Description

Field of engineering

The invention initially relates to a summary of a take-up shaft for a truck body with an adapter part in order to be able to act on the take-up shaft via a drive shaft, the take-up shaft having a circular cross-section substantially in an adapted, extending in the axial direction of the take-up shaft and a Bottomed opening of the adapter part is introduced, wherein the take-up shaft in the longitudinal direction of the take-up shaft and from the outer surface inwardly extending groove, in which a driving projection of the adapter part, which is formed by a wall forming the opening, engages.

Also, the invention relates to an adapter part for a connection between a take-up shaft for a truck body and a drive shaft, wherein the adapter part has an axially extending and having a bottom opening and a cross-sectional inwardly directed driving projection, which is formed by a Opening wall.

State of the art

In particular in the field of truck bodies, such summaries or such adapter parts are known. For example, a truck tarpaulin can be wound up and unwound via a take-up shaft. The take-up shaft is connected to a drive shaft at least via an adapter part which is non-rotatably connected to the take-up shaft. The latter acts on the winding shaft via the adapter part in a rotationally driving manner. It becomes the state of the art by way of example on EP 1 378 385 B2 directed.

In particular, the non-rotatable connection of the adapter part and the take-up shaft considered about the longitudinal axis of the take-up shaft, the take-up shaft is provided with a groove extending in the longitudinal direction thereof into which a driving projection of the adapter part engages.

The winding shaft and the adapter part are plugged into each other in known solutions, for example. Using a hydraulic pressing device. It can be made hereafter additionally a form-fitting connection according to deformation in order to secure the adapter part to the take-up shaft in the axial direction. Thus, solutions are known in which an acting from the outside on the wall of the adapter part mandrel brings about such a form-fitting connection according to corresponding wall deformation of winding shaft and adapter part.

In addition, such a winding shaft is formed as an aluminum profile in the usual way. The adapter part is materially harder set relative to the take-up shaft, for example. This may be a cast steel part.

Summary of the invention

In view of the known prior art, the invention deals with the problem of further improving the positive connection between the take-up shaft and the adapter part.

With regard to the adapter part, the invention is concerned with the task of further improving such an adapter part in a manner advantageous to use.

A possible solution to both tasks is given in each case according to a first idea of the invention in a summary or an adapter part, which is based on the fact that the driving projection extends only over part of the given in the axial direction length of the opening, wherein the driving projection - seen from the Bottom of the opening - starts at a distance from the ground.

The in the summary position with the groove of the take-up shaft for rotatably connecting the take-up shaft and adapter part engaging in the groove of the take-up shaft of the adapter part, preferably does not extend beyond the axial depth of the take-up shaft or the adapter part side opening considered total depth of the opening, but only over a portion which, viewed in the axial direction, is shorter than the depth of the opening.

The axial distance between the bottom of the opening and a preferred parallel plane to the ground, which plane contacts the entrainment projection at the beginning thereof, may correspond to 0.5 to 2 times a maximum extent of the entrainment projection in the circumferential direction, moreover alternatively or in combination thereto one-tenth to one-third of the depth of the opening viewed in the axial direction.

The entrainment projection may start in the direction of the free opening area, that is, from the beginning spaced apart in the axial direction from the bottom of the opening. H. towards in the direction of the free edge of the opening forming wall of the adapter part be designed continuously. The driving projection may extend into the free opening area, alternatively terminating at an axial distance to this free opening area.

In addition, viewed in the axial direction, the driving projection can be composed of individual projections, between which regions of the wall of the adapter part which are not deformed into driving projections can extend.

According to the proposed solution is in the summary position of the bottom of the opening facing and preferably supported on the bottom of the opening end portion of the take-up of the adapter part side driving projection unaffected in the adapter part. It results in accordance with an end portion of the take-up shaft, in which the groove of the take-up shaft is exposed.

A further solution of the objects is given according to a further concept of the invention in both a summary and an adapter part, wherein it is based on the fact that the driving projection is essentially formed by the wall of the opening, under formation of cross-section at an acute angle with each other enclosing wall parts , which thus leave an acute-angled clearance between them.

The acute-angled orientation of the wall parts refers to a cross-section transverse to the extension of a longitudinal axis of the adapter part. The included angle can, for example, be between 15 ° and, for example, 75 °, preferably approximately between 30 and 60 °.

