Beschreibung
Zusammenfassung:	A belt tensioning unit (1) having a rotatably fixed base part (2) and a tensioning part (3) which can be rotated in a limited manner in relation to the base part against the action of an energy storage unit (6) is provided. Between the base part (2) and the tensioning part (3) a friction device (8) is radially arranged between the energy storage unit (6) and a friction surface (10). The friction device is pre-tensioned by the energy storage unit (6) in a radial outward direction against the friction surface (10) when the base part (2) and the tensioning part (3) are rotated in relation to each other. In order to obtain a simple friction device (8) having improved friction properties, it is proposed to design the friction device (8) as a friction segment (9) that encloses two friction surfaces arranged symmetrically to each other and opposite of each other at the friction surface (10).
