Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the noun of locality of use is as consistent with reference to direction shown in accompanying drawing in " left and right "; " inside and outside " refers to profile inside and outside relative to each parts itself; And wherein, the axis of internal tooth hub 2 and the axis co-axial of external tooth hub 5, and with the axis co-axial of clutch.
The utility model provides a kind of clutch, this clutch comprises internal tooth hub 2, and described internal tooth hub 2 coaxial line the external tooth hub 5 that can rotate relative to described internal tooth hub 2 and along the axis of described internal tooth hub 2 alternating with each other be arranged on friction plate 4 between described internal tooth hub 2 and described external tooth hub 5 and the first antithesis sheet 3, described friction plate 4 is connected to described internal tooth hub 2, described first antithesis sheet 3 is connected to described external tooth hub 5, wherein, described friction plate 4 is set to tilt towards same direction relative to the plane of the axis perpendicular to described internal tooth hub 2 with described first antithesis sheet 3.
The utility model provides a kind of clutch, in this clutch, friction plate 4 and the first antithesis sheet 3 are set to tilt towards same direction relative to the plane of the axis perpendicular to internal tooth hub 2, like this, the existing clutch of the axis perpendicular to internal tooth hub 2 is set to compared to friction plate 4 and the first antithesis sheet 3, in the clutch of the present utility model of equal outer diameter size, the area of contact of friction plate 4 and the first antithesis sheet 3 increases, when the pressure that the piston 6 being subject to equal sizes gives, in clutch of the present utility model, frictional force between friction plate 4 and the first antithesis sheet 3 is larger, thus the working efficiency of clutch is also just higher.
Further particularly, wherein, described friction plate 4 is set to move along the axial of described internal tooth hub 2 relative to described internal tooth hub 2, and described first antithesis sheet 3 is set to move along the axial of described external tooth hub 5 relative to described external tooth hub 5.
When clutch is in separated state, may there is gap between friction plate 4 and the first antithesis sheet 3, after being subject to the pressure that piston 6 gives, friction plate 4 and the first antithesis sheet 3 are along the axial motion of clutch, until be pressed against each other, thus clutch is made to be in bonding state.
Art technology is understandable that, first antithesis sheet 3 can adopt any applicable mode well known in the art with the Placement of external tooth hub 5 and the Placement of friction plate 4 and internal tooth hub 2, such as, in present embodiment, described external tooth hub 5 and described first antithesis sheet 3 are by spline joint, and described internal tooth hub 2 and described friction plate 4 also pass through spline joint.
Wherein, between described friction plate 4 and described external tooth hub 5, there is gap, and there is gap between described first antithesis sheet 3 and internal tooth hub 2.
In addition, see Fig. 2, along the axis of described internal tooth hub 2, be provided with described first antithesis sheet 3 in the both sides of each described friction plate 4.
And, along the axis of described internal tooth hub 2, described clutch has first end (one end being arranged in right side in Fig. 2 is first end) and the second end (one end that Fig. 2 is positioned at left side is first end), in the outside towards described first end of the described first antithesis sheet 3 near described first end, described clutch also comprises and is arranged on the second antithesis sheet 7 between described internal tooth hub 2 and described external tooth hub 5, this the second antithesis sheet 7 (such as, passing through spline) is connected to described internal tooth hub 2; Further, in the outside towards described first end of described second antithesis sheet 7, described clutch also comprises for executing stressed piston 6 to described second antithesis sheet 7; When the second antithesis sheet 7 exists, piston 6 will be applied to the second antithesis sheet 7 between pressure, again indirectly pressure is applied to the first antithesis sheet 3 by the second antithesis sheet 7, therefore, the pressure be delivered on the first antithesis sheet 3 will be more even, effectively reduce between the first antithesis sheet 3 and friction plate 4 and cause local excessive to wear and tear because pressure is uneven.
Further, described second antithesis sheet 7 is parallel to each other with described first antithesis sheet 3.
Piston 6 is connected to oil hydraulic cylinder usually, and apply pressure by oil hydraulic cylinder to described second antithesis sheet 7, after piston 6 applies pressure to the second antithesis sheet 7, the first antithesis sheet 3 that second antithesis sheet 7 promotes next-door neighbour moves along direction from right to left in Fig. 2, and finally make the first antithesis sheet 3, friction plate 4 and the second antithesis sheet 7 are all pressed together, under the drive of the internal tooth hub 2 rotated relative to external tooth hub 5, friction plate 4 rotate relative to the first antithesis sheet 3 and with the first antithesis sheet 3 phase mutual friction, the frictional force produced between them finally causes internal tooth hub 2 and friction plate 4 and external tooth hub 5 and the first antithesis sheet 3 geo-stationary, thus the frictional force between the first antithesis sheet 3 and friction plate 4 is larger, then internal tooth hub 2 and friction plate 4 and external tooth hub 5 and the time needed for the first antithesis sheet 3 geo-stationary shorter, the working efficiency of clutch is higher, and between the first antithesis sheet 3 and friction plate 4, pressure is constant, namely when the ambient pressure that provides of oil hydraulic cylinder is constant, first antithesis sheet 3 is larger with the area of contact of friction plate 4, frictional force then between the first antithesis sheet 3 and friction plate 4 is larger.
Further, see Fig. 2, in present embodiment, along the radially outer direction of described clutch, described friction plate 4 and described first antithesis sheet 3 are set to tilt towards the direction of described second end relative to the plane of the axis perpendicular to described internal tooth hub 2.Wherein, particularly, described friction plate 4 and described first antithesis sheet 3 are 3 ° ~ 8 ° with the angle perpendicular to the plane of the axis of described internal tooth hub 2, large as far as possible to ensure the frictional force between friction plate 4 and the first antithesis sheet 3, and ensure that after friction plate 4 and the pressure between the first antithesis sheet 3 are cancelled, they can be separated each other smoothly simultaneously, avoid produce power to lose and excessive wear.
The utility model additionally provides a kind of automatic transmission case, and this automatic transmission case comprises described clutch; And this automatic transmission case comprises housing and sun gear 1, described external tooth hub 5 is connected to described housing, and described internal tooth hub 2 is connected to described sun gear 1.
