Patent number: 6959935Abstract: A steering triangle (1) is provided for the axle suspension of motor vehicles for the articulated connection of a vehicle axle with a vehicle chassis with two control arms (2, 3). The control arms are connected to each other in a joint housing (6) formed by the control arms (2, 3) together for a rubber-metal bearing (11) for fixing the steering triangle (1) on the vehicle axle. The rubber-metal bearing (11) has a pivot axis (12) provided with a spherical surface and an elastomer body (14), which extends around the pivot axis (12) at least in the area of the spherical surface and which is accommodated in a recess (16) located within the joint housing (6), in which steering triangle two pressing rings (17, 18) are arranged within the recess (16) of the joint housing (6) on the axial outer sides of the elastomer body (14). The pressing rings can be moved toward each other by a tensioning device via the intermediary of stop faces (22) of the joint housing (6).Type: GrantFiled: February 3, 2004Date of Patent: November 1, 2005Assignee: ZF Lemförder Metallwaren AGInventors: Reinhard Buhl, Reinhard Richter, Uwe Cossmann, Ralf Kunze, Holger Bublies, Sören Knopp

Patent number: 6637762Abstract: An axle suspension for rigid axles of vehicles, especially air-cushioned utility vehicles includes a twistable fur-point connecting rod (4) connected above the vehicle axle (3) to the (vehicle axle (3). The twistable four-point connect rod (4) is connected to the vehicle chassis (1a, 1b, 2a, 2b) via two said joints (5, 6, 7, 8) each, which are arranged at spaced locations from one another in the longitudial direction of the vehicle. At least one spring assembly unit (19, 20) per vehicle side is located for spring suspension between the vehicle axle (3) and the vehicle chassis (1a, 1b, 2a, 2b). An axle strut (21) for axle guiding, extends approximately in the middle of the vehicle in the longitudinal direction of the vehicle and connects the vehicle axle (3) to the vehicle chassis (1a, 1b, 2a, 2b) in a vertically movable manner.Type: GrantFiled: August 15, 2001Date of Patent: October 28, 2003Assignee: ZF Lemförder Metallwaren AGInventors: Holger Bublies, Reinhard Buhl, Uwe Cossmann, Reinhard Richter, Werner Schmudde

Patent number: 6129367Abstract: An axle suspension for rigid axles in vehicles, especially utility vehicles, with longitudinal control arms extending in the longitudinal direction of the vehicle and connecting the vehicle axle to the vehicle body in a vertically movable manner. The longitudinal control arms are arranged for axle guiding on each side of the vehicle approximately at the same level. A four-point torsional connecting element is articulated to the vehicle axle, on the one hand, and to the vehicle body, on the other hand. The four-point torsional connecting element is arranged above the vehicle axle and is connected as a flexible cross to the vehicle axle and to the vehicle body via two body and axle joints located at spaced locations from one another in the transverse direction of the vehicle. The arms of the four-point connecting rod are designed in whole as a one-piece forged part and are girders subject to bending with an approximately rectangular cross section. One of the arms has a predetermined breaking point.Type: GrantFiled: June 5, 1998Date of Patent: October 10, 2000Assignee: Zf Lemforder Metallwaren AGInventors: Holger Bublies, Reinhard Buhl, Uwe Cossmann
