Drive transfer device for vehicle - has effective damping between idler and drive shaft comprising preloaded contact friction surfaces

摘要

The transfer device is for a vehicle where a belt drive driven off the engine is connected to a driveshaft via an idler (1). A damper (11,13) is located between the idler and the driveshaft. The damper comprises at least one damping element (11) with at least one friction surface (11a), which is in contact with a surface (13a) rotating with the driveshaft. The two contact surfaces are loaded with a certain amount of pretension relative to each other.
