Screed assembly with functional coupling between a height adjustment device for a screed plate carrier and a tilting device for a secondary screed plate attached to the screed plate carrier
Abstract A screed assembly (7) for a road paver (1) comprises a main screed (15) and a secondary screed (17). The main screed (15) comprises a main screed plate (23) for contact with paving material. The secondary screed (17) comprises a screed plate carrier (27) and a secondary screed plate (21) for contact with the paving material. The secondary screed plate (21) is attached to the screed plate carrier (27) so as to be tiltable about a tilting axis (41). The screed assembly (7) comprises a height adjustment device (31) configured to lower or raise the screed plate carrier (27) relative to the main screed (15). The screed assembly (7) comprises a tilting device (45) configured to change a tilting angle of the secondary screed plate (21) about the tilting axis (41). The height adjustment device (31) and the tilting device (45) are functionally coupled such that when the screed plate carrier (27) is lowered or raised relative to the main screed (15) by the height adjustment device (31), the tilting device (45) is automatically actuated to change the tilting angle of the secondary screed plate (21) about the tilting axis (41). Alternatively or additionally, the height adjustment device (31) and the tilting device (45) are functionally coupled such that when the tilting angle of the secondary screed plate (21) about the tilting axis (41) is changed by the tilting device (45), the height adjustment device (31) is automatically actuated to lower or raise the screed plate carrier (27) relative to the main screed (15).
