Benefits of technology

[0007]According to an embodiment of the present invention, the electromagnetic clutch brake, because the electromagnetic device is located on one side of the second transmission wheel along the axial direction of the output shaft, can reduce the structural size of the electromagnetic clutch brake compared to the scheme where the electromagnetic device is arranged on both sides of the second transmission wheel, thus occupying less space. Furthermore, since the electromagnetic device is located on one side of the second transmission wheel along the axial direction of the output shaft, it is easier to disassemble, assemble, and maintain the electromagnetic device. On the other hand, when the electromagnetic device is de-energized, it presses the friction assembly towards the second transmission wheel, so that the first and second friction plates have axial clamping force.

When the electromagnetic device is energized, it can release the axial clamping force between the first and second friction plates, thus restricting the rotation of the second transmission wheel and braking the output shaft. Since the electromagnetic clutch brake is in a de-energized state most of the time, its energy consumption is reduced.

Description

Technical Field

[0001] This utility model relates to the field of cable car technology, specifically to an electromagnetic clutch brake and a cable car system. Background Technology

[0002] Cableway systems typically include electromagnetic clutch brakes, which adjust the distance between two gondolas to ensure they always maintain a set spacing on the track and prevent collisions within stations. Electromagnetic clutch brakes play a crucial role in the safe operation of the cableway and the safety of passengers. However, electromagnetic clutch brakes suffer from drawbacks such as large size, high energy consumption, and difficulty in disassembly, assembly, and maintenance. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose an electromagnetic clutch brake, which has the advantages of simple structure, small space occupation, convenient assembly, disassembly and maintenance, easy adjustment of braking gap and low energy consumption.

[0005] An embodiment of this utility model also proposes a cableway system.

[0006] The electromagnetic clutch brake of this utility model includes: an output shaft; a power wheel rotatably connected to the output shaft; a transmission device including a first transmission wheel, a second transmission wheel, and a friction assembly, wherein the first transmission wheel is fixedly connected to the power wheel, the second transmission wheel is fixedly connected to the output shaft, the inner wall of the first transmission wheel has a first spline, the outer wall of the second transmission wheel has a second spline, the first spline and the second spline are arranged opposite each other radially along the output shaft, the friction assembly includes a first friction plate and a second friction plate, the first friction plate and the second friction plate are arranged sequentially along the axial direction of the output shaft, the first friction plate is engaged with the first spline, and the second friction plate is engaged with the second spline; and an electromagnetic device disposed on one side of the second transmission wheel along the axial direction of the output shaft. When the electromagnetic device is de-energized, the electromagnetic device presses the friction assembly toward the second transmission wheel to give the first friction plate and the second friction plate an axial clamping force; when the electromagnetic device is energized, the electromagnetic device can release the axial clamping force between the first friction plate and the second friction plate and stop the second transmission wheel from rotating.

[0007] According to an embodiment of the present invention, the electromagnetic clutch brake, because the electromagnetic device is located on one side of the second transmission wheel along the axial direction of the output shaft, can reduce the structural size of the electromagnetic clutch brake compared to the scheme where the electromagnetic device is arranged on both sides of the second transmission wheel, thus occupying less space. Furthermore, since the electromagnetic device is located on one side of the second transmission wheel along the axial direction of the output shaft, it is easier to disassemble, assemble, and maintain the electromagnetic device. On the other hand, when the electromagnetic device is de-energized, it presses the friction assembly towards the second transmission wheel, so that the first and second friction plates have axial clamping force. Thus, the power of the drive wheel can be transmitted along the path of the first transmission wheel, the first friction plate, the second friction plate, the second transmission wheel, and the output shaft, causing the drive wheel to drive the output shaft to rotate. When the electromagnetic device is energized, it can release the axial clamping force between the first and second friction plates, thus restricting the rotation of the second transmission wheel and braking the output shaft. Since the electromagnetic clutch brake is in a de-energized state most of the time, its energy consumption is reduced.

[0008] In some embodiments, the electromagnetic device includes an electromagnetic coil, an armature assembly, and an elastic element. The output shaft rotatably passes through the electromagnetic coil. The armature assembly is disposed between the electromagnetic coil and the second transmission wheel. The armature assembly slides with the second spline along the axial direction of the output shaft. The elastic element is connected to the armature assembly and presses the armature assembly toward the second transmission wheel. When the electromagnetic coil is de-energized, the elastic element drives the armature assembly to move toward the second transmission wheel, so that there is an axial clamping force between the first friction plate and the second friction plate. When the electromagnetic coil is energized, the electromagnetic coil drives the armature assembly to move away from the second transmission wheel, so as to release the axial clamping force between the first friction plate and the second friction plate, and the armature assembly can stop the second transmission wheel from rotating.

