Description

Technical Field

[0001] This invention relates to wheel lubrication, and particularly to a dry wheel flange lubrication device and a dry train wheel flange lubrication method. Background Technology

[0002] Wheel lubrication is a crucial aspect of normal train operation. It not only reduces wear on wheels and rails, lowers noise and vibration, but also improves traction and fuel economy. During operation, wheel lubricant forms a protective film between the wheels and rails, reducing friction, lowering energy consumption, extending wheel and rail life, and improving operational efficiency. The selection and use of wheel lubricants are extremely important. Generally, wheel lubricants should possess good lubrication performance, extreme pressure performance, anti-wear properties, oxidation resistance, and noise reduction properties. Furthermore, environmental friendliness, safety, and economic efficiency should also be considered.

[0003] Currently, commonly used wheel lubricants include mineral oil, synthetic oil, and grease. Grease and lubricants can adhere to the surface of wheels and rails for extended periods, offering good water resistance and noise reduction. However, their high cost makes reducing unnecessary consumption and waste during use a crucial issue. For example, current mechanical dry-type wheel flange sliding devices rely on continuous application of lubricant to train wheel flanges, consuming lubricant regardless of operating conditions. Given the long-term, continuous operation of trains and the resulting wear and tear, the consumption is substantial, leading to extremely high material costs. Summary of the Invention

[0004] The purpose of this invention is to provide a dry wheel flange lubrication device and a dry train wheel flange lubrication method to solve the problem of high wear of lubrication blocks in traditional mechanical dry wheel flange lubrication devices.

[0005] One aspect of the present invention provides a dry wheel flange lubrication device, including a channel, a magnetic suction part, and a pressure application part; one end of the channel is open for arranging a lubrication block that abuts against the wheel flange; the magnetic suction part is slidably arranged in the channel; the pressure application part is located on one side of the magnetic suction part and abuts against the magnetic suction part, for continuously applying a thrust toward the magnetic suction part in the direction of the opening.

[0006] This dry wheel flange lubrication device also includes an external electromagnetic part, which is arranged on the side of the channel in the length direction and extends along the channel in the length direction; when energized, the external electromagnetic part attracts the magnetic attraction part so that the magnetic attraction part is fixed in position in the channel; when de-energized, the magnetic attraction part loses its attraction and transmits the thrust of the pressure part to the lubrication block.

[0007] This dry wheel flange lubrication device uses lubrication blocks on the wheel flange to form a protective film of lubricant between the wheel and the rail, thereby reducing friction and wear, improving train traction and economy, and reducing noise and vibration. The external electromagnetic unit is energized to generate attraction on the magnetic attraction unit, which is then fixed to the channel. The entire magnetic attraction unit cannot continue to push the lubricating block forward, and the thrust fails. Because the lubricating block loses the continuous thrust of the thrust spring, it no longer consumes a large amount of lubricant after a short period of wear on the wheel flange, thus reducing excessive consumption and waste of the lubricating block.

[0008] In some feasible embodiments, the magnetic attraction part includes a non-magnetic cover and a magnetic part; one side of the non-magnetic cover abuts against the pressure application part, and the other side is used to abut against the lubrication block; the magnetic part is arranged in a cavity inside the non-magnetic cover, and the magnetic attraction part is connected to the non-magnetic cover through an elastic member, and a gap is left between the magnetic part and the inner wall of the non-magnetic cover near the lubrication block.

[0009] To achieve optimal performance, the magnetic attraction section is designed to consist of a non-magnetic cover and a magnetic section. One side of the non-magnetic cover abuts against the pressure application section, while the other side is used to abut against the lubrication block. In this design, a gap is left between the magnetic section and the non-magnetic cover near the inner wall of the lubrication block to form a buffer space.

[0010] In some feasible embodiments, the magnetic part includes a telescopic control member and a magnetic block. The fixed part of the telescopic control member is connected to the inner wall of the non-magnetic cover away from the lubrication block, and the movable part is movably disposed on the fixed part. The magnetic block is fixedly connected to the movable part and is located on the side of the telescopic control member closer to the outer electromagnetic part. The telescopic control member described above can be pneumatically driven, hydraulically driven, or electrically controlled telescopic components, etc.

[0011] In some feasible embodiments, the telescopic control element is a push-pull electromagnet, the main shaft of which is connected to the side of the non-magnetic cover away from the lubrication block. The aforementioned elastic component can be a spring on the core of the push-pull electromagnet.

