Abstract

The invention relates to a securing element for fixing a hub of a turbine wheel and a method of assembling a hydraulic starting torque converter. The securing element (40) used for fixing a hub of the turbine wheel (6) of a hydraulic starting torque to an input shaft (2) of a gear box is provided with a sealing element (16) at an outer circumferential surface (12). The sealing element (16) extends to a housing (20) of the hydrodynamic starting converter in a mounted state such that a piston volume (26) of a piston (22) of a converter lockup clutch is sealed relative to a converter volume (30) by the seal element.

Description

technical field

[0001] Embodiments of the invention relate to a fastening element for fastening a turbine hub of a hydrodynamic torque converter to a transmission input shaft and a method for assembling a hydrodynamic torque converter. Background technique

[0002] Hydrodynamic starting torque converters are used in particular in automatic transmissions to enable starting of vehicles equipped with such torque converters. For this purpose, a hydrodynamic torque converter is arranged in the drive train between the engine and the transmission for starting the vehicle via a hydrodynamic clutch or a hydrodynamic torque converter when a gear is already engaged. In order to avoid losses caused by the torque converter principle, many hydrodynamic torque converters also have a torque converter lock-up clutch, which mechanically locks the torque converter or the hydrodynamic clutch after starting.

[0003] Typically, the torque converter is pre-assembled and provided in a pre-assembl...
