Abstract
The utility model relates to the technical field of bicycle parts, in particular to a pawl structure of a bicycle hub. The pawl structure comprises a ratchet wheel arranged outside a hub core shaft in a sleeved mode, the ratchet wheel is sleeved with a pawl ring in a cooperation mode, the pawl ring comprises an outer ring, a plurality of ratchet sets are arranged on the inner wall of the outer ring, the ratchet sets comprise pawl bodies, a spring is arranged on one side of each pawl body, and the springs and the outer ring are fixed in a welding mode. Due to the fact that the springs are arranged on one sides of the pawl bodies, certain elasticity is achieved when the pawl bodies rotate. In addition, an elastic wear plate is arranged between the ratchet wheel and a hook-shaped claw, when the pawl bodies are meshed with the ratchet wheel, the ratchet wheel can be in flexible contact with the pawl bodies, sounds are prevented from being generated in the driving process, and the service life of the ratchet wheel and the service life of the pawl bodies are prolonged.
Description
Technical field
The utility model relates to the bicycle part technical field, particularly a kind of pawl structures of bicycle drive shaft.
Background technology
Flower-drum is the indispensable parts of bicycle.Flower-drum of the prior art, in motion, the sound can occur, reason is to have produced room between the ratchet of flower-drum and pawl position, can not be directly stressed when the application of force, could produce power after must making ratchet and the ratchet position contacting, therefore in motion, because idle running produces the sound and can produce wearing and tearing, can have influence on the normal engagement of ratchet and ratchet position when serious.
The utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of and produces the sound while avoiding travelling, and can guarantee the normal engagement of ratchet and ratchet, extends the pawl structures of the bicycle drive shaft in its service life.
For achieving the above object, the utility model is by the following technical solutions: a kind of pawl structures of bicycle drive shaft, comprise and be sheathed on the outer ratchet of flower-drum mandrel, the ratchet fit on is socketed with the ratchet ring, described ratchet ring comprises outer ring, and the outer ring inwall is provided with some ratchet groups, and the ratchet group comprises pawl body, pawl body one side is provided with spring, and spring and outer ring are welded and fixed.
Wherein, described pawl body comprises the active segment be connected with spring, and active segment is connected with the linkage section be connected with ratchet, and the linkage section front end is connected with the hook pawl.
Wherein, be provided with the elastic wear-resisting sheet between described ratchet and hook pawl.
The utility model beneficial effect is: the utility model comprises the ratchet be sheathed on outside the flower-drum mandrel, the ratchet fit on is socketed with the ratchet ring, described ratchet ring comprises outer ring, the outer ring inwall is provided with some ratchet groups, the ratchet group comprises pawl body, pawl body one side is provided with spring, and spring and outer ring are welded and fixed; The utility model is by arranging spring in pawl body one side, make like this, pawl body has certain elasticity when revolution, in addition, be provided with the elastic wear-resisting sheet between ratchet and hook pawl, when pawl body and ratchet engagement, can make ratchet and pawl body flexible contact like this, produce the sound while avoiding travelling, extend the service life of ratchet and pawl body.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below with embodiment, the utility model is described in further detail, is not practical range of the present utility model is limited to this.
As shown in Figure 1, a kind of pawl structures of bicycle drive shaft, comprise and be sheathed on the outer ratchet of flower-drum mandrel, the ratchet fit on is socketed with the ratchet ring, described ratchet ring comprises outer ring 1, and outer ring 1 inwall is provided with some ratchet groups, and the ratchet group comprises pawl body 2, pawl body 2 one sides are provided with spring 3, and spring 3 is welded and fixed with outer ring 1; Described pawl body 2 comprises the active segment be connected with spring 3, active segment is connected with the linkage section be connected with ratchet, the linkage section front end is connected with hook pawl 4, the utility model is by arranging spring 3 in pawl body one side, make like this, pawl body 2 has certain elasticity when revolution, in addition, be provided with the elastic wear-resisting sheet between ratchet and hook pawl 4, like this when pawl body 2 meshes with ratchet, can make ratchet and pawl body 2 flexible contacts, produce the sound while avoiding travelling, extend the service life of ratchet and pawl body 2.
The above is only better embodiment of the present utility model, and the equivalence of doing according to the described structure of the utility model patent claim, feature and principle therefore all changes or modifies, and is included in the utility model patent claim.
