Abstract

A belt drive for a motor vehicle having at least two toothed pulleys (1) which are spaced apart from one another and having a toothed belt which wraps around them, wherein a positively locking connection is formed between a toothing system of the wraparound means and a toothing system (2) of the toothed pulleys (1), which positively locking connection is of low-friction configuration by an anti-friction agent which acts between the toothing systems is provided. In order for it to be possible to configure a toothed belt inexpensively and without an anti-friction agent, the anti-friction agent is formed in the form of a lubricant-varnish layer (5) which is applied at least to a toothing system (2) of a toothed pulley (1).
