Embodiment
Below be described in and only be exemplary in essence and be not intended to limit the disclosure, application or use.
The disclosure provides a kind of rotary type to keep assembly, comprises internal speed changer parts and outer transmission components, has spline separately so that described two parts are combined together.Inner piece has the spline of arranging around its outward edge, and this spline is configured to match with complementary splines on the inward flange that is arranged in exterior part.Exterior part has the Internal locking groove by the spline tooth formation of exterior part.The spline tooth of exterior part is not present in the Internal locking groove.Therefore, in the time of in inner piece is positioned in circumferential groove, the spline tooth of exterior part does not stop inner piece with respect to the rotation of exterior part.Therefore, in the time of in inner piece is positioned in circumferential groove, inner piece can rotate then so that the protruding spline tooth of the protruding spline tooth of inner piece and exterior part aligns.When the protruding spline tooth of inner piece was aligned to the protruding spline tooth of overlapping exterior part, the protruding spline tooth of exterior part stoped inner piece moving axially with respect to exterior part.The extension part of pin plate or stop pin can be inserted in the parts in each the groove to stop parts rotation relative to each other to be moved.
With reference to figure 1A-1B, there is shown exemplary rotary type in decomposition and keep assembly and its substantially by 10 expressions.Rotary type keeps assembly 10 to comprise a pair of transmission components, and it is center support and the backboard 14 that is connected to transmission case (being known as transmission case parts 12 here) in this embodiment.
In this embodiment, backboard 14 has the shape of annular substantially, and it has outer surface 18 and opposite internal surface 19.A plurality of protruding spline tooths 16 are around the circumference of the outer surface 18 of backboard 14.Each protruding spline tooth 16 has the edge 20 that limits the groove 22 between the protruding spline tooth 16.
In this embodiment, transmission case parts 12 are around backboard 14 arranged concentric.Transmission case parts 12 have the internal surface 24 that is configured to the wounded in the battle key that matches with the outer surface 18 of backboard 14.Therefore, the internal surface 24 of transmission case parts 12 has a plurality of protruding spline tooth of arranging around its inner circumference 26.The protruding spline tooth 26 of transmission case parts has the edge 28 that limits the groove 30 between each in the protruding spline tooth 26.Like this, the protruding spline tooth 16 of backboard 14 can slide in the groove 30 of transmission case parts 12, and simultaneously, the protruding spline tooth 26 of transmission case parts 12 slides in the groove 22 of backboard 14.
Peripheral annular groove 32 is machined or otherwise forms the protruding spline tooth 26 by transmission case parts 12.Circumferential groove 32 extends through the protruding spline tooth 26 of transmission case parts 12 around the inner circumference of transmission case parts 12.Circumferential groove 32 is enough widely to make backboard 14 to rotate in circumferential groove 32 in the circumferential groove 32 so that backboard 14 is assemblied in.Circumferential groove 32 is concordant with the paddy portion of groove 30, in this embodiment, forms around the circular groove of the internal surface 24 of transmission case parts 12.In this embodiment, circumferential groove 32 does not have protruding spline tooth 26.
Explain that as top the spline 16 of backboard 14,22 matches with the spline 26,30 of transmission case parts 12.Like this, backboard 14 can slide at the spline 26,30 along transmission case parts 12 on the axial direction of the central axis X of transmission case parts 12.When the spline 16,22 of backboard 14 matched with the spline 26,30 of transmission case parts 12, spline 16,22,26,30 stoped backboard 14 to rotate around central axis X with respect to transmission case parts 12.Yet if backboard 14 slides in the circumferential groove 32 of transmission case parts 12, protruding spline 26 no longer stops backboard 14 to rotate around central axis X with respect to transmission case parts 12.This is because transmission case parts 12 do not have protruding spline tooth 26 to exist in circumferential groove 32.
In the time of in backboard 14 is positioned in circumferential groove 32, annular pin plate 34 is inserted in the transmission case parts 12 to stop backboard 14 to rotate around central axis X with respect to transmission case parts 12.Pin plate 34 has a plurality of extension parts 36 in the groove 22 of the groove 30 that can be inserted into transmission case parts 12 and backboard 14.Like this, the extension part 36 of pin plate 34 pins backboard 14 with respect to the rotation of transmission case parts 12.
Each can both be formed by steel or any other suitable material in transmission case parts 12, backboard 14 and the pin plate.
With reference now to Fig. 2 A-2B,, rotary type keeps assembly to be illustrated as partly being assembled, and in Fig. 2 C, it is illustrated as fully being assembled.In Fig. 2 A, the spline 16,22 of backboard 14 is illustrated as matching with the spline 26,30 of transmission case parts 12.Backboard 14 slides to begin the assembling of these two parts along the spline 26,30 of transmission case parts.Therefore, the protruding spline tooth 16 of backboard 14 is inserted in the groove 30 of transmission case parts 12, and the protruding spline tooth 26 of transmission case parts 12 is inserted in the groove 22 of backboard 14.In this stage of assembling, backboard 14 can slide along the central axis X of transmission case parts 12 (shown in view in, sliding into the paper neutralization skids off from paper), but backboard 14 and transmission case parts 12 can not relative to each other rotate, because spline 16,22,26,30 the structure that matches stop them relative to each other to rotate.Backboard 14 slides and slides into (invisible in Fig. 2 A) in the circumferential groove 32 along the spline 26 of transmission case parts 12,30.
