Description

Tape reel

Technical Field

The invention relates to a belt reel of a belt retractor for a safety belt, in particular in a safety belt system of a vehicle.

Background

The tape reel can be coupled, if necessary, with a tape tensioner which rotates the tape reel in the take-up direction so that the tape is wound onto the tape reel. For this purpose, the tape spool usually has one or more driving engagement sections which are arranged concentrically to the longitudinal axis of the tape spool and via which the driving force is transmitted from the tape tensioner to the tape spool.

For reasons of manufacturing engineering, such a drive-engaging part is usually not formed integrally with the tape spool, but rather on a separate component, since it is made of a high-strength material, for example, and often also has a complex geometry. In order to fasten the component with the entraining toothing to the reel body of the tape reel, said component has hitherto been pressed onto the shaft of the reel body and additionally secured if necessary.

Disclosure of Invention

The aim of the invention is to simplify the production of the tape spool and thus to reduce the costs.

The object is achieved by a tape reel. According to the invention, the tape reel comprises a reel body for receiving the tape, which reel body has a longitudinal axis, and a component which is arranged concentrically with respect to the longitudinal axis and is fixed to the reel body in a rotationally fixed manner, said component having a carrying engagement. At least one clamping element is provided on the component and on the spool body, respectively, which clamping element is designed as mutually complementary wedge surfaces extending in the circumferential direction. The member is connected to the spool body by means of a clamping connection between the wedge faces, which can be established by rotation of the member relative to the spool body.

The clamping connection of the tape reel according to the invention is neither a bayonet connection nor a screw thread. In contrast to this connection, the clamping element does not require axial clamping surfaces and the clamping effect is achieved exclusively by the surface contact between the wedge surfaces in the circumferential direction. The main holding force between the component and the reel body in the axial direction, i.e. along the longitudinal axis, is the clamping force of the clamping connection generated by friction.

In order to mount the entraining engagement on the tape reel, it is merely necessary to sleeve the component on the reel body and then to rotate the two parts relative to one another in the direction of establishing the clamping connection, wherein the clamping connection is tightened. The clamping connection here preferably forms the only connection between the component and the reel body, so that a further fixing of the component to the reel body, for example by means of a locking or adhesive connection, can generally be dispensed with. After the clamping connection is established, the component is firmly fixed with respect to the longitudinal axis not only with respect to the direction of rotation but also with respect to the axial direction along the longitudinal axis.

Another advantage is that the member can be separated from the spool body again by relatively rotating the spool body and the member in a direction opposite to the direction of establishment. In this way, the different materials of the recovery member and the spool body can be separated without problems or the entraining engagement can be exchanged without problems, for example in the maintenance sector.

The component preferably has a driving engagement for the reversible belt tensioner, by means of which the driving energy is transmitted from the belt tensioner to the belt reel. The entraining engagement can of course also be used, for example, for coupling with a pyrotechnic belt tensioner or other component of a belt retractor.

The force transmission from the belt tensioner to the belt reel is usually only carried out in the winding direction of the strip onto the reel body. It is therefore advantageous to arrange the wedge faces such that the direction of establishment of the clamping connection coincides with this direction of rotation. This causes the clamping connection to tighten further when the belt tensioner is activated. In this way, even very high forces acting during the tensioning process can be absorbed without problems by the clamping connection.

The two wedge faces of the co-acting clamping elements on the component and on the reel body are configured to be complementary to one another, which means that the inclination of the wedge faces in the radial direction, as seen in the circumferential direction, has the same amount for the two wedge faces in contact. When the clamping connection is established, the clamping elements advantageously lie flat against one another over a large part of the circumference, in order to generate a high clamping force by friction.

Preferably, each wedge-face describes a spiral in circumferential direction with respect to the longitudinal axis. The spiral may in particular be a logarithmic spiral. The clamping force achieved can be adjusted in a simple manner by the inclination of the spiral. The wedge-shaped surface extends in the circumferential direction over a maximum of not more than 360 °. If a plurality of clamping elements are provided on the component or on the spool body, all wedge surfaces together extend over a maximum of not more than 360 ° on the component or on the spool body. The different wedge faces do not overlap seen in the axial direction, so that the thread has no axial component, i.e. a form without threads.

