Patent number: 5088580Abstract: A hydraulically acting damping element includes a main chamber and a compensation chamber. Two rigid end walls and a rubber-elastic circumferential wall surround one of the chambers. An elastic, pressure-stable bellows has ends and a circumference. The bellows is disposed concentrically inside the one chamber and rigidly joined to the end walls with the main chamber inside the bellows and the compensation chamber between the bellows and the circumferential wall. An over-flow circuit is formed on one of the ends of the bellows and extends over at least part of the circumference of the bellows for hydraulically connecting the main chamber and the compensation chamber.Type: GrantFiled: May 10, 1990Date of Patent: February 18, 1992Assignee: Metzeler GmbHInventors: Manfred Grothe, Volker Hartel

Patent number: 5066780Abstract: A heat transfer liquid in the form of a molten salt mixture includes a mixture of potassium nitrate and lithium nitrate, and added calcium nitrate and/or anhydrous salts if appropriate. This is done in order to achieve a low melting point, a low toxicity and in particular a low viscosity. The heat transfer liquid may be used in the vulcanization of rubber.Type: GrantFiled: October 12, 1989Date of Patent: November 19, 1991Assignee: Metzeler GmbHInventor: Werner Michel

Patent number: 5050702Abstract: A chassis mount for a vehicle having a chassis and a wheel suspension includes an approximately frustoconical rubber body having a lower surface and being retained in the chassis. A central bushing is disposed inside the rubber body. A bolt has ends and is guided in the central bushing. A fork structure articulatingly connects the ends of the bolt to the wheel suspension. A hydraulically damping mount element has two liquid chambers communicating with one another through an overflow conduit. The chambers include a working chamber with an upper surface. The hydraulically damping mount element is mounted as a modular component onto the lower surface of the rubber body with the lower surface of the rubber body forming the upper end surface of the working chamber.Type: GrantFiled: February 26, 1990Date of Patent: September 24, 1991Assignee: Metzeler GmbHInventor: Wolfgang Sauer

Patent number: 4942075Abstract: An annular resilient body of fiber composite material for vibration-insulating support of drive assemblies includes at least one wound body having a circumferential direction and a loading direction. The at least one wound body includes a plurality of wound concentric layers formed of synthetic resin impregnated fibers extending in the circumferential direction and transverse to the load direction, and at least one layer of fibers extending at an angle relative to the concentric layers. Force-inducing fastening elements are disposed on two opposite sides of the at least one wound body. The fastening elements are formed of metal brackets at least partly encompassing the at least one wound body and elastic rubber layers bracing the metal brackets against the at least one wound body.Type: GrantFiled: July 24, 1989Date of Patent: July 17, 1990Assignee: Metzeler GmbHInventors: Volker Hartel, Carl Heynemann, Werner Hundt, Siegfried Muller, Matthias Richter

Patent number: 4921232Abstract: A hydraulic-damping engine mount includes a working chamber, a frustoconical elastomeric support spring surrounding the working chamber, a compensating chamber, and a soft-elastic cup-shaped diaphragm bordering the compensating chamber. A partition is disposed between the chambers. The circular-annular overflow conduit through which the chambers hydraulically communicate with each another has a substantially rectangular cross section and is in the vicinity of the partition. At least one rib-like intermediate wall inside the overflow conduit extends in the circumferential direction and extends vertically over a portion of the height of the overflow conduit.Type: GrantFiled: September 12, 1988Date of Patent: May 1, 1990Assignee: Metzeler GmbHInventor: Manfred Hofmann

Patent number: 4921049Abstract: A hydraulic-damping two-chamber engine mount includes a working chamber and a compensating chamber. A conical jacket-like elastomeric wall has an end surface and a bearing plate is disposed on the end surface and borders the working chamber along with the elastomeric wall. The bearing plate has a cylindrical attachment with an end protruding into the working chamber. A rigid intermediate plate has an overflow conduit formed therein providing communication between the chambers. An integrated tension stop in the form of an annular stop plate has an inner edge suspended with play on the end of the cylindrical attachment for damping axial and radial mobility of the stop plate. A substantially conical jacket-like stop ring is provided for engaging the stop plate from above.Type: GrantFiled: March 16, 1989Date of Patent: May 1, 1990Assignee: Metzeler GmbHInventors: Franz-Josef Kaiser, Wolfgang Sauer

Patent number: 4882944Abstract: A torsional vibration damper includes a hub to be mounted on a crankshaft and a flywheel ring having an outer surface. The hub and the flywheel ring each have the shape of a deformed flat, annular, disk-shaped sheet metal blank. A substantially radially extending rubber track connects the hub to the flywheel ring. A V-belt carrier molded from sheet metal and/or a transducer wheel are secured at least on the outer surface of the flywheel ring.Type: GrantFiled: July 7, 1988Date of Patent: November 28, 1989Assignee: Metzeler GmbHInventor: Hans-Jurgen Vohl

Patent number: 4852864Abstract: A hydraulic-damping two-chamber engine mount includes a working chamber facing toward an engine, a compensating chamber, and an intermediate plate separating the chambers from each other and having an overflow conduit extending helically therein through which the chambers communicate hydraulically with one another. The intermediate plate has two sides and an outer periphery merging into a cylindrical ring extending beyond both of the sides. The ring has an outer surface with two axially superposed conduits formed therein having ends and extending over at least a portion of the outer periphery of the intermediate plate. The intermediate plate has a longitudinal axis and has a conduit portion formed therein extending obliquely relative to the longitudinal axis through which one end of each of the superposed conduits communicate with each other. An outer conduit wall in the form of a cylindrical mount housing has an inner wall surface covering the superposed conduits.Type: GrantFiled: September 19, 1988Date of Patent: August 1, 1989Assignee: Metzeler GmbHInventors: Horst Bitschkus, Manfred Hofmann, Karl-Heinz Klockner, Uwe Nelles, Gunther Siewert

Patent number: 4846917Abstract: A method for producing and vulcanizing an inflatable hollow body from a double cloth having upper and lower plies with edges and pile yarns spacing the plies apart includes applying a respective gas-tight unvulcanized layer of rubber to each of the upper and lower piles of the double cloth. The edges of the upper and lower plies are joined with angle braces forming a hollow body. The hollow body is evacuated over a predetermined period of time and the hollow body is vulcanized in the evacuated state.Type: GrantFiled: September 16, 1987Date of Patent: July 11, 1989Assignee: Metzeler GmbHInventors: Volker Hartel, Gerhard Hoglinger, Hans Schreiber
