Abstract
The utility model discloses the overriding clutch of a motorcycle. A plurality of grooves are evenly arranged on the rim of a cushion body, and roller clutch mechanisms are arranged in the grooves. The wedge-shaped convex block of each clutch mechanism is positioned on the bottom of each groove, a roller is installed between the convex block and the inner ring of a fluted disc frame to form a kinematic pair, one end of a thrust pin is connected with the roller, and the other end is provided with a spring, which is connected with the cushion body to slide back and forth. Because the clutch mechanisms are added and arranged between the cushion body of the rear wheel of the motorcycle and the fluted disc frame, when the motorcycle inertially runs and a throttle is retarded, an engine is in the state of idle speed, the rear wheel (the cushion body) can separate from a chain and the engine (the fluted disc frame) to freely rotate, as a result, the passive rotation of the engine is reduced, the ineffective friction of the engine is avoided, the service life of the engine is prolonged, and the fuel oil can be saved by over twenty percent.
Description
Technical field:
The utility model discloses a kind of overdrive clutch of motorcycle, belongs to motorcycle power transmission machinery technical field.
Background technique:
Existing motorcycle reaches when receiving throttle in the inertia traveling process, motor is in idling mode, and vehicle moves on, the trailing wheel quick rotation, thereby drive the passive high speed rotating of motor, therefore accelerated the unnecessary wearing and tearing of machine, chain bears bidirectional force simultaneously, influence its working life, the waste fuel oil.
Summary of the invention:
The utility model discloses a kind of overdrive clutch of motorcycle, has solved the problem of the passive rotation wearing and tearing of existing motorcycle engine machinery.
Technical solution of the present utility model is as follows: be evenly distributed with some grooves on the wheel rim of buffer body, device has the roller clutch mechanism in the groove.The wedge shaped projection device of clutch mechanism is in the bottom of groove, and roller is installed in projection and the fluted disc frame and constitutes kinematic pair between the ring, and thrust pin one end is connected with roller, and the other end is provided with spring and is connected with buffer body and can comes and goes slip.
When motor quickened to rotate, chain drove the fluted disc frame and rotates, and roller upwards rotates in the effect lower edge of spring and thrust pin wedge shaped projection, made buffer body (back wheels of vehicle) and fluted disc be configured to interlock, rotated with speed; When engine idle, fluted disc frame rotating speed (engine speed) is less than buffer body (back wheels of vehicle) rotating speed, and roller to turning down, is realized the disengaging of fluted disc frame and buffer body in the drive lower edge of buffer body wedge shaped projection, reaches the overdrive clutch purpose.
Good effect of the present utility model is as follows: set up clutch mechanism between the trailing wheel buffer body of motorcycle and fluted disc frame, motorcycle is in the inertia traveling process and when receiving throttle, motor is in idling mode, back wheels of vehicle (buffer body) can break away from connect freely and rotates with chain and motor (fluted disc frame), reduced the passive rotation of motor, avoided the invalid wearing and tearing of motor, prolonged the working life of motor, saved fuel oil simultaneously and reach more than 20%.
