The method of producing fixed expedient and the fixed expedient which use the tonguelike piece of the turbine blade for the attenuation spring reception section of the torque converter

摘要

As for this invention, being arranged inside the torque converter which has the torsion vibrating damper the turbine blade (120) with the turbine housing shell (130) with the spring reception section (140) with being the fixed expedient in the turbine assembly which it possesses, fixed expedient has had, one 1st blade tongue piece (126) at least, the said 1st blade tongue piece (126) having extended the turbine blade (120) from facing toward outside direction, the said 1st blade tongue piece (126) the turbine housing shell (130) the 1st slit inside (132) and the springThe reception section (140) in order to engage at least in one inside 2nd slit, it is arranged. At least one 1st blade tongue piece (126), in order the said blade tongue piece (126) at least one turbine blade (120) to lock the spring reception section (140) vis-a-vis, it is arranged. In addition, the spring reception section (140) the inside surface (172) and has had the outer part surface, the outer part surface is arranged, is bent, in order the said outer part surface the turbine housing shell (130) with to contact, at the same time at least one 1st blade tonguelike piece (126), in order the said 1st blade tonguelike piece (126) the inside surface (172) with to contact.