[0012] This push-pull electromagnet consists of an electromagnetic coil and an iron core, with the iron core's main shaft connected to the side of the non-magnetic cover furthest from the lubrication block. When current is input to the electromagnetic coil, the magnetic field generated by the electromagnet attracts the iron core to the lubrication block, causing the telescopic control element to retract. When the current is cut off, the magnetic field disappears, the iron core leaves the lubrication block and returns to its original position, thus resetting the telescopic control element by the spring. This push-pull electromagnet features a simple structure and efficient telescopic control capability, making it better suited to the operating environment of this device.

[0013] In some feasible embodiments, the external electromagnetic part is arranged on the lower side of the channel to form a support plate extending along the length of the channel; the magnetic attraction part and the pressure application part are supported above the external electromagnetic part.

[0014] The external electromagnetic unit forms a support plate extending along the length of the channel, while the magnetic attraction unit and the pressure application unit are supported above this external electromagnetic unit. The advantage of this device is that it allows objects to move within the channel by controlling electromagnetic forces.

[0015] In some feasible embodiments, the external electromagnetic part is provided with a limit sensor for detecting the magnetic attraction part at the end facing the wheel. After the limit sensor detects a signal, it can send out a message, such as a prompt or warning message, or it can communicate with a device on the vehicle that has a prompt or warning function, and display the prompt or warning message on the device after detecting the signal.

[0016] Another aspect of the present invention provides a dry train wheel flange lubrication method, employing a dry train wheel flange lubrication device according to the above-mentioned aspect, the dry train wheel flange lubrication method further comprising the following operations:

[0017] Place the lubricating block in the channel, with one end of the lubricating block corresponding to the magnetic attraction part and the other end corresponding to the wheel flange;

[0018] When the wheel needs lubrication, the external electromagnetic part is de-energized, and the magnetic attraction part can be pushed by the pressure part, causing the lubrication block to move towards the wheel so that the lubrication block can be squeezed by the wheel flange to perform continuous lubrication of the wheel flange.

[0019] When the wheel does not require lubrication, the external electromagnetic part is energized, and the magnetic attraction part cannot be pushed by the pressure application part, so that the lubricating block can no longer be pushed to apply pressure to the wheel, so that the lubricating block is no longer squeezed and consumed by the wheel.

[0020] Using dry lubrication blocks instead of traditional lubrication methods can reduce the waste of lubrication materials, thereby reducing operation and maintenance costs and simplifying maintenance.

[0021] In some feasible embodiments, a dry train wheel flange lubrication method further includes the following operations:

[0022] The magnetic attraction part includes a non-magnetic cover with an internal cavity, and the cavity contains a magnetic part that can be attracted by an external electromagnetic part;

[0023] A buffer space is reserved between the magnetic part and the inner wall of the cavity so that when the lubricating block receives reverse displacement pressure from the wheel flange, the magnetic part does not shift during the process of the lubricating block driving the non-magnetic cover to move, so that the magnetic part can maintain the limiting effect on the non-magnetic cover when lubrication is not required.

[0024] In some feasible embodiments, the magnetic part is configured as a controllable mechanism that can extend and retract along the pushing direction of the lubricating block;

[0025] When the lubricating block retracts, the magnetic part retracts towards the pressure-applying part, allowing the magnetic part to retract a predetermined distance, thus maintaining the buffer space at a preset value in the direction of the lubricating block's movement towards the magnetic part. This controllable mechanism can be controlled by methods such as electronic control, pneumatic, or hydraulic transmission. The retraction mentioned above refers to the lubricating block moving towards the pressure-applying part when the vehicle applies reverse compressive pressure.

[0026] In some feasible embodiments, the magnetic part includes a push-pull electromagnet and a magnetic block fixedly connected to the pull electromagnet, wherein the main shaft of the push-pull electromagnet is connected to the side of the non-magnetic cover away from the lubrication block.

[0027] The external electromagnetic part is arranged on the lower side of the channel to form a support plate extending along the length of the channel; the magnetic attraction part and the pressure application part are supported above the external electromagnetic part;

[0028] When the vehicle travels to the area where the wheel flange needs lubrication (such as a curve), the push-pull magnet is de-energized and is in the extended state.

[0029] When the vehicle travels to an area where the wheel rim does not require lubrication (such as a straight section), the push-pull magnet is energized and retracts, causing the magnetic block to move a preset distance from the outer electromagnetic part towards the pressure part. After the push-pull magnet is energized, the outer electromagnetic part is energized within a preset time. The magnetic part is attracted and fixed by the outer electromagnetic part, and pushes the non-magnetic cover back a preset distance. While the magnetic part is retracting, the size of the buffer space in the direction of the lubricating block moving towards the magnetic part is maintained at a preset value.

