TRANSVERSE DISTRIBUTOR ARRANGEMENT FOR A ROAD FINISHER

Abstract

The present disclosure refers to a transverse distributor arrangement for a road finisher with a center console and counter-rotating augers, wherein the augers each extend from the center console to outer end regions with auger elements attached thereto and a base shaft. The base shaft is mounted in an outer bearing, the outer bearing being mountable at an attachment point via an outer bearing bracket. An extending shaft can be attached to the base shaft, or the base shaft can be replaced by a replacement base shaft of a different length than the base shaft. According to the disclosure, the base shaft and the outer bearing are detachably connected to each other, the same outer bearing in its state detached from the base shaft being detachably mountable on the extending shaft or on the replacement base shaft.

DETAILED DESCRIPTION

[0034] FIG. 1 shows a road finisher 2 and FIG. 2 shows a transverse distributor arrangement 1 of a road finisher 2. The transverse distributor arrangement 1 comprises an auger 4a arranged on the right-hand side in the direction of travel of the road finisher and an auger 4b arranged on the left-hand side. Both augers 4a, 4b are mounted centrally on a center console 3 and extend from the center console 3 to the outer end areas E. The center console 3 is attached to a body of the road finisher 2 (e.g., frame or structural element of the road finisher 2). In the housing formed by the center console 3 there is an auger-drive (not shown) for driving the two augers 4a, 4b.

[0035] Each auger 4a, 4b has a base shaft 6, which can be two individual shafts 6 or a common shaft 6, and one or more auger elements 5 are mounted on the base shaft 6. The outer end E of each base shaft 6 facing away from the center console 3 is supported by an outer bearing 7. Each outer bearing. 7 is mounted at the lower end of an outer bearing bracket 8, which is attached to a first attachment point 131, for example, by means of an attachment plate 17. This attachment point 131 can be located on a structural element 9 of the road finisher 2, which is stationary relative to the center console 3, or on a limiting plate 15. Which is attached to the structural element 9.

[0036] In order to reconfigure the transverse distributor arrangement 1 for different working widths, either the right-hand auger 4a, the left-hand auger 4b or both augers 4a, 4b can be extended. For this purpose, the outer bearing bracket 8 is detached from the first attachment point 131 on the structural element 9 or limiting plate 15 and the outer bearing 7 is detached from the base shaft 6.

[0037] FIG. 3 schematically shows the outer bearing 7 in its state of being detached from the base shaft 6.

[0038] To reconfigure the transverse distributor arrangement 1 for different working widths, an extending shaft 10 is attached to the base shaft. In addition, the outer bearing 7 in its detached state from the base shaft 6 is detachably mounted on the extending shaft 10 and the outer bearing bracket 8 is attached to a second attachment point B2 (see FIG. 4), which may be located on the structural element 9 or the limiting plate 15. Furthermore, one or more auger elements (not shown) may be mounted on the extending shaft 10.

[0039] FIG. 4 shows the outer bearing 7 in its detached state from the base shaft 6 and mounted detachably on the extending shaft 10. The outer bearing bracket 8 is now mounted at the second attachment point B2.

[0040] To reconfigure the transverse distributor arrangement 1 for different working widths, the outer bearing 7 is alternatively mounted in its detached state on a replacement base shaft 11, which is longer or shorter than the base shaft 6, in a detachable manner. In addition, one or more auger elements (not shown) may be mounted on the replacement shaft 11.

[0041] FIG. 5 shows the outer bearing 7 in its detached state from the base shaft 6 and then already detachably mounted on the replacement base shaft 11.

[0042] FIG. 6 shows an embodiment of the disclosure in which an outer bearing 7 is rotatably mounted with transition wings 12. In this embodiment, the transition wing 12 of the outer bearing 7 is mounted detachably and non-rotatably with a base shaft 6, an extending shaft 10 or a replacement base shaft 11. The detachable and non-rotatable connection between the transition wing and the shaft is created by means of connecting elements 13, disclosure screws or springs.

[0043] FIG. 7 shows an alternative embodiment of the disclosure with an outer bearing 7 and shafts 6, 10, 11 mounted on it in a connection that can be detached without tools.

[0044] FIG. 8 shows the spline profiles 14a, 14b of the outer bearing 7 and shafts 6, 10, 11 in front view. In order to create a connection between the outer bearing 7 and the shafts 6, 10, 11 that can be detached without tools and is rotationally fixed, the outer bearing 7 has, for example, a spline profile 14a that is designed to complement a second spline profile 14b of the base shaft 6, the broadened shaft 10 or the replacement base shaft 11 at their respective end areas E The spline profiles 14a, 14b can have different tooth shapes, disclosure polygon or classic hexagon.

[0045] In order to secure the connection between the outer bearing 7 and the shafts 6, 10, 1.1, which can be detached without tools, axial securing 16, disclosure a retaining ring, can be arranged.
