Abstract

The present invention comprises a fixing means in a turbine assembly which is arranged in a torque converter with torsional vibration dampers and has a turbine blade (120), a turbine housing jacket (130), and a spring seat (140), wherein the fixing means comprises at least one first blade tongue (126) that extends outwards from the turbine blade (120) and is arranged in such a way that it engages in at least one first slot (132) inside the turbine housing jacket (130) and in at least one second slot inside the spring seat (140). The at least one first blade tongue (126) is arranged such that it fixes the at least one turbine blade (120) relative to the spring seat (140). Generally, the spring seat (140) comprises an internal surface (172) and an external surface, wherein the external surface is arranged such that it touches the turbine housing jacket (130) and, according to some embodiments, the at least one first blade tongue (126) is bent over such that it touches the internal surface (172).

Description

technical field [0001] The present invention relates generally to torque converters and in particular to the fastening of a spring receiver for a torque converter using tongues and to a method of producing a fastening device for a spring receiver. Background technique [0002] The present invention generally relates to a fastening device for a damper spring receptacle of a torque converter using a tongue of a turbine blade and a method for producing the fastening device. It is already known in the prior art to equip torque converters with damping springs and fastening devices. [0003] As is well known, a torque converter is used to transfer torque from an engine of a motor vehicle to a transmission. figure 1 A general block diagram is explained showing the relationship between the engine 7, torque converter 10, transmission 8 and differential / axle assembly 9 in a typical vehicle. [0004] figure 2 As shown in FIG. 6 , the pump 37 , the turbine 38 and the stator 39 are t...