The wall parts enclosing the acute angle may have, with respect to the cross-section, a wall thickness substantially equal to the thickness of the wall otherwise surrounding the opening. Thus, the wall thickness of one of the acute angle enclosing wall portion - possibly even only partially - for example. 0.8 to 1.5 times, beyond possibly up to a 2 times the wall thickness in the circumferential direction outside the Correspond to the acute angle enclosing wall parts.

In the area of the trained driving projection, the wall is closed as a whole in the circumferential direction. The entrainment projection is, for example, formed by a wedge-like radial recess to the inside, wherein the resulting between the wall parts acute-angled free space viewed radially outward can be designed open.

The features of the above-described independent claims are each in each case substantially, as well as in any combination with each other, further features of an independent claim with the features of another independent claim or with features of several independent claims can be combined, also with only individual features of one or several of the further independent claims.

Further features of the invention are described below, also in the description of the figures, often in their preferred assignment to the claim concepts already explained above, but they can also be assigned to only one or more individual features, as described here, in particular the claims already dealt with , or independently or in another overall concept of importance. It is also possible to combine the measures of the claims already dealt with.

Thus, an inner surface which delimits the opening in the adapter part, on the bottom side of the opening closer to the longitudinal axis than in a contrast remote area to the ground. Measures may be taken correspondingly, which viewed in the axial direction and causes a reduction in the free cross-sectional area of the opening in the direction of the ground.

This cross-sectional reduction can be achieved in total by a corresponding approximation of the inner surface of the adapter part, based on the entire inner circumference. Also, this reduction can be given solely by in this, the bottom end facing the opening inside surface of the wall arranged ribs o. The like. Or formed, radially inwardly projecting elevations.

In a preferred embodiment, the inner surface extending from the bottom of the opening of the adapter part in the direction of the mouth surface of the opening is conically widening. It may, as also preferred, in this case be considered over the axial longitudinal extension uniform conical enlargement. The resultant cone may, as is preferred, relate to only a portion of the axial length of the wall surrounding the aperture, for example, starting from the bottom, over one tenth to one third of the axial depth of the aperture.

In a further embodiment, an exemplary conical extension may extend at least over the axial extent of the wall, which is free of a driving projection.

Next but also the driving projection in the direction of the opening may have a decreasing extent radially inward. The corresponding decrease can be in a magnitude match to that due to conical Enlargement over the height given decrease in the extent of the inner surface to be given radially inward. But it can also be stronger, for example, by 10 to 100% more or less, for example, by 10 to 50% amount less, done. Preferably, it is continuously given continuously.

Alternatively or additionally, an amount-wise decrease in the circumferential direction may also be present with regard to the driving projection. With respect to the area of the circumferentially projecting beyond the inner surface. Equal here means that it is an equal amount by which the inner surface recedes over the height with respect to a central axis toward the opening, irrespective of whether the inner surface combined has such a rejection or not. Also, the information regarding more or less are possible with regard to the extension of the driving projection in the circumferential direction in the same way as described with respect to the radial extent of the driving projection.

Thus, for a triangular cross-sectional area (which is unilaterally open, as indicated, preferred), there is an increasing uniform reduction toward the mouth of the opening.

By such a design of the driving projection, a positive connection in the insertion of the take-up shaft above the beginning of the driving projection seen from the bottom of the opening can result. This in addition or alternatively to the below-described compression of the shaft end in the adapter part for positive locking in the axial direction (pull-out direction).

As a result of the reduction in the opening cross-sectional area that results at the bottom, in a preferred embodiment, the bottom side of the opening has a free cross-sectional area of the opening which is smaller than the cross-sectional area of the take-up shaft viewed transversely to the longitudinal extent.

The wall of the adapter part may have one or more passage openings. Preferably, such a passage opening is formed on the bottom side of the adapter part side opening. Thus, by a through hole thus positioned, a check can be performed, for example, whether the take-up shaft is properly fully inserted and stopper limited by the bottom of the opening or is still in this proper position.

In addition, such a passage opening may be formed in the peripheral region of the wall of the adapter part, which also forms the driving projection. Thus, the example. Window-like passage opening may be formed in the axial extension of the driving projection in the wall. The axial extent of the passage opening can be adapted to the axial distance between the ground and the beginning of the driving projection.