Therefore, they should not be construed as limiting the scope of protection of this invention.

[0039] Example 1

[0040] Reference Figures 1 to 3A dry wheel flange lubrication device includes a channel 1, a magnetic suction part 2, and a pressure application part 3; one end of the channel 1 is open for arranging a lubrication block 4 that abuts against the wheel flange; the magnetic suction part 2 is slidably arranged in the channel 1; the pressure application part 3 is located on one side of the magnetic suction part 2 and abuts against the magnetic suction part 2, for continuously applying a thrust toward the opening direction to the magnetic suction part 2.

[0041] This dry wheel flange lubrication device also includes an external electromagnetic part 5, which is arranged on the side of the channel 1 along the length direction and extends along the length direction of the channel 1. When energized, the external electromagnetic part 5 attracts the magnetic attraction part 2 to fix the magnetic attraction part 2 in the channel 1. When de-energized, the magnetic attraction part 2 loses its attraction and transmits the thrust of the pressure part 3 to the lubrication block 4.

[0042] This dry wheel flange lubrication device uses a lubrication block 4 on the wheel flange to form a protective film of lubricant between the wheel and the rail, thereby reducing friction and wear, improving the train's traction and economy, and reducing noise and vibration. In this solution, the external electromagnetic part 5 is energized to generate an attraction force on the magnetic attraction part 2. The magnetic attraction part 2 is fixed on the channel 1, and the entire magnetic attraction part 2 can no longer push the lubrication block 4 forward. The thrust is lost, and the lubrication block 4 no longer consumes a large amount of lubricant after a short period of wear on the wheel flange, thus reducing excessive consumption and waste of the lubrication block 4.

[0043] The dry wheel flange lubrication device of the present invention solves the problem of high wear of the lubrication block 4 in traditional mechanical dry wheel flange lubrication devices, while also offering advantages such as economy and environmental friendliness. In the dry wheel flange lubrication device of the present invention, an external electromagnetic unit 5 is used to control the movement of the magnetic suction unit 2. When the external electromagnetic unit 5 is energized, it generates an attractive force with the magnetic suction unit 2, fixing the magnetic suction unit 2 in position within the channel 1. When the external electromagnetic unit 5 is de-energized, the magnetic suction unit 2 loses its attraction and transmits the thrust of the pressure unit 3 to the lubrication block 4. This control method enables automated lubrication between the wheel and rail, improving efficiency and accuracy.

[0044] Combination Figure 2 and Figure 3 The area framed by A in the diagram indicates the installation location of the dry wheel flange lubrication device on the bogie, and the strip-shaped component within the frame is the dry wheel flange lubrication device itself. This channel 1 also serves as the outer casing of the entire device. During installation, this channel 1 can be mounted on the bogie next to the train wheel. Specifically, bolt holes can be provided on channel 1 for bolt connection to the aforementioned bogie.

[0045] At the same time, this control method can also be remotely monitored and controlled through an external control system, realizing intelligent management.

[0046] For example, lubrication is needed when a train turns, but not when it is traveling straight.

[0047] To achieve a technical solution where the switch of the external electromagnetic unit 5 is opened when the train is turning, and remains closed when the train is traveling straight, a sensor can be installed at both the front and rear of the train to detect whether the train is traveling straight or turning.

[0048] Specifically, this sensor can be an inertial sensor based on a gyroscope or accelerometer, or a non-contact sensor based on magnetic field or photoelectric principles. The external electromagnetic unit 5 is connected to the sensor. When the sensor detects a train turning, the external electromagnetic unit 5 automatically disconnects, the magnetic attraction unit 2 releases its obstruction of the pressure application unit 3, and the pressure application unit 3 transmits thrust to the lubrication block 4 for lubrication.

[0049] When the sensor detects that the train is moving straight, the external electromagnetic part 5 automatically closes, and the magnetic attraction part 2 moves a certain distance from the point where it is in the lubrication working state, and then resumes its blocking effect on the pressure application part 3.

[0050] Example 2

[0051] Combination Figure 1 Based on Embodiment 1, the magnetic suction part 2 includes a non-magnetic cover 210 and a magnetic part 220; one side of the non-magnetic cover 210 abuts against the pressure application part 3, and the other side is used to abut against the lubrication block 4; the magnetic part 220 is arranged in the cavity inside the non-magnetic cover 210, and the magnetic suction part 2 is connected to the non-magnetic cover 210 through an elastic member, and a gap is left between the magnetic part 220 and the non-magnetic cover 210 near the inner wall of the lubrication block 4.

