Patent number: 10730565Abstract: A fender assembly for an agricultural tractor including a carrier bracket which supports a wheel fender adjacent to a vehicle wheel. A steering mechanism is provided as part of the fender assembly, such that the wheel fender can be rotated relative to the carrier bracket. Accordingly, the rotation of the wheel fender can be controlled based on a steering signal generated by the vehicle steering system, to ensure that the wheel fender accurately follows the movement of the adjacent tractor wheel.Type: GrantFiled: October 29, 2019Date of Patent: August 4, 2020Assignee: AGCO International GmbHInventors: Thomas Maier, Erich Freytag

Patent number: 10526031Abstract: A fender assembly for a tractor, as well as a tractor having such a fender assembly. The fender assembly is constructed as first and second fender parts, connected via a rail. The rail has a partial spiral or helical shape. As a result, the second fender part is moveable on the rail along a path substantially parallel to a portion of the circumference of a wheel of the tractor, in a direction downwardly and outwardly relative to the first fender part. This provides a fender assembly allowing for improved access to tractor components located inboard of the fender assembly, as well as allowing for ease of access to the second fender part for an operator standing on the ground adjacent the tractor.Type: GrantFiled: November 6, 2017Date of Patent: January 7, 2020Assignee: AGCO International GmbHInventor: Erich Freytag

Patent number: 9254788Abstract: A vehicle folding rear view mirror support mechanism having first (15) and second (16) pivotally interconnected support arm means. A first end (15b1) of the first support arm means is pivoted on a mounting bracket (18) for attachment to the vehicle, a second end (15c1) of the first support arm means is pivotally connected with a first end (16b1) of the second support arm means, and a mirror mount (22) is pivotally connected to a second end (16c1) of the second support arm means. The first and second arm means (15, 16) are movable between a retracted reduced width position in which the two arm means are in a side by side substantially parallel relationship and an extended increased width position in which the two arm means are substantially end to end and the mirror mount (22) is supported at its maximum distance from the mounting bracket (18).Type: GrantFiled: November 19, 2013Date of Patent: February 9, 2016Assignee: AGCO INTERNATIONAL GmbHInventor: Erich Freytag

Patent number: 7413201Abstract: The invention discloses a utility vehicle, in particular an agricultural tractor, with a steering system having single-wheel-suspended steering wheels, which are mounted on a respective wheel carrier (11). Each wheel carrier (11) may be swivelled about the axis of at least one rigidly connected bolt (18) and is connected via a ball-and-socket joint (9) on the at least one bolt, to a transverse steering element (1) that is articulated to the vehicle body. Associated with the ball-and-socket joint (9) is a steering angle sensor (22) comprising a rotatable input member (23), which is located at least approximately in the extension of the axis of the swivel bolt (18). The rotatable input member (23) is connected to the bolt via an entrainment element (25) that transmits the swivel motion of the bolt in an angularly precise manner to detect the current swivel position of the wheel carrier (11).Type: GrantFiled: May 22, 2006Date of Patent: August 19, 2008Assignee: AGCO GmbHInventors: Erich Freytag, Bernd Glaser

Patent number: 6764526Abstract: A dry air filter for combustion engines of commercial vehicles with a device to produce compressed air, whereby the dry air filter (4) consisting of a filter housing (5) containing a filter cartridge (7) and a dust preliminary filtering stage (6), with an exhaust (8) for the dust discharged from the preliminary filtering stage which has a nozzle shaped section in which compressed air that is produced is blown through a conduit in the direction of the free opening by an ejector effect. In order that the air filter is easier to service and maintain, the compressed air is fed over a ring slot (28) into the exhaust (8) and is blown in the direction of the open outlet (21) for the purpose of creating an ejector effect to keep the exhaust free from dust. Compressed air is blown through the exhaust so that blockages cannot build up there nor in the area of the preliminary filtering stage. Specific, regular supervision of this area therefore becomes necessary.Type: GrantFiled: October 11, 2002Date of Patent: July 20, 2004Assignee: Agco GmbH & Co.Inventors: Erich Freytag, Gerd Rathke, Wolfgang Strodel
