Description
Technical field
The utility model relates to a kind of clutch, particularly a kind of clutch that is used on the motorcycle.
Background technique
The existing clutch that is used on the motorcycle has generally comprised case, platen, overcoat and central sleeve, is staggeredly equipped with friction plate and clutch-plate between overcoat and the platen.As shown in Figures 2 and 3, in present technology, the material that constitutes friction plate 5 is an aluminum alloy, its both sides are provided with the wear-resisting nonmetal wearing layer 8 of one deck, as rigid plastics, to form a lamination layer structure, the metallic material that constitutes clutch-plate 6 is an iron, because all very high and equal and opposite in direction of hardness of nonmetal wearing layer 8 and iron, the clutch that the friction plate of this structural type and clutch-plate constitute has the following disadvantages in use:
1, the nonmetal wearing layer on the friction plate is softer, form bigger friction factor with clutch-plate, guarantee the reliable delivery of power, still, nonmetal wearing layer poor heat resistance, vehicle is at buty shifting or when being in half-clutch state for a long time, and friction plate and clutch-plate cause nonmetal wearing layer abrasion distortion because of the high heat of friction-produced each other, even ablate, working life is extremely short, easily causes cltuch slipping, and the engine power transmission freely or at all can't not transmitted;
2, friction plate made of iron and clutch-plate are when mutual friction mutually, easily produce many relatively large iron filings of particle, after iron filings are sneaked into machine oil, easily make the too early inefficacy of machine oil, shorten the working life of machine oil, simultaneously, iron filings enter into engine interior with machine oil, easily cause motor locking, piston ring breakage and scuffing of cylinder bore;
In order to overcome above-mentioned deficiency, friction plate is made the single layer structure that is made of iron fully by the producer that has, though it has improved the performance of the thermal deformation resistant of friction plate, also strengthen simultaneously the wear resistance between friction plate and the clutch-plate, but because friction plate and clutch-plate all are fabricated from iron, hardness is identical and very high each other, make that between friction plate and the clutch-plate all are hard contacts, when vehicle is in gear shift or half-clutch state, the bigger impact that on clutch, can produce, this impact is delivered on gear shift pedal and the gear shifting handle, and operator's operation will be gruelling, and this brings great discomfort for the personnel of driving.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of wear-resisting property is good, long service life, manipulation is light, reliability is high is used for clutch on the motorcycle.
The purpose of this utility model is to realize by such technological scheme, it comprises case, platen, overcoat and central sleeve, be staggeredly equipped with friction plate and clutch-plate between overcoat and the platen, it is characterized in that: the hardness of metal materials that constitutes friction plate is different with the hardness of metal materials that constitutes clutch-plate.
In the utility model,, make both by original hard contact owing to adopted different friction plate of hardness and clutch-plate, change the soft or hard contact into, have certain flexibility each other, can form relative yielding, friction plate and clutch-plate are in relative rotary course, can obtain efficient buffer, not only greatly reduce abrasion, prolonged the life-span of clutch, and the clutch transmission of power also more steadily, reliably, no greater impact produces, and operation also becomes very light.
As a kind of optimal way, the metallic material that constitutes clutch-plate is an iron, and the metallic material that constitutes friction plate is the little aluminum alloy of hardness ratio iron.Because aluminum alloy hardness is relatively low, wear-resisting property is good, is fit to very much do high-abrasive material.What is more important, the hardness of the friction plate of making by aluminum alloy, it is little many that the clutch-plate that is fabricated from iron is wanted, make friction plate when pressure rotates, have certain flexibility with respect to clutch-plate, can form relative yielding, friction plate and clutch-plate are in that pressurized is relative when rotating, effectively cushioned, abrasion greatly reduces.Both are different hardness, and friction plate and the clutch-plate overall wear resistance under original high speed, high pressure and hot environment can be improved, and prolong at least 50 times working life, have improved the stability and the reliability of clutch greatly.Simultaneously, because the hardness of friction plate is less than the hardness of clutch-plate, both are very tiny Al alloy powders because of fricative abrasive material basically, though also can enter in the cylinder block with machine oil, but because their volume is very small, can not cause damage, and be filtered easily, can not pollute machine oil piston, bent axle etc.
As another kind of optimal way, the metallic material that constitutes clutch-plate is a Cuprum alloy, and the metallic material that constitutes friction plate is the big iron of hardness ratio Cuprum alloy.Its principle is the same, is not repeated in this description at this.
Simultaneously; friction plate hardness is less than clutch-plate; both are that very tiny aluminum alloy granule or copper gold closes particle because of fricative abrasive material basically; these impurity particles; though also can enter in the cylinder block,, can not cause damage to piston, bent axle etc. because their volume is very small with machine oil; and be filtered easily, can not pollute machine oil.
As the improvement of above-mentioned two kinds of optimal ways, a side or two sides of friction plate are provided with anti-slip tank, with the frictional force of further raising friction plate, make the clutch action of clutch more smooth and easy, and transmission of power is more reliable and more stable.
Owing to adopted technique scheme, the utility model has the advantages that: wear-resisting property is good, long service life, manipulation is light, reliability is high.
