Abstract: A toothed wheel system for an internal combustion engine of a motor vehicle is provided. The least one tooth system has a plurality of teeth that follow one another in the circumferential direction of the gear wheel, and at least one elastomer track adjoining the tooth system in the axial direction. The elastomer track is formed as a regular polygon on the outer circumferential side. The number of sides of the polygon correspond to the number of teeth.

Abstract: A sprocket for a chain drive, in particular a timing chain drive for an internal combustion engine, is provided. The sprocket includes a radially outer toothed ring and a damping ring. The damping ring is axially spaced apart from, and radially inside of, the toothed ring. The damping ring has a radially outer surface that is shaped to be complementary to link plates of the timing chain. The design of the sprocket results in the damping ring being subject to practically no wear, being producible from a conventional material, and being economical to produce.

Abstract: A drive unit, in particular an internal combustion engine, has a fluid line arrangement, wherein the fluid line arrangement has a cavity accessible for a fluid via a bore in a first wall element. A spacer element for the fluid line arrangement has a resilient clamping sleeve which can be introduced through the bore. The clamping sleeve has a first longitudinal section which is provided so as to remain in the bore in contact with the bore wall and a second longitudinal section which is set back from the first longitudinal section by way of at least one notch which runs transversely with respect to a longitudinal axis of the clamping sleeve. The second longitudinal section is configured as an axially slotted tube which serves as the spacer element, the borders of the slot being bent radially outwards.
