Embodiment Construction

[0026] figure 1 The road paver F shown in has a chassis 1 on an undercarriage and a paving hopper 3 at the front end of the chassis 1 . A main drive source 4 such as a diesel engine is installed in the chassis 1 behind the paving hopper 3 . An operator platform with a console housing computerized controls 5 is located behind the main drive source 4 . The regulation system R is incorporated or connected to the control device 5 . The adjustment system R or the control device 5 is equipped with a self-acquisition lay ratio controller R1 which then enlarges or reduces, ie increases or decreases, the earlier input for the adjustment system R to take into account. The lay ratio factor, eg when thickness correction measurements initiated by adjusting the leveling cylinder Z do not produce the desired result at all, or eg after a predetermined duration. In addition, the calculation part CB is provided in the adjustment system R. As shown in FIG. As with conventional paving machin...

Abstract

According to a method for constructing a cover layer S on a planum M by using a paving screed B the elevation of the paving screed B above the planum M is measured using a reference RZ on the planum M by at least one elevation sensors H and / or the lateral inclination of the paving screed B with respect to the planum M is measured by at least one lateral inclination sensor N. Upon occurrence of a deviation from the target elevation pulling points P of pulling bars 6 of the paving screed B are displaced vertically at a road paver F by levelling cylinders Z. Each levelling cylinder Z is exclusively adjusted over an absolute stroke starting from a selected zero point NP. The absolute stroke is calculated from a measuring result of a reference measurement and by consideration of a constructionratio factor. A new adjustment position of the levelling cylinder Z resulting from the adjustment over the absolute stroke in a self-learning fashion automatically is selected as the new zero point NP for a subsequent regulation cycle.

Description

technical field [0001] The invention relates to a method of laying overlays on a plane by using paving screeds drawn by a paving machine at tie rods, and to an adjustment system for, during the laying cycle of the overlay, relative to the Adjust the height position and / or lateral inclination position of the paving screed of the paver to the target value for the height or lateral inclination. Background technique [0002] In practice, there are various methods for correcting the thickness of the covering layer when laying traffic pavements. [0003] According to existing methods, elevation sensors are mounted at the front of the paving machine, at the rear end of the paving machine near the lateral distribution device, at the paving screed, and sometimes, at the tie bars of the paving fleet. A height sensor is used to measure the thickness by scanning a reference (eg routing wire or by a skid sliding on a flat surface). Then, based on the detected deviation (thickness too ...
