20130330227 | Copper-Zinc Alloy for a Valve Guide - A novel copper-zinc alloy is particularly suited for a valve guide. The copper-zinc alloy is formed of 59 to 73% copper, 3.1 to 8.3% manganese, 2 to 6% aluminum, 0.5 to 2% silicon, 0.2 to 1.2% iron, and the remainder zinc and inevitable impurities. | 12-12-2013 |
20120030929 | METHOD FOR PRODUCING A COMPONENT OF A SYNCHRONIZATION DEVICE FOR A MANUAL TRANSMISSION - The invention relates to a method for producing a component of a synchronization device for manual transmissions, in particular a synchronizer ring ( | 02-09-2012 |
20110056793 | SYNCHRONIZER RING MADE OF SHEET METAL - A sheet-metal synchronizer ring for a synchronizing device has a conical ring body, an outer toothing for blocking the axial movement of a sliding sleeve, and at least one indexing tab which is bent in the axial direction and limits the rotation of the synchronizer ring in a synchronizer hub. The indexing tab has a tab widened portion on at least one side. | 03-10-2011 |
20100282565 | FRICTION LAYER CARRIER DEVICE AND METHOD FOR MANUFACTURING THE FRICTION LAYER CARRIER DEVICE - A friction layer carrier device has a basic element with a basic element contact surface and a friction layer lining body with a lining contact surface. The friction layer lining body is fastened to the basic element in such a way that the basic element contact surface and the lining contact surface are joined together in adhesive regions via an adhesive. At least one depression region, which allows degassing of the adhesive, is introduced into the basic element contact surface and/or into the lining contact surface. | 11-11-2010 |
20090280026 | COPPER-ZINC-SILICON ALLOY, PRODUCTS USING THE ALLOY AND PROCESSES FOR PRODUCING THE ALLOY - A Cu—Zn—Si alloy includes, in % by weight, 70 to 80% of copper, 1 to 5% of silicon, to 0.5% of boron, up to 0.2% of phosphorus and/or up to 0.2% of arsenic, a remainder of zinc, plus inevitable impurities.
