Abstract:
1. Paving screed for road pavers, comprising: a base screed and extension screeds each being supported by a guiding assembly having an extension guiding structure on a guiding arrangement located on the base screed, extension screeds being arranged at the front side or the rear side of the base screed and being slidably retractable and extendable in a direction parallel to the base screed, sole plates on the lower sides of the base screed and the extension screeds, towing bars on the base screed for floatingly towing the paving screed at an angle of attack (α) of the sole plates relative to a planum, a multiple point suspension on the guiding assemblies and located between the extension guiding structure and the base screed, a frame in the extension screed carrying the sole plate of the extension screed, at least two substantially vertical adjustment assemblies, spaced apart in the sliding direction of the extension screeds, the adjustment assemblies being activated by at least one drive, and engaging at the extension guiding structure for adjusting at least the height of the frame and the sole plate of the extension screed relative to the base screed, a lateral inclination adjustment assembly having at least one remotely controlled drive, and structurally separated from the adjustment assemblies, including a pivot hinge having a hinge axis oriented at least substantially perpendicular to the sliding direction and parallel to the sole plate of the extension screed, wherein the adjustment assemblies are positioned between the extension guiding structure and the frame of the extension screed, and the lateral inclination adjustment assembly is located between (i) the adjustment assemblies and the frame to which the sole plate of the extension screed is fixed, or (ii) between the frame to which the sole plate of the extension screed is mounted and the sole plate of the extension screed.