The wedge surface extends in particular with a geometry that is constant in the axial direction with respect to the circumferential direction, i.e. along the longitudinal axis, over a clamping region in which the wedge surfaces of the spool body and the component are in surface-like contact in order to generate a sufficient clamping force. The clamping area is for example about 2 to 25mm long.

The invention therefore also provides the possibility of compensating for axial tolerances between the reel body and the component. For this purpose, the component and the reel body are nested into one another and are moved axially relative to one another in the region of the clamping region until their desired relative position is reached before the clamping connection is established.

Preferably, the member or reel body has a recess provided with an inner circumferential wall on which at least one clamping element is provided, and the reel body or member has an outer circumferential wall on which at least one complementary clamping element is provided.

The clamping element and thus the wedge surface are preferably formed integrally with the spool body and the component on the respective (inner or outer) circumferential wall. Each wedge surface of the clamping connection here advantageously forms a radially inner or radially outer surface, depending on whether the wedge surface is arranged on the spool body or on the component. The radial surfaces bear against one another in a planar manner, as a result of which a clamping force is generated.

Preferably, the wedge surfaces of all the clamping elements on the component or on the reel body, respectively, occupy a major part of the circumferential surface of the respective component.

The clamping region, in which the wedge faces lie flat against one another, comprises at least one axial section of the circumferential wall.

In the clamping region, the circumferential surface of the wedge surface on the component or on the reel body preferably forms a cylindrical surface which has a cross section which is constant in the axial direction over the entire clamping region.

In a cross section perpendicular to the longitudinal axis of the respective circumferential wall, the circular envelope in the circumferential direction is in particular concentric with the longitudinal axis.

In a preferred embodiment, only one single clamping element is provided on the component and on the reel body, respectively, which clamping element has a single wedge surface. However, it is also possible to provide a plurality of, in particular two or three, clamping elements, each having a single wedge surface, on the component and on the spool body, which are distributed in the circumferential direction about the longitudinal axis.

In the case of a single clamping element, the wedge surface thereof preferably extends over approximately 360 ° in the circumferential direction. When two clamping elements are used, each wedge-face preferably extends over approximately 180 ° in the circumferential direction, and when three clamping elements are used, each wedge-face accordingly preferably extends over approximately 120 ° in the circumferential direction, so that the entire circumferential length is available for the wedge-faces. It is also conceivable to provide more than three clamping elements. Overall, a more balanced centering and moment distribution can be achieved by increasing the number of wedge-facets, while using a smaller number of wedge-facets allows a lower pitch angle per single wedge-facet and thus a better clamping effect. The exact design of the clamping connection with respect to the length of the wedge faces in the circumferential direction and the number of clamping elements and wedge faces distributed over the circumference are at the discretion of the skilled person.

Since the entraining engagement is usually made of a harder material than the reel body, it is often advantageous to manufacture the entire component from this material, so that the component is made of a harder material than the reel body. In this case, it can be advantageous if the entire component, including the entraining engagement, is produced in one piece. Due to the difference in material hardness, the wedge surface on the component can be partially embedded in the wedge surface on the spool body, thereby improving the form fit. In this case, however, the main holding force of the fastening of the component on the reel body is always achieved by the friction of the wedge faces lying flat against one another, rather than by the formation of axial steps.

In a second function, in addition to the fastening of the entraining mesh on the spool body, this component can be used to fasten a bearing pin, which forms an end-side bearing of the tape spool, on the tape spool for rotating the tape spool about its longitudinal axis.

A first possibility consists in that the bearing pin is arranged on the reel body concentrically to the longitudinal axis, the establishment of the clamping connection reinforcing the fixing of the bearing pin on the reel body. The bearing pin is in this case mounted directly on the spool body.

For example, the bearing pin can first be inserted into the receiving opening on the spool body. When the clamping connection between the component and the reel body is tightened, a force then acts on the edge of the receiving opening, which presses the edge of the receiving opening together with the bearing pin and thus increases the fixing force acting on the bearing pin. In this case, it is also advantageous for the member to be made of a harder material than the spool body, in order to ensure sufficient deformation of the edge of the opening in the spool body. Additional adhesive connections, for example, by microencapsulated adhesives applied beforehand to the bearing pins, can usually be dispensed with.

