Summary of the invention
Task of the present invention is to provide the radial support portion of the described type of a kind of preface, and it is simple in structure and allow axle drive shaft to be installed on the change speed gear box quick and up to specificationly.
According to the present invention, this task that is proposed will solve according to the feature of claim 1.Dependent claims has illustrated favourable improvement embodiment.Task of the present invention will so solve, be provided with the installation assisted parts, described installation assisted parts has first backstop that contrary installation direction plays a role, the axle drive shaft that described installation assisted parts is intended in described that as prescribed ground in the bearing is admitted and calibration need be installed by radial bearing.
Radial bearing can be supported on first backstop, and contrary installation direction acts on the restoring force of radial bearing and can therefore be absorbed because the internal pressure in the change speed gear box raises, thus radial bearing can remain in riding position up to specification in the bearing.Therefore can avoid by this backstop, axle drive shaft driving in the leak free change speed gear box hole that spindle nose inserts change speed gear box with it and for transfer torque with after change speed gear box is connected, and at axle drive shaft by being preferably two part bearing fixed to one another and then by to the fixing of bearing radially and before being fixed in the axial direction, this axle drive shaft moves and cause assembly error because of the contrary installation direction of elevated pressure in the gear box casing.Therefore it is uncomplicated utilizing this installation assisted parts with first backstop that contrary installation direction works, and installation process is safe, need not to interrupt in installation process to be installed in axle drive shaft in the radial support portion correctly to locate in other words by radial bearing up to specificationly.
According to optimal way, interior bearing has two part bearings, wherein first is seated against the installation site and is fixed on described housing or the support, second portion is seated against the split surface place and is fixed on the described first bearing, and these two parts are seated against vertically and the split surface place of radially extension is close to each other.In order to form first backstop, first side away from change speed gear box in the installation site of bearing had first salient in first was seated against.Limit described bearing in installation direction in side direction for reverse, described first salient extend past first at least is seated against the regional area that makes progress in week; And described first salient extends radially inwardly at least in the end and comprises a bit of of at least one length component.This first's bearing can be therewith relatively and in the zone of first salient, have a cross-sectional plane that contains recess.
Therefore, this bearing can constitute by contrary installation direction in the zone line between first salient and the split surface unlimitedly.This has simplified installation, reason is, axle drive shaft inserts along installation direction with its end that drives spindle nose in the change speed gear box hole of defined (preferably inserting change speed gear box under the effect of not bringing into play the moment of torsion transmission), and axle drive shaft is on the swaying direction perpendicular to split surface, be swung away from first's bearing with very little angle or angle branch, and angle that this is very little or angle branch are enough to make the outer ring of radial bearing to be moved on first salient.Can make the outer ring be rocked to its riding position up to specification by the backswing of axle drive shaft thus, the contrary installation direction backstop in outer ring this moment be on this salient.Can so realize this zone line at the method process aspect, promptly, first salient is arranged on first's bearing at first entirely in week longways, so that for example preferably remove fully in the position that zone line will be set subsequently, opens wide so that be seated against contrary installation direction herein.
First's bearing can have guide portion, especially enters riding position up to specification in its outer ring in order to the guiding radial bearing, can have sliding surface and/or have the guiding groove of sliding surface in this this guide portion.Thus, first backstop in other words first salient can form the guiding sliding surface and/or be used at least one limited section with the guiding groove of sliding surface.First salient can have along inclined-plane that installation direction rises as sliding surface away from bearing one side at it.According to optimal way, be respectively equipped with at least one dip plane in backstop and/or on the outer ring, the outer ring of relative motion and first backstop are slided on described at least one dip plane.It is used for sliding along installation direction m guiding sphere shape outer ring Ra as sliding surface and as the dip plane.All can simplify installation by in these measures each, reason has been to realize thus the relative motion of radial bearing/radial support portion, thereby the swing of axle drive shaft is limited in minimum level.Outer ring and first backstop sliding guidance each other make that also the mechanical load that is occurred is minimized.
