Patent number: 8485322Abstract: A brake assembly comprises a brake ring piston (30) and at least one coupling (33?, 33). The brake ring piston (30) is provided with at least one channel (40, 43) through which a cooling agent can be supplied. The at least one channel leads to a surface of the brake piston which faces the at least one coupling.Type: GrantFiled: June 23, 2009Date of Patent: July 16, 2013Assignee: AGCO GmbHInventors: Johann Dobler, Sven Kreiger

Patent number: 8469157Abstract: A brake assembly is provided for a utility vehicle. After a brake operation, a clearance between a control member and an intermediate part and/or between a brake element and an intermediate part is adjusted by means of a displacement or restoring unit arranged in an intermediate part. Wear, and the associated change of clearance, can be compensated for by means of friction gripping devices, located respectively in the control member and in the brake element.Type: GrantFiled: July 13, 2009Date of Patent: June 25, 2013Assignee: AGCO GmbHInventors: Johann Dobler, Sven Krieger, Hajo Pargmann, Hans-Peter Zeiler

Publication number: 20110283687Abstract: An exhaust system for a vehicle having a cab (53) and an internal combustion engine (1) located in an engine compartment (51). The system includes an exhaust gas treatment unit (9) located outside the engine compartment and having an inlet (9a) which receives exhaust gases from the engine and an outlet (9e) which passes treated gases into a final portion (E) of the exhaust system. The treatment unit (9) is arranged to extend generally vertically with the outlet (9e) generally vertically above the inlet (9a) and adjacent a corner post (52) of the cab of the vehicle to reduce impact on the visibility from the cab. A cage (C) surrounds the exhaust gas treatment unit (9) and has a support means (12) for attachment to a chassis of the vehicle and an outlet (15e) which the outlet (9e) of the treatment unit is connected.Type: ApplicationFiled: December 7, 2009Publication date: November 24, 2011Applicant: AGCO GMBHInventors: Johann Dobler, Robert Heisler, Roman Bucher, Capelle Thorsten, Robert Honzek, Hans Heinle

Patent number: 7980365Abstract: A brake mechanism for a utility vehicle which can be installed around a drive shaft or inside a wheel hub. The brake has a non rotatable fixed body (200), a rotatable body (100) rotatable relative to the fixed body (200), at least one brake disc (207) which is non-rotatably relative to the fixed body (200), and at least one rotating brake disc (107) which is fixed for rotation with the rotatable body (100). An actuating member (234) can press the fixed brake disc (207) and the rotating brake disc (107) against each other and against a stop surface (209) on the fixed body to apply the brake. A spring means (230) also exerts an immobilizing force on the actuating member (234) to press the fixed brake disc (207) and the rotating brake disc (107) against each other to apply the brake.Type: GrantFiled: October 30, 2008Date of Patent: July 19, 2011Assignee: AGCO GmbHInventors: Klaus Bayer, Sven Krieger, Robert Honzek, Johann Dobler

Publication number: 20110120817Abstract: The invention relates to a brake assembly for a utility vehicle. After a braking operation a clearance between a control member (11) and the intermediate part (13) and/or between a brake element (12) and the intermediate part (13) is adjusted by means of a displacement unit (2) arranged in the intermediate part (13). Any change in wear and therefore any resulting change in clearance can be compensated for by means of a respective tensioning device (15, 15?), respectively located in the control member (11) and in the brake element (12), each of which are connected to the displacement unit (2).Type: ApplicationFiled: July 13, 2009Publication date: May 26, 2011Applicant: AGCO GMBHInventors: Johann Dobler, Sven Krieger, Hajo Pargmann, Hans-Peter Zeiler

Patent number: 6662923Abstract: A pressure plate assembly for a friction clutch includes a housing for mounting to a flywheel; a pressure plate, held in the housing with the freedom to move in the same direction as that of a rotational axis (A); a stored-energy element; and a wear-compensating device acting in the path of force transmission between the stored-energy element and the pressure plate, where the wear-compensating device has at least one adjusting element, which can move in an adjusting direction to compensate for wear. A clearance-producing arrangement includes a gripping element provided on the pressure plate, which element comes or can be brought to rest against a blocking element (fixed in position relative to the housing arrangement upon the occurrence of wear. When the housing arrangement is being attached to the flywheel arrangement, the blocking element arrives in state in which it is able to enter into a blocking interaction with the associated gripping element.Type: GrantFiled: October 3, 2001Date of Patent: December 16, 2003Assignee: Mannesmann Sachs AGInventors: Johann Dobler, Klaus Gorzitzke, Oswald Grünewald, Winfried Herterich, Jürgen Kleifges, Wolfgang Knauer, Jörg Lampe, Walter Lindner, Achim Link, Gerhard Röll, Reinhold Weidinger, Erwin Ziegler