If necessary, the bearing pin can first be pressed into the receiving opening, wherein a relatively low pressure can be used, which allows the insertion depth of the bearing pin to be specifically determined, for example, in order to compensate for axial tolerances. In this positioning of the bearing pin, the bearing pin is substantially undeformed. Only by tightening the clamping connection with respect to the wedge faces of the rotating spool body and the component is the material of the spool body pressed together in the radial direction around the bearing pin, whereby the fixing force acting on the bearing pin is increased considerably in comparison with the state directly after the pressing-in. Since the clamping connection is established only by radial forces, no axial forces act on the bearing pin along the longitudinal axis, so that the bearing pin no longer moves in the axial direction.

Another possibility consists in providing the component with a bearing pin, in providing the component with the bearing pin concentrically to the longitudinal axis and then in fixing the bearing pin to the reel body by means of a clamping connection of the component to the reel body. The bearing pin is preferably in this case constructed in one piece with the component. By tightening the clamping connection, the bearing pin is also installed at the same time and the clamping connection based on the centering action is automatically centered correctly on the longitudinal axis.

The precise axial positioning of the bearing pin can be achieved by adjusting the axial position of the component relative to the spool body before the clamped connection is tightened, in that: by slightly displacing the wedge faces in the clamping region in the axial direction relative to one another until the desired axial position of the bearing pin is reached. Only then is the clamping connection tightened by a pure rotational movement and thus the component and the bearing pin are simultaneously fixed to the spool body. In particular in this case the member constitutes one of the longitudinal ends of the finished tape reel.

The circumferential direction and the radial direction as used in this application always relate to the longitudinal axis of the spool body and thus of the entire tape spool.

Detailed Description

Fig. 1 shows a belt retractor 10 with a belt reel 12 which can be rotated in a retraction direction R by a reversible belt tensioner 14 integrated in the belt retractor 10 and a pyrotechnical belt tensioner 16 for pulling in a belt. The tape is wound in a middle section 17 of a spool body 18 of the tape spool 12 (see also fig. 2 to 4).

The belt tensioners 14, 16 provide a torque which is transmitted to the belt reel 12 via the entraining meshes 20, 22 which are fixed in rotation on the belt reel 12, so that it rotates. In the present example, the belt-tensioner 16 is assigned a belt-engaging part 20, while the belt-engaging part 22 can be coupled to the reversible belt-tensioner 14.

The coupling of the reversible belt tensioner 14 to the belt spool 12 is achieved by a coupling 24 (shown in detail in fig. 4). Overall, the coupling 24 follows known principles, in the event of the drive element 25 driven by the reversible belt tensioner 14 beginning to rotate, the coupling pawl 26 of the coupling 24 provided on the drive element 25 turns radially inward until it engages in the entraining engagement 22 on the belt reel 12 and thus effects a coupling in the take-up direction R. The specific design of the coupling 24 may be at the discretion of the skilled person, and is not relevant to the present invention.

The entraining engagement 22 is arranged on a component 28 which is connected by means of a clamping connection 30 to the reel body 18 in a rotationally fixed manner and in an immovable manner in the axial direction, i.e. along the longitudinal axis L of the tape reel 12.

In addition, the clamping connection 30 described here can be used to fix the entrainment engagement in tape reels 12 of different designs. Two examples are shown in fig. 2 and 3.

The member 28 here constitutes one longitudinal end (the right longitudinal end in fig. 2 and 3, respectively) of the tape spool 12.

The clamping connection 30 between the component 28 and the spool body 18 is formed by one or more clamping elements 34 on the component 28 and one or more complementary clamping elements 38 on the spool body 18, each clamping

element

34, 38 having a unique one of the wedge faces 36, 40, respectively, and the wedge faces 36 having a shape complementary to the wedge face 40, respectively.

In the example shown in fig. 4 and 5 and 8 to 11, three clamping

elements

34, 38 are provided, each having a single wedge surface 36, 40. The respective wedge faces 36, 40 are distributed uniformly over the member 28 and the spool body 18, respectively, in the circumferential direction U about the longitudinal axis L.

The number of clamping

elements

34, 38 is variable. Fig. 6 and 7 show examples in which exactly two or only one clamping

element

34, 38 are provided on the component 28 and on the reel body 18, respectively. The number of clamping

elements

34, 38 is always selected the same on the component 28 and on the reel body 18, and the distribution of the wedge faces 36, 40 in the circumferential direction U is also identical on both parts.

