the first pawl seat 4. 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 axial boss 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 limited angle and a second limited angle.

[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] When the rotational speed of the first centrifugal block 28 is less than a certain range, the centrifugal force of the first centrifugal block 28 is less than the elastic force of the first separation spring support 181, and the first separation spring friction pad 182 is in contact with the first friction wheel 2, meaning that the first separation spring 18 is generally in contact with the first friction wheel 2. When the rotational speed of the first centrifugal block 28 exceeds a certain range, the centrifugal force of the first centrifugal block 28 is greater than the elastic force of the first separation spring support 181, and under the action of the first centrifugal block 28, the first separation spring friction pad 182 disengages from the first friction wheel 2, meaning that the first separation spring 18 is generally disengaged from the first friction wheel 2. Thus, under the centrifugal action of the first centrifugal block 28, the first separation spring 18 selectively disengages from the first friction wheel 2.

[0068] When the rotational speed of the first centrifugal block 28 is less than a certain range, under the friction of the first friction wheel 2, the first separation spring 18 drives the first friction cam 5 to rotate relative to the first pawl seat 4. When the first friction cam 5 rotates relative to the first pawl seat 4 to the first 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. 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.

[0069] 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 friction-actuated friction clutch with centrifugal block provides a certain degree of shifting reliability and stability at the first defined angle position.

[0070] When the rotational speed of the first centrifugal block 28 is less than a certain range, under the friction of the first friction wheel 2, the first separation spring 18 drives the first friction cam 5 to rotate relative to the first pawl seat 4. Under the friction of 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, 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.

[0071] 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 friction-actuated friction clutch with centrifugal block provides a certain degree of shifting reliability and stability at the second defined angle position.

[0072] When the rotational speed of the first centrifugal block 28 is greater than a certain range, the centrifugal force of the first centrifugal block 28 is greater than the elastic force of the first separation spring 18. Under the action of the first centrifugal block 28, the first separation spring 18 disengages from the first friction wheel 2.

[0073] The rest is similar to Example 1.
