| 摘要 |
The invention relates to a wraparound drive for an internal combustion engine, having a wraparound means ( 2 ) which is configured as a belt or a chain and is guided over drive and output wheels ( 3, 5, 6 ) of the crankshaft ( 4 ) and at least one camshaft ( 7, 8 ) of the internal combustion engine and/or auxiliary assemblies which are to be driven. In order to ensure reliable balancing of the drive by elimination of oscillations and resonances, there is provision for at least one of the drive or output wheels ( 3, 5, 6 ) or a deflection wheel ( 9 ) to be of unround or eccentric configuration, and/or for at least two tensioning rollers ( 11, 13 ) to be provided, one of these tensioning rollers ( 13 ) being provided with a damping device ( 14 ), or both tensioning rollers ( 11, 13 ) being coupled to one another by a damping device ( 14 ).
