Patent number: 9309943Abstract: A pendulum support is particularly suited for supporting an engine unit. The support has two mutually spaced-apart fixing elements for connecting two bodies that can be displaced in relation to one another. The fixing elements are elastically interconnected. The object is to provide a pendulum support with a high degree of deflection that is cost-effective to produce. The base body has two base body elements, which are interconnected by at least one elastic shear element. At least one of the base body elements is formed with a cavity, wherein one area of the other base body element is contained with a degree of deflection.Type: GrantFiled: September 2, 2004Date of Patent: April 12, 2016Assignee: Trelleborg Automotive Germany GmbHInventors: Arndt Graeve, Manfred Hofmann

Patent number: 8517359Abstract: A hydraulic damping mount has a working chamber and a compensating chamber, which are filled with a hydraulic liquid and separated from each other by an intermediate plate. The working chamber and the compensating chamber are connected to each other via a transfer passage and a bypass channel. The bypass channel can be opened or closed by an actuator. The actuator is configured as a one-piece elastomer part, which has a fastening portion on the edge and an actuating element, which is connected to the fastening portion via a flexible connecting portion.Type: GrantFiled: August 17, 2009Date of Patent: August 27, 2013Assignee: Trelleborg Automotive Germany GmbHInventors: Arndt Graeve, Henry Winter, Ulrich Mews, Eric Eisel

Publication number: 20130049272Abstract: An elastic bearing bush configuration is to be installed in a receptacle in particular for use in a suspension of a motor vehicle. The elastic bearing bush configuration contains an inner core, an outer sleeve, and an elastomer body connecting the inner core and the outer sleeve to each other. The outer sleeve is made of plastic. The elastic bearing bush configuration is characterized in that the outer sleeve has a press fit reinforcing element for fixing the outer sleeve in the receptacle by a force exerted directly on the receptacle by the press fit reinforcing element.Type: ApplicationFiled: October 29, 2012Publication date: February 28, 2013Applicant: TRELLEBORG AUTOMOTIVE GERMANY GMBHInventor: TRELLEBORG AUTOMOTIVE GERMANY GMBH

Patent number: 8348250Abstract: A pneumatically damping mount, in particular an engine mount for motor vehicles, includes a bearing spring of elastomeric material for supporting a mount core and delimiting a working chamber. The working chamber is filled with a gas, in particular air, and communicates with the ambient atmosphere through a nozzle opening. A progression element of elastomeric material is disposed opposite the bearing spring and delimits the working chamber together with the bearing spring, to enable further deformation of the mount after closing of the working chamber.Type: GrantFiled: September 14, 2009Date of Patent: January 8, 2013Assignee: Trelleborg Automotive Germany GmbHInventors: Manfred Hofmann, Arndt Graeve

Patent number: 8262067Abstract: A mount has a housing and a mount core. An elastomer spring supports the mount core on a housing and a receiving part is vulcanized into the elastomer spring. The receiving part has a receiving opening for the mount core. As the mount core is inserted, a preload is applied to the elastomer spring. The receiving part has at least one first core guide and a second core guide, between which the mount core is held. The receiving part also has a web which connects the core guides to one another in a first state and which is removed before or during the insertion of the mount core. The production of a mount of this type is simplified in this way.Type: GrantFiled: February 20, 2009Date of Patent: September 11, 2012Assignee: Trelleborg Automotive Germany GmbHInventor: Karl-Heinz Troyke

Publication number: 20120175831Abstract: An elastic bushing, in particular a composite steering bushing having an inner core and an outer sleeve disposed concentrically with one another, and connected to each other by an elastomer layer. A limiting element between the inner core and the outer sleeve limits the radial displacement of the inner core. The outer sleeve has an inwardly bent end region. In order to provide a cost-effective elastic bushing providing clearance in the radial and axial directions, the inner core is formed with at least one molded recess in the axial direction, the at least one limiting element is positively inserted in the recess, the limiting element is at a distance from the end region in the axial direction, and the end region limits the axial displacement of the inner core.Type: ApplicationFiled: September 7, 2010Publication date: July 12, 2012Applicant: TRELLEBORG AUTOMOTIVE GERMANY GMBHInventor: Jerome Kieffer

Publication number: 20120152670Abstract: A damping device for a motor vehicle is particularly suited for damping starting and stopping impacts of a motor vehicle engine. The device has first and second chambers filled with a damping medium and separated by an intermediate plate. The chambers are each bounded by a bellows and by a face plate. A damping channel connecting the chambers is formed in the intermediate plate. In order to achieve a damping effect depending on the operating mode of the motor vehicle engine, the two chambers are connected by at least one bypass channel, which can be selectively opened or closed by way of a switchable valve. The switched state of the valve depends on the operating mode of the motor vehicle. There is also described a damping system for damping the starting and stopping impacts of a motor vehicle engine.Type: ApplicationFiled: July 12, 2010Publication date: June 21, 2012Applicant: TRELLEBORG AUTOMOTIVE GERMANY GMBHInventors: Ludovic Chauvet, Arnaud Gattepaille

Publication number: 20100013132Abstract: An elastic bearing bush, particularly for use in a chassis of a motor vehicle, has a housing, a core disposed inside the housing, and an elastomer body connecting the housing to the core. The bearing bush has different damping properties in a first spatial direction and a second spatial direction. The bearing bush has a substantially rectangular base surface. The spring and damping properties are determined in the first spatial direction by at least one air spring element and in the second spatial direction by at least one elastomer spring.Type: ApplicationFiled: September 29, 2009Publication date: January 21, 2010Applicant: TRELLEBORG AUTOMOTIVE GERMANY GMBHInventor: Arndt Graeve
