Abstract
Official abstract text for this publication.
A synchronizer hub for vehicles and a method for manufacturing the same forms an inner spline and an outer spline of a transmission synchronizer hub for vehicles by using different materials. The synchronizer hub may be manufactured by filling inner powders for forming the inner spline, molding the inner spline, filling outer powders for forming the outer spline, molding the outer spline, separating the double molded object obtained by integrally forming the inner spline and the outer spline from a mold, and performing sintering, post-processing, and high-frequency heating processes.
First claim
Opening claim text (preview).
What is claimed is: 1. A synchronizer hub for vehicles, comprising: the synchronizer hub being formed as a double molded object obtained by integrally forming an inner spline and an outer spline of the synchronizer hub by using different materials, wherein a volume fraction of pearlite in the inner spline is 80 to 89%, a volume fraction of bainite in the inner spline is 10 to 20%, a volume fraction of martensite in the outer spline is 50 to 60%, and a volume fraction of pearlite…
