Description
Technical field
The present invention relates to clutch field, particularly a kind of friction plate of wet clutch.
Background technique
The employed clutch of motorcycle engine mostly is wet clutch at present, and this wet clutch is to be immersed in the machine oil environment to work, and can rely on machine oil to reduce wearing and tearing, takes away heat.This wet clutch generally is provided with many group friction plates, contacts transmitting torque, the formation transmission of power by the active friction plate of many groups friction plate with axial end from movable friction plate; Active friction plate by many groups friction plate with interrupt the moment of torsion transmission from separating of movable friction plate, cut off transmission of power.And existing friction plate all is that the employing axial end is the rigidity friction plate of straight pull, during clutch, active friction plate contacts transmitting torque by whole end face to axial translation formation face with axial end from movable friction plate, during clutch separation, active friction plate contacts by whole end face with face from the axial end of movable friction plate and separates to axial translation, the interrupt delivery moment of torsion cuts off transmission of power.But because wet clutch is to be immersed in the machine oil environment to work, when clutch separation, owing to active friction plate and from movable friction plate is the face unpack format, the machine oil that active friction plate, driven Friction Disk Surface are adhered to forms adhesion when being adjacent to and causes clutch separation not thorough, or the segregation lag phenomenon appears, influence the separation of clutch.Particularly in the winter of cold, because temperature is lower, engine oil viscosity increases, and in use, the halfway phenomenon of Wet-type multi-disc formula clutch separation is particularly serious, causes the control of travelling of motorcycle to have some setbacks.
Summary of the invention
The objective of the invention is deficiency at the friction plate existence of existing wet clutch, a kind of friction plate with wet clutch of axial elasticity amount of deformation is provided, it can eliminate the machine oil adhesion between the friction plate when clutch separation, guarantee to separate thoroughly between the friction plate.
The object of the present invention is achieved like this: friction plate is the ring steel disc, is laid with a plurality of circumferentially fixing double wedges that are used on its inner circumference or the excircle, and described friction plate is the ring steel disc with axial elasticity amount of deformation, and its axial end is made as curved surface.
Owing to adopted such scheme, it is curved surface that friction plate is made as axial end, be ring steel disc with axial elasticity amount of deformation, working as this friction plate like this contacts with another friction plate under the positive pressure of the platen of clutch, this friction plate produces the axial elasticity distortion and is driven plain under pressure, formation contacts with the face of the axial end of another friction plate, fully guarantees the friction area of friction pair, transmitting torque; When the positive pressure that this friction plate is granted is eliminated, this friction plate reverts to axial end under the resiliently deformable effect of self be the curved surface prototype, oil film adhesion between elimination and another friction plate, making between the friction pair is the line contact, guarantees can thoroughly separate apace between this friction plate and another friction plate.
The thickness of described friction plate is 0.5～2mm, can guarantee like this can produce resiliently deformable by the ring friction plate that the sheet metal punching press is made under the pressure of the platen of clutch; And friction plate axial elasticity amount of deformation is 0.2～2mm, and the axial elasticity amount of deformation that can guarantee friction plate can excessively not occupy the axial space of clutch, to satisfy the design principle of clutch miniaturization in this scope.
The structure of friction plate of the present invention and making are all extremely simple, friction plate of the present invention is assemblied on the wet clutch uses, can solve the long-standing active friction plate of wet clutch and when separating, cause the halfway problem of clutch separation because of the machine oil adhesion from movable friction plate.
The invention will be further described below in conjunction with drawings and Examples.