The entrainment projection may extend from 1/10 to 1/3 of the diameter dimension of the opening with respect to an orifice area of the opening, starting from the inner surface of the wall. Thus, further, the radial extension dimension of the driving projection, starting from the inner surface of the wall, can correspond to approximately one quarter of a maximum extent of extension of the mouth surface of the opening.

The bottom of the opening may be formed in a possible embodiment of a central platform and a circumferential recess. Viewed in the axial direction, the depression can have a depth dimension of a few millimeters, for example 1 to 3 mm, relative to the support plane of the platform.

As mentioned, a take-up shaft is preferably formed as an aluminum profile shaft. This is preferably separated to length by sawing. An approximately protruding ridge o. The like. Along the peripheral edge can dive accordingly in the circumferential recess. The complete insertion of the take-up shaft into the opening of the adapter part up to the stop-limited end position given by the platform is not hindered.

The width of the recess measured in the radial direction may correspond to one-tenth to one-third of the diameter dimension of the opening, further for example about one-seventh to one-fifth.

In the allocation and utilization position, d. H. in the position of the take-up shaft pressed into the adapter part, a measure in the circumferential direction of the take-up shaft below the driving projection of the adapter part, ie. H. preferably in the takeaway projection-free region immediately in front of the bottom of the opening, be smaller than in the region of the entrainment projection and / or in a region of the take-up shaft extending outside the adapter part. This may, as also preferably, be achieved by the exemplary conical taper of the opening cross-sectional area towards the bottom of the opening. In the course of the preferred press-fitting of the take-up shaft into the adapter part, the end of the take-up shaft which is finally supported on the bottom of the opening or on the platform of the bottom is compressed.

The reduction of the dimension (circumferential dimension) can be achieved, as preferred, according to plastic and elastic deformation of the take-up shaft.

It may result in a reduction in the circumference of the take-up shaft by a fraction of a millimeter, for example. A reduction of one hundredth to one tenth, up to a millimeter.

The preferred compression of the shaft end in the adapter part leads to a deformation of the shaft-side groove outside the engagement of the driving projection of the adapter part in the groove of the take-up shaft. Thus, the opening dimension considered in the circumferential direction can decrease as a result of this compression, whereby (if necessary in addition) a pull-out protection of the take-up shaft in the axial direction can be achieved. This results in a positive locking in the axial direction.

With regard to the disclosure, the ranges and / or ranges of values or multiple ranges given above also include all intermediate values, in particular in 1/10 increments of the respective dimension, if appropriate also without dimension.

For example. the indication 1/10 to 1/3 also the disclosure of 11/100 to 1/3, 1/10 to 29/30, 11/100 to 29/30, etc. This disclosure can on the one hand to delimit a said range limit of below and / or above, but alternatively or in addition to the disclosure of one or more singular values from a respective specified range serve.

Description of the embodiments

Shown and described is first with reference to 1 a winding shaft 1 for a truck body, for example, for winding and unwinding a truck tarpaulin.

The winding shaft 1 is a total of rod-like with a substantially transverse to its longitudinal axis x considered circular cross-section.

The winding shaft 1 is preferably shaped as an aluminum profile.

From the outer surface of the take-up shaft 1 starting, extends radially inward a groove 2 , This groove 2 is in the longitudinal extension of the take-up shaft 1 viewed continuously formed.

With reference to a cross section through the take-up shaft 1 results in a substantially V shaped design of the groove 2 in the manner of a corresponding notch. The trapped by the groove flanks acute angle is about 30 ° in the embodiment.

The depth of the groove viewed radially inward from the outer wall 2 can, as shown, about one fifth of the outer diameter of the take-up shaft 1 correspond.

The winding shaft 1 is with a drive shaft 3 connect to. This is done between the take-up shaft 1 and the drive shaft 3 to be used adapter part 4 , In this adapter part 4 are the winding shaft 1 and the drive shaft 3 steckhalterbar.

While the connector between take-up shaft 1 and adapter part 4 preferably not after preparation of the connection, in particular not without tools, is detachable, the plug connection between the adapter part 4 and drive shaft 3 in a preferred embodiment, if necessary, can also be canceled without tools.

The assignment in use position is in successive rows along the longitudinal axis x, so that in a preferred embodiment body axes of the take-up shaft 1 , the drive shaft 3 and the adapter part 4 are arranged on a common axis.

The adapter part 4 is opposite the take-up shaft 1 made of a harder material, eg steel.

