Definitions
- the present invention relates to a road paver according to the preamble of claim 1.
- Road pavers are designed to produce a paving layer from a paving material such as asphalt and usually comprise a chassis and working units arranged on the chassis, such as a material hopper, a paving screed, a conveyor system, a cross-distribution arrangement.
- Road pavers have replaceable components, each of which is detachably attached directly to the chassis and/or to the working units by means of one or more screw connections, can wear out and must therefore be replaced at the end of their service life.
- Screw connections usually comprise a screw with a screw head and/or a screw nut.
- the screw head and/or the screw nut usually have a drive, for example a hexagon profile or a hexagonal outer or inner profile that can be driven with a wrench to loosen the screw connection.
- the problem is that the abrasiveness of the asphalt or other paving materials such as gravel can cause the screw heads and/or screw nuts that come into contact with the asphalt to wear out over time. This causes loss of material and shape on the surfaces of the screw connections.
- the outer contours of the screw connections or the screw heads and/or the screw nuts lose their angular shape and become rounded so that they can no longer be gripped using commercially available tools (for example socket wrenches, ring spanners, open-end wrenches, ratchets with nut attachment). This makes it much more difficult to replace the components at the end of their service life. If the fastening elements are worn/abraded to such an extent, the components must be laboriously separated from the working unit or chassis using an angle grinder.
- An asphalt paver with a distribution auger for distributing asphalt in front of a paving screed is known.
- One or more auger segments are coupled to a screw shaft via several fastening elements (bolts with bolt heads and nuts).
- DE 10 2022 102 095 A1 further discloses that the screw segment has a U-shaped receptacle for the fastening elements. The side walls of the receptacle extend straight from the body and define a recess or a U-shaped recess.
- DE 10 2022 102 095 A1 discloses that the bolt heads and nuts of the fasteners are countersunk in their respective recesses.
- the wear protection in particular the sacrificial body
- a one-piece component can be easier to handle and/or assemble.
- the one-piece component can be attached to the fastening unit without the need for an additional screw connection, for example by pressing the component onto the fastening unit.
- Such a component can have approximately the shape of a cap nut, which can be pushed onto the screw nut, in particular onto the cap nut, of the fastening unit.
- the victim's body can be attached to the fastening unit in a force-locking manner, regardless of whether it is in one piece or in multiple pieces.
- the force-locking connection allows the protective unit to be firmly mounted on the fastening unit or even completely prevents movement of the protective unit relative to the fastening unit. This in turn prevents friction between the victim's body and the fastening unit.
- a force-locking connection between the fastening unit and the victim's body can be detachable or be inseparable.
- a force-locking connection between the fastening unit and the sacrificial body can be made by means of screws or pressing the sacrificial body onto the edges of the screw head and/or the screw nut.
- a force-locking connection between the fastening unit and the sacrificial body can be made by elastic and/or plastic deformation of the sacrificial body, in particular at the edges of the screw head and/or the screw nut.
- the sacrificial body can be attached to the fastening unit in a form-fitting manner.
- the form-fitting connection between the sacrificial body and the fastening unit can be detachable or non-detachable.
- the form-fitting connection can be a snap/click connection.
- the inner contour of the sacrificial body and the outer contour of the fastening unit can each have a negative profile and a positive profile. The negative profile and the positive profile can interlock in such a way that movement of the sacrificial body relative to the fastening unit is prevented.
- the sacrificial body can be firmly bonded to the fastening unit.
- the firmly bonded connection can be a welded connection, a soldered connection or an adhesive connection.
- the sacrificial body can be cut out of a sheet of metal.
- the protective portion may substantially have the shape of a half-shell.
- a thickness/width of the half-shell may be the same along a length or a thickness.
- the protective portion may have an inner and an outer side. A distance between the inner side of the protective portion and the fastening unit may vary along the inner side.
- the protective section can essentially be designed in the form of a shield.
- the protective portion may have an upper end and a lower end.
- a first distance between the upper end of the protective portion and the fastening unit may be smaller than a second distance between the lower end of the protective portion and the fastening unit.
- the protective portion may extend radially from the lower end of the protective portion to the upper end of the protective portion.
- the lower end of the protective section may be connected to an outer surface of a working unit.
- the protective body can be designed as an extension of the component. This avoids additional work when mounting the protective body on the road paver or on a working unit of the road paver.
- the protective body can be attached separately from the component, i.e. as a separate component, to the road finisher, preferably to a working unit, in particular to a rotating working unit, or to the chassis of the road finisher. It is advantageous here that the protective body can be mounted/dismounted or replaced separately from the component.
- the protective body in particular the upper end of the protective section, can extend to an upper end of the fastening unit, in particular the screw head or the screw nut.
- the protective body, in particular the upper end of the protective section, can extend beyond the fastening unit, in particular the screw head or the screw nut.
- the protective body can be made of a steel with a hardness of at least 50 to 300 HBW, preferably 100 to 150 H BW.
- the protective body can comprise one or more wear-resistant composite materials. This can extend the service life of the fastening unit.
- the protective body can consist of one or more wear-resistant composite materials. This can extend the service life of the fastening unit.
- the protective body can have a wear-resistant cast alloy or be made of a wear-resistant cast alloy. This can extend the service life of the fastening unit.
- the wear-resistant cast alloy can be selected from the following group: Ni-Hard, EN-GJN-HV600, EN-GJN-HV600 (XCr18) or EN-GJN-HV600 (XCr23).
