Abstract
A one-way clutch belongs to the one-way clutch transmission field like bicycles. The one-way clutch comprises a removable key, a spring, an outer wheel and a driving shaft. The removable key is assembled with the driving shaft through the spring, and the removable key and the driving shaft both are arranged inside the outer wheel. The one-way clutch overcomes shortcomings that edges of an existing ratchet wheel are prone to abrasion and the existing ratchet wheel is small in impact resistance, and therefore the one-way clutch is reliable in motion, and is prone to achieving mass-production.
Description
Technical field
The utility model relates to the one-way clutch transmission field of bicycle etc., specifically is a kind of new-type overrunning clutch.
Background technique
Bicycle generally uses ratchet mechanism at present, and ratchet mechanism is made up of ratchet, ratchet and frame.Because when realizing unidirectional transmission, ratchet will repeatedly streak from the hook tooth back, and the back of tooth of pawl-and-gearing all compare sharply, so pawl-and-gearing is all easy to wear, and the situation of transmission failure often occurs.
The model utility content
It is easy to wear that the purpose of the utility model is to solve traditional ratchet mechanism, the time problem such as inefficacy is arranged, make up high, the overrunning clutch more reliably of a kind of intensity.Realize through following technological scheme:
The described overrunning clutch of the utility model comprises removable key, spring, outer ring wheel and driving shaft, it is characterized in that removable key is contained in the inside of outer ring wheel jointly through spring and driving shaft assembling.
The utility model traditional overrunning clutch of comparing has the following advantages:
1, wear-resisting, good impact resistance, it is easy to wear to have broken away from traditional ratchet, the shortcoming that impact resistance is little.
2, reliable motion, good economy performance is prone to realize producing in enormous quantities.
Description of drawings
Fig. 1 is the said single clutch structural representation of the utility model.
Embodiment
Below in conjunction with the overrunning clutch structural representation the utility model is further specified:
As shown in the figure, this overrunning clutch is made up of 4 parts: removable key 1, spring 2, outer ring wheel 3 and driving shaft 4.Driving shaft 4 skies are enclosed within on the driven shaft that is connected with outer ring wheel 3.Removable key 1 links to each other with driving shaft 4 usefulness springs 2.When driving shaft 4 clockwise directions rotated, removable key 1 just inserted the sulculus of outer ring wheel 3, made the outer ring wheel and then turn over a certain angle.Do when counterclockwise rotating when driving shaft 4, the back of tooth of removable key 1 wheel 3 from the outer ring slips over, outer ring wheel transfixion.After slipping over a groove, removable key 1 moves in circles and realizes the one-way clutch function again by spring 2 jack-up.
Claims (1)
1. an overrunning clutch comprises removable key, spring, outer ring wheel and driving shaft, it is characterized in that removable key is contained in the inside of outer ring wheel jointly through spring and driving shaft assembling.
