Ratchet ring structure connected to a hub assembly

Abstract

The invention relates to a ratchet ring structure connected to a hub assembly. The ratchet ring structure is suitable for a hub assembly. The hub assembly is provided with a virtual rotation shaft. Along the virtual rotation shaft, a connection space is arranged in a recessed mode. The annular wall of the connection space is provided with a clamping tooth part. The ratchet ring structure that cooperates with the hub assembly comprises a ratchet ring body that can be connected to the connection space rotatingly along the virtual rotation shaft; a first tooth part, which is clamped with the clamping tooth part; and a second tooth part, which is opposite to the first tooth part. The provided ratchet ring structure can avoid the situation that the radical force applied on the hub assembly is too large when a torque is applied, and the cost is reduced.

Description

technical field [0001] The present invention relates to a ratchet ring structure, in particular to a ratchet ring structure combined with a hub assembly. Background technique [0002] There are quite a wide range of groups of people who ride bicycles. No matter children, old people or young people, almost all have a bicycle. Many students, especially, use bicycles as a means of transportation when going to and from school; coupled with the popularity of sports and leisure and the awareness of environmental protection Head-up bicycles are gradually replacing household cars and motorcycles, and as more and more users use bicycles, users' requirements for bicycles are not limited to the function of transportation, and the improvement of various components of bicycles has also made the bicycle industry The development is more proficient. [0003] The hub of a bicycle is the axis at the center of the wheel. When the bicycle is moving, it is pressed by the weight of the rider and...

Problems solved by technology

Therefore, in order to prevent the ratchet ring 2 from being peeled off under high torque, the hub seat 1 must be thick, and the threads must be very rough, but the threads of the ratchet ring 2 and the hub seat 1 will be actuated. Collide with each other, easy to produce wear and noise, and the hub seat 1 is usually made of aluminum, so some threads of the ratchet ring 2 and the threads inside the hub seat will become thinner and thinner, so that the threads of the ratchet ring 2 Unable to rotate externally smoothly and fail to mesh with the inside of the hub seat 1, resulting in tooth detachment, which in turn affects the power transfer efficiency

However, if the thickness of the hub base 1 is reduced to reduce the weight, the rigidity of the hub base 1 will be insufficient, and it will not be able to withstand external forces such as radial force, which will cause damage to the hub base 1 and affect the safety and smoothness of cycling. On the other hand, the pressure generated by the thread causes the hub seat 1 to expand and expand during operation, which is prone to breakage or bending deformation. Each set of hubs needs to be dismantled, which is not only time-consuming and labor-intensive, but also wastes a lot of manufacturing costs
