Description
Technical field
The present invention relates to a kind of spool of tape especially in the restraint system of vehicle for the Webbing retractor of safety belt.
Background technique
Spool of tape can be coupled with belt tightener when needed, which rotate spool of tape in retracting direction, be made
Band is obtained in spool of tape.For this purpose, spool of tape usually have it is one or more drive engaging sections, the drives engaging section and
The longitudinal axis of spool of tape is arranged concentrically and by driving engaging section that driving force is transmitted to spool of tape from belt tightener.
This drive engaging section does not construct integrally usually for manufacturing technology reason with spool of tape, but constructs independent
Component on because it is for example made of high-strength material and generally also has complicated geometry.In order to have band
The component of dynamic engaging section is fixed in the spool body of spool of tape, the component be pressed on the axis of spool body so far and
Lock jail with being attached when necessary.
Summary of the invention
Task of the invention lies in simplify the manufacture of spool of tape and thus reduce cost.
The task is solved by the spool of tape with claim 1 feature.According to the present invention, the spool of tape includes using
In accommodate band, spool body with longitudinal axis and be arranged concentrically with longitudinal axis, be fixed on volume without relative rotation
Component on axis body, which, which has, drives engaging section.It is respectively equipped at least one on the component and spool body and clamps member
Part, the clamping element are configured to complimentary to one another, circumferentially extending lozenges.The component and spool body by
Clamping between lozenges is connected and is connected, and clamping connection can be established by component relative to the rotation of spool body.
But the clamping connection of spool of tape according to the present invention is neither bayonet connection is also not screw thread.With this connection phase
Than clamping element does not need axial grip face and clamping effect is only by the face contact in the circumferential direction between lozenges
It realizes.In the axial direction, i.e. axis, the primary retention between component and spool body are generated by frictional force along longitudinal direction
Clamp the clamping force of connection.
In order to engaging section be driven to be installed in spool of tape, only component need to be set in spool body and then make two portions
Part is pivotably movable with respect each other on clamping establishment of connection direction, clamps connection tightening herein.Connection is clamped to preferably comprise herein
It is uniquely coupled between component and spool body, to can usually save the component for example realized by lock jail or bonding in spool
Further fixing on body.After clamping connection and establishing, component about longitudinal axis not only with respect to direction of rotation and
Axial direction relative to axis along longitudinal direction firmly fixes.
Another advantage is that component can be made by relatively rotating spool body and component on the direction contrary with establishing
It is separated again with spool body.The different materials of component and spool body unquestionably can be separately recycled in this way or are for example existed
Unquestionably replacement drives engaging section in maintenance span.
Component preferably has the drive engaging section for reversible belt tightener, by the drive engaging section by driving energy from
Belt tightener is transmitted to spool of tape.Drive engaging section that can also for example be used for and its of pyrotechnic belt tightener or Webbing retractor certainly
The coupling of its component.
Power transmitting from belt tightener to spool of tape usually only carries out in the retracting direction in spool body in roll of strip.
It is advantageous to which lozenges is arranged in this way, so that it is consistent with the rotation direction to clamp establishment of connection direction.This to clamp
It is further tightened when being connected to belt tightener activation.It can also be tensioned in this way by clamping to connect unquestionably to absorb
Power act in the process, very high.
Two lozenges of the coefficient clamping element on component and spool body are configured to complimentary to one another, this meaning
Lozenges along the circumferential direction see gradient in radial directions for two contact lozenges amount having the same.Work as clamping
When establishing, clamping element advantageously mutual planar in the major part of circumference reclines for connection, with will pass through frictional force generate it is high
Clamping force.
It is preferred that each lozenges along the circumferential direction describes a helical about longitudinal axis.The helical especially can be logarithm
Helical.Clamping force obtained can be adjusted in a simple manner by the gradient of helical.The circumferentially extending maximum of lozenges
No more than 360 °.If multiple clamping elements are arranged on component or in spool body, all lozenges together on component or
Extend in spool body maximum no more than 360 °.Different lozenges is seen in the axial direction not to be overlapped, therefore helical is without axial
Component, i.e., without the form of screw thread.
Lozenges is especially with about circumferencial direction, in the axial direction, i.e. the constant geometry of axis is being pressed from both sides along longitudinal direction
Extend on tight region, spool body and the lozenges planar of component recline in the clamping region, to generate enough clamping forces.
Clamping region for example, about 2 to 25mm long.
Therefore, present invention provides compensate the axial tolerance between spool body and component.Component thus
It is nested with one another with spool body and is relatively moved in this way in clamping region range along axial before clamping connection is established, until
Reach its desired relative position.
