A chain drive, especially to a camshaft/camshaft drive for a motor vehicle
engine, comprising at least two chain wheels and one drive chain. The
gear rims of the at least two chain wheels are arranged to be laterally
offset to each other in the axial direction. The chain drive is performed
as a multiple chain, wherein each of the offset gear rims of the chain
wheels have their own track of the multiple chain due to the lateral
displacement of the gear rims. The tip diameters of the offset gear rims
and the chain wheels are overlapping. At least one support wheel is
provided laterally next to a gear rim of an associated chain wheel, which
engages into the empty track of the multiple chain not engaged with the
gear rim of the associated chain wheel and is driven together with the
associated chain wheel.