[0009] In some embodiments, the armature assembly includes an armature and a first pressure block, the first pressure block being fixedly mounted on the side of the armature facing the friction assembly, the inner peripheral wall of the first pressure block engaging with the second spline, the elastic element being connected to the armature, and when the electromagnetic coil is de-energized, the first pressure block abutting against the friction assembly along the axial direction of the output shaft, and when the electromagnetic coil is energized, the first pressure block being spaced apart from the friction assembly along the axial direction of the output shaft.

[0010] In some embodiments, the electromagnetic clutch brake further includes a first sleeve, which is detachably mounted on the output shaft and abuts against the second transmission wheel, and the elastic element is disposed between the outer peripheral wall of the first sleeve and the inner peripheral wall of the armature.

[0011] In some embodiments, the electromagnetic clutch brake further includes a stop block disposed between the outer peripheral wall of the first sleeve and the inner peripheral wall of the armature, and fixed relative to the first sleeve. One end of the elastic member abuts against the stop block, and the other end of the elastic member abuts against the armature.

[0012] In some embodiments, the elastic element is a disc spring, which is sleeved on the outer periphery of the first sleeve, and the outer ring of the disc spring abuts against the armature.

[0013] In some embodiments, the electromagnetic clutch brake includes a second sleeve sleeved on the outside of the first sleeve, and the electromagnetic device further includes a first bearing mounted between the outer peripheral wall of the second sleeve and the inner peripheral wall of the electromagnetic coil. The position of the second sleeve relative to the armature along the axial direction of the output shaft is adjustable.

[0014] In some embodiments, the electromagnetic clutch brake further includes a first retaining ring, which is disposed on one side of the first sleeve along the axial direction of the output shaft and is fixedly connected to the first sleeve. The first retaining ring is disposed inside the second sleeve, and the outer peripheral wall of the first retaining ring is threadedly connected to the inner peripheral wall of the second sleeve, so that the position of the second sleeve relative to the armature along the axial direction of the output shaft is adjustable.

[0015] In some embodiments, the inner peripheral wall of the second sleeve has an annular flange, which is threadedly engaged with the first retaining ring. The electromagnetic clutch brake further includes a second retaining ring, which is detachably mounted on the side of the annular flange away from the first sleeve, and the second retaining ring abuts against the annular flange.

[0016] In some embodiments, the electromagnetic clutch brake further includes a first threaded component, which is sequentially threaded through the second retaining ring, the first retaining ring, and the first sleeve along the axial direction of the output shaft.

[0017] In some embodiments, the electromagnetic clutch brake further includes a second threaded component, which is sequentially threaded through the first sleeve and the output shaft along the axial direction of the output shaft.

[0018] In some embodiments, the electromagnetic clutch brake further includes a third threaded component, which is sequentially threaded through the second retaining ring and the first retaining ring along the axial direction of the output shaft.

[0019] In some embodiments, the friction assembly is in multiple groups, and the multiple groups of friction assemblies are arranged sequentially along the axial direction of the output shaft.

[0020] Another embodiment of the cableway system of the present invention includes the electromagnetic clutch brake described in any one of the embodiments of the present invention.

[0021] According to the cableway system of this utility model, since the electromagnetic device is located on one side of the second transmission wheel along the axial direction of the output shaft, compared to the scheme where the electromagnetic device is arranged on both sides of the second transmission wheel, the structural size of the electromagnetic clutch brake can be reduced, occupying less space. Furthermore, since the electromagnetic device is located on one side of the second transmission wheel along the axial direction of the output shaft, it is easier to disassemble, assemble, and maintain the electromagnetic device. On the other hand, when the electromagnetic device is de-energized, it presses the friction assembly towards the second transmission wheel, so that the first and second friction plates have axial clamping force. Thus, the power of the drive wheel can be transmitted along the path of the first transmission wheel, the first friction plate, the second friction plate, the second transmission wheel, and the output shaft, causing the drive wheel to drive the output shaft to rotate. When the electromagnetic device is energized, it can release the axial clamping force between the first and second friction plates, thus limiting the rotation of the second transmission wheel and braking the output shaft. Since the electromagnetic clutch brake of the cableway system is in a de-energized state most of the time, the energy consumption of the electromagnetic clutch brake is reduced.