Essentially, the adapter part sits down 4 from an adapter section 5 for interaction with the drive shaft 3 and an adapter section 6 for interaction with the take-up shaft 1 together. The two adapter sections 5 and 6 are arranged in the direction of extension of the longitudinal axis x one behind the other and rotatably connected to each other in the circumferential direction. This is preferably achieved according to one-piece and uniform material configuration of the two adapter sections 5 and 6 ,

In the illustrated embodiment, the adapter portion extends 5 about more than a third of the entire length of the adapter part 4 in the extension direction of the longitudinal axis x.

The adapter section 5 has a square in a cross-section to the extension direction of the longitudinal axis x square insertion 7 on. The edge lengths of the here square opening area are adapted to the edge lengths of the adapter part 4 cooperating square end of the drive shaft 3 ,

It is so in the plug assignment one about the longitudinal axis x rotatable connection between the drive shaft 3 and adapter part 4 given. This non-rotatable connection can also by other non-circular cross-sectional shapes of the insertion 7 and the associated end of the drive shaft 3 be achieved, so for example. By an elongated rectangular shape viewed in cross-section or by waveform viewed in the circumferential direction.

At the in the illustrated embodiment also wall outside square or square-shaped adapter portion 5 closes the preferably substantially circular cylindrical adapter section 6 at. In the transition area between the adapter sections 5 and 6 is a transverse to the longitudinal axis x running floor 8th intended.

From the ground 8th proceeding circumferentially to the longitudinal axis x extends a wall 9 , This limits an opening 10 of the adapter section 6 ,

The wall 9 is essentially a circular cylindrical trained wall which is coaxial with the longitudinal axis x. The thereby limited in the circumferential direction opening 10 is towards the other adapter section 5 limited by the ground 8th , Turned away from the ground 8th results in an open mouth area 11 ,

The floor 8th is essentially composed of a with respect to the longitudinal axis x central platform 12 with a transverse to the longitudinal axis x aligned, planar contact surface 13 and one circumferential to the platform 12 aligned well 14 , This results in a groove-like depression 14 which is located between the inner surface of the wall 9 and the platform 12 extends.

The measured with respect to the longitudinal axis x radial width a of the recess 14 may be about one tenth of the diameter d of the opening 10 in the area of the mouth area 11 correspond.

The depth b considered in the axial direction of the depression 14 can be about half the width of the recess a 14 correspond.

The adapter part 4 is in the range of the adapter section 6 with a driving advantage 15 provided, for cooperation with the groove 2 the winding shaft 1 , In cooperation position as shown in 2 is so in the opening 10 taken up take-up shaft 1 opposite the adapter part 4 rotationally fixed in the circumferential direction.

The driving advantage 15 is essentially through the wall 9 the opening 10 formed, this under the formation of a cross-section acute angle α of about 30 ° enclosing wall parts 16 , These wall parts 16 are, for example, as shown in FIG 7 V-shaped aligned with each other, with a V-tip, which points radially inward in the direction of the longitudinal axis x.

It results so outward an acute-angled clearance 17 , which in the illustrated embodiment according to the 1 to 14 expires freely radially outward.

The radial board dimension c of the driving projection 15 , measured from the inner surface of the wall 9 radially inward, corresponds to about one fifth to one quarter of the diameter d of the opening 10 in the area of the mouth area 11 ,

According to the in the 1 to 14 shown first embodiment extends the driving projection 15 starting from the mouth area 11 receiving transverse plane of the adapter part 4 towards the ground 8th the opening 10 , The open space 17 is in this embodiment also to the mouth area 11 receiving level open.

Alternatively, the driving projection 15 - such as in 16 shown - with axial distance to the mouth area 11 receiving level of the adapter part 4 kick off. In this case, as shown, the free space 17 pointing in the axial direction to the above-described level to be covered by wall material.

The considered in cross-section material thickness in the region of the wall parts 16 preferably corresponds essentially to the material thickness of the otherwise circular cylindrical wall 9 ,

The driving advantage 15 is in a figurative sense in the form of a wedge-like depression of the wall 9 educated.

Starting from the mouth area 11 ends the driving projection 15 with respect to the extension in the longitudinal axis direction with axial distance to the contact surface 13 of the soil 8th or the platform 12 , This distance e (see 9 ) may, as also preferably, be about one fifth of the total effective receiving depth g of the opening 10 between the contact surface 13 and the mouth area 11 correspond.

