Abstract
The invention discloses an overrunning clutch device of a motorcycle. Notches (2a) in circumferential uniform distribution are formed in the circular wall of a housing (2), a drive plate (3) is arranged in the housing (2), outer teeth on the drive plate (3) are in one-to-one correspondence to the notches (2a) in the housing (2) and embedded in the corresponding notches (2a) in the housing (2), the drive plate (3) is fixed to the outer ring of an overrunning clutch (4) which sleeves a roller path column (5), and a roller (4a) in the overrunning clutch (4) is in rolling fit with the roller path column (5). An existing clutch housing combination and the overrunning clutch are combined ingeniously, a clutch function can be realized automatically, gear shifting is simpler and lighter, and the overrunning clutch device has the advantages of ingenious design, easiness in implementation and modification, low modification cost, fuel saving, good reliability and the like and is applicable to various motorcycle engines.
Description
Technical field
The present invention relates to a kind of motorcycle engine component, the overrunning type clutch device particularly on motorcycle.
Background technique
Clutch is the vitals in motorcycle engine, to ensure between the bent axle and transmission main shaft of motor or to block engine power and export according to the needs transmission of motorcycle driving.Existing clutch is generally combined by outer cover and central sleeve combination two large divisions is formed, not only complex structure, assembling difficulty, cost of production is higher, and shift gears time need manual control outer cover combine and central sleeve combine between friction pair throw off, the convenience of operation is poor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of motorcycle overrunning type clutch device that can conveniently shift gears.
Technological scheme of the present invention is as follows: a kind of motorcycle overrunning type clutch device, comprise the driven gear (1) and outer cover (2) that are fixed together, its key is: on the ring wall of described outer cover (2), have circumferentially equally distributed breach (2a), and drive plate (3) is provided with in outer cover (2), the excircle of this drive plate (3) is formed with circumferentially equally distributed external tooth, breach (2a) one_to_one corresponding on external tooth on drive plate (3) and outer cover (2), and the external tooth on drive plate (3) embeds in the corresponding breach (2a) on outer cover (2), described drive plate (3) fixes with the outer ring of free wheel device (4), this free wheel device (4) is set on raceway post (5), roller (4a) in free wheel device (4) rolls with described raceway post (5) and coordinates, have at the center of described raceway post (5) can with the splined hole of transmission main shaft spline fitted.
Adopt above technological scheme, the moment of torsion of crankshaft of motorcycle transmission is transferred to driven gear through driving gear, driven gear is rotated together with outer cover, due to outer cover and drive plate snap-fit engagement, outer cover band nutating disk rotates, and makes drive plate by transmission of power to free wheel device, roller in free wheel device is in clamped condition, by transmission of power to raceway post, then pass to transmission main shaft by raceway post, wheel is operated.When needs are shifted gears, unclamp throttle, under effect of inertia, wheel and transmission main shaft still keep High Rotation Speed, raceway post is greater than the rotating speed of outer cover with the rotating speed that transmission main shaft rotates, roller in free wheel device is in relaxation state, the transmission of power between free wheel device and raceway post is cut off, now can carries out gear shift operation very like a cork.
As can be seen here, not only structure is simple, component are few in the present invention, be easy to assembling, cost of production is low, and gear shift operation is without Clutch Control, makes gearshift more convenient, light, particularly when motorcycle downhill running, can also play the effect of fuel-economizing.
Described free wheel device (4) is positioned between the end wall of outer cover (2) and drive plate (3), and each like this part fits is tight, the space in outer cover effectively can be utilized to arrange, make more compact structure.
In order to improve the convenience of assembling further, and guarantee to connect firm, end face and the drive plate (3) of described free wheel device (4) outer ring fit, and are fixed together by circumferentially equally distributed bolt.
Beneficial effect: existing clutch housing combination and free wheel device combine by the present invention dexterously, automatically clutch function can be realized, make gear shift operation simpler, light, have design ingenious, implement easily, transformation easily, the feature such as low, the fuel-economizing of reforming cost and good reliability, all applicable in polytype motorcycle engine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, the driven gear 1 be fixed together and outer cover 2 are the component of the external combination of existing clutch, and therefore not to repeat here for its structure.The ring wall of outer cover 2 has multiple circumferentially equally distributed breach 2a, and drive plate 3 is provided with in outer cover 2, the excircle of this drive plate 3 is formed with circumferentially equally distributed external tooth, breach 2a one_to_one corresponding on external tooth on drive plate 3 and outer cover 2, and the external tooth on drive plate 3 embeds in the corresponding breach 2a on outer cover 2, makes drive plate 3 and outer cover 2 snap-fit engagement.
As shown in Figure 1, free wheel device 4 is also provided with in outer cover 2, this free wheel device 4 is between the end wall and drive plate 3 of outer cover 2, end face and the drive plate 3 of free wheel device 4 outer ring fit, and are fixed together between free wheel device 4 and drive plate 3 by circumferentially equally distributed bolt.Described free wheel device 4 is set on raceway post 5, roller 4a in free wheel device 4 rolls with raceway post 5 and coordinates, have at the center of raceway post 5 can with the splined hole of transmission main shaft 6 spline fitted, raceway post 5 is sleeved on transmission main shaft 6 by the splined hole at its center.
Working principle of the present invention is as follows:
The moment of torsion of crankshaft of motorcycle transmission is transferred to driven gear 1 through driving gear, driven gear 1 is rotated together with outer cover 2, due to outer cover 2 and drive plate 3 snap-fit engagement, outer cover 2 is with nutating disk 3 to rotate, make drive plate 3 by transmission of power to free wheel device 4, the roller 4a in free wheel device 4 is in clamped condition, by transmission of power to raceway post 5, pass to transmission main shaft 6 by raceway post 5 again, wheel is operated.When needs are shifted gears, unclamp throttle, under effect of inertia, wheel and transmission main shaft 6 still keep High Rotation Speed, raceway post 5 is greater than the rotating speed of outer cover 2 with the rotating speed that transmission main shaft 6 rotates, roller 4a in free wheel device 4 is in relaxation state, the transmission of power between free wheel device 4 and raceway post 5 is cut off, now can carries out gear shift operation very like a cork.
Above-mentioned free wheel device is existing mature technology, and therefore not to repeat here for its structure and working principle.
