A clamping device (2) for a starter generator belt drive of an internal combustion engine. The clamping device includes a tensioner housing (8), a tensioning arm (17) mounted movably therein, and two idlers (6, 7), one of which is mounted to the tensioning arm and the other of which is mounted to the tensioner housing (8) in a stationary manner. A spring component which generates the pre-load force includes two helical compression springs (20a, 20b) connected in series, the facing spring ends (23a, 23b) of which are separated by an intermediate piece (24) mounted in the tensioner housing in a sliding manner. The tensioning arm has a pin projection (28), which extends through the helical compression springs running inside the tensioning arm and which is mounted in the intermediate piece in a sliding manner. |