In this example, the member 28 has a central recess 42 (best seen in fig. 8) that defines an inner peripheral wall 44. The clamping element 34 is constructed integrally with the peripheral wall 44. The wedge surfaces 36 of the clamping elements 34 constitute a radially inner surface which occupies a major part of the circumferential wall 44.

The reel body 18 has, near the right axial end, a projection on which an outer circumferential wall is constructed, which has a clamping element 38 (not shown in detail). The wedge faces 40, which are complementary to the wedge faces 36, constitute a radially outer surface which occupies the majority of the peripheral wall of the projection.

Of course, it is also possible to reverse the arrangement and provide a recess on the reel body 18 into which the projection of the member 28 is inserted. The principle of action of the clamping connection 30 is implemented in the same way here.

Each wedge-face 36, 40 terminates in the circumferential direction U at a radial shoulder 46 where the radial extension of the respective wedge-face 36, 40 changes stepwise. In this example, all of the wedge faces 36, 40 start directly behind one of the radial shoulders 46.

In all wedge faces 36, 40, the wedge shape is configured only in the circumferential direction U and not in the longitudinal axis L. Radial dimension d of the respective wedge faces 36, 40₁、d₂Increases in amount along the circumference U up to the radial shoulder 46 where the wedge surface reaches its maximum dimension.

Each clamping

element

34, 38 and each wedge-shaped face 36, 40 extend in the axial direction, i.e. along the longitudinal axis L, over a clamping region 48 (see also fig. 8 and 9) having a dimension of about 2 to 25 mm.

In this clamping region 48, the radially inner or radially outer surfaces of the wedge surfaces 36, 40 lie flat against one another when the clamping connection 30 is established.

The peripheral walls on the member 28 and on the reel body each have a cylindrical surface in the clamping area 48, which means that the cross section of the circumferential surface does not vary along the longitudinal axis L in the clamping area 48.

The clamping area 48 on the component 28 and on the reel body 18 is selected here to be approximately as long.

The clamping element 38 and thus the wedge surface 40 on the spool body 18 have a shape complementary to the clamping element 34 and its wedge surface 36 on the member 28. The wedge-face 40 has the same curvature and a thickness d₂Along the thickness d of the wedge-shaped surface 36 over the circumference U₁The same draft, but of opposite magnitude, because wedge-faces 40 are oriented radially outward and wedge-faces 36 are oriented radially inward.

All wedge faces 36, 40 describe here a logarithmic spiral, the slope of which is the thickness d₁、d₂The increase in circumference U can be adjusted depending on the particular application and the clamping force to be achieved.

For the example shown in fig. 4 and 5, this means that each wedge surface 36, 40 forms an angle of approximately 120 ° in the circumferential direction U, and therefore in practice the entire circumferential surface of the outer circumferential wall on the reel body 18 and the inner circumferential wall 44 participate in forming the clamping connection 30.

To establish the clamping connection 30, the component 28 is slipped onto the axial end of the spool body 18, as shown in fig. 5, wherein the clamping

elements

34, 38 are positioned such that they have a radial play with the clamping

elements

38, 34 complementary thereto.

Now, the axial position of the member 28 can be adjusted relative to the spool body 18 by: the member 28 is moved relative to the spool body 18 along the longitudinal axis L within the clamping region 48.

The clamping area 48 in the member 28 and on the spool body 18 is selected to be sufficiently long so that adjustments can be made to compensate for tolerances in the millimeter range, in principle sufficient surface contact is always maintained between the wedge surfaces 36, 40 to ensure sufficient clamping force in the clamp connection 30.

When the desired position is reached, the member 28 and the spool body 18 are caused to rotate relative to each other in the circumferential direction U, where the member 28 is caused to rotate about the longitudinal axis L in the direction of rotation R. The wedge faces 36, 40 slide against one another, and the clamping connection 30 is tightened.

The member 28 and spool body 18 are combined in a circumferential position in which the radial shoulders 46 are sufficiently spaced from one another (i.e., in a position with sufficient radial clearance between the wedge faces 36, 40) so as not to create excessive frictional forces when the member 28 is sleeved onto the spool body 18.

