DETAILED DESCRIPTION This application claims the priority of German Application No.
197 47 964.
2, filed Oct.
30, 1997, the disclosure of which is expressly incorporated by reference herein.
The invention relates to a torque converter connection to a crankshaft in the drive line of a motor vehicle, for releasable connection of the crankshaft with a pump wheel.
It is already known to connect a torque converter with a crankshaft by a driver disk.
German Patent document DE 195 22 869 A1 describes such an arrangement in which the pump wheel of the torque converter is centered in the radial direction in the crankshaft.
With this type of centering of the torque converter, assembly is possible only in a difficult and expensive manner since the connection by the driver disk is produced after the crankshaft and torque converter are slid into one another.
Hence, the goal of the invention is to provide a releasable connection between a torque converter and a crankshaft in which the torque converter is fixed in the radial direction independently of the crankshaft.
This goal is achieved according to the invention by a driving connection for torque transfer in the drive line of a motor vehicle for releasable connection of a crankshaft with a pump wheel of a hydrodynamic torque converter located coaxially.
The pump wheel is supported integrally with the drive housing by a radial bearing and is mounted rotatably.
Additional embodiments of the invention are described herein.
According to the invention, a driving connection is provided for transferring torque in the drive line of the motor vehicle for releasable connection of a crankshaft with a pump wheel of a coaxially mounted hydrodynamic torque converter, in which the pump wheel is rotatably mounted integrally with the drive housing by a radial bearing.
This has the advantage that the pump wheel is centered by virtue of its support by means of the radial bearing and, therefore, no centering connection for the crankshaft is required, which simplifies assembly