Preferred means or spool body have the recess equipped with internal perisporium, at least one is arranged on the internal perisporium and clamps member
Part, and spool body or component have periphery wall, at least one complementary clamping element is arranged on the periphery wall.
Clamping element and therefore lozenges preferably integrally construct with spool body and component corresponding (inner or outer) respectively
On peripheral wall.The each lozenges for clamping connection advantageously forms inner radial surface or radially-outer surface herein, this depends on the wedge
Shape face is setting in spool body or on component.The mutual planar of radial surface reclines, and thus generates clamping force.
The lozenges of all clamping elements in preferred means or in spool body occupies most of week of corresponding component respectively
To face.
At least one axial section of clamping region --- the mutual planar of lozenges reclines wherein --- including peripheral wall.
In clamping region, the circumferential surface on component or in spool body equipped with lozenges preferably comprises cylindroid,
There is in axial direction constant cross section on entire clamping region.
In the cross section of the longitudinal axis perpendicular to corresponding peripheral wall, in the circumferential direction round envelope portion especially with it is vertical
It is concentric to axis.
In a preferred embodiment, a unique clamping element is only set respectively on component and in spool body,
It is with unique lozenges.But can also on component and spool body on be arranged it is multiple, especially two or three be respectively provided with
The clamping element of unique lozenges, they are arranged with being distributed on the circumferencial direction around longitudinal axis.
Using unique clamping element, preferably circumferentially extending about 360 ° of lozenges.Make
When with two clamping elements, circumferentially extending about 180 ° of preferably each lozenges, and using three clamping elements
When, correspondingly preferably circumferentially extending about 120 ° of each lozenges, so that whole circumference length can be used for lozenges.?
It is contemplated that the clamping element of setting three or more.Generally speaking, the centering more balanced can be realized by increasing the quantity of lozenges
And moment distribution, and each single lozenges can be made to obtain lower helical angle and therefore realize using small number of lozenges
Better clamping effect.Clamping connection, the careful design of length and distribution be circumferentially in the circumferential direction about lozenges
The quantity of clamping element and lozenges is decided in its sole discretion by technical staff.
Due to usually driving engaging section to be made of the material harder than spool body, it is frequently advantageous that with the material system
Entire component is made, so that component is made of the material harder than spool body.It herein can be advantageously, entire component includes driving to nibble
It is integrally manufactured including conjunction portion.Difference based on material hardness, the lozenges on component can be partially sinked in the wedge shape in spool body
In face, thus improve form locking.But the primary retention of fixation of the component in spool body passes through mutually always in the case
The frictional force of the lozenges that planar reclines rather than realized by forming axial step.
In the second function other than drive engaging section fixed in spool body, which can be used for consolidating fulcrum post
It is scheduled in spool of tape, which constitutes the end side supporting member of spool of tape, for rotating spool of tape around its longitudinal axis.
The first possibility is that fulcrum post and longitudinal axis are concentrically disposed in spool body, clamps establishment of connection
Reinforce fixation of the fulcrum post in spool body.Fulcrum post is directly installed in spool body in the case.
Such as in the receiving opening that fulcrum post can be inserted into spool body first.When make-up is between component and spool body
When clamping connection, power is then acted against on the edge of receiving opening, which is pressed in one for the edge for accommodating opening and fulcrum post
It rises and therefore increases the fixed force acted on fulcrum post.In the case, component is made of the material harder than spool body
It is also advantageous, to ensure the fully deformed at the edge of the opening in spool body.It can usually save for example by being previously applied to
The additional bonding connection that microencapsulation adhesive on fulcrum post is realized.
Fulcrum post can be pressed into first when necessary and accommodated in opening, relatively low pressure can be used herein, this allows to have needle
Determine the insertion depth of fulcrum post, to property for example to compensate axial tolerance.In this positioning of fulcrum post, the fulcrum post
It is substantially inflexible.Clamping connection only is tightened by relatively rotating the lozenges of spool body and component, the material of spool body is
It is pressed together in radial directions around fulcrum post, thus acts on the fixed force on fulcrum post compared to directly in indentation
State afterwards dramatically increases.It is only established by radial force due to clamping connection, without axial force, axis is acted on along longitudinal direction
On fulcrum post, thus fulcrum post no longer in axial direction moves.
Another possibility is, fulcrum post is arranged on component, and fulcrum post is concentrically set with longitudinal axis on component
It sets and then fulcrum post is fixed in spool body by the clamping connection by component in spool body.It is preferred that fulcrum post is in this feelings
It is integrally constructed under condition with component.Connection is clamped by tightening, fulcrum post is also mounted simultaneously and the folder based on centering
It is tightly connected in automatic correct centering to longitudinal axis.
