Bicycle ratchet structure without elastic parts

The present invention relates to a ratcheting device for bicycles, in particular to a flower hub, which does not require any elastic members, and can rotate the pawl to engage with the ratchet teeth, thereby generating a one-way rotation work.

The bicycle is mainly used to step on the pedal crank, and the flywheel on the wheel after the chain is driven to drive the sleeve set and the flower hub which are connected with the flywheel, so that the rear wheel rotates to cause the vehicle body to travel forward. Moreover, in order to prevent the wheel from continuing to advance according to its inertia when the pedal is not stepped on, a ratchet set capable of one-way rotation is provided between the flower hub and the sleeve set.

The ratchet structure of the bicycle comprises a ratchet ring, a ratchet, a pawl and an elastic member, wherein the ratchet ring is fixed inside the flower hub, and the inner ring of the ratchet ring is provided with a plurality of The ratchet, the pawl has a plurality of rings that are pivotally connected to one side end surface of the sleeve seat, and maintains a rotation operation within a preset range, and then cooperates with an elastic member to provide an elastic force of each of the pawls, so that the ratchet The claw can be externally rotated to expose the state of its engaging end to facilitate the engagement with the ratchet to perform the transmission.

By using the external rotation of the pawl and the ratchet, the ratchet ring can be driven by the pawl by stepping on the chain drive flywheel, the sleeve seat and the pawl on the sleeve seat, and the ratchet ring is driven by the pawl. The phase-fixed flower hub is synchronously driven to form the entire rotary working state. When the pedal is not stepped on, the rotation of the pawl on the flywheel, the sleeve seat and the sleeve seat does not rotate. At this time, the ratchet ring and the flower hub are continuously rotated due to the inertia, and the ratchet of the ring shape is rotated according to the rotation. Each of the pawls of the elastic touch is continuously rotated toward the sleeve, and is externally rotated by the elastic force of the elastic member, so that the squeaking state of the squeaking sound is generated.

Since the switching of the ratchet teeth by the pawl rotation is performed to generate the transmission of the one-way rotation work, the automatic external rotation of the pawl and the meshing action are extremely important, and whether the engagement between the jaw and the ratchet is appropriate State, and also affect the performance of the transmission force, on the other hand, it is suppressed The speed of the external rotation of the rotation is also the display of the sensitivity of the ratchet drive. At present, the technical application of the external rotation of the ratchet to mesh with the ratchet can be roughly divided into "magnetic type" and "elastic type", wherein the "magnetic type" is mainly provided by the magnetic element on the pawl. The manner in which the pawl is externally rotated toward the sleeve by the magnetic attraction between the ratchet ring of the metal material and the pawl, thereby engaging the ratchet; such a technique is disclosed in the new patent No. 100217248 "Bicycle wheel hub ratchet device".

The "elastic member" is a variety of elastic members that provide an elastic force to cause the pawl to be rotated. For example, the "bike flower hub structure" disclosed in the new patent No. 099206104 is attached to the pawl. A spring is provided at a predetermined portion between the pawl groove and the pawl groove to provide a force for pushing the pawl. In addition, the "one-way ratchet structure of a bicycle wheel hub" disclosed in the Japanese Patent No. 100219245, which uses a spring piece having a predetermined shape length, is disposed at a predetermined portion between the pawl and the pawl groove to provide a pawl direction. The force of external rotation. There is also a "ratchet structure for a bicycle hub" as disclosed in the Japanese Patent No. 102209016, which uses an R-shaped elastic piece disposed at a predetermined portion between the pawl and the pawl groove. The bicycle bicycle hub ratchet disclosed in the new patent No. 102211589, which is different from the above, is a spring ring-shaped elastic ring and a plurality of radial outer edge preset portions of the pawl. a structure in which each of the pawls generates a predetermined external rotation state due to contact with the elastic ring, thereby engaging the ratchet teeth.

In view of the above-mentioned conventional structure using the "elastic member", it mainly utilizes various shapes of elastic pieces or springs or coils to provide elastic force for pawl rotation, or a common hoop to provide a plurality of spines. The elastic force of the claws is used for its technical application; however, the technique of providing elastic force by the "elastic member" tends to be elastic and fatigued after the elastic member is used for a period of time, so that the pawl cannot smoothly rotate and not with the spine. When the teeth are meshed, the tooth removal occurs, which in turn affects the transmission efficiency of the force. When pedaling, there is a feeling of subsequent weakness. When the teeth are severely dislocated, the ratchet ring and the flower hub are not idling. On the other hand, the elastic members are mostly thin. It is easy to break or bend and deform, and it will delay or even cause the pawl to rotate, and it is quite troublesome to disassemble the entire set of flower hubs for repair and replacement of elastic parts; in addition, even if it is not stepped on Without passing the state of the action, the pawl continues to be in an externally rotated state due to the elastic force, and continues to collide and wear with each of the ratchets. Therefore, the service life of the pawl is relatively short, so that the maintenance cost is increased. Moreover, the friction and collision also affect the rotational inertia of the hub when the pedal is not stepped. When the friction is large, the rotation efficiency is lost quickly, and the wheel is not made. The time for self-rolling of the idling is shortened, the friction is small, the rotation efficiency is slower, and the wheel can roll for a longer period of time due to the idling of the wheel. The ratchet structure used by the elastic member tends to have a large frictional force. The seat spin inertia is poor.

Nowadays, the development of bicycle technology is quite mature. The demand for the transmission efficiency of bicycles is to be improved. Especially the riding bicycle is a movement between the human body and the body of the vehicle. Even if the transmission efficiency is slightly improved, a little labor-saving effect can be achieved. The passenger has a clear feeling. Therefore, the inventor of the present invention provides a bicycle wheel hub ratchet structure that does not require the use of an "elastic member" to solve the conventional ratchet structure of the "elastic member". The problem.

In view of the above, the present invention discloses a bicycle ratchet structure without elastic members, which comprises: a flower hub, which is disposed outside a shaft; a sleeve set is disposed on one side of the flower hub, and has a sleeve seat; a ratchet set is disposed between each of the flower hub and the sleeve set, and has a ratchet ring disposed at a predetermined position in the flower hub, and has a plurality of ratchets in a ring shape At least one pawl groove is disposed on the sleeve seat, and a pawl is pivotally disposed in the pawl groove, and is rotated in the pawl groove by a predetermined angle, and the pawl rotates radially to expose the The pawl groove can effectively mesh with the ratchet and drive; a delay damping device is disposed on one side of each of the pawl and the sleeve seat, and has a preset between the shaft and the flower hub a retardation seat, a transmission guide group, for providing a rotation guide for the rotation of the pawl and driving the delay seat to generate rotation, the transmission guide group having a preset long hole disposed above the delay seat At least one guiding slot, and a driving pin disposed at a predetermined portion of the pawl, the driving pin is disposed on the guiding And the limit movement in the middle; and the delaying seat having the preset damping is used to generate a delay time within the preset time difference, and the driving guide group guides the pulling pawl to generate the outer portion Rotating state, so no need to use any elastic parts, and when the pedal is not stepping on the work, the pawl will not automatically rotate externally, so the friction can be reduced, the spin inertia of the hub can be increased when the pedal is not stepped, and the idling can be reduced.
