Crankshaft assembly for enabling engine cylinder deactivation |
摘要 |
A crankshaft assembly (18) for a VDIC engine (16) of an automotive vehicle (14) includes a crankshaft (44) integrated within an internal combustion engine (16). The crankshaft (44) has at least two pendulum vibration absorber assemblies (58) integrated therein. Each pendulum vibration absorber assembly (58) includes a counterweight member (60) integrally formed within the crankshaft (44). The counterweight member (60) has a desired counterweight mass for providing, in conjunction with the mass of the assembly (58), first order engine balance. The counterweight member (60) has a pendulum (64) pivotally coupled thereto. The pendulum (64) has a desired mass and geometry for attenuating torsional fluctuation.
