Abstract
The utility model discloses a motorcycle clutch buffer structure. The motorcycle clutch buffer structure comprises a housing (1) and a gear (2), wherein the gear (2) is flatly mounted on an end plate of the housing (1), 2-4 limiting bosses (3) are formed on the end plate of the housing (1) in an integrally protruding mode, arc-shaped holes (4) in one-to-one correspondence with the limiting bosses (3) are formed in a gear disc of the gear (2), the limiting bosses (3) extend into the middle portions of the corresponding arc-shaped holes (4), and holes in the two ends of each arc-shaped hole (4) in the circumferential direction are filled with buffer blocks (5). According to the motorcycle clutch buffer structure, the limiting bosses on the housing of a clutch, the arc-shaped holes in the gear and the buffer blocks in the arc-shaped holes are matched to form the buffer structure, stable buffering capacity is provided for synchronous rotation of the housing and the gear, resonance and abnormal sounds cannot be produced in the buffering process, as a result, the operational stability of the whole clutch is improved, and the service life of the whole clutch is prolonged.
Description
Technical field
The utility model belongs to technical field of motorcycles, specifically, and particularly a kind of buffer structure of clutch of motorcycle.
Background technique
In existing clutch of motorcycle, between case and gear, adopt spring as buffer medium, because the natural length of spring and the flute length of dashpot reach and can not coincide completely, impact in buffering is larger, buffering easily causes resonance, produce abnormal sound, thereby reduce working life and the using effect of clutch.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of clutch of motorcycle buffer structure little, good buffer effect that impacts.
The technical solution of the utility model is as follows: a kind of clutch of motorcycle buffer structure, comprise case (1) and gear (2), in one end of described case (1), be formed with out the end plates of center hole, described gear (2) paperback is on the end plates of case (1), on the end plates of described case (1), one is protruded and is formed with 2-4 positive stop lug boss (3), and these positive stop lug boss (3) are uniformly distributed around the center hole of case (1) end plates; On the fluted disc of described gear (2), have and positive stop lug boss (3) arcuate socket (4) one to one, described positive stop lug boss (3) extend into the middle part of arcuate socket (4), and be all filled with buffer stopper (5) at the two ends of arcuate socket (4), these two buffer stoppers (5) occupy the both sides of positive stop lug boss in same hole (3), and two buffer stoppers (5) and the positive stop lug boss (3) of each arcuate socket (4) assembling corresponding to it form an elastic buffer position-limiting unit together.
Adopt above technological scheme, by protruding on the end plates at clutch case, form 2-4 positive stop lug boss, these positive stop lug boss extend into respectively in arcuate socket corresponding on gear, and slide and fill two buffer stoppers in arcuate socket, these two buffer stoppers all form elastic spacing at the two ends of positive stop lug boss, and such arcuate socket, two buffer stoppers and a positive stop lug boss have just formed a compact slip buffer cell.Between whole case and gear, be formed with the slip buffer cell of 2-4, these slip buffer structures are evenly distributed on same circumference, can provide and rotate stably damping of shocks ability.During work, no matter the rotating speed of gear is fast or slow if being compared with the rotating speed of case, and positive stop lug boss all can be carried out elastic spacing and in sliding process, absorb the impact between gear and case by the buffer stopper in corresponding orientation.Because buffer stopper is compared to damping spring, on the one hand owing to also can not producing noise and abnormal sound in the deformation process of buffer stopper, buffer stopper is filled in arcuate socket on the other hand, the assembling of buffer stopper and arcuate socket is comparatively compact, impact in buffering course attracts comparatively quick, so in buffering course, neither can form resonance, also can not produce mechanical abnormal sound.Simultaneously, the buffer structure of clutch provides buffer space for the task driven between clutch gear and external tooth, avoid producing impact endurance test shock and abnormal sound in the synchronizing process of clutch gear and external tooth He in clutch working procedure, improved whole clutch traveling comfort and working life.
Described buffer stopper (5) is suitable with the shape of arcuate socket (4) end, buffer stopper (5) coordinates with positive stop lug boss (3) plane contact, this positive stop lug boss (3) is fan-shaped, and the inside and outside circle cambered surface of positive stop lug boss (3) is suitable with the corresponding hole wall of arcuate socket (4).
Buffer stopper and arcuate socket end form suitable, can improve the assembling compactedness between buffer stopper and arcuate socket, make arcuate socket hole wall stressed relative even in extrusion process with buffer stopper, the stationarity while improving work.Buffer stopper coordinates with positive stop lug boss plane contact, can make like this buffer stopper and positive stop lug boss when buffering, active force is born by whole plane, the mean forced in face territory, in buffering course, the mobile extruding of positive stop lug boss and buffer stopper steadily, further improves the effect of buffering.The inside and outside circle cambered surface of positive stop lug boss is suitable with the corresponding hole wall of arcuate socket, can improve compactedness that positive stop lug boss coordinates with arcuate socket and positive stop lug boss mobile precision in arcuate socket, make the slip of positive stop lug boss in arcuate socket more smooth and easy and steady, improve cushioning effect of the present utility model.
Due to rubber material draw materials and shaping operation all than being easier to, and there is good elastic performance and longer working life, so described buffer stopper (5) is elastic caoutchouc material.
The quantity of arcuate socket and positive stop lug boss does not have enough distribution spaces too much, and the circumferential lengths of each arcuate socket and fan-shaped angle compressed, its cacheable surplus also can be compressed, affects the cushioning effect of buffer structure; The group number of buffer structure is less very little for the quantity of arcuate socket and positive stop lug boss, also can weaken cushioning effect, so, the quantity of described arcuate socket (4) and positive stop lug boss (3) is three, both can make full use of the space of gear, guarantee the surplus of buffering, good cushioning effect was also provided.
Owing on boss, cover plate will being installed, if assembling rear boss is lower than gear, cover plate will be pressed on gear so, when gear and case form buffering rotation, cover plate will form serious friction with gear, both cover plate and gear were formed to loss, and also can affect the usability of clutch, so the large 0.1-0.3mm of fluted disc thickness of the aspect ratio gear (2) of described positive stop lug boss (3).
In the outer end of described positive stop lug boss (3), be stamped cover plate (6), this cover plate (6) covers the region, dead ahead of arcuate socket (4) place circumference, and cover plate (6) is fixing with positive stop lug boss (3).After the outer end cap upper cover plate of positive stop lug boss, the region, dead ahead of cover plate lid post arcuate socket place circumference, cover plate just can seal the aperture of arcuate socket so, while preventing buffer stopper work, extrudes or drop out from arc aperture.
On the end face of described positive stop lug boss (3), have tapped hole (7), screw passes the via hole on cover plate (6) and is locked in tapped hole (7).Cover plate is fixed by screws on positive stop lug boss, compares traditional riveted joint and directly rivets assembling, has disassembling, assembling and replacing advantage flexibly.
Beneficial effect: the utility model is with the positive stop lug boss on clutch case, arcuate socket on gear and the buffer stopper in arcuate socket coordinate formation buffer structure, for the synchronous rotation of case and gear provides buffer capacity stably, can in buffering course, not produce resonance and abnormal sound, also avoid producing impact endurance test shock and abnormal sound in the synchronizing process of clutch gear and external tooth He in clutch working procedure, improved whole clutch traveling comfort and working life.