So extends the driving projection 15 in the first embodiment, starting from the mouth surface 11 over a length f corresponding to about four-fifths of the total recording depth g.

In the longitudinal direction following the driving projection 15 is the driving-ahead 15 at the same time forming peripheral portion of the wall 9 penetrated by a passage opening 18 , This is with reference to a floor plan according to 10 , in which the longitudinal axis x is represented as a line, designed like a window with a rectangular plan, with an opening edge edge in the plane, which at the same time the bottom of the bottom recess 14 touched. The purpose for this purpose in the axial direction spaced and preferably parallel thereto extending edge of the passage opening 18 At the same time it can be the ground 8th axially spaced end edge of the driving projection in the axial direction 15 form.

The interrupted by the driving projection 15 or ground area side through the passage opening 18 in cross-section beyond circular inner surface 19 the wall 9 runs from the ground 8th , in the illustrated embodiment, in particular starting from the bottom of the recess 14 , widening conically in the longitudinal extension direction of the axis x. The cone area thus formed 20 extends in the axial direction preferably over the region of the passage opening 18 In addition, in the illustrated embodiment, a total of approximately starting from the ground 8th over a third of the recording depth g. It can be provided in this case a cone angle of a few degrees, so for example. A cone angle of 1 to 5 °.

The cone area 20 runs out into a circular cylindrical section of the inner surface 19 with a diameter dimension d adapted to the outer diameter dimension of the take-up shaft 1 , Accordingly arise in the cone area 20 towards the ground 8th decreasing diameter dimensions, all of which are smaller than the outer diameter dimension of the take-up shaft 1 ,

The inner surface 19 the wall 9 can, for example, in 15 represented in cross-section also be designed differently from a circular shape. Thus, in this regard, be considered in the circumferential direction waveform, with radially inwardly projecting elevations, which alternate in the circumferential direction with radially outwardly directed recesses. Projections and depressions may be waved into each other with respect to a cross-sectional area.

In particular, the raised, and thus radially inwardly facing areas, on which the lateral surface of the take-up shaft 1 partially supported in the assignment position, can go down to the ground 8th tapered rising.

The free end of the take-up shaft 1 is to be fixed with the adapter part 4 in the opening 10 of the adapter part 4 pressed in, according to this Insert the take-up shaft 1 in the axial direction, wherein the shaft-side groove 2 the adapter-side driving projection 15 receives. The V-shaped wall parts arranged to each other 16 the adapter part side wall 9 can on the facing surfaces of the shaft-side groove 2 concerns (cf. 11 ).

About the groove / projection connection are the take-up shaft 1 and the adapter part 4 rotatably connected.

Through the passage opening 18 is controllable from the outside, whether the ground 8th facing end face of the take-up shaft 1 properly on the platform-side contact surface 13 is present (cf. 13 ).

Due to the formation of the cone area 20 takes place in the corresponding end region of the take-up shaft 1 a material compression, along with a reduction in the circumferential dimension of the take-up shaft 1 in the projection-free region of the adapter part 4 ,

The circumferential dimension of the take-up shaft 1 becomes in the projection-free area, so on the axial dimension corresponding to the above-described distance e, with respect to the uninfluenced region of the take-up shaft 1 , for example in the area of the mouth area 11 , reduced by plastic and elastic deformation, so for example. In the circumferential direction, by up to 0.5 or 1 mm.

As a result, if necessary, an increased frictional engagement between the shaft-side surface and the inner surface 19 the wall 9 reached.

Also, by this material compression in the circumferential direction, a deformation in the region of the shaft-side groove 2 achieved, in particular in the form of a reduction of the free dimension of the groove considered transversely to the insertion direction 2 , The flanks of the groove 2 are plastically deformed towards each other in the area of the compression in the circumferential direction, this correspondingly in the projection-free region of the adapter part 4 , in particular in the region of the passage opening 18 ,

Due to the fact that, according to this deformation, the width dimension of the groove considered transversely to the direction of displacement 2 is reduced, this is a favorable way (optionally additional) trigger protection of the take-up shaft 1 from the adapter part 4 given. The adapter part-side driving projection 15 is engaged behind the constricted groove portion 2 the winding shaft 1 , which groove section 2 As a result, it acts as if it were blocking in the withdrawal direction (cf. 12 and 13 ).

The above explanations serve to explain the inventions as a whole, which further develop the state of the art independently, at least by the following feature combinations, namely:
