Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle components, in particular to a dual-action centrifugal bead structure of a motorcycle active disc. Background Art

[0002] A motorcycle is a two-wheeled or three-wheeled vehicle driven by a gasoline engine and steered by handlebars. It is light, flexible and fast. In the motorcycle transmission system, there is a cylindrical centrifugal ball. The centrifugal characteristics of the swing are used. After the engine crankshaft drives the active disc, the centrifugal ball pushes the pressure plate to change the speed of the rotation system.

[0003] For example, a dual-action centrifugal bead for a motorcycle active disc, with authorization publication number CN203516661U, comprises two cylindrical shells of equal size, with a connecting shaft located between the two shells. Half of each shell is counterweighted, and the other half is hollow. The centrifugal bead is eccentric. While the aforementioned document demonstrates that the housing of the device can be made of lightweight titanium alloy or carbon fiber, achieving a significant eccentric effect and being wear-resistant and durable, the device has a simple structure and is easy to manufacture. However, during operation, the dual-action centrifugal bead, due to the constant contact between the centrifugal bead, the centrifugal support, and the active disc, can become damaged and reduce in size after prolonged contact, necessitating replacement. However, the centrifugal bead lacks any internal replacement mechanism to facilitate quick replacement of the centrifugal bead, making it inconvenient to replace the centrifugal bead within the active disc. Furthermore, the dual-action centrifugal bead lacks any internal lubrication mechanism to lubricate the centrifugal bead during use, accelerating damage to the centrifugal bead and reducing its service life. Summary of the Invention

[0004] The utility model aims to solve the problem of inconvenience in replacing the centrifugal beads inside the motorcycle driving disk and shortening the service life of the centrifugal beads inside the motorcycle driving disk, and proposes a dual-action centrifugal bead structure for the motorcycle driving disk.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A dual-action centrifugal bead structure with an active disc for a motorcycle is designed, comprising a main shaft and a first sleeve. The first sleeve is fixedly connected to the outer wall of the main shaft, the surface of the first sleeve is in contact with a belt, the outer wall of the first sleeve is mounted with an active disc, the outer wall of the first sleeve is mounted with a driven disc, the outer wall of the main shaft is in contact with the inner wall of the second sleeve, a replacement device is provided on the outside of the second sleeve, and a lubrication device is provided on the inside of the active disc.

[0007] Preferably, the replacement device includes a nut and a threaded column, the nut fits against the outer wall of the second sleeve, the nut is threadedly connected to the threaded column, the end of the threaded column is fixedly connected to the outer wall of the connecting column, and the end of the connecting column is fixedly connected to the outer wall of the connecting plate.

[0008] Preferably, the connecting plate is in contact with the outer wall of the second sleeve, and the connecting column is in clearance fit with the main shaft.

[0009] Preferably, the outer wall of the second sleeve is fixedly connected to the centrifugal support, and the centrifugal support is in contact with the centrifugal beads.

[0010] Preferably, the lubricating device includes a block and an opening, the block fits with the opening, the opening is opened inside the active disk, the channel is opened inside the active disk, and the opening and the channel are connected.

[0011] Preferably, the channel is connected to a through hole, and the through hole is provided inside the active disk.

[0012] The utility model proposes a dual-action centrifugal bead structure for an active disk of a motorcycle, which has the beneficial effects of rotating the nut in the replacement device on the threaded column and leaving the threaded column. At this time, the staff pulls the connecting plate, and the connecting plate drives the connecting column to move, and the connecting column drives the threaded column to move, and the connecting column and the threaded column are moved out of the second sleeve and the interior of the main shaft. The staff moves the second sleeve, and the second sleeve drives the centrifugal bracket to move, and the centrifugal bracket is separated from the active disk, and the centrifugal beads are removed, and new centrifugal beads are put in, and the centrifugal bracket is moved to the original position, and the connecting column and the threaded column are inserted into the interior of the second sleeve and the main shaft, and the nut is rotated in the opposite direction to fix the second sleeve to complete the replacement of the centrifugal beads. When the dual-action centrifugal bead structure of the active disk of the motorcycle is set up, the centrifugal beads can be quickly replaced by the replacement device, and the centrifugal beads inside the active disk of the motorcycle are conveniently replaced.

[0013] By pulling out the block in the lubricating device, the staff pours the lubricating oil into the inside of the opening, the lubricating oil flows into the channel through the opening, and then enters the through hole through the channel, and finally the lubricating oil flows into the surface of the centrifugal beads through the through hole to lubricate the centrifugal beads. When the dual-action centrifugal beads of the motorcycle active disk are used, the centrifugal beads can be lubricated by the lubricating device, the damage rate of the centrifugal beads is slowed down, and the service life of the centrifugal beads inside the motorcycle active disk is increased.

When the motorcycle is in a medium-speed state, the active disc 3 is displaced a certain distance, and at this time, the counterweight side of the centrifugal bead is at the lower part of the active disc 3; when the motorcycle is in a high-speed state, the active disc 3 is displaced a maximum distance, and at this time, the counterweight side of the centrifugal bead is on the outside of the active disc 3. At this time, the centrifugal force is greater and fuel-efficient.

