Abstract
The invention relates to a more efficient and cost effective method of bonding pump blades and a pump hub to an impeller of a torque converter by the steps of initially assembling the pump blades and the pump hub adjacent and in close proximity to the impeller and bonding the pump hub and the pump blades to the impeller simultaneously while also eliminating the potential for surface defects through multiple heating steps. The invention includes the more efficient methods of manufacturing, but also the brazed/welded assemblies and torque converters comprising the assemblies.
Claims21
