Embodiment
Being described in below is only exemplary in essence and is not intended to the restriction 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 with by described two part fits together.Inner piece has the spline of the outward edge layout around it, and this spline is configured to match with the complementary splines on the inward flange being arranged in exterior part.Exterior part has the Internal locking groove formed by the spline tooth of exterior part.The spline tooth of exterior part is not present in Internal locking groove.Therefore, when inner piece is positioned in circumferential groove, the spline tooth of exterior part does not stop inner piece relative to the rotation of exterior part.Therefore, when inner piece is positioned in circumferential groove, then inner piece can rotate the convex spline tooth of inner piece and the convex spline tooth of exterior part are aligned.When the convex spline tooth of inner piece is aligned to the convex spline tooth of overlapping exterior part, the convex spline tooth of exterior part stops inner piece moving axially relative to exterior part.The extension part of pin plate or stop pin can be inserted in groove each in parts and move with blocking member rotation relative to each other.
With reference to figure 1A-1B, show exemplary rotary type in an exploded view and keep assembly and it represents by 10 substantially.Rotary type keeps assembly 10 to comprise a pair transmission components, and it is the center support and the backboard 14 that are connected to transmission case (being referred to 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 contrary internal surface 19.Multiple convex spline tooth 16 is around the circumference of the outer surface 18 of backboard 14.Each convex spline tooth 16 has the edge 20 of the groove 22 limited between convex 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 being configured to the band spline matched with the outer surface 18 of backboard 14.Therefore, the internal surface 24 of transmission case parts 12 has the multiple convex spline tooth 26 of the inner circumference layout around it.The convex spline tooth 26 of transmission case parts have limit each in convex spline tooth 26 between the edge 28 of groove 30.Like this, the convex spline tooth 16 of backboard 14 can slide in the groove 30 of transmission case parts 12, and simultaneously, the convex spline tooth 26 of transmission case parts 12 slides in the groove 22 of backboard 14.
Peripheral annular groove 32 is machined or is otherwise formed the convex spline tooth 26 by transmission case parts 12.Circumferential groove 32 extends through the convex spline tooth 26 of transmission case parts 12 around the inner circumference of transmission case parts 12.Circumferential groove 32 enough wide to be assemblied in circumferential groove 32 by backboard 14, backboard 14 can be rotated in circumferential groove 32.Circumferential groove 32 is concordant with the valley of groove 30, in this embodiment, forms the circular groove of the internal surface 24 around transmission case parts 12.In this embodiment, circumferential groove 32 does not have convex spline tooth 26.
As explained above, the spline 16,22 of backboard 14 matches with the spline 26,30 of transmission case parts 12.Like this, backboard 14 can slide along the spline 26,30 of transmission case parts 12 on the axial direction of the central axis X along transmission case parts 12.When the spline 16,22 of backboard 14 matches with the spline 26,30 of transmission case parts 12, spline 16,22,26,30 stops backboard 14 to rotate around central axis X relative to transmission case parts 12.But if backboard 14 slides in the circumferential groove 32 of transmission case parts 12, then convex spline 26 no longer stops backboard 14 to rotate around central axis X relative to transmission case parts 12.This is because transmission case parts 12 do not have convex spline tooth 26 in circumferential groove 32.
When backboard 14 is positioned in circumferential groove 32, annular pin plate 34 is inserted in transmission case parts 12 to stop backboard 14 to rotate around central axis X relative to transmission case parts 12.Pin plate 34 has multiple extension parts 36 that can be inserted in the groove 30 of transmission case parts 12 and the groove 22 of backboard 14.Like this, the extension part 36 of pin plate 34 pins the rotation of backboard 14 relative to transmission case parts 12.
Extension part 36 can be post, pin or leg, as in figure ia.Extension part 36 can have other suitable structure any that can to operate to be assemblied in groove 22,30 thus to stop the rotation between backboard 14 and transmission case parts 12.Pin plate 34 is shown to have ring-shaped, but also can use other shape, such as circular non-hollow shape or with the wheel hub of spoke reaching extension part 36, as an example.In some embodiments, pin plate 34 can be clutch reaction plate or application ring.Pin plate 34 can have the extension part 36 of any suitable quantity, such as 1-40, or one, two, nine or 23 extension parts, as an example.
Eachly in transmission case parts 12, backboard 14 and pin plate can be formed by steel or other suitable material any.
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, the spline 16,22 of backboard 14 is illustrated as matching with the spline 26,30 of transmission case parts 12.Backboard 14 slides along the spline 26,30 of transmission case parts with the assembling starting these two parts.Therefore, the convex spline tooth 16 of backboard 14 is inserted in the groove 30 of transmission case parts 12, and the convex 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 (in shown view along the central axis X of transmission case parts 12, slide into paper neutralization to skid off from paper), but backboard 14 and transmission case parts 12 can not relative to each other rotate, because the structure matched of spline 16,22,26,30 stops them relative to each other to rotate.Backboard 14 slides along the spline 26,30 of transmission case parts 12 and slides into (invisible in fig. 2) in circumferential groove 32.
