Patent number: 6241225Abstract: A rubber bearing, especially for the bearing support of a stabilizer bar in a motor vehicle, comprises two rubber half-shells. A thin rubber connecting piece connects the longitudinal side of one of the half-shells with the longitudinal side of the other one of the half-shells. The rubber connecting piece is arranged at the radial outer region of the half-shells to enable 180° of rotation of one of the half-shells with respect to the other one of the half-shells about the area of connection.Type: GrantFiled: March 11, 1998Date of Patent: June 5, 2001Assignee: Mannesmann Boge GmbHInventor: Wolfram Krause

Patent number: 6220584Abstract: A hydraulically damping engine bearing having fluid-filled chambers bordered at least partially by elastic walls, a limitedly deflectable diaphragm separating the chambers, and at least one channel connecting the chambers. A bearing spring rate characteristic is adjustable by an arrangement that includes an additional suspension spring arranged outside of one of the chambers. An intermediate space is bordered by the suspension spring together with an outer wall of one of the chambers. A valve, in communication with the intermediate space, enables the space to be aerated and de-aerated.Type: GrantFiled: March 24, 1999Date of Patent: April 24, 2001Assignee: Mannesmann Boge GmbHInventor: Heinrich Meyer

Patent number: 6109400Abstract: An impact absorber for decelerating a vehicle during a collision with an obstacle by hydraulic damping forces and pneumatic spring forces includes two tubes that are telescopically displaceable one inside the other. An internal tube of the two tubes is closed off to the outside by a base. A gas space subjected to high pressure is disposed adjacent said base and interacts with a first liquid space via a separating piston which is axially guided in the internal tube in a sealed manner. The first liquid space is hydraulically connected to a second liquid space via a throttle opening through an intermediate wall attached inside the internal tube. A working piston attached to a piston rod is guided in the internal tube in a sealing manner and interacts via the piston rod with a third liquid space in an external one of the two tubes. A control which can be connected to two chambers is provided to extend the impact absorber or to return it to a normal position.Type: GrantFiled: July 9, 1997Date of Patent: August 29, 2000Assignee: Mannesmann Boge GmbHInventors: Metin Ayyildiz, Holger Kirchner

Patent number: 6027105Abstract: An impact damper includes two tubes which are slidable one in the other for braking a vehicle impact against an obstacle by hydraulic damping forces and pneumatic spring forces. The inner tube is closed off by a bottom. A gas chamber containing a high pressure gas cushion is arranged adjacent to the bottom and bounded by a separating piston that is guided sealingly and displaceably in the inner tube. A first fluid chamber is arranged between the separating piston and a partition fixed in the inner tube and provided with choke openings. A second fluid chamber is formed by the outer tube and connected to the first fluid chamber via the partition. The outer tube has a tapering region directed away from the partition, and a deformation element dividing the second fluid chamber into two part chambers.Type: GrantFiled: June 30, 1998Date of Patent: February 22, 2000Assignee: Mannesmann Boge GmbHInventors: Wolfgang Dohrmann, Metin Ayyildiz

Patent number: 6019356Abstract: An impact absorber for decelerating a vehicle impacting on an obstacle, which impact absorber includes two tubes which can be displaced one inside the other in the manner of a telescope. The inner tube is closed off from the outside by a base and has a highly pressurized gas space and a first fluid space. A second fluid space is arranged in the outer tube and is hydraulically connected to the first fluid space via a restriction formed by a restricting aperture in an intermediate wall fixed in the inner tube. The outer tube has, in the end region, a plastic disk which melts at a predetermined temperature and as a result counteracts an explosion of the impact absorber in the event of a fire by reducing the pressure.Type: GrantFiled: July 9, 1998Date of Patent: February 1, 2000Assignee: Mannesmann Boge GmbHInventors: Metin Ayyildiz, Holger Kirchner, Jorg Schmitz