- paving material can be conveyed past several fastening units, for example from the material hopper through a material tunnel in a tractor of the road paver to the paving screed.
- a sacrificial body can be placed on all or some of the fastening units.
- a protective body can be arranged next to all or some of the fastening units.
- the cross distributor arrangement can have a shaft.
- the cross distributor arrangement can have a distributor screw that is detachably coupled to the shaft by means of the fastening unit.
- the distributor screw can have a main body attached to the shaft.
- the distributor screw can have a helical screw blade that extends from the main body and runs around the shaft.
- the distributor screw at least some segments thereof that come into contact with paving material, can be present as replaceable components of the road finisher, in particular the cross distributor arrangement of the road finisher.
- the fastening unit can extend perpendicular to a rotation axis of the shaft.
- the protective body can extend along a direction of curvature opposite to the direction of rotation of the screw blade. As a result, the protective body extends in the relative flow direction of the paving material conveyed by rotation of the screw blade. This in turn can reduce the abrasive forces on the protective body caused by the conveyed paving material and protect the protective body itself against wear.
- the protective body can be formed as a single piece with the distributor screw, in particular with the main body, in particular as a cast part. This avoids the effort required for additional assembly of the protective body on the transverse distributor arrangement.
- the protective body can be designed as a separate component separate from the auger. This means that the protective body can be replaced independently of the auger. This also makes it possible to manufacture the auger more cost-effectively.
- the protective body can surround at least a portion of the shaft.
- the protective body can extend radially around a portion of the shaft or run around a portion of the shaft.
- the protective body provides wear protection not only for the fastening unit but also for the shaft.
- the protective body can be attached to the shaft.
- a bottom part of the protective body extends along a circumferential surface of the shaft.
- the protective section is preferably arranged at a predetermined angle to the bottom part.
- the material hopper, a conveyor device of the road finisher for conveying the paving material from the material hopper to the cross distributor arrangement, the cross distributor arrangement or the paving screed can each be a working unit of the road finisher.
- the replaceable component can be a widening part of the paving screed for fastening to a screed base body of the paving screed.
- the replaceable component can be a pre-scraper for fastening to a screed base body of the paving screed.
- the replaceable component can be a channel plate for fastening to the chassis.
- the replaceable component can in particular be the distributor auger of the cross distributor arrangement.
- the use of the wear protection according to the invention is basically possible for attachment to those fastening units of the road paver which are used for the detachable fastening of a component and which can come into contact with the road paver during operation of the road paver with regard to the material movement caused thereto.
- Figure 1 shows a road finisher 1 for producing a paving layer 2 on a substrate 3.
- the road finisher 1 has a material hopper 4 at the front in the paving direction R, from which a paving material 6 received therein is transported to a paving screed 7 of the road finisher 1 by means of a longitudinal conveyor device 5 against the paving direction R of the road finisher 1.
- the longitudinal conveyor device 5 is arranged within a chassis 8 of the road finisher 1 and has a scraper belt 9 (see Figure 4 ).

- the transverse distribution arrangement 10 is designed to distribute the paving material 6 in front of the paving screed 7 transversely to the paving direction of travel R.
- FIG. 2 shows the road paver 1 in perspective.
- the paving screed 7 has a screed base body 11 and laterally extendable extension parts 12 in order to set a desired working width B of the paving layer 2 produced. By widening the paving screed 7 in this way, a larger working width B can be produced for the newly produced paving layer 2.
- Figure 4 shows the paving screed 7 in a schematic plan view with extended extension parts 12. By widening the paving screed 7 in this way, a larger working width B can be created for the newly created paving layer 2.
- Figure 4 shows that the cross-distribution channel 15 is extended sideways, beyond the plank base body 11. Along the widened cross-distribution channel 15, the paving material 6 thrown off by the scraper belt 9 can be transported to the outer sides of the extension parts 12. The inside of the cross-distribution channel 15 in Figure 4 arranged cross distributor arrangement 10 is also extended.
- the transverse distribution channel 15 installed in front of the paving screed 7 is supported at its outer areas transversely to the paving direction R by means of Channel plates 16 and pre-scrapers 17 attached to the side of the screed base body 11.
- the channel plates 16 and the pre-scraper 17 can be further extended sideways in order to extend the cross distribution channel 15. The same applies analogously to the cross distribution arrangement 10.
- Figure 5 shows the paving screed 7 with extended extension parts 12 and widening parts 18 attached to the sides to produce a very large working width B for the paving layer 2.

- Each auger bearing 22a, 22b is mounted at the lower end of a auger bearing bracket 23a, 23b.
- These auger bearing brackets 23 have a substantially vertically aligned tube 24a, 24b, which is attached to the chassis 8 of the road paver 1 by means of a fastening plate 25.
- the paving material 6 can comprise a cohesive mixture, such as asphalt, and/or unbound mixture, such as gravel.
- the asphalt mixture can consist of an aggregate mixture with a very high proportion of broken grains and preferably polymer-modified bitumen as a binding agent.
- Such paving materials 6 with hard grains rub against the fastening units 26 of the road finisher 1 that come into contact with the paving material (see Figure 7 , left: screw-nut connection, Figure 7 , middle: screw connection, Figure 7 , right: bolt-nut connection) and cause wear on the fastening units 26, so that the fastening units 26 cannot be easily loosened with a tool such as a wrench.
