When the electromagnetic device is powered, the electromagnetic device can release the axial compression force between the first friction plate and the second friction plate, so as to limit the rotation of the second transmission wheel and brake the output shaft.

[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 embodiment of the invention 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 loses power, the electromagnetic device 4 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 compression force. When the electromagnetic device 4 is powered, the electromagnetic device 4 can release the axial compression force between the first friction plate 331 and the second friction plate 332, and stop the rotation of the second transmission wheel 32.

[0042] The electromagnetic clutch brake according to the embodiment of the present application can reduce the structural size of the electromagnetic clutch brake, occupy less space, and facilitate the disassembly and maintenance of the electromagnetic device 4, because the electromagnetic device 4 is arranged on one side of the second transmission wheel 32 along the axial direction of the output shaft 1.

[0043] On the other hand, when the electromagnetic device 4 loses power, the electromagnetic device 4 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 compression 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 output shaft 1 is driven to rotate by the power wheel 2. When the electromagnetic device 4 is powered, the electromagnetic device 4 can release the axial compression force between the first friction plate 331 and the second friction plate 332, so as to limit the rotation of the second transmission wheel 32 and brake the output shaft 1. Because the electromagnetic clutch brake is in a power loss state most of the time, the energy consumption of the electromagnetic clutch brake is reduced.

[0044] Therefore, the electromagnetic clutch brake according to the embodiment of the present application can simplify the structure, occupy less space, facilitate the disassembly and maintenance of the electromagnetic clutch brake by the operator, and reduce the energy consumption.

[0045] In the related art, as shown in Figure 1 The electromagnetic device of the electromagnetic clutch brake is divided into the brake 1' and the clutch 2', and the brake 1' and the clutch 2' are arranged on both sides of the transmission wheel 3', so that the above structure leads to a large axial size of the electromagnetic clutch brake, and is not convenient for the operator to disassemble and maintain the electromagnetic device.

[0046] The electromagnetic clutch brake according to the embodiment of the present application can simplify the arrangement structure of the electromagnetic device 4, reduce the space occupation, and facilitate the disassembly and maintenance of the electromagnetic device 4 by the operator, because the electromagnetic device 4 is arranged on one side of the second transmission wheel 32 along the axial direction of the output shaft 1.

[0047] As shown in 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 member 43 drives the armature assembly 42 to move towards the direction of the second transmission wheel 32, so that the axial pressing force between the first friction plate 331 and the second friction plate 332 is generated. 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 that the axial pressing force between the first friction plate 331 and the second friction plate 332 is released, and the armature assembly 42 can stop the rotation of the second transmission wheel 32.

[0054] It can be understood that, since the output shaft 1 is rotatable through the electromagnetic coil 41, when the first transmission wheel 31 drives the second transmission wheel 32 and the output shaft 1 to rotate, the electromagnetic coil 41 can remain stationary. For example, the electromagnetic coil 41 can be connected with a fixed support around the electromagnetic clutch-brake.

[0055] Since the armature assembly 42 is in sliding fit with the second spline 321 along the axial direction of the output shaft 1, the armature assembly 42 and the second transmission wheel 32 can rotate synchronously and stop synchronously. That is, the armature assembly 42 has a spline face matched 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, the electromagnetic coil 41 drives the armature assembly 42 to move away from the second transmission wheel 32, so that the axial pressing force between the first friction plate 331 and the second friction plate 332 is released. At this time, the electromagnetic coil 41 can attract the armature assembly 42 to limit the armature assembly 42 from continuing to rotate. Since the armature assembly 42 is in sliding fit with the second spline 321 along the axial direction of the output shaft 1, the armature assembly 42 stops rotating at the same time, and the second transmission wheel 32 also stops rotating, so that the second transmission wheel 32 and the output shaft 1 can be braked.

[0057] Alternatively, as shown in Figure 4 and Figure 7 , the armature assembly 42 comprises an armature 421 and a first pressing block 422, the first pressing block 422 is fixedly installed on the side of the armature 421 facing the friction assembly 33, the inner peripheral wall of the first pressing block 422 is matched with the second spline 321, and the elastic member 43 is connected with the armature 421. When the electromagnetic coil 41 is de-energized, the first pressing 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 pressing block 422 is spaced apart from the friction assembly 33 along the axial direction of the output shaft 1.

[0058] Exemplarily, as shown in Figure 3 and Figure 4As shown, the first pressing block 422 and the armature 421 can be detachably connected through fourth threaded members 423, and the fourth threaded members 423 can be multiple and arranged at intervals along the circumference of the first pressing block 422.

