Embodiment Construction

[0035] First please refer to Figure 1-3 As shown, the ratchet wheel of a bicycle hub provided by the present invention is located between the hub seat 10 and a sleeve seat 20, and includes: a stop ring 30 and a driving group located in the hub seat 10 40 , a driven group 50 disposed in the stop ring 30 , and a magnetic group 60 between each driven group 50 and the hub seat 10 .

[0036] The hub seat 10 is a hollow seat body, one end surface of which is recessed with a set of joint grooves 11 with a preset depth;

[0037] The sleeve seat 20 is hollow and cylindrical, and one end thereof is provided with a connecting portion 21 with a smaller outer diameter.

[0038] The stop ring 30 is a hollow ring that is screwed in the assembly groove 11, and its two side edges are respectively set as a set of end faces 31 and a free end face 32; the stop ring 30 is provided with a preset taper An oblique cone inner hole 33 is a penetrating inner diameter hole tapered from the set end sur...

Abstract

The invention mainly provides a ratchet wheel of a wheel hub of a bicycle. The ratchet wheel is arranged between a first wheel hub base and a sleeve base and comprises a blocking ring which is arranged inside the wheel bub base fixedly, a driven base, a conical surface, a blocking portion and a magnetic group; wherein an inclined cone inner hole and a blocking edge are arranged on the blocking ring, a driving base is arranged between the wheel hub base and the sleeve base, and a plurality of first ratchet teeth are arranged on a one side end face of the driving base, which faces towards an axial ring inside the wheel hub base; the driven base is arranged inside the inclined cone inner hole and corresponds to a driving group, the external diameter of the conical surface can be matched with the inclined cone inner hole, the blocking portion can be blocked by the blocking edge in one direction, a driven base ring is provided with a plurality of second ratchet teeth which can be meshed with the first ratchet teeth, and the magnetic group is arranged between the driven base and the wheel hub base and provided with a first magnetic part and a second magnetic part, which are respectively arranged inside the wheel hub base and on the driven base and are in a mutual exclusion state. Thus, the inclined cone inner hole which is in an inclined cone shape and the conical surface design are adopted, the friction force is reduced, the restoring speed of the driven base is increased, and the sensitivity of a ratchet wheel group is improved further.

Description

technical field [0001] The invention relates to a ratchet wheel, especially a ratchet wheel used in the wheel hub of a bicycle. The ratchet wheel is used in the wheel hub of a bicycle. The ratchet wheel of the bicycle wheel hub is conveniently assembled and firmly combined by coordinating with a magnetic member to generate automatic return. Background technique [0002] The hub structure of a bicycle is mainly composed of a hub seat, a shaft, a rotating group, and a toothed plate in order to provide the positioning of the wheel shaft and the smooth rotation of the rim; Cylinder seat and speed change device; if distinguished according to the transmission mode, the structure can be divided into "one-way" and "two-way", where "one-way" means that the hub rotation can only rotate in one direction and can be transmitted. This direction is usually It is the forward direction of the bicycle, and the idling state of no transmission in the reverse direction; "two-way" refers to the h...
