Definitions
- the invention relates to connection arrangements on an articulated shaft, namely between an outer joint part of a constant velocity joint of the universal shaft and a wheel hub, or between an outer joint part of a constant velocity joint of the universal shaft and a shaft flange, e.g. of a shaft journal of a differential gear, for use in the drive train of a motor vehicle.
- a claw coupling between two rotating hollow shafts is known from US 967395.
- the individual claws have internal grooves which, when plugged together, form a circumferential groove in which a snap ring sits inside.
- This type of coupling is not suitable for connecting ring parts to partitions or internals, since access options for installing the snap ring must be obtained through the interior of the hollow shafts.
- a coupling for rigidly connecting coaxial components in propeller shafts is known.
- the components to be connected are each designed with spur gears that are inserted into one another.
- the components to be connected each have a recessed shaft shoulder behind the spur toothing.
- U-profile pieces in the form of circular segments are inserted over the circumference of these shaft shoulders. So that the U-profile pieces do not come loose, they must form a ring assembled or secured by a slid ring or braced against each other with wedges. This leads to a considerable effort in the assembly.
- a locking ring is placed between the ring collars composed of the pawls, which sits on the conical bevel surfaces.
- the flat end faces must be machined precisely in order to form a backlash-free torque-transmitting connection.
- the invention has for its object to provide connecting arrangements between an outer joint part of a constant velocity joint of a drive shaft and a wheel hub or between an outer joint part of a constant velocity joint of a drive shaft and a shaft flange, e.g. to create a differential gear shaft journal that is light and strong, easy to manufacture and quick to assemble.
- a spur toothing of an outer joint part on the wheel hub side of a constant velocity joint of a joint Steering shaft and a spline of a wheel hub are axially inserted into one another and engage in the circumferential direction without play and that the teeth of the spur gears each have radially outwardly open circumferential grooves delimited by two flanks, which together form an annular groove running in the circumferential direction, in which a securing ring is seated on the outside; or in that a Sti toothing of a shaft flange-side joint outer part of a constant velocity joint of a cardan shaft and a Sti toothing of a shaft flange are axially inserted into one another and engage in the circumferential direction without play and that the teeth of the spur gears each have radially outwardly open circumferential grooves delimited by two flanks, which are in common with each other form an annular groove running in the circumferential direction, in which a snap ring is seated on the outside.
- connection arrangements according to the invention have the advantage that they can be installed very quickly and without great effort. Due to the very small displacement distances when inserting the spur gears into one another, cardan shafts can be very easily assembled and disassembled between the wheel hub and shaft flange of a differential gear, especially on the complete vehicle with the wheel suspension fully assembled. This is cheap both for the initial assembly and for repairs.
- the connection arrangement is further characterized by a small number of required components and by a low weight.
- the spur gears can largely be produced by non-cutting reshaping, with only the circumferential grooves having to be machined, either on each of the parts individually or, in the case of intermeshing splines, on both parts simultaneously.
- Torques that are to be transmitted by the cardan shaft are absorbed by the interlocking spur gears of the connection arrangement; Circumferential bending moments on the connection arrangement, the flexed constant velocity joint originate, act primarily on the locking ring seated in the ring groove.
- One flank is loaded by the circlip in each circumferential groove and the other flank is relieved; on circumferential grooves immediately following one another in the circumferential direction, each belonging to a different tooth and thus to another of the two spur gears, the locking ring loads flanks pointing in opposite directions.
- a first favorable embodiment provides that the teeth of the two spur gears, viewed in cylindrical sections, have flanks oriented parallel to the longitudinal axis of the parts, as a result of which they are distinguished by a simple geometry and thus by simple manufacture.
- the circlip and circumferential grooves are to be designed so that the former is supported with both flanks without play in the latter in order to absorb axial forces in both directions without axial displacements when the load direction changes.
- teeth of the two spur teeth viewed in cylindrical sections, have flanks enclosing an angle with the longitudinal axis of the parts, the angles between the flanks of the teeth of the two spur teeth being open in opposite directions and of equal size.
- the teeth of the two spur gears thus have a wedge shape and can be inserted into one another without play.
- the wide tooth feet ensure increased strength and an even load on the teeth.
- a favorable further development has circumferential grooves of the two spur gears, which have mutually parallel flanks, the securing ring having corresponding flanks which are parallel to one another.
- the circumferential grooves are easy to manufacture and standardized standard circlips can be used.
- flanks of the circumferential grooves of the two spur gears enclose an angle with respect to an imaginary axis-normal radial plane, which is open radially outwards, and that the retaining ring has corresponding flanks that enclose the same angle with respect to an imaginary axis-normal radial plane.
