Abstract
An assembly including a driving connection for torque transmission in a drive train of an engine by means of a shaft-hub connection. The shaft-hub connection is provided with lengthwise teeth for releasable connection of a crankshaft with a coaxial hydrodynamic torque converter. The lengthwise teeth of the shaft-hub connection have tooth cross sections that increase or decrease in the lengthwise direction of the teeth.
Claims14
Driving connection for torque transmission in the drive train of a motor vehicle, using a shaft-hub connection provided with lengthwise teeth for releasable connection of a crankshaft with a coaxial hydrodynamic torque converter, wherein the lengthwise teeth of the shaft-hub connection have tooth cross sections that increase or decrease in the lengthwise direction of the teeth,
- wherein one of the hub and shaft with lengthwise teeth is mounted on the torque converter housing.
Driving connection for torque transmission in the drive train of a motor vehicle, using a shaft-hub connection provided with lengthwise teeth for releasable connection of a crankshaft with a coaxial hydrodynamic torque converter, wherein the lengthwise teeth of the shaft-hub connection have tooth cross sections that increase or decrease in the lengthwise direction of the teeth,
- wherein an axial force is used to secure the shaft-hub connection axially, said force resulting from the internal pressure of the converter when the torque converter is operating.
An assembly comprising:
- an engine crankshaft;
- a hydrodynamic torque converter disposed coaxially with respect to the crankshaft;
- and a driving connection between the crankshaft and the torque converter;
- wherein said driving connection is a shaft-hub connection with lengthwise teeth which are tapered in the lengthwise direction of the teeth.
A method of making an assembly for torque transmission in the drive train of an engine, comprising:
- providing an engine crankshaft;
- disposing a hydrodynamic torque converter coaxially with respect to the crankshaft;
- and
- providing a driving connection between the crankshaft and the torque converter, wherein said driving connection is a shaft-hub connection with lengthwise teeth which are tapered in the lengthwise direction of the teeth.
