Abstract

The utility model discloses a center sleeve for manually disengaging and engaging motorcycle clutches. The center of the center sleeve is provided with an inner spline hole which is connected with a main shaft, the external wall of the center sleeve is provided with external teeth for installing a steel sheet and a pressure disk, and the end face of the center sleeve is distributed with holes which are connected with connecting columns of the pressure disk along the circumference. The utility model has the improved points that the sleeve edge at the bottom of the center sleeve or the wall of an inner cavity is provided with an oil groove, and the oil groove is communicated till a tooth groove of the external teeth of the center sleeve to form an oil path. One the premise that the service strength and the normal function of a clutch are ensured, the utility model can ensure the oil path of the clutch to be unblocked, and heat dissipation is good.

Description

A kind of central sleeve of manual clutch clutch of motorcycle

Technical field

The utility model belongs to the clutch of motorcycle technical field, is specifically related to a kind of central sleeve structure that is applicable to the manual clutch clutch of motorcycle.

Background technique

The manual clutch clutch of motorcycle generally comprises outer cover combination and central sleeve combination two parts, with 125 type manual clutch clutch of motorcycle is example, its structure is referring to Fig. 4, the outer cover combination is by outer cover 1, driven gear 2, cushion collar 3, cover plate 4, rivet 5 is riveted together, the central sleeve combination is by platen 6, friction plate 7, steel disc 8, central sleeve 9, spring 10, lift slab 11, bolt 12 tightens together by pre-pressure of the spring, outer cover combination (connection of outer cover internal spline) is contained on the starter receiver, the starter receiver sky is enclosed within on the engine spindle, and central sleeve combination (connection of central sleeve internal spline) directly is contained on the engine spindle.During clutch work, driving gear drives the outer cover combination by driven gear and rotates, and the outer cover combination drives the central sleeve combination by the outer cover blade and rotates, and the central sleeve combination drives main shaft by the pre-pressure of the spring transmitting torque and rotates; When hand is pinched clutch handle, after the clutch separation, the outer cover combination is dallied on main shaft together with starter receiver, realizes the effect of clutch shift, transmitting torque, overload protection.In these clutches, to the lubricated of friction plate mainly is splash lubrication, the some that is clutch is immersed in the lubricant oil, relies on the clutch rotation to stir lubricant oil and be lubricated, but this is often not enough, when clutch when running up, if driver and passenger's misoperation (half-clutch use is too much) or overload, cltuch slipping (friction plate relative movement) because clutch lubrication, heat radiation are bad, causes friction plate to be ablated easily.

Summary of the invention

The purpose of this utility model is the problems referred to above at the prior art existence, a kind of central sleeve of manual clutch clutch of motorcycle is provided, under the prerequisite that the working strength that guarantees the clutch core cover, normal function are realized, for lubricated, heat radiation between the friction plate provide unimpeded oil circuit, improve the heat dispersion of clutch, thereby avoid friction plate to ablate.

The technical solution of the utility model is: keeping under the constant condition of existing central sleeve structure, offering oil groove on the cover edge bottom central sleeve or the wall of inner chamber, and making the teeth groove on this oil groove connection central sleeve outer wall.Oil groove is preferably the rectangle oil groove, and on inner ring evenly distribution 2-10 be good.

Owing to adopt the structure of setting up oil groove, can be with the teeth groove on the lubricant oil guiding centre cover outer wall, and further distribute to by teeth groove and be assemblied in the outer friction plate of central sleeve, so just make and obtain good lubricated and heat radiation between the friction plate by this unimpeded oil circuit, make clutch when user's misoperation or overload are skidded, can avoid friction plate ablated, improve traveling security.

The manual clutch clutch of motorcycle that the central sleeve structure that the utility model relates to can be widely used in various models uses, as 200 types, 150 types, 125 types, 100 types, 90 types etc.

Description of drawings

Fig. 1 is the structural drawing of the central sleeve that provides of the utility model;

Fig. 2 is the A-A sectional drawing of Fig. 1;

Fig. 3 is the rear view of Fig. 1;

Fig. 4 has been to use the structural drawing of 125 type manual clutch clutch of motorcycle of this central sleeve structure.

Embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, the central sleeve structure of this clutch is such: the inner flower-key hole 9-1 of central sleeve is used for being connected with main shaft, the central sleeve outer wall has the external tooth 9-2 that steel disc and platen are installed, the central sleeve end face circumferentially has the hole 9-3 that is connected with the attachment post of platen (what present embodiment showed is four hole structures, but it also can be structures such as five holes, six holes, seven apertures in the human head or octal).The core of this architecture advances be cover in central sleeve bottom along the oil groove 9-5 that opens four rectangles on the 9-4, they all are communicated with the teeth groove 9-7 of the external tooth of central sleeve, form oil circuit, to play the effect to friction plate conveying lubricant oil.

Certainly according to actual needs, oil groove 9-5 also can be opened on the wall 9-6 of central sleeve inner chamber, and can cover along on or evenly distribute 2,5,6,8,10 etc. on the wall of chamber, unimpeded to reach oil circuit, sufficient lubrication is a purpose.

Fig. 4 is that this central sleeve structure is used the concrete state on 125 type manual clutch clutch of motorcycle, the outer cover combination of this clutch is by outer cover 1, driven gear 2, cushion collar 3, cover plate 4, rivet 5 is riveted together, the central sleeve combination is by platen 6, friction plate 7, steel disc 8, central sleeve 9, spring 10, lift slab 11, bolt 12 tightens together by pre-pressure of the spring, outer cover combination (connection of outer cover internal spline) is contained on the starter receiver 13, the starter receiver sky is enclosed within on the engine spindle 14, and central sleeve combination (connection of central sleeve internal spline) directly is contained on the engine spindle 14.As can be seen from the figure, central sleeve 9, is communicated with the teeth groove 9-7 of the external tooth of central sleeve along having opened oil groove 9-5 on the 9-4 at the cover of its bottom, has formed oil circuit.

Claims

1, a kind of central sleeve of manual clutch clutch of motorcycle, there is the inner flower-key hole (9-1) that is connected with main shaft at the central sleeve center, have on the outer wall of central sleeve on the external tooth (9-2) that steel disc and platen are installed, the central sleeve end face circumferentially has the hole (9-3) that is connected with the attachment post of platen; It is characterized in that: the cover in the central sleeve bottom upward or on the wall (9-6) of inner chamber is offered oil groove (9-5) along (9-4), and oil groove is communicated to the teeth groove (9-7) of central sleeve external tooth, forms oil circuit.

2, central sleeve according to claim 1 is characterized in that: described oil groove is the rectangle oil groove, cover along on or on the wall of inner chamber evenly distribution 2-10.
