Patent ID: 10247275

Abstract:
A powertrain includes a housing and a crankshaft-balancing assembly that is at least partially disposed inside the housing. The crankshaft-balancing assembly includes a crankshaft rotatable about a longitudinal axis. The crankshaft-balancing assembly further includes a drive member secured to the crankshaft. The crankshaft-balancing assembly also includes a first shaft rotatable about a first pivot axis. The first shaft is rotatable in response to rotation of the crankshaft. The crankshaft-balancing assembly includes a weight member that extends from the first shaft. The weight member is positioned along the first shaft to balance the crankshaft during rotation of the crankshaft and the first shaft. The crankshaft-balancing assembly also includes a drive member that surrounds the first shaft and a portion of the weight member. The drive member of the first shaft defines a void that opposes the portion of the weight member.