[0059] Optionally, as shown, Figures 4 to 7 As shown, the electromagnetic clutch brake further comprises a first sleeve 51, which is detachably mounted on the output shaft 1 and abuts against the second transmission wheel 32, and the elastic member 43 is arranged between the outer circumferential wall of the first sleeve 51 and the inner circumferential wall of the armature 421. As shown, Figure 6 As shown, the electromagnetic coil 41 and the armature 421 are both mounted on the outer circumferential side of the first sleeve 51. It can be understood that the second transmission wheel 32 is fixedly connected with the output shaft 1 through 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 dismount the second transmission wheel 32 and the friction assembly 33 and other parts from the output shaft 1.

[0060] As shown, Figure 6 As shown, the electromagnetic clutch brake further comprises a stop block 53, which is arranged between the outer circumferential wall of the first sleeve 51 and the inner circumferential wall of the armature 421 and is fixed opposite 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 also rotates synchronously with the first sleeve 51. The stop block 53 can axially position the elastic member 43 to ensure that the elastic member 43 can be compressed when the armature 421 moves to the left.

[0061] Exemplarily, the elastic member 43 is a disc spring, which is sleeved on the outer circumferential side 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. In this way, the elastic force exerted by the elastic member 43 on the armature 421 is more uniform, and the reliability of the contact between the first pressing block 422 and the friction assembly 33 is improved.

[0062] Optionally, as shown, Figures 5 to 7 As shown, the electromagnetic clutch brake comprises a second sleeve 52, which is sleeved on the outside of the first sleeve 51, and the electromagnetic device 4 further comprises a first bearing 44, which is mounted between the outer circumferential wall of the second sleeve 52 and the inner circumferential 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 can be understood that the first sleeve 51, the second sleeve 52 and the output shaft 1 can rotate synchronously or be stationary synchronously. Since the first bearing 44 is installed between the outer circumferential wall of the second sleeve 52 and the inner circumferential wall of the electromagnetic coil 41, when the second sleeve 52 rotates, the electromagnetic coil 41 can remain relatively stationary.

[0064] As shown in Figs. 1 and 2, the electromagnetic clutch brake further comprises a first sleeve 51, which is arranged on the output shaft 1 and is fixedly connected with the output shaft 1, and the first sleeve 51 is arranged in the second sleeve 52. Figure 6 and Figure 7 As shown in Figs. 1 and 2, the electromagnetic clutch brake further comprises a first sleeve 51, which is arranged on the output shaft 1 and is fixedly connected with the output shaft 1, and the first sleeve 51 is arranged in the second sleeve 52.

[0065] As shown in Figs. 1 and 2, the electromagnetic clutch brake further comprises a first sleeve 51, which is arranged on the output shaft 1 and is fixedly connected with the output shaft 1, and the first sleeve 51 is arranged in the second sleeve 52. Figure 6 and Figure 7 As shown in Figs. 1 and 2, the electromagnetic clutch brake further comprises a first sleeve 51, which is arranged on the output shaft 1 and is fixedly connected with the output shaft 1, and the first sleeve 51 is arranged in the second sleeve 52.

[0066] As shown in Figs. 1 and 2, the electromagnetic clutch brake further comprises a first sleeve 51, which is arranged on the output shaft 1 and is fixedly connected with the output shaft 1, and the first sleeve 51 is arranged in the second sleeve 52. Figure 6 and Figure 7As shown in

[0070] As shown in

[0071] Another embodiment of the cableway system of the present application comprises the electromagnetic clutch brake of the present application.

[0072] According to the cableway system of the embodiment of the present application, 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, compared with the scheme that the electromagnetic device 4 is arranged on both sides of the second transmission wheel 32, the structural size of the electromagnetic clutch brake can be reduced, the occupied space is smaller, and 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, the electromagnetic device 4 can be conveniently disassembled and overhauled. On the other hand, when the electromagnetic device 4 loses power, the electromagnetic device 4 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 compression force, so that the power of the driving 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 driving wheel 2 drives the output shaft 1 to rotate. When the electromagnetic device 4 is powered, since the electromagnetic device 4 can release the axial compression force between the first friction plate 331 and the second friction plate 332, the rotation of the second transmission wheel 32 can be limited to brake the output shaft 1. Since the electromagnetic clutch brake of the cableway system is in a power-off state most of the time, the energy consumption of the electromagnetic clutch brake is reduced.
