In a single- or multiple-part protective cover for traction drives (for instance, chain, belt, toothed belt drives or the like), in particular for vehicle engines, vehicle drives, machines or the like, a protection of the traction drive from impairment by excessive heating during operation and from the entry of dirt particles, rainwater, snow and other foreign bodies is attained in that at least one coolant overpressure inlet opening (2) is embodied in the walls of the protective cover (1) and communicates with at least one source emitting the pre-filtered coolant at overpressure. As a result, a gaseous coolant such as air or the like can be introduced, either permanently or temporarily, by means of a source embodied as a turbocompressor or pump or relative wind intercepting device, into the interior of the protective cover, as a result of which, first, sufficient cooling of the traction drive and, second, the formation of an overpressure in the interior of the protective cover are effected, the latter preventing the entry of any dirt particles or the like. By means of the invention, the functional capacity of the traction drive is improved substantially, and the service life of the individual components, and in particular of the traction means, is substantially increased.

A single- or multiple-part protective cover for traction drives, such as chain, belt, toothed belt drives, in particular for vehicle engines, vehicle drives, machines, comprising: at least one inlet opening disposed in the protective cover, through which opening a gaseous medium can enter into an inner chamber containing the traction drive, the at least one inlet opening being designed as an over-pressure coolant inlet opening in a wall of the protective cover; a line having one end connected with a corresponding one of the at least one inlet opening and having a second end connected to a source emitting the coolant medium, said source comprising a turbo-compressor.
