Publication number: 20220018390Abstract: A steering system for a motor vehicle has a worm gear set, comprising a worm wheel and a worm shaft, wherein the worm shaft is rotatably mounted at least one bearing point in a housing of the worm gear set by means of a pivot bearing. The pivot bearing has an increased load capacity compared to a pivot bearing with a single-row standard deep groove ball bearing. A pivot bearing for a steering system has an inner ring and an outer ring, wherein a plurality of rolling elements is arranged between the inner ring and the outer ring. One of the bearing rings is designed as a full ring and the other bearing ring as a split bearing ring, the split bearing ring having a first ring element and a second ring element.Type: ApplicationFiled: October 18, 2019Publication date: January 20, 2022Applicant: Schaeffler Technologies AG & Co. KGInventors: Jürgen Gebhardt, Seryas Mohammad

Patent number: 6641930Abstract: An electrically conductive metal tape for manufacturing electrical contact components and a plug connector made of it. The metal tape has a base material made of copper or a copper alloy having a metallic coating, applied by molten technology, made of a tin-silver alloy containing a silver proportion between 1% and 3.8% by weight. The silver content in the coating preferably lies between 1.2% by weight and 2.5% by weight. Especially positive properties with respect to the adhesiveness between base material and metal coating are achieved by the silver proportion in the coating. At the same time, the temperature stability and sliding properties are improved. Furthermore, a stable contact resistance is ensured.Type: GrantFiled: May 17, 2001Date of Patent: November 4, 2003Assignee: Stolberger Metallwerke GmbH & Co KGInventors: Klaus Schleicher, Albert Rumbach, Jürgen Gebhardt, Udo Adler
