Abstract
The utility model discloses a kind of Parabolic oil groove friction plate, the oil groove (1) of multiple parabolic shaped structures is equipped at intervals on the oil groove friction plate (2), and the depth of oil groove (1) is gradually increased from interior radial outer diameter.The rectangular cross-section structure of the oil groove (1), the oil groove friction plate (2) can apply in the double clutch gearboxes of wet type.The utility model is changed to Parabolic oil groove on the basis of not changing friction of wet clutch internal-and external diameter, by radial oil groove, and the depth of oil groove is gradually increased from internal diameter toward outer diameter, enables friction plate quick oil-discharging, and the cooling effect for keeping friction secondary is more preferable.
Description
Technical field
The utility model relates to a kind of friction plate more particularly to a kind of Parabolic oil groove frictions of wet clutch
Piece.
Background technique
The friction plate of wet clutch is all that tool is effigurate, its friction plate need to have clutch during the work time
The function of quick oil-discharging, and oil liquid can take away the heat of friction plate, play cooling effect.
As shown in Fig. 1, in figure, 1 is sump area, and 2 be oil groove friction plate.As shown in Fig. 2, oil liquid enters from right side
And exported from left side, during clutch rotation, the friction plate of the radial oil groove of the prior art occurs during oil extraction
The unsmooth problem of oil extraction, so that oil liquid backflow phenomenon is occurred.As shown in attached drawing 3 and attached drawing 4, by taking radial oil groove as an example, it is known that
For oil liquid under identical revolving speed, the radial velocity in oil groove area is much larger than the radial velocity in non-oil groove area, the oil film known to attached drawing 5
Thickness is bigger, and radial pressure is smaller, and therefore, influence of the structure of oil groove friction plate to oil groove oil extraction speed is very big.
Summary of the invention
The purpose of this utility model is to provide a kind of Parabolic oil groove friction plates, rub not changing wet clutch
On the basis of pad internal-and external diameter, radial oil groove is changed to Parabolic oil groove, and the depth of oil groove from internal diameter toward outer diameter gradually
Increase, enable friction plate quick oil-discharging, the cooling effect for keeping friction secondary is more preferable.
The utility model is realized in this way:
A kind of Parabolic oil groove friction plate, the oil groove friction plate are equipped with the oil of multiple parabolic shaped structures
Slot, and the depth of oil groove is gradually increased from interior radial outer diameter.
The rectangular cross-section structure of the oil groove.
The oil groove friction plate can apply in the double clutch gearboxes of wet type.
The utility model use with difference in height Parabolic friction plate, oil groove form be it is Parabolic, cut
Face shape be rectangle, the depth of oil groove from internal diameter toward outer diameter from develop when gradually increase, enhancing oil liquid from internal diameter toward outer diameter develop
When Differential pressure flow；Allow the faster oil extraction of the double clutch gearboxes of wet type, preferably cooling effect can be played for friction pair
Fruit.
The utility model is changed to parabola on the basis of not changing friction of wet clutch internal-and external diameter, by radial oil groove
The oil groove of type, and the depth of oil groove is gradually increased from internal diameter toward outer diameter, enables friction plate quick oil-discharging, the cooling for keeping friction secondary
Effect is more preferable.
Detailed description of the invention

Oil liquid flow graph when Fig. 2 is the oil groove friction plate oil extraction of the prior art；
Fig. 3 is radial velocity distribution map of the oil liquid in oil groove friction panel region；
Fig. 4 is radial velocity distribution map of the oil liquid in sump area；
Fig. 5 is influence variation diagram of the oil film thickness to radial pressure；
Fig. 6 is the structural schematic diagram of the Parabolic oil groove friction plate of the utility model；
Fig. 7 is sectional view of the Parabolic oil groove friction plate of the utility model in the face A-A.
In figure, 1 oil groove, 2 oil groove friction plates.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Attached drawing 6 and attached drawing 7, a kind of Parabolic oil groove friction plate are referred to, the oil groove friction plate 2 is equipped with more
The oil groove 1 of a parabolic shaped structure, and the depth of oil groove 1 is gradually increased from interior radial outer diameter.
The rectangular cross-section structure of the oil groove 1, it may be assumed that oil groove friction plate 2 is cut and is straightened from thickness direction, oil groove
1 forms laciniation with oil groove friction plate 2.
The oil groove friction plate can apply in the double clutch gearboxes of wet type, allow the double clutch gearboxes of wet type faster
Oil extraction, for friction pair can play better cooling effect.
Parabolic oil groove 1 with difference in height meets the type of flow of the centrifugation of oil liquid, can also form Differential pressure flow,
Therefore, compared to traditional radial oil groove, Parabolic oil groove 1 can play the role of more rapidly oil extraction.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the protection scope of the utility model,
Therefore, any modification, equivalent substitution, improvement and etc. made within the spirit and principle of the present invention, should be included in
Within the protection scope of the utility model.