Have first salient on radially inner side surface and also formed guiding groove, axle drive shaft vertically can be pushed in this guiding groove along installation direction during installation at the zone line that does not have first salient that makes progress both sides next-door neighbours week and extend to split surface always.In advancing, radial bearing relatively bearing with its outer ring side impaction first salient outside.Then, the wobble drive axle correspondingly in order to overcome first salient, and the axle drive shaft that further is along the longitudinal movement.
According to optimal way, in the regional area that first salient extends vertically,, perhaps keep interval perpendicular to this split surface with split surface at the interval that both sides and split surface keep a central angle.First salient that is arranged on first's bearing can form as symmetrical manner with plane mirror vertical with described split surface relatively and that extend along installation direction.Thereby these these regional ends with first salient can keep same intervals at a distance of split surface.Therefore, first salient in the face of the side surface of split surface and the side surface of zone line can form guiding groove, its vertically on, radial bearing can be in the situation lower slider of the minimum amplitude of oscillation of axle drive shaft to riding position up to specification.
According to optimal way, first salient circumferentially extends about it and so extends radially inwardly, and promptly it radially extends along with the circumferential distance at a distance of split surface becomes big and becomes greatly.The possible sickleshaped of first salient is considered to favourable, reason is, utilize this sickleshaped, the contrary installation direction of the lateral openings of bearing can have circle and then be matched with the interior profile of radial bearing outer ring, and profile (thereby being configured to guiding groove) has been simplified radial bearing moving at the first salient upper edge installation direction in this when axle drive shaft is installed.
First salient preferably can regularly or be fixed again adjustable ground and especially be connected with interior bearing with maintaining part.Can be matched with various radial bearings by regulating.
The second portion bearing can have first salient on first side of interior bearing.This first salient preferably is formed on the second portion bearing along whole girth at this, and extends radially inwardly to less a bit of (this a bit of length component that comprises at least) in the end.This first salient first salient preferred in the axial direction and first's bearing is on the sustained height.Fixed to one another and outer ring is close under the situation on this first salient in these two part bearings, and it can guarantee the radial bearing not movability in the axial direction in the radial support portion.According to optimal way, the second portion bearing is constructed to sphere shape part.
Except its above-mentioned backstop function and guiding function, first and/or the second portion bearing on first salient can play simultaneously effect as the indicating device of the riding position up to specification of radial bearing, it clearlys show that axle drive shaft does not move through first salient as yet far enough on installation direction.In addition, the radial bearing outer ring can be positioned under the situation that error is laid on the height of this salient in the axial direction, so that the second portion bearing is not close to first's bearing at the split surface place, and these two part bearings can not be at the split surface place each other as prescribed be close to fixing.
According to advantageous manner, interior bearing has the sphere of basic spill, is used to install the outer ring that is spirogyrate or sphere shape, and described outer ring makes described axle drive shaft self correction when axle drive shaft is installed in the radial support portion.Thus, the sphere of this spill forms under the situation of first salient diametrically and contrary installation direction limits this bearing at the same time on side direction.The sphere of interior bearing can limit the part of the inner space of basic sphere shape as this bearing.This inner space can be described to such space usually, and it is inswept around interior bearing longitudinal axis when the rotation of radially spaced segmental arc, that is to say the whole circle corresponding to segmental arc, at the Tangent diameter of this this segmental arc to inwardly and perpendicular to radius.Because the spherical shape of interior bearing and because the sphere shape exterior contour of outer ring, the outside face of this sphere shape can have crooked inclined-plane, by this inclined-plane, radial bearing divides two stages ground to slide under the situation of being close to first salient thereon.At F/s, driving axial is swung outward or is pushed, and is in about first salient up to radial bearing and shows the position, shows the position at this, and this axle drive shaft is outwards shown by amplitude peak ground.It is in the center, outer ring about installation direction under the situation of the symmetroid shape of outer ring.Along with the further slip of the outer ring in the subordinate phase and first salient, the bearing position in this radial bearing slides in the bearing, wherein radial bearing is in riding position up to specification.