[0052] To achieve optimal performance, the magnetic suction unit 2 is designed to consist of a non-magnetic cover 210 and a magnetic part 220. One side of the non-magnetic cover 210 abuts against the pressure application part 3, while the other side is used to abut against the lubrication block 4. In this design, a gap is left between the magnetic part 220 and the non-magnetic cover 210 near the inner wall of the lubrication block 4 to form a buffer space 6.

[0053] This is because the train wheelsets are suspended, and the wheels have an uncertain displacement of about 8mm relative to the bogie to which the lubrication device is fixed. This displacement may suddenly and forcefully compress the lubrication block 4, causing it to break. Therefore, this device is designed with a buffer space 6. When the lubrication block 4 receives reverse displacement compression from the wheel flange, it transmits the pressure to the non-magnetic cover 210. The non-magnetic cover 210 moves towards the pressure application part 3, reducing the buffer space 6 and ultimately transmitting the force to the pressure application part 3, thereby preventing the lubrication block 4 from being forcibly compressed. The aforementioned pressure application part 3 can be a column spring or other compressible and recoverable elastic element.

[0054] It is worth noting that because each lubrication operation consumes the lubricating block 4 and reduces its length, each lubrication operation will cause the pressure part 3 to push the magnetic part 2 a certain distance toward the lubricating block 4, causing the magnetic part 220 to change its position. In order to ensure that after several lubrication operations, when the wheel pushes backward, the entire magnetic part 2 can actively retract as a whole and still leave sufficient buffer space 6 in the non-magnetic cover 210, the following optimization scheme can be implemented.

[0055] Based on this embodiment, further optimization is possible. For example, the magnetic part 220 includes a telescopic control member 221 and a magnetic block 222. The fixed part of the telescopic control member 221 is connected to the inner wall of the non-magnetic cover 210 away from the lubrication block 4, and the movable part is movably disposed on the fixed part. The magnetic block 222 is fixedly connected to the movable part, and the magnetic block 222 is located on the side of the telescopic control member 221 near the outer electromagnetic part 5. The telescopic control member 221 can be pneumatically driven, hydraulically driven, or electrically controlled telescopic component, etc.

[0056] The telescopic control component 221 mentioned in this invention can be driven by pneumatic or hydraulic pressure, or an electrically controlled telescopic component can be used.

[0057] For example, a piston and cylinder structure can be used to implement a pneumatically driven telescopic control member 221. In this design, the fixed part of the telescopic control member 221 is connected to a portion of the non-magnetic cover 210, while the movable part can move freely on the fixed part. When gas enters the cylinder, the piston moves outward, separating the fixed part and the movable part.

[0058] When the gas is expelled, the piston returns to its original position, pushing the fixed and movable parts back together. Similarly, the hydraulically driven telescopic control member 221 can be implemented using a hydraulic cylinder structure. In this design, the piston of the hydraulic cylinder moves outward under the pressure of hydraulic oil, separating the fixed and movable parts of the telescopic control member 221. When the hydraulic oil is expelled, the piston returns to its original position, pushing the fixed and movable parts back together. Alternatively, the electrically controlled telescopic component can be implemented using a motor and gear structure. In this design, the motor controls the rotation of the gears, separating or pushing the fixed and movable parts of the telescopic control member 221 back together.

[0059] Preferably, in this embodiment, the telescopic control member 221 is a push-pull electromagnet, and the main shaft of the push-pull electromagnet is connected to the side of the non-magnetic cover 210 away from the lubrication block 4.

[0060] This push-pull electromagnet consists of an electromagnetic coil and an iron core, with the iron core's main shaft connected to the side of the non-magnetic cover 210 away from the lubrication block 4. When current is input to the electromagnetic coil, the magnetic field generated by the electromagnet attracts the iron core into the coil, thus pushing the magnetic block 222 connected to the iron core away from the lubrication block 4. When the current is disconnected, the electromagnet no longer generates a magnetic field, the iron core springs back to its original position, and the magnetic block 222 also returns. In this way, the push-pull electromagnet can control the position of the magnetic block 222.

[0061] The magnetic block 222 can be threaded onto the push-pull electromagnet. This connection method allows for a tight bond between the magnetic block 222 and the iron core, thereby improving force transmission and accuracy. Simultaneously, this connection method also allows for easy replacement and adjustment of the magnetic block 222 to accommodate different lubrication blocks 4 and wheel-rail distances. In addition, other connection methods can be used, such as welding, bonding, etc.

