Description
Technical field
The utility model relates to a kind of shifting element friction plate and gearbox shifting elements.
Background technique
At present in automatic gearbox for vehicle, multi-sheet wet-type friction plate shifting element is used for the combination of two transmission parts and divides
From the linking of realization power transmitting is interrupted.In gearbox, friction plate is connect with a rotating element, antithesis piece and another rotation
Turn element connection, under oil pressure effect, piston axially moves, and friction plate and antithesis piece are fitted closely, and utilizes two components
Sliding frictional resistance removes the speed difference of two moving components, but since the locations of structures relationship of snap ring and antithesis piece in practice causes to rub
The outer ring pressure of piece is greater than inner ring pressure, and antithesis piece is unevenly distributed with friction plate interface pressure, is unfavorable for the maximum sliding torsion that rubs
The generation of square, while friction plate outer ring generates more heat in sliding rub, inner ring generation heat is less, and heat distribution is uneven
It is even, cause local temperature excessively high, be easy to cause friction plate or antithesis piece ablation, the functional characteristic for influencing shifting element even causes
Failure of removal influences the service life of shifting element.
Utility model content
The utility model is intended to provide a kind of simple structure, novelty, the shifting element that can extend shifting element service life
Use friction plate.A kind of gearbox shifting element made using the utility model shifting element of friction plate is also provided simultaneously.
It is realized by following scheme:
A kind of shifting element friction plate, including friction chip and two friction facings, the friction chip and friction lining
The cross section of piece is integrally in circular ring shape, and the thickness of the friction facing is gradually increased from outer ring to inner ring and the one side of friction facing
For concordant planar structure, two friction facings are with the outer ring on the concordant two sides and friction facing for affixing to friction chip on one side
With the outer ring flush of friction chip, the friction plate section view generally wedge shaped structure in both ends.
Further, the friction facing outmost turns are with the cumulative thickness difference of innermost circle no more than in corresponding shifting element
Total Separation between antithesis piece and friction plate.
Further, the material of the friction chip is steel disc, and the material of the friction facing is friction material.
A kind of gearbox shifting element, including support arm, inner support, several antithesis pieces and piston, it is described several
The outer ring spline of antithesis piece is connected in support arm, friction plate is provided between two neighboring antithesis piece and friction plate and antithesis piece
Between there are gap, the friction plate is shifting element friction plate as described above, and the inner ring spline of the friction plate connects
On inner support, the inner support empty set in support arm, the piston bush in the support arm and piston towards inner face with
Outmost antithesis piece faces contact towards outer end face.
Further, the support arm towards being equipped with snap ring on inner face, the snap ring towards outer end face and most the inside
Antithesis piece be in contact towards inner face.
The shifting element friction plate of the utility model, structure is simple, novel, uses the gearbox shift member of its production
Part, since integral outer ring's thickness of friction plate is less than inner ring thickness, when friction plate is in conjunction with antithesis piece, friction plate inner ring is larger
Thickness can compensate for the local gap as caused by structure unbalance loading and uneven axial deformation, can improve in shifting element and rub
The cunning of piece and antithesis piece is rubbed characteristic, and the pressure improved between friction plate and antithesis piece is distributed, and makes shape between friction plate and antithesis piece
At pressure distributed areas as uniform as possible, so that the heat of the sliding generation that rubs disperses as far as possible, friction plate and antithesis piece are reduced
Operating temperature avoids friction plate or antithesis piece that ablation occurs, improves the functional reliability of shifting element and prolong its service life.
Detailed description of the invention
Fig. 1 is the diagrammatic cross-section of shifting element friction plate in embodiment 1；
Fig. 2 is the diagrammatic cross-section of gearbox shifting element in embodiment 2.
Specific embodiment
Embodiment simply to illustrate that the utility model a kind of implementation, not as to scope of protection of the utility model
Restricted explanation.
Embodiment 1
A kind of shifting element friction plate 1, as shown in Figure 1, including friction chip 11 and two friction facings 12, rub core
The cross section of piece 11 and friction facing 12 is integrally in circular ring shape, and the thickness of friction facing 12 is gradually increased and rubs from outer ring to inner ring
The one side for wiping liner is concordant planar structure, and 12 outmost turns of friction facing are with the cumulative thickness difference of innermost circle no more than corresponding
Total Separation in shifting element between antithesis piece and friction plate, two friction facings 12 affix to friction with concordant on one side
The outer ring flush of the two sides of chip 11 and the outer ring of friction facing 12 and friction chip 11,1 section view of friction plate generally both ends
Wedge shaped structure.The material of friction chip 11 is steel disc, and the material of friction facing 12 is friction material.
Embodiment 2
A kind of gearbox shifting element, as shown in Fig. 2, (not illustrating interior branch in figure including support arm 2, inner support
Frame), three antithesis pieces 3 and piston 4, the outer ring spline of three antithesis pieces 3 be connected in support arm 2, two neighboring antithesis piece 3 it
Between be provided between friction plate 1 and friction plate 1 and antithesis piece 3 there are gap, friction plate 1 is shift member as described in Example 1
The inner ring spline of part friction plate 1, friction plate 1 is connected on inner support, and in support arm 2, piston 4 is sleeved on inner support empty set
In support arm 2 and piston 4 is contacted towards inner face with outmost facing towards outer end face for antithesis piece 3, and support arm 2 is inwardly
Snap ring 5 is installed, being in contact towards inner face towards outer end face and innermost antithesis piece 3 of snap ring 5 on end face.
When gearbox is not worked with shifting element, friction plate is rotated with the moving component that is connected, antithesis piece and another
Moving component rotation, it is contactless between friction plate and antithesis piece.When gearbox is worked with shifting element, piston is pushed away oil pressure
Under dynamic, the direction Xiang Kahuan is mobile, pushes antithesis piece, friction plate axial movement, after eliminating gap between friction plate and antithesis piece,
Friction plate starts to contact to slide with antithesis piece to rub, and as oil pressure continues to increase, sliding friction makes two relative movement part revolving speeds
It reaches unanimity, when oil pressure reaches maximum, due to the supporting role of snap ring, the displacement of the inner ring of antithesis piece and friction plate is greater than
Outer ring causes outer ring pressure much larger than inner ring, and the outer ring thickness of friction plate is less than inner ring thickness at this time, using the thickness of inner ring
Degree compensates for the partial dislocation amount of inner ring, reduces the maximum pressure of outer ring, avoids that sliding rub is caused to generate greatly since pressure is excessive
Frictional heat is measured, the ablation of antithesis piece or friction plate is caused, after oil pressure revocation, piston is moved to initial in return spring effect
Position, friction plate and antithesis piece separate.
