Description

Bicycle wheel set with a strong device

The invention mainly discloses a bicycle wheel set, in particular a bicycle wheel set with a strong device between the hub and the spoke.

Along with global warming and climate change, people's awareness of environmental protection for energy conservation and carbon reduction has gradually risen, and the environmental protection movement has become the common responsibility of the global citizens. Bicycles are currently the lightest, less expensive, and less expensive maintenance and environmentally friendly means of transportation. Therefore, using bicycles as a means of transportation or commuting in the middle of commuting, or for leisure and fitness, has been widely accepted and popular. Therefore, in the case where the number of users is greatly increased, the safety of riding a bicycle is also paid more and more attention.

The bicycle kit generally includes a wheel set, a transmission system, and a brake system. The wheel set includes a hub, a spoke and a rim. The most common spoke wheel set on the market today was developed in 1860 by the United Kingdom using several wires to combine the drums and rims to replace heavy wooden wheels. In general, the wheel that drives the bicycle to travel is completely applied to the torque of the hub by stepping on the pedal, and the torque is transmitted by the spoke connected between the hub and the rim to drive the rim to rotate circumferentially to advance the bicycle. The combination of the hub, the rim and the spoke of the conventional wheel set is generally provided with a wheel hub on the hub, the wheel hub surface is provided with a plurality of guide holes, and the barbed end of the spoke head passes through the hub disk a guide hole, the threaded portion of the spoke is screwed to the inner edge of the rim through a spoke nut, In order to form a wheel that can drive a bicycle. For example, in the "Wheel hub for bicycle" patent of U.S. Patent No. 7,484,812, it is disclosed that a plurality of holes are provided at both ends of a hub for piercing the head portion of the spoke and engaging the same. Guide hole. Further, as disclosed in the "Cycle, tensioned spoked wheel assembly and hub therefor" patent of U.S. Patent No. 6,145,938, it is also disclosed that a hub has flanges at both ends, and the headed inner ends of the spokes are respectively stretched and stuck. At the flange, the other end of the spoke is screwed onto the rim by means of a spoke nut.

However, when the above-mentioned conventional wheel set is driven on the road surface, it is affected by the ground reaction force, and the reaction force is indirectly transmitted to the spokes, and the spokes are pushed against the center of the hub, so that the barb ends of the spokes cannot be hooked to the hub disk. The problem of falling off occurs in the guide hole, especially when the bicycle travels to the uneven road surface, and the vibration and reaction force generated cause the spoke off condition to be more serious.

In view of the above problems of the prior art, which cannot be effectively solved and overcome, the present applicant has filed this patent application to solve the aforementioned problems.

It is an object of the present invention to provide a bicycle wheel set having a rugged device.

Screw hole 48 and a through hole 49.

The two reinforcing devices 4 are respectively sleeved on the two tapered sections of the hub 1 Each of the reinforcing devices 4 includes the two sleeves 40. The annular groove 43 of the sleeve member 40 abuts against the tapered portion 14 of the hub 1. The extension portion 22 of the spoke assembly 2 is formed by the sleeve member 40. The opening 47 enters the slot 46 of the socket 40, so that the extension 22 of the spoke set 2 is restrained in the slot 46 of the sleeve 40, and one of the sides 203 of the extension 22 of the spoke set 2 abuts The first stop portion 44 of the sleeve member 40 provides a positioning function when the spoke set 2 is rotated relative to the hub 1 in the circumferential direction of the socket member 40. The top surface 201 and the bottom surface 202 of the extending portion 22 of the spoke group 2 respectively abut the first end portion 41 and the second blocking portion 45, and provide a positioning function of the spoke group 2 with respect to the hub 1 in the direction of the virtual axis A. The projection 24 of the spoke set 2 abuts against the second stop 45, providing a positioning function of the spoke set 2 relative to the hub 1 in the radial direction of the virtual axis A. Thereby, the spoke set 2 can be firmly coupled between the hub 1 and the rim 3 to prevent the spoke set 2 from being detached from the hub 1.

The screw holes 48 and the through holes 49 of one of the two sockets 40 respectively correspond to the through holes 49 and the screw holes 48 of the other socket member 40, so that the two connecting members 5 can pass through the two socket members respectively. The through hole 49 of the 40 is screwed into the screw hole 48 to connect the two sockets 40 to each other. The taper of the sleeve 40 is equal to the taper of the tapered section 14 of the hub 1, so that the two sleeves 40 are tightly sleeved on the tapered section 14 of the hub 1.

As described above, it can be concluded that the bicycle wheel set with the strong device of the present invention has the following advantages:

1. The bicycle wheel set of the invention having a rugged device, the side of the extension of the spoke set abutting against the first stop of the socket, providing the spoke set relative to Positioning function of the hub when rotating in the circumferential direction of the socket; opposite sides of the extension of the spoke group respectively abut the first end and the second stop, providing the spoke group along the virtual axis with respect to the hub Positioning function of the direction; the convex portion of the spoke group abuts against the second blocking portion, and provides a positioning function of the spoke group relative to the hub in the radial direction of the virtual axis A. Thereby, the spoke set can be firmly coupled between the hub and the rim.

2. The bicycle wheel set with the strong device of the present invention, the taper of the socket is equal to the tapered taper of the hub, so that the two sleeves are tightly sleeved on the tapered portion of the hub, thereby effectively avoiding The rugged device is released from the hub.

In summary, the bicycle wheel set with the strong device of the present invention is not seen in the prior art, so it has the novelty and progress of the patent, and the use value of the industry; the applicant is in accordance with the provisions of the patent law. The bureau issued an application for a patent for invention.
