  • Patent number: 4940565
    Abstract: A method serves for manufacturing frictional locking rings, in particular for stepped motor vehicle transmission synchronizing mechanisms, in which a sintered frictional coating is applied on a surface of the element and the sintered frictional coating is compacted.For simplifying the method and improving the reproducibility of the dimensions of the surface of the sintered frictional coating one first applies a frictional coating of a sintering powder in a predetermined raw dimension regarding its thickness and compacts the frictional coating thereafter under pressure to a predetermined nominal dimension.