- the circumferential grooves thus form an annular groove which receives a retaining ring with a wedge-shaped profile. The radial clamping force of the retaining ring pushes it into the ring groove, whereby axial force components occur due to the wedge shape of the retaining ring.
- a wedge shape of the retaining ring and circumferential grooves which form a reciprocating ring groove, can generate axial force components which ultimately push the two spur gears further into one another. This avoids axial play as well as circumferential play in the connection arrangement.

- the cardan shaft 10 comprises a tripod joint 12 on the differential gear side and a ball constant-velocity fixed joint 13 on the wheel hub side, which are connected to one another via the shaft 11.
- a bellows 14 seals the tripod joint 12 against the shaft 11, a bellows 15 seals the constant velocity ball joint 13 against the shaft 11.
- the tripod joint 12 essentially comprises an inner joint part 17, roller elements 18 and an outer joint part 19; only the outer joint part 19 is of further importance in connection with a connection arrangement according to the invention, which is denoted by Y.
- connection arrangement establishes the connection between the outer joint part 19 and the shaft journal 20 of the differential gear, which is mounted in a roller bearing 21 in the differential gear, the contour of which is only indicated by dashed lines.
- the constant velocity fixed joint 13 essentially consists of an inner joint part 22, torque-transmitting apply 23, a ball cage 24 and an outer joint part 25, the latter only being of importance in connection with the connection arrangement according to the invention, which is designated by X as a detail.
- the outer joint part 25 is connected via the connection arrangement directly to an annular body 26 which is positively fixed on the wheel hub 30 and can be regarded as part of the same.
- a brake disc 27 is screwed onto the wheel hub 30, the wheel hub 30 is mounted in a wheel carrier 29 by means of a double-row ball bearing 28.
- FIG. 3 shows the detail designated as X in FIGS. 1 and 2 on an enlarged scale.
- the wheel hub 30 is provided with a sleeve-shaped projection 31 on which an external toothing 32 is formed before the bearing assembly. Behind this is a cylindrical centering surface 33 which is delimited by a radial stop surface 34.
- the annular body 26, which forms a bearing groove 35, has on the inside a support surface 36, an internal toothing 37 which engages with the external toothing 32, a seat 38 which rests on the centering surface 33, and an end face 39 which contacts the stop surface 34 is present. After pushing the ring body 26 onto the hub 30, the extension 31 is widened so that it rests as a collar 40 against the support surface 36.
- intermeshing end teeth 45, 46 are formed on the outer joint part 25 and on the ring body 26, the teeth of which areas open outwards with respect to a normal radial plane on the longitudinal axis.
- the toothings 45, 46 each apply axially to the ring-shaped outer joint part 25 or to the ring body 26.
- circumferential grooves 47, 48 are formed, which, as will be shown later, complement one another to form an essentially closed annular groove in which a securing ring 50 is seated.
- the lateral flanks 51, 52 of the locking ring 50 are parallel to one another and lie in normal planes with respect to the longitudinal axis of the parts to be connected.
- the flanks of the circumferential grooves 47, 48 which are not designated in any more detail, are aligned accordingly, thus forming rectangular grooves.
- the toothings 45, 46 are designed such that they can be axially displaced relative to one another in the circumferential direction when the tooth flanks bear against play, the locking ring 50 must engage in both circumferential grooves 47, 48 essentially without play, i.e. only an assembly play of the order of approx. 1/10 mm is permitted.
- FIG. 5 shows the detail designated as Y in FIGS. 1 and 4 on an enlarged scale
- FIG. 6 shows a modification of this detail.
- a spline 59 is formed on the shaft journal 20, a spline 60.
- Each outside of the spur gears is executed in the circumferential grooves 61, 62 (FIG. 5) and 63, 64 (FIG. 6), which have the same width but are axial are offset from one another.
- a locking ring 66 (FIG. 5), 68 (FIG. 6) is seated in the circumferential grooves.
- the locking ring 66 has flanks 69, 70 which are parallel to one another.
- the retaining ring 68 has an angle which forms flanks 71, 72 which open outwards.
- the respective flanks of the circumferential grooves 61, 62, 63, 64 correspond in their alignment to the flanks of the retaining ring 66, 68.
- the circumferential grooves 61, 62, 63, 64 are axially offset from one another by a small amount and thus form a jumping annular groove.
- it can be assumed that the toothings 59, 60 are axially supported against one another in the circumferential direction when there is no play.
- a retaining ring 66, 68 inserted in this position then press-fit with the flank 70, 72 on the right flank of the circumferential groove 61, 63 of the spur toothing 59 and with the flank 69, 71 exclusively on the left flank of the circumferential groove 62, 64 of the spur toothing 60.
- a game is permitted that is greater than an assembly game.
- the rectangular ring according to FIG. 5 should be installed while the spur gears are held under pressure.
