Abstract
Apparatus for the absorption of torsional vibrations of an internal combustion engine includes an input shaft between the internal combustion engine and the transmission, and a drive shaft of the transmission, which is operatively associated with said input shaft. Each of the input and drive shafts includes a torsion bar that has a lower torsional spring constant than the rest of the shaft as a whole. The apparatus further includes a rotating mass device on each of the input and drive shafts, and the apparatus is disposed between the internal combustion engine and the transmission.
Claims14
Apparatus disposed between an internal combustion engine and a gear shift transmission unit for the absorption of torsional vibrations of the combustion engine, comprising an input shaft and a gear shift transmission unit drive shaft operatively associated transversely to said input shaft, wherein each of the input and drive shafts includes a torsion bar having a lower torsional spring constant than a remainder of the shafts as a whole, and a rotating mass device on each of the input and drive shafts.
Apparatus disposed between an internal combustion engine and a transmission for absorption of rotational vibrations of the internal combustion engine, comprising:
- an input shaft disposed between the internal combustion engine and a gear shift transmission unit;
- a gear shift transmission unit drive shaft operatively associated with and arranged transverse to the input shaft, wherein each of the input and drive shafts is a torsion bar of relatively lower torsional spring constant compared to a remainder of the shaft as a whole;
- and
- a rotating mass device on each of the input shaft and drive shaft, the rotating mass devices including respective meshing gears.
A vehicle, comprising:
- an internal combustion engine having a crankshaft;
- a gear shift transmission unit, having a drive shaft;
- an apparatus having an input shaft connected with the crankshaft via a clutch, and extending transverse to the drive shaft,
- wherein each of the input and drive shafts include a torsion bar having a lower torsional spring constant than a remainder of the shafts as a whole and a rotating mass on each of the shafts.
