Abstract
The utility model relates to the field of clutch, especially relates to a friction plate of a wet type clutch. The friction plate is an annular steel plate with a plurality of protruding teeth distributed on the inner circumference or the outer circumference, and the friction plate is an annular steel plate with axial elastic deformation which is 0.2 to 2mm, and the axial end surface is curved surface, the thickness of the friction plate is 0.5 to 2mm. when the driving and the driven friction plates are separated in the clutch, the utility model can eliminate oil adhesion between the driving and the driven friction plates, guarantee the thorough separation of the friction plates, and improve the working reliability of the clutch.
Description
Technical field
The utility model relates to clutch field, particularly a kind of friction plate of wet clutch.
Background technique
The employed clutch of motorcycle engine adopts wet clutch more 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, dispels the heat.Existing friction plate all is that the employing axial end is the rigidity friction plate of straight board plane shape, 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, cut off transmitting torque, cut off transmission of power.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, it is not thorough that the machine oil that active friction plate, driven Friction Disk Surface are adhered to forms the bonding clutch separation that causes when being adjacent to, or the segregation lag phenomenon appears, influence the separation of clutch.
Summary of the invention
At above-mentioned technical problem, the purpose of this utility model provides a kind of friction plate of wet clutch, and driving and driven friction plate is when clutch separation, and the machine oil that can eliminate between the driving and driven friction plate is bonding, guarantee to separate between the friction plate thoroughly, improve the reliability of clutch work.
The purpose of this utility model is achieved in that friction plate is the ring steel disc, be laid with a plurality of double wedges on its inner circumference or the excircle, described friction plate is the ring steel disc with axial elasticity amount of deformation, the axial elasticity amount of deformation of described friction plate is 0.2～2mm, its axial end is made as curved surface, and the thickness of described friction plate is 0.5～2mm.
The axial end of described friction plate is dish-shaped curved surface.
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, when this friction plate 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, can guarantee 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 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 utility model is described in further detail below in conjunction with drawings and Examples.
