Patent number: 11712962Abstract: A utility vehicle such as an agricultural tractor includes an engine, a heat exchanger, and a fan located under a hood. The hood is pivotable between a closed position and an open position. The fan is mounted to the hood such that, when in the closed position, the hood covers the engine and heat exchanger and the fan is positioned in an operable position to generate a cooling airstream through the heat exchanger. When the hood is in the open position, the fan is displaced from the operable position.Type: GrantFiled: December 13, 2021Date of Patent: August 1, 2023Assignee: AGCO International GmbHInventors: Thomas Maier, Erich Freytag

Publication number: 20220314501Abstract: An internally reinforced thermoplastic container has a body manufactured using rotational molding. Prior to molding, attachment elements are releasably attached to the interior surface of parts of a mold, and an initially separate tension member is connected between the attachment elements. The mold is closed and a body of the container molded such that the attachment elements are integrated into the walls of the body. After molding, the attachment elements are released from the mold. The attachment elements and the tension member define a tension structure to resist outward bulging of the container walls. The tension member may be tensioned prior to or after molding of the container body. The attachment elements may take the form of eyelets having a base incorporated into the wall of the container body. The method enables the formation of a hollow thermoplastic container with integrally formed internal reinforcement.Type: ApplicationFiled: March 31, 2022Publication date: October 6, 2022Inventor: Erich Freytag

Publication number: 20220203767Abstract: A tire has a carcass with a tread, a bead, a shoulder, and a sidewall. The bead, shoulder, and sidewall partially define a first internal cavity. At least one stiffening line for a pressurized fluid with a second cavity is within the carcass. The second cavity is aligned in an approximately transverse direction relative to the periphery of the tire. The second cavity is connectable to pressurized fluid supply system and can be inflated or deflated to adjust the stiffness of the tire. The stiffening lines may be inflated using a hydraulic fluid to increase the stiffness of the tire. Related wheels, vehicles, and methods are also disclosed.Type: ApplicationFiled: December 23, 2021Publication date: June 30, 2022Inventor: 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: 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
