As mentioned above, in the inside face of hub 16, be used between the outer slot rolling of ball web 20 being set outside.Shown in Fig. 3,5,7,8 and 10, described web has the importing profile 16a that is arranged on outer slot rolling 19 both sides, and being used for outside, hub 16 imports cage 15 vertically.Importing profile 16a extends with the corresponding diameter of the external diameter of cage 15 with approaching at least from the end 2a of drive side, and changing the first cage centering face 16b near after half of the axial length of hub outside at least, described cage centering face is along extending obliquely towards the direction of cage axis III.Here the first cage centering face 16b correspondingly compensates cage 15 spherically and is designed to ball-shaped centering district 26a.
As shown in figure 10, in not having ball and not having under the situation of hub, cage 15 (importing) can be realized by the importing profile 16a that the both sides of slot rolling 19 outside two radially relative each other first are arranged respectively along the direction of arrow X, wherein, make the plane of rotation of cage be in the rectangular position of plane of rotation with outer hub, that is to say that outer hub axis II is perpendicular to one another with cage axis III, contact with the first cage centering face 16b with its centering district 26a until cage 15.After this, as describing in detail among the DE10209933A1, cage can be swung, so that ball and interior hub to be installed.
As shown in Fig. 4,6,7,8 and 10, outer hub or its web shown in be designed in the form of implementation, make that the both sides of slot rolling 19a are provided with other importing profile 16c outside second, thus also can be, promptly import cage 15 along the direction of arrow Y by the end 3a of slave end.For this reason, import profile 16c and also with at least extend towards slave end 3a near diameter corresponding to the external diameter of cage 15, and at least near after half of the axial length of cage, change the second cage centering face 16a on the outer hub, that be used for cage over to.Described importing profile is from tilting towards the direction of cage axis III here.At this moment, identical with the first cage centering face, the second cage centering face 16d correspondingly compensates (angleichen) cage spherically and is designed to ball-shaped centering district 26.
With the jack to jack adapter hachure cage centering face 16b is shown in Fig. 7,8 and 10, in fact described centering face is appreciiable for the viewer in birds-eye view, but is positioned at the side that outer hub deviates from the viewer.Is sightless with the cage centering face 16d shown in single shade line for the viewer, but it is towards the viewer.
Between two areal of supports of cage 15 or centering district 26a, process the circumferential profile that in form of implementation, is designed to evener 26b aptly, the particularly advantageously effect of super fatting agent groove of described circumferential profile by Figure 10.
The importing of cage 15 also can be undertaken by two importing profile 16c that are arranged in the both sides of slot rolling 19a outside radially relative second along the direction of arrow Y, wherein, make the plane of rotation of cage be in respect to 45 ° of location deflections shown in Figure 10, transverse to the position of outer hub plane of rotation, that is to say that outer hub axis II is perpendicular to one another with cage axis III.
The above-mentioned symmetrical structure of outer hub makes can be with particularly advantageous mode as the outer hub of shaping without stock removal spare manufacturing.Thereby molds/tools profile the hub, that form cage spigot surface and the profile of formation importing vertically outside both sides enter can be extracted from outer hub.Because outer hub does not have heavy configuration of cutting, but outer hub chipless ground is made.
Now, for when the larger axial force that acts on another part axle 3 by part axle 2 occurring in the direction of arrow F, avoid the scope inner bending of transmission shaft 1 at movable joint 8, and can enter the passenger inner space revolvably,, taking place in head-on crash or the car accident, movable joint 8 is designed to get loose as special meeting.For this reason, in an illustrated embodiment, shown in Fig. 4 and 9, with movable joint outer shroud just outer hub and/or carry housing secretly and be designed to elastically deformable.If partly big axial force occurring on the axle 2 and 3 now, so that by the distance between these two attaching partss 4 of axial force shortening and 5, movable joint internals or interior hub 10 can move vertically with respect to outer part of movable joint or outer hub 16.At this moment, by the move axially ball 14a that radially omit to external pressure second raceway pair of the second interior ball receway 18a together with the movable joint internals, thereby outer hub is expanded at least partly.At this moment, in position shown in Figure 9, as shown in Figure 3, and the ball 14 in the first raceway pair that radially inwardly gets loose, and the amount that gets loose is greater than the amount that is obtained by the ball 14a that radially outwards moves.At this moment, also can making like this gets loose becomes easily, and promptly outer hub is in position corresponding to Fig. 9 in short time near having polygonal shape at interior hub, and described shape is definite by the relevant position of four ball 14a.Interior hub cross position shown in Figure 9 further axially move into outside during hub, ball 14a radially inwardly jumps out from interior ball receway 18a.Thus, movable joint gets loose, thereby interior hub 10 is together with the further entering part axle 3 vertically of part axle 2.Flexible can unhinderedly carry out of part axle 2 in part axle 3, or especially can be advantageously by in part axle 3, the buffering that an axial buffer device that can be designed to work is determined is set gradually.
The elasticity of outer hub also can be understood as the outer hub of direct encirclement, i.e. the elasticity of affected member when distortion, for example carry the elasticity in the admittance district 17 of housing 9 secretly.Certainly, within the scope of the invention, it is one that outer hub 16 also can be designed to and carry secretly housing 9.
When swivel joint owing to interior hub moves axially when getting loose with respect to outer hub, cage 15 is bearing on the cage centering face 16b towards the spherical centering district (areal of support) of slave end end 3a 26a, thereby cage 15 and the ball 14a that kept by cage also relatively remain on the original position in respect to the position of outer hub 16 at interior hub 10 shown in Figure 9, until when further moving axially, the second ball receway 18a is place kick 14a no longer radially.Suitable is, cage 15 is designed to stable like this, thereby described cage does not bear above-mentioned condition with can being destroyed.
According to the present invention, alternatively or except beyond the above-mentioned elastic dilatation of hub, interior hub 10 also can relate to into elastomeric like this, promptly because the distortion of interior hub relieving ball 14a in the zone of the second ball receway 18a at least makes drive joint get loose thus.This can be achieved like this, promptly for example by in interior hub, process recess from drive side at least in an in-to-in zone that radially is arranged in ball, and/or outside in the hub, radially be arranged in the exterior zone of ball one and process recess in the zone of slave end at least.