The end of the threaded column 602 is fixedly connected to the outer wall of the connecting column 603. The end of the connecting column 603 is fixedly connected to the outer wall of the connecting plate 604. The connecting plate 604 drives the connecting column 603 to move, and the connecting column 603 drives the threaded column 602 to move, so that the connecting column 603 and the threaded column 603 are moved. After exiting the second sleeve 9 and the spindle 1, the staff moves the second sleeve 9, which drives the centrifugal support 10 to move. The centrifugal support 10 is separated from the active disk 3, and the centrifugal beads 11 are removed. The connecting plate 604 is fitted with the outer wall of the second sleeve 9, and the connecting column 603 is loosely fitted with the spindle 1. New centrifugal beads 11 are placed in, and the centrifugal support 10 is moved to its original position. The connecting column 603 and the threaded column 602 are inserted into the second sleeve 9 and the spindle 1. The nut 601 is rotated in the opposite direction to fix the second sleeve 9, and the centrifugal beads 11 are replaced.

[0024] The nut 601 in the replacement device 6 is rotated on the threaded column 602 and leaves the threaded column 602. At this time, the staff pulls the connecting plate 601, and the connecting plate 604 drives the connecting column 603 to move, and the connecting column 603 drives the threaded column 602 to move, and the connecting column 603 and the threaded column 603 are moved out of the second sleeve 9 and the interior of the main shaft 1. The staff moves the second sleeve 9, and the second sleeve 9 drives the centrifugal bracket 10 to move. The centrifugal bracket 10 is separated from the active disk 3, the centrifugal beads 11 are removed, and new centrifugal beads 11 are put in. The centrifugal bracket 10 is moved to its original position, and the connecting column 603 and the threaded column 602 are inserted into the interior of the second sleeve 9 and the main shaft 1. The nut 601 is rotated in the opposite direction to fix the second sleeve 9 to complete the replacement of the centrifugal beads 11. When the dual-action centrifugal beads of the motorcycle active disk are set to work, the centrifugal beads 11 can be quickly replaced by the replacement device 6, which is convenient for replacing the centrifugal beads inside the motorcycle active disk.

[0025] Refer to the attached Figure 1-6 : In this embodiment, the outer wall of the second sleeve 9 is fixedly connected to the centrifugal support 10, the centrifugal support 10 is fitted with the centrifugal beads 11, the lubricating device 7 includes a block 701 and an opening 702, the block 701 is fitted with the opening 702, the staff pours the lubricating oil into the interior of the opening 702, the lubricating oil flows into the channel 703 through the opening 702, the opening 702 is opened inside the active disk 3, the channel 703 is opened inside the active disk 3, the opening 702 and the channel 703 are interconnected, the channel 703 is interconnected with the through hole 8, and then enters the through hole 8 through the channel 703, and finally the lubricating oil flows into the surface of the centrifugal beads 11 through the through hole 8 to lubricate the centrifugal beads 11, and the through hole 8 is opened inside the active disk 3;

[0026] By pulling out the block 701 in the lubricating device 7, the staff pours the lubricating oil into the inside of the opening 702, and the lubricating oil flows into the channel 703 through the opening 702, and then enters the through hole 8 through the channel 703. Finally, the lubricating oil flows into the surface of the centrifugal beads 11 through the through hole 8 to lubricate the centrifugal beads 11. When the dual-action centrifugal beads of the motorcycle active disk are used, the centrifugal beads 11 can be lubricated by the lubricating device 7, the damage rate of the centrifugal beads is slowed down, and the service life of the centrifugal beads inside the motorcycle active disk is increased.

[0027] Working principle:

[0028] When the motorcycle's driving disc dual-action centrifugal bead structure changes speed, the external motorcycle generator first drives the main shaft 1 to rotate. When the motorcycle is in a medium-speed state, the driving disc 3 is displaced a certain distance. At this time, the counterweight side of the centrifugal bead is at the bottom of the driving disc 3. When the motorcycle is in a high-speed state, the driving disc 3 is displaced a maximum distance. At this time, the counterweight side of the centrifugal bead is on the outside of the driving disc 3. At this time, the centrifugal force is greater and fuel is saved. When the centrifugal bead 11 needs to be replaced, the staff rotates the replacement device 6 to replace the centrifugal bead 11. When the centrifugal bead 11 needs to be lubricated, the staff pours lubricating oil into the interior of the lubrication device 7 to lubricate the centrifugal bead 11. The specific replacement process and lubrication process are as follows:

[0029] Replacement process:

[0030] The staff member uses an external tool to rotate the nut 601, and the nut 601 rotates on the threaded column 602 and leaves the threaded column 602. At this time, the staff member pulls the connecting plate 601, and the connecting plate 604 drives the connecting column 603 to move, and the connecting column 603 drives the threaded column 602 to move, and the connecting column 603 and the threaded column 603 are moved out of the second sleeve 9 and the main shaft 1. The staff member moves the second sleeve 9, and the second sleeve 9 drives the centrifugal bracket 10 to move. The centrifugal bracket 10 is separated from the active disk 3, and the centrifugal beads 11 are removed. New centrifugal beads 11 are placed, and the centrifugal bracket 10 is moved to its original position. The connecting column 603 and the threaded column 602 are inserted into the second sleeve 9 and the main shaft 1, and the nut 601 is rotated in the opposite direction to fix the second sleeve 9, and the replacement of the centrifugal beads 11 is completed.

[0031] Lubrication process:

[0032] The staff pulls out the block 701 and pours lubricating oil into the inside of the opening 702. The lubricating oil flows into the channel 703 through the opening 702, and then enters the through hole 8 through the channel 703. Finally, the lubricating oil flows into the surface of the centrifugal beads 11 through the through hole 8 to lubricate the centrifugal beads 11. After completion, the staff reinserts the block 701 into the opening 702. Example