At least the part that limits by first's bearing of inner space can according to the different mode of regular sphere moulding, limit on first side of bearing in contrary installation direction ground side direction, open wide in the contrary zone line of installation direction, it has also simplified outer ring moving on first salient.In addition can be as mentioned above, first salient extends to certain central angle along circumferential both sides from split surface respectively always, and/or extends to certain distance apart from this split surface along the direction perpendicular to split surface.For movable this zone line can remove the spherical area that forms first salient in this zone line by removing material according to aforementioned principles.This removal is preferred so to be carried out to degree, so that sphere is removed at this zone line, and is only limited by cylinderical surface at radial outside in the bearing of zone line.

The specific embodiment
Fig. 1 to Fig. 6 illustrates the radial support portion 1 that is used for axle drive shaft A in the vehicle with different views and partial view.In Fig. 1, this has been schematically shown purely the position of axle drive shaft A, this axle drive shaft A by leak free radial bearing R as the part of change speed gear box G, be installed in the radial support portion 1 by outer ring Ra.Installation site herein, axle drive shaft A is set at outgoing side and has transfer torque between the change speed gear box G of diff D and the wheel F to be driven.Axle drive shaft A can utilize the end that is constructed to drive spindle nose Aa, and installation direction m vertically inserts diff D by change speed gear box hole O.Herein, for realize axle drive shaft A from aligning, the outer ring Ra of the R of radial support portion is sphere shape or taper.
Under the conventional mounting mode, axle drive shaft inserts in the diff along installation direction, thereby internal pressure raises in diff, to such an extent as to cause the contrary installation direction of this axle drive shaft from this diff, to be extruded one section because of this internal pressure raises, and occur position error when making in this radial support portion with interior bearing fixedly.As remedial measures, stipulated installation assisted parts 7 at this, this installation assisted parts 7 has first backstop 8 that contrary installation direction m plays a role, and this installation assisted parts 7 is intended to admittance of as prescribed ground and calibration axle drive shaft A (this axle drive shaft A should install by radial bearing R) in interior bearing 4.First's bearing 5 has first salient 10 on first side 9 away from diff D of interior bearing 4, in order to form first backstop 8.Especially referring to Fig. 6, for reverse in installation direction m side direction limit bearing 3, the first salients 10 at least extend past first bearing 5 at the regional area 11a that makes progress in week, this regional area 11a in both sides all with split surface T maintenance interval 11b.In addition, this first salient a bit of at least 12 (these a bit of radical length components that also comprise) that extend internally.First salient 10 is formed on first's bearing 5 in the mode of opposite planar E (its vertical with split surface T and extend along installation direction m) looking-glass symmetry.
Among the embodiment of radial support portion 1 shown in the figure, interior bearing 4 has the sphere 13 of basic spill, be used to install the outer ring Ra of radial bearing R, this outer ring Ra is spirogyrate or sphere shape at this, this concave configuration of this sphere 13 and outer ring Ra and convex configuration its coupling, the self correction (Selbstausrichtung) when helping axle drive shaft A in radial support portion 1, to install.Shown in Fig. 2 to 6, spill sphere 13 forms diametrically and at the same time under the situation of first salient 10 and limits bearing 3 at side direction superinverse installation direction m.Thereby bearing 3 parts that sphere 13 limits are the class annular arrangement
According to the modification of the sphere shape of bearing 3, first salient 10 is extend past and split surface T regional area 11a at interval only.In the zone line 14 between split surface T and regional area 11a, this sphere 13 relative installation direction m on side direction opens wide.Especially referring to Fig. 6, the interior bearing 4 of first's bearing 5 has been shown in this top perspective view, simultaneously also split surface T is shown with birds-eye view, this sphere 13 in zone line 14 is so dwindled on installation direction m, with the end face (this end face is constructed to sliding surface 16) of the sensing inboard of the cylindrical shape part 15 that forms the part girth and first salient 10.Therefore, with regard to zone line 14, bearing 3 relative installation direction m open wide, and all the other side direction of relative first backstop 8 or inner space 4 limit, and open wide by means of sphere 13.In addition, first salient 10 utilizes its end face that is constructed to sliding surface 16 and back to back two cylindrical shape parts 15 to limit and axially goes up narrow guiding groove 17, as the guide portion 18 of axle drive shaft A and radial bearing R.When it is installed, axle drive shaft A can be supported in the guiding groove 17, and move along installation direction m in the axial direction, until radial bearing R with its outer ring Ra installation direction m forwardly backstop on first salient 10.
