A pulley unit, in particular for an internal combustion engine, comprises a hub (3) for a driving shaft, a ring-shaped element (5) externally coaxial to the hub (3) and having a seat for the engagement by a belt, and a connection device (14, 15) interposed...

The tensioning device has a driving roller (10) and a turning roller (11). When the engine is started, the second roller is turned by a generator (5) included in the belt drive. Due to the load length (6ST) thus created, the driving roller is displaced aga...

Internal combustion engine (1) comprising a crankcase (2), a crankshaft (4), a mid-shaft (27), at least one cylinder (22) and at least a first and a second auxiliary machine (36,37) wherein the crankshaft (4) and the mid-shaft (27) are drivably connected t...

This internal combustion engine suitable for installation in a motor vehicle with auxiliary assemblies, which comprise, for example, an alternator and a water pump, are arranged on an outer side of a housing structure of the internal combustion engine. In ...

As a conventional mounting structure, it was provided an auxiliary machine mounting structure for an engine such that a plural mounting portions formed integrally on the outer circumferential surface of an auxiliary machine and a bracket (a portion to be m...

The invention relates to balance shafts for internal combustion engines which have circulating balance masses for compensating free inertia forces and/or moments, which are driven in a fixed transmission ratio to the crankshaft and simultaneously form the ...

In a tensioning device (S) for a flexible drive element (E) such as a belt or chain of a drive (T) of an internal combustion engine connecting at least a crankshaft and a starter/generator (SG), a first and a second tensioning roller (R1, R2) are provided ...