[0037] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] The following is a reference appendix. Figures 1 to 7 This invention describes an electromagnetic clutch brake and a cableway system according to embodiments of the present invention.

[0039] like Figures 2 to 7 As shown, the electromagnetic clutch brake of this utility model embodiment includes: an output shaft 1, a power wheel 2, a transmission device 3, and an electromagnetic device 4.

[0040] The power wheel 2 is rotatably connected to the output shaft 1. The transmission device 3 includes a first transmission wheel 31, a second transmission wheel 32, and a friction assembly 33. The first transmission wheel 31 is fixedly connected to the power wheel 2, and the second transmission wheel 32 is fixedly connected to the output shaft 1. The inner wall of the first transmission wheel 31 has a first spline 311, and the outer wall of the second transmission wheel 32 has a second spline 321. The first spline 311 and the second spline 321 are arranged opposite each other along the radial direction of the output shaft 1. The friction assembly 33 includes a first friction plate 331 and a second friction plate 332. The first friction plate 331 and the second friction plate 332 are arranged sequentially along the axial direction of the output shaft 1. The first friction plate 331 is engaged with the first spline 311, and the second friction plate 332 is engaged with the second spline 321. The electromagnetic device 4 is located on one side of the second transmission wheel 32 along the axial direction of the output shaft 1.

[0041] When the electromagnetic device 4 is de-energized, it presses the friction assembly 33 toward the second transmission wheel 32, thereby applying an axial clamping force to the first friction plate 331 and the second friction plate 332. When the electromagnetic device 4 is energized, it releases the axial clamping force between the first friction plate 331 and the second friction plate 332, and stops the second transmission wheel 32 from rotating.

[0042] According to the embodiment of the present invention, the electromagnetic clutch brake, since the electromagnetic device 4 is arranged on one side of the second transmission wheel 32 along the axial direction of the output shaft 1, can reduce the structural size of the electromagnetic clutch brake and occupy less space compared to the scheme of "the electromagnetic device 4 is arranged on both sides of the second transmission wheel 32". Furthermore, since the electromagnetic device 4 is arranged on one side of the second transmission wheel 32 along the axial direction of the output shaft 1, it is convenient to disassemble and repair the electromagnetic device 4.

[0043] On the other hand, when the electromagnetic device 4 is de-energized, it presses the friction assembly 33 towards the second transmission wheel 32, giving the first friction plate 331 and the second friction plate 332 an axial clamping force. This allows the power of the drive wheel 2 to be transmitted along the path of the first transmission wheel 31, the first friction plate 331, the second friction plate 332, the second transmission wheel 32, and the output shaft 1, thus causing the drive wheel 2 to rotate the output shaft 1. When the electromagnetic device 4 is energized, it releases the axial clamping force between the first friction plate 331 and the second friction plate 332, restricting the rotation of the second transmission wheel 32 and braking the output shaft 1. Since the electromagnetic clutch brake is de-energized most of the time, its energy consumption is reduced.

[0044] Therefore, the electromagnetic clutch brake of the present invention can be simplified in structure, occupy less space, facilitate the disassembly, assembly and maintenance of the electromagnetic clutch brake by operators, and has low energy consumption.

[0045] In related technologies, such as Figure 1 As shown, the electromagnetic device of the electromagnetic clutch brake is divided into two parts: brake 1' and clutch 2'. Brake 1' and clutch 2' are respectively arranged on both sides of the transmission wheel 3'. Therefore, the above structure results in a large axial dimension of the electromagnetic clutch brake, and it is not convenient for operators to disassemble and maintain the electromagnetic device.

[0046] In the embodiment of the present invention, the electromagnetic clutch brake has the electromagnetic device 4 arranged along the axial direction of the output shaft 1 on one side of the second transmission wheel 32, that is, the electromagnetic device 4 is arranged on one side. This simplifies the arrangement structure of the electromagnetic device 4, reduces space occupation, and makes it easier for operators to disassemble, assemble and maintain the electromagnetic device 4.

