Abstract
A clutch friction plate comprises a steel core plate and friction material face sheets arranged on the upper and the lower surfaces of the steel core plate, wherein a plurality of pairs of fixed holes are uniformly distributed on the steel core plate, riveting holes which correspond to the fixed holes are arranged on the friction material face sheets, the friction material face sheets are riveted on the steel core plate through the riveting holes and the fixed holes, the upper and the lower surfaces of the friction material face sheets are provided with lattice oil clearances, since the lattice oil clearances are formed on the friction material face sheets, the friction heat and dust can be removed in time, the friction between the friction material face sheets is reduced, the service life is prolonged, and the relative sliding between the friction material face sheets is further reduced. The steel core plate is riveted with the friction material face sheets, and thereby the use performance of the clutch friction plate is improved.
Description
(1) technical field
The utility model relates to a kind of friction plate, especially relates to a kind of clutch friction plate that is used for mechanical transmission.
(2) background technique
As everyone knows, the effect of clutch friction plate is a transmitting torque.It is made up of steel core plate and friction lining face, and friction lining face adopts adhesive method to invest on the steel core plate upper and lower surface.When carrying out friction driving, the upper and lower surface of friction lining face produces a large amount of heats in friction, can cause friction lining face surperficial overheated and damage, thereby has influence on the working life of whole friction clutch; On existing friction lining face, offer radially, the different groove of parallel or square formula, increasing friction factor, and help the lubricant oil circulation, obtain favorable cooling effect, though this design proposal has certain effect to reducing surface temperature.But because friction lining face frequently contacts, easily produce a large amount of frictional heats and powder, general groove is in time to discharge from the friction surface of clutch friction plate, makes the friction surface quick abrasion of clutch friction plate.When friction lining face damages and can only change whole clutch friction plate, and also can only together go out of use for intact steel core plate.
(3) summary of the invention
There is above-mentioned deficiency in order to overcome prior art, the utility model provides a kind of clutch friction plate, its friction material dough sheet can be changed use, simultaneously in the process of friction surface combination, can discharge frictional heat and powder in a large number, reduce the wearing and tearing of the friction surface of clutch friction plate, increase working life.
The technical scheme in the invention for solving the technical problem is: a kind of clutch friction plate, form by steel core plate and the upper and lower two lip-deep friction material dough sheets that are arranged at described steel core plate, uniform several on the described steel core plate to fixed hole, described friction material dough sheet is provided with the riveted holes relative with described fixed hole, described friction material dough sheet is riveted on the described steel core plate by described riveted holes and fixed hole, and the upper and lower surface of described friction material dough sheet is provided with oil clearance.
Described oil clearance is the trellis oil clearance, by tilt along the dextrorotation veer and and the steel core plate forms between radially angle the gap and along be rotated counterclockwise the direction inclination and and the steel core plate gap that forms angle between radially interlace and form.
Described angle can be 45～60 °.
Described friction material dough sheet can be asbestos-free friction material, also can be powder metallurgy sintered material.
Because described friction material dough sheet is riveted on the described steel core plate by described riveted holes and fixed hole, after the friction material dough sheet is worn, the rivet of dismantling is riveted on new friction material dough sheet on the described steel core plate by described riveted holes and fixed hole.So not only convenient but also saved friction plate.
Because the gap on the friction material dough sheet tilts to sense of rotation, this friction material dough sheet when rotated, lubricant oil can not be thrown out of, but under the effect of tangential force, entad flow along oil clearance, the oil of the oil clearance on the friction material dough sheet will get more and more, and friction material dough sheet and steel core plate are played sufficient cooling and lubrication, reduce the wearing and tearing of friction material dough sheet, effectively avoided skidding of clutch.Simultaneously, because the oil clearance on the friction material dough sheet is the trellis oil clearance,, all can play cooling and antiwear effect no matter be main story or counter-rotating.
The beneficial effects of the utility model are: owing to form the trellis oil clearance on the upper and lower surface of friction material dough sheet, frictional heat and dust in time can be got rid of, reduce friction wearing and tearing between the material dough sheet prolong its working life, have also reduced the slide relative between the friction material dough sheet.Described steel core plate is riveted mutually with the friction material dough sheet, has improved its usability.
(4) description of drawings
Fig. 1 is a plan view of the present utility model.
Fig. 2 is a sectional view of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
According to a kind of clutch friction plate illustrated in figures 1 and 2, it mainly is made up of steel core plate 1 and the upper and lower two lip-deep friction material dough sheets 2 that are arranged at described steel core plate 1, uniform several on the described steel core plate 1 to fixed hole 3, described friction material dough sheet 2 is provided with the riveted holes 4 relative with described fixed hole 3, described friction material dough sheet 2 is riveted on the described steel core plate 1 by described riveted holes 4 and fixed hole 3, and the upper and lower surface of described friction material dough sheet 2 is provided with oil clearance.
Described oil clearance is the trellis oil clearance, by tilt along the dextrorotation veer and and steel core plate 1 forms between radially angle the gap and along be rotated counterclockwise the direction inclination and and steel core plate 1 gap that forms angle between radially interlace and form.
Described angle can be 45～60 °.
Described friction material dough sheet 2 can be asbestos-free friction material, also can be powder metallurgy sintered material.
Because described friction material dough sheet 2 is riveted on the described steel core plate 1 by described riveted holes 4 and fixed hole 3, after friction material dough sheet 2 is worn, the rivet of dismantling is riveted on new friction material dough sheet 2 on the described steel core plate 1 by described riveted holes 4 and fixed hole 3.So not only convenient but also saved friction plate.
Because the gap on the friction material dough sheet 2 tilts to sense of rotation, this friction material dough sheet 2 when rotated, lubricant oil can not be thrown out of, but under the effect of tangential force, entad flow along oil clearance, the oil of the oil clearance on the friction material dough sheet 2 will get more and more, and friction material dough sheet 2 and steel core plate 1 are played sufficient cooling and lubrication, reduce the wearing and tearing of friction material dough sheet 2, effectively avoided skidding of clutch.Simultaneously, because the oil clearance of friction material dough sheet 2 is the trellis oil clearance,, all can play cooling and antiwear effect to friction material dough sheet 2 no matter be main story or counter-rotating.
