摘要

The invention relates to a tensing system (1) for a means of traction (10), provided with a housing (2) and a pivotable tensing arm (4). A friction element (15a) is arranged in an annular space (17) between the tensing arm (4) and the bearing journal (3) in order to obtain an oscillating pivoting movement of the tensing arm (4) according to the direction of rotation.
