The difference between bicycle cassette freewheel and bicyle thread freewheel

The difference between bicycle cassette freewheel and bicyle thread freewheel is the disassembly and construction and the difference in the use of vehicles.

Disassembly is different:

The flywheel and the flower drum are connected by spline base and lock plate, and the tooth plate can be disassembled. The teeth of the card fly a card together, there is a base in the middle, one can be set up, 9 speed is 9 flywheels, if there is a separate flywheel bad, can be replaced separately. The spinning flywheel of the mountain bike refers to the spinning flywheel. The flywheel and the flower drum are connected in a threaded manner, and the tooth blade cannot be disassembled. Spin is one, if one tooth is broken to replace all.

Different structures:

The ratchet structure of the rotary flywheel is inside the flywheel, not on the flower drum, and the single-speed flywheel of a traditional bicycle also belongs to this structure. The ratchet structure of the cassette flywheel is inside the base of the flower drum, and the flywheel is composed of only a number of teeth, and does not have any complex internal structure.

In appearance, the difference can be seen from the fixed position of the smallest flywheel. The box flywheel has a cover for securing it to the tower base. The screws are screwed directly into the base of the tower without a cover. The difference between flying trucks and rotating trucks is mainly in three aspects: different disassembly, different structure, and different vehicle uses. Once you know these properties, you can tell them apart.

Breaking it down is different. The mountain bike is a kind of flywheel, the flywheel and the flower drum are connected by spline seat and locking parts, and the teeth can be removed. The teeth of the flywheel are glued together one by one, and the base is in the middle, and you can put it on one by one. The 9-speed flywheel consists of nine flywheels, which can be replaced individually if any of them break. The spinning flywheel of a mountain bike refers to the spinning flywheel. The flywheel and the flower drum are connected by thread connection, and the teeth cannot be removed. Spinning and flying are one and the same.

If one tooth is broken, all the teeth should be replaced. The structure is different. The ratchet structure of the rotating flywheel is inside the flywheel, not on the flower drum. The single-speed flywheel of a traditional bicycle also belongs to this structure. The ratchet structure of the clamping flywheel is inside the base of the flower drum, and the flywheel is composed of only a few teeth without any complex internal structure.

Use different means of transportation. Spinning freewheels are more common in single-speed cars, climbing cars, older variable speed sports bikes, and low-end entry-level sports bikes, such as 6-speed and 7-speed cars. However, the middle and high-end products of modern sports bicycles, because of their more stable structure, lighter weight, and can make the smallest teeth smaller, so they use clip-on flywheels.
