Embodiment Construction

[0026] figure 1 A sectional view of a hydrodynamic torque converter fastened to the transmission input shaft 2 is shown, and in particular a sectional view of the region in which the hub for the turbine of the hydrodynamic torque converter is arranged 6 The fixing element 4 is fixed on the input shaft 2 of the transmission. The rotationally symmetrical fastening element 4 has a central fastening hole through which extends a hollow bolt 8 which is screwed into a thread in the likewise hollow transmission input shaft 2 so that the fastening element 4 is positioned in the axial direction 10 The transmission input shaft 2 is connected to the transmission input shaft 2 in a non-movable manner relative to the transmission input shaft 2. In other words, the fastening element 4 is fixed axially 10 relative to the transmission input shaft 2 by means of the hollow screw 8 . Here, the rotationally symmetrical fastening element with a cylindrical base geometry has a circumferential seal...

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...
