Chain drive e.g. camshaft drive, for motor vehicle engine, has support wheels provided laterally below annular gears of two chain wheels, where support wheels are inserted into groves of drive chain and are driven with chain wheels

摘要

The drive has two chain wheels (1, 3) and a drive chain (5), in which annular gears of the wheels are displaced laterally with respect to each other in an axial direction. The annular gears are arranged within grooves of the drive chain due to the lateral displacement. Support wheels provided laterally below the gears are inserted into grooves, and are driven with the chain wheels, where the grooves are not engaged with the gears.
