Synchror.rinp aus SinterstahlSynchror.rinp made of sintered steel

Synchronr-inge, wie sie zum Beispiel bei der Synchronisierung in Automobilgetrieben verwendet werden, müssen nicht nur mit großer Präzision hergestellt werden, sondern sie müssen auch den an sie gestellten Verschleißbeansprucnungen gewachsen sein. Um die Präzision in wirtschaftlicher Weise zu erreichen ist es bereits bekannt, derertige Synchronringe auf pulvermetallurgischem Wege, zum Beispiel au? Sinterstahl, herzustellen. V/eil diese Ringe in ihrer konischen Innenbohrung besonders stark beansprucht sind, ist es erforderlich, die Ringe mindestens an dieser Stelle noch mit einem besonders verschleißfesten Überzug zu versehen. Es besteht abe^ die Gefahr, daß die Ringe nach den Aufbringen der Verschleißschicht nicht mehr innerhalb der vorgeschriebenen Tolerrnz liegen.Synchronous rings, such as those used in the Synchronizers used in automobile transmissions do not only have to be manufactured with great precision but they also have to cope with the wear and tear placed on them be. In order to achieve the precision in an economical manner, it is already known to use them Synchronizer rings by powder metallurgy, for example on the Sintered steel. V / eil these Rings are particularly heavily used in their conical inner bore, it is necessary that To provide rings with a particularly wear-resistant coating at least at this point. There is, however, a risk that the rings after the Application of the wear layer no longer lie within the prescribed tolerance limit.

Durch die Neuerung wird ein Weg gew durch den diese Schwierigkeiten überwunden werden. NeuerungsgemaH ist beim Synchronring aus Sinterstahl mindestens die konische Innenbohrung nit einer 20 bis 100 my dicken Holybdänschicht bedeckt. The innovation provides a way through which these difficulties can be overcome. According to the innovation, at least the conical inner bore of the synchronizer ring is made of sintered steel Covered with a 20 to 100 micron thick layer of hollybdenum.