With reference to figure 2B, once backboard 14 is positioned axially between in the circumferential groove 32 of transmission case parts 12, the convex spline tooth 26 of transmission case parts 12 no longer stops backboard 14 relative to the rotation of transmission case parts 12.When backboard 14 is positioned in circumferential groove 32, because the convex spline tooth 26 of transmission case parts 12 is not present in circumferential groove 32, the rotation between backboard 14 and transmission case parts 12 is possible.Therefore, when it is positioned in circumferential groove 32, backboard 14 can rotate relative to transmission case parts 12.
In fig. 2b, backboard 14 rotates and the convex spline tooth 16 of backboard 14 is aligned with overlapping with the convex spline tooth 16 of transmission case parts 12 in circumferential groove 32.Meanwhile, the groove of backboard 14 22 overlaps mutually with the groove 30 of transmission case parts 12, formed along transmission case parts 12 length, the open space of central axis X in the space that is parallel to groove 22,30.Because the convex spline tooth 26 of clutch housing is positioned on the convex spline tooth 16 of backboard, so backboard 14 can not slide axially along the central axis X of transmission case parts 12 when backboard 14 rotates, as in fig. 2b.Therefore, the convex spline tooth 26 of transmission case parts 12 stops backboard 14 to move axially relative to transmission case parts 12.In other words, the convex spline tooth 26 of transmission case parts 12 pins backboard 14 moving axially relative to transmission case parts 12, and does not need snap ring axially to keep backboard thus stop it to slide along central axis X.Therefore, snap ring can be omitted.
With reference now to Fig. 2 C, then pin plate 24 is installed in transmission case parts 12.Extension part 36 is slid in the groove 30,22 of transmission case parts 12 and backboard 14 to stop backboard 14 to rotate relative to transmission case parts 12.The edge 38 of each extension part 36 abuts against on the edge 20,28 of the convex spline 16,26 of backboard 14 and transmission case parts 12, therefore stops the rotation between transmission case parts 12 and backboard 14 to be moved.In other words, when backboard is rotated such that the convex spline tooth 16 of backboard 14 overlaps mutually with the convex spline tooth 26 of transmission case parts 12, extension part 36 is inserted in the opening between backboard 14 and transmission case parts 12.
With reference to figure 3, side cross section after assembling there is shown rotary type and keeps assembly 10.Backboard 14 and pin plate 34 are installed in transmission case parts 12.The extension part 36 of pin plate 34 stops backboard 14 to rotate relative to transmission case parts 12.The convex 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 the convex spline tooth 26 of transmission case parts 12, and extension part 36 stops 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 the first side 44 of contiguous backboard 14.Second group of staggered clutch plate 46,48 is arranged to the second side 50 of contiguous backboard 14.Therefore, backboard 14 is taken on and can be applied by surface thereon for two different clutch pack.In other words, first group of staggered clutch plate 42,44 is employed to lean against on the first side 44 of backboard 14, and second group of staggered clutch plate 46,48 is employed to lean against on the second side 50 of backboard 14.Therefore, two groups of clutch plates use single backboard 14.Do not use snap ring in this embodiment.
Here accompanying drawing shows a distortion of the present invention.In other embodiments, other transmission components has rotary type as described herein maintenance assembly.Such as, clutch hub can be fixed to transmission case parts 12 in a similar fashion.Especially, another of transmission case parts 12 is organized convex spline tooth and is had the circumferential groove formed through it, and clutch hub can be rotated by " rotations " or part in described circumferential groove be aimed at overlapping to stop clutch hub to move axially relative to transmission case parts 12 with the convex spline tooth of the convex spline tooth with transmission case parts 12 that make clutch hub.Another pin plate 34 or other pin can be used for clutch hub and transmission case parts 12 to lock together rotationally, such as, as described by transmission case parts 12 and backboard 14.
In other mode of execution other, as described herein rotation is utilized to keep two transmission components of characteristic sum method can comprise piston shell and transmission case, center support and transmission case, or expected to stop moving axially between them by spline joint other two parts any together.
In another form, with reference to figure 4, the disclosure comprises the method 100 of the transmission components for the transmission components of band spline being remained to another band spline.The method comprises along the inner piece of the complementary band spline that slides over each other and the exterior part of band spline until inner piece arrives the step 102 of the circumferential groove be formed in exterior part.The method 100 comprises the step 104 be positioned at by inner piece in circumferential groove.The method 100 is also included, and circumferential groove is interior to be rotated or rotates inner piece and make the step 106 that the spline tooth of inner piece and the spline tooth of exterior part align.Spline tooth should be aligned and make the spline tooth of the spline tooth of inner piece in the axial direction along central axis and exterior part overlapping.The method 100 can comprise in the groove being inserted into by stop pin and being formed by the edge of internal tooth and external tooth to stop the step 108 of inner piece and exterior part relative to each other movement in sense of rotation.