- the wedge ring according to FIG. 6 can be used without such a compressive pretension between the spur gears, but with a radial pretension of the locking ring 68 itself. A radial retraction of the ring in the circumferential grooves then generates the corresponding axial pressure preload between the spur gears.
- FIGS. 1 to 3 An arrangement with a constant velocity fixed joint 13 'and a wheel hub 30' is shown, which essentially corresponds to the embodiment according to FIGS. 1 to 3.
- an annular body 26 ' is designed separately from a bearing ring 44'.
- the wheel hub 30 ' has an external toothing 32 which cooperates with an internal toothing 37 of the ring body 26'.
- the ring body 26 ' is held by a collar 40 of the wheel hub.
- the end toothing 46 'of the ring body 26' is not designed as an axial extension of a solid ring part, but is essentially formed on the outer circumference of the solid ring part, wherein it is completely supported radially by the latter and does not project axially beyond it.
- the end teeth 45 'of the modified outer joint part 25' thus overlap the area of the solid ring part of the ring body 26 '.
- the respective front end faces of the toothings 45 ', 46' lie in mutually parallel planes normal to the longitudinal axis of the connection arrangement.
- a locking ring 50 ' is seated in circumferential grooves 47', 48 ', which are designed on the outside of the splines 45', 46 '.
- FIGS. 1 to 3 An arrangement of a constant velocity fixed joint 13 ′′ and a wheel hub 30 ′′ is shown, which essentially corresponds to that from FIGS. 1 to 3.
- the Sti toothing 46 '' is formed on the outer circumference of the ring body 26 '', which is axially supported and applied to a separate bearing ring 44 ''.
- the end toothing 46 ′′ is thus supported radially by the massive ring part of the ring body 26 ′′ and does not protrude axially beyond it.
- the outer joint part 25 ′′ has a spline 45 ′′ which engages over the solid ring part of the ring body 26 ′′.
- a locking ring 56 ′′ is seated in circumferential grooves 53 ′′, 54 ′′, which are designed on the outside of the spur gear teeth 45 ′′, 46 ′′.
- the design of the circumferential grooves 53 ′′, 54 ′′ and the securing ring 56 ′′ with conical end faces 57 ′′, 58 ′′ essentially corresponds to the illustration in FIG Figure 6. In the arrangement shown here it can be assumed that the toothings are axially supported against one another by pressure.
- an outer joint part 25 and a wheel hub 30 as well as a bearing 28 are shown, in which the wheel hub 30 is mounted.
- the spur gears 45, 46 have parallel flanks, the flanks, as indicated in FIG. 12, being formed in radial planes through the longitudinal axis of the connecting parts.
- the end faces of the spur gears 45, 46 are each axially spaced from the other part of the connection.
- the parts to be connected are thus basically axially displaceable against one another in the circumferential direction without interlocking teeth.
- circumferential grooves 47, 48 which are formed on the outside of the spur gears, there is a retaining ring 50, which aligns the circumferential grooves 47, 48 in alignment with one another and axially secures the wheel hub 30 relative to the outer joint part 25.
- the securing ring 50 must sit in the circumferential grooves 47, 48, with as little play as possible, which thereby form a closed annular groove.
- the circumferential grooves 47, 48, and the retaining ring 50 can have parallel flanks, the retaining ring 50 then being inserted into the annular groove with a slight assembly play of approximately 1/10 mm.
- the circumferential grooves 47, 48 and the locking ring 50 can also have conical flanks that open outwards, the locking ring 50 being supposed to have radial prestress. To this way, the securing ring 50, the circumferential grooves 47 ,, 48, can be aligned and, when reaching an abutment on both flanks of the circumferential grooves 47 ,, 48, ensure an axial play-free connection between the wheel hub 30 and the outer joint part 25.
- the spur gears 45 2 , 46 2 have flanks which run in a wedge shape in view or in cylindrical sections, the flanks, as indicated in FIG. 14, being formed in radial planes through the longitudinal axis of the connecting parts.
- the end faces of the spur gears 45 2 , 46 2 are each axially spaced from the other part of the connection when the flanks of the spur gears are in mutual contact. The parts to be connected are thus axially supported against one another with play-free interlocking gears.
- circumferential grooves 47 2 , 48 2 there is a locking ring 50 2 , which axially secures the wheel hub relative to the outer joint part against one another.
- the circumferential grooves 47 2 , 48 2 can be axially offset from one another by a small amount, the retaining ring 50 2 only resting on one flank under pressure prestress.
- the circumferential grooves and the locking ring can have parallel flanks.
- the circumferential grooves and the locking ring can also have conical flanks that open outwards, the locking ring should have radial prestress. In this way, the securing ring can ensure a backlash-free connection between the spur gears 47 2 , 48 2 when it comes to rest on one flank of the circumferential grooves.
