摘要

The drive has a drive side wheel (3) and drive wheels (4, 5) that are connected with an elastic belt (2). A tensioning system includes a console (8) with retainers, in which a tension pulley (7) is movably guided over an axis (10) for mounting the elastic belt and is position-fixed in an operating condition to the console by a screw connection (11). The console forms the retainer that is designed as prism, where the prism has an angle ranging from alpha 1 =35 to alpha 2 = 70 degrees, which adjusts the retainer between a symmetrical axis and a reinforcing surface.