After the clamping connection 30 has been established, the component 28 is connected to the reel body 18 in the circumferential direction U, in particular in a rotationally fixed manner relative to the direction of rotation R. Furthermore, the component 28 is fixedly connected to the reel body 18 in the axial direction, i.e. along the longitudinal axis L, by the frictional force of the clamping connection 30.

Member 28 may be made of a harder material than spool body 18. This makes the clamping element 34 stiffer than the clamping element 38 on the reel body 18 if the member 28 is manufactured in one piece. In this case, when the clamping connection 30 is tightened, the radially outer surface on the reel body 18 can be deformed to some extent, whereby the form-fit between the wedge faces 36, 40 is strengthened, since the clamping element 38 can be said to be slightly embedded in the radially outer surface of the reel body 18. The form-locking between the wedge-shaped surfaces 36, 40 is thereby strengthened.

Overall, when the clamping connection 30 is established, the wedge faces 36, 40 lie flat against one another over the largest extent of the circumference U and over the largest extent of the clamping region 48.

Although in the example just described three clamping

elements

34, 38 are provided on the component 28 and on the reel body 18, in the example of fig. 6 only two clamping

elements

34, 38 are provided, each having a single wedge surface 36, 40. Accordingly, each wedge-facet 36, 40 extends in the circumferential direction U over an angle of approximately 180 °. The inclination of the wedge faces 36, 40 in the circumferential direction U is selected to be lower than in the previous example, while the thickness d of the two clamping

elements

34, 38 is selected₁、d₂Are chosen to be equal.

Fig. 7 shows an example in which only one clamping

element

34, 38 is provided on the component 28 and the spool body 18, respectively, which has only one wedge surface 36, 40, respectively, which wedge surfaces 36, 40 each extend approximately 360 ° in the circumferential direction U. Where the thickness d is₁、d₂Is also equal to that in the first example, whereby the inclination of the wedge-facets 36, 40 in the circumferential direction U is further reduced compared to the example of fig. 6.

In general, more than three clamping elements can also be provided. In principle, the centering of the component 28 relative to the longitudinal axis L and the distribution of the occurring torques can be improved by increasing the number of wedge faces, while a stronger clamping effect can be achieved when the number of wedge faces is reduced.

And thickness d₁、d₂As well as the slope of the wedge faces 36, 40, the choice of the number of clamping

elements

34, 38 can be decided at the discretion of the skilled person.

At the axial end at which the component 28 is located, the tape reel 12 has a bearing pin 50 which extends along the longitudinal axis L and by means of which the end of the tape reel 12 on the right in the figure can be supported for rotation about the longitudinal axis L.

In a first variant, the bearing pin 50 is inserted into a receiving opening 52 (shown in fig. 5) in the reel body 18, which extends along the longitudinal axis L, for example by being pressed in with a small force, wherein the axial position of the bearing pin 50 is precisely determined.

The member 28 has in this case an end-side opening through which the bearing pin 50 passes when the member 28 is slipped onto the spool body 18. Here, the axial position of the support pin 50 does not change. The clamp connection 30 is tightened after the entraining engagement 22 on the member 28 has also been brought into its desired position relative to the longitudinal axis L. In particular, if the component 28 is made of a harder material than the reel body 18, the edge of the receiving opening 52, in which the bearing pin 50 is inserted, is also deformed when the clamping connection 30 is tightened, the material being pressed radially inwards and thus firmly surrounding the bearing pin 50. By tightening the clamping connection 30, the bearing pin 50 is simultaneously completely and finally fixed on the tape reel 12.

In a further variant shown in fig. 8 to 11, the bearing pin 50 is constructed integrally with the component 28 and constitutes its right-hand end in fig. 8. In this case, the bearing pin 50 is simultaneously automatically mounted onto the tape reel 12 when the clamping connection 30 is established. The axial position of the bearing pin 50 is determined simultaneously with the determination of the exact axial position of the entraining engagement 22 by changing the axial position of the component 28 relative to the spool body 18 before the clamping connection 30 is established.

If the entraining engagement 22 should be replaced or the tape spool 12 disassembled into its individual components for recycling, the member 28 can be separated from the spool body 18 by loosening the clamping connection 30 against the take-up direction R. On the other hand, under the action of force in the retraction direction R, the wedge faces 36, 40 slide relative to one another in such a way that the clamping connection 30 is further tightened by the increase in the slope of the interacting wedge faces 36, 40 and thus the clamping force is increased.
