Description

Bicycle wheel with beveled drive

The present invention relates to the technical field of bicycles, and in particular to a bicycle wheel hub with a beveled drive.

In general, the drive mechanism of a bicycle is formed by engaging a ratchet ring in a hub with a plurality of pawls at the end of a ratchet cylinder. However, for BMX-dedicated bicycles, users often need to control the bicycle to perform a variety of static or dynamic changes, so the reaction time of the hub is short, so that the action can be completed in real time.

Taiwan Patent No. M356633 discloses a hub. The technique of the prior art mentions that a polygonal bump pushes a roller on a clutch ring to protrude outward, and the roller contacts a combination of a transmission ring and a hub body to drive the hub body to rotate. Effect. U.S. Patent No. 6,130,299,293 discloses a hub structure. The technical content of the prior patent mentions that a clutch mechanism, a pawl and a spring constitute a clutch mechanism. When the pawl of the clutch mechanism protrudes to engage an internal ring gear, the hub can be driven to rotate. The drive mechanism disclosed above still uses a pawl structure, so the reaction rate of the hub cannot be improved.

The purpose of the present invention is to provide a bicycle hub having a beveled drive that has the effect of improving the sensitivity of the hub to drive rotation.

In order to achieve the above objects and effects, the hub structure disclosed in the present invention comprises an axially mounted a driven component, a transmission component and a spindle, which are a hub body, wherein the axial interior of the hub body has a The outer surface of the mandrel has a retaining edge; the driven component includes an engaging ring, a follower, a resisting disc and a spring, wherein the engaging ring has a through hole in the axial direction, and the The perforated annular inner wall surface is an inclined surface; the outer surface of one end of the driven member forms an inclined abutting surface, and the driven member has a transmission member through hole in the axial direction, and the inner wall surface of the transmission member has a thread The driving member is connected to a driving head at one end of the engaging tube, the outer surface of the engaging tube has an engaging thread; the driven component, the transmitting member and the spindle are mounted in an axial inner portion of the hub body, wherein the driving member One end of the spring abuts against the retaining edge, the other end of the spring abuts against the abutting disc, one end of the follower abuts against the abutting disc, and the other end of the follower protrudes into the engaging ring Inside the perforation, and the oblique abutment corresponds to An engaging surface is locked in the accommodating space of the hub body, the engaging tube of the transmission member passes through the engaging ring, and the engaging thread of the outer surface of the engaging tube of the transmission member engages the driven The thread is axially threaded by the transmission member.

The purpose and function of the present invention are as follows, and the preferred embodiments are described in detail, and the components of the present invention and the combinations thereof are described in detail.

Referring to Figures 1 and 2, the bicycle hub disclosed in the present embodiment includes a combination of a hub body 10, a driven assembly 20 and a transmission member 30. More specifically, the driven assembly 20 is mounted in an accommodating space 12 axially inside the hub body 10. One end of the transmission member 30 extends into the axial inner portion of the driven assembly 30, and the transmission member 30 and the driven assembly 20 are coupled to each other. Further, the other end of the transmission member 30 is located at one end of the hub body 10. The outside. A mandrel 40 is used to pass through the axial direction of the hub body 10, and the mandrel 40 also passes through the driven component 20 and the axial interior of the transmission member 30.

More specifically, the outer peripheral face of the mandrel 40 has a rim 42. The retaining edge 42 may be formed directly on the outer surface of the mandrel 40 or may be attached to the outer surface of the mandrel 40 by an annular member.

The driven assembly 20 includes a combination of an engagement ring 21, a follower 22, a resisting disk 23 and a spring 24. Specifically, the engaging ring 21 has a through hole 210 in the axial direction, and a part or all of the annular inner wall surface of the through hole 210 is an inclined surface 212. An outer surface of one end of the follower 22 is formed with an inclined abutting surface 220; further, the surface of the inclined abutting surface 220 has a plurality of ribs 222. Secondly, the follower 22 has a transmission member bore 224 in the axial direction, and the inner wall surface of the transmission member bore 224 has a thread 226. The abutting plate 23 has a through hole 230 in the axial direction. The spring 24 is a tension spring.

The transmission member 30 is connected to a driving head 34 at one end of a meshing tube 32. The outer surface of the engagement tube 32 has an engagement thread 320.

The driven component 20, the transmission member 30 and the mandrel are mounted on an axially inner portion of the hub body 10, wherein one end of the spring 24 abuts against the rib 42 and the other end of the spring 24 abuts against the yoke Disk 23. One end of the follower 22 abuts against the abutting plate 23, and the other end of the follower 22 projects into the through hole 210 of the engaging ring 21, and the reclining abutting surface 220 corresponds to the inclined surface 212. The engagement ring 21 is locked in the accommodating space 12 of the hub body 10 . The engaging tube 32 of the transmission member 30 passes through the engaging ring 21, and the engaging thread 320 of the outer surface of the engaging tube 32 of the transmission member 30 engages the thread of the transmission member through hole 224 of the follower 22 in the axial direction. 226.

Referring to FIG. 3, the transmission member 30 is rotated (toward the forward direction of the bicycle), and the engagement tube 32 can pull the follower 22 toward the engagement ring 21 by the engagement threads 320 and the thread 226. Thus, the inclined abutting surface 220 at one end of the follower 22 can abut the inclined surface 212 of the engaging ring 21, and the torque provided by the transmitting member 30 can be transmitted to the engaging ring 21 by the mode of contact transmission. And the hub body 10.

The transmission member 30 is rotated in the reverse direction (the opposite direction of the bicycle advancement), and the spring 24 provides a sufficient amount of spring force to push against the abutment disk 23, so that the follower member 22 does not cause a disengagement from the transmission member 30. In addition, the degree of abutment of the reclining surface 220 and the inclined surface 212 is reduced, so that the hub body 10 can still rotate smoothly.

It can be understood that the transmission member 30 is further rotated in the forward direction of the bicycle, and the driven member 22 can be driven to be slightly displaced so that the inclined abutting surface 220 of one end immediately abuts against the inclined surface 212 of the engaging ring 21, Further, the meshing ring 21 and the hub body 10 are driven to rotate again. In addition, the ribs 222 inclined to the surface of the abutting surface 220 can effectively increase the contact force and the opposing force of the inclined abutting surface 220 and the inclined surface 212.

According to the above, the hub structure disclosed in the embodiment has the inclined surface abutting mechanism between the transmission member and the driven member, so that the structure is simplified and the sensitivity of the hub body to be driven is improved.