[0062] Example 3

[0063] Combination Figure 1 Based on any of the above schemes, the external electromagnetic part 5 is arranged on the lower side of the channel 1 to form a support plate extending along the length of the channel 1; the magnetic attraction part 2 and the pressure application part 3 are supported above the external electromagnetic part 5.

[0064] The external electromagnetic unit 5 forms a support plate extending along the length of the channel 1, and the magnetic attraction unit 2 and the pressure application unit 3 are supported above this external electromagnetic unit 5. The advantage of this arrangement is that it allows objects to move within the channel 1 by controlling electromagnetic force. The presence of the external electromagnetic unit 5 supports the magnetic attraction unit 2 and the pressure application unit 3, enabling them to operate more smoothly. In this embodiment, the length of the channel 1 is fully utilized, and the arrangement is placed at the bottom of the channel 1, occupying minimal space. This construction improves production efficiency and reduces the production cost of the channel 1.

[0065] Based on this embodiment, further optimizations can be made, such as providing a limit sensor 7 for detecting the magnetic attraction part 2 at the end of the external electromagnetic part 5 facing the wheel; after the limit sensor 7 detects the signal, it can send out a message, such as a prompt message or warning message, or communicate with a device on the vehicle that has a prompt or warning function, and display or show the prompt or warning message on the device after detecting the signal.

[0066] As the aforementioned lubricating block 4 is consumed, the aforementioned magnetic suction part 2 will gradually move towards the wheel. When it reaches a certain position, an alarm will remind the staff to replace the lubricating block 4.

[0067] When the magnetic suction part 2 contacts the limit sensor 7, a switch can be used to detect its contact state. This switch can be a mechanical switch, such as a common microswitch, or a photoelectric sensor or other type of sensor. When the switch detects contact with the magnetic suction part 2, such as when the magnetic suction part 2 touches the microswitch or the photoelectric sensor detects that the magnetic suction part 2 has reached a designated position, a circuit is triggered, which sends a signal to an alarm. The alarm can be a sound alarm, a flashing light alarm, or other type of alarm to notify personnel in case of malfunction. Of course, to ensure reliability, multiple sensors and multiple alarms can be used in the system so that a backup component can take over if one component fails. This technical solution can improve the reliability and stability of the entire device.

[0068] According to the above embodiment, a dry train wheel flange lubrication method can be used to lubricate the train wheel flange. The dry train wheel flange lubrication method further includes the following operations:

[0069] Place the lubricating block 4 in the channel 1, with one end of the lubricating block 4 corresponding to the magnetic suction part 2 and the other end corresponding to the wheel flange;

[0070] When the wheel needs lubrication, the external electromagnetic part 5 is de-energized, and the magnetic attraction part 2 can be pushed by the pressure part 3, so that the lubrication block 4 moves towards the wheel, so that the lubrication block 4 receives the force of squeezing the wheel flange, and performs continuous lubrication of the wheel flange.

[0071] When the wheel does not require lubrication, the external electromagnetic part 5 is energized, the magnetic attraction part 2 cannot be pushed by the pressure application part 3, and the lubrication block 4 cannot continue to apply pressure to the wheel, so that the lubrication block 4 will no longer be consumed by the wheel under compression after a short period of wheel rim wear.

[0072] Using dry lubrication blocks 4 instead of traditional lubrication methods can reduce the waste of lubrication materials, thereby reducing operation and maintenance costs and simplifying maintenance.

[0073] This dry train wheel flange lubrication method also includes the following operations:

[0074] The magnetic suction unit 2 includes a non-magnetic cover 210 with an internal cavity, and the cavity contains a magnetic part 220 that can be attracted by the external electromagnetic part 5.

[0075] A buffer space 6 is reserved between the magnetic part 220 and the inner wall of the cavity so that when the lubricating block 4 receives the reverse displacement pressure from the wheel flange, the magnetic part 220 does not shift during the process of the lubricating block 4 driving the non-magnetic cover 210 to move, so that the magnetic part 220 can maintain the limiting effect on the non-magnetic cover 210 when lubrication is not required.

[0076] The lubricating block 4 is designed to be installed on the wheel rim, i.e., correspondingly set using the aforementioned channel 1. The geometry of the lubricating block 4 can be circular, elliptical, or other shapes. The size and shape of the lubricating block 4 can be adjusted according to the size and shape of the wheel rim.

