Traction drive device of internal combustion engine, has helical spring arranged between base and clamping unit, to urge friction element against outer jacket surface of base or inner jacket surface of lever
Traction drive device of internal combustion engine, has helical spring arranged between base and clamping unit, to urge friction element against outer jacket surface of base or inner jacket surface of lever
The traction drive device (100) has a spring element (6) which is acted upon guide rail (300) in the direction of chain (200) with a restoring force. A clamping device (1) has a lever attached to a base by a bearing pin. A helical spring is arranged between the base and the clamping unit, to urge a friction element against the outer jacket surface of base or the inner jacket surface of lever, in order to dampen the rotational movement of the lever. A rotatable contact structure for the tensioning rail (400) is provided at distal end of the lever.
