Publication number: 20250067009Abstract: To pave a multi-layer road surface, a first pavement layer is paved along a roadway using a first road paver. A second pavement layer is paved over the first pavement layer using the first road paver or using a second road paver. Upon paving the first pavement layer, paving data is recorded that allows determining at least a progression track traveled during paving of the first pavement layer by a screed outer edge of the first road paver. The paving data is used to control the first road paver or the second road paver when the second pavement layer is paved.Type: ApplicationFiled: August 21, 2024Publication date: February 27, 2025Applicant: JOSEPH VÖGELE AGInventors: Tobias NOLL, Philipp STUMPF, Stefan SIMON, Ralf WEISER, Tobias GROLL

Publication number: 20250019913Abstract: The disclosure relates to a road paver comprising a towing vehicle, at least one tow arm, a screed assembly attached to a tow point of the tow vehicle via the at least one tow arm, a leveling cylinder adapted to adjust a position, in particular a height, of the tow point, a screed lifting cylinder adapted to adjust a contact pressure of the screed assembly, a first measuring device adapted to determine a screed height of the screed assembly, a second measuring device adapted to determine an attack angle of the screed assembly, and a feedback control device adapted to control the leveling cylinder and the screed lifting cylinder. The disclosure further relates to a method for feedback controlling a position of a screed assembly and a use of a feedback control device for feedback controlling an attack angle and a screed height of a screed assembly.Type: ApplicationFiled: July 12, 2024Publication date: January 16, 2025Applicant: Joseph Vögele AGInventors: Stefan SIMON, Ralf WEISER, Philipp STUMPF

Publication number: 20220290382Abstract: A road finishing machine with a screed for producing a paving layer on a subsoil includes a leveling system for height adjustment of the screed for compensating for irregularities in the subsoil. The leveling system includes a cascade control having either a central control loop between outer and inner control loops that includes a control unit to determine, on the basis of a detected actual value of a pulling point position of a pulling point of the screed to a predetermined reference, and on the basis of a desired value of the pulling point position, a desired value of a leveling cylinder position, or a pulling point control between the outer and inner control loops to determine, on the basis of the desired value of the pulling point position of the pulling point of the screed, the desired value of the leveling cylinder position.Type: ApplicationFiled: March 10, 2022Publication date: September 15, 2022Applicant: JOSEPH VOEGELE AGInventors: Stefan SIMON, Philipp STUMPF, Ralf WEISER, Martin BUSCHMANN

Publication number: 20220112669Abstract: A road finishing machine comprises a screed for producing a paving layer on a subsoil on which the road finishing machine is movable in a laying direction, wherein the screed has a pulling arm fixed to the road finishing machine at a front pulling point by a levelling cylinder; at least one measuring means for performing a distance measurement, a storage means, and a controlling system. The controlling system is embodied to calculate a correction value in response to at least one distance measurement performed with respect to the subsoil and/or to a reference, which is performable at a measuring point in front of a front edge of the screed, to at least temporarily store the correction value in the storage means and calculate a desired levelling value for the measuring point taking into consideration the stored correction value, based on which the levelling cylinder of the screed is controllable.Type: ApplicationFiled: October 8, 2021Publication date: April 14, 2022Applicant: JOSEPH VOEGELE AGInventors: Ralf WEISER, Philipp STUMPF, Stefan SIMON

Publication number: 20190177927Abstract: The disclosure relates to a road finisher with an undercarriage with two traction tracks. The road finisher further comprises a chassis, a hopper, mounted on the chassis at the front of the road finisher with respect to a paving direction, for receiving paving material, and a paving screed, provided on the rear of the road finisher with respect to the paving direction, for compacting the paving material. This paving screed is attached to the chassis through pulling arms. The road finisher also comprises a lifting device which is designed to lift the chassis relative to the undercarriage at least in a rear region of the road finisher. The road finisher further comprises a material deflector, which can be pivoted relative to the chassis, and that is arranged between the two traction tracks.Type: ApplicationFiled: December 12, 2018Publication date: June 13, 2019Applicant: JOSEPH VOEGELE AGInventors: Thomas SCHMIDT, Martin SEIBEL, Philipp STUMPF