With reference to figure 2B, in case backboard 14 axially is positioned in the circumferential groove 32 of transmission case parts 12, the protruding spline tooth 26 of transmission case parts 12 no longer stops backboard 14 with respect to the rotation of transmission case parts 12.In the time of in backboard 14 is positioned in circumferential groove 32, because the protruding spline tooth 26 of transmission case parts 12 is not present in the circumferential groove 32, so the rotation between backboard 14 and the transmission case parts 12 is possible.Therefore, in the time of in it is positioned in circumferential groove 32, backboard 14 can rotate with respect to transmission case parts 12.
In Fig. 2 B, backboard 14 rotates in circumferential groove 32 and makes the protruding spline tooth 16 of backboard 14 and the protruding spline tooth 16 of transmission case parts 12 align with overlapping.Simultaneously, the groove of backboard 14 22 overlaps mutually with the groove 30 of transmission case parts 12, forms along the open space length of transmission case parts 12, that be parallel to the central axis X in groove 22,30 the space.Because the protruding spline tooth 26 of clutch housing is positioned on the protruding spline tooth 16 of backboard, so backboard 14 can not endwisely slip along the central axis X of transmission case parts 12 when backboard 14 rotates, as shown in Fig. 2 B.Therefore, the protruding spline tooth 26 of transmission case parts 12 stops backboard 14 to move axially with respect to transmission case parts 12.In other words, the protruding spline tooth 26 pinning backboards 14 of transmission case parts 12 move axially with respect to transmission case parts 12, thereby and do not need snap ring axially to keep backboard to stop it to slide along central axis X.Therefore, can omit snap ring.
With reference now to Fig. 2 C,, pin plate 24 is installed in the transmission case parts 12 then.Extension part 36 is slid in the groove 30,22 of transmission case parts 12 and backboard 14 to stop backboard 14 to rotate with respect to transmission case parts 12.The edge 38 of each extension part 36 abuts against on the protruding spline 16,26 edge 20,28 of backboard 14 and transmission case parts 12, therefore stops the rotation between transmission case parts 12 and the backboard 14 to be moved.In other words, when backboard is rotated when making the protruding spline tooth 26 of protruding spline tooth 16 and transmission case parts 12 of backboard 14 overlap mutually, extension part 36 is inserted in the opening between backboard 14 and the transmission case parts 12.
With reference to figure 3, the side cross section after assembling there is shown rotary type and keeps assembly 10.Backboard 14 and pin plate 34 are installed in the transmission case parts 12.The extension part 36 of pin plate 34 stops backboard 14 to rotate with respect to transmission case parts 12.The protruding spline tooth 26 of transmission case parts 12 stops backboard to move axially along central axis X.Together, the internal surface 24 of transmission case parts 24 comprises that the protruding spline tooth 26 of transmission case parts 12 and extension part 36 stop backboard movement in any direction; In other words, they retrain backboard 14 in all directions.
First group of staggered clutch plate 40,42 is arranged to first side 44 of contiguous backboard 14.Second group of staggered clutch plate 46,48 is arranged to second side 50 of contiguous backboard 14.Therefore, backboard 14 is taken on for two different clutch pack and can be used surface by thereon.In other words, first group of staggered clutch plate 42,44 is employed on first side 44 that leans against backboard 14, and second group of staggered clutch plate 46,48 is employed on second side 50 that leans against backboard 14.Therefore, two groups of clutch plates use single backboard 14.Do not use snap ring in this embodiment.
The accompanying drawing here shows a distortion of the present invention.In other embodiments, other transmission components has rotary type maintenance assembly as described herein.For example, clutch hub can be fixed to transmission case parts 12 in a similar fashion.Especially, another of transmission case parts 12 organized protruding spline tooth and had the circumferential groove that passes its formation, clutch hub can be in described circumferential groove by " rotations " or partial rotation so that the protruding spline tooth of clutch hub is aimed at the protruding spline tooth of transmission case parts 12 with overlapping moves axially with respect to transmission case parts 12 with the prevention clutch hub.Another pin plate 34 or other pin can be used for clutch hub and transmission case parts 12 are locked together rotationally, for example, and as top described with reference to transmission case parts 12 and backboard 14.
In other other mode of execution, utilize rotation as described herein to keep two transmission components of feature and method can comprise piston shell and transmission case, center support and transmission case are perhaps stoped moving axially between them by any other two parts and the expectation that spline links together.
