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. A fastening element 40 fastened to the input shaft 2 of the transmission. The rotationally symmetrical fastening element 40 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 40 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 40 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 basic geometry has a peripheral ...

Abstract

The invention relates to a fixing element for fixing a turbine hub and a method for assembling a hydraulic starting torque converter. The fastening element (40) for fastening the hub (6) of the turbine of the hydrodynamic torque converter to the input shaft (2) of the transmission has a surrounding sealing element (16) on the outer peripheral surface (12), said The sealing element (16) extends to the housing (20) of the starting torque converter in the assembled state, so that the piston of the piston (22) of the torque converter lock-up clutch is forced by the sealing element (16). The volume (26) is sealed against the torque converter volume (30).

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...