[0047] like Figure 3 and Figure 4As shown, the key teeth of the first spline 311 and the second spline 321 are both along the axial direction of the output shaft 1 (e.g., Figure 3 The friction plate 331 extends in the left-right direction. The first friction plate 331 engages with the first spline 311, meaning the first friction plate 331 can move along the axial direction of the first spline 311, but cannot rotate relative to the first spline 311. The second friction plate 332 engages with the second spline 321, meaning the second friction plate 332 can move along the axial direction of the second spline 321, but cannot rotate relative to the second spline 321.

[0048] like Figure 3 and Figure 4 As shown, both the first friction plate 331 and the second friction plate 332 are annular structures and are arranged coaxially with the output shaft 1. Both the first friction plate 331 and the second friction plate 332 are movable along the axial direction of the output shaft 1.

[0049] When the electromagnetic device 4 is de-energized, the electromagnetic device 4 is oriented towards the second transmission wheel 32 (e.g., Figure 3 The friction assembly 33 is pressed from left to right so that the first friction plate 331 and the second friction plate 332 have axial pressing force. Since the first friction plate 331 and the second friction plate 332 are squeezed against each other, when the first transmission wheel 31 rotates, the first friction plate 331 can drive the second friction plate 332 to rotate synchronously, thereby driving the second transmission wheel 32 to rotate synchronously as well.

[0050] When the electromagnetic device 4 is energized, it releases the axial clamping force between the first friction plate 331 and the second friction plate 332, thus eliminating the squeezing force between them. Therefore, the power transmission between the first drive wheel 31 and the second drive wheel 32 can be cut off, limiting the continued rotation of the second drive wheel 32.

[0051] For example, there are multiple sets of friction components 33, which are arranged sequentially along the axial direction of the output shaft 1, thereby improving the reliability of the transmission device 3.

[0052] like Figures 4 to 7 As shown, the electromagnetic device 4 includes an electromagnetic coil 41, an armature assembly 42, and an elastic element 43. The output shaft 1 is rotatably inserted through the electromagnetic coil 41. The armature assembly 42 is located between the electromagnetic coil 41 and the second transmission wheel 32. The armature assembly 42 slides with the second spline 321 along the axial direction of the output shaft 1. The elastic element 43 is connected to the armature assembly 42 and presses the armature assembly 42 toward the second transmission wheel 32.

[0053] When the electromagnetic coil 41 is de-energized, the elastic element 43 drives the armature assembly 42 to move toward the second transmission wheel 32, so that there is an axial clamping force between the first friction plate 331 and the second friction plate 332. When the electromagnetic coil 41 is energized, the electromagnetic coil 41 drives the armature assembly 42 to move away from the second transmission wheel 32, so as to release the axial clamping force between the first friction plate 331 and the second friction plate 332, and the armature assembly 42 can stop the second transmission wheel 32 from rotating.

[0054] Understandably, since the output shaft 1 rotates through the electromagnetic coil 41, the electromagnetic coil 41 can remain stationary when the first transmission wheel 31 drives the second transmission wheel 32 and the output shaft 1 to rotate. For example, the electromagnetic coil 41 can be connected to a fixed bracket around the electromagnetic clutch brake.

[0055] Because the armature assembly 42 slides along the axial direction of the output shaft 1 with the second spline 321, the armature assembly 42 and the second transmission wheel 32 can rotate and stop synchronously. That is, the armature assembly 42 has a spline surface that mates with the second spline 321, and the armature assembly 42 can move relative to the second spline 321 along the axial direction of the output shaft 1, but the armature assembly 42 cannot rotate relative to the first spline 311.

[0056] When the electromagnetic coil 41 is energized, it drives the armature assembly 42 to move away from the second transmission wheel 32, thereby releasing the axial clamping force between the first friction plate 331 and the second friction plate 332. At this time, the electromagnetic coil 41 can attract the armature assembly 42, thus limiting its continued rotation. Since the armature assembly 42 slides along the axial direction of the output shaft 1 with the second spline 321, the armature assembly 42 stops rotating and simultaneously drives the second transmission wheel 32 to stop rotating, thereby braking the second transmission wheel 32 and the output shaft 1.

[0057] Optionally, such as Figure 4 and Figure 7 As shown, the armature assembly 42 includes an armature 421 and a first pressure block 422. The first pressure block 422 is fixedly installed on the side of the armature 421 facing the friction assembly 33. The inner peripheral wall of the first pressure block 422 is engaged with the second spline 321. The elastic element 43 is connected to the armature 421. When the electromagnetic coil 41 is de-energized, the first pressure block 422 abuts against the friction assembly 33 along the axial direction of the output shaft 1. When the electromagnetic coil 41 is energized, the first pressure block 422 is spaced apart from the friction assembly 33 along the axial direction of the output shaft 1.

