Description
Technical field
The present invention relates to a kind of bicycle freewheel mechanism, belong to bicycle accessories field.
Background technology
Traditional bicycle ratchet mechanism is when idle running, and ratchet and pawl generation forward contacts, and the ratchet mechanism of this structure, when idle running, can produce certain frictional force, and during idle running, QIANJIN PIAN impact ratchet can produce bigger noise simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is: when overcoming ratchet idle running in prior art, the technical problem that ratchet and pawl still comes in contact, it is provided that a kind of novel ratchet mechanism.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of bicycle freewheel mechanism, connects including ratchet mechanism, axle skin and drive shaft, described axle skin and drive shaft turns；Described ratchet mechanism includes ratchet, rotation case and occlusion mechanism, and described ratchet is fixing on the driving shaft, and described rotation case is fixed on axle skin；
Described ratchet includes N number of ratchet, and occlusion mechanism includes N number of ratchet being arranged on rotation case；
Described ratchet includes pedestal, QIANJIN PIAN and clutch component, described pedestal is fixed in rotation case, pedestal is provided with the guide rail moved for QIANJIN PIAN, connected by diastole spring A elasticity between bottom and the end of guide rail of described QIANJIN PIAN, be provided with the inclined-plane matched with described ratchet at the top of QIANJIN PIAN；
The bar hole coaxial with diastole spring A driving direction it is provided with in described QIANJIN PIAN, clutch component is installed in bar hole, described clutch component includes pouring weight and diastole spring B, described pouring weight is along bar hole slidably, at pouring weight, the side of diastole spring A being provided with diastole spring B, the start axis of described diastole spring B is coaxial with bar hole.
As the further innovation of the present invention, the surface configuration in QIANJIN PIAN have one with the oil filler point connected inside bar hole.
As the further innovation of the present invention, it is a steel ball at described pouring weight.
As the further innovation of the present invention, the angle of the angle between axis and the tangent line of pedestal position of described pedestal is equal to the gradient of ratchet surface.
As the further innovation of the present invention, described QIANJIN PIAN is copper.
The invention has the beneficial effects as follows:
The present invention is by changing traditional rotary type QIANJIN PIAN mechanism, QIANJIN PIAN is changed into rectilinear movement, the clutch that one gravity is centrifugal is installed in QIANJIN PIAN simultaneously, when wheel rim generation fast idle, pouring weight can promote QIANJIN PIAN to be moved, so that QIANJIN PIAN is regained, no longer come in contact with ratchet, reduces frictional force during ratchet idle running, stop to make a noise when idle running, improve the comfort level ridden.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is described the most in a schematic way, and therefore it only shows the composition relevant with the present invention.
As it is shown in figure 1, the present invention is a kind of bicycle freewheel mechanism, including ratchet 8 mechanism, axle skin and drive shaft 9, described axle skin and drive shaft 9 are rotationally connected；Described ratchet 8 mechanism includes that ratchet 8, rotation case 1 and occlusion mechanism, described ratchet 8 are fixed in drive shaft 9, and described rotation case 1 is fixed on axle skin；
Described ratchet 8 includes N number of ratchet 7, and occlusion mechanism includes N number of ratchet being arranged on rotation case 1；
Described ratchet includes pedestal 2, QIANJIN PIAN 4 and clutch component, described pedestal 2 is fixed in rotation case 1, it is provided with the guide rail moved for QIANJIN PIAN 4 on the base 2, connected by diastole spring A elasticity between bottom and the end of guide rail of described QIANJIN PIAN 4, be provided with the inclined-plane matched with described ratchet 7 at the top of QIANJIN PIAN 4；
The bar hole coaxial with diastole spring A3 driving direction it is provided with in described QIANJIN PIAN 4, clutch component is installed in bar hole, described clutch component includes pouring weight 6 and diastole spring B 5, described pouring weight 6 is along bar hole slidably, at pouring weight 6, the side of diastole spring A3 being provided with diastole spring B 5, the start axis of described diastole spring B 5 is coaxial with bar hole；
Surface configuration in QIANJIN PIAN 4 have one with the oil filler point connected inside bar hole；It is a steel ball at described pouring weight 6；
The angle of the angle between axis and the tangent line of pedestal 2 position of described pedestal 2 is equal to the gradient on ratchet 7 surface；Described QIANJIN PIAN 4 is copper.
When ratchet mechanism dallies, pouring weight 6 compresses diastole spring B 5, so that QIANJIN PIAN 4 promotes diastole spring A3 to realize reclaiming, now ratchet does not comes in contact with ratchet, reduces frictional force, during rotating forward, at ratchet, rotating speed reduces, and QIANJIN PIAN 4 is stretched out and is engaged with ratchet, drives wheel turns.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, relevant staff can carry out various change and amendment completely in the range of without departing from this invention technological thought.The content that the technical scope of this invention is not limited in description, it is necessary to determine its technical scope according to right.
