Description

Title of the invention: New synchronous wheel structure system technical field

[0001] The present invention relates to the technical field of bicycles and electric bicycles, more particularly to a new synchronous wheel structure system. Technical background

[0002] A synchronous belt pulley generally refers to a device made of a material such as steel, aluminum alloy, cast iron, brass, etc., with a circular hole, a D-shaped hole, a conical hole, etc. The synchronous belt and pulley drive consists of a closed circular rubber belt with equally spaced teeth on its inner surface and corresponding pulleys. It is very common in the field of bicycles and electric bicycles.

[0003] The Chinese patent disclosed under publication number CN217381515U reveals a synchronous wheel structure device comprising a main synchronous wheel body. The lateral surface of the main body of the synchronous wheel is provided with a mounting groove, the inside of the mounting groove is provided with an inner lining, one side of the mounting groove is provided with a groove, the inside of the groove is provided with a hole lining, the hole lining has a truncated conical structure, a void space is provided inside the hole lining, and the hole lining is fixed to the inner lining.The outer surface of the hole liner has openings around its periphery, and a passage opening is provided near the end of the inner liner. Holes are arranged equidistantly in a ring shape on the inner surface of the inner liner. Thanks to the toothed ring, the inner liner is directly attached to the main body with a bolt, ensuring a tighter and more stable installation of the inner liner, thus preventing tooth slippage during use. This simple structure solves the high cost problems for users due to misalignment during the installation of synchronized gears, the materials used in assembling multiple parts, and improves processing efficiency.

[0004] However, despite the synchronous wheel structure proposed in the aforementioned technical solution, several drawbacks still exist in its practical use. For example, during daily use, sand and stones easily accumulate on the synchronous wheel, making them difficult to remove and potentially affecting its operation. Furthermore, once the belt is connected, it is easy for it to detach or slip during operation. operation, which results in impractical use. Contents of the invention

[0005] The object of the present invention is to propose a new technical solution with a new synchronous wheel structure system intended to resolve the disadvantages of the prior art.

[0006] To this end, the invention relates to a new synchronous wheel structure system, comprising a rear synchronous wheel housing, a drive belt, and a front synchronous wheel. The exterior of the rear synchronous wheel housing is provided with a sand discharge groove, one side of which is beveled. Both sides of the rear synchronous wheel housing are fitted with steel balls. The middle of the rear synchronous wheel housing is provided with a cover with inverted teeth, which is hinged to the rear synchronous wheel housing. Both ends of the cover with inverted teeth are provided with claw-shaped grooves. A retaining spring is disposed on one side of the cover with inverted teeth. Retaining claws are present between the retaining spring and the claw-shaped grooves. The end of the cover with inverted teeth is fitted with a locking ring, which is connected to the cover with inverted teeth by a thread.The edges of the rear synchronous wheel housing are fitted with a drive belt, and one end of the drive belt is fitted with the front synchronous wheel.

[0007] Advantageously, the outside of the rear synchronous wheel housing is hollow, and the sand discharge groove is uniformly distributed in a ring shape relative to the central axis of the rear synchronous wheel housing.

[0008] Advantageously, the position of the bevel corresponds to that of the sand discharge groove, and the bevel is uniformly distributed in the shape of a ring with respect to the central axis of the reverse-toothed cover.

[0009] Advantageously, the central axis of the reverse-toothed cover coincides with the central axis of the rear synchronous wheel housing, and there is an articulated link between the rear synchronous wheel housing and the steel balls.

[0010] Advantageously, the claw-shaped grooves are symmetrical with respect to the central axis of the reverse-toothed cover, and there is an articulated connection between the claw-shaped grooves and the retaining claws.

[0011] Advantageously, the central axis of the locking ring coincides with the central axis of the reverse-toothed cover.

[0012] Compared to the prior art, this advantage of the present system lies in the fact that it features a hollow structure on the outer side of the rear synchronous wheel with a sand discharge groove and a corresponding bevel. When the synchronous wheel is in motion, sludge and sand can be quickly evacuated from the toothed grooves, thus increasing the service life of the synchronous belt and the synchronous wheel. In addition, the rear synchronous wheel housing is arranged so that the toothed retaining edges are offset and alternate on each side, which allows the belt to be efficiently and correctly introduced into the teeth of the pulley during the rotation of the belt and pulley, thus preventing belt slippage and incorrect drive, improving the practicality of this device.

Professionals in the field may interpret these terms in the specific context of the present invention according to the particular circumstances.

