Patent attributes
A drive system with a drive chain which is guided over a sprocket (10), said sprocket having a sequence of teeth (11) arranged on its circumference, and which is composed of a succession of chain links (14), wherein each chain link (14) is composed of at least two link plates (15) which are arranged parallel to one another and which are connected to one another by means of link pins (16), is characterized in that the individual chain links (14) are coupled to one another by means of at least one connecting plate (18) which is arranged between said chain links and which permits a parallel displacement of the chain links (14) relative to one another, wherein each connecting plate (18) has at least one projection (19), and projections (19) and teeth (11) have in each case an angular form with rectilinearly running tooth flanks (13) and engagement flanks (20), and in that, in the case of a load-induced elongation of the connecting plates (18), the engagement flanks (20), starting with the final connecting plate (18) which is in engagement as far as the first connecting plate (18) which is passing into engagement, slide outward on the tooth flanks (13) of the individual successive teeth (11) such that the areal contact is maintained.
