Abstract
The utility model provides a kind of high revolving speed friction element, belongs to wet friction clutch friction element field.Described chip (1) outer ring is machined with spline (3), on 6 positions that spline (3) is distributed uniformly and circumferentially, remove a spline tooth (4) respectively, sintering is provided with helical oil groove (5) and radial oil groove (6) on the metal friction layer (2) on chip (1) surface, the radial oil groove (6) penetrates through frictional layer (2), radial oil groove (6) rotation direction on described frictional layer (2) two sides is consistent, that is, chip (1) two sides radial direction oil groove (6) is in the same size close to the hole tangent line of interior nose end and radial oil groove (6) stretching angular separation.The utility model structure is simple, effectively reinforcement lubricant effect, reduces fever and with row's effect.
Description
Technical field
The present invention and wet friction clutch friction element field, specifically a kind of high revolving speed friction element.
Background technique
Wet friction clutch is a kind of controllable clutch device that torsion pass is carried out using friction element, and torque transmission capacity is strong, answers
With extensive.There are inherent shortcomings for wet friction clutch, i.e., in clutch off the row, exist between friction element and relatively rotate,
Shearing effect is caused to the lubricating oil in adjacent friction element gap, by newton module, shearing effect will lead to fever
With the generation with row's phenomenon, revolving speed is higher, and fever is more obvious with row's phenomenon, causes wet friction clutch in high revolving speed occasion
Application be extremely limited.
Summary of the invention
The purpose of the present invention is to solve the above-mentioned problems of the prior art, and then provide a kind of for wet friction
The high revolving speed friction element of clutch, the band row that can reduce wet friction clutch and heating effect, improve wet friction clutch
Device is applicable in the upper limit of revolving speed.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of high revolving speed friction element, including the metal friction layer being sintered on chip and its both side surface, the chip
Outer ring is machined with spline, on 6 positions that spline is distributed uniformly and circumferentially, removes a spline tooth respectively, sintering exists
Helical oil groove and radial oil groove are provided on the metal friction layer of chip surface, the radial oil groove penetrates through frictional layer, described
Radial oil groove rotation direction on frictional layer two sides is consistent, that is, chip two sides radial direction oil groove is close to the hole tangent line and radial direction of interior nose end
It is in the same size that oil groove stretches out angular separation；
The radial oil groove is evenly distributed；
The radial oil groove bottom has rounded structure.
The beneficial effects of the present invention are: by using technical solution of the present invention, in radial oil groove rotation direction and friction clutch
Device turns under unanimous circumstances, and the lubricating oil in adjacent friction element gap can be discharged rapidly, effectively reinforcement lubricant effect, drop
Low fever improves the applicable revolving speed upper limit of wet friction clutch with row's effect.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of A-A section of the present invention.
Fig. 3 is the structural schematic diagram of B-B section of the present invention.
Fig. 4 is lubricating oil velocity vector schematic diagram.
Specific embodiment
Below in conjunction with attached drawing, the present invention is described in further detail: the present embodiment is being with technical solution of the present invention
Under the premise of implemented, give detailed embodiment, but protection scope of the present invention is not limited to following embodiments.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of high revolving speed friction element involved in the present embodiment, including chip 1 and its two
The metal friction layer 2 being sintered on side surface, 1 outer ring of chip are machined with spline 3, along the circumferential direction uniformly divide in spline 3
On 6 positions of cloth, remove a spline tooth 4 respectively, sintering is provided with helical oil groove 5 on the metal friction layer 2 on 1 surface of chip
With radial oil groove 6, the radial oil groove 6 penetrates through frictional layer 2,6 rotation direction one of radial oil groove on 2 two sides of frictional layer
It causes, that is, 1 two sides radial direction oil groove 6 of chip is in the same size close to the hole tangent line of interior nose end and the radial stretching of oil groove 6 angular separation；
The radial oil groove 6 is evenly distributed；
6 bottom of radial oil groove has 7 structure of fillet.
As shown in figure 4, in the case where radial 6 rotation direction of oil groove and friction clutch turn to n unanimous circumstances, between adjacent friction element
Lubricating oil stress in gap generates radial velocity vectorWith circumferential speed vector, the two speed resultant vectorWith radial oil groove 6
Direction is consistent, and lubricating oil is discharged rapidly, effectively reinforcement lubricant effect, to reduce fever with row's effect, improves
The applicable revolving speed upper limit of wet friction clutch.
The foregoing is only a preferred embodiment of the present invention, these specific embodiments are all based on the present invention
Different implementations under general idea, and scope of protection of the present invention is not limited thereto, it is any to be familiar with the art
Technical staff in the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of, should all cover of the invention
Within protection scope.Therefore, the scope of protection of the invention shall be subject to the scope of protection specified in the patent claim.