[0058] For example, such as Figure 3 and Figure 4As shown, the first pressure block 422 and the armature 421 can be detachably connected by a fourth threaded member 423. There can be multiple fourth threaded members 423, which are arranged at intervals along the circumference of the first pressure block 422.

[0059] Optionally, such as Figures 4 to 7 As shown, the electromagnetic clutch brake also includes a first sleeve 51, which is detachably mounted on the output shaft 1 and abuts against the second transmission wheel 32. An elastic element 43 is disposed between the outer peripheral wall of the first sleeve 51 and the inner peripheral wall of the armature 421. Figure 6 As shown, both the electromagnetic coil 41 and the armature 421 are mounted on the outer periphery of the first sleeve 51. It can be understood that the second transmission wheel 32 is fixedly connected to the output shaft 1 via a flat key, and the first sleeve 51 can axially position the second transmission wheel 32. Since the first sleeve 51 is detachably mounted on the output shaft 1, it is convenient for the operator to remove the second transmission wheel 32 and friction assembly 33 and other parts from the output shaft 1.

[0060] like Figure 6 As shown, the electromagnetic clutch brake also includes a stop block 53, which is disposed between the outer peripheral wall of the first sleeve 51 and the inner peripheral wall of the armature 421, and is fixed relative to the first sleeve 51. One end of the elastic member 43 abuts against the stop block 53, and the other end of the elastic member 43 abuts against the armature 421. It can be understood that when the first sleeve 51 rotates synchronously with the output shaft 1, the stop block 53 will also rotate synchronously with the first sleeve 51. The stop block 53 can axially limit the elastic member 43 to ensure that the elastic member 43 can be compressed when the armature 421 moves to the left.

[0061] For example, the elastic element 43 is a disc spring, which is sleeved on the outer periphery of the first sleeve 51. The outer ring of the disc spring abuts against the armature 421, and the inner ring of the disc spring abuts against the stop block 53. This allows the elastic force applied by the elastic element 43 toward the armature 421 to be more uniform, improving the reliability of the contact between the first pressure block 422 and the friction assembly 33.

[0062] Optionally, such as Figures 5 to 7 As shown, the electromagnetic clutch brake includes a second sleeve 52, which is sleeved on the outside of the first sleeve 51. The electromagnetic device 4 also includes a first bearing 44, which is installed between the outer peripheral wall of the second sleeve 52 and the inner peripheral wall of the electromagnetic coil 41. The position of the second sleeve 52 relative to the armature 421 along the axial direction of the output shaft 1 is adjustable. Since the position of the second sleeve 52 relative to the armature 421 along the axial direction of the output shaft 1 is adjustable, the gap between the electromagnetic coil 41 and the armature 421 can be adjusted to change the braking distance of the electromagnetic clutch brake.

[0063] It is understandable that the first sleeve 51, the second sleeve 52, and the output shaft 1 can rotate synchronously or remain stationary synchronously. Since the first bearing 44 is installed between the outer peripheral wall of the second sleeve 52 and the inner peripheral wall of the electromagnetic coil 41, the electromagnetic coil 41 can remain relatively stationary when the second sleeve 52 rotates.

[0064] For example, such as Figure 6 and Figure 7 As shown, the electromagnetic clutch brake also includes a first retaining ring 54, which is disposed on one side of the first sleeve 51 along the axial direction of the output shaft 1 and is fixedly connected to the first sleeve 51. The first retaining ring 54 is disposed inside the second sleeve 52, and its outer peripheral wall is threadedly connected to the inner peripheral wall of the second sleeve 52, so that the position of the second sleeve 52 relative to the armature 421 along the axial direction of the output shaft 1 is adjustable. Since the outer peripheral wall of the first retaining ring 54 is threadedly connected to the inner peripheral wall of the second sleeve 52, the operator can rotate the second sleeve 52 to adjust its axial position, thereby increasing or decreasing the braking gap of the electromagnetic clutch brake, and thus changing the braking distance of the electromagnetic clutch brake. By adopting the above-described structural arrangement, the electromagnetic clutch brake of this embodiment of the present invention can simplify the braking gap adjustment method and achieve high reliability.

