  • Patent number: 10578168
    Abstract: A synchronizer ring for a synchronization unit has a substantially constant sheet-metal cone which tapers in direction of its ring axis from a first axial cone end towards a second axial cone end. At the sheet-metal cone a centering collar is integrally molded and the sheet-metal cone includes a first sheet portion and axially adjacent a second sheet portion. In addition, the sheet-metal cone includes a step portion which axially extends between the second axial cone end and the first sheet portion, wherein a radial outer side of the step portion is offset with respect to a radial outer side of the first sheet portion towards the ring axis. Furthermore, there is shown a method for manufacturing a synchronizer ring.

  • Patent number: 10519341
    Abstract: A nonaqueous coating material composition and a coating produced from the coating material composition are provided. The coating material composition contains at least one polyhydroxyl group-containing component, at least one polyisocyanate group-containing component, at least one catalyst, and at least one urethane additive (PF) which has specific groups. The urethane additive (PF) is prepared by reacting 0.5 to 20 mol % of the isocyanate groups originally present in a polyisocyanate (PI) with a component (Ia) and 10 to 99.5 mol % of the isocyanate groups originally present in the polyisocyanate (PI) with a component (IIa). The component (Ia) contains at least one perfluoroalkyl group of a specific formula and one group reactive toward the isocyanate groups. The component (IIa) contains at least one silane group of a specific formula and one group reactive toward the isocyanate groups.
