Abstract
A driving coupling for the torque transmission in the transmission line of a motor vehicle includes a shaft-hub coupling provided with longitudinal toothings for the releasable coupling of a crankshaft with a coaxially arranged hydrodynamic torque converter. The longitudinal toothings of the shaft-hub coupling have tooth cross-sections which become larger and smaller respectively in the longitudinal direction of the teeth. An elastomer layer is situated at least between the tooth flanks of the shaft and the hub which transmit the torque.

Driving coupling for torque transmission in the transmission line of a motor vehicle by means of a shaft-hub coupling provided with longitudinal toothings for a releasable coupling of a crankshaft with a hydrodynamic torque converter arranged in a coaxial manner, the longitudinal toothings of the shaft-hub coupling having tooth cross-sections which become larger and smaller respectively in the longitudinal direction of the teeth
- wherein an elastomer layer is situated at least between the tooth flanks of the shaft and the hub.
A driving coupling for coupling a torque converter to a crankshaft, the driving coupling comprising:
- a shaft coupling having longitudinal teeth, the shaft coupling being connected to one of the torque converter and the crankshaft;
- a hub coupling having longitudinal teeth, the hub coupling being connected to the other of the torque converter and the crankshaft, wherein the longitudinal teeth of the shaft coupling are engageable with the longitudinal teeth of the hub coupling;
- and
- an elastomer layer positioned between tooth flanks of the shaft coupling and tooth flanks of the hub coupling.
A method of coupling a torque converter to a crankshaft, the method comprising:
- coupling longitudinal teeth of a shaft coupling connected to one of the torque converter and the crankshaft to longitudinal teeth of a hub coupling connected to the other of the torque converter and the crankshaft, wherein an elastomer layer is positioned between tooth flanks of the shaft coupling and tooth flanks of the hub coupling.
