Patent number: 12351250Abstract: An auxiliary steering device for a hydrostatic vehicle steering system, includes an input shaft, which can be actuated or set in rotation by a steering wheel, an output shaft for actuating a steering metering valve, and a planetary gearing. The planetary gearing includes a planetary wheel carrier with multiple planetary wheels, which mesh with a sun gear and a surrounding ring gear. The input shaft is connected to the planetary wheel carrier and the output shaft is connected to the sun gear in each case for conjoint rotation. The auxiliary steering device has an electric drive for exerting a torque on the ring gear, a braking device for fixing the input shaft, and a coupling device for producing a rotationally fixed connection between the output shaft and the planetary wheel carrier.Type: GrantFiled: January 16, 2023Date of Patent: July 8, 2025Assignee: DEERE & COMPANYInventors: Stefan Brocke, Norbert Fritz, Richard Starck

Publication number: 20240278826Abstract: A hydrostatic steering device for an agricultural utility vehicle including a steering orbitrol, which can be controlled via a steering handle and by which a dual-action steering cylinder can be extended in accordance with a steering operation occurring at the steering handle. Depending on the operation direction of the steering handle, a first orbitrol connection forms a supply fed from a hydraulic high-pressure source, and a second orbitrol connection forms a return which communicates with a hydraulic reservoir, to actuate opposing working chambers of the steering cylinder. A hydraulic leakage flow occurring between the first and second orbitrol connections can be compensated with regard to a hydraulic operation of the steering cylinder via a valve assembly communicating with the high-pressure source and the hydraulic reservoir.Type: ApplicationFiled: February 5, 2024Publication date: August 22, 2024Inventors: STEFAN BROCKE, NORBERT FRITZ, RICHARD STARCK, JONAS GASSMANN, FABIAN HARTMANN
