Abstract

The invention discloses a conical ring matrix material component of steel-based resin carbon fiber synchronizer and a production process thereof. According to weight percentage, 95.32 percent to 97.85 percent of atomized iron powder-100 meshes, 1 percent to 3 percent of copper powder -200 meshes, 0.5 percent to 1.0 percent of carbon powder -325 meshes, 0.6 percent of zinc stearate -325 meshes and 0.05 percent to 0.08 percent of No.20 industrial engine oil are adopted, fully mixed and die-casted to shape through a presser; after the sintering of atmosphere protection net belt, the metallic phase requirement can be met, vapor treatment, mechanical process and secondary vapor treatment are then carried out and the production process is completed. The components and the production process of the invention have the advantages of less cutting or no cutting, saving material and energy, high production efficiency and being suitable for bulk production.

Description

technical field [0001] The invention relates to a powder metallurgy process technology, in particular to a steel base resin carbon fiber synchronizer cone ring matrix raw material component and its production process. Background technique [0002] The synchronizer cone ring is the friction element of the synchronizer set up in the automobile transmission to make the shift light, reliable and prolong the service life. Close to zero, so as to realize the gear shifting without impact and light and silent at the tooth end of the active and passive parts. There are roughly two production methods for synchronizer cone rings commonly used today: one is machining, and the other is processing it from cast steel or 45# carbon steel. The material utilization rate and labor productivity of mechanical processing are relatively low; if cast steel or 45# carbon steel is used for processing, the material cost and processing cost are very high, and the production efficiency is relatively lo...
