Patent number: 7631886Abstract: A trailer coupling for tractive vehicles, in particular agricultural tractors, consisting of two vertical guidance cheeks (7), fitted with lateral spacing to the rear of the vehicle, the guidance cheeks including vertical slots (7a) and a bearing member (11) held detachably at the lower end region of the guidance cheeks, on which a coupling member (12) is arranged for attaching an implement. In the case of a prior art trailer coupling, all forces transmitted from the attached implement to the coupling member used, a ball coupling (12) for example, are conducted via the bearing member (11) into the guidance cheeks (7). Thus this involves the undesirable necessity of having to dimension the guidance cheeks in a robust manner, which in turn leads to space problems within the tail end region of the vehicle. Therefore a trailer coupling is to be created which reduces the load on the guidance cheeks (7), when the forces of the attached implement are conducted into the rear of the vehicle.Type: GrantFiled: August 8, 2007Date of Patent: December 15, 2009Assignee: AGCO GmbHInventors: Johannes Kapfer, Gottlieb Wolfle

Publication number: 20090224511Abstract: This invention is related to a retractable hitch-ball mechanism adapted for coupling to a frame of a vehicle, such as a pickup truck. The mechanism includes a support structure that is secured to the frame by a mounting-frame assembly, a housing having a tubular sleeve, a hitch ball member slidably disposed within the tubular sleeve, a drive plate, and a linkage coupled to the drive plate at one end and having a user-engageable portion at an opposed end. Upon a user exerting force on the opposed end, the hitch ball member is selectively movable between an extended use position, wherein a portion of the hitch ball member extends upwardly from the tubular sleeve, and a retracted storage position, wherein the ball portion is substantially hidden. Selective adjustment is facilitated by an inclined edge on the drive plate that slidably engages at least a portion of the hitch ball member.Type: ApplicationFiled: March 10, 2008Publication date: September 10, 2009Inventor: Bernard L.
