Description

 Magnetic reset bicycle hub hub ratchet clutch structure  

The invention relates to a ratchet drive system, in particular to a hub portion of a bicycle, which utilizes a radial linear displacement clutch drive mode to achieve a one-way rotational drive work when pedaling.

The bicycle is driven by human power. It uses the pedaling action as the power source. It mainly combines the transmission principle of the toothed disc and the chain, and then drives the flower hub and the wheel to rotate in front of the vehicle body, so that the bicycle can advance in one direction. Riding. Since the pedaling of the bicycle only works in one-way rotation in the forward direction, although the motor is not driven when the pedal is not stepped on, the wheel and the vehicle body can continue to advance according to the inertia, so the ratchet device is provided by the flower hub structure. To achieve this idling.

In the bicycle flower hub structure, the utility model generally comprises a flower hub, and an axle, a bearing, a sleeve seat, a ratchet set and the like arranged in the flower hub, wherein the axle is connected with the front fork or the rear fork of the bicycle. Therefore, in a fixed state, the flower hub is combined with the rim by a plurality of spokes, and the sleeve seat provides the flywheel assembly position in the chain device; when the drive work advances, the pedal drive chain device can drive The sleeve seat rotates and simultaneously drives the ratchet wheel to rotate, and then indirectly drives the flower hub to rotate synchronously; when the air is not working, the chain device can be not driven without stepping on the crank, and the chain device and the sleeve seat are stopped and driven. Rotating, the ratchet set in the sleeve is in a non-engaging dislocation state, in which case the hub and the rim are continuously rotated due to inertial motion.

The ratcheting device of the bicycle rim can be roughly divided into two types: "radial drive" and "end drive". The "end drive", also known as "axial drive", is one of the ratchet sets. a ratchet is disposed on an end surface of the sleeve seat, and another second ratchet is disposed on an end surface of the ratchet ring, and the ratchet ring is fixed in the predetermined portion of the flower hub, thereby The first and second ratchets are in meshing drive, that is, the two ratchets are driven to mesh with each other in the axial direction of the axle. Such a structure is disclosed in the "Bicycle Wheel Hub Structure" disclosed in U.S. Patent No. 6,123,179, and the "Bicycle Flower Hub Structure" disclosed in Japanese Patent No. 101,144,857, and the "Drum of the Japanese Patent No. 105,213,231.

The term "radial drive" means that the ratchet assembly is provided with a first ratchet on the outer diameter edge of the sleeve, and the other second ratchet is disposed on the inner edge wall of the hub, whereby each of the 1. The second ratchet is driven in mesh with each other, that is, the pawl is rotated in the diameter direction of the axle to abut the driving ratchet. Such a bicycle ratchet form is the research direction of the present invention. The ratcheting meshing method can be further divided into a "pawl type" and a "puncture type", wherein the "pawl type" has a plurality of pawl rings disposed on the outer diameter edge of the sleeve seat, and can be made thereon. The rotation of the preset range, when each of the pawls rotates the exposed ratchet portion toward the outer diameter edge of the sleeve seat, can effectively mesh with the ratchet ring provided in the flower hub, thereby generating a one-way driving rotation Such a "pawl type" bicycle flower hub ratchet structure, such as the "non-elastic magnetic flower hub structure of a bicycle" disclosed in the new patent No. 105202480, and the "flower hub" disclosed in the domestic patent No. 104205892 Ratchet structure."
