TORQUE TRANSMISSION DEVICE, SUCH AS FIXED BALL JOINT JOINTS, FUNCTIONING AS OPPOSITE JOIN JOINTS AND PROCESS FOR COMPONENT PRODUCTION FOR TORQUE TRANSMISSION

摘要

Torque transmission device, such as homokinetic fixed ball joints, functioning as opposite track joints. The present invention refers to torque transmission devices, such as fixed ball homokinetic joints, which function as opposite track joints, and a process for their production, where the curvatures of the rear of the joints' lanes, in their axial path, diverge from the curves Contact lines of the spheres. The process is characterized by the fact that the component before the formation of a longitudinal profile is elevated to a greater hardness through its tempering process, and in the longitudinal profile region,A diffusion layer is partially /completely removed.