This part in the installation process of two steps shown in the sectional side elevation of Fig. 2 to Fig. 5 of radial support portion 1, radial bearing R, axle drive shaft A and diff D and the viewgraph of cross-section; Wherein, radial bearing R among Fig. 2 and Fig. 3 and then axle drive shaft A are in swing position (Verschwenkposition).In this swing position, axle drive shaft A is swinging on the swaying direction v perpendicular to split surface T with very little angle under the height of change speed gear box hole O about pivotal axis s.In Fig. 2, in the middle of first salient 10 moves to along the relative outer ring Ra of installation direction, just move to radially the widest part of outer ring Ra.The road of the swing position that moves to outer ring Ra from outside joint, the sliding surface 16 of the outer ring Ra and first salient 10 slides each other closely.Fig. 3 b is illustrated in the very small full swing of the axle drive shaft A of swing position by the radially maximum height h of first salient 10.For example, if to be takeed for be the riding position correct or up to specification of radial bearing R to this swing position when mounted, from the view of Fig. 2 and Fig. 3 a, can find so, because the swing position of axle drive shaft A, and because radial bearing R is reverse to be stretched out from radial support portion 1 vertically in installation direction m, so second portion bearing 6 (not shown herein) can not be installed on first's bearing 5 in the mode that these two part bearings 5,6 are close at split surface T place.These two part bearings 5,6 can't " cooperate ", and can not interfix.Obtaining another thus installs auxiliary.
In Fig. 4 and Fig. 5, radial bearing R has been in the riding position up to specification of this radial bearing R, and wherein the inside face of outer ring Ra is close to first's bearing 5 in the mode of face contact.The outer ring Ra of radial bearing R has broken away from swing position this moment, and moves to riding position up to specification at the reverse sliding surface 16 in the backswing effect lower edge of swaying direction v first salient 10 of axle drive shaft A.This situation is forced to take place, its reason is, the low elasticity tension force that occurs the similar tongue of axle drive shaft A because of axle drive shaft A towards the swing position swing, this elasticity tension forms reverse restoring force in swaying direction v, this restoring force moves to riding position up to specification along with radial bearing R from swing position again, makes radial bearing R be pressed into first's bearing 5 radially outwardly.This has simplified the correct installation of axle drive shaft A.
Unshownedly owing to be blocked among Fig. 1 be, on second portion bearing 6, also be provided with first salient, it extends beyond the periphery of second portion bearing 6, its height is identical with the axial height of first salient 5 of first bearing 10 in the installation site, and extends radially inwardly to less a bit of (this a bit of length component that comprises at least) in the end.This facilitates radial bearing R fixing in radial support portion 1.
Especially shown in Fig. 2,3a, 4,5a and 6, assisted parts 7 is installed also is included in second backstop 20 that plays a role on the installation direction m, be constructed to second salient 19, in order to location in interior bearing 4 and calibration axle drive shaft A, the radial bearing R of this axle drive shaft A is in Fig. 4 and riding position up to specification shown in Figure 5.Second salient is arranged on facing on second side 21 of diff D in the installation site of first's bearing 5 and second portion bearing 6 (illustrating) with only being blocked in Fig. 1, wherein second salient 19 is arranged on a place highly in the axial direction, and extends with constant numerical value diametrically.Second backstop 20 limits axle drive shaft A and drives spindle nose Aa enters diff D through change speed gear box hole O along installation direction depth of penetration with it.The same with first salient 10, this second salient 19 also is made of the spill sphere 13 that limits bearing 3.
Second portion bearing 6 (being not represented for clarity among the figure) is shell type; And when it normally is positioned on first's bearing 5 at split surface T place (Fig. 1), the connecting element 22 (as shown in Figure 6) that split surface T is passed in utilization is fixed on this second portion bearing on first's bearing 5, so that radial bearing R is not clamped in the radial support portion 1 not movablely.
Therefore, utilize the radial support portion 1 can be according to the light radial bearing R that installs of following step simple and reliablely, wherein axle drive shaft A be contained in the radial support portion 1 in the installation site by this radial bearing R:
The mobile axle drive shaft A of guiding in guiding groove 17;