[0023] Please refer to Figures 1 to 6. The present invention relates to a new synchronous wheel structure system, comprising a rear synchronous wheel housing 1 and a reverse-toothed cover 5. The rear synchronous wheel housing 1 has a sand discharge groove 2 on the outside, and a bevel 3 is located on one side of the sand discharge groove 2. The rear synchronous wheel housing 1 has a hollow cavity on the outside, and the sand discharge groove 2 is uniformly distributed in a ring shape around the median axis of the rear synchronous wheel housing 1. The rear synchronous wheel housing 1 is hollow on both sides, and the sand discharge groove 2 and the bevel 3 are added. When the synchronous wheel operates in transmission mode, sludge and sand can be quickly flushed out of the toothed grooves, increasing the service life of the synchronous belt and synchronous wheel.Steel balls 4 are arranged on both sides of the rear synchronous wheel housing 1, and a reverse-toothed cover 5 is placed in the center of the rear synchronous wheel housing 1, which is hinged to the rear synchronous wheel housing 1. The bevel 3 corresponds to the position of the sand discharge groove 2 in a uniform ring shape around the median axis of the reverse-toothed cover 5. The median axis of the reverse-toothed cover 5 coincides with the median axis of the rear synchronous wheel housing 1, and there is a hinged connection between the rear synchronous wheel housing 1 and the steel balls 4. The presence of steel balls 4 facilitates the rotation of the device during its use.

[0024] Both ends of the reverse-toothed cover 5 are provided with claw-shaped grooves 6, and a retaining spring 7 is fixed to one side of the reverse-toothed cover 5, with retaining claws 8 located between the retaining spring 7 and the claw-shaped grooves 6. The claw-shaped grooves 6 are symmetrical with respect to the median axis of the reverse-toothed cover 5, and there is a movable linkage between the claw-shaped grooves 6 and the retaining claws 8. The retaining claws The retaining clips 8 can be placed in the claw grooves 6, and the retaining spring 7 secures the retaining clips 8 to the reverse-toothed cover 5, while holding the retaining spring 7 in place. The end of the reverse-toothed cover 5 is equipped with a locking ring 9, and there is a threaded connection between the locking ring 9 and the reverse-toothed cover 5. The center axis of the locking ring 9 coincides with the center axis of the reverse-toothed cover 5. Through the combination of the locking ring 9 and the reverse-toothed cover 5, the device can be disassembled and reassembled, which facilitates parts replacement. The edge of the rear synchronous wheel housing 1 is equipped with a drive belt 10, and a front synchronous wheel 11 is located at one end of the drive belt 10.

[0025] Operating Principle: Before using this device, personnel first perform a check to ensure there are no problems, and then proceed with its use. Thanks to the combination of the locking ring 9 and the reverse-toothed cover 5, the device can be disassembled and reassembled, which facilitates the replacement of parts and also prevents the steel balls 4 from falling out of the rear synchronous wheel housing 1. The presence of the steel balls 4 facilitates the rotation of the device during use. The retaining claws 8 can be placed in the claw-shaped grooves 6, and the retaining spring 7 secures the retaining claws 8 to the reverse-toothed cover 5, while holding the retaining spring 7 in place. The rear synchronous wheel housing 1 and the front synchronous wheel 11 are hollow on the sides, which incorporates the sand discharge groove 2 and the bevel 3.When the synchronous wheel is in drive mode, mud and sand can be quickly expelled from the toothed grooves, increasing the service life of both the synchronous belt and the synchronous wheel. Furthermore, the rear synchronous wheel housing 1 is designed so that the toothed retaining edges are offset and alternate on each side. This ensures efficient and correct belt engagement with the pulley teeth during belt and pulley rotation, preventing belt slippage and incorrect drive, thus improving the practicality of the device. Through the use of the front synchronous wheel 11, the rear synchronous wheel housing 1, and the drive belt 10, the objective of synchronous transmission can be achieved.The external structure of the front synchronous wheel 11 is similar to that of the rear synchronous wheel housing 1, and the internal structure of the front synchronous wheel 11 is not limited to a five-claw design but can be adapted to three, four, six-claw, etc., internal structures, depending on the needs of different customers in the market. The tooth structure of the rear synchronous wheel housing 1 is not limited to the three listed structures (three claws, nine teeth, and flywheel) but can also be applied to many areas requiring a similar synchronous wheel structure. The distance between the... The teeth of the rear synchronous wheel housing 1 can be flexibly adjusted according to specific customer requirements in the market.

[0026] For professionals in the field, it is evident that this invention is not limited to the details of the embodiments given above. In fact, it can be implemented in other specific forms without departing from the scope of this invention. Therefore, these examples should be considered as demonstrations, and not as restrictions.
