Description
Technical field
The utility model relates to a kind of clutch, relates in particular to the manual front-located mode friction clutch of a kind of motorcycle.
Background technique
At present, the manual front-located mode clutch that motorcycle uses is installed on the bent axle, mainly comprises driving disc, outer cover, active friction plate, from movable friction plate, upper plate, gear cover and driving gear.Driving disc is connected with the bent axle spline, driving disc is installed in the outer cover near bottom position, between outer cover bottom end face and driving disc, be provided with compressed marshall springs, because the rebounding force of marshall springs, driving disc is pressed towards driving and driven friction plate all the time, there is upper plate outer end at friction plate by the back-up ring axial restraint, thereby makes driving and driven friction plate under normal conditions in conjunction with compressing.The active friction plate sky is enclosed within on the gear cover, its external tooth axial slide on the outer cover of packing into, and can in chute, move; Match with gear cover from the internal tooth of movable friction plate, and can move along the axial direction of gear cover, the gear cover sky is enclosed within on the driving disc, and the internal tooth that gear cover has is meshed with driving gear.During normality, because the effect of marshall springs makes the driving disc end face that driving and driven friction plate is compressed, friction pair engages in running order, and the transmission of power of motor is in proper order: bent axle → driving disc → outer cover → active friction plate → and from movable friction plate → gear cover → driving gear.During clutch separation, by external force pushing outer cover, make marshall springs be continued compression, the distance between driving disc and the upper plate increases at this moment, makes between driving and driven friction plate the gap to occur, and friction pair is in disengaged condition, and power is cut off.In the transmission and separation process of moment of torsion, the external tooth of active friction plate often produces bump to the axial slide on the outer cover, and outer cover is the aluminium alloy compression casting moulding, surface hardness is low, chute produces dentation easily at the bump place concavo-convex, cause catching phenomenon occurring between active friction plate external tooth and the outer cover chute, make clutch in conjunction with the time skid, produce abnormal sound, not thorough during clutch separation.In addition, traditional friction pair is initiatively or from movable friction plate at the end face of rigidity lamellar body brake pad to be set, brake pad adopts non-metallic friction materialss such as bakelite to make usually, be fixed on the friction plate lamellar body by modes such as adhesive bonding or die casting, and with contacted another friction plate of this friction plate be steel disc, this kind friction plate at high temperature easily wears out, hardens, and also can burn when serious; And the oil film between friction plate is easy to generate parital vacuum, cause friction plate in conjunction with the time closely easily do not skid, being stained with again during separation and stagnate to be difficult for throwing off.Thereby the traditional friction clutch of this kind not only influences operator's comfortable feel, the more important thing is to have potential safety hazard, very easily causes traffic accident.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of manual front-located mode friction clutch, its outer cover hardness height, shock-resistant; Friction plate is high temperature resistant, be difficult for burning.
The technical solution of the utility model is as follows: a kind of manual front-located mode steel cage friction clutch, comprise driving disc, outer cover, active friction plate, from movable friction plate, upper plate and gear cover, wherein the external tooth of driving disc matches with the chute of outer cover, driving and driven friction plate is staggered to be folded between driving disc and the upper plate, the external tooth of active friction plate matches with the chute of outer cover, match with the external tooth of gear cover from the internal tooth of movable friction plate, it is characterized in that: described outer cover and driving and driven friction plate are made by steel material.Because outer cover is made by steel material, the hardness height is shock-resistant, and steel friction plate thermal conductivity is good, makes friction plate be difficult for burning, also can utilize heat treatment process such as case-carbonizing, nitriding, quenching further to improve the wear resistance of friction plate easily, be improved the working life of friction plate.
As preferably, described active friction plate is provided with the groove that distributes and axially connect along circumferentially at the inner circumference place.Axial pass trough is beneficial to lubricant oil engaging friction face, plays effect lubricated, that cool off and dispel the heat; Simultaneously the groove edge also can strike off unnecessary lubricant oil, makes rubbing surface can not produce parital vacuum because of the existence of oil film, rubbing surface in conjunction with the time closely non-slip, thoroughly rapid during separation.
As preferably, it is relative with the middle continuous circular shape plane from the movable friction plate end face that described active friction plate end face is provided with the planar annular of inside groove.Like this, be beneficial to lubricated, cooling, heat radiation and frizing from the movable friction plate rubbing surface.
As preferably, describedly also can be provided with the groove that distributes and axially connect along circumferentially at excircle from movable friction plate.
As preferably, the described planar annular that is provided with water jacket from the movable friction plate rubbing surface is relative with the middle continuous circular shape plane on the active friction plate rubbing surface.
As preferably, described active friction plate or evenly distribute by circumference on end face from movable friction plate and to protrude from this end face, and the friction boss of making by steel material.These protrude from the boss of end face, though reduced friction area, have increased the positive pressure on the unit area, and help preventing the hot generation of skidding and reduce friction.
The beneficial effects of the utility model are: outer cover hardness height, shock-resistant; The friction plate thermal conductivity is good, be difficult for burning, wear resistance is strong, and in conjunction with the time be difficult for skidding, thoroughly rapid during separation; The clutch bulk life time improves.