The accurate axially position of fulcrum post can pass through axis of the adjustment means relative to spool body before tightening clamping connection
It is realized to position, mode are as follows: by making lozenges in clamping region axially with respect to moving slightly from one another, until reaching
To desired fulcrum post axial position.Then it is just tightened by pure rotary motion and clamps connection and therefore by component and branch
It consigns and is also secured in spool body.Especially in the case component constitute finished product spool of tape one of longitudinal end.
The circumferencial direction and radial direction used in this application is always related to the vertical of spool body and therefore entire spool of tape
To axis.

Conjunction portion 20,22 is transmitted in spool of tape 12, so that the spool of tape rotates.In this example, engaging section 20 is driven to be allocated to pyrotechnics
Formula belt tightener 16, and drive engaging section 22 that can then couple with reversible belt tightener 14.
Reversible belt tightener 14 and the coupling of spool of tape 12 are realized by connector 24 (being shown specifically in Fig. 4).Total
For connector 24 follow known principle, the driving element 25 driven by reversible belt tightener 14 rotate when, setting exist
The connection pawl 26 of connector 24 in driving element 25 radially-inwardly rotates, until the drive that it is embedded in spool of tape 12 is nibbled
In conjunction portion 22 and therefore the coupling on retracting direction R is realized.The specific design of connector 24 can voluntarily be determined by technical staff
It is fixed, it is unrelated to the invention.
Drive engaging section 22 is arranged on component 28, and the component is by clamping connection 30 and spool body 18 without relative rotation
And it in the axial direction, is immovably connected along the longitudinal axis L of spool of tape 12.
In addition, clamping connection 30 described herein can drive engaging section for fixed in the spool of tape 12 of different designs.
Two kinds of examples are shown in figs 2 and 3.
Component 28 constitutes a longitudinal end (being right longitudinal end respectively in figs 2 and 3) for spool of tape 12 herein.
Clamping connection 30 between component 28 and spool body 18 is by one or more clamping elements 34 on component 28
Clamping element 38 formation complementary with the one or more in spool body 18, each clamping element 34,38 are respectively provided with uniquely
One lozenges 36,40 and lozenges 36 is respectively provided with the shape complementary with lozenges 40.
Three clamping elements 34,38 are respectively set in the example shown in Figure 4 and 5 and 8 to 11, they are respectively provided with only
A lozenges 36,40 one by one.Each lozenges 36,40 is respectively equably along around longitudinal axis L on component 28 and spool body 18
Circumferencial direction U distribution.
The quantity of clamping element 34,38 is variable.Such example is shown in figs. 6 and 7, wherein in 28 He of component
Exactly two or only one only one clamping element 34,38 are respectively set in spool body 18.But in component 28 and spool body 18
On always select the quantity of clamping element 34,38 and the along the circumferential direction U of lozenges 36,40 in both parts in the same manner
Distribution is also consistent.
In this example, component 28 has central recess 42 (high-visible in fig. 8), limits internal perisporium 44.It clamps
Element 34 is integrally constructed with peripheral wall 44.The lozenges 36 of clamping element 34 constitutes inner radial surface, occupies the big of peripheral wall 44
Part.
Spool body 18 has protruding portion near the axial end portion of right side, and periphery wall, the periphery are constructed on the protruding portion
Wall has 38 (not shown in detail) of clamping element.The lozenges 40 complementary with lozenges 36 constitutes radially-outer surface, occupies prominent
Most of peripheral wall in portion out.
Certainly, which can also be arranged to recess in turn and in spool body 18, the protruding portion insertion of component 28 should
In recess.The action principle for clamping connection 30 is realized in the same manner herein.
Along the circumferential direction U is terminated at radial shoulder 46 each lozenges 36,40, the corresponding lozenges at the radial direction shoulder
36, it 40 radially extends and changes stepwise.In this example, all lozenges 36,40 directly start from a radial shoulder 46
Later.
In all lozenges 36,40, only along the circumferential direction U is constructed wedge shape without axis L along longitudinal direction.Corresponding lozenges
36,40 radial dimension d1、d2Amount circumferentially U is increased up radial shoulder 46, the lozenges reaches it most at radial shoulder
Large scale.
Each clamping element 34,38 and each lozenges 36,40 are in the axial direction, i.e. along longitudinal direction axis L is in pinch zones
Extend (referring also to Fig. 8 and 9) on domain 48, which has about 2 to 25mm size.
In the clamping region 48, when clamping connection 30 is established, the inner radial surface or diameters that be made of lozenges 36,40
Recline to the mutual planar of exterior surface.
