Abstract
The utility model relates to an overdrive clutch for a motorcycle. In the utility model, a driving chain pulley (1) which is arranged on the output shaft of a gearbox is formed in a shaft fit way. The outer end of the driving chain pulley is formed into a concave end face. The inner part of the concave end face is provided with a star rotator (2) with a spline groove. The inclined plane of the star rotator is provided with a compression spring and a knock pin. The top end of the knock pin is provided with a cylindrical roller (3), which is spaced by the star rotator and the driving chain pulley. The structure solves the problem that the impact force can be generated by the original structure when shifting, and the running performance of the motorcycle is improved.
Description
The utility model belongs to clutch for motorcycle.
The motorcycle of at present domestic and international various band shelves is all regulated the rotating speed of output shaft of gear-box by clutch when gear shift, drive drive sprocket, by movable sprocket, reaches walking speed change purpose through chain drive.But,, influenced the rideability of motorcycle so the gap that wearing and tearing form between the mode of its cooperation and spline thereof causes motorcycle to produce certain impact porpoising when gear shift owing to be the spline fitted transmission between output shaft of gear-box and drive sprocket.
The purpose of this utility model provides a kind of impact porpoising can eliminate motorcycle shift the time, improves the clutch of the rideability of motorcycle.
The utility model is to solve above-mentioned topic together like this: the drive sprocket on the output shaft of motorcycle gear box is changed a social system, becoming spline fitted cooperates into axle, the spill end face is processed in the outer end of drive sprocket, loading onto the star of the wounded in the battle keyway of a cover in the spill end face turns, on turning the inclined-plane, star loads onto pressure spring and ejector pin, cylindrical roller is loaded onto on top at ejector pin, and it is spacing with drive sprocket to be turned by star, promptly form ratchet mechanism, spacing with the washer sealing more at last, just formed cover novel clutch, i.e. a free wheel device.This free wheel device is contained on the motorcycle gear box output shaft, has just finished the purpose of this utility model.
The overdrive clutch of motorcycle that adopts said method to make, just can utilize drive sprocket and output shaft and star relatively rotating between turning, buffering drive sprocket and by the transmission of power between movable sprocket, the unexpected variation of speed when eliminating motorcycle shift, make motorcycle when gear shift, almost not have the impact porpoising, thereby improved the rideability of motorcycle, made the motorcycle that this free wheel device is housed have characteristics such as driving stability, fuel-economizing.
Introduce a kind of embodiment below in conjunction with accompanying drawing.
Accompanying drawing 1 is an erection drawing of the present utility model, and accompanying drawing 2 is sectional drawings that the A-A hatching line is cut open.As shown in the figure, 1 is through the drive sprocket of the transformation of the way among the figure, has keyway on the former endoporus, the existing keyway of having cancelled, with output shaft (8) for movingly.In the end of drive sprocket, be processed into concave surface; 2 is that the star that is contained in the concave surface is turned among the figure, and spring 7, cylindrical roller 3, ejector pin 6 are contained on the outer rim inclined-plane that star turns, and washer 4 is in order to spacing, is fixed on star with screw 5 and turns on 2, and star is turned and output shaft of gear-box is a splined.
When motorcycle quickened, output shaft quickened by clockwise direction shown in Figure 2, and drive sprocket 1 and motorcycle gear box output shaft are in state movingly when initial, do not quicken synchronously with output shaft, thus the impact force that buffering is quickened.Along with the raising of the speed of a motor vehicle, under action of centrifugal force, cylindrical roller 3 is turned sliding on 2 the inclined-plane along star, and the relative movement with between locked drive sprocket 1 of the form of the angle of wedge and the motorcycle gear box output shaft is passed to by movable sprocket power, drives motorcycle and advances.When motorcycle slows down, along with reducing of centrifugal force, spring 7 shrinks, ejector pin 6 withdrawals, and cylindrical roller 3 glides along star 2 inclined-planes of turning, drive sprocket 1 and motorcycle gear box output shaft are state movingly once again, drive sprocket does not slow down synchronously with pto, thereby regulates the impact force when slowing down, when drive sprocket 1 is consistent with motorcycle gear box output shaft revolution, then locked once again, make the motorcycle cruising.
Claims (1)
1, a kind of motorcycle free wheel device, it is characterized in that: its output shaft of gear-box is that axle cooperates with the no spline fitted of drive sprocket (1), the outer end of drive sprocket is the spill end face, the poor star of the wounded in the battle key of one cover turn (2) is housed on the matrix end face, on turning the inclined-plane, star loads onto pressure spring and ejector pin, cylindrical roller (3) is housed on the top of ejector pin, and it is spacing with drive sprocket to be turned by star.