[0077] A magnetic suction part 2 is installed inside the channel 1. This magnetic suction part 2 includes a non-magnetic cover 210 with an internal cavity, and the cavity contains a magnetic part 220 that can be attracted by the external electromagnetic part 5.

[0078] A buffer space 6 is reserved between the magnetic part 220 and the inner wall of the cavity so that when the lubricating block 4 receives the reverse displacement pressure from the wheel flange, the magnetic part 220 does not shift during the movement of the non-magnetic cover 210 driven by the lubricating block 4. The magnetic part 220 can still maintain the limiting effect on the non-magnetic cover 210 when the lubricating block 4 is retracted.

[0079] The magnetic part 220 is configured as a controllable mechanism that can extend and retract along the pushing direction of the lubricating block 4.

[0080] When the lubricating block 4 retracts, the magnetic part 220 retracts towards the pressure part 3, allowing the magnetic part 220 to retract a predetermined distance, thus maintaining the buffer space 6 at a preset value in the direction of movement of the lubricating block 4 towards the magnetic part 220. This controllable mechanism can be controlled by methods such as electronic control, pneumatic, or hydraulic transmission. The retraction refers to the movement of the lubricating block 4 towards the pressure part 3 when the vehicle applies reverse compressive pressure.

[0081] The magnetic part 220 includes a push-pull electromagnet and a magnetic block 222 fixedly connected to the pull electromagnet. The main shaft of the push-pull electromagnet is connected to the side of the non-magnetic cover 210 away from the lubrication block 4. The outer electromagnetic part 5 is arranged on the lower side of the channel 1 to form a support plate extending along the length of the channel 1. The magnetic attraction part 2 and the pressure application part 3 are supported above the outer electromagnetic part 5.

[0082] When the vehicle travels to the area where the wheel flange needs lubrication, the push-pull magnet is de-energized and is in an extended state.

[0083] When the vehicle travels to the section where the wheel rim does not require lubrication, the push-pull magnet is energized and retracts, causing the magnetic block 222 to move a preset distance from the outer electromagnetic part 5 towards the pressure part 3. After the push-pull magnet is energized, the outer electromagnetic part 5 is energized within a preset time, and the magnetic part 220 is attracted and fixed by the outer electromagnetic part 5. While the magnetic part 220 is retracting, the size of the buffer space 6 in the direction of movement of the lubrication block 4 towards the magnetic part 220 is maintained at a preset value.

[0084] Specifically, the aforementioned magnetic block 222 can be made of magnetic metal, and during reverse engineering, it can be made of magnetic metal. Figure 1The push-pull magnet device shown has a push-pull magnet (4mm, thrust value 50N) fixed to a magnetic metal. The main body of the push-pull magnet is integrated with the magnetic metal. The iron core of the push-pull magnet and the non-magnetic cover 210 form a limitable stretching structure. The horizontal thrust between the magnetic metal and the outer electromagnetic part 5 is set to 60N.

[0085] When using the aforementioned dry wheel flange lubrication device, the working mode of this method is as follows:

[0086] Lubrication mode: The push-pull magnet is not charged, and the magnetic attraction part 2 on the external electromagnetic part 5 is in a free and movable state. In this state, the pressure part 3 (spring) pushes the magnetic attraction part 2 to press against the lubrication block 4, and the lubrication block 4 performs lubrication work.

[0087] Standby mode: When the push-pull magnet is powered on, the internal iron core of the push-pull magnet moves relative to the cavity of the push-pull magnet. Figure 1 The magnet moves to the right (at this time, the movement is the magnetic part 220 inside the non-magnetic cover 210. Since the lubricating block 4 and the wheel rim are in contact, the non-magnetic cover 210 cannot move to the right). The entire push-pull magnet and the magnetic metal move 4mm to the left relative to the outer electromagnetic part 5. The 40N spring on the push-pull magnet is compressed. In this solution, the spring pressure generated by this stroke is set to a maximum of no more than 45N.

[0088] After the push-pull magnet is energized, the external electromagnetic part 5 is energized within 1 second, and the magnetic metal is attracted, thus fixing the entire magnetic part 220 in position.

[0089] After the external electromagnetic unit 5 is powered on, the push-pull magnet is de-energized. The 40N spring on the push-pull magnet (at this time, the spring force is between 40N and 45N) pushes the non-magnetic metal to overcome the spring pressure (30N) and move 4mm to the left, so as to achieve the purpose of retracting the non-magnetic cover 210 by 4mm.