[0065] like Figure 6 and Figure 7 As shown, the inner circumferential wall of the second sleeve 52 has an annular flange 521, which is threadedly engaged with the first retaining ring 54. The electromagnetic clutch brake also includes a second retaining ring 55, which is detachably mounted on the side of the annular flange 521 opposite to the first sleeve 51, and abuts against the annular flange 521. Because the second retaining ring 55 is detachably mounted on the side of the annular flange 521 opposite to the first sleeve 51, and abuts against the annular flange 521, axial movement of the second sleeve 52 can be restricted. Therefore, when it is not necessary to adjust the braking clearance of the electromagnetic clutch brake, the second retaining ring 55 can be stopped on the side of the annular flange 521 opposite to the first sleeve 51. When it is necessary to adjust the braking clearance of the electromagnetic clutch brake, the second retaining ring 55 can be removed. This prevents the problem of the second sleeve 52 becoming loose and altering the braking clearance of the electromagnetic clutch brake.

[0066] For example, such as Figure 6 and Figure 7As shown, the electromagnetic clutch brake also includes a third threaded component 63, which is sequentially threaded through the second retaining ring 55 and the first retaining ring 54 along the axial direction of the output shaft 1. Therefore, the operator can remove the third threaded component 63 to unlock the second retaining ring 55 and the first retaining ring 54. At this time, the operator can rotate the second sleeve 52 to adjust the axial position of the second sleeve 52, thereby increasing or decreasing the braking gap of the electromagnetic clutch brake, and thus changing the braking distance of the electromagnetic clutch brake.

[0067] For example, such as Figure 6 and Figure 7 As shown, the electromagnetic clutch brake also includes a first threaded component 61, which is sequentially threaded through the second retaining ring 55, the first retaining ring 54, and the first sleeve 51 along the axial direction of the output shaft 1. Therefore, the operator can remove the first threaded component 61 to separate the first retaining ring 54, the second retaining ring 55, and the second sleeve 52 from the output shaft 1. At this time, components such as the electromagnetic coil 41 and the elastic element 43 can be removed together, allowing the operator to inspect the electromagnetic coil 41, the elastic element 43, the sealing ring, and other components for damage, thus facilitating timely repair or replacement.

[0068] For example, such as Figure 6 and Figure 7 As shown, the electromagnetic clutch brake also includes a second threaded component 62, which is sequentially threaded through the first sleeve 51 and the output shaft 1 along the axial direction of the output shaft 1. Therefore, the operator can remove the second threaded component 62 to disassemble the entire electromagnetic device 4 from the output shaft 1, so that the operator can check whether the transmission device 3 (first transmission wheel 31, second transmission wheel 32 and friction assembly 33) is damaged, thereby facilitating timely repair or replacement.

[0069] like Figure 3 As shown, the electromagnetic clutch brake also includes a tire 8, which is fixedly mounted on the output shaft 1. It can be understood that the output shaft 1 and the tire 8 can rotate synchronously or remain stationary synchronously.

[0070] For example, the drive wheel 2 can be a pulley.

[0071] Another embodiment of the cableway system of the present invention includes the electromagnetic clutch brake of the present invention.

[0072] According to the cableway system of this utility model, since the electromagnetic device 4 is arranged along the axial direction of the output shaft 1 on one side of the second transmission wheel 32, compared with the scheme of "the electromagnetic device 4 being arranged on both sides of the second transmission wheel 32", the structural size of the electromagnetic clutch brake can be reduced, occupying less space. Furthermore, since the electromagnetic device 4 is arranged along the axial direction of the output shaft 1 on one side of the second transmission wheel 32, it is convenient to disassemble, assemble, and maintain the electromagnetic device 4. On the other hand, when the electromagnetic device 4 is de-energized, it presses the friction assembly 33 towards the second transmission wheel 32, so that the first friction plate 331 and the second friction plate 332 have axial clamping force. Thus, the power of the power wheel 2 can be transmitted along the path of the first transmission wheel 31, the first friction plate 331, the second friction plate 332, the second transmission wheel 32, and the output shaft 1, so that the power wheel 2 drives the output shaft 1 to rotate. When the electromagnetic device 4 is energized, since the electromagnetic device 4 can release the axial clamping force between the first friction plate 331 and the second friction plate 332, it can restrict the rotation of the second transmission wheel 32, thereby braking the output shaft 1. Since the electromagnetic clutch brake of the cableway system is de-energized most of the time, the energy consumption of the electromagnetic clutch brake is reduced.