Peripheral wall on component 28 and in spool body has cylindroid in clamping region 48 respectively, this indicates circumferential surface
Axis L does not change along longitudinal direction in clamping region 48 for cross section.
Clamping region 48 on component 28 and in spool body 18 selects to obtain much the same length herein.
Clamping element 38 in spool body 18 and therefore lozenges 40 have and the clamping element 34 and its wedge on component 28
The complementary shape in shape face 36.The curvature having the same of lozenges 40 and thickness d2The thickness with lozenges 36 is followed on circumference U
Spend d1Identical gradient, but there is opposite amount, because lozenges 40 is radially outward directed, and lozenges 36 is radially-inwardly fixed
To.
All lozenges 36,40 describe a logatithmic spiral, the gradient of the helical, i.e. thickness d herein1、d2On circumference U
Increase and can be adjusted according to specific application and clamping force to be achieved.
For example shown in Figure 4 and 5, this indicates that along the circumferential direction U constitutes about hexagonal angle to each lozenges 36,40
Degree, and therefore the entire peripheral surface of actually internal perisporium 44 and the periphery wall in spool body 18 is involved in composition clamping connection
30。
Clamp connection 30 to establish, as shown in figure 5, component 28 is set on the axial end portion of spool body 18, herein this
Sample positions clamping element 34,38, so that they have radial clearance with the clamping element 38,34 being complementary.
It now, can be relative to the axial position of 18 adjustment means 28 of spool body, mode are as follows: make structure in clamping region 48
Axis L is mobile along longitudinal direction relative to spool body 18 for part 28.
Clamping region 48 in component 28 and in spool body 18 is selected enough to length, so that can be adjusted to compensate milli
Tolerance in rice range, sufficiently keeps face contact between lozenges 36,40 in principle always, to ensure to clamp 30 mesopodiums of connection
Enough clamping forces.
When the desired position is reached, making component 28 and spool body 18, along the circumferential direction U rotates relative to each other, makes herein
Component 28 is rotated around longitudinal axis L in the direction of rotation R.It is mutually slided in this lozenges 36,40, simultaneously clamps on connection 30 and receive
Tightly.
Component 28 and spool body 18 are combined in such circumferential position at this, and radial shoulder 46 is each other in this position
It is spaced sufficiently apart (in the position i.e. between lozenges 36,40 with enough radial clearances), so that component 28 is being set to volume
Excessive frictional force is not generated when on axis body 18.
Establish clamp connection 30 after, component 28 along the circumferential direction U especially relative to direction of rotation R without relative rotation
Ground is connect with spool body 18.In addition, component 28 in the axial direction, i.e. along longitudinal direction axis L by clamp connection 30 frictional force
It is fixedly connected with spool body 18.
Component 28 can be manufactured by the material harder than spool body 18.If component 28 integrally manufactures, this to press from both sides
Tight element 34 is harder than the clamping element 38 in spool body 18.In the case, when tightening clamping connection 30, in spool body
Radially-outer surface on 18 can occur centainly to deform, and thus strengthen the form locking between each lozenges 36,40, because can be with
Say that clamping element 38 is slightly embedded in the radially-outer surface of spool body 18.Thus the shape lock between lozenges 36,40 is strengthened
It closes.
Generally speaking, when clamp connection 30 establish when, lozenges 36,40 planars on the maximum magnitude of circumference U and
Mutually recline on the maximum magnitude of clamping region 48 to planar.
Although three clamping elements 34,38 are arranged on component 28 and spool body 18 in the example just described,
Two clamping elements 34,38 are only set in the example of Fig. 6, they are respectively provided with only one lozenges 36,40.Correspondingly, often
Along the circumferential direction U extends about 180 ° of degree angles to a lozenges 36,40.The gradient of the along the circumferential direction U of lozenges 36,40 selects low
In former example, and the thickness d of two clamping elements 34,381、d2Full-size be selected as it is equal.
Fig. 7 shows a kind of example, and only one clamping element is only arranged respectively on component 28 and spool body 18 wherein
34,38, it is respectively provided with only one lozenges 36,40, along the circumferential direction U extends about the lozenges 36,40 respectively
360°.In this thickness d1、d2Full-size it is also equal in the first example, the along the circumferential direction U of lozenges 36,40 as a result,
Gradient further decreased compared with the example of Fig. 6.
In general, it may also set up more than three clamping element.Structure can be improved by increasing the quantity of lozenges in principle
Part 28 can be realized more relative to the centering of longitudinal axis L and the distribution of occurred torque when the quantity of lozenges is reduced
Strong clamping effect.
With thickness d1、d2Full-size as the gradient of lozenges 36,40, clamping element 34,38 quantity selection can
It is decided in its sole discretion by technical staff.
